Abstract
7696. Foster, R. F. April 15. Signals, foghorn, siren, reed, and whistle. - Relates to valve apparatus specially suitable for signalling devices of the kind described in Specification No. 7695, A.D. 1901. The supply of fluid under pressure for producing sound signals passing through a pipe is controlled by a lift valve a actuated by a piston c the motion of which is regulated by an oscillating valve e. A pipe M conveys motive fluid to a port 15 in the oscillating valve. The valve is divided by a partition N on opposite sides of which are inlet and outlet ports 13, 14 communicating with the piston chamber. The spindle 9 of the valve carries a weighted arm 20 working against a stop 21, and the valve is rocked from one position to another by a projection on a sliding rod S striking a pivoted arm 19, so that motive fluid is admitted to the piston chamber or exhausted therefrom. The valve may be placed vertically instead of horizontally.
