AROHIBALD WATSON WHITE, OF SAN JOSE, CALIFORNIA.
PUMP.
SPEGIFICATION forming .part of Letters Patent No. 291,250, dated January 1, 1884. Application filed May 11, 1883. (No model.)
To all whom it may concern: 7
Be it known that I, AROHIBALD 'WNVHITE, of San J os, in the county of Santa Clara and State of California, have invented a new and useful Improvement in Pumps, of which the following is a clear, full, and exact description of the same, reference being had to the accompanying drawings,making apart of this specification, in which- Figure 1 shows an elevation of pumps. Fig. 2 shows the supply-cylinder with the valves enlarged. Fig. 3 is a vertical section of Fig. 2.
My invention relates to that class of doubleacting pumps in which the water which is at I rest, in the descending pump partially counterbalances the resistance encountered in raising the ascending pump and it consists in the combination of devices hereinafter explained and claimed.
To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out. 7
In the drawings, A A represent the supplycylinders; B B, the plunger-valves; O O, the column check-valves; D D, the hollow pistons, and E E the delivery-pipes The hollow piston D is provided with the packing d, to'render the joint between it and the delivery-pipe water-tight. The supp] y-cylinders are provided with the perforations a a, to permit the inward flow of water, and also to admit the escape of the water when the cylinder is raised for repairs; Within the hollow pistonDis secured the check-valve 0, provided with guide-rods c a, sliding vertically in the head-block F, as shown in Fig. 3. This allows the valve to readilyzrise from or rest upon its seat 0 as the hollow piston moves up or down in the Below the check-valve O,
and rigidly attached beneath the hollow pis' ton, is a short cylinder, F, provided with the frame G, which supports the seat 13 of the plunger-valve B. This valve is provided with guide-pins b b, which steady its movements Now, when the piston begins to ascend the plunger-valve B is instantly closed by the downward pressure of water. As the piston continues to ascend, the water confined above it in the supply-cylinder has to escape by forcing up the check-valve C and passing into the hollow piston and upward through the delivery-pipe E. The valve-seat B has proper packing to prevent the escape of the water downward as the piston moves upward.
'What I claim as new, and desire to secure by Letters Patent, is-
In a double-acting pump, the supply-cylinders A and hollow pistons D, in combination with the plunger-valves B, provided with the guide-pins b, and located within the frames G, and the check-valves 0, provided with the guide-pins c, and operating within the hollow pistons D, all constructed substantially as and for the purpose set forth.
