ROD-SUPPORTER FOR OIL-WELLS.

SPECIFICATION forming part of Letters Patent No. 683,555, dated October 1, 1901.

Application filed January 28, 1899- Serial No- 703,'703. (No-model.)

T0 aZZ whom it may concern:

Be it known that I, WILLIAM E. DODGE, a citizen of the United States, residing at Roll, in the count-y of Blackford and State of Indiana, have invented a new and useful Rod- Supporter for Oil-Wells, of which the following is'a specification.

This invention relates generally to oil well apparatuses, and more particularly to an improved construction of rod-support or the means for connecting the polish-rod with the walking-beam.

The object of the invention is to provide a rod-support which can be quickly and easily adjusted as circumstances may require; and another object is to provide a support with a hinge connection whereby any shifting of the beam will not aifect the rod; and a still further object is to provide means whereby the rod or support can be revolved as needed without interfering with each other.

With these objects in View my invention consists, essentially, in the employment of a threaded red, the trunnion having a threaded hub through which said rod passes, and a yoke hinged to the bottom of the threaded rod and carrying a swivel-coupling intended to receive the upper end of the polish-rod.

The invention consists also in the employment of a supplemental top for the attachment of the elevating-ropes.

The invention consists also in certain details of construction and novelties of combination, all of which will be fully described hereinafter and specifically pointed out in the appended claim.

In the drawings forming part of this specification, Figure l is a front elevation, partly in section. Fig. 2 is a side elevation, and Fig. 3 is a detail sectional view, of the hinge-joint and swivel connection.

In carrying out my invention I employ a rod A-,which is threaded from end to end, as clearly shown, and at its upper end is slightly reduced and threaded, as shown at A, for the purpose of attaching a supplemental top B, said supplemental top having a square shank B and a cap E the purpose of this top being to serve as a convenient point for at taching the elevator-ropes whenever it is desired to draw the rods from the wells. The lower end of the rod is also reduced and a suitable wrench in either direction.

threaded, as shown at A for the purpose of connecting said rod with the upper member 0 of the hinge-coupling, the lower member D of said coupling being connected to the upper member by means of the hinge-pin E, both the upper and lower members of the coupling being forked or made in the form of a yoke, as clearly shown, the arms of the upper member being adapted to fit between the arms of the lower member, and the pin E is securely fastened in the lower member by means of a set-screw E, thereby preventing dislocation. The bolt F is swiveled in the lower coupling, the lower end of said bolt being enlarged and provided with a threaded socket F to receive the threaded end 01": the polish d G, and the bolt F'is also formed with a collar F which bears against the bottom of the lower coupling member, and thereby prevents any upward movement of the bolt, and the jam-nuts F upon the upper end of the swiveled bolt prevent any-downward movement, thereby securely connecting the swiveled bolt within the coupling. The trunnion H, which works upon the end of the walking-beam, is formed with a threaded hub H, through which the threaded rod A passes, and working upon the threaded rod, above the hub, is a locking jam-nut I, which is adapted to be turned down upon said hub after the rod has been adjusted, and thereby securely lock the trunnion and rod in their proper positions. The rod A is threaded and works through the threaded hub in the trunnion in order that the said rod may be adjusted up or down, as the requirements of the pump operations may require, and in order to effect such adjustment it is only necessary to loosen the locknut I and then turn the rod by means of The swivel connection with the polish-rod enables the threaded rod to be turned in either direction without aflfecting the polish-rod, and it will also be understood that the polish-rod can be turned whenever desired without interfering with the threaded rod. By means of the hinge-joint between the sections of the coupling a direct or vertical stroke of the polish-rod is insured, and in case the walking-beam or trunnion should be shifted so as to throw the threaded rod to one side or the other the direct stroke of the polish-rod will still be maintained, and no undue strain will be thrown upon said rod. i

It will thus be seen that I provide an exceedingly cheap and simple appliance for oilwells and by means of which numerous adjustments can be had Without taking the apparatus apart, and it will be noted also that by means of my apparatus considerable manual help can be dispensed with.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

A rod-support for oil-wells comprising in combination the threaded rod A slightly reduced at its upper end, the supplemental top attached to said end, said top having a square shank B and a cap 13 the hinged coupling comprising the upper member 0 and lower member D, said members being connected by means of a hinge-pin E, the bolt F swiveled WILLIAM E. DODGE.
