UNITED STATES PATENT OFFICE.
JAMES W. OAHILL, OF MADISON, INDIANA, ASSIGNOR TO HIMSELF AND A. S. DAVISON, OF CINCINNATI, OHIO.
IMPROVEMENT IN PUMPS.
Specification forming part of Letters Patent No. 59,708, dated November 13, 1866.
To all whom it may concern:
Be its known that I, J AMES. W. GAHILL, of Madison, in the county of Jefferson and State of Indiana, have invented a new and Improved Force-Pump; and I do hereby declare the following to be a full, clear, and exact description of the same, sufficient to enableone skilled in the art to which the invention appertains to make use of it, reference beinghad to the accompanying drawing, which forms a part of this specification, and in which my invention is represented by a vertical central section.
The cylinder has inductiouopenings at its mid-length and valved eduction-openings at each end. It is traversed by two valved pistons attached to a single pump-rod, delivering the water alternately at their respective ends to a common discharge-pipe.
In the drawing, A is the cylinder, having induction-openingsB B and eduction-openin gs O D, guarded, respectively, by valves E F, which open outward. From the eductionopenings proceed pipes G H, which unite atI and constitute the dischargepipe.
Supported by the upright pipe H is the pivoted handle J, to whose upper end is attached the pump-rod K, on whose lower end are the piston-heads or plnngers LM. Each of these pistons havevalves Z Z and m lm,respectively, the upper valves opening upward and the valves of the lower piston opening` downward, as seen in the ligure.
rIhe operation is as follows: When the plungers are depressed the valves m m are closed, and the water below the piston M is pressed through the eduction-opening D into the pipeH toward the discharge-opening. The valve E during this time closes the opening O, and the water-above the piston M is passing through the valVe-openin gs in the piston L. Vhen the return motion is made by the raising of the pistons the valve E is raised, the water passing out at the eduction-opening C, and thevalves ZZ on the piston L are closed. The lower valve, F, is closed, and water enters the cylinder at the induction-openings B B, and passes through the valve-openin gs in the lower piston. A waste-water valve is arranged on the pipe H to empty the water above that level in the pipe.
Having described my invention, what I claim therein as new, and desire to secure by Letters Patent, ist The arrangement of the plungers L M on the sha-ft K, provided with valves, and operating as described in the cylinder A, which has its induction-openings at its mid-length and eduction-openin gs atits ends, as described and represented.
To the above specification of my improvement in force-pumps I have signed my hand this 25th day of August, 1866.
JAMES W. OAHILL.
