IMPROVEMENT IN STEAM-PUMPS.
To all whom it may concern:
Be it known that I, WILLIAM ARTHUR, of Newport, in the county of Campbell and State of Kentucky, have invented a certain Improvement in Steam-Jet Pumps, of which the following is a specification:
My invention relates to that class of pumps in which the steam is applied directly to the water in form of a continuous jet. My invention consists in providing a number of steam nozzles standing side by side, and with a separate water-tube to each, the tubes discharging into a common pipe or reservior. The object is to largely increase the capacity of the pump, which cannot be profitably done where a single steam-nozzle is used, as the steam does not operate to advantage in currents of large size.
The Figures 1, 2, and 3 show in section various arrangements for the application of my principle, all being substantially similar.
A is the steam-pump, ending in Fig. 1 in a head, B, from which extend a number of nozzles, C; the nozzles may be two or more in number, `according to the size of the pump. The nozzles are in line wit-h a number of tubes,
D, leading into the lwater pipe or chamber E. vF is the suction or water-supply pipe, extending from the supply water to the chamber G. In Fig. 2 the steam-nozzles (l and tubes D are Vshown vertical; the former may be more or less immersed in the water. The steam-pipe A discharges into an annular chamber, B,
from whence extend a number of curved nozzles, C, whose vertical ends are in line with the flare-mouthed tubes D. In Fig. 3 the steam-pipe A branches at a into two or more nozzles, G, which are associated with iiaremouthed tubes similar to those shown in the other figures. In Fig. 3 the water-pipes F are branched from two or more sides of the chamber G, their notched ends being immersed in the supply-water.
My improvement is especially applicable to pumps of large capacity, and I was led to the conception of the same from demonstrating by experiment that a steam-nozzle of large size does not operate in this manner with as good effect as one of smaller dimensions-that is,
ofcourse, taking account ofthe amount ofsteam expended and of water raised. v
l have illustrated my invention by three figures, which show various mechanical arrangements, but which all involve the same principle of action.
Any number of nozzles may be used, according to the capacity of the pump, and the form is immaterial. The nozzle C may enter theV
