JOHN R. WARE, OF OSAWATOMIE, KANSAS.

PUMPING-JACK.

To all whom it may concern:

Be it known that 1, JOHN R. WARE, a citizen of the United States, residing at Osawatomie, in the county of Miami and State of 1 ative position with relation to the well to be pumped.

A still further object is to produce a ump ng jack of simple, strong, durable, lig t and inexpens ve construction.

With these general objects in view and others as hereinafter ap ear, the invention consists in certain nove and peculiar features of construction and organization as hereinafter described and claimed; and in order that it may be fully understood reference is to be had to the accompanying drawings, in which Figure 1, is a perspective view of a pumpmg jack embodying my invention and arranged in operative relation to an oil well pump. Fig. 2, is a top plan view of a portion of the same. Fig. 3, 1s a view partly in side elevation and partly in central vertical section of the pumping jack as withdrawn from operative relation to the well. Fig. 4,. is a section taken on the line 1V-IV of Fig. 3.

r Fig. 5, is a section taken on the dotted line VV of Fig. 3. I Fig. 6, is a section taken on theline VI+VI of Fig. 3. Fig. 7, is a sectional perspective view of a modified construction.

Referring to the drawings in detail, 1 indicates a pair of substantially parallel bars provided with abutment blocks 2, formed with sockets or recesses 3 at their inner sides by preference. A truss frame comprises upwardly converging bars 4 and 5 formed by preference with flattened'ends or feet 6 to engage the sockets or recesses 3. Each bar 4 crosses a bar 5 and is connected thereto by a horizontal transverse bolt 7 retained in position by a nut 8 or its e uivalent.

9 indicates a spacing s eeve interposed between the upper ends of bars 4 and 5 and pivotally mounted on the bolt 7 and said sleeve is provided with an elliptical tubular stem 10,

to receive the correspondingly formed end 1 1 of a tubular brace 12, the op osite end of said brace being formed elliptica at 13 to engage the elliptical stem'14 of a T-coupling 15 through which extends a tube 16. At one end the tube 16 fits in a socket 17 of a casting 18 and said casting is rovided with a plate 19, provided with a p urality of notches or openings 20.

21 is a casting fitting againsttheopposite side of plate 19 from tube 16 and 23 bolts which extend through said casting and the desired notches or openings 20 of plate 19, nuts 22 retaining said bolts in position.

24 indicates a pair of bars secured together at their front ends as at 25, and coupled as shown or otherwise to acable or its equivalent 26 leading to any suitable ower for operating the pumping jack as hereinafter explained, the rear-ends of the bars 24 fitting against opposite endsof casting 21 and pivotally connected thereto by bolt 27, a nut 28 engaging the bolt retaining it in position.

The op osite end of tube 16 from casting 18 is of attened or elliptical form in cross section as at 29 and engages the correspondingly formed tubular stem or socket 30 of a curved arm or are 31 provided with a peripheral groove 32. A U-shaped bolt 33 extends through the arm or are 31 and has its ends connected to sleeve 9. preferably by extending through the lugs 34 thereof and engaging the ends of said bolt are nuts 35. A U-shaped bolt 36 engages a notch 37 in casting 18, and at its opposite end is also connected to the sleeve 9, preferably by extending through lugs 38 projecting from said sleeve, nuts 39 engaging the ends of said bolt. By screwing said nuts 35 and 39 tightly upon their respective bolts, the casting 18 and arm or are 31 are clamped rigidly on the opposite ends of tube 16, and 1n conjunction with the tube 12 connectlng tube 16 with sleeve 9 produce a rigid triangular pumping jack of skeleton and light construction in which there is no possibility of tube 12'having any rotary or swivel movement around its axis or any possibility of the arm or are having swive or turning movement on tube 16.

40 indicates ears projecting from opposite sides of arm or are 31 and secured to the same are eye-bolts 41 pivotally linked to endent eye-bolts 42 extending through a block 43, the latter being held on bolts 42 by retaining nuts 44. 45 indicates a cross bar connecting base bars 1 and adapted to bear against an oil well casing 46 at opposite sides of which base bars I extend, the ump head 47 of the well occupying a lane elow draft bars 24, 'which'are dispose at opposite sides of pump tube 48. V j

49 indicates the piston stem of the pump, the same being disposed vertically and engaged by groove 32 of the arm or arc 31.

aid stem also extends slidingly through block 43, and engaging the stem just above the block is a collar, consisting preferably of two similar members 50 clamped by bolts 51 upon saidvstem.

In practice, as the power pullsthe cable in the direction indicated by the arrow Fig. 1, the jack rotates in the direction of the curved arrow Fig. 1, with bolt 7 as its axis of movement and through the instrumentality of the bolt 43 lifts the collar rigidly secured to the piston stem and thereby effects the ejection of the oil from the pump, if the well is an oil well. As the pull on the cable is relaxed, the jack gravitates back to its original position as shown in Fig. 1,- and permits the piston stem to drop back to its original position,it being understood in this connection that should'said stem or pump rod stick and fail to drop, the return ofthe jack to its original position will not be interfered with because block 43-will slide downward on the stem or rod and the curved arm or are will swing downward inward of the collar, the parts bein so proportioned that said arm or are wi pass said collar without conflict.

If it be desired to vary the leverage of the jack, nuts 23 can be removed from bolts 22 and the latter withdrawn from openings or notches 20 to permit casing 21 to be a justed upward'or downward as may be desired on plate 19, bolts 22 being then slippled throu h adiflerent set of openings or note es and tile nuts 23 secured upon the bolts to clam the parts in their new relation.

en it is desired to dispose the device in inoperative position to give convenient access to the pum bolt 27 is removed to ermit bars 24 to e disconnected from the ack and laid aside, the collar of the piston stem or rod 49 is then removedand the rods 42 are detached from block 43 'to permit the jack to be swung to the osition shown in Fig. 3, in which osition it can be held by inserting a stick etween the rear sides of bars 4 and tube 12, as indicated at 52 (Fig. 3). The block 43 can then be removed from the pump rod if in the way and relaced uponrods 42 to avoid chance of eing nusplaced. The bars 5 are then moved from the position shown in Fig. 1', to the position shown in Fig. 3.

If desired the pump head may be utilized as a means of support for the forward bars ed with sockets move rearward, whereas in the construction shown in Fig. 1, its tendency is to move forward.

From the above description it will be apparent that I have produced a umping jack embodying the features of a vantage enumerated'as desirable in the statement of the object of the invention, and I wish it to be understood that I do not wish to be restricted to the exact details of construction shown and described as obvious modifications will occur to one skilled in the art.
