Abstract

843,431. Valves. EVERED & CO. Ltd. May 8, 1957 [Feb. 9, 1956], No. 4022/56. Class 135. A thermostatic valve comprises a rotatable plug tap d<SP>2</SP> which is removable and connects with a spindle n setting the fulcrum v of a thermal lever r actuating a gas valve e, means e.g. spring p retaining the spindle in the casing a and stop means n2, o<SP>1</SP> limiting spindle rotation to less than 360 degrees when the plug is removed, the spindle and plug, and the plug and its control knob c being allowed to connect with one another only in one relative angular position. Rotation of niting pin f<SP>2</SP> engaging a slot d<SP>5</SP> in the stem of the rotary plug cock allows gas to pass the cock, and by means of the screwed stem n having a pin n<SP>1</SP> and slot d<SP>6</SP> connection with the cock, adjusts a nut q carrying the fulcrum of the lever whereby a thermal bellows s actuates the valve e to maintain a set oven temperature. The valve is initially calibrated by axially shifting a bearing o for the lower end of the stem n by a lateral screw t entering a cam slot o<SP>2</SP>. Accidental disturbance of the calibration during removal of the plug is thus prevented.
