    • 8258. Davis, G. H. April 8. Liquid supply controlled by variations of gas pressure; liquid-supply valves actuated through diaphrams; drip-feed apparatus.-An acetylene generator in which closed water and generating chambers are employed, and in which the water is forced into the generating-chamber under a gas pressure derived from the gas generated, is provided with an automaticallycontrolled valve in the communication between the chambers, and an initial pressure is obtained in the generator by introducing a small charge of water through a hand-operated pump. In the construction shown, water is supplied from the closed chamber A through a pipe F in which is fitted a valve d controlled by a diaphragm D under gas pressure. A charge of water at starting is forced into the generating- chamber A by withdrawing the plunger C of a pump C, a free communication with the pipe F being provided through apertures c when the plunger is returned. The water is distributed through a perforated pipe G and a screwed cap G is provided to give access to the pipes for cleaning purposes. The generating-chamber is provided with a removable screwed cover P for introducing the carbide holder, and a safety-valve E is connected with the pipe F .
