The liquid fuel rockets belonging to Goddard (1926).

Video Timeline of United States inventions (1890-1945)

Era Progresif (1890-1919)

1890 Stop sign

The stop sign is a traffic sign, usually installed at a crossroads like a four-way intersection, which instructs the driver to stop and then continue only if the path ahead is clear. The idea of ​​placing stop signs at the crossroads was first compiled in 1890 when William Phelps Eno of Saugatuck, Connecticut proposed and drafted the first set of traffic laws in an article published in Rider and Driver. However, the first use of stop signs did not appear until 1915 when officials in Detroit, Michigan put up a stop sign with black letters on a white background. Over the years and with many changes made to stop signs, current versions with white letters on a red background used in the United States as well as copied in many other countries around the world today, are not being used. until the Joint Committee on the Uniform Traffic Control Kit adopted the design in 1975.

1890 Tabs Machine

The tabulation machine is an electrical device designed to assist in summarizing information and, then, accounting. The tabulated results are electrically coupled with the sorter when displayed on a clock-like clock. The concept of automated data processing has been born. In 1890, Herman Hollerith invented a mechanical tabulation machine, a design used during the 1890 Census which stores and processes demographic and statistical information on hollow cards.

1890 Wheat ripped

• Wheat abon is a kind of whole-wheat breakfast cereal. Wheat slices also come in a variety of frozen , which has one side coated with sugar and usually gelatin. Abon wheat was discovered in 1890 by Henry Perky of Watertown, New York.

1890 Babcock test

• Babcock test is the first, cheap and practical test used to determine the fat content of milk. Invented by Stephen Moulton Babcock in 1890, the test was developed to prevent dishonest farmers who could, until the 1890s, water their milk or remove the cream before selling it to factories because milk was paid on volume.

1890 smoke detector

• Smoke detectors are devices that detect smoke and emit signals. Most smoke detectors work either with optical detection or by physical processes, but some of them use both detection methods to increase smoke sensitivity. Smoke detectors are usually turned on by the battery while some are connected directly to the mains, often have batteries as backup power supplies if the mains fails. The first automatic electric fire alarm was invented in 1890 by Francis Robbins Upton and Fernando J. Dibble. Upton and Dibble issued US patent # 436.961. Upton is a colleague of Thomas Alva Edison, although there is no evidence that Edison contributed to this discovery.

1891 Ferris wheel

The Ferris Wheel is a non-building structure, consisting of an upright wheel with a passenger gondola attached to the ream. Opened on June 21, 1893 at the Chicago World Expo, the original Ferris Wheel was created two years earlier by Pittsburgh, Pennsylvania, George Washington Gale Ferris Jr. bridge maker in 1891.

1891 proses Dow

The Dow process is a method of electrolysis of bromine extraction from brine, and Herbert Henry Dow's second revolutionary process to produce commercial bromine in 1891.

1891 Tesla coil

The Tesla coil is a type of resonance transformer circuitry created by Nikola Tesla around 1891. Nikola Tesla uses this coil to perform innovative experiments in electric lighting, phosphorescent, x-ray generation, high-frequency alternating current phenomena, electrotherapy, and transmission of electrical energy without cables for point-to-point telecommunications, broadcasting, and power transmission.

1891 Rotary dial

• Rotation play is a device installed in or on the phone or switchboard designed to transmit electrical pulses, known as pulse dialing, according to the number dialed. The earliest form of rotary dial used lugs on finger plates instead of holes. The rotary play was created by Almon Brown Strowger in 1891. Strowger filed a US patent # 486,909 on December 21, 1891 which was later issued on 29 November 1892.

1891 Fork Pastry

• The cake fork, also known as "cake fork", is a fork designed to eat pastries and other desserts while holding a plate. The fork has 3 or 4 tines. 3 tine forks have larger tine, flat and tilted on the side while 4 tine forks have tine 1 and 2 connected or bridged together and tilted. On July 7, 1891, Anna M. Mangin of Queens, a district in New York City, filed the first patent for a cake fork. US patent # 470,005 was then issued on March 1, 1892.

Schrader valve 1891

The Schrader valve consists of a hollow cylindrical metal tube, usually brass, with a threaded outer end. The tip of the interior takes various forms depending on the application. At the center of the exterior end is a metal pin pointing along the tube axis; the end of the pin is flush with the end of the valve body. Generally, all Schrader valves are used on tires. They have threads and bodies of a single standard size at the outer end, so hats and tools are generally universal for valves on all pneumatic tires of cars and bikes. Also, pressure valves can be used on Schrader valves instead of caps to measure pneumatic tire pressures. In 1891, George Schrader, son of German-American immigrant August Schrader, discovered Schrader's valve. The patent was issued on April 11, 1893.

1892 Bottle cap

• Bottle caps, or covers, are used to seal open bottle openings of many types. They can be small circular pieces of metal, usually steel, with plastic backing, and for plastic bottle plastic caps used instead. Hats can also be plastic, sometimes with a pour spout. Flip-Top Close like Flapper closure provides controlled dry product expenditure. The crown cork, the first form of the bottle cap, has a bent flanges over a closed bottle to suppress the liquid in it. It was created and patented in 1892 by William Painter of Baltimore, Maryland.

1892 Dimmers

• Dimmers are devices used to vary the brightness of light. By reducing or increasing the RMS voltage and hence the average power to the lamp is possible to vary the intensity of the light output. Although variable voltage devices are used for a variety of purposes, dimmers are specifically devices intended to control lighting. Dimmers are popularly used in places such as cinema, stage, dining room, restaurant, and auditorium where the need or absence of light during activities requires constant change. Dimmer was created in 1892 by Granville Woods.

1892 Bicycle seat (padded)

• A bike seat, unlike a bicycle saddle, is designed to support the rump and back of the racer, usually in a semi-recumbent position. First known as "Garford Saddle", a cushy bike seat was discovered in 1892 by Arthur Lovett Garford of Elyria, Ohio.

1892 internal combustion powered tractor Tractors are special agricultural vehicles specially designed to provide high traction at slow speeds, for the purpose of transporting trailers or machines used in agriculture or construction. Agricultural equipment can be pulled back or mounted on a tractor, and the tractor can also provide resources if the tool is mechanized. While steam-powered tractors were built earlier, In 1892, John Froelich invented and built the first gasoline-powered tractor in Clayton County, Iowa.

1893 Zipper

Zippers are a popular tool to temporarily join the two sides of the fabric. The zipper is found in trousers, jeans, jackets, and luggage. Whitcomb L. Judson is an American mechanical engineer from Chicago who was the first to discover, understand ideas, and build a workable zipper. Using a hook-and-eye device, Judson intended for this early form of zippers to be used on shoes. He also understands the idea of ​​slide binding mechanisms in conjunction with the invention of the zipper. Patents issued to Judson for zips in 1891, 1894, and 1905.

1893 Spectroheliograph

Spectroheliograph is an instrument used in astronomy that captures photographic images of the Sun at one wavelength of light, a monochromatic image. The spectroheliograph was invented in 1893 by George Ellery Hale and independently later by Henri Alexandre Deslandres in 1894.

1893 Pinking scissors

• Pinking scissors are a type of scissor that has a straight-saw blade. Used for cutting woven fabrics, pinking scissors leave a zigzag pattern instead of a straight edge. The earliest patent for pinking scissors is US patent # 489,406 issued to Louise Austin from Whatcomb, Washington on January 3, 1893.

Beginning of the 1890s Phantoscope

• The film projection machine made by Charles Francis Jenkins in the early 1890s. The Jenkin engine is the first projector that allows any silent frame of the film to be illuminated long enough before progressing to the next frame sequence.

1894 Stadimeter

Stadimeter, an optical rangefinder, is an optical device for estimating ranges to known altitude objects by measuring angles between the top and bottom objects as observed on the device. It is similar to a sextant, where the device uses a mirror to measure the angle between two objects but differs in calling that at the height of the object. Stadimeter was discovered in 1894 by Bradley Allen Fiske, a Rear Admiral in the United States Navy. The first marine test, conducted in 1895, shows that it is equally useful for sailing fleets and for navigation. Likewise, the stadiums proved useful during the Manila Bay Battle during the Spanish-American War. US patent # 523,721 was issued to Fiske on July 31, 1894.

1894 Mousetrap

A mouse trap is a special kind of animal trap designed primarily to catch mice. However, it can also trap other small animals. Mousetraps are usually arranged in an indoor location where there is an alleged rodent infestation. The first mousetrap was invented by William C. Hooker of Abingdon, Illinois, exactly three years before James Henry Atkinson developed a prototype called "Little Nipper". Atkinson might see Hooker's traps in stores or in advertisements, and copy them as the basis for his own model. Hooker received US patent # 528671 for his discovery, a mousetrap, in 1894.

medical gloves 1894

Medical gloves are disposable gloves used during inspection and medical procedures that help prevent contamination between nurses and patients. Medical gloves are made of various polymers including latex, nitrile rubber, vinyl and neoprene; they come without powder, or powder with cornstarch to lubricate the glove, making it easier to put in the hand. In 1894, William Stewart Halsted, Head of Johns Hopkins Hospital Surgery, invented medical gloves in an attempt to make medical care safer and more sterile for patients and health care workers.

1895 Cyclocomputer

A cyclocomputer or cyclometer is a device mounted on a bicycle that calculates and displays travel information, similar to an instrument on the car's dashboard. A computer with a screen, or head unit, is usually attached to the handlebar for easy viewing. In 1895, Curtis Hussey Veeder invented the cyclometer.

1895 No Clip Pedal

• The non-clip pedal is a bicycle pedal that requires special cycling shoes with cleats mounted to the soles, which lock the mechanisms on the pedals and thus holds the shoes firmly to the pedal. Most clipless pedals lock into a cleat when stepping firmly and opening when heels are twisted out, although in some cases locking mechanisms are built into cleats instead of pedals. The clipless sword was created in 1895 by Charles Hanson of Peace Dale, Rhode Island.

1895 Flights

Volleyball is an Olympic sport where two teams of 6 active players are separated by nets. Each team tries to score points against each other by grounded balls in another team's court under organized rules. William G. Morgan invented the sport first known as "Mintonnette" in 1895 while studying at the YMCA in Holyoke, Massachusetts. It was later renamed volleyball by Alfred S. Halstead.

1897 cotton candy

Candy cotton is a soft candy made from heated sugar and spun into thin yarn that looks like cotton. It was created in 1897 by William Morrison and John C. Wharton, a candy maker from Nashville, Tennessee.

1897 Muffler

Muffler is a tool to reduce the amount of noise emitted by the machine. In the internal combustion engine, engine exhaust spurts through the exhaust. The internal combustion engine muffler was invented by Milton O. Reeves who received the patent in 1897.

1897 Tapered roller bearings

• Tapered roller bearings are pads that can pick up large axial forces and are able to retain large radial forces. They were co-created by Henry Timken and Reginald Heinzelman from Germany-America. On August 27, 1897, Timken and Heizelman filed a US patent # 606,635 issued to them together on June 28, 1898.

1897 Ice cream scoop

• Ice cream scoop is a special spoon used to serve and serve ice cream. Most ice cream spoons are half-spherical and contain mechanical tools to force ice cream out of a spoon. Ice cream spoon was invented by African-American Alfred L. Cralle issued US patent # 576,395 on February 2, 1897.

1897 Charcoal briquettes

• Charcoal briquettes, or briquets are burning charcoal blocks used as fuel to start and maintain fire, primarily used for food preparation on open flames or barbecues. Charcoal briquettes are made using a process consisting of compressing charcoal, usually made of sawdust and other wood byproducts, with binders and other additives. The binder is usually starch. Some charcoal briquettes can also include brown coal, mineral carbon, borax, sodium nitrate, limestone, raw sawdust, and other additives such as paraffin or petroleum solvents to help ignition. The design of charcoal briquettes was invented and patented by Ellsworth B. A. Zwoyer in 1897.

1897 Billiards of lime cue

• Cue chalk is the base of calcite or carbonate applied to the end of the pool cue used in billiards to allow players to reduce friction between gestures and bridge hand during shooting, as well as for smoother strokes. Lime of the cue tip was coined in its modern form by the straight rig bills of William A. Spinks and the chemist William Hoskins in 1897. US patent # 578,514 for chalk cue was issued to Spinks and Hoskins on March 9, 1897.

1898 Corn candy

Corn candy is a confection in the United States and Canada, popular especially in the fall around Halloween, which mimics the shape and color of the corn kernels - broad yellow tip, center of tapered orange, and pointed white tip. Corn candy is made mainly from sugar, corn syrup, artificial coloring and binding. It is generally assumed that George Renninger, an employee of the Wunderlee Candy Company, discovered a corn candy in the 1880s. However, the earliest references credit the Goelitz Noise Company, now known as Jelly Belly Candy Company, to introduce corn candies or "chicken feed" to the American public in 1898.

1898 Remote control

Remote control is an electronic device used to operate any machine, such as television, remotely. Many of these remote communicates to their respective devices via infrared signals and radio controls. At Madison Square Garden, at the Electrical Show, Nikola Tesla gave the first demonstration of a water-driven boat, controlled by his remote control which he designed using radio signals. Tesla received a patent for his invention in 1898.

1898 Semi-automatic rifle

• A semi-automatic shooting rifle, or self-loading is a firearm that only requires a trigger for every round fired, unlike a single action gun, pump action weapon, firearm bolt action, or firearm shooting action , all of which require the shooter to space each lap in a row manually. In 1898, John Moses Browning invented the first semi-sutomatic shot gun, then patented it in 1900. Calling it Auto-5, semi-automatic Browning relied on a long recoil operation. This design remained a dominant form in semi-automatic rifles for about 50 years, a widely used and preferred weapon of choice among soldiers who fought in World War I. Auto-5 production ceased in 1999.

1898 Semi-trucks

• A type of truck connected to a removable semi-trailer carrying goods. Developed by Alexander Winton as a means of transporting cars without wasting their mileage.

1898 Archive Cabinet (vertical)

• Archive cabinets are office furniture that is normally used to store paper documents in file folders. In the simplest sense, it is the cage for the drawer where the items are stored. A vertical filing cabinet has a drawer that extends from the short side (usually 15 inches) from the cabinet. The vertical archive cabinets were created by Edwin G. Seibels in 1898, thus revolutionizing record keeping and archiving efficiently by creating space for offices, schools, and businesses.

1898 bit installer

• The installer bits are a type of drill spin for use with portable hand power tools. The install bit is also known as the binder bit or bit of the fishing line. The main distinguishing feature of the installer bit is the transverse holes that are drilled through the web from bits near the end. Once the bit has penetrated the wall, the wire can be threaded through this transverse hole, and slightly pulled back through the drilled hole. The installer bit was created and patented by Sinclair Smith from Brooklyn, New York in 1898.

1898 Sousaphone

• Sousaphone, sometimes referred to as tuba marching, is a usable tube that is derived from the hÃÆ'Â © licon. It is designed in such a way that it fits around the wearer's body and so can be easily played while being worn. Sousaphone is named after John Philip Sousa but discovered by C.G. Conn in 1898.

1899 Warping wings

Wing warping consists of twisting the wing of the plane to produce lateral control. The entire wing structure rotates slightly in the helical motion in the desired direction. The wing warping concept was associated with Wilbur Wright who, in 1899, came up with the idea and with the conclusion that the plane windings could be controlled by the wing's motion. Exemplified by turning a long narrow box, the Wright brothers put curved wings at their 1899 launchers who used the ropes to pull wings. Later, the young French engineer Robert Esnault-Pelterie replaced the wing warping in 1904 with an aileron on a copy he made from the 19th-century Wright glider. However, it was Henry Farman, a French aviator, who first used the aileron as an integral part of the wing structure in place of warping wings in 1908.

1899 Flash-lamp

An electric flash is a device that uses electrical circuits to trigger a fuse to ignite explosive powders such as magnesium, for short bursts of bright "flash" light from the chemical reaction of flash burning powder. It was mainly used for flash photography at the beginning of the 20th century, but it has other uses as well. Flash light was created and patented on November 7, 1899 by New York City resident, Joshua Lionel Cowen.

1900 bowling bowling

Duckpin bowling is a bowling variation that uses a ball that is significantly smaller than a ten pin bowling, weighing 1-3 kg (2.2-6.6 pounds) each, which has no finger holes. Pin is also shorter and lighter than equivalent pins. Therefore, when the pins are torn down, they resemble "flock of flying ducks". While the rules remain almost identical to the Ten pin game, one change rule has been made: A bowler is allowed to use three bowls at each turn. The attack will still attack and spare parts still save, but when all the pins are dropped on the third ball, it counts as a score of ten. During the summer of 1900, some cheats at Diamond Alleys in Baltimore, Maryland thought it might be interesting to change the pin size to fit the 6 inch ball. So, the inventor of bowling bowling, John Van Sant, used a wooden spinner to do just that.

1900 Nickel-zinc batteries

• The nickel-zinc batteries are a type of rechargeable battery that can be used in cordless power tools, cordless phones, digital cameras, operated grass batteries and garden tools, professional photography, flashlights, electric bicycles and electricity light vehicle sector. In 1900, Thomas Alva Edison filed a US Patent # 684,204 for a nickel-zinc battery. It was issued on October 8, 1901.

1900 Merrill-Crowe Process

• The Merrill-Crowe process is a separation technique for removing gold from a cyanide solution. The basic process was conceptualized and patented by Charles Washington Merrill around 1900, then refined by Thomas B. Crowe, working for the Merrill Company.

1900 Carbide lamps

• The carbide lamp, also known as acetylene gas lamp, is a simple lamp that generates and burns acetylene made by the reaction of calcium carbide with water. The first carbide lamp was invented and patented in New York City on August 28, 1900 by Frederick Baldwin.

1900 Flies hitter

• The fly swatter is a handheld device for hitting and killing flies and other insects. The first modern fly destroyer was invented in 1900 by Robert R. Montgomery, a businessman based in Decatur, Illinois. On January 9, 1900, Montgomery issued US patent # 640,790 for "Killer-Fly".

1900 Retrieving Pails

• An umbrella is a short nail or pin with a rather large, round head made of metal used to bind documents to the background for public display and which can be easily inserted or removed by hand. The blow was discovered by Edwin Moore around 1900, the year in which he founded the Moore Push-Pin Company.

1901 Key punch

• Keypunch is a device for manually entering data into hole cards by precisely punching holes in locations determined by the button being hit by the operator. The initial keypunch is a manual device. Then the keypunches are mechanized, often resembling a small table, with a keyboard similar to a typewriter, and with a carriage for a blank card and stacker for a hollow card. In 1901, Herman Hollerith invented and patented a mechanically operated lock key, such as a typewriter, and which advanced the card automatically to the next column after each hit. The next model is a motor that is driven by the features of imperfect programming.

1901 Mercury vapor lamp

• Mercury vapor lamps are gas discharge lamps that use mercury in an excited state to produce light. Arc discharge is generally confined to small fused quartz arc tubes mounted in larger borosilicate glass balls. The outer ball may be clear or coated with phosphorus. In both cases, the outer bulb provides thermal insulation, protection from ultraviolet radiation, and convenient installation for fused quartz arc tubes. In 1901, Peter Cooper Hewitt invented and patented mercury vapor lamps.

1901 Assembly line

Used globally around the world, assembly lines are manufacturing processes where replaceable parts are added to the product sequentially to make the finished product faster than with the older method. This type of manufacturing greatly reduces the amount of time required to assemble a product, thereby reducing the cost of production, materials, and labor so that the cost of an affordable product can be passed on to the consumer. According to a book titled Michigan Yesterday & amp; Today written by Robert W. Domm, the assembly line and its basic concept is credited to Ransom Olds, who used it to build the first mass-produced car, Oldsmobile Curved Dash. Olds patented the assembly concept, which he placed at the Olds Motor Vehicle Company in 1901. This development was often overshadowed by Henry Ford, who perfected the assembly line by installing an actuated conveyor belt that could produce the Model T in ninety-three minutes.

1901 Security razor (disposable)

The razor shaver protects the skin from all sides except the tip of the blade while shaving the skin. King Camp Gillette, a hardware seller around Fond du Lac, Wisconsin invented a disposable razor that could be attached to a reusable razor handle. Previously, a blunt razor was brought to the barber to sharpen. With a double-edged and disposable Gillette knife, uniform shaving on a man's face can be achieved with a new knife and discarded after use. Gillette applied for a patent in 1901. It was awarded in 1904.

1901 Window envelopes

Windowed envelopes are conventional envelopes with plastic windows to allow the recipient address to be printed on the paper contained therein. Window envelopes save on printing costs or workforce addressing, and in addition to saving time in setting up messages to send when custom addresses are already on the paper itself. Call it "outlook envelope", Americus F. Callahan of Chicago is the first to patent a window envelope. US Patent # 701,839 filed on December 9, 1901 and issued on 10 June 1902.

1901 Radio search finder

Radio direction finder (RDF) is a device for finding directions to a radio source. Because of the radio's ability to travel very long distances and "above the horizon", it makes excellent navigation systems for ships, small boats, and aircraft that may be somewhat away from their destination. Radio direction finder is the earliest form of radio navigation. It was first patented by the American physicist John Stone Stone. He filed on January 23, 1901 and granted a patent (US Pat. 716.134) on December 16, 1902.

1902 Hearing Aids

• Hearing aids are electro-acoustic body devices that usually fit inside or behind the wearer's ear, and are designed to amplify and modulate sounds for the wearer. Although hearing aids in some form or mode such as ear trumpets were developed in previous years, the first hearing aids were invented by Miller Reese Hutchison in 1902.

1902 Post Meter

• The postage meter is a mechanical device used to create and apply physical proof of shipment, or postage, to the material submitted. The postage meter is governed by the country postal authority; for example, in the United States, the United States Postal Service imposes rules for the manufacture, support, and use of postage meters. A postage meter implements a certain amount of postage, functions as a stamp, cancellation and postmark dated all in one. The postage meter created by Chicago inventor Arthur Pitney received a patent for this invention on October 14, 1902.

1902 Teddy bear

• The teddy bear is a teddy bear doll. They are usually filled with soft cotton and have soft and soft fur. This is the eternal form of stuffed animals that have become collectibles. The first teddy doll was invented in 1902 by Morris Michtom, owner of the Brooklyn toy shop, inspired by the political cartoon Clifford Berryman Drawing Lines in Mississippi depicting Theodore President "Teddy" Roosevelt in a life-saving hunt in Mississippi black bear boy Louisiana. Michtom requested and received President Roosevelt's permission to use his name for a hand-stitched bear called "Teddy bears" which he found and his wife helped build.

1902 Periscope (collapsible)

• Periscope is an instrument for observation of hidden positions, known for use in submarines. In a simple form, it is a tube at each end of a mirror arranged parallel to each other and at an angle 45 with a line between them. Periscopes allows the submarine, sinking in shallow depths, to search for targets and threats in the sea and surrounding air. When not in use, the periscope is pulled into the stomach. A sub-commander in tactical condition must exercise wisdom when using his periscope, as he creates observable and detectable wakes onto the radar, giving sub positions. The discovery of a periscope folded for use in a submarine warfare was credited to Simon Lake in 1902, calling its device an omniscope or a scalomniscope. Then, it is made to be raised and rotated by hand.

1902 Mercury arc valve

• The mercury arc valve is a type of electric rectifier that converts alternating current into direct current. These type of rectifiers are used in industrial electric power supplies, in electric trains, trams, and diesel-electric locomotives. They also found use in static inverter stations and as rectifiers for transmitting high current direct voltage power. Mercury arc rectifier was created by Peter Cooper Hewitt in 1902.

1902 Air Conditioning

Air conditioning is cooling and de-humidifying indoor air for thermal comfort. Using the coil system as a solution to cool and remove moisture from the humid air at the printing plant which is a wrinkled magazine page, Willis Carrier invented and produced the world's first mechanical air conditioning unit in 1902. Operator discovery - includes the first system that provides man-made control over temperature, humidity, ventilation and air quality, was first installed as a solution to the quality problems experienced at the Brooklyn printing plant, Sackett-Wilhelms Lithographing and Publishing Company. Air conditioning not only gives birth to companies and industries, but also brings profound economic, social and cultural changes.

Tea Bag 1903

Tea bags are small pouches made of paper, silk or nylon containing tea leaves to brew tea. The tea bag was created by Thomas Sullivan around 1903. The first tea bag was made of silk. Sullivan is a tea and coffee merchant in New York who started packing tea samples in small silk bags, but many customers brew tea in them.

1903 Offset printing machine

• Offset printing is a commonly used printing technique in which inked images are transferred from the plate to the rubber blanket, then to the print surface. Ira Washington Rubel invented the first offset printing machine in 1903.

1903 Aircraft

A fixed wing aircraft, or an airplane, is a plane that is heavier than air which its appointment is generated by the difference in air pressure between the upper and lower wing surfaces. The Wright brothers, Wilbur and Orville Wright of Dayton, Ohio, made the first sustained and first sustainable aircraft flight under pilot control at Wright Flyer I on December 17, 1903 in Kitty Hawk, North Carolina. Within two years thereafter, they developed their glyphs into the first practical fixed wing aircraft in the world. In October 1905, Wright Flyer III was able and proven to rotate in the air 30 times in 39 minutes with a total distance of 24.5 miles. Your fundamental breakthrough is the discovery of "three-axis control", which allows the pilot to steer the aircraft effectively and maintain its balance. This required method has become standard on all fixed wing aircraft. From the beginning of their aeronautical work, the Wright brothers focused on unlocking control secrets to conquer "flying problems", rather than developing more powerful machines like some other experiments do. Charles Edward Taylor built the first aircraft engine and was an important contributor to the mechanical aspects of building and maintaining the early Wright engines and aircraft. Despite many previous attempts at heavier air-powered flight, some of which achieved a successful short jump, and denied previous claims of ongoing flights, the Wright brothers were officially credited by FÃÆ'Ã… © dà © ration AÃÆ'  © ronautique Internationale, the agency an international record for aeronautics and astronautics, as achieving "heavier, more controllable air-powered flight". In addition, the US patent number # 821393 for the plane, filed by Orville Wright on March 23, 1903 and issued in May 1906.

1903 wiper Windshield

The windshield wiper is a bladed device used to wipe rain and dirt from the windscreen. In 1903, Mary Anderson was credited with creating the first operational windshield eraser. In Anderson's patent, he called the invention of window cleaners for electric cars and other vehicles. Operated through a lever from the vehicle, the wiper version of the glass is very similar to the windshield wipers found in many early car models. Anderson has a design model that is produced. He subsequently filed for a patent (US patent number 743,801) on 18 June 1903 issued to him by the US Patent Office on 10 November 1903.

1903 gelas Wood

Glass wood is a light filter used in communications during World War I. The technique of "invisible radiation" that works well in infrared daytime communication and ultraviolet night communication, this glass does not emit visible light, leaving "invisible radiation" as a signal emission. Glass wood was invented by Robert Williams Wood in 1903.

1903 Wooden Lamps

Wood Lamp is a diagnostic tool used in dermatology that shines ultraviolet light to the patient's skin; a technician then observes the next fluorescence. Although the technique for producing ultraviolet light sources made by Robert Williams Wood in 1903 using "Wood's glass", it was not until 1925 was a technique used in dermatology by Margarot and Deveze to detect fungal infections in hair.

1903 Baler (round)

A baler is part of an agricultural machine used to condense cut and carded plants (such as straw, straw, or silage) into compact bales that are easy to handle, transport and store. Several different types of balers are commonly used, each producing different types of bales - rectangular or cylindrical (round), of any size, tied with thread, netting, or wire. The round straw baler was created by Ummo F. ​​Luebben of Sutton, Nebraska, whom he conceived with his brother Melchior in 1903, and then patented in 1910. The invention of the round baleric baller revolutionized the grueling task of straw into one man, cheap with a machine that automatically collects the straw, rolled into a round bale, and pulls it out.

1904 Automatic transmission

Automatic transmission is a car gearbox that changes the gear ratio automatically when the vehicle is moving, freeing the driver from having to manually move the gear. Modern automatic transmission tracks its origins to the early gearbox "horse-drawn carriages" developed in 1904 by Sturtevant's brothers from Boston, Massachusetts.

1904 Fractional banana

• A piece of banana is an ice cream dessert. In its classical form it is presented in a long dish called a boat. Bananas are cut in half lengthwise (because they are split) and placed on a plate. There are many variations, but the classic banana split is made with a scoop of vanilla, brown, and strawberry ice cream served in a row between separate bananas. Although bananas as an exotic fruit were introduced to the American public in the 1880s, then in 1904, that banana splits were discovered in the town of Latrobe, Pennsylvania by 23-year-old pharmaceutical apprentice David Strickler, who was inspired to make a new sundae after seeing a jerk soda during a visit Atlantic City. According to The Food Chronology , written in 1995 by James Trager, Strickler composed his sundae to include three spoons of ice cream on a divided banana, covered with chocolate syrup, marshmallows, beans, whipped cream, and the cherries are sold for a penny. Other soda growers soon mimic Strickler banana pieces, albeit in other forms.

1904 Pantograph (diamond shaped)

• Pantograf is a tool that collects electric current from the air ducts for electric trains or trams. This term comes from a resemblance to a pantograph device for copying writing and drawing. In 1904, a diamond-shaped pantographic roller was invented by John Q. Brown from Key System stores for their commuter train that runs between San Francisco and the East Bay section of the San Francisco Bay Area in California. The patent was issued on July 5, 1904.

Dragline 1904 Excavator

• The drag-line drilling system is a heavy equipment used in civil engineering and surface mining. In smaller type civil engineering is used for the construction of roads and ports. Larger types are used in strip mining operations to move overburden over coal, and for tar-sand mining. The drag-line bucket system consists of a large bucket hung from a boom, a structure like a large truss, with a wire rope. The bucket is maneuvering with a number of ropes and chains. The hoist strap, powered by large diesel or electric motors, supports bucket assemblies and hoist-couplers from the boom. The drag rope is used to draw the bucket assembly horizontally. With a skilled maneuver of hoists and ropes, the buckets are controlled for various operations. The dragline excavator was discovered in 1904 by John W. Page.

1905 Batting helm

The batting helmet is a protective head protector worn by batter in a baseball or softball game. This is meant to protect the batter head from the wrong pitches thrown by the pitcher. A dough that is "struck by a pitch", due to unintentional wild pitch or attempts aimed at the pitcher to hit it, may be serious, even fatal, hurt. In 1905, the New York Giants baseball player named Roger Bresnahan, after a thirty-day absence from the baseball season and lying in a hospital bed with a head injury (or beaning), was created, with the help of AJ Reach Company, rugged motorcycle helmet, leather, and sliced ​​vertically on top of his hat which is considered the first batting helmet. The headgear was unpopular, even with Bresnahan at the time, and it was not until the mid-1950s that his idea was accepted.

1905 Liquid ring pump

The liquid ring pump is a rotating positive displacement pump driven by an induction motor and is usually used as a vacuum pump or as a gas compressor. The liquid ring pump was invented in 1905 by Lewis H. Nash. Production soon begins thereafter at Nash Engineering Company. Nash filed US patent # 1,091,529 on February 24, 1910 and was issued to him on March 31, 1914.

1905 Ice pop

• An ice pop is a frozen water-based dessert on a stick. This is made by freezing colored fluids around the stick. Once the liquid solidifies solids, the stick can be used as a handle to withstand the ice pop. Ice pop was invented by the 11-year-old Frank Epperson in 1905. Living in San Francisco, Calif., Epperson had left fruit drinks overnight, with a stirrer in it, thus frozen him. In 1923, Epperson got a patent on "frozen ice on a stick". Epperson also found twin pop ice, with two sticks so that it could be shared by two children. The most famous brand name associated with ice pop is Popsicle .

Preparation of 1906

• Font settings are retrieved fonts and their order according to the language orthography for visual display. Typesetting was invented by John Raphael Rogers of Brooklyn, New York who filed a US patent # 837127 on October 8, 1906 and was issued to him on November 27, 1906.

1906 Flushometer

• Flushometer, or royal flushometer is a water pressure system that uses an inline grip to flush toilets and urinal. By using pressurized water directly from the supply line, there is a faster recycling time between flushes. Flushometers are still used today in homes and public toilets around the world. Flushometer was created in 1906 by American businessman and inventor William Elvis Sloan.

1906 Audion tube

• Audion is an electronic amplifier device and is the precursor of the triode, in which the current from the filament to the plate is controlled by a third element, the grid. A small amount of power applied to the grid can control larger currents from filaments to plates, allowing Audion to detect radio signals and to provide amplification. Audion Tubes invented by Lee De Forest in 1906.

1907 Curtain Rod

• The curtain rod or trunk is a tool used to suspend curtains, usually over a window or along the edge of the shower, although wherever the curtain might be used. Flat curtain rods and telescoping were discovered by Charles W. Kirsch of Sturgis, Michigan, in 1907. However, they were not used until the 1920s. Kirsch also invented the curtain rod trajectory in 1928.

1907 Electrostatic precipitator

• An electrostatic precipitator (ESP), or an electrostatic air purifier is a particle collection device that removes particles from a flowing gas (such as air) using an induced electrostatic charge force. Electrostatic precipitators are highly efficient filtration devices that minimally inhibit gas flow through the device, and can easily remove fine particles such as dust and smoke from airflow. In 1907, California physicist Frederick G. Cottrell invented and received a patent for electrostatic precipitators.

1907 Paper towel

• Paper towels have the same purpose as conventional towels such as hanging hands, wiping windows, cleaning dust, cleaning up spills. However, paper towels can only be used once after they remove the wet surface. A school teacher in Ashland, Ohio, named Kurt Klier, gives students individual paper boxes, so a single towel in the bathroom will not be infected with germs. When Arthur Scott, the head of Paper Company Scott heard about it, he decided to try to sell a lot of paper that had been made too thick to use as toilet paper.

1908 Apple candy

Candy apples, also known as toffee apples outside North America, are whole apples covered in a layer of hard candy. While toppings vary from one place to another, they are almost always served with wooden sticks in the middle making it easier to eat. Toffee apples are a common meal at autumn festivals in Western culture in the Northern Hemisphere, such as Halloween and Guy Fawkes Night because this festival falls after the annual harvest of apples. Dipping fruit into a sugar syrup is an ancient tradition. However, the origin of red candy apples is associated with Newark, a New Jersey candymaker containing the idea of ​​putting apples into a mixture of red cinnamon candies in hand. In addition, the apple dip in hot caramel was a 1950s American invention associated with a salesman of Kraft Dan Walker.

1909 Bola Skee

Skee ball is a common game found in the arcade and one of the first redemption games. The skee ball is similar to bowling except it is played on a sloping track and the player aims to make the ball fall into the hole rather than drop the pin. The purpose of the game is to collect as many points as possible by scrolling the ball onto a slope and into the hole points value specified. The skee ball was created and patented in 1909 by J.D. Estes of Philadelphia.

Paper shredders are used to cut paper into chad, usually in the form of strips or fine particles. Government organizations, businesses, and individuals use shredders to destroy personal, confidential, or other sensitive documents. The first paper shredder is credited to the prolific inventor Abbot Augustus Low of Horseshoe, New York. The patent is for "used paper containers" to offer a better method of disposing of waste paper receiving US patents on August 31, 1909.

1909 Presses

• The suppressor or silencer is a device attached or part of a firearm barrel to reduce the amount of noise and flash produced by firing a weapon. It generally takes the shape of a cylindrical metal tube with various internal mechanisms to reduce the sound of the shot by slowing the escaping propellant gas, and sometimes by reducing the velocity of the bullet. Hiram Percy Maxim, the son of the inventor of the famous machine gun Hiram Stevens Maxim, is credited with creating a suppressor in 1909.

1909 Gin remi

• Gin remi, or Gin for short, is a simple and popular two player card game with a standard 52 card package. Gin Rummy's goal is to score more points than the opponent fixes one's hands by forming a meld and removing dead wood. Gin rummy was invented by Elwood T. Baker and his son C. Graham Baker in 1909.

1910 Headset

• A headset is a headphone combined with a microphone. The headset provides an equivalent function of the phone handsets with hands-free operation. They are used in call centers and by people in telephone intensive jobs. The headset was first discovered in 1910, by a Stanford University student named Nathaniel Baldwin.

1911 Fifth wheel coupling

• The fifth-wheel-drive provides a rotating link between a semi-trailer and a towing truck, a tractor unit, a trailer or a prominent doll. Some recreational vehicles have a fifth-wheel configuration, which requires the clutch to be installed at the base of the pickup truck as a towing vehicle. The clutch consists of clutch pins (or padlocks) on the front of the semi-trailer, and a horseshoe-shaped clutch device called the fifth wheel behind the towing vehicle. In 1911, Charles Martin invented the fifth wheel-drive consisting of a round plate with a hole in it, attached to a frame mounted on his tractor.

1911 Erector Set

• Set Erector is a set of toy construction consisting of a collection of small metal beams with ordinary holes for nuts, bolts, screws, and mechanical components such as pulleys, gears, and small electric motors. Popular in the United States, the brand name is currently used for the Meccano set (itself patented in 1901). The erector set was invented in 1911 by Alfred Carlton Gilbert and produced by A. C. Gilbert Company at Erector Square factory in New Haven, Connecticut. The first set is called by A.C. Gilbert "The Erector/Structural Steel & Electro-Mechanical Builder". Accessory sets are also available to allow children to improve the basic set.

1911 Clip fastener

Clip binders or clip bank clips or foldback, is a simple device to bind the paper together. It leaves the paper intact and can be removed quickly and easily unlike staples. The binding clips were discovered in 1911 by Washington residents, D.C. Louis E. Baltzley is motivated by the desire to help his father, Edwin, a prolific writer and inventor, keep his manuscripts organized. The original design was modified five times, but the essential mechanism never changes.

1911 Self starter mobil

Automobile starter is an electric motor that initiates rotational motion in an internal combustion engine before it can turn on its own, thus removing the hand crank used to start the engine. In 1911, Charles F. Kettering created a self-starter car while working at the National Cash Register and then sold it to be installed on cars at the Cadillac company. There has been a lot of effort to produce an electric starter before, but nothing works. Most of the designs at the time called for the use of an electric motor attached to the engine's flywheel. However, in order to fit in the compartment of the car engine, the device must be small, and therefore will not be able to generate sufficient torque.

1911 Marking road surface

Marking the road surface is any type of device or material used on the road surface to convey official information for drivers and pedestrians. Edward N. Hines began the concept of painting a line in the middle of the road to separate traffic in the opposite direction. They were first used in Wayne County, Michigan in 1911.

1912 Autopilot

An autopilot is a mechanical, electrical, or hydraulic system used to guide a vehicle without human help. Most people understand autopilot to refer specifically to aircraft, but automatic steering devices for ships, boats, spacecraft, and missiles are sometimes also called autopilot . The first autopilot aircraft was invented by Lawrence Sperry in 1912. Sperry showed it in 1914, and proved the credibility of this discovery by flying the plane with his hands away from the control and visible to the audience.

1912 Electric blanket

The electric blanket is a blanket with an integrated electric heating device that is usually placed on top of the top bunk bed. The first electric blanket was invented in 1912 by American doctor Sidney I. Russell. The earliest form of this electric blanket is 'underblanket' under a closed bed and heated from below. In 1937, electric overblankets located above the sleeping person were introduced in the United States.

1912 Traffic light (electric)

Traffic lights, also known as traffic signals, are signaling devices located at crossroads, pedestrian crossings, or other locations. The goal is to show, use a series of colors, the right moment to stop, drive, ride or walk, using a universal color code. The color of the traffic lights representing stop and go may come from the one used to identify the port (red) and right (green) in the maritime rules governing the right of the road, where the ship on the left should stop for one intersection on the right.. In Salt Lake City, Utah, Lester Wire police found the first red-green electric traffic light.

1913 Formica (plastik)

Formica is a durable laminated plastic used for countertops, cabinet doors, and other surfaces that are heat resistant and easy to clean. Formica was discovered in 1913 by Herbert A Faber and Daniel J. O'Connor of Westinghouse Electric.

1914 Regenerative circuit

The regenerative circuit allows electronic signals to be reinforced many times by the same vacuum tube or other active components such as field effect transistors. The regenerative circuit is often an AM detector, converting the RF signal to the antenna into an audio waveform. The use of their positive feedback greatly improves the selectivity and sensitivity of simple receivers. Positive feedback builds the input signal to a very high level. Edwin Armstrong, discovered and patented the regenerative circuit when he was a junior at college, in 1914.

1914 Traffic cone

• Traffic cones, also called toddlers, road cones, safety cones, construction cones, pylons, or Witch Hats, are usually conical markers placed on roads or sidewalks to temporarily divert traffic in a safe way. Traffic cones were discovered in 1914 by Charles P. Rudabaker.

1914 Cookie of luck

• The lucky cake is a pastry usually made from flour, sugar, vanilla, and oil with "luck" wrapped in it. "Luck" is a piece of paper with words of false wisdom or vague prophecy. In the United States, it is usually served with Chinese food in a Chinese restaurant as a dessert. The messages in it can also include a list of Chinese luck numbers and phrases with translations. Contrary to belief, the fortune cookie associated as a Chinese invention is a mistake. In 1914, the Japanese-American Makoto Hagiwara of the Japanese Tea Garden in San Francisco, California, introduced a fortune cookie and was therefore recognized as the discoverer.

1915 Skeet shooting

• Skeet shooting is an Olympic sport where participants attempt to crack clay plates that are thrown into the air at high speed from various angles. Firearms of choice for this task are usually of high quality, double-barreled above and below the rifle with 28/30 inch barrels and choked open. This event is partly intended to simulate the action of bird hunting. The shooter shoots from eight positions on a semi-circle with a radius of 21 meters (19 m), and position 8 between stations 1 and 7. There are two houses holding a device known as a "trap" that launches a target, one at each half-circle. The Skeet shooting began in Andover, Massachusetts in 1915, when Charles Davis's grouse hunter discovered a game he called "shooting all the time" to improve his wings.

1915 Single-sideband modulation

• Single-sideband modulation (SSB) is a more efficient amplitude modulation using power and bandwidth. Single-sideband modulation generates a modulated output signal that has bandwidth identical to the original baseband signal, unlike amplitude modulation which has twice the bandwidth. Although John Renshaw Carson invented the SBB in 1915, his patent was not granted until March 27, 1923.

1916 Hamburger Bread

• The hamburger bun is a horizontally sliced ​​roll of hamburgers, usually a patty consisting of ground meat that also usually contains lettuce, bacon, tomatoes, onions, pickles, cheese and spices such as mustard, mayonaise, tomato sauce and enjoy. The hamburger bun was discovered in 1916 by a fried cook named Walter Anderson, who founded White Castle in 1921.

1916 Lincoln Log

• Lincoln Logs is the name of a children's toy consisting of mini logs, used to build miniature forts, cabins and buildings. Lincoln Log was created in 1916 by John L. Wright, son of the famous American architect, Frank Lloyd Wright.

Supermarket 1916

Supermarkets are supermarkets that offer a wide range of food and household merchandise, which are organized into departments. The size is larger and has a wider selection than the traditional grocery store. The self-service supermarket concept was created by American businessman Clarence Saunders and his Piggly Wiggly store. Previously, customers would shop at a general store where the clerk behind the counter would take a limited supply in order for customers to buy. With new innovations from self-service Saunders, customers will be able to choose a wider selection of goods at competitive prices. Saunders first store opened in Memphis, Tennessee, in 1916.

1916 Cloverleaf Exchange

The cloverleaf exchange is a two-tiered intersection where the left turn, in the countries driving on the right, is handled by the winding streets. To get to the left, in right traffic, the vehicle first passes above or below another road, then turn right into a one-way three-quarter loop (270 Â °) and join the crossroads. The clover leaf was first patented in the United States by Arthur Hale, a civil engineer in Maryland, on February 29, 1916.

1916 Crane Truck

• Crane trucks are vehicles used to transport motor vehicles to other locations, generally repair garages, or to recover vehicles that are no longer on the surface of the passable. Vehicles are often withdrawn in case of damage or collision, or can be seized for legal reasons. The tow truck was discovered in 1916 by Ernest Holmes, Sr., of Chattanooga, Tennessee. He was a garage worker inspired to create inventions after he was forced to pull a car out of a tributary using blocks, ropes, and six people. The enhanced design leads him to produce wreckers.

Condenser 1916 Microphone

• Condenser microphones, also called capacitor microphones or electrostatic microphones, are microphones that contain capacitors that have two plates with a voltage between them. In a condenser microphone, one of these plates is made of a very lightweight material and acts as a diaphragm. The diaphragm vibrates when struck by sound waves, changing the distance between two plates and therefore changing the capacitance. Specifically, as the plates get closer, an increase in capacitance and charge current occur. When the plates are separated further, the capacitance decreases and the discharge current occurs. Voltage is required across the capacitor for this to work. This voltage is provided either by the battery in the mic or by external phantom power. Condenser microphones were invented in 1916 at Bell Laboratories by Edward Christopher 'E.C.' Wente, which becomes possible with the emergence of a vacuum tube (valve) to act as a low signal output amplifier.

1916 Light button (switch)

The toggle lamp switch is a switch, most commonly used to operate electric lights, permanently connected equipment, or electrical outlets where switch switches do not control the contacts directly, but through intermediate settings of springs and internal levers. The toggle light switch is safe, reliable, and resistant
