Title: Improvements in or relating to tap or switch operating means for heating apparatus
IPC: A47J27/62
Filed: 1935-11-05
Abstract: 465,470. Thermally-actuated valves. MACDONALD, G. M. Nov. 5, 1935, No. 30527. [Class 135] [Also in Groups XIII and XXXVII] A thermal device for actuating a gas tap 104 or an electric switch comprises a ball 107 which is normally wedged in an inverted frusto-conical tube 106 of a material with a higher coefficient of expansion than the ball. Steel and zinc are mentioned as suitable materials for the ball and tube respectively. The tube is carried by an arm 105 which is secured to the tap handle 104 and in the position shown, with the ball 107 wedged in the tube 106, the tap is maintained in the open position. On the application of heat to the tube 106, for example by steam from a kettle 101 when it commences to boil, the ball 107 is released and runs down the tube to the right-hand side, which overbalances and turns the tap to the closed position or to a nearly closed position determined by an adjustable stop 108 coming into contact with the stove top. The device is reset by inverting the tube to allow the ball to run back into the conical end 106 where it wedges itself. In another arrangement the tap is spring loaded to close but held open by a catch. The thermal tube housing the ball is fixed and on being heated drops the ball into a cup carried by the catch, which is released to allow the gas tap to close. As before a separate operation is required to reset the device by wedging the ball into the conical tube. In a further arrangement the wedging action is effected automatically on opening the gas tap, the conical tube being carried by a spindle which is rotated through a large angle by means of gearing from another spindle for opening the tap and tensioning a closing spring. This large angle of rotation of the conical tube both wedges the ball and sets the tube in an approximately vertical position with the ball at the top, the weight of the tube and ball holding a release catch for the gas tap. On the application of heat the ball is released and its weight is momentarily removed from the release catch which is lifted by a spring to allow the gas tap to close.
