This invention relates to certain improvements in swivel jar sockets which are utilized in the construction or drilling of oil wells and the like and contemplates certain changes in the construction oij that type of socket shown in Letters Patentv Nos. 1,07 3,-

. 469 and 1,073,470, dated September 16, 1913,

.and No. 1,107,889, dated August 18, 1914,

and 1,045,883, dated December 3, 1912.'

In that type ot' socket shown in the Burns patents supra, a side hole arrangement is provided whereby the wirerope is introduced through the neck of the socket and out through the side hole. The arrangement of the side hole obviously materially decreases the strength of the socket and also permits the swivel escaping through same to become lodged between the socket and the casing. The construction of the'present device eliminates the foregoing objection andy also provides solid metal between the box oit' the socket'and the swivel which-provides a dry joint and prevents the battering of thepin.

In addition to the foregoing the present arrangement enables the examination of the swivel withoutthe breaking of the joint.

With the foregoing and other Vobjects in view attention is directed to the' following speciiication and claims and particularly to the annexed drawing wherein like numerals of reference designate corresponding parts throughoutthe several views in which:

Figure 1 is a side elevation with parts v chamber to permit suici ent play for the pasbroken away insection.

Figure 2 is a vertical sectional view through the upper portion of the socket with the parts' seated in position.

Figure 3 is a top plan view.

Figure4 is a section on line 4-4 ure 1.

Figure 5 is a side elevation showing a modified form of slips utilized where a swivel action is not desired, and i Figure 6 is an end view o'same..

In the present illustration the socket body i 1 is of conventional shape including the lower internally threaded box 2 tapered up- Wardly to receive the tapered-threadedr end of a stem or the like. An axial cylindrical bore 3 extends from the upper endY of the socket body downwardly a sulicient distance to accommodate the cable swivel movement. The chamber formed by the axial bore 3 is of Fig `drained by the pertoi'ations 4 arranged 'in suitable series aslniay beffound necessary.

A swivel headr 5 is arranged to carry the cable extremity andis positioned normally vithin the chamber formed ybythe' bore' 3. This bore may be of gradually reduced diaineter upwardly throughout its entire length or'only fory a portion of its length at the upper end to'perinit engagement of the locking means for the swivel. This means comprises a sectional rusto-conical hollow slip 8, each section of which is substantially identical, and it is oi. such formation as to create when assembled a tapered slip as more clearly shown in `Figure 2. In the present illustration they slip body 8 merely comprises two sections whichwill be'found suiicient in the usual conventional structure. The upper extremities of the y.slip sections are formed with 'openings 9 to receive a wedge or other ytool which may be necessary iny releasing the parts. n

In actual use kwhen assembling a socket the swivelfwhich has' previously been babbitted on theV line is introduced through the neck of the socket until the upper extremity of the swivel is rbelow the upper end of the socket. The first 'half of the slip, in the event that saine merely 'comprises two sections, is seated on top ofthe swivel and the entire arrangement is lowered into the center pf the spcket until the top of the slip section is sufficiently within the gradually enlarged sage and positioning of the next section. In the event 'that the chamber is formed Awith an internal shoulder to engage the slips then the first slip section can be lowered below this shoulder before `the second is placed adjacent thereto. Obviously the manipula `tion of the various parts will be without broken by inserting a wedge or the like `into i the opening formed in one section and resting the wedge on the upper edge of the socket body to prevent inward movement ot Said Section, while the other section can be driven into the chamber.

it frequently happens that the operator does not want to swivel and in` this event the swivel can be eliminated and the slips shown in Figures and G utilized. lili/Then i these slips are used without the swivel the end of the cable located within the slips may 'ue enlarged, incr xesed in size or knotted in any desired manner so not to be withdrawable through the slips.

The present coi friction subject to numerous minor changes in details suoli as well tools and at its upper end formed with a concentric elongated chamber having; a tapered wall portion, swivel, and a y*clip closingl said chamber comprising a tubular *sectional body having a tapered outer face for engagement with the tapered wall portion of said chamber, the sections ot the kslip being provided with opeuin's aceefsible from the upper end of the socket `for engaging a releasing tool.

2. The combination with a rope soci-iet body formed with an axial bore extending downwardly from the upper end with the upper portion otl saidbore tapering upwardly, a` swivel head for the extremity of a cable arranged in said bore, and a tubular slip for closing said bore, said slip being formed of a plurality ot tapered sections and at least one oil the sections being provided with au opening` acc l,sible from the upper end of the socket for the reception of a releasing tool.

3. The combination with a rope socket body formed with an axial bore extending downwardly from its upper end with the upper portion of said bore tapered upwardly, a swivel head for the extremity of a Cable arranoed in said borej and a tubular slip for Closing said bore, the said slip being -formed of a plurality ot sections: which are pi video with openi* v i accessible Ytrom the upper end of' the socket for engagV5 ng a releasing tool.

The combination with a rope socket bot-.y formed with an axial bore opening' through its upper end and sectional means wedged in said bore for holding the er:- tremity ot' a cable secured to the socket body, Said sectional means having at least one of its sections formed, at a. point enteriorly of the seclret, to receive a releasing tool.

5. The combination with a rope socket body ormed with an axial bore opening through its upper end, a swivel head tor the extremity oi a cable arranged in said bore and means secured in the bore and loosely bearing' againstthe outer end ot the swivel head for preventing` the withdrawal ot the latter; the said socket body being formed with a series ot' perfor-ations communicating;- with the said bore and part of which are in transverse alignment with the normal po-r sition ot the swivel head, vand the said swivel head being` small enough in diameter so as not to fill the bore ot' ythe socket body and obstruct the said pertorations.

In testimony whereof ath); my `signature.

PAUL ARBON.
