Abstract

1291787 Change-speed control FORD MOTOR CO Ltd 1 Jan 1971 21/71 Heading F2D A manually operated steering column gear shift lever and rod 30, 36 is connected to a turn- and-slide gear selector rod 14<SP>1</SP> of a motorvehicle C.S.G. by a slotted bell-crank lever 42 pivotably and slidably mounted on a fixed pin 46 on a gear-box casing 10<SP>1</SP>, the rod 36 being rigidly fast with an arm 38 the end of which is connected by a ball joint to the lever 42 whereby axial movement of the lever 30 along the steering column axis, i.e. path 52, axially moves the rod 36 to pivot the lever 42 at pin 46 to turn the rod 14<SP>1</SP> for gear selection (Fig. 4), whilst transverse movement of the lever. 30 along path 34 turns the rod 36 and thus causes the lever 42 to rock and slide via the slot 44 about the pin 46 and axially slide the rod 14<SP>1</SP> for gear establishment, the direction, i.e. angle, of the slot 44 offsetting the rocking movement to produce a purely axial sliding movement of the rod 14 (Fig. 5). The lever 42 may alternatively have a pin engaging a correspondingly arranged slot in the gear casing or, alternatively, the pin and slot may be replaced by a member 54 (Fig. 3) pivotally connected at 56, 58 to the gear-box 10<SP>1</SP> with the lever 42 connected by a ball joint 50 to the member 54, the arrangement functioning in a similar manner to the pin and slot connection described above.
