Typewriter

In 1843, the first U.S. design of a typewriter that successfully typed was issued a patent to Charles Thurber of Norwich, Conn. (No. 3,228) as a “machine for printing by hand by pressing upon keys which contain the type, called ‘Thurber's Patent Printer.’” He was the first to place the paper on a roller and give it longitudinal motion with provision for accurate letter and word spacing. It had a wheel carrying the keys around its circumference. A roller provided inking. However, the machine was slow to use, and only a concept model. Two years later, he patented a design for a writing (not typing) machine, which he called a Chirographer (18 Nov 1845, No. 4,271). On 27 Jun 1857, British Letters Patent were sealed (No. 1805) on Thurber's invention of “An improved caligraph.”«[Image: Thurber's Patent Printer of 1843.]
