Definitions
- connection between the line of sucker-rods connecting the piston (which is at the bottom of the well) and the working-beam consists of the connecting-rod attached to the working-beam, answering to an ordinary piston-rod, being smooth and polished, and working through a stuffing-box at the top of the well-tubing.
- To this rod are connected the sections of the sucker-rod, extending to the piston in the working-barrel at the bottom of the tubing. Adjustment vertically by raising or lowering the sucker-rod and piston to place the latterin its proper position for working effectively in the barrel is required. It is necessary to the operation of the pump that the piston shall be inserted in the working-barrel and the valves adjusted to their proper relative positions.
- Figure 1 is a side elevation of my improved head or clamp, the'end portion of the working-beam, and a part of the connecting-rod.
- Fig. 2 is a perspective view of the clamp and portion of the rod removed;
- Fig. 3 a perspective view of the end of the working-beam, and
- Fig. 4 of the plank or bearer E used therewith.
- A indicates the head or clamp; B, the connecting-rod connecting the sucker-rod with the working-beam, and O the working-beam itself.
- the head consists of two essential elements: first, the clamping part, by which it is connected with the rod so as to be capable of adjustment; second, the journal portion, by means of which a bearing is obtained in a suitable seat on the beam, and by which the proper position of the rod is maintained during the oscillations of the beam.
- the first of these consists preferably of two opposite metallic faces, a b, their proximate surfaces having hollow segments corresponding in some degree to the outside of the rod which they hold, said segmental cavities bearing such relation of size, curvature, or inclination to the rod as to admit of tightening the segmental portions upon the latter by compression.
- Such compression may be readily obtained by screwbolts 0 c, passing through the parts, or by other means of effecting a firm hold upon the sides of the rod by compression of the inclosing portions, the means being unimportant so long as sufficient force is employed to make it effectual; but it is essential that there should be left a space, d, between the clamping-surfaces, so that indefinite pressure may be applied.
- ⁇ Vhen bolts are employed, one or more may be used on each side of the rod; but it is necessary to loosen that upon one side only to enable the rod to be moved, the jaws then open ing as if hinged on the other bolt or bolts.
- this clamp Connected with this clamp, or with one of the parts thereof, is an axis consisting preferably of the journals d d.
- These rest in suitable boxes or bearings, e 6, provided on the up per surface of the beam.
- a cap or bearing formed of a piece of plank or other suitable material, fitted in like manner to the journal, with its opposite end, f, in contact with the beam, and an intermediate bolt or bolts, 9, passing downward through both,with a nut, by which the necessary pressure is obtained to retain the journal in its seat.
- the rod is connected, returned to its seat, the bearer tightened, and the well is in pumping order at once.
- This method is very simple and convenient, not a single bolt or nut having to be removed.
- the head may be inverted and operate in the same manner.
- An adjustable clamp or coupling having an axis journal or journals, d d, for so connecting with the working-beam as to conform to the vertical position of the pump-rod during the oscillations of the beam, as set forth.
