Abstract

321,085. Woosnam, A., (Automatic Sprinkler Co. of America). Dec. 3, 1928. Sprinklers, automatic.-A sprinkler apparatus of the kind in which a pump is employed for supplementing the water pressure in the system should it fall below a predetermined level, is provided with automatic means for testing the effciency of the pump-driving means at recurring intervals, in combination with means for indicating or recording when such automatic means have come into operation. As shown, the pump D is driven by an electric motor L. A pipe from the main riser E supplies a pressure responsive device or gauge G. If the pressure in pipe E falls below a predetermined level, a member in the gauge makes contact at H, closing the electric circuit of the motor and starting the pump. When the pressure is re-established, contact is made at H<1>, opening the circuit. A second gauge N similarly controls audible or visible signalling or recording devices I, I<1> which may be at a distant station when the pressure falls or is re-established. For testing the efficiency of the motor, pump, and control gauges, an outlet valve R from the pipe E is opened at recurring intervals, by means of a cam P<1> on a wheel P. The wheel is driven at a predetermined rate by a clockwork or other suitable device T. The indicating means I, I<1> give notice that the test has been made.
