Abstract

770,243. Communicating with the blind. NATIONAL INSTITUTE FOR THE DEAF. April 5, 1955, No. 9987/55. Addition to 741,288. Class 146(2). [Also in Group XVI] A device for communicating and conversing with the deaf-blind as claimed in the parent Specification has as the mechanical means a number of key-levers 23 pivoted on a common rod 25, a number of balls 34 located in six channels 33 disposed transversely of the keylevers, and a bell crank 43 associated with each of said channels 33 and in contact with the end ball therein, the bell cranks having plungers 44 to represent the six points of the Braille character. The key-levers 23 are selectively formed on their undersides with one or more projections, which, upon the depression of a key enter a space between the balls to cause the end ones to pivot the respective cranks 43 and raise the plungers 44 to form the character on a touching surface. A rubber covered U-shaped bar 18 serves as a rest for the machine and as a handle for carrying. The Braille characters may be formed in a paper strip for sending through the post (see Group XVI).
