1,065,743. Change-speed control. CHRYSLER CORPORATION. Nov. 2, 1964 [Aug. 25, 1964], No. 44568/64. Heading F2D. In a four forward and one reverse manually controlled countershaft gear, an interlock between a lever 132, pivoted at 136 and actuating a reverse-idler shift-yoke (129), and a lever 96, pivoted at 98 and actuating a first-second speed shift-yoke (90), comprises complementary arcuate segments 184, 186 formed on the respective levers, which obstruct movement of the first-second speed lever 96 from neutral towards an operative setting when the reverse lever 132 is moved towards reverse setting. A further interlock between the 1-2 shift-lever 96 and a 3-4 shift-lever 86 comprises a drift-pin 112 between two balls 126 in a stationary cage between segmental portions of the shift-levers, the balls being also outwardly spring-loaded to engage notches 118 in the segmental portions to locate the shift levers in set positions. A spring-loaded ball-detent 160 similarly locates the reverse shift-lever 180. The three shiftlevers are externally linked to a manual lever 151. The change-speed gear, Fig. 1 (not shown), is of the conventional type in which the 3-4 lever 86 operates a synchromeshed double clutch, and the 1-2 lever 96 a clutch which is similar but carries external gear-teeth for meshing a slidable reverse idler operated by the reverse lever 132. |
