TUBE-WELL AND PUMPIING M'ECHANIS'M FOR THF SAME.

SPECIFICATION forming part of Letters Patent-No. 349,339, dated SeptembercZl, 1886. Application filed December 8, 1880.Y Serial No. 21,839. (No model.)

To all whom t vmay concern:

Be it known that I, MATTHEW Tr-roMAs CHAPMAN, residing atAurora, in the county of Kane and State of Illinois, and a citizen of the United States, have invented new and useful Improvements in Tube-W'ells and Pumpof which the following is avfull description, reference being had to the accompanying drawings, in whichc Figure l is an elevation, the main tube bel lng in section. Fig. 2 is a section at line x of Fig. 3.` Fig. 3 is a detail in elevation. Figs. 4 and 5 are vertical sections of the parts represented. Fig. 6 is an end view of the part shown. Fig. 7 is a section at line y of Fig. 5, looking upward. Fig. 8 isa detail.V

My invention consists in providing the lower end of the main tube with a steel reamer to enlarge the bore, such reamerhaving corrugated edges, which force the dirt into the hole, and being provided with an oblong hole large enough to permit a full-sized drillor boringauger to pass, but against the wall of which ment.

a shoulder upon the strainer-tube will catch when such tube is inserted; in providing the strainer tube or point with a tube iitted at its upper end to the inside of the strainer-tube,

,and tapering downward to leave a space for Water between it and the strainertube for the purpose of aiding in preventing the strainertube from becoming lled with sand and sedi- The invention embraces other features, which will be fully hereinafter described in detail, and specifically pointed out in the claims.

In the drawings, A represents the main tube inserted in a suitable hole bored or drilled to receive it. B is a steel reamer on the lower end ofsuch tube A, provided with corrugated edges a., so shaped that the dirt will be vcar- The hole Z) Y through this reamer is oblong.

C is a strainer tube or point, the lower end of which can pass through the hole bin B, but the upper end of this strainertube is of such size that it cannot pass through such hole I).

Inside of the strainer-tube is a tube, af', the upper end of which is connected with the inside of the strainer-tube at or near its top. This tube a is tapering downward, leaving a space for water between it and the strainer.

'the tube C, which packing can' be expanded by a screw or wedge, as usual so as to fill the space between the strainer-tube and the main tube, and prevent the passage of water up and around the outside of such strainer-tube.

D is a check-valve.

d is a flexible valve-seat for the ball e.

F is a packing around the valve-extension. Its lower edge rests on a ring, f, which ring, when the parts are together, rests on the top of the strainer-tube C, or on a loose piece inserted above the strainentube. The valve-extension g is provided with a shoulder, lz, at its lower end,which receives and holds the ring f when the check-valve D is lifted away from the tube C. The packing can be compressed by pressing down the valve D, so that this packing will lill the space between the base ofthe valve and the tubeA.

'L' indicates a projection on the interior of the valve-extensionr g. Owing to continued use the ball-valve is liable to wear away until it falls through its seat, and the object of the projection i is to stop the further descent of the valve. G is another check-valve located at any suitable distance above the valve D--say from one toten feet. It is provided with an-expansible packing, I, which can be expanded by forcing down the conical grooved, serrated, or notched base.

H isa tube secured to the lower end of the extension of this valve G, and extending down and engaging with a bail upon the top of the valve D. This tube I-I is about haltthe diameter of the tube A, and the space between it and the tube A, and between the packing I and the lower end of this tube H, forms a cha1nber M. The ball of this valve also has a ieXible valve-seat.

K is a plunger valve case or cage in which a ball-valve is held by the projections j. The valve-seat is screwed into this cage K, and its lower end is provided with a recess or slot to engage with a bail upon the top of the valve G, -but in actual use this extension will usually be soine distance above the valve G. v

L is a tube connected to the valve-cage K,

will not fill the strainer.

and extending upward any suitable distancesay ten feet, more or less. At the upper end of this tube there is a long thread having a screwcollar, b', thereon, with one or more flexible packing-rings, Z, as shown in Fig. 5. At the upper end of the tube L is a pipe-coupling, Q, to the upper end of which is screwed a delivery-pipe, R. The packing-rings Z fill the space between the tube L and the main tube A. This packing can be handled in the usual manner by engaging the lower end of the valvc extension la with the bail upon thc valve G, and screwing down the tube R, and compressing the packing between the coupling Q and collar b. The valve at K and the packing l, in fact, together form a section lifting and force valve, and the water is delivered through the tubes L and It, which together form a hollow piston.

The operation is as follows: The reamer B. is used to enlarge the hole for the tube A, and its form is such that the dirt will be readily carried over into the hole. lt is attached to the lower end of A, and the hole through it permits the point or strainer C to be dropped into place after the tubing is all in, but does not allow the upper enlarged part of such strainerto pass. "W here there is sand in the water, and the latter passes directly into the main tube from the point the sand is liable to settle inside of the strainer and gradually ill it, interfering with the flow of water. The tube forces the water which flows into the strainer to pass into the main tube A through the lower end of this tube, and the action is such that the sand will be carried up into the tube A, and "When the pump is in operation, water will be drawn into the tube A, and if the supply of water is not sufficient to till the vacuum produced by the upstroke of the piston some air will be drawn out of the chamber M, creating apartial vacuum therein. At the downstroke of the plunger the upper check-valve will be closed, and while the plunger is descending water will low through the lower valve into the chamber M, filling the partial vacu um therein. At the next upstroke of the plunger water will be first drawn from the well through the strainer, and if the supply is not sufficient from the well a portion of water in the air-chamber M will ilow into the bottom ofthe tube H, and the air in the chamber will expand, producing a partial vacuum, as before, and the operation will be repeated. rlhus I increase the capacity of the pump by drawing water from the chamber M, as well as from the well.

The water which has been drawn through the valve G into the space above is forced through the hollow piston-rod L R at its downward movement, being carried through the valve-casc K, which closes while thc upstroke is being made, and with such upstroke the water is lifted and flows out through a pipe that may be provided therefor. The pistonrod being smaller than the well-tube a movement of the piston-rod one foot in the tnbeA raises water several feet in the hollow pistonrod. The packing Z, when the piston moves upward, operates as a suction-valve and water is then drawn through the check-valves into the main tube A. Vhen the piston moves downward, this packing operates as a forcevalVe, forcing water into the piston-rod. This packing is so far above K that sand will not reach it.

Prior to my invention ithas been customary to use a packing with a Valve; but with the prior construction, in withdrawing the valve, the packing was liable to slip off, so that in use this packing did not prove a success, as on withdrawing the valve the packing would be left in the well, and when the valve was returned the packing would get beneath the inserted valve and prevent its proper action. It will be seen that with the construction herein shown and described the valve can be readily withdrawn without detaching the packing, and at the same time the packing can be expanded to any desired extent between the shoulder or ring and the end of the valve proper by means of the conical portions. The tapering or conical portion of the valve entering the packing as the valve is forced down produces an extension'of the packing, making a tight joint between the valve and the tubing. When it is required to remove the valve for any cause, it will be seen that the tapering or conical portion allows the packing to slip therefrom by the act of removing, the packing passing to the extension or contracted portion below the taper, which permits the packing to resume its normal condition of a IOO less diameter than the diameter of the valve,

so that the valve, with the packing, can be readily and easily withdrawn, andthe packing is held from slipping off the contracted portion by the ring or shoulder.

Vhat I claim as new, and desire to secure by Letters Patent, is as follows:

l. The valve D, having a serrated, conical, or tapering end for insertion in a flexible packing, and provided with an extension, y, having a laterally-proj ecting ring or shoulder, h, substantially as described.

2. The valve D, provided with a serrated, conical, or tapering end for insertion in a flexible packing, and with the extension g, having a laterally-projecting ring or shoulder, h, in combination with the flexible packing for expanding the packing by forcing it into the conical portion, and at the same time, in

case of the withdrawal of the valve, forcing the packing from the conical or tapering portion onto the extension in contact with the ring or shoulder, thereby allowing it to contract, substantially as described.

3. The valve-case K, with its balLvalvc, in combination with the main tube A, the tube L, of such smallerl diameter than tube A as to leave a space between the two tubes, and the packing Z, secured to tube L, to iill the space IIO between it and tube A and leave a space belit and tube A and leave a Space between the tween the packing and case K, substantially as packing and case K, and the tube R, connected 1o described. with tube 1L above the packing, substantially 4.
