Title: Adjusting mechanism for variable speed gears more particularly for motor vehicles
IPC: B60W30/18
Filed: 1933-04-03
Abstract: 422,183. Controlling change speed gearing. JANIK, E., 5, Weimarerstrasse, Vienna. April 3, 1933, Nos. 10008 and 10009. Void [Abridged as open to inspection under Sect. 91 of the Acts, Oct. 5, 1933]. [Class 80 (ii)] Change-speed gearing of the sliding-gear or of the sliding-clutch type is controlled by turning a shaft 43, Fig. 2, stepwise by successive depressions of pedals 40, 90, the former for changing up and the latter for changing down. Depression of the pedal 40 first disengages the engine clutch, not shown, of a vehicle and then brings a mutilated rack a into engagement with a ratchet 100 on the shaft 43 so as to turn the shaft 43 clockwise. Successive depressions turn the shaft 43 farther and farther in steps. Depression of the pedal 90 first by a pin m and cam n depresses the pedal 40 far enough to open the engine clutch and then brings a rack b into engagement with a ratchet 200 to turn the shaft 43 one step at a time anticlockwise. In Fig. 3, is shown a notched wheel 20 fast on the gear-changing shaft 43 which co-operates with a spring detent 99 so as to arrest the gear-changing in passing through neutral to allow gears to spin freely and come to nearly equal speeds before engagement. An arrangement comprising three discs such as 11, Fig. 8, for operating selectively three shift rods such as 12<b> is indicated in the drawings, but the description depends for its sufficiency upon a reference to U.S.A. Specification 1,828,606 which is similar to British Specification 364,274. The arrangement shown in Figs. 8 and 9 suffices to move the shift rod 12b from neutral to two end gear positions. A tappet 16 on the disc 11 engaging a recess 18 in a fork end on the rod moves the rod one step right. Continued clockwise turning of the disc 11 then by other tappets 17, 22, 24, and notches 23, 19, 25, moves the rod two steps left, then two steps right, and so on.
