Title: Means for actuating road vehicle direction indicators of the flashing type
Inventor: WHEATLEY DENIS
IPC: B60Q1/38
Filed: 1953-10-14
Abstract: 742,691. Road-traffic signals on vehicles. C.A.V., Ltd., Sept. 14, 1954 [Oct. 14, 1953], No. 28282/53. Class 118(2) Apparatus for actuating vehicle direction indicators of the flashing-light type comprises a motor-operated switch for controlling the lamp circuits, a two-position switch for controlling the motor, and an electromagnet-for actuating the motor-controlling switch provided with a pair of windings respectively arranged in parallel and in series with the motor-operated switch such that the motor-operated switch when in one of its positions short-circuits the parallel winding of the electromagnet, the circuit being so arranged that when signalling lamps are switched on the current passes through the series winding of the electromagnet thereby closing the motor circuit so that the parallel winding is alternately short-circuited and placed in series with the series winding, the reduced current through the two windings in series being insufficient to light the lamps but sufficient to maintain the electromagnet operated, keeping the motor, running and the lamps, therefore, flashing. In the Figure a and b are right-hand and left-hand signalling lamps respectively and when selector switch d is moved to either side the current from battery g to the selected lamps passes via contacts i, j and winding r which alttracts armature o to close contacts n, m and start the motor e, Cam f, driven by motor e, opens and closes contacts i, j, thereby intermittently placing winding s in series with winding r and the lamps, which are thereby caused to flash, but the reduced current when winding s is in circuit still holds contacts n and m closed. The contacts i, j are effectively bridged-by yoke p and back-contact k when the device is not operating so that should the motor e come to rest with contacts ! i and open the next operation of switch d will still energize winding r via this alternative circuit. A tell-tale lamp c of relatively low consumption is connected across switch d as shown and flashes in synchronism with the signalling lamps. If, however, one. of the signalling lamps fails, the reduced current in the electromagnet winding r is not sufficient to close the contacts n, m and the failure is thus indicated by steady illumination of lamp c.
