Abstract
12,705. Woodward, A. M. June 13. Thermostats.-A compound strip A of metals of different expansibilities such as copper and steel, brazed or riveted together, is used for regulating the supply of gas to a vulcanizing-mould. One end B is securely fixed in the mass H of the mould and the other end bears against the spindle of a valve D in the gas-supply pipe. The strip A is heated by conduction from the end B, and the end C rises or falls with varying temperature allowing more or less gas to pass through the pipe E. Regulation for a given temperature is made by adjusting a set-screw pressing against the strip A near to the end B, or by raising or lowering the valve seat F.
