PUMP.

'Application led January 11, 1926. Serial No. 80,404.

My invention relates to pumps and in particular to a combined pump and sand dislodging device.

It is my objectto provide a pump which combines means for elevating sand and loose material and for loosening material at the same time.

It is a further object to provide a mechanism which can be easily renewed, which will not stick within the pump casing and which can be repaired or re-sharpened at will.

Referring to the drawings:

Figure 1 is a side elevation of the cornplete device;

Figure 2 is an enlarged section on the line 2 2 of Figure 1, showing the lower end of the device;

Figure 3 is a similar view showing the upper end of the device.

Figure 4 is a cross-sectional View taken ,on the line 4 -4 of Figure 2 and looking in the direction of the arrows.

Figure 5 is a cross-section taken on the line 5 5 of Figure 2 and looking in the direction of the'arrows. v

Referring to the drawings in detail, 1 is the pump casing, having a guide head 2, in which reciprocatcs the pump n piston or plunger 3 having an attaching eye 4 at the upper end. This plunger has, on either side thereof, guide ribs 5 which work within guide walls 6 in the head 2. This pump rod or piston 3 is provided with an internal passageway 7 sealed by a ball 8 at its upper end, which fits within a cup 9 beneath a re-A taining pin 10.

Within this aperture 7 rotates a worm carried on a shaft 11. This worm consists of a straight wire or shoulder along its upn per portion, marked 12, which becomes a spiral wire or worin 13 in the lower portion, being wound around the wire 11.k This spiral wire works within a slotted sleeve 14 which has an end 15 in which is a slot 16 to receive this spiral wire. The lower end of this sleeve 14 is provided with shoulders 17 engaging with corresponding shoulders 18 on a screw sleeve 19. y

This screw sleeve 19 carries outwardly eX- tending shoulders 20 at the lower end thereof, but is provided with an internal aperture 21 andan aperture 22 within the sleeve 14, so that the wormr wire may pass therethrough freely and extend downwardly into engagement with the cutting plate which is hereinafter described.

The plunger 3 has threaded on its lower end an outwardly extending shoulder 23 having a plurality of cutaway portions 24 on the periphery thereof.

Below this shoulder but above the shoulder of a ring 25 carried on the screw sleeve 2O is a loosely fitting reciprocating collar 26 spaced at 27 from the plunger having an enlarged space 28 at the top thereof to provide a thin, upper, outer wall 29. This loosely fitting collar acts as a piston within the cylinder casing, one for lifting the san-d and other materials which are stirred up or broken up by the rotating cutter.

This rotating cutter consists of a spiral head 30 having'cutter faces 31 carried on a cutter head 32 which is suspended by a sleeve 33 on theurod 11, which is rotated by the spiralwire 13. v

This rod is loosely guided by the guide plate 34 held within the cylinder.

The head 32 is guided by a similar transverse plate carried within` a cylinder, as at 35.

Side openings 36 are provided, through which access may be had to the detachable portion of the collar 26, which consists of the plate 29 forming the upper part of this piston. Tt is held in position by screws 37.

The material which is dug up and lifted may be ejected through the exit openings 36.

In practice, asythe plunger ascends and desc-ends with its piston, the cutter knives are rotated, cutting the material and also elevating it by reason of the screw. At the same time, the pump lifts this material and ejects it through the openings 36.

In case a well has enough fluid in it to cover the pump before it reaches the bottom of the well, the fluid will enter through the opening 36 and the openings in the spider 35, in which instance very little if any sand will enter the pump. But when the depth of fluid in the well is not sufficient to reach the opening 36 even when the ,pump lis resting on the bottom of the well the fluid rises in the pump to its outside level through the openings in the spider 35 and carries with it the sand which is being agitaed and lifted by the member 30 and then drawn into the cylinder by suction. l/Vhen the plunger is lowered should the cylinder be partly filled, the amount of sand slushing up in the opening 2.1 would be so small it would not intcrtere with .the operation ot the pump.

At the top ot the sleeve 'le is a bearing against which the sleeve rotates as it is forced to the bottom by the plunger. rvlhe opening 16 Where the shaft il passes through is the onlyY place tor the tluid to enter. in case the air pressure has not vlitt-'ed the ball 8 there would be a very small amount ot' sand `vhich could reach that part. rihe opening 9 is merely to let the .air out in case vthere is a surplus ot fluid in the hole. 'liis allows the .plunger to drop Jirecly. To operate `the punip when it is lowered to the bottom ol' the hole ant the cutter 3l is setting on the bottoni thereof, it Will be noted that 35 is open and 'the upward stroke of the plunger vvill start 3l rotating and the suceer lifting materialup from the cylinder ot the pump, ejecting `the tluiil out yot the opening 36 and .any sand which may have gotten .up through the opening '27 and lodged `on top of :the sucker valve. lt vdesired the plunger may be let dovvn as many times as `the opera tor sees fit. Ordinarily it Will load to .its full capacity the first time it is lifted, as the valve 32 vcloses when the sucker valve passes below the opening 36, thereby leaving a suply ot fluid `or material between vthe valve 32 and the opening lt the plunger .is let down a Vsecond time and the cylinder is halt full ot' sand it will only go down that tar. Any tendency for the sand to get on top or the sucker valve and cause the plunger to become stuck in the pump is prevented by -the cup valve with its thin edge.

When operating the pump in .a `caving tormation, the plunger may be lifted as many times as the operator sees lit to operate the .member 3l to crush such formation. The

rotating member 31 Will crush any :torinations of this sort which may be picked up through the openings in the spider .35.

It Will be understood that I desire to comprehend Within my invention such modifications as may be .necessary to adapt it to varying conditions and uses.
