UNITED STATES PATENT OFFICE.
SAMUEL H. BAKEWELL, OF LANSING, IOWA.
PUMP.
SPECIFICATION forming part of Letters Patent No. 237,801, dated February 15, 1881.
' Application filed June 15,1880. (No model.)
To all whom it may concern:
Be it'known that I, SAMUEL H. BAKEWELL,.
reduce the comparative pressure of the water on the piston, and consequently the power required to work the pump and to throw water both as the piston ascends and descends, is the object of my improvements.
Figure 1 is a longitudinal vertical section of a pump involving my invention. Fig. 2 is a cross seetion on line 00 00. Fig. 3 is a face view of the valve.
Similar letters of reference indicate corresponding parts.
In theform of pump shown the piston B has a caliber the area of which in. cross-section is intended to be one-half that of the pumpcylinder Ali The piston has an operating-rod, a,a head, I), having perforations o to admit the water, a valve, d and a tube, 6, projecting upward to slide around a suspended tube, f, supported by flange g, clamped on a shoulder, h, on the pump-cylinder by screw-cap t. The flange has valves j for the egress of water that may get between the pump-cylinder and the suspended tube and piston. To the cap is screwed a pipe leading to an escape-spout. On the lower end. of the pump-cylinder is screwed a suction-pipe, D,-having a valve, 70. r The piston-tube is fitted nicely around the suspended tube and in the pump-cylinder.
The operation of the pump exhausts the air from the pump-cylinder below the piston, and in ordinary Wells, not over about thirty feet below the pump cylinder, the pressure of the atmosphere forces the water up into the vacnum as the piston risesk As the piston descends the water in the pump-cylinder below it all passes through the piston-valve into the piston-tube, the suspended tube, and the pumppipe. Thewateris forced upward in proportion to the relative capacity of the two tubes and the pump-cylinder below the piston at its highest point". Consequently the water is forced upward and out at the escape-spout at the downward plunge. as well as at the upward-lifting movement of the piston.
The parts 'can all be of metal, and no packing of soft material, as leather, be used.
The power required for the upward movement of the piston is diminished in proportion to the comparative size in internal crosssection of the pump-cylinder and the piston, within reasonable limits, in consequence of the effect on the power required in the downplunge of the piston.
The details of construction may be varied within the scope of my invention to adapt it to ordinary wells, driven wells, or otherwise, also to cisterns and wells of various depths.
Having thus described myinvention, I claim as new and desire to secure by Letters Patent- The combination of pump-cylinder A, having shoulder h, piston B, having rod a, head b, perforations o, valve 61, and tube 6, suspended tube f, having flange g and valves j, suction-pipe D, having valve 7t, and cap '5, sub stantially as described.
' SAMUEL HUNT BAKEWELL.
