IMPROVEMENT IN APPARATUS FOR RAISINGILUIDS.

-ebp TO ALI. WHOM IT MAY CONCERN:

Be it known that I, JAMES PARKER, of Camberwell, .county of Surrey, Kingdom of Great ritain and Ireland, have invented certain Apparatus fcnRaising 'and Forcing Fluids and I do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying sheet of drawings, forming a part of this specification. i

The said invention relates to the employment of combined steam and air for raising and forging water and other liquids, the steam and air being mixed by means of a peculiar arrangement of jets and nozzles, and introduced into a tank or-reservoir, when itis caused to exert its pressure directly u pon the liquid to be raised without the aid of a pump or piston.

Description of the Drawings.

Figure 1 is an elevation showing the arrangement of tanks employed in carrying out my invention.

Figure 2 is a plan partly in section of an arrangement of valves and pipes employed in connection with the said tanks.v

Figure 3 is a side view of the said valves and pipes, and the apparatus for combining or mixing the steam and nir.

Figure 4 is a'section in the line xx, fig. 3,' drawn to an enlarged scale. Like letters indicate the same'parts in each of the figures. A is the steam pipe communicating with the boiler, which may be of anyordinary construction. The said pipe is perforated with a row of small holes, a. A tube o r pipe, B, is arranged parallel with the tube A, and is l furnished with a series of nozzles, b, each of which is arranged exactly opposite one of the small holes ain the tube A. When steam is admitted from the boiler to the tube or pipe A, it .will issue in small jets from the holes -or perforations e, and-passing through the open space between the said holes and the nozzles b, will enter the lcup-shaped apertures b in the latter, and carry with it a certain quantity of air which is compressed and forced 'through the said nozzles into the receiving-tube B. I prefer to make the apertures a in the tube A about` onetwelfth of an inch in diameter. -Thc air becomes compressed by the steam-jet in passing through the nozzles b, owing to the 'expansion of the steamitherein, and to obtainthe proper quantity of air with the least possible friction, I prefer to construct cach of the said 4nozzles with a length equal to about twelve times its internal diameter. The steam and compressed air are injected into a tank or reservoir', C, containing the water or other duid to be raised or forced, and acts onvthe same directly, without the aid of a piston, and discharges it from the' tank through suitable outlet apertures. The said tank C isso arranged, in relation to the surrounding water or other liquid to be raised er forced, as to refill by gravitation through a flap, D, or other valves opening inwards, in connection with pipes communicating with the said water or other liquid. If the height to whichvthe liquid in-the tank is to be raised is not more than the height of a column of water which would balance the steam and air-pressure in the tank, it is simply necessary to connect a discharge pipe, E, to the bot-tom of the tank C, and

extend the same to the l required elevation. If the liquid is to be raised to a greater height, a second tank is placed at the discharge end of the lirst pipe, a steam and air pipe being connected with thissecond tank.- In the same manner a third tank, or as many as are required, may be placed above the last one until the required height is obtained; 'lhe steam and air may be caused to act upon the surface of the water in each tank by means of a tube or pipe, F, in connection with the slide-valve G employed in connection with the first tank, and in like manner, the exhaust may, while the same is refilling, escape from each tank through the exhaust pipe e vof the same slide-valvc G. Td produce a continu-ous flow of water, two sets of tanks are employed, one set being refilled while the other is discharging. I prefer, in working the water tanks, not to empty them completely at each discharge, but to leave a little water, which becomes warm, and thereby presents a warm surface to the steam and air, and consequently prevents some of the loss from condensation. A further saving is eected by having aoating non-conducting substance upon the water in' the tanks. I also prefer to have the top of the tanks kept from contact with the water or fluid to beraised.

What I claim, and desire to secure by Letters Patent, is The combination of the steam p ipe A, and its perforations, and the pipe B, and its nozzles Z7, with the tanks C, their valves D, or their equivalents, andpipe E, for the purpose specified.

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

JAMES PARKER.
