To all whom, t may concern:
Ile it known tllat I, GEORGE ALLEN, of Franklin, in the county of Yenango and State of Pennsylvania, llave invented certain new and useful Improvements in Pumps for Oil- \Vells; and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enable others skilled ill-the art to which it appertains to lnakeand use the same.
My invention relates to an improvement in pumps for oil-wells, and more particularly to devices for automatically revolving the polish-rod or sucker-rod while the pulnp is ill operation. Itfrequently happens tllat the heavier parts of the oil settle on the rod, causing the latter to stick, and consequently seriously interfere with its free operation. lVhen this occurs, the rods have to be withdrawn and the adhering matter removed, and as some wells are several thousand feet deep the time and labor involved in cleaning the rods adds considerable to the expense of operating the well. It has been found that by giving the rods an occasional turn it breaks or disengages the parafne or adhering matter and the rod will work for a greater length ot time without removal for the purpose of cleaning same; and the object of this invention is to provide devices for automatically giving the rod a part rotation at each movement of the walking-beam; and it consists in the parts and combinations of parts, as will be more fully described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view in side elevation of a portion of a pump embodying my invention. Fig. 2 is a plan view of the rod-actnating devices, and Fig. 3 is aview in vertical section through the upper end of the rod.
A represents an upright post carrying at its top the walking-beam l5, which latter is vi brated by the pitman C and crankshaft C and actuates the rod D. 'lo the fl'ee end of the beam B is secured a metal plate E, provided at its front edge, at a point preferably midway between its ends, with a spherical enlargement a, which latter projects equally above alld below the plate and is provided with open vertical slot b, extending from its outer edge to a point equal to one-halfthe diameter of the rod D beyond the center'ot' the enlargement of This brings the polish or other l'od D directly in the center of the sphere when the parts are assembled. The polish or other rod D is properly adj usted and secured to the plate E by the sleeves G and G', the former o f which is secured to the polish or other rod D at a point above the sphere a, while the lower one G is secured to the rod below the sphere. end a socket g, shaped to conform tothe shape of the sphere, and hence it will be seen that when the sleeves` carrying the sockets are assembled on the rods, with the sockets g in contact with the upper and lower sides of the spllere, a ball-and-socket joint is formed which permits the rod to have free play'r"move ment. The sleeves are sccllred to the rod by set-screws c, and hence can be easily and quickly applied and adjusted as necessity de mands. One of the sleeves, and preferably the upper one G, is provided with a ratchetwheel ll, cast integral with the sleeve or rigidly secured thereto and engaged by the pawls I and I', the former of which is a spur for ellgaging the teeth of the ratchet, while the latter is provided with a hook adapted to engage the teeth. The pawls are located on opposite sides ofthe ratchet and are held in contact with samey by springs (Z. The rod D moves vertically while the walking-beam vibrates, and hence it follows that as the end of the walking-.beam carrying the rod moves upwardly the ratchet-wheel II is lnoved slightly away from the pawls and as the walking-beam moves downwardly the wheel approaches the pawls, and as one pawl is provided with a spur end adapted to engage the teeth and push saine forwardand the other with a hook it follows that as the wheel moves toward and away from the pawls it is engaged first byl one pawl end then by the other and given a slight rotary motion by each. The center of lnotion of the polish-rod is the sphere and as the wheel is several inches above the sphere it follows that on the downstroke of the walkillg-beam the wheel moves toward the pawls and is given a sligllt turn by pawl I and as it nloves away froln the pawls on the upstroke the hook-pawl I engages the teeth and holds the circumference of the wlleel, while the center thereof is carried forward. This gives the Wheel another part tllrn in the same direction,
Each sleeve carries at onel and so on indenitely, thus preventing the adhesion of paraiiine to the rod from interfering with the free operation of the rod.
Sucker-rods are made in sections, and from 5 twenty-live to seventy-five of these sections are used in each well. 'lhese rods freqnently come unscrewed while working, causing oonsiderable trouble to getthein ont. Aslovg rof4 tation in the direction that they sc revir toro gether would prevent this entirely. Again, where the rods do not rotate portions of the rods, generally at the enlarged metal joints, move constantly in one place against the inside of the tubing and in a short time Wear' 15 through the tube. A revolution of the rods willdistribnte this wear all around the inside ot the tubing, and thus prevent serions in- Jlliyy I can, if so desired, 'einploy this device in zo connection with` drills and other devices llaving a vertical moyen-ienl; and a slow rotary moven'lent, and hence I would have it linderstood tliatI do not confine its application to Pumping apparet-11S, 110i d0 I liiiiii myself te 25 the constretions shown and described, but
