  • Patent number: 4079825
    Abstract: A portable typewriter for embossing paper or the like according to the Braille code system and other like systems. It consists generally of a base having a matrix of Braille cells, a vertical track which guides a horizontal track upon which a keyboard transverses. The keyboard has six keys as well as bars for tab setting, clearing, and by-passing and bars for spacing and keyboard return. The close spacing of the keys allows two or more keys to be depressed using one or more fingers. This bridging expedites typing speed.
