Henry Mill of England patented a typewriter in 1714. The firm of Sholes, Glidden & Soulé developed a practical machine in the U. S. in 1867, and typewriters began to be marketed by Remington in 1874. First U. S. patent on a writing-machine, however, was issued in 1829 to a remarkable man named William Austin Burt. On this device, in March 1830, Inventor Burt whacked out the first letter typewritten in the U.S. Last week the Smithsonian Institution proudly announced that it had acquired and would shortly display this message...
Inventor Burt's machine, made entirely of wood, was destroyed in the Patent Office fire of 1836. It was a ponderous gadget with the type carried on a circular frame operated by a lever.

Whiskers caught in these slots are cut off by a blade shuttling back and forth beneath them. The Lektro-Shaver differs by being roundheaded, with a single horizontal slot in which whiskers are sheared off by a blade in rocking motion. Dictograph held that these differences were essential and that the Schick patent had been anticipated, anyway, by an English inventor named Appleyard in 1913. The court, however, found the evidence...
Promptly Dictograph announced that it would appeal the decision, reminded dealers that patent insurance protected them against possible loss, found cause for satisfaction in the court's finding that a second patent dealing with hair disposal mechanism had not been infringed...
