SPECIFICATION forming part of Letters Patent No. 272,463, dated February 29, 1883.

Application led April 3, 1882.

To all whom it may concern: l

Beit known that I, HORACE W. NoItwooD, a citizen of the United States, anda resident of the city and county of Philadelphia, in the l same, andFig. l is a detail broken plan.

My invention has relation to elevators for raising water, sand, mud, grain, and othersimilar materials by means of the propelling force of ajet of steam, compressed air, or liquid un" zo der pressure; and it consists in the novel construction 'of the jet appliance or elevator, as

hereinafter specically described and claimed.

Referring to the accompanying drawings, I

will first describe the construction and operation of the jet appliance, in order that its application to a pipe for elevating and conveying purposes may be more readily understood.

Referring to Fig. 2 thereof, A represents a shell or body, of globular or other desired form,

3o provided with a discharge-opening, a, the interior of which is formed with a conical orftapered recess, a. Said shell has a chamber, B,

provided with radial lugs b b, upon which seats a pipe, G, the bore of which is of the same diameter'as that of the opening a. Said pipeis formed with a tapered end, c, which enters recess a', and is provided with an eccentric or crank, d, fitted in or resting between the edges or sides of a slot, c Said eccentric is secured 4o to a shaft, D, which has bearings in shell A,

as shown at d d2, and is providedwith an operating-handle, d3. By moving the latter the eccentric or crank d is oscillated,and its lower end working in slotc causes thetube C to reciprocate to move its end c to and from the walls of tapered recess a', to adjust the extent `of space between said parts to regulate the amount of steam, compressed air, or liquid under pressure designed to pass therethrough,

(No model.)

and thereby vary the dimensions or area of 5o f such jet formed thereby. f

E indicates an opening in the side of the shell A, communicating with chamber B, and is designed to receivea pipe leading from a y steam-boiler, air-compressor, or other source oi'jet-supply. Such construction aords a de;V

vice having a free and unobstructed opening -or bore from end to end, of the same diameter throughout, -a steam or 8vo.` chamber surrounding the walls of the central bore fora 6o part of its length. Said steam or other jetforming medium is admitted to said bore in the form of an annular jet, and the thickness or extent of the same may be Varied, as desired. `The radial lugs b b support the pipeG on all sides from end to end without materially diminishing the extent of the steam-chamber B, and prevent the pressure of such steam actingmupon the endo of pipe C to move the same laterally to cause au irregular opening 7o between said end c and tapered recess a'.

Such irregularity of said opening, if allowed to occur, would result inthe formation of an annular jet of greater power on one side than on the other, thereby reducing the effective working-power of said jet; but by employing the lugs b b the end c of pipe C is rigidly held in position to maintain its due relation with tapered recess a to form au annular jet-space between said parts, of equal area throughout. 8o

Such appliance is used for raising or conveying sand, mud, or other similar solid, fluid, or semi-tluid material by securing several or any number ot' them to a. pipe or conduit, F, as shown iu Fig. 1, wherein Gr represents the bed of a river designed. to be raised orexcavated. Said pipeFisformed in sections fffz, Sto., each such section being screwed toa nip ple, a2, flange-bolted to the ends of thejet appliances, as shown at a3. The end f3 of' pipe 9o F is ofsuch length that it will enter said riverbed, as shown atf, so that the pipe F will be. filled with Water to the line of the surface of the river, as indicated. The first jet appliance,

is located on said pipe a short distance above the surface of such water, as shown, and the remaining jet appliances maybe placed thereon at any desired distance apart, such distance depending upon the pressure designed to be carried in the steam-boiler or other source of jet-supply.

K represents a steam-pipe, connected by branches k k to thejet appliances, as shown, and is provided with a valve, Kl. Said pipe K may lead from a boiler upon a scow, L, as.

illustrated; or said boiler may be in any other suitable location. The sliding tube C in each jet appliance being duly adjusted to admit the required thickness or extent of annular jet through each appliance to pipe F, the valve K is opened, whereupon steam passes from pipe K into chamber B ot' each appliance, and thence through annular tapering` opening c2, to the interior of pipe F in the form of an annularjet, which travels near to or along the inner walls of pipe F, so that along the length of the latter at stated intervals a steam-jet is playing or entering therein, the result whereof is as follows: The jet A', or that one nearest the surface of the water, first creates or pro dnces a suction or vacuum in the space Friu pipe F, or in that part of said pipe included between the jet A and the top of the water in pipe F, which corresponds to the level or surface of the river. Said water in said pipe thereupon rises therein until iteuters the area orpath of annularjet in A', and is at once carried for ward with great velocity by said jet, until the force of the latter is about to expend itself; but before such result occurs said water has been carried to and projected into the area ot the next or second jet in appliance A2, and is pro pelled forward thereby, as described, and discharged from pipe F onto a chute, or otherwise, as desired. As soon as such water in pipe F rises therein and is conveyed therethrough the river-bottoni material G is forced into said pipe by the pressure of water above it, and rises therein until it meets the jets of steam, when it is propelled thereby through and outof said pipe, as above described. After being discharged therefrom the material may bc coilducted to an amalgamator i'or recovering any contained precious metal; or, it such riverbot tom material contain no ore, it may be deposited upon low lands or otherwise disposed of after passing out of pipe F.

In this manner my invention may be used for aiding in extracting ore from river-bottoms, dredging the same, raising water from wells or rivers, loadingand unloading grain, or forother similar purposes.

When it is used for loading and unloading grain, com pressed air is substituted for steam, and it becomes desirable to regulate the dis charge of the grain from the pipe F, so that said grain will not be propelled out thereot with suoli force as to comminute the same. Hence the sliding tube C in the jet appliance adjacent to the discharge-openiiig in said pipe F is adjusted to admit ajet of very small power into pipe F. .Consequently, when the grain reaches said jet, the latter propels the same forward or upward with force just suticient to cause the grain to pass out the discharge-opening in pipe F to fall to or be conveyed to a receiver without being broken into fragments.

It will be noticed that the material, after being drawn up in pipe F by suction induced by the first jet appliance, enters the area of said jet, or becomes confluent therewith, and is thereby forced, propelled, or carried forward or upward to next jet in pipe F, which in turn passes such material to the next jet above or beyond it, and so on throughout the entire length of the conveying tube or conduit, each successive jet giving afresh or new impulse to such material. Hence it may be conveyed to any desired distance or raised to any suitable height by merely increasing the number ofjet appliances and extending the length ofthe conveyer tube or conduit.

The end of pipe F always en ters the material to be raised or conveyed, so that it will rise to its level in said pipe, thereby diininishing'the extent of vacuum to be produced therein to canse such material to rise to the irst jet appliance. Such material being once set in motion to rise to said jet, said movement is maintained until all the material designed to be raised has passed into and been propelled through pipe F.

I have described steam and compressed air as the media for producing thejets; but l do notlimit myself thereto, as water or other liquid under pressure may be used, as well as any other suitable material.

What I claim as my invention is l. A water-elevator composed of a shell or casing having aligning induction and eduction openings ot' an equal bore throughout,a cham ber, B, provided with radial lugs b b, upon which rest the tube C, having tapered end c, entering a correspondingly-lorined recess in the induction-outlet, and a steam or side opening leading into said chamber, substantially as shown and described.

2. The combination, in a water-elevator, of the casing or shell A, having induction and eduction openings ot' equal bore throughout, tapered recess a', steam or side opening, E, chamber B, radial lugs b b, the pipe C, with tapered end c, and mechanism for adjusting or moving said pipe C, substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 15th day of February, A. D. 1882.
