Abstract
406,755. Controlling change - speed gearing. RAOULT, R., 34, Rue Dartois, LiÞge, Belgium. Sept. 9, 1932, No. 25223. Convention date, Sept. 9, 1931. [Class 80 (ii).] Control mechanism for change-speed gearing upon motor cycles comprises a cam 3, Figs. 2 and 4, which disengages the engine clutch, not shown, at each speed change. The cam 3 is fast on a rock shaft 2 to which are also secured a control pedal 1 and a lever arm 9 connected by a push and pull rod 11 to the speed changing mechanism shown in Figs. 1 and 6. The cam 3 rocks between fixed plates 4 slotted for the passage up and down of a cross pin 6 which rests in a depression z in the cam. A slide 7 adapted to move up and down carries the pin 6 and is connected through a cable 8 to the engine-clutch disengager. The pin 6 in rising out of the depression z pulls up the cable 8. The pin 6 then rides over an arc x y on the cam while the pedal 1 is moving farther to effect the speed change. Successive oscillations of the pedal 1 upwards turn a gear-changing shaft 14 by successive steps clockwise, and successive depressions of the pedal 1 turn the shaft 14 the other way. The rod 11 connects to a segmental frame 13, Fig. 1, which rocks about the shaft 14 as a pivot and carries two pawls 15<a>, 15<b> which trail over the surface of a fixed guide 17. In the guide 17 are slots 17<a>, 17b, Fig. 6, under which are segmental blocks 18<a>, 18<b>, respectively, with oppositely-directed teeth q, r. The blocks 18<a>, 18b are fast on the shaft 14. On a depression of the pedal 1, the frame 13 rocks to the left of Fig. 1 until the pawl 15<a> drops through the slot 17<a>, and engages a tooth q. Continued movement carries the block 17<a> and shaft 14 to the left until the pawl strikes the end of the slot at m, Fig. 6, and is stopped thereby. A gear change has thus been effected and the shaft 14 is held by suitable means while the frame 13 and pedal 1 are returned to middle position by a spring, not shown.
