DOMESTIC MOTORS.

engines must be made by hand, but after a few turns of the fly-wheel 

 the motion acquired is maintained by the engine. 



The engine is supplied with either a deep well-pump, or one for 

 use when the water is not more than twenty or twenty-five feet be- 

 low it. The former is a simple contrivance, tubular in form, so that 

 it can readily be inserted in artesian wells. The pump for use with 

 water at less depths is of special construction, provided with rolling 

 valves. It is bolted to the cooling cylinder, and worked directly from 

 the compression piston or plunger. With one or the other of these 

 pumps the motors can be adapted to every variety of circumstance in 

 which water is to be drawn from one point and conveyed to another. 

 Houses in the country can have as complete a water-supply, and have 

 it in as convenient a shape, as those in the city, and at but little 



greater cost. 



One of the best of this class of motors made for power purposes 

 is the Sherrill-Roper engine, shown in section in Fig. 11. The mamier
