Filed: 1971-12-03
Abstract: 1311399 Burner control CALORIC CORP 3 Dec 1971 [16 Dec 1970] 56290/71 Heading F4T An ignition system for a burner 22 comprises a thermostat switch 30 which operates an igniter 10 having spark electrodes 9, 11 and simultaneously therewith energizes, through contacts 73, 74 of a relay 14, a heater coil 44 of a safety switch 16, to close contacts 48, 50 thereof to thus energize the actuator 20 of a valve 18 supplying fuel to the burner, the establishment of a flame at the burner 22 being sensed by a thermocouple 12, the current from which actuates the relay 14 closing contacts 73, 76 thereof to provide a second circuit to the actuator 20 whilst breaking the first circuit through switch 16 thereto and cutting off the supply to the heating coil 44. The coil 44 acts on a bimetallic strip 46 and if a flame is not sensed by the thermocouple 12 continued flexing of the strip 46 opens contacts 54, 56 in the circuit to the actuator 20 thus causing the fuel supply to the burner 22 to be cut-off. The igniter 10 could alternatively be of the glow coil type and in a further embodiment the switch 16 is replaced by two relays performing the same function.
