Hydraulic Ram

—A device whereby the energy of a fall of water is made to force a portion of the water to a great height. The water working the ram is supplied through a sloping pipe, and escapes through an opening; when its velocity exceeds a certain rate, it closes this opening by means of a balanced valve, which is made as light as consistent with strength; the sudden stoppage creates intense pre ure in the ram and opens a delivery valve into an air ve el, and thence drives the water through the delivery pipe to its destination. As soon as equilibrium is restored, the delivery valve closes, the waste opens and the vycle recommences.
