Combined Pump and Motor.

Patent for a new and improved pump and motor. This design "is to produce a simple apparatus which may be connected with a main water or service pipe and which will operate by the fluctuation of pressure in said main or pipe so as to operate the pump. The device is especially advantageous in raising water from a well or cistern to a tank placed at a higher elevation, or it may be placed on a pump in place of an air-chamber and used as a feed-pump for a boiler or on a hydraulic ram as an auxiliary pump" (lines 9-18)
