Abstract

350,376. Typewriters. WILKINSON, G. E., 50, Rue Carnot, Cormeilles-en-Parisis, Seine-et-Oise, France. March 29, 1930, No. 3724/31. Divided on 345,109. [Class 100 (iv).] Machines for coding; keys.-Key-caps for coding or decoding are each provided with removable discs bearing characters so arranged as to appear side-by-side. The cap 19 shown in Figs. 1 and 5 is formed with ribs 21, 22 for engaging the key 20, and a rib 23 for holding a rubber washer 25, an opaque disc 30, and transparent discs 31, 32, 33, the discs 30, 31, 32 bearing the characters a, J, and , respectively. The characters a, J, and , or corresponding code-characters are printed in the normal, shift, and double-shift positions of the platen. The keys may be divided into groups distinguished by character-discs of different colours. The groups may be employed for coding the characters represented by the key-caps and any key of a group may also be employed for coding a vowel or other character arbitrarily assigned to that group. Specification 345,109 is referred to.
