Abstract
260,409. Fletcher, S. R. Oct. 8, 1925. Controlling variablespeed gearing.-A hand or foot lever, particularly for operating the change-speed gear of a motor cycle, is fitted with an arrangement of detents which ensure its step-by-step movement. A handle 17 pivoted to the lever 10 is normally kept centralized by a spring- pressed plunger 19 and carries a pivoted detent 26 adapted to engage abutments 13 - - 16 on an arc-shaped guide 12. The first movement of the handle depresses the detent and continued movement shifts the lever until the detent meets an abutment 14; on releasing the handle the detent clears the abutment 14 and comes into position to engage the abutment 15 on the next operation. 'A spring or gravity actuated detent 22, which may be carried by the plunger 19, or may be separately operated by a grip lever, engages notches in the guide 12 to hold the lever in the required positions. A second detent 27 may be provided to co-operate with another guide 12 for controlling movement of the lever in the opposite direction. Instead of being pivoted the detents 26, 27 may be rigid with a cross-piece 25 on the handle.
