Title: Method of and means for electric control of tipping gear upon vehicles
IPC: B60P1/06
Filed: 1920-03-04
Abstract: 164,464. Smith, P. F., Dine, E. H., and Stocks, F. R. March 4, 1920. Switches, actuating; electric-motor actuation.- An electric control for the tipping mechanism of a vehicle automatically cuts off the current at extreme. positions of the tipping body and is reversible at intermediate positions. A lug 29, Fig. 4, on the nut 28 of a screw and sliding-nut tipping-mechanism co-operates with stops 22, 21, on a rod 1 to move the rod slightly forwards or backwards. A casing 3 sliding on the rod is movable rearwards by a lever near the driver's seat. In the casing 3, Fig. 1, is a switch comprising sliding contacts 5, 6, which are thrust into and out of contact -with fingers 8 - - 11 by a spring 7 and shoulders 32, 56 on the rod 1 respectively. Tipping is effected by moving the casing 3 rearwards, thus freeing the contact 5 since the lug 29 and stop 22 prevent the rod 1 from moving. This disconnects the inoperative side of a reversible switch (not shown) so that reversal of the motor is impossible. As the lug 29 moves, the spring 7 moves back the rod 1 and contact 5 so that reversal becomes possible. When the lug 29 nears the end of its travel it moves the stop 21, thereby freeing the contact 6 and disconnecting the operative side of the reversing switch so that the motor is stopped. During the return of the body to its normal position, the operation is reversed. Specification 163,792, [Class 108 (i), Road vehicles, Body details &c. of], is referred to.
