Abstract

1,222,584. Typewriters. H. P. A. SALAM. 24 April, 1969 [24 April, 1968], No. 19404/68. Heading B6F. [Also in Division H4] To ensure that a typewriter carriage 23 moves at a constant speed when a tabulator key 42 is depressed, a centrifugal friction governor 20 is coupled by way of a pinion 21 with a rack 22 moving with the carriage. As shown the tabulator key is depressed and pinion 21 engages rack 22, frame 44 being pivoted at 45 to the typewriter frame 46. Type bars or a type globe may be employed.
