Query: Who invented the telegraph machine?
Samuel Morse independently developed and patented a recording electric telegraph in 1837. Morse's assistant Alfred Vail developed an instrument that was called the register for recording the received messages. It embossed dots and dashes on a moving paper tape by a stylus which was operated by an electromagnet.[19] Morse and Vail developed the Morse code signalling alphabet. The first telegram in the United States was sent by Morse on 11 January 1838, across two miles (3km) of wire at Speedwell Ironworks near Morristown, New Jersey, although it was only later, in 1844, that he sent the message "WHAT HATH GOD WROUGHT" over the 44 miles (71km) from the Capitol in Washington to the old Mt. Clare Depot in Baltimore.[20][21]
By 1907, discontent was widespread among telegraphers. As in earlier strikes, the major issues were low pay, long working hours, and poor working conditions, as well as the telegraph companies' use of the "sliding scale," in which an operator who accepted a promotion or new position would be given a lower salary than the person who previously held that position. Another issue was the cost of providing a typewriter; as the use of the typewriter to copy messages became commonplace during the 1890s, employers required telegraphers to purchase their own machine.
In 1849, he learned about electricity, through the book of the Dutch scientist Van den Bergh, and created Japan's first telegraph, five years before the gift of such a telegraph by Commodore Perry in 1854. He also invented electric machines derived from the Elekiter.
In 1778, he invented a telegraph with which he was able to correspond with his friend Fortin de Bagneux, and must be considered among the first inventors of the telegraph that was perfected by Claude Chappe. The Revolution made it necessary to destroy his machine in order to avoid suspicion.
Before the invention of the radio, electronic media coverage of tropical cyclone was limited to the telegraph which was invented in 1839. A notable example of the telegraph coverage of tropical cyclones was during the 1900 Galveston Hurricane
In 1887 Gray invented the telautograph, a device that could remotely transmit handwriting through telegraph systems. Gray was granted several patents for these pioneer fax machines, and the Gray National Telautograph Company was chartered in 1888 and continued in business as The Telautograph Corporation for many years; after a series of mergers it was finally absorbed by Xerox in the 1990s. Gray's telautograph machines were used by banks for signing documents at a distance and by the military for sending written commands during gun tests when the deafening noise from the guns made spoken orders on the telephone impractical. The machines were also used at train stations for schedule changes.
William James Morrison (1860–1926) was an American dentist and inventor who is best known for developing the cotton candy machine.
Morrison, from Nashville, Tennessee, was an avid inventor, and has a number of inventions to his credit. One of them is the first [cotton candy] (originally named Fairy Floss and named Candy Floss in the UK and Fairy Floss in Australia) machine, which he invented in 1897 in cooperation with confectioner John C. Wharton. This electric machine melted sugar and then used forced-air to push it through a wire screen. It was introduced at the 1904 St. Louis World's Fair, and was a big success. Thomas Patton and Josef Delarose Lascaux also claimed to invent the cotton candy machine.
For its first use in combat, during the 1862 Peninsula Campaign, the Rogers train substituted a new telegraph instrument, the Beardslee Patent Magneto-Electric Field Telegraph Machine, invented by George W. Beardslee of New York. This instrument required no battery, using instead a hand-cranked generator, but it was also based on a dial indicator. The Beardslee telegraph was housed in a wooden chest with handles and weighed about 100 pounds. It had two significant technical deficiencies, however. Its generator could not produce enough electricity to transmit signals more than about 5 to 8 miles. More seriously, there was a tendency for the sending and receiving index pointers to get out of synchronization, hopelessly garbling transmitted messages. Broken machines had to be sent back to New York City for repair. It was these deficiencies that led Myer to his decision to use traditional Morse key technology and attempt to hire trained telegraphers, a decision that led Secretary Stanton to dismiss him as chief signal officer. All of the telegraph train assets of the Signal Corps were turned over to the Military Telegraph Service, but they did not use the Beardslee telegraph due to its unreliability. At their peak of usage in 1863, there were 30 telegraph trains in the field.
A major U.S. contribution to industrialization was the development of techniques to make interchangeable parts from metal. Precision metal machining techniques were developed by the U.S. Department of War to make interchangeable parts for small firearms. The development work took place at the Federal Arsenals at Springfield Armory and Harpers Ferry Armory. Techniques for precision machining using machine tools included using fixtures to hold the parts in proper position, jigs to guide the cutting tools and precision blocks and gauges to measure the accuracy. The milling machine, a fundamental machine tool, is believed to have been invented by Eli Whitney, who was a government contractor who built firearms as part of this program. Another important invention was the Blanchard lathe, invented by Thomas Blanchard. The Blanchard lathe, or pattern tracing lathe, was actually a shaper that could produce copies of wooden gun stocks. The use of machinery and the techniques for producing standardized and interchangeable parts became known as the American system of manufacturing.
In 1970, Wayne R. Moore wrote about the Moore family firm, the Moore Special Tool Company, who independently invented the jig borer (contemporaneously with its Swiss invention). Moore's monograph, "Foundations of Mechanical Accuracy", is a seminal classic of the principles of machine tool design and construction that yield the highest possible accuracy and precision in machine tools (second only to that of metrological machines). The Moore firm epitomized the art and science of the tool and die maker.
Although telegraphic printing systems were first invented by Royal Earl House in 1846, early models were fragile, required hand-cranked power, frequently went out of synchronization between sender and receiver, and did not become popular in widespread commercial use. David E. Hughes improved the printing telegraph design with clockwork weight power in 1856, and his design was further improved and became viable for commercial use when George M. Phelps devised a resynchronization system in 1858. The first stock price ticker system using a telegraphic printer was invented by Edward A. Calahan in 1863; he unveiled his device in New York City on November 15, 1867. Early versions of stock tickers provided the first mechanical means of conveying stock prices ("quotes"), over a long distance over telegraph wiring. In its infancy, the ticker used the same symbols as Morse code as a medium for conveying messages. One of the earliest practical stock ticker machines, the Universal Stock Ticker developed by Thomas Edison in 1869, used alphanumeric characters with a printing speed of approximately one character per second.
The Kleinschmidt keyboard perforator was first invented and constructed by Kleinschmidt in 1911. Kleinschmidt wanted to develop a product that could be sold to telegraph companies rather than just selling patents. Western Union Telegraph Company was the first to purchase 50 units. As a result of this order, the Kleinschmidt Electric Company was formed to manufacture the perforator. F. G. Creed ordered ten machines for Creed high-speed Continental-Morse-code system. The British Post Office ordered 20, and then later in 1914 ordered another 100. Later the Teletype Corporation also made this machine.
Electrical engineering became a profession in the late 19th century. Practitioners had created a global electric telegraph network and the first electrical engineering institutions to support the new discipline were founded in the UK and USA. Although it is impossible to precisely pinpoint a first electrical engineer, Francis Ronalds stands ahead of the field, who created the first working electric telegraph system in 1816 and documented his vision of how the world could be transformed by electricity. Over 50 years later, he joined the new Society of Telegraph Engineers (soon to be renamed the Institution of Electrical Engineers) where he was regarded by other members as the first of their cohort. The donation of his extensive electrical library was a considerable boon for the fledgling Society.
Development of the scientific basis for electrical engineering, with the tools of modern research techniques, intensified during the 19th century. Notable developments early in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, Michael Faraday, the discoverer of electromagnetic induction in 1831. In the 1830s, Georg Ohm also constructed an early electrostatic machine. The homopolar generator was developed first by Michael Faraday during his memorable experiments in 1831. It was the beginning of modern dynamos — that is, electrical generators which operate using a magnetic field. The invention of the industrial generator, which didn't need external magnetic power in 1866 by Werner von Siemens made a large series of other inventions in the wake possible.
The Wheatstone system was an automated telegraph system that replaced a human operator with machines capable of sending and recording Morse code at a consistent fast rate. The system included a perforator, which prepared punched paper tape called a Wheatstone slip, a transmitter that read the tape and converted the symbols into dots and dashes encoded as mark and space electric currents on the telegraph line, and a receiver at the other end of the telegraph line that printed the Morse symbols. The system was invented by Charles Wheatstone. Enhancements could be made so that it was a duplex system, able to send and receive on the same line simultaneously.
The Globotype is a colour display for telecommunications. It was invented and patented by David McCallum of Stonehouse, Devon, England. The device features very low cost and does not use consumable supplies. It is Royal Letters Patent No. 2924 issued December 29, 1855. The design and coding used is described in "Froehlich/Kent Encyclopedia of Telecommunications", Volume 2, pages 461 and 462. Mr. McCallum invented the Globotype in response to the use of printing telegraph machines which he saw as both expensive and unneeded.
In 1836 Elderton, David Alter invented the electric telegraph, one year before the popular Morse telegraph was invented. David rigged the telegraph between his house and his barn. He was interviewed about the discovery going unobserved by other inventors and said: "I may say that there is no connection at all between the telegraph of Morse and others and that of myself...Professor Morse most probably never heard of me or my Elderton telegraph."
In 1870 financing for Gray & Barton Co. was arranged by General Anson Stager, a superintendent of the Western Union Telegraph Company. Stager became an active partner in Gray & Barton Co. and remained on the board of directors. The company moved to Chicago near Highland Park. Gray later gave up his administrative position as chief engineer to focus on inventions that could benefit the telegraph industry. Gray's inventions and patent costs were financed by a dentist, Dr. Samuel S. White of Philadelphia, who had made a fortune producing porcelain teeth. White wanted Gray to focus on the acoustic telegraph which promised huge profits instead of what appeared to be unpromising competing inventions such as the telephone, White made the decision in 1876 to redirect Gray's interest in the telephone.
In 1865 Gray invented a self-adjusting telegraph relay that automatically adapted to varying insulation of the telegraph line. In 1867 Gray received a patent for the invention, the first of more than seventy.
Munson later went to work perfecting a typesetting machine that he had invented, which, being operated by means of a prepared ribbon of paper, automatically set a column of corrected, justified, and leaded type. He also invented the machines by which the ribbon is prepared, and a telegraph, also operated by the same paper ribbon, which causes an exact facsimile of the ribbon to be automatically produced at a distant point, ready for use in operating a similar typesetting machine. These inventions were based on his “Selecting Device,” which he also patented.
In 1843, Scottish inventor Alexander Bain invented a device that could be considered the first facsimile machine. He called his invention a "recording telegraph". Bain's telegraph was able to transmit images by electrical wires. Frederick Bakewell made several improvements on Bain's design and demonstrated a telefax machine. In 1855, an Italian abbot, Giovanni Caselli, also created an electric telegraph that could transmit images. Caselli called his invention "Pantelegraph". Pantelegraph was successfully tested and approved for a telegraph line between Paris and Lyon.
Edison presented his own account of inventing the phonograph. "I was experimenting," he said, "on an automatic method of recording telegraph messages on a disk of paper laid on a revolving platen, exactly the same as the disk talking-machine of to-day. The platen had a spiral groove on its surface, like the disk. Over this was placed a circular disk of paper; an electromagnet with the embossing point connected to an arm traveled over the disk; and any signals given through the magnets were embossed on the disk of paper. If this disc was removed from the machine and put on a similar machine provided with a contact point, the embossed record would cause the signals to be repeated into another wire. The ordinary speed of telegraphic signals is thirty-five to forty words a minute; but with this machine several hundred words were possible."
The invention of the electrical telegraph came under the control of the Telegraph Act 1869 which was based upon a law that forbade the encoding of electrical cables with messages without a licence. The messages were viewed as electrical forms of a letter. This invention was followed by the wireless telegraph which was then placed under the Wireless Telegraphy Act 1904.
In addition to the telegraph, Morse invented a marble-cutting machine that could carve three-dimensional sculptures in marble or stone. He could not patent it, however, because of an existing 1820 Thomas Blanchard design.
The Cooke and Wheatstone telegraph was an early electrical telegraph system dating from the 1830s invented by English inventor William Fothergill Cooke and English scientist Charles Wheatstone. It was the first telegraph system to be put into commercial service. The receiver consisted of a number of needles which could be moved by electromagnetic coils to point to letters on a board. This feature was liked by early users who were unwilling to learn codes, and employers who did not want to invest in staff training.
Stock ticker machines are an ancestor of the modern computer printer, being one of the first applications of transmitting text over a wire to a printing device, based on the printing telegraph. This used the technology of the then-recently invented telegraph machines, with the advantage that the output was readable text, instead of the dots and dashes of Morse code. A special typewriter designed for operation over telegraph wires was used at the opposite end of the telegraph wire connection to the ticker machine. Text typed on the typewriter was displayed on the ticker machine at the opposite end of the connection.
