Description: |
| Abstract:
This invention relates to that class of lifting and force pumps denominated "double-acting," in which two or more sets of valves and valve-chambers are used in addition to the valves located in the piston or plunger, the object being to produce a steady and uniform flow of water, and to avoid the friction caused by the use of metal, rubber, or other solid packing of the piston, which so greatly increases the power required to work the pump, by substituting water therefor; and, further, to cheapen the construction by substituting, in all places where two or more parts are connected, for the flanged and bolted joints, by which the different parts are commonly secured to each other, screw-threaded joints, which make watertight and strong connections without the intervention of any packing whatever; and the invention consists in the construction, combination, and arrangement of the different parts.
Claim:
A pump-case composed of the lower section A, provided with the inlet-valve b, section B, having a valved diaphragm, B', forming a guide for the lower end of the plunger E, and forming a waterway around the same, the working-barrel C, and the air-chamber D, provided with the contracted neck f, forming a guide for the upper end of the plunger, all constructed, arranged, and attached together. |
