Title: Control for preventing flooding of pot-type burners
IPC: F23D5/16
Filed: 1952-12-16
Abstract: 715,306. Valves. JOHNSON, R. W. Dec. 16, 1952, No. 31909/52. Class 135. [Also in Group XI] A valve member 14 controlling the inlet to a chamber 18 and actuated by a float 16 to maintain a constant level for feeding a liquid fuel burner of the pot type through an adjustable outlet valve 24 is also controlled by a flexible diaphragm 80 associated with a temperature sensing bulb 72, whereby the valve may be actuated by the float while the burner is ignited but is held closed when the flame is extinguished to obviate flooding of the burner. When the burner is not ignited a spring (not shown) urges a lever 56 in a clockwise direction about a pivot situated between an abutment 84 and an abutment screw 54 so that the latter engages an arm 49 which presses the valve member on to its seat. An extension 70 of the lever 56 may be pressed manually to allow the valve to open after which the burner may be ignited. The consequent increase in temperature of the bulb 72 causes the diaphragm to engage the abutment 84 to hold the screw 54 clear of the lever 49. In the event of the float 16 failing to close the valve, fuel passing over a weir 36 into a chamber 34 causes a float 40 to release a spring- loaded lever 42 to close the valve. An arm 48 is provided for resetting the lever 42 or for releasing it manually when desired.
