Abstract

3941. Leopold, O. March 3, 1908, [Convention date]. Actuating valves and cocks.-In apparatus for lighting and extinguishing gas lamps by varying the pressure in the gas mains, the free end of a fixed gas-pipe 20 is covered or uncovered by mercury in a cup 19, which is raised or lowered when the gas-bell is raised by means of a cam-disk 14 acting through a finger 16 and a shaft 17 on a lever arm 18 carrying the cup 19 ; the finger 16, under the action of the weight of the mercury, also acts as a brake. The cam-disk is turned in one direction only by projections on a collar on the bell spindle 10 acting on pins on the cam-disk. When the pipe 20 is uncovered, two semicircular passages 28, connected through passages in the gas cock with the inlet 2 and the burner respectively, communicate with one another, and gas is supplied to the burner. The gas - bell 8 is weighted by shot or the like, and may be operated by hand by means of a spring-pressed plunger 23.
