TUBING OIL SAVER.

Application led June 16, 1926. Serial No. 116,348.

This invention relates to improvements in tubing oil savers.

The object of this invention is to provide a device of the type described of simplified, reversible construction, with a packing element of sutlicient flexibility to permit the passage of tubing joints and at the same time form packers of the oil seal type.

Other objects will more clearly hereinafter appear by reference to the accompanying drawings forming a part of this specilication, and wherein like reference numerals designate corresponding parts throughout the several views, in which:

Figure 1 is a side elevation, partly in section, showing the tubing in dotted lines;

Figure 2 is a side elevation of one of the vertical sections comprising the oil saver;

Figure 3 is a top plan view of a packer element partly broken away;

Figure 4; is a side elevation of a packer section and shows clearly a packing rubber; and

Figure 5 is a top plan view.

Heretofore in the art it has been necessary in utilizing control head elements and packer elements adapted for application to the conventional control head of an oil well, to provide a different unit for wells of different diameters. The majority of control heads at the present time in use are of two standard sizes, and the construction of the present oil saver body includes, as will hereafter more clearly appear, flanges of two sizes for connect1on to the control heads. Obviously from this, the same tubing oil saver is adaptable to oil wells of the two standard sizes. In the present illustration, the oil saver comprises a body formed of two vertical half sections A and B, centrally enlarged as at a, b, to form a chamber for the reception of the packing rubbers and operating mechanism.

The flanges D, D', formed at the upper and lower ends of the casing are of ventional construction and differ only in that they are of dilerent diameter, the measurement corresponding to the standard measurement at present in use.

Figure 2 shows a side elevation of one of the vertical sections comprising the tubing oil saver and in this illustration the shape and arrangement of the chamber will e conseen. In cross-section the chamber is substantially rectangular in shape, whereby the walls form a more substantial and accurate guide means for the rubber and the rubber casing. The communicating passages from the central chamber are formed of diverging walls C, the diameters of which gradually increase outwardly, thereby forming tapered sockets of identical formation for the rece tion of the usual slips, not shown. The object of this arrangement is to permit the reversing of the oil saver and the use of the same slips at both ends of the structure. The adjacent edges E of the oil saver sections are flanged outwardly at spaced points and bolt holes e are formed in such flanges for use in assembling. The outer walls of the central chamber are formed with diametrically arranged central openings F for the reception of the plugs f through which the adjusting levers G operate. These plugs are threaded into the wall openings and are formed with central threaded o enings g for engagement with the threade portions of the levers G. The levers are provided with restricted neck portions H and the enlarged head portions h. which engagel Within the pockets J extending outwardl from rubber backing plates to be hereina ter described. These pockets J are formed of u per and lower walls, j, j', respectively, tlie upper walls being bent downwardly to form flanges j which act as stops to limit the movement of the lever extremities. An examination of the drawing will disclose the fact that the space between the lower wall and the flange portion of the upper wall is insuilicientto permit the escape of the lever extremity when the lever is in horizontal position, which position is normal when the parts are assembled.

While it is common in the art to provide rubber packers for tubing and wire line oil savers of such a character as to permit the passage of an enlargement on the wire line or on the tubing without the necessity of manually expanding the rubbers, the present rubber construction creates an additlonal function in that it provides a rubber of the oil seal type shown applied to a wire line in the Heggam Patent #1,256,899. This oil seal is formed by the series of s aced slots in the engaging face of the rub er, which slots after slight usage, become gummed with a hardened rubber condensate which has even greater scaling capacity than the rubber itself. In the rubber packer L utilized in the present oil saver, two sections are provided, each shaped to snugly fit within a chamber section and provided with a backing plate M. The backing plates are flanged inwardly at m to seat in grooves formed in the opposite faces of the rubber sections and are provided with the pockets J for the lever extremities as heretofore described. The meeting faces of the rubbers are grooved or cut away to jointly form a central passage which, when the rubbers are seated and positioned within the oil saver body, form a. continuation of the passage through the latter for the reception of the tubing. The adjacent longitudinal edges of the rubber packer elements are formed with oppositely arranged, elongated slots N which extend substantially beyond the outer sealing rings or slots heretofore mentioned and function in the same manner to seal these faces. Attention is directed to the fact that the distance between the slots P which engage the tubing is substantially identical in each instance and to provide this arrangement for the end slots the ends of the sectionsare bevelled as at Q, thereby reducing the axial measurement of the. material l'orming the rings outwardly of the end slots. The arrangement'shown and described produces a sealing effect heretofore unknown in the art and which cannot be obtained by the use of separate Aspaced rubbers and like assemblies. The present rubber produces substantially aunit structure, the vertical and radial joints of which are oil sealed and the entire body is flexible and adjustable to irregular bodies.

longitudinal passage in said body, the walls of said passage only in said rubber being slotted to provide spaced flanges, and the adjacent'walls of the rubber sections being slotted to form sealing chambers when the adjacent faces abut and meansl for adjusting the packer removably supported by the body sections.

3. The substance of claim 2 characterized in that the outer flanges formed inthe walls of the. passage in said rubbers are spaced inwardly from the rubber extremities and the outer faces of the outer iiangcs diverge outwardly to form guiding means for the tubing. Y

4. The substance ot' claim f2 characterized in that the rubber sections are provided with backing plates which assist in positioning the rubber sections within the chamber and also provide attaching means for the adjusting` levers, which latter are carried by removable plugs threaded into openings in the sectional body.

In testimony whereof I ailix my signature.
