Filed: 1926-11-26
Abstract: 285,184. Marks, E. C. R., (Williams Oil- O-Matic Heating Corporation). Nov. 26, 1926. Electrically controlling fuel and air supplies.-A liquid fuel burner mechanism comprises an electric motor 2 operating a fan blower 1 and a fuel pump 5 for supplying air and fuel to a conduit 3 and burner nozzle 7 respectively, a thermal control device having a bulb 10 containing expansible Liquid arranged externally of the conduit and adjacent the burner nozzle, and a safety switch 31 which breaks the motor circuit when the flame is unintentionally extinguished but remains closed during the normal operation of the room thermostat of closing and breaking the motor circuit. The safety switch 31 consists of a mercury tube mounted in a frame 38 which is prevented when the burner is in normal operation from moving under the influence of a counterweight 39 to break the motor circuit by the engagement of a catch member 40 on the frame with a bimetallic strip 41 heated by an electric lamp 42. A circuit to the electric lamp 42 is completed when the burner is alight by the expansion of the liquid in the bulb 10 operating a bellows 8 to close a mercury tube switch 23. When the room temperature is such as to rock the mercury tube switch 43 of the thermostat to break the motor circuit at terminals 44 and so extinguish the burner, the mercury closes at another circuit to the lamp 42 at terminals 45 at the opposite end of the switch 43. On first closing the main switch S the switch 31 is held in the closed position by hand until the strip 41 engages the member 40. The bulb 10 is arranged in a housing 11 arranged above the nozzle 7 and is prevented from becoming excessively heated by allowing a portion of the air from the blower 1 to pass to the furnace through housing either by providing a separate air conduit or by providing openings 12 in the conduit 3. Alternatively the housing 11 may be open at both ends and a current of air is induced through it by the air current from the conduit 3 or the heat of the furnace.
