Abstract
815,370. Valves. MAIN Ltd., R. & A. Oct. 19, 1956 [Oct. 19, 1955], No. 29897/55. Class 135. An interlocking device between the adjusting means of a thermostatically controlled valve for a gas burner and a gas cock controlling the supply of gas to that valve for preventing the gas cock from being turned on or off unless the thermostat has been set to a maximum gas supply position, comprises, Fig. 2, a plug valve 14, with a T-shaped passageway which controls the gas flow from a supply port 18 to a branch 12, leading to a pilot jet, and a port 17 leading to a gas cock 22, which controls the gas supply to a relay valve 46 which is actuated by a thermostatically controlled valve 24, and mounted on the control spindles of the valves 14, 22 and the thermostat are knobs with integral discs 32, 33, 34 respectively, having arcuate cut-away portions as shown in Fig. 3, in which the pilot valve and the gas cock are in the off position and the thermostat in the open position. The main gas cock with disc 33 can only be turned when the pilot valve with disc 32 is turned on so that the recess 37 is opposite the recess 36, also, the thermostat can only be adjusted when the gas cock 22 has been turned on so that the recess 35 is opposite the recess 38. Similarly, the gas cock can only be closed when the thermostat is in the maximum supply position and the pilot valve 14 can only be closed when the gas cock is turned off. In a modification, the outlet from the gas cock is controlled directly by the thermostatically controlled valve.
