ed to the printing-leverand these springs take against flanges 6 uponthe respective type-wheels e d, and the wheelwhich is loose* upon the shaft is kept up bythe spring t in the position shown in Figs. 1and 2, so that the lower portion of the wheelis higher than the lower portion of the otherwheel, and cannot make an impression uponthe paper. A spring-finger, v, is employed tokeep the strip of paper in contact with theimpression-pad w and prevent blurring. I claim as my invention— 1.

N. PETERS. Photo-Lithographer, Washington. 0. C. 126,529 United States Patent Office, THOMAS A. EDISON, OF NEWABK, NEW JEESEY, ASSIGNOE TO GOLD ANDSTOCK TELEGEAPH COMPANY, OF NEW YOEK CITY. IMPROVEMENT IN TYPE-WHEELS FOR PRINTING-TELEGRAPHS. Specification forming part of Letters Patent No. 126,529, dated May 7, 1872. To all whom it may concern: Be it known that I, Thomas A. Edison, ofNewark, in the county of Essex and State ofNew Jersey, have invented and made an Im-provement in Printing-Telegraphs; and thefollowing is declared to be a full and correctdescription of the same. In Letters Patent heretofore granted to meprinting-telegraph instruments are. shown withtwo type-wheels upon a revolving shaft andfitted so that either of them may be printedfrom without impressing from the other type-wheel—shifting type-wheels and shields are em-ployed for this purpose. My present invention is to accomplish thesame object by the use of different means. Iemploy two type-wheels, each divided rad
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.
