Abstract
997,235. Screw-and-nut gearing. PARAMATIC DEVELOPMENT Ltd. Jan. 18, 1963 [Jan. 19, 1962: July 7, 1962], Nos. 1994/62 and 26136/62. Heading F2Q. [Also in Divisions B3 and G3] Backlash in a screw-and-nut gear 12, 20 driven by a motor 30 and gears 31, 31a is offset by springs 32 in the composite gear 31, auxiliary nuts 25, 26 spring-pressed against the screw, and by a spring acting against one of the end ball-bearings 34 of the screw.
