IMPROVEMENT IN PUMPS AN-D FOUNTAINS.

Specification forming part of Letters Patent No. 127,651, dated June 4, 1872.

Specification describing a Combined Fountain and Pump, invented by JOSEPH J. SINK, of Philadelphia, Pennsylvania.

Combined Fountain and Pump.

In the accompanying` drawing, Figure l is a vertical section of my combined fountain and pump, and Fig. 2 an enlarged sectional view of the pump.

A represents a closed vessel of any suitable size and shape, and made air and water tight, and within this vessel, and projecting through one side of the same, is a pump, B, which communicates, through a pipe, D, with a basin, F,

secured to the top of the said vessel, a pipe, G,

of smaller diameter than the pipe D extending from a point near the bottom of the watervessel into the said pipe D, and upward through the latter to a point above the basin F, where it is furnished with a cock, a, and nozzle b. In an enlargement, d, of the pipe D, adjacent to the pump, there is a spring-valve, e, opening downward, and in the inner head of the pumpbarrel there is an opening closed by a springvalve, f, which opens outward. There is also a spring-valve, g, on the piston H, which closes the end of the hollowpiston-rod I, and the outer end of the latter is closed by a valve, h, pivoted to the operating disk or handle i ofthe pump in such a manner that it can be turned to one side in order to expose the hollow piston-rod. The water in the vessel A is forced upward through the pipe G by compressed air contained in the said vessel above the water, the height of the stream projected from the nozzle b depending upon the pressure, and also upon the extent to which the cock a is opened. The

water as it falls is caught in the basin F, from which it canbereturned to the vesselAthrough the pipe D and the pump, so that the same water can be used again and again, an essential feature when perfumed or colored waters are employed.

The pump is used both for supplying the vessel with waterand for keeping up the airpressure, and its operation is as follows: In order to fill the vessel to the required height water is, in the lirst instance, poured into the basin F,Which serves the purpose of a funnel, and the water is drawn from thisbasin through the pipe D into the pump-barrel, and forced from the latter into the vessel A. When the pump is thus used the valve h, at the outer end of the piston-rod, is closed so as to prevent any movement of the valve g,- hence the only effect produced by the reciprocation of the piston will be the opening of the valve e and the filling of the pump with water from the basin when the said piston is drawn outward, and when itis forced inward the valve e will be closed and the valve f opened, soas to permit the ejection of the water from the pump into the vessel A. If, after the emptying of the basin, the pump be still operated, air will be drawn downward through the pipe D Iinto the pump and forced from the latter into the vessel until the required pressure has been obtained. If desired, the. vessel A may be filled directly from any reservoir instead of from the basin through a pipe, X, (indicated by dotted lines in Fig. 1,) furnished with a valve openin g toward the pump. When the supply of water becomes partially exhausted from the vessel it can be returned to the same from the basin by a few strokes of the pump. If the air-pressure becomes considerably reduced when the basin is partially filled with water, the valve h, at the outer end of the hollow piston rod, is opened, which will permit air to pass through the said rod into the pump when the piston is drawn back, and to be forced from the pump into the vessel A when the said piston is pushed forward. The pump thus serves as a convenient means for filling the vessel with water and for keeping up the air-pressure, and also for returning to the said vessel the water received by the basin.

1t is not absolutely necessary that the pump should be contained within the water-vessel it may be arranged outside the same, providing the proper connections are made, by means of pipes, with the said vessel and basin. The basin and pipe D, leading from the same to the 2. The pump B, having; an inlet-valve, e, an` outlet-valve, f, and a hollow piston-rod, furnished, at its opposite ends, with valves, the whole bein g constructed and operated substantially as described.

In testimonyT whereof I have signed my name to this specification in the presence of two subscribing witnesses.
