438 THE HANDBOOK FOR PRACTICAL FARMERS 



in operating the ram, varies with the amount of fall and height to 

 which it is elevated. An increase in available fall or a decrease 

 in the height the ram has to elevate the water will cause a cor- 

 responding increase in the amount of water delivered by the ram. 

 Rams are used for a large variety of pumping duties, such as 

 supplying Avater for dwellings, hotels, factories, railway tanks, 

 stock watering troughs and so on. Water can be used directly 

 from the ram or from a storage tank which is kept filled by the 

 ram. The more common practice is to use the storage tank, as 

 in this way a large supply is always available. Water can then 

 be drawn from the tank as rapidly as desired for running water 



supply for bath room, 

 kitchen and closet in the 

 house, for watering the 

 stock at the barn or for 

 fire protection, irrigation, 

 etc. The ram operates 

 continuously, day and 

 night, consequently the 

 water used during times 

 w^hen there is a large de- 

 mand on the tank is re- 

 placed during periods 

 when the demand is low. 

 The advantages of the hydraulic ram are that its operation 

 involves no labor or expense, and, once started, it will continue 

 to 'pump day and night without attention, as long as the supply 

 of water is sufficient. 



Const ruction. — The miproved design of impetus valve used 

 on Gould's Rams gives exceptionally high efficiency and reliable 

 operation. The air chamber is large and all parts are strongly 

 built and carefully proi:iortioned. 



The sectional illustration shows the various working parts of 

 the ram, and gives a good idea of its strength and simplicity. 

 This sectional view illustrates the working parts of a ram, suit- 

 able for streams supplying eleven to twenty gallons per minute, 

 and for raising from fifty-five to one hundred gallons per hour 

 to elevations up to one hundred and twenty feet. By referring 

 to this view, it will be noted that the construction consists of 

 the air chamber; "A," the body; "B,'^ the shifting valve or air 

 inlet; "C," the check or inner valve; ''E,'' located between the 

 supply pipe and the air-chamber, and the impetus valve, ^'F," 

 located at the end of the supply pipe.
