t distance.I claim as my invention— 1. Perforations for dashes in telegraphictransmitting-paper composed of two small andan intermediate large perforation, as specified. 2. A perforating mechanism composed ofthree punches in combination with two keys,arranged substantially as specified, so that all 2 132, three punches will be actuated by one key andonly one by the other key, as set forth. 3. A feeding-roller actuated by a lever andpawl in combination with the perforating-punches and keys, and intervening mechanismfor regulating the movement of the lever inproportion to the length of feed-movementrequired for the paper. 4. The notched slide * in combination withthe lever p and keys for spacing the distance 456 between the perforations, substantially as setforth. 5. The finger x actuated by the key w incombination with the pawl n and paper-feed-ing lever p, substantially as set forth. Signed by me this 15th day of March, 1872. T. A. EDISOX. Witnesses: Geo. T.

IMPROVEMENT IN ELECTRICAL PRINTING-MACHINES. Specification forming part of Letters Patent No. 133,019, dated Norember 12,1872. 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 an Improvementin Electrical Printing-Machines; aud the fol-io wing- is declared to be a correct descriptionthereof. This invention is intended for printing- upona strip or sheet of paper by a type-wheel, sothat messages, instead of being written, canbe printed off by touching finger-keys. Themachine is also available for printing copiesof documents or composing and printing in-stead of writing. I make use of a type-wheel upon a shaft thatalso carries an, armature and circuit-breakerthat is driven by a magnetic motor, the saidarmatu

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.
