Abstract

1,254,751. Road traffic signals on vehicles; lamp failure alarms. STEWART-WARNER CORP. 2 Jan., 1969 [4 Jan., 1968; 16 Dec., 1968], No. 3.52/69. Headings G4N and G4Q. [Also in Division H1] An electromagnetic relay for vehicle flashing light control has an inertia weight 50 driven througha gear train 30, 40, 44, 46. The relay has a yoke 16 on which an armature 18 rocks on one limb of the yoke between stops formed by the ends of a slot in the other limb of the yoke. A contact 24 on the end of the limb 20 of the armature 18 is normally engaged by a contact 26 on the gear-wheel 30 which is biased clockwise by a spring 38. The coil 14 is in series with contacts 24, 26 and when it is energized the armature 18 is rocked against the bias of a spring 22 to drive the gear train through the engaged contacts 24, 26. When the armature reaches the end of its travel the gears and weight continue to move and the contacts 24, 26 open to de-energize the coil so that the armature resets to its normal position. Just after the contacts 24, 26 separate a cam member 36 on the shaft 32 of the gear 30 engages a spring blade 58 to open contacts 60, 62 in the circuit of indicator lamp RI or LI. When the inertia of the gears and weight is overcome by the stress of the spring 38 the gears are reversed and contact sets 60, 62 and 24, 26 are closed in sequence, the later set reclosing when the gear 30 moves the contact 26 to its extreme position beyond the point of separation. The coil 14 is thus re-energized and the operation is repeated to cause indicator lamp flashing. A two coil attracted armature relay 98 (Fig. 4) having an armature mounted contact 118 co-operating with a fixed contact 120 may be mounted on the same base as the flasher relay and be arranged to ensure that on lamp failure the coil 14 remains energized so that when the contacts 24, 26 reclose after the first operation there is no drive applied to the gears and weight and the contacts 60, 62 are not operated again to give reflashing action. The relay parts may be shaped to give a compact construction (Figs. 7 to 17, not shown) and the extra relay may have a single coil (Figs. 15 to 17) whilst the flasher relay has an additional coil which is energized on lamp failure to retain the armature. In order that a hazard switch may flash the remaining lamps in the event of lamp failure, relay 98 is provided with two windings 108, 110 in series.
