EJECTOR FOR RAISING LIQUIDS.

SPECIFICATION `forming part of Letters latent No. 265,246, dated October 3, 1882.

Application filed June 2l, 1382. (Model.)

To all whom it may concer/n:

Be it known that I, LEON A. CoNoRD, ot Elizabeth, in the county ot' Union and State ot' New Jersey, have invented certain Improvementsin Ejectors for taising Liquids, otl which the following is a specitication.

My invention provides a simple device to be immersed in a liquid to be lifted and connected with twopipes, one conveying steam to it under pressure, the other leading from it and conducting the liquid to the point to which it is desired to lift it.. rlhisdeviee operates on the injector principle, and in -this specification I will refer to it as an injector.7

In the accompanying drawings, Figure lis a vertical section of a well and part ot' a building, showing the applica-tion ot' my invention to lifting the water from the well to the upper door ot' the building. Fig. 2 is a side elevation of the preferred form of my injector. Fie'. 3 is a longitudinal section thereot cut along` the lines 3 3 in Figs. 2 and 5. Fig. 4 is alongitudinal section thcreot cut on the lines 4 4 in Figs. 3 and 5. Fig. 5 is a transverse section thereotl cut on the lines 5 5 in Figs. 2, 3, and 4. Fig. 6 is a longitudinal section of a moditication cut along the line 6 6 iu Fig. 7, and Fig. 7 is a transverse section of Fig (i cut on the line 7 7.

In Fig. l, A'is the building or other structure into which it is desired to force water through a pipe, a.

B is a steam-boiler of any good construction.

I) is a steam-pipe leading therefrom, and which should or may be Wrapped with a nonconducting covering Ato avoid condensation.

C is a well ot' water, and D is my improved injector, shown as covered by a wire cage or strainer, c. The steam-pipe b enters this iujector at the bottom thereof, and the water'- pipe a leaves it at the top. The injector D is made ot' an external shell or body portion, E, formed in two halves, and clamped together by bolts d d passing through tlanges or ears e e. rlhe shell E is Jformed with a bore or tubular channel passing longitudinally through it, and into this are set two tubular pieces, i and G.

F is a steam-nozzle common to injectors, which is tixed into the shell nearest the lower end ot' its bore, and Gr is the contracted throat,

also common to injectors, which is set into the bore above the steam-nozzle, but with the tip of the latter preferably entering its lower end, asshown. ThesetubularpiecesFandGshould be made of luydmctalfare exteriorly conformed to`tl bore of the shell, and are retained in place therein longitudinally by having concentric ribs ff formed on them and eutering corresponding grooves cast in the oppostte halves ot' the shell E. The bore in the shell is enlarged around the lower end ot' the throat-tubeG and upper end of the nozzle-tube F to form the usual suction-chamber, j, into which the water from the well ows through two tubular channels or apertures, g g, cast halt' in each halt` of the shell.v NVhen at rest the water will risc through the injector and till the pipe a to about the same level as in the well, it being thus always in the throat Gr and in readiness at starting to be immediately acted ou by the steam. l/Vhen the steam is turned on, hy opening a cock, il, in the pipe b it passes through the pipe I) and enters the nozzle F, where its stream is contracted and its velocity correspondingly increased, so that in entering the throat G it encounters the column ot' water and sets it in motion, whereupon a stream ot' water is drawn in through the passages gg, and is constantly added to the upwardly-moving column, which continually receives the upward pressure ot' the steam. By this means I have 'succeeded in lifting water, either hot or cold, to a height ot' over eighty feet, and with sutticient steam-pressure it may be lifted to almost any height. Otherliquids-as oils, sirnps, extracts, Stemay be lifted as readily, my invention being inapplicable only to those that suffer deterioration from contactv with steam or from having the water ot' condensation mingled with them, or which are too dense to he readily moved by a steam-current.

Instead ot' steam, compressed air may be used with good eii'ect, an air-compressor or tank ot' compressed air the boiler B.

My torm of injector D has the merit of being cheap and simple in its construction and entirely devoid ot valves, stop-cocks, vents, dips, and other accessories com monly used on injectors as heretofore made. lt is not liable to disarrangemeut or to become inoperative, ex-

being substituted for cept by the entrance of dirt, stones, &e., into it with the water, and this is readily prevented by inclosing it in the strainer c. The cheapness ot' construction ot my injector constitutes one of its chief merits, rendering it applica` ble in many circumstances where the expense ot' a steam-pump would preclude its use. Its com pactness, lightness, and durability also contribute largely to its utility, the former making it readily applicable to locomotives for fill ing their tanks from wells, ponds, rivers, and the like in case of emergency. For this purpose the injector will be fixed to the ends of two parallel pipes, flexible orjointed, so as to permit the injector to be lowered into the water. The only portions of the injector liable to wear are the tubular pieces F and G, and these can be readily renewed at any time by sepa rating the half-shells E E, pulling them out, and putting newones in their places. The sealn where the half-shells join may be packed in any suitable way to prevent undue leakage; but a slight leakage will do`no harm, as the injectorisimmersedin the liquid to be pumped.

Figs. 6 and 7 show a moditied construction ot' the injector. The channel or bore in the shell E extends from the top downward, curves to one side, and extends thence upward, as denoted bythe arrows. The tubular pieces F and G are inserted iu the upward or right-hand portion of this bore, as shown, the watenpipe a being screwed into it at a and the steampipe b being' screwed into the other portion at b. There are three water-inlet passages, g g, as shown in Fig. 7. This construction saves the necessity of fitting the steam-pipe b with a U-coupling, as in Fig.- 1.

I am aware that it is not new to raise water by means of an injector or ejector immersed in the water and employing a jet of steam, and I make no claim thereto.

I claim as my inventionl. The combination, toform an injector-pu mp, ot' a shell, E, formed of two halves divided longitudinally, having a channel in each, forniing a longitudinal bore when they are united, and having lateral openings into said bore, with a nozzle-tube, F, and throat-tube Cr, fitting said bore and fixed in place therein, substantially as set forth. 5o

2. The combination ot' shell E, made in two separable halves, divided longitudinally, with a longitudinal channel through each, formingr a bore or passage when they are united, with nozzle-tube F and throat-tube G, iitting said bore, and having each a rib or shoulder, f, entering corresponding grooves in said bore, a nd with inlet-apertures g g, substantially as set forth.

In witness whereof' I have hereunto signed my name in presence of two subscribing it` nesses.V
