DERRICK FOR PUMPING OIL-WELLS.

Specification of Letters Patent.

Patented Aug. '7, 1906.

To all whom it may concern:

Be it known that we, GURnoN EUGENE KEELER and SILAs WILLsON GENsoN, citizens of the United States, residing at Haskins, in the county of Wood and State of Ohio, have invented certain new and useful Improvements in Combination- -Derricks for 1 Oil- Wells, of which the following is a specification. a

This invention has relation to a combination-derrick for oil-wells, Artesian wells, and other deep wells, and has for itsobject the provision of novel means for handling the sections of well-tubing while they are being inserted in or withdrawn from the well and while such sections are being coupled or uncou led.

T is invention has for its further object the provision of novel means for holding the pumping-jack in position while the pumping operation is being proceeded with.

Our invention consists in the novel construction, arrangement, and combination of parts hereinafter set forth.-

Referring to the accompanying drawings, illustratin our improvement, in the figures of which li re numerals designate corresponding parts, Figure 1 is a perspective view of a derrick and its appurtenant parts constructed according to our invention; and Fig. 2 is a fragmentary view, artly in section, and on an enlarged scale, of the lower portion of the derrick. v

The main body of the derrick is composed of two uprights, (designated, respectively, 1 and 2,) such uprights being of wood or of steel, as may be desired. The uprights 1 and 2 are so disposed as to form a frame which tapers outward sli htly from the top to the bottom thereof. T e uprights 1 and 2 have plates 12 12 bolted to their outer sides at their lower ends, these plates penetrating the earth and serving to maintain the lower end of the frame in fixed position. The frame is held rigid at its lower end by a cross-beam 13, which is secured in any suitable mannerto the uprights 1 2.

In placing the frame in position for operation it is inclined slightly to one side, so that the upper end will be inclined toward the oint where the well is to be driven, and the ame is sustained in the required position by guy ropes or cables 8 8, attached to the frame at 22 and which are provided with turnbuckles 9 9 and which are secured at their lower ends to anchors 10 10, located below the surface of the earth adjacent to the derrick. Stay-braces 11 are attached to the up rights 1 2 at a pro er distance from the bottom of such uprig t, and these stay-braces are secured to an anchor 14, located below the surface of the earth.

A sheave 15 is journaled between the upper ends of the uprights 1 2, and a cable 19 passes over this sheave and through two pulleyblocks 20 20, this cable 19 passing around a sheave located near the bottom of the frame and then extending rearwardly and carrying on its end a hook 24, by means of which it may be attached to a traction-cable in the usual manner.-

An arm 21, which is indented on its upper edge, projects horizontally from the upright 2 near the upper end thereof, the inner end of said arm extending through said upri ht 2 and being held in position by nuts, as s own in Fig. 1. A brace-rod extends fromthe outer end of the arm 21 to the upper end of the upright 1, and the upper pulley-block 20 is suspended from the arm 21 by means of a hook 27. The lower pulley-block 20 carries a hook 23, which hooks into an eye on the upper end of a pump-rod 7, which pump-rod is connected to the pump-jack 5 by means of a link 5, which is pivotally attached to the pump-rod 7 and ivotally attached to the pump-jack 5, as 0 early illustrated in Fig. 2. The 'pum -jack 5 is journaled in angle-plates 17 18, b0 ted, respectively, to the inner sides of the uprights 1 2 and the braces 11, and

said pump-jack is of substantially triangular form and has projecting upwardly from one corner a segment-piece the outer surface of which corresponds to an are described from the pivotal point of the jack. The lower corner of the jack carries triangularlates which are bolted together, so as to em race the side members of the jack and form a triangular frame, to which frame is pivotally attached a shackle-rod 25. V

A pump 6 is shown in Fig. 1 of the drawings, and in the condition of parts shown in thls fi .ure the apparatus is adapted for pumping, w ich is effected by imparting a reciprocating movement to the shackle-rod 25. This reci rocating movement is imparted to the shaclile-rod by a pitman, which is shown at the leftehand end of the shacklerod in Fig. 1 of the drawings, this p'itman receiving movement from the crank-shaft of an engine. (Not shown.) During the umping operation the cable 19 is allowed sufficient slack to permit of the rise and fall of the pump-rod 7 but if for any reason it is desired to draw the pump-rod out of the Well the pump-rod is uncoupled from the .pum jack 5, and by exerting traction on the cab e 19, which may be done by attaching the hook 24, carried by the cable 19, to a ro e which is Wound around a drum operated an engine or in any other suitable and "wellknown manner, the pum p-rod will bedrawn upwardly and out of the pump. The cable 19 -'and the pulleys 2O 20 are not only utilized for drawing the pum -rod out of "the pump, but, as will be readi y understood, may be utilized for raising, lowering, and otherwise handling the well-tubing and sustaining the sections of the same as they are being coupled and uncoupled when placing them in the well or takingout thesame.

We claim '1 The combination with an upright flame, a notched arm projecting horizontally from said frame near 1138 upper end, a hook engaging said notched arm, of a pulley-"block susended'from said hook, a second pulleyblock disposed below the first-named pulleyb'loc'k, a sheave located at the upper-end of the frame, a sheave located at the lower end of the frame and a cable passing over said sheaves and throughsaid pulley-blocks.

a second 2. "The combination with-a frame composed of uprights attached together at their u per and -lower ends, of an arm; rejecting om said frame near its upper end? a ulley-block carried by said arm and adjusta hle thereon,

u-lley-block disposed below the first-named ulley-block and a cable assing through sai pulley-blocks, of a pump aving a pump-rod connected to said second pulleyblock and means for vertically moving the pump-rod independently of the movement of said pulley-block, substantially as de: scribed. v

3. The com'bina'tion in a derrick for wells, of up'rights connected at their upper and lower ends, andeonstituting a frame, a horizontally-ex tending 'notched arm carried by said frame near its upper end, a hook carried by saidarm and adjustable thereon, a pulle-yblock carried by said hook, a second pulleyblock disposed below the fir t-named pulleyblock, a hook carried by said second pulleyblock, a pui'np 'rod engaged by said hook, sheaves-carried'by said framepa cable passing over said sheaves and through said pulleyblocks, pumping appara'tusconnected tosaid pump-rodand-means for o erating thepimipmg apparatus, substantia 1y as described.
