(o1. 1oz- 155) This invention relates to a pump. An object of the invention is to provide a pump of the reciprocating type shaped to be lowered into a well and having a novel means for operating the same whereby the liquid in the well may be lifted to the ground surface.

Another object of the invention is to provide a pump in combination with an eduction tube, and

lo having operative connections between the tube and the pump mechanism whereby the pump may be operated by the rotation of the eduction tube, thiiough which the liquid is delivered from the we l. 1r A further object of the invention is to provide 'J a pump embodying a plurality of cylinders having reciprocating plungers therein, in combination with an eduction tube which may be rotated by a suitable" appliance at the ground surface, said tubing having an oblique ilange thereon so dispbsed, that when the eduction tube is rotated, the

flange will gyrate, with operative connections betweenthe ange and plungers whereby the plungers will be reciprocated to alternately elevate the liquid from the reservoir beneath and deliver the 5 same into the eduction tube for delivery from the well.

The invention also embodies a suitable valve mounted in the eduction tube which communicates some of the cylinders with the liquid reservoir upon upstroke of the corresponding plungers,

and simultaneously communicates the other cylinders with the eduction tube above the valve upon down-stroke of the corresponding plungers.

With the above and other objects in View, the invention has particular relation to certain novel features of construction, operation, and arrangel 4 Figure 1 shows a vertical sectional view oi the pump.

Figure 2 showsa fragmentary side 'view of the eduction tube', showing thevalve therein.

Figure 3 shows a cross-sectional view taken on the line I-I o! Flgmel. y

Figure 4 shows a cross-sectional view taken on the line 4-4 of Figure l, and V Figure 5 shows a side elevationof the pump as located in the well.

In the drawings, the numeral I designates the pump casing, attached to the lower end of which there is the lower head 2, approximately planoconvex in form. On the upper end of the casing there is the upper end-plate 3 mounted on which there is the head l, said headplate and casing being secured together by suitable bolts, as 5.

The numeral 3 designates the eduction tube which leads to the ground surface, land whose lower end extends axially through the upper 5 head and through the plate 3 and is tted into a central bearing 'I in the lower head 2. A suitable stuiling box 8 is secured in the head I and closely surrounds the eduction tube,6.

Between the plate 3 and the upper head l, and 10 housed within the said head, there is an annular thrust plate 9 through which the eduction tube also extends, and which isixed to said tube. Between the thrust plate and the head 4 are the ball bearings III on one side, and between said thrust 15 plate and the endplate 3 are the ball bearings Il on the other side of the thrust plate. These bearings run in suitable race-ways in the thrust plate, and in the endplate 3, and head I, as well.

'The lower portion of the casing I is inwardly 20 i thickened to fit closely around the eduction tube, and this inwardly thickened portion has the 4cylinders I2 arranged approximately parallel with 'rotate in outwardly converging planes, and the rollers of each cross-head ride against the inside 35 plane faces o! the tracks I9, carried by the inside walls of the casing l.

Fixed on the eduction tubeand located within the pump casing there is an obliquely arranged ilange 20 havingthe upper and lower outwardly 40 tapering faces 2I, 22, against which the upper and lower

beveled rollers

23, 24, ride. Fastened to each arm I4, and on the inside thereof, there is a yoke 25, which supports the upper and

lower rollers

23 and 24, all to the end that as the eduction 45 tube4 6 is rotated, the gyrating movement of the ange 20 will be transmitted through the

rollers

23, 24, and the yokes 25 to the corresponding arms I4 and plungers I 3 attached thereto. The plungers I3 will consequently bebreciprocated in a con- 50 stant order of succession around the axis of rotation o! the eduction tube.

Ducts 26 lead from the lower end of each cylinder I2 and communicate with the interior of the eduction tube through the ports 2l, and with 56 the well beneath through the ports 21'. These portsare separated into intake and discharge ports by the partition 28 which is fixed in the rlower end of the eductiontube and spans the same, as shown in Figure 2. There is an intake pipe 29 connected to the lower head 2, and in alignment with the eduction tube, and this intake pipe may extend on down any selected distance into the well. Ii' desired, itniay have l0 a conventional drill attached to the lower end thereof which may rest on the bottom of the bore to anchor the pump casing against turning. Any other conventional means found practical may be employed to' -anchor the pump casing against turning relative to the outside well casing 30. The pipe 29 may be perforated, if desired, to provide suitable inlets for the inflow of l the liquid.

As the eduction tube 6 is rotated, the plungers i3 will be reciprocated. As the plungers l3, which are connected with the intake ports 21', are elevated, liquid will be drawn in through said cylinders through the inlet ports 21', and simultaneously the plungers on the other side of the valve 25 '28 will be forced downwardly, and the liquidtherein Will be forced through the corresponding discharge ports 21 into the eduction tube, and thence out of the well. During this rotation,A it Iwill be noted that the rollers mounted on each crosshead I5 will bear against the plane faces 'of the tracks i9 and will thus anchor the arms fil against distortion due to torsional thrust imparted to them, and will insure a true vertical movement to the plungers I3. These plungers will be operated in a iixed order of succession so that an approximately constant and uniform stream, or quantity of liquid, will be forced into the eduction tube so as to cause an approximately uniform flow of 40I pumped liquid from the well.

The drawings and description disclose what is now considered to be a preferred form of the invention by way of illustration only, while the broad principle of the invention will be defined by the appended claims. What I claim is: n

l. In an apparatus of the character described, a casing, a head attached to the lower end of the casing, a plurality of cylinders in the casing, a plunger slidably `mounted in each cylinder, an arm upstanding from each plunger, a rotatably mounted tube within and extending below the casing and terminating within the head, ports in the head forming passageways between the 65 cylinders and that portion of the tubing extending below the casing, an oblique ring mounted on the upper portion of the said tubing, a yoke on each arm, rollers on the yokes operatively connecting the yokes to said ring, tracks in the casing, anti-friction rollers mounted on the arms above the yokes and movable along the said tracks, each track being arranged to accommodate one roller of each of the yokes between which such track is located, a partition in the lower portion of the said tubing, said partition being effective to divide the tubing into discharge and intake passageways, said partition being formed to wipe the ports in the head as the tubing is rotated, and so positioned in the said tubing as to temporarily close the opposing port in the head, as the corresponding opposite plungers reach the top and bottom, respectively, of the stroke, and to direct the discharge from each cylinder above the partition as the corresponding plunger is moved toward the head, and direct the intake of each cylinder from below the said partition upon the stroke of each plunger from the head, the operative connections between the tube and plungers being effective to cause each plunger to complete a suction and discharge stroke upon each revolution of the tubing.

2. An apparatus of the character described comprising a casing, a head attached to and eX- tending beneath the casing, and havingV a longitudinal passageway concentric with the head, a plurality of cylinders in the casing, each having a duct leading out from the lower end thereof and in communication with the passageway through the said head, a plunger in each cylinder, an arm upstanding from each plunger, inwardly converging tracks in the casing, outwardly diverging rollers on the arms movable .along the tracks, each track being arranged to accommodate one roller of each of the arms between which such track is located, a tube extended into the casing, said tube and casing being relatively rotatable, means at the lower end of the tube arranged to control said ducts, said means consisting of a partition in the lower portion of the said tube, said partition being effective to divide the tubing into discharge and intake passageways, said partition being formed to wipe the ports in the head during such relative rotation, and to simultaneously communicate some of the cylinders with the passageway through the head, and other of the cylinders with the passageway through the tube in a predetermined order of g succession during such relative rotation, operative connections between the tube and plunger arms whereby the plungers will be reciprocated upon such relative rotation of the casing and tube.
