Filed: 1965-05-11
Abstract: 1,102,778. Valves. RADIATION Ltd. 1 March, 1966 [11 May, 1965], No. 19780/65. Heading F2V. A main control valve for a gas oven, incorporates a pawl and detent mechanism for preventing the control valve being actuated to turn on the gas supply when the oven door is shut, but permitting the control valve to turn off the gas supply when the oven door is shut, also permits the control valve to be actuated to turn on the gas supply when the oven door is open. The pawl and detent mechanism has a detent 39 in the form of a bent-over tag, mounted to move rotationally with the actuating spindle 22 and control knob 21 of the control valve A<SP>1</SP>. The pivoted pawl 31 is connected to an intermediate portion 34 of a cranked lever 27 by means of a rod 35 which makes a loose sliding fit in respective holes in the intermediate portion 34 and the pawl 31. The rod is held in position by a collar 36 and a nut 37, and carries a compression spring 38 biasing the lever 27 and the pawl 31 apart. The lever 27 is pivoted on a limb 28 of a bracket 24 screwed to the body of the control valve and is actuated by the oven door C<SP>1</SP>. When the oven door C<SP>1</SP> is open, the lever 27 and pawl 31 assume the position shown in full line and when the door is shut assume the position shown in chain-dotted line. In order to turn the control valve on, the knob 21 is pushed in and then turned anti-clockwise. If the oven door C<SP>1</SP> is open, the tag 39 will clear the tip 40 of the pawl so that there is no obstruction of the movement of the knob 21 and spindle 22. However, if the door is shut the spring 38 is shortened due to a small pivoting movement occurring between the collar 36 and the corresponding surface of the lever 27, and between the nut 37 and the corresponding surface of the pawl 31 and the tag 39 is biased into a position where it abuts against the tip 40 and prevents the control valve being turned on. If the valve is already turned on when the door is shut, it can still be turned off as the tag 39 will abut against the lower surface of the tip 40 and raise the pawl 31 against the biasing of spring 38.
