eration of these pins and T-lever is thesame as in my previous patents where thetype-wheel or pad is shifted. With a type-wheel constructed in three sec-tions there will be three openings between thesaid sections, but the types may be close tothe edges of these sections so as to be equi-distant when the type-wheel is expanded. The wheels are to be placed so that thesleeves may be shifted when a blank space isover the impression-pad, so that an impres-sion will not be made when the sleeves areshifted by the upward movement of the print-ing-lever. I claim as my invention— The type-wheels, each divided into sectionsand connected to the disk e, in combinationwith the sliding sleeves i % for expanding thewheel, or allowing of its being contracted, forthe purposes, and substantially as set forth.

N. PETERS. Photo-Lithographer, Washington. D. C. United States Patent Office. THOMAS A. EDISON, OF NEWARK, NEW JERSEY, ASSIGNOR TO GOLD ANDSTOCK TELEGRAM COMPANY, OF NEW YORK CITY. IMPROVEMENT IN PRINTING-TELEGRAPHS. Specification forming part of Letters Patent No. 126,530, dated May 7,1872. To all whom U may concern: Be it known that I, Thomas A. Edison, ofNewark, in the county of Essex and State ofNew Jersey, have invented and made a newand useful Improvement in Printing - Tele-graphs; and the following is declared to be afull and correct description of the same. My present invention consists of a printiug-telegraph instrument in which the type-wheelis revolved and the printing and feeding mech-anism operated by a movement communicatedfrom the same armature of an electro-magnet.I make use of a type-wheel revolved by a step-by-step movement derived from the vibrationof t he armature of an electro-magnet, and be-tween lateral arms from the cores of said elec-tro magnet is a swinging p
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.
