NITED STATES;
PATENT OFFICE.
JAMES E. HALLE'IT, OF GREENBUSH, NEW YORK, ASSIGNOR TO EDWARD H. JONES AND CHARLES W. NOYES, OF SAME PLACE.
IMPROVEMENT IN OSCILLATING PUMPS.
Specification forming part of Letters Patent No. 53,373, dated March 20, 1866.
To all 'zc/wm it may concern:
Be it known that I, JAMES E. HALLETT,
- ot' Greenbush. in the county of Rensselaer', in
the State of New York, have invented a new and useful Improvement in the Construction of Oscillating Force-Pumps; and I do hereby declare that the following is a full, clear, and exact description ot' the. construction and operation ofthe same, reference being had to the annexed drawings, making a partof this speciication, in which- Figure 1- represents a vertical central section of my invention, taken in the line xx, Fig. 2. Fig. 2 is a section of the same, taken in the lines a2 x2 of Fig. l. Fig. 3 is an isometrical View of the Heat or plunger B, exhibiting the grooves or gains which are designed to receive the leather or other suitable packing.
The object of this improvement is t0 dispense with one-halt' the number of valves necessarily used in a double-acting pump, by the employment of the oscillating iioat orplunger B, having holes a. a a a made diagonally through or radial to the center ot said floats B, and at right angles, or nearly so, to the axis of motion, and communicating with the lower right-hand and upper left-hand, or the lower left-hand and upper right-hand chambers. Said holes a a permit the water or other uid t0 pass freely through toward the vacuum or outlet valves b b.
It will also be observed, by the blue-arrow curves, that the liquid is forced through the holes a a, and then kept in check without valves being placed over them, this office being performed by the valves b b placed in the partition c. It will be seen, also, that the Water can pass freely through the mechanism of the pump.
The float or plunger B, used in connection with the cylinder A, partition c, and the ordinary slide-valve, would be readily converted into a steam-engine, this being the original design of the inventor.
A, Fig. l, represents the cylinder of the pump, made of a suitable proportion and truly bored out, and having heads d d bolted thereto, through the centers otl which pass the journals of the plunger B, and permitting the same to vibrate or oscillate therein. Partitions c c2 are inserted into the cylinder, as shown, and having valve-openings e e e e formed through them for the admission and discharge ofthe Water. These partitions are provided with leather or other suitable packing ff, which overlaps the metal edges and presses on the periphery of the shaft of the float B, in order to prevent the Water from escaping from chamber g to chamber h, or vice versa.
It will readily be observed that the opposite chambers, which communicate with ea h other by means ot' the holes a a a a, are filled and discharged simultaneously.
Having thus described the construction and operation of my invention, what I desire t0 secure by Letters Patent for thesaid assignees,
l. Providing holes or openings a a, arranged diagonally, or nearly so, with each other, and passing through the axis of oscillation of a plunger, B, as shown and described, the said holes communicating with vacuum or receiving chambers g h, for the purpose described.
2. In combination with the above, the cylinder A, partitions c c2, and valves b b', the whole operating in the manner and for the purpose substantially as set forth.
3. Fitting the packingff into grooves, and extending the same or permitting it to overlap the edges of the metal, when used in combination with the plunger B and partitions c c2, as described.
JAMES E. HALLETT.
Witnesses I. W. LA'rcHER, ALFRED HARLEY.
