HARVEY R. STANDLEE, or TULSA, OKLAHOMA, ASSIGNOR TO THE GUIBERSON coRronA- TION, or DALLAS, TEXAS, A CORPORATION or DELAWARE OIL sAvnn Application filed October 28, 1929. Serial N6 102,851.

This invention relates to new and useful improvements in oil savers. V I w One object of the invention is to provide an oil saver for use on drill cable, rod and the like in connection with oil and gas wells, whereby certain advantageous results are ob tained.

A particular object of the inventionis to provide improved packing means for embracing a cable or other cylindrical member together with simple and positive packing compressing means including elements working with sufficient leverage to exert ample pressure to quickly compress the packing against varying head pressures.

A further obj ectof the invention is to provide a packing and a guide arranged for,

ready application to and removal from the cable or other vertically moving member, and involving simple and easily worked parts.

Another object of the invention is to provide an oil saver having its seal packing below its supporting flange, whereby the length of the device is shortened which permits the temper screw to be screwed further down before reclamping a cable.

A still further object of the invention is to provide an oil saver in which the adjustable packing may be quickly and conveniently replaced. A

Another object of the invention is to provide a packing member of peculiar construc tion arranged to equally grip a cylindrical member throughout the length ofsaid pack ing member and having adjustable means for feeding said packing member to the cylindrical member as it wears.

Animportantobject of the invention is to provide an oil saver having adjustable packing means of a minimum number of working parts of rugged construction, thus providing for efficiency and speed in operation.

A construction designed to carry out the invention will be hereinafter described together with other features of the invention.

The invention will be more readily understood from a reading of the following speci- [ication and by reference to the accompanying drawings in which an example of the invention is shown, and wherein Figure 1 is a side elevation of ran oil saver constructed in accordance with the invention and illustrated as applied to a cable,

Inthe drawings the numeral designates a split housing. The housing includes a re movable lower member 10' secured thereto by bolts 11 and nuts 12. The bolts 11 are mounted in flanges 13 extending from. a reduced neck 14 of the housing. Suitable packing strips (Figure 4;) are interposed between the housing members. I

The housing includes an upper packing chamber A immediately above the reduced neck 14, and a lower packing chamber B. A

ing against upright shoes 19. The shoes (Figure 16) have their rear faces flat to receive the blocks and their front faces concaved to embrace opposite sides of a cylindrical packing member or sleeve 20 fitting in the lower chamber.

Adjusting screws 21 (Figure 13) are threaded through the flange at the same angles as the walls of the guides 17. Each wedge block 18 (Figures 2 and 12) has a key slot 22 for receiving the lower end of one of the screws 21, whereby the blocks are suspended in the guides. By rotating the screws clockwise the blocks are slid downwardly and inwardly thus displacing the shoes 19 inwardly and compressing the packing sleeve about the cable, rod or other element which passes through the device.

The neck 14 has a reduced opening 23 through which the cable C passes and thus said neck forms the top of the lower packing chamber, whereby the sleeve 20 is retained. The upper packing chamber A has cheek plates 24 with opposite horizontal slots 25 for receiving and supporting lugs 26 of followers 27. The lugs slide in the slots and have their outer ends reduced and rounded to form pins 26 for the pivoting thereon of links 28 which have their opposite ends pivoted to levers 29. The levers are pivotally mounted on each side of the housing at the center of the cheek plates on screws 53. The links are pivoted to each lever on opposite sides of its center and so positioned that when each lever is swung upwardly the followers are drawn inwardly toward the center of the housing and the cable G.

The followers 27 are provided with upright dove-tailed grooves 30 for receiving therein a dovetailed rib 31 (Figures 9 and 11) of a rectangular packing block or member 32 (Figure 8). The packing block is formed of rubber or any material suitable for the purpose and has a concave vertical face or seat Grease pockets 33' may be provided in the face 33.

It is obvious that the inward movement of the followers will clamp the packing blocks about the cable and by the location of the lugs 26 at the center of the followers 27 the inward pressure will be evenly distributed to the packing blocks causing said blocks to antomatically adjust themselves for equal gripping of the cable throughout its length.

A removable guide block .34 is set into the top of the housing on the same side as the removable section 10 and provides for the con- Venient, easy and quick application of the device to and removal from a cable rod or the like. The removable guide block 34 rests'on shoulders 35 of the housing and has a tongue 36 (Figures 15 and 18) extending down between the cheek plates to the top of the chamber A, thus forming a top guide for the follower and packing. The shoulders and the tongue 36 are provided with an opening 37 for the insertion of a bolt 38 there through and on which a nut 38 is screwed for securing the block to the housing.

A guide roller 39 is mounted in a recess 40 of the block 34 on a shaft 41 secured in said block. A similar guide roller 39 is mounted in like manner in a recess 40 of the housing, directly opposite and in horizontal alinement with the recess 40. Recesses 23 are also provided in the block and housing for the passage therethrough of the cable 0 which is guided by the rollers into the housing.

Segmental gears 43 are mounted on the levers 29 and are swung by pinions 44 fastened on the opposite ends of a shaft 45 journaled in a yoke 46 extending laterally from the top of the housing. A Worm gear 47 is fastened on the shaft 45 Within the yoke. A worm screw 49 (Figure 2) meshes with and drives the gear 47 and is journaled on a stud 50 screwed into the housing above the yoke.

A hold down keeper 51 secured to the yoke bridges over the hub of the worm screw 49 and a crank handle (Figure 1) 52 engages on the angular end of the screw for revolving the same'on the stud 50 and thus operating the gears 43. The segmental gears each have their teeth terminating so that when the pinions 44 engage in the uppermost teeth the parts will'be locked against further movement except in a reverse direction, thus holding the followers against accidental displacement from within the chamber A.

It is obvious that by revolving the crank handle 52 the shaft 45 is rotated and the segmental gears are swung and as they are swung the links pull the followers inwardly, thus compressing the packing against the cable C. After continued use and when the pinions reach the lowermost teeth on the segments, the packing will have been completely worn out and further inward movement of the followers will be prevented. The open 110 ator will thus know that the packing must be replaced. I I

When it becomes necessary to replace the upper packing 32 it is merely necessary to remove the screws 53 to displace the levers 29 115 and the links 28 thus leaving the followers free for removal from the housing and for renewing the packing in the followers. In replacing the upper packing the parts are manipulated to bring the segmental gears to 120 the position shown in Figure 1.

It will be seen that by reason of the worm gearing and comparatively large segments considerable leverage is had and therefore the levers 29 will compress the packing 32 with 125 ample force. The device may be easily and quickly operated and as it is only necessary to handle five bolts (38, two 11s and two 53s) the saver may be quickly mounted or dismounted.

Various changes in the size and shape of the different parts, as well as modifications and alterations, may be made within the scope of the appended claims.
