Abstract
1,177,283. Road traffic signals on vehicles. LEHIGH VALLEY INDUSTRIES Inc. 16 March, 1967 [24 March, 1966], No. 12415/67. Heading G4Q. In a thermomotive flasher 13 for vehicle signal lamps of the type having a snap element 14 and a pull ribbon 16 and contacts 17, 18 for cyclically making and breaking a load supply circuit in response to heating or cooling of the pull ribbon, the load supply circuit X, 17-19 and L is connected in a manner such that a load current sufficient to light the signal lamps does not pass thorugh the vane and pull ribbon. As shown when the emergency warning switch HS or direction indicator switch TS is closed the current through a relay coil 22 closes contact 24 so that the ribbon 16 is heated. The ribbon 16 expands and allows a contact 17 fixed to the vane 14 to snap away from the fixed contact 18 so that the lamps go out. The heater is now disconnected and allows the ribbon 16 to cool and after a certain time the contacts 17 and 18 are again made and the above cycle is repeated to flash the lamps. The flasher unit has a flexible connection 19 between the moving contact 17 and a terminal L and a pilot light can be connected in the earth circuit. The contact arrangement provides a flash rate substantially not affected by the load. In a modified flasher (Figs. 2 and 3, not shown), having normally open contacts (31, 32) a flexible connection (34) shunts the vane when the contacts are closed and load current flows. In further flasher units (Figs. 4-6, not shown), the heater 23 is removed and switching is achieved by heating the ribbon due to current passing through the ribbon and vane. The flash rate may be determined by a certain fixed load (L1, Fig. 4, not shown), competed to supply the heating current for the ribbon and the contacts of the flasher are then arranged to be connected to the load circuit (L2) requiring a large load. Alternatively flexible resistance connections (45, 53 and 54) may be arranged so that a part of the load current passes through the vane and ribbon but the main current is passed by contacts and the flexible resistance (45, 54) shunting the flasher.
