Letters Patent No. 101,493, dated April 5, 12870.

DPROVEMENT IN WALKING-BEAM AND STICKER-ROD CONNECTIONS FOR DEEP WELLS.

The Schedule referred to in these Letters Patent and making part of the Same- To all whom it ma/y concern:

Be it known that I, MARcnLLUs A. MORSE, of the city of Titusville, in the county of Crawford and State of Pennsylvania, have invented a new and useful improved Connection of Sucker-rods and lValking-beam for Operating Deep Wells; and I do hereby declare the following to be a full, clear, and exl act description thereof, reference' being had to the accompanying drawing making a part of this speciaction, in which- Figure l is 4a front or end view of my improve ment;

Figure 2 is a side elevation thereof; v

Figure 3 is a sectional view of the connecting-v joint.;

Figure 4 is a perspective view of the gib or pressure-block; and

Figure 5 is a perspective view of the set-screw.

Like letters of reference indicate like parts in each.

My invention, while useful in operating deep wells generally, is of especial value in the pumping of oil-` wells, since, to secure the greatest possible yield of oil, it is necessary that the piston be carefully ad-d justed in the working-barrel, at the required depth in the well, with especial reference to the location of the 'sand or oil-producing rock.

The sucker-rods extend from the piston up to the mouth of the well, and by a rod, which is jointed -to a stirrup on the end of the walking-beam, are connected with the latter.

Such connection, hitherto in general use, provides no means by which the piston can be suiiiciently adjusted, so as to operate at a point higher or lower.

My invention relates to an improved joint for effecting such an adjustment; and.

The nature of it consists in combining a solid mortised head-piece, having cylindrical trunnions, with a concave-ended setscrew, for holding au adjustable connecting-rod, which passes through the mortise in the head-piece, at any desired point of adjustment.

Also, in combining a'gib or pressure-block with an adjustable connecting-rod, mortised head-piece, and set-screw.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and mode of operation.

The walking-beam A is slot-ted at its forward end, and on the upper face of each of the bifurcations A', a concave seat is made for the cylindrical trunnions a' of the head-pece a.

This latter is a solid block of metal, except that it has a mortise, c, extending through it, through which passes the connecting-rod b, the lower end vof which is to be. jointed to the sucker-rods.

Also, a tapped hole is made in one side of the head-piece a at, or nearly at, right angles to the di-y rection of the mortise c, in which a set-screw, d, operates, the parts being so arranged that the inner end of the set-screw d shall bear against the connecting-rod b, or against a'gib or pressure-block, e, inserted in the mortise c hetweenthe two.

This pressure-block may be of any desired length, its inner face plane or corrugated, as also the tace ot' the mortise c opposite thereto, if so desired, the' object being, by turning the screw d tightly up against the block e', to produce so Vfirm a bite on the rod b that it cannot slip, even under the immense load that has to be raised with each upward stroke of the walking-beam. v

The block e may, however, be dispensed with, and a suiiciently secure bite be obtained by making the inner` end of the screw d concave or cup-shaped, as as d.

Then, when it is screwed well up against the rod l, the edges of the concave end will take so secure a bite on the rod b that it'will be held at any desired point of adjustment.

The concave-ended set-screw may, however, if so desired, be advantageously used with the pressureblock e.-

With .the devices described, it is but a moments work to raise or lower. the rod bin the mortise c, nothing being nesessary thereto except to loosen and tighten the screw d, which can be done with a wrench.

For convenience in holding the block e in place while the adjustment of the rod bis being effected, its rear face may be notched or rabbeted, as shown.

As an improved mode of attaching the head-piece a to the walking-beam, I hinge to it a cap, f, also slotted at its forward end, and on the under side of each bifurcation f make a concave seat, g, so that when the cap is closed down, as in fig. 2, the trunnions a. will play therein, as well as in the seat g ou the walking-beam.

A bolt his fixed in the body ofthe beam, having a screw-thread on its upper end.

A hole is made in the cap, through which the holt h projects when the cap is down.

To hold the cap down, and so keep the head-'piece a, in place, I place a cross-bar, i, which is perforated at about its middle point, for the purpose, and turn down onto it a threaded nut, t", being careful, however, not to screw it down so tightly as to make the frictionon the trunnions a too great.

The devices described are then easily taken out for repairs, or for other-purposes, and as easily replaced, and while in place are securely held.

They are simple in construction, cheap, and durable.
