Abstract

488,002. Handle-bar control mechanism. BRAUMANDL, K. M. Nov. 15, 1937, No. 31391. Convention date, Nov. 14, 1936. [Class 136 (i)] In twist - grip mechanism for controlling change-speed gears or other devices on motor and other cycles &c., the rotatable grip or sleeve 3 is provided with a plain cam track 7 engaged by a projection 5 on the end of the transmission cable &c. 6, and is retained in any required position by means of a fixed notched ring 13, one of the notches 8 in which is engaged by a projection 14 on the sleeve 3, which is forced towards the ring 13 by a spring 10. The sleeve 3 is mounted on a fixed sleeve 2, secured to the end of the handlebar 1 and provided with a longitudinal guide slot for a slide 4 carrying the projection 5, the slide 4 being secured to the cable 6. The spring 10 abuts against an end collar 15, and the ring 13 is carried by a collar 12. The rotary grip may be provided with a position-indicating device, and may control a number of devices by being provided with a number of cam tracks and slides. The Specification as open to inspection under Sect. 91 comprises also a construction in which the notched retaining-ring and coacting projection are omitted, notches being formed in the cam track itself. This subject-matter does not appear in the Specification as accepted.
