1,247,840. Change-speed control. DAIMLERBENZ A.G. 8 Sept., 1970 [12 Sept., 1969], No. 42971/70. Heading F2D. In a sports-car change-speed gear shift mechanism in which a manual shift lever 2 is moved in a four-channel H-type gate to slide and turn a rod 1 for gear selection and establishment respectively, for five forward speeds and reverse, a spring or gravity-loaded latch pin 4 for preventing unintentional movement of the gear-shift lever 2 into the first or reverse speed gate channels 1, R, is released from the end of a groove 5 in the turn-and-slide rod 1 by an electromagnet 6 energized by a press-button switch 7 on the gear lever 2 whereby first or reverse speed may then be selected. The shift lever 2 moves in a four-channel shift pattern, two channels of which freely select the second to fifth ratios of the C.S.G., whilst the third and fourth offset channels separately select first and reverse ratios respectively. The axial width of the groove 5 in the turn-and-slide rod 1 corresponds to the distance between the two channels for the 2nd and 3rd and the 4th and 5th gear ratios respectively. |
