Abstract

653,230. Locking vehicle wheels. GENERAL MOTORS CORPORATION. Dec. 2, 1948, No. 31192. Convention date, Dec. 11, 1947. [Class 103 (i)] [Also in Groups XXIV and XXIX] A steering-column-mounted gear shift lever 250, Fig. 20, which can be rotated about the axis of the steering-column of a vehicle to move a change-speed selector-valve (see Group XXIV), into one of four operative positions through a concentric tube 258, linked lever 264 and a rock-shaft 173, Fig. 15, can also be rotated into a fifth (parking) position, reached only by first raising the lever to release a stoppin 253, Fig. 20, in which it takes up a lostmotion connection and straightens a spring- returned toggle 177, Fig. 15, advancing a single-toothed arm 171 into engagement with a toothed wheel 170, fast on the output shaft 60 of the change-speed gear to lock the vehicle positively against movement.
