To all whom t may concern;

Be it known that I, WILLIAM MUIR, a citizen of the United States, residing at Michigan llnli, county of Placer, State of California, have invented an Improvement in "Ejectors for Miningl Purposes and Dredging; and I hereby declare the following to be a f ull,-clear, and exact description of the same.

My inventiorr relatesl to a device which is especially adapted to raise water orsand,mud, and gravel from mines` or depressed locations and for dredging bay and river bottoms, dac., and eject it at a considerable distance above the point from which it israised into lighters or otherwise.v

lt consists in certain details of construction, which will be more fully explained by reference tothe accompanying drawingsfin Figure 1 is a sectional elevation of the apparatus as designed for raising water alone. Fig. 2 is an elevation of .my apparatus, showing the movable suction-pipe' and` jointfor dredging purposes.

A is "a pipe ,through which water is brought` to the apparatus ,under a considerable pressure or head.

B is a converging chamber to which the pipe A is bolted and into Vwhich the wate therefrom is delivered.'

C is a cylindrical pipe having a diameter approximately equal tothe diameter of the smaller end of the chamber B, which delivers vinto the pipe C. llhis pipe C is movable in the cylindrical extension of' the chamber B, within which it ts, and a tight joint is made byineans of a gland D and suitable packing, forming what is known as/a stnlfi11g-box.

Eis a suction-chamber situated in line with the pipe C and having a screw-threaded opening into which the correspondingly screwthreaded end of the pipe. C is litted toltu'rn,

, with suitable collars to form ajoint and prevent leakage.

The-central port-ion of thc pipe C has an exterior polygonal flange C, by which the pipe C may-be turned, so that by reason of its screw-threaded end it can be advanced into the chamber E or retracted therefrom, the

through this is delivered into a cylindrical .central portion F2, of a diameter corresponding with that of the in ner end of the cone F. From the opposite -end of F2 the passage is again enlarged in the form of a conical diverging chamber F3, and through this end the Water is discharged into the chamber E from the nozzle F2.

The end of the chamber E which is in line with and opposite to the sleeve'F has a screw` threaded opening made in it, and within this opening is fitted a screwthreaded sleeve G, the central portion of which has a cylindrical passage, as shown, of larger diameter than that of the nozzle FZ. The end which is presented within the chamber E is made diverging or funnel-shaped, as shown at G', and the opposite end is again made diverging, as

shown at G2, and discharges into the delivery-pipe H, which is bolted to the side of the chamber E and is axially in line with the sleeves G F, pipe C, and inlet.

To the'lower part of the chamber E is connected the suction-pipe I, whichleads downward to the point from which water is to be raised. The' inner end of the pipe I opens directly into the chamber E and is provided With a valve 'J which opens inwardlyinto the chamber E and closes to prevent the return y of water Vthrough the pipe I.

In the operation of the device water being "admitted under a high pressure through the pipeA is delivered through the funnel-shaped passage B into the cylindrical pipe C, thence into the doub-le-fnnnel-shaped,sleeve F, and "being discharged from 'the nozzle thereof across the space between F3 and it forms a vacuum, which acts to draw the water up .through the pipe I and valve J and cause it to mingle with that which isbeing discharged from F to G, the whole being carried by the momentum of the body of water into the pipe H and raised to a height which -de'pends on the pressure of the supply-column.

An im portant featureof this invention is'the C and the` screw-threaded sleeves F and ipe I By this means the section G is first set at the proper point within the chamber E. The section F is screwed into the l)ipe C, and the latter is then adjusted by turninggit so'that l-by reason of the screw-threaded end which fits into the chamber Eit mav be advanced toward or retracted from, the sleeve G until the space between is such as to produce they highest eiciency and best result. As this may vary with the head or pressure of water or the height to which the wateristo be drawn or raised, it will-be manifest that' this con-` struction enables me to adjust the apparatus at all times so as to produce the highest elliciency.

The body of water delivered through the L part F? ofthe vsleeve Fis discharged as from a noz'ale with great velocity and axially into the sleeve G, and the funnel shape of the ends. F3 and G', respectively, of these sleeves acts to materially assist in the suction-and the eommingling ofthewater which is drawn into chamber E with that which is being forced through the chamber, so as to carry the whole body onward and upward anddeliver'it.

Either 6r both of the Vsleeves or. nozzles F and -G may be independently adjusted or removed by removing the cap of the suctionchamber without disturbing any other part.

In Fig. 2 I have shown" the chamber E as -closed at the bottom and having an opening l at the side into which'the slu'ice K is adapted to discharge sand or gravel in such quantities-- as the velocity andamou-nt of Awater will carry, and it is taken up and immediately propelled I through the discharge-passageand delivered with the water. A

As shown in Fig, the sluice K may be removed and a suction-pipe connected with v the passage leading tothe pointufrom which the water or material is 'to be drawn. This `pipe is constructed with la swivel or ball joint `I', so that itmay beturned about the joint. v .f-he material'is drawn' in by suction; It the ioint'of supply is gradually lowered, the joint 1n the pipe allows th`e end of the pipe to be depressed correspondingly, and if the supplypoint is lowered beyond .the length of the .pipe another section may be inserted, the

swivel-joint'adjusting it to the surface from suction-chamber.

should beat leastl equal to the diameter of the suction or delivery pipe and the flare of -the discharge pipe should be greatly increased, as shown by the dotted lines in Fig. 2. Having thus described my invention, vwhat I claim asew,.and desire to secure by Letters Patent, is-f 1. Asupply-pipe, a receiving-chamber with which it is connected, a suction-chamber separated from and in line therewith, a cylindrial sleeve having screw-threads fitting a -corresponding screw-threaded opening in the suction-chamber at one end, and a smooth cylindrical portion slidable through a stuifing-boxinto the receiving-chamber, ra means for rotating the sleeve so as to advance or retract it with relation to the suction-chamber,

a sleeve adjustable in the discharge end of the cylinder having a central cylindrical pas-v sage and conical ends, and a corresponding sleeveitting the opposite side of the suctionchamber axially in line with the first-named sleeve and with Vthe discharge-pipe, and a suction-pipe connecting with the -suctionchamber. Y

.2. A supply-pipe and contractedk receivinghead, a cylindrical pipe fitting and slidablo in said head, and a st-ulling-box to -make a.
