Patented Oct. 13, 1936 UNITED STATES PATENT OFFICE COIVIBINATION OIL RIG AND PUMPING JACK 7 Claims.

This invention relates to a combination oil rig and pumping jack. The object of this invention is to provide an oil rig having a tower and walking beam thereon for the purpose of pumping oil from the ground. Another object is to provide a tower which may be used to lift pump rods and tubing from the well for various purposes and for cleaning the well, etc. A still further object is to provide a rig of the kind mentioned in which one side of the tower is left open so that lengths of tubing may be pulled from the well into the tower and then be removed through the open side of the tower to be piled on a rack preparatory for future use. A still further object is to provide an oil rig of the kind mentioned which is portable. A still further object is to provide an oil rig having adjustments whereby the rig may be properly positioned over the well so that there would be no side pull on the pump rods or tubing when they are being removed from or being replaced in the well, likewise there would be no side draft on the polish rod during the operation of pumping. These and other objects will be more fully explained as this description progresses.

Referring to the drawings in which the same characters of reference refer to the same part throughout the several figures. Fig. 1 is a side view of my oil rig and pumping jack. Fig. 2 is a view looking at the right hand side of Fig. 1. Fig. 3 is a plan view of Fig. 1. Fig. 4 is an end view of the walking beam and pivotal mounting therefor. Fig. 5 is a side View of a portion of Fig. 4, parts being broken away for convenience of illustration. Fig. 6 is a plan view of Fig. 5. Fig. 7 is a plan view of the upper side of the bearing block for the walking beam. Fig. 8 is a plan view of the bottom side of the bearing block for the walking beam. Fig. 9 is a side view of the rig showing it employed in handling the tubing of the well. Fig. 10 is a sectional view of the rig as seen from the line XX in Fig. 9. Fig. 11 is a side view of the construction at the upper end of the tower. Fig. 12 is an end view of Fig. 11. Fig. 13 is a plan view of Fig. 11. Fig. 14 is a side view of the bearings for the legs of the tower. Fig. 15 is a plan view of Fig. 14.

In the drawings is shown a tower having a face section as shown in Fig. 2 all the stationary elements which are welded together to make a rigid one piece element of that section of the tower. On either side of the section as shown in Fig. 2 is a structure as shown in Fig. 1, the parts thereof being bolted to'the legs 10 or Illa to form the tower.

Attention is called to the fact that the side of the tower opposite that shown in Fig. 2 is void of braces or truss rods and the like, leaving that side of the tower entirely open from top to bottom. At H is an element of the tower on which is rockably swung a cantilever element 12 to which is pivotally attached one end of the pitman l3, 5 the opposite end of which is rockably mounted on a bearing located on the cross member 15 of the tower. At 16 is a curve channel like element welded to the end of the walking beam, said element l6 being adapted to receive a cable I! 10 which is attached to the polish rod IS. The upper ends of said cable l8 being rigidly attached to the walking beam by any suitable method so that the polish rod will be lifted straight up and down during the reciprocal motions of the walk- 15 ing beam. At 19 is a cable attached to the lower end of the cantilever element l2, which leads to any suitable source of power whereby the cantilever element l2 may be rocked to the dotted position 12a whereupon the walking beam will be 9 rocked to the dotted position 14a thereby raising the polish rod l8 to pump oil from the well as will be understood.

At l 5 is shown a cross member of the tower on which is mountetd a plate 20 having legs 2| which are welded thereto, said legs 2| also being welded to the element 1 5 to make a rigid and permanent attachment of the plate 20, to the element l5. At 22 is a bearing block that is bolted to the plate 26, said bearing block 22 having a seat 23, therein, in which rests a shaft 24 to which is integrally attached a vertically extending shaft 25 on which is integrally mounted a bearing plate 26. At 21 is a block having a hole therein in which is positioned the pin 25, said block 21 resting on the plate 26 and being rigidly held in said position by nut 28 which is screwed on the upper end of shaft 25. The shaft 24 is held in the bearing 23 by bearing cap elements 29 which are bolted to the bearing plate 22 as shown in Figs. 4 and 5. At 14 and I4 are shown channel like elements positioned on either side of block 2'! and rigidly bolted thereto by the bolts 29 which pass through the channels 14' and I4" and the block 21 to form a rigid walking beam as shown at I4 in Figs. 1 and 3. At 30' is a series of holes in the channels l4 and 14'', said holes adapted to receive a pin on which is pivotally mounted the upper end of the pitman l3. It is obvious that the length of the pumping stroke may be varied depending 50 on which one of the holes 30 may be employed in connecting the pitman l 3 to the walking beam 14.

I will assume that the well is to be cleaned out and the tubing and the pump rods are to be removed therefrom. The method of removing the pump rods and tubing is the same in as much as Fig. 9 shows the rig in the process of handling the tubing. That process will now be explained.

The walking beam l4 must be moved so as to not interfere with the upper movements of the pumping rods or tubing. This is done by first disconnecting the pitman l3 from the walking beam l4 or the cantilever element l2 and then loosening the nut 28 whereupon the walking beam may be turned on the pin 28 to the position shown in the figures shown in 9 and I0. Now on the upper end of the tower is a pulley 30, having an axle 3|, which is carried in the said bearing block 32 being mounted on a plate 33 which rests on a pair of I beams 34 to which are welded the upper ends of the legs l0 and la of the rig. Between the legs I0 and Illa. is a cross element 35 which is welded to said elements I0 and Illa and to which is rigidly attached a hook element 36. One end of a cable 31 is attached to the hook element 36 and passes around a pulley-38 and over the pulley 30 and then downward through a pulley 39 which is attached to an eye 40 on the cantilever arm l2,,the cable 31, thence going horizontally to a power unit such as a Wench or the like on which the cable 31 is wound, thereby raising the tubing 40 out of the well. At 4| is a tubing board supported on the framework of the tower upon which a man may stand to guide the tubing as it is coupled or uncoupled from the joint below. After the upper joint of tubing has been uncoupled, the lower end may be swung outwardly through the open side of the tower as illustrated at 40' and piled on the pile of tubing 40 as illustrated in Fig. 9, likewise the tubing 40 may be picked up from the pile 40a and suspended over the tubing in the well to which it may be coupled and then lowered into the well preparatory for receiving the next length of tubing which will be handled in the same manner. Pump rods may also be handled in the same manner.

The tower is preferably supported on concrete bases 42 which extend into the ground and on top of which is a bearing plate 43 adapted to receive cross members 44.1: which are welded to the bottom end of the legs l0, IOa, lb, and I00. At 44 and 45 are cap elements bolted to the plate 43 and over the cross members 44.1; as means of rigidly holding the tower on the concrete base.

In erecting the tower it is important that the tower be so located that the curved element I6 is tangent with the center of the well, also the center of the well should be tangent with the left hand side of the pulley 30, therefore it may be necessary to shift the tower or the parts thereof in one direction or the other in order to accomplish this adjustment, therefore the elements 44 and 45 are provided with holes to receive bolts 46 and other holes 4'! are provided in the elements 44 and 45 to receive the bolts 46 so that the elements 44 and 45 may be shifted sideways thereby making it possible to shift the tower to make the desired adjustment. In addition to thisadjustment, further adjustments of the pulley 30 may be made as follows; The plate 33 is provided with holes 48 to receive bolts 49 which pass through the plate 33 into the I beam elements 34, and as shown in Fig. 13 the bolts 49 may be removed and the plate 33 shifted to the right or left to obtain the desired adjustment of the pulley 30 in a right or left hand position. On the shaft 3| of the pulley 30 is a series of collars 56 of varying thicknesses, therefore the collars may be removed from the shaft 3| and be replaced on the opposite side of the pulley and thereby shift the location of the pulley to make it line up with the center axis of the Well.

As previously described, the walking beam 14 is supported on a bearing block 42, the bottom side of the bearing block 22 is provided with a series of block holes 5| to receive the bolts 52 which pass through the plate 20 and into the bearing block 22, therefore the block 22 may be shifted on the plate 20 to make the desired adjustment on the walking beam.

Such modifications may be employed as lie within the scope of the appended claims without departing from the spirit and intention of the invention. Now having fully explained my invention, what I claim as new and desire to secure by Letters Patent is:
