To all whom it may concern:
Be it known that I, Gurnnnnr BURNETT, a subject of the Queen of Great Britain, residing at Hartlcpool, in the county of Durham, England, engineer, have invented certain new and useful Improvements in Apparatus for Raising ater and other Liquids, of which the following is a specification.
This invention refers to an application applied for by me on 24th of October, 1884., Serial No. 146,350, for improvements in apparatus for raising water and other liquids, and particularly relates to the construction and application of steam shifting valves,
whereby I admit steam instead of air for the purpose of destroying the vacuum in the body of the pump, the advantage of steam instead of air shifting valves obviously being that on the admission of steam from the main steamport there will be less condensation than if cold air had been admitted by an air-snifting valve. These stcamadmission and steamsnifting valves arc,as described in the specifi' cation of application for patent before mentioncd, fixed on the top of the apparatus or pump, an equilibrium-valve being employed for the steam-admission, and attached to the said valve is a piston, the top of which is open to the atmosphere. A spindle for the purpose of starting the valve is provided. In some cases I may employ a spring or weight to as sist the valves in closing promptly, all as described in the before-mentioned specification, and in the valve-spindle, or prolongation of the valve-spindle, there is placed a steamsnifting valve for the admission of a small quantity of steam from the main steam-inlet.
Figure 1 of the accompanying drawings shows such a steam admission and snifting valve. 71 is the equilibrium steamadmission valve for opening or closing the main steam port or inlet G. h is the piston. 11 is the weight for assisting in closing the valve promptly. at is a screw-cap preventing the piston becoming displaced. t is a ball-valve, arranged in the spindle of the steam-admission valve, and communicating with main stcam'port by an aperture through which a loosely-fitting spindle, 13, passes, to the end of which is secured a float, i. The spindle of this description of steam-snifting valve may be provided with a collar, 13*,- as shown, which, striking against the spindle of main steanr admission valve, will assist in forcing it from its scat.
Fig. 2 shows in part vertical longitudinal section this combined valve,rnarked withcorresponding letters to that described with reference to Fig. 1. In this case a flat plate or disk, t, is used instead of a float, which, on receiving a blow from the rising water, operates the valve t opening into the main steampassage.
Fig. 3 shows an arrangement similar to Fi 2, except that the piston h is shown provided with a valve-like end, h which, on the piston 71 and steanrvalve h opening and rising, rests in a suitably-formed seating, and thus, while at the same time acting as a stop for the pisston, prevents any leakage of the steam.
Fig. 4 shows an application of a diaphragm, q, to a similar description of these combined valves, the diaphragm taking the place of the piston.
The action of the apparatus-such as described in the before-mentioned specification, but fitted with this improved steain-snifting valve-would be as follows, referring to .Fig. 1: The body of the pump a and part of the rising main being supposed to be filled with fluid, the pump is started .by turning on steam, or it may be necessary in some cases to raise and lower the valves h by hand, after which itwill continue working automatically. The steam thus being admitted through the steam-supply G, it acts on the under sides of valves h and piston h, and keeps the steamsupply passage open, and the pressure of the steam acting at the same time on the surface of the water forces it through the deliver valve, the rising main, and the delivery-pipe.
The pressure of steam having fallen to or below the pressure of water in the rising main, sufficient water will be returned as a jet through an injection-pipe and hastens the formation of a vacuum. This vacuum causes theinflow of liquid through the suction-valves. The simultaneous closing of the steam-admission valves h and the rising liquid strikingthe float or disk t,will admit a small quantity of steam through the steam-shifting valve 1 and the vacuum being thus destroyed the main steam-valve will be opened, and this opening allows the steam again to act on the surface of the water, and the above-described round of operations will continue automatically.
5 I claim as my invention 1. The combination, in a steam vacuum pump, ofthe valves h, the steam-pipe G, vesselA, and connections, the float t, stem t, passing through the tubular stem of the lower 10 valve h, and the valve t at the upper end of the stem, substantially as set forth.
2. The combination, in a steam -vacuum pump, of the valves h, the steam-pipe G, vessel A, and connections, the float t, stem t passing through the tubular stem of the lower valve h, the valve t at the upper end of the stem,
and the piston h, upon the stem of the upper valve 72, substantially as set forth.
