HYDRAULlC ELEVATOR.
SPECIFICATION forming part of Letters Patent No. 655,615, dated. August 7, 1906. Application filed January 26, 1899. $eria11To.703,428. on model.)
To all whom it may concern:
Be it known that I, GEORGE HENRY EVANS, a subject of the Queen of Great Britain, residing at Oroville, in the county of Butte and State of California, have invented certain new and useful Improvements in Hydraulic Elevators; and I do hereby declare that the following is a full, clear, and exact description thereof.
The present invention relates to certain new and useful improvements in that class of machinery known as hydraulic elevators for use in the elevation of water, dirt, gravel, or other suitable material; and it consists in the arrangement of parts and details of construction, as will be hereinafter fully set forth in the drawings and described and pointed out in the specification.
The object of the invention is to lighten the load of the material forced upward through the elevator-pipe in order that the efficiency of the propelling jet or column of water used to elevate the load may be considerably increased.
In order to comprehend the invention, refence must be had to the accompanying sheet of drawings, forming a part of this application, wherein- Figure 1 is a side view in elevation, the basechamber, elevator-pipe, and portion of the water-supply pipe being in section. Fig. 2 is a detail sectional View of the water-pipe nozzle removed from the base-chamber, showing the air-reservoir and air-inlet pipe; and Fig. 3 is a top plan view of the said waterpipe nozzle.
In the drawings the numeral 1 is used to designate the elevator-pipe, and 2 the hollow base-chamber or seat, between the base-chamber or seat and the elevator-pipe there being interposed the contracted throat 3. The chamber or seat 2 is provided with two or more suction-openings 4, with which communicate the suction-pipes 5. In the lower end or mouth portion of the base-chamber or seat is arranged the nozzle 6 of the ejector-pipe 7. These parts as to working and arrangement are the same as the corresponding parts fully set forth and described in reissued Letters Patent No. 11,582, granted to me by the United States Patent Office on the 5th day of January, 1897, and consequently the same need not be described in the present application. IVithin the base-chamber or seat is located, preferably below the line of the suction-openings, an annular casing 8, which in the present case is illustrated as forming a part of or being integral with the nozzle 6 of the water ejector pipe 7. This casing forms an air-chamber 9, surrounding the nozzle 6 and from which the air escapes through the outletopenings 10, formed through the top of the easing, into the body of the base-chamber or seat. Through the said base=chamber or seat, preferably at its rear, extends the air-supply pipe 11, which taps the air-chamber 9, Figs. 1 and 2. This pipe extends from the basechamber or seat to the surface.
During the operation of the elevator the water ejected into the base-chamber 01' seat, at about three hundred and eighty (380) feet per second, will cause a partial vacuum and draw air from the air chamber into the basechamber or seat, which will be carried upward through the elevator-pipe. The force of the impelling stream will keep the air compressed in the discharge or elevator pipe. will be secured a water-elevator and an air= lift pump without the expense of a com pressor. Inasmuch as the air will lighten the water, a much greater discharge will be obtained than is now secured without the assistance of the air.
It will be readily understood that the location of the air-chamber with the base or seat is immaterial, as it may, if so desired, be arranged above the levelof the suction-openings. Hence I do not wish to be understood as confining myself to arranging the air-chamber directly around the ejector-nozzle nor to this particular style of base-chamber or seat.
Having thus described my invention, what I claim as new, and desire to secure protection in by Letters Patent, is-
1. In a hydraulic elevator, the combination of a base-chamber or seat having a suctionopening, an elevator -pipe connecting with said chamber or seat, an ejector-pipe, a casing in said chamber provided with a part constituting a nozzle for said ejector-pipe which Thus nozzle extends to the top of the casing and having an annular air-chamber provided with one or more openings through the casing-top exterior to said nozzle and through which air enters said base-chamber or seat, and an airpipe connecting with said air-chamber, substantially as described.
2. In a hydraulic elevator, the combination of a base-chamber or seat having a suctionopening, an elevator-pipe connecting with said chamber or seat, an ejector-pipe, a casing secured in said chamber by means of a flange located between the ejector-pipe and said seat, said casing provided with a part constituting a nozzle for said ejector-pipe which nozzle extends to the top of the casing and having an annular air-chamber provided with one or more openings through the easing-top exterior to the nozzle and through which air enters said base-chamber or seat, and an air-pipe connecting with said air-chamber, substantially as described.
In testimony whereof I have afiixed my signature, in presence of two witnesses, this 27th day of December, 1898.
GEORGE HENRY EVANS.
