he type-wheel will move sixletters or spaces, and complete a revolution ineither four or five pulsations of the magnet u,according to the number of characters uponsuch type-wheels. In this manner great rapid-ity can be obtained, because the long intervalsand numerous pulsations required between im-pressing one letter and the next are lessened.The magnet u may be energized by a reversalof the current operating in the magnet e, orby a separate line-wire. The transmittingdial or instrument may be of any desired char-acter adapted to these two magnets, and thecurrents to them. I claim as my invention— A type-wheel in combination with two ac-tuating magnets and connections, substantial-ly as set forth, one for operating a step-by-step motion one letter or division at a time,and the other for moving the type-wheel twoor more letters or divisions at a time, substan-tially as specified. Signed by me this 26th day of April, A. D.1872. T. A. EDISON. Witnesses: Geo. T. Pinckney,Ohas. H. Smith.

N. PETERS.-Photo-Lithographer, Washington, D. C. 138,607 United States Patent Office. THOMAS A. EDISON, OF NEWAB&, NEW JERSEY.IMPROVEMENT IN PRINTING-TELEGRAPHS. Specification forming part of Letters To all wTiom it may concern: Be it known that I, Thomas A. Edison, ofNewark, in the county of Essex and State ofNew Jersey, have invented an Improvementin Printing-Telegraphs5 and the following isdeclared to be a correct description • of thesame. In this instrument the magnet that givesthe impression is in the main-line circuit aswell as the type-wheel magnet, but the formeris cut out by a shunt or short circuit thatis closed when the instrument is not working,and during the pulsations that set the type-wheel ; but when a pause occurs with the cir-cuit closed this short circuit is broken by agradually-operating spring or weight controlledby an air-cushion, so that the electricity isforced to pass through the printing-magnetand gives the impression, simply in conse-quence of keeping
Thomas Edison, 1847-1931, is credited with the development of many important inventions and technologies. Some of his most notable patents and inventions include: - The light bulb: Edison's most famous invention, the light bulb, revolutionized the way we light our homes and businesses. He worked for many years to perfect the design of the light bulb, and his efforts ultimately led to the development of a practical, long-lasting, and commercially viable electric light. - The phonograph: Edison's phonograph was the first device to successfully record and reproduce sound. The phonograph used a cylinder coated with a substance that could be etched by sound waves to record audio, and a needle to play it back. This invention paved the way for the development of the modern record player and other audio recording and playback technologies. - The motion picture camera: Edison's motion picture camera, also known as the kinetograph, was the first device to successfully capture moving images on film. The kinetograph used a series of rapidly rotating lenses to record a series of still images, which could then be played back in rapid succession to create the illusion of motion. This invention laid the foundation for the modern film industry. - The electric pen: Edison's electric pen was an early precursor to the modern-day tattoo machine. The device used a needle that was rapidly vibrated by an electric motor to create a series of punctures in a sheet of paper. This allowed users to easily create multiple copies of a document using a technique known as stenciling. - The electric vote recorder: Edison's electric vote recorder was an early voting machine that was designed to automate the process of tallying and recording votes in elections. The device used a series of levers that could be activated by voters to indicate their choices, and a mechanism to tally the results and display them on a dial. This invention was intended to improve the accuracy and efficiency of the electoral process.
