WRE-LIN-ROPE SOCKET.

Speclcation of Letters Patent.

v.Application led April 8, 1913.

Patented Sept. 1e, 191e Serial No. 759,754.

To all whom t may concern.' Be it known that I, JOSEPH BURNS a c1t1- zen of the Unitedl States, and resident of (kmuIgee, in the county of Okmulgee andy State of Oklahoma, have invented certain new and useful Improvements in Wire-Line- Rope Sockets, of which the following is al upper extremity thereof bearlng against specification.

One object of this invention isv to provide an etlicient swivel rope socket for well tools' -wherein theswivel is easily accessible and,"y from which `water and sand may readily clear.

A further obje-ct is to provide an im-A proved abutment Withinthe socket body for the -'lower' end of the swivel head or mandrel; also to combine with such abutment-a means for obstructing the opening of the body through which the swivel head is en-` tered.

In the accompanying drawings, Figure 1 is an elevation of a rope socket constructed in accordance with the invention, and Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a sectional plan taken on*` line 3-3 of Fig. 2. Fig. 4 is a detail of the abutment-forming device entered in the socket body. Fig. 5 is an elevation, and Fig.

6 a vertical section similar to the upper portions 'of Figs. 1 and 2, respectively, illustrating an abutment-forming device of modified form. Fig. 7 is a detail of the modified abutment.

. Referring to the drawings, 2 designates the body of the socket which is formed at its lower end with the usual threaded boX 3 for receiving the tapered pin carried by the upperextre'mity of all socket-supported well tools.- Body 2 is formed with the vertical cylindrical cavity v4 which for convenience of manfacturemay consist ofan upward extension of box 3, the cavity eX- tending well up toward the upper end of the body and with a rope passage 5 eXtending from the 'upper end of the cavity through the upper extremity of the body.

Cavity 4 and passage 5 are concentric with,

shoulder or abutment 6.

A portion of the length of cavity 4 .is

i open laterally through the side of the socket body as indicated at 7,",.the upper end of this lateral opening being in a plane lower than abut-ment 6, and entered through open- 4 ing 7 is the cylindrical head or mandrel 8, which has a turning fit in cavity 4. Head 8 is vformed with the upwardly tapering bore 9 to confine the knotted extremity 10 'of cable 10, the latter'extending into the lsocket body through passage Part V8 Vis in eiect a swivel head for the cable, the

shoulder v6, with socket body 2 adapted to turn or swivel thereon, as will be understood.

Entered through lateral opening 7 is device 11 which vlits cavityv 4, said devicel being of plug form with the lower portion 11- thereof extending. downwardly into cavity 4 beneath inlet passage 7. Lateral extension 12 ofpart 11 fits the lower portion of' outlet passage 7 and so contracts the latter as to prevent swivel head 8 from loweringsufiicient-ly to pass outwardly therethrough, the upper portion of'passage. 7 being spaced downwardly from abutment y6 so that bore 4 extends above said. passage, as indicated at 4 i Fitting a socket 13. in one side of part 11 is pin 14 whichis held normally projected by spring 14.,`with the pin adapted to 'enter cavity 15 in the wall of bore 4, thus locking 4part 11 in position therein. Passage 15 is reduced in size and extended to the outer face of socket body 2, as indicated at 15', so that a set or like device may be introduced for retracting the pin when part 11 is to be released and removed.

The vertically movable swivel head or mandrel 8 may be utilized for jarring the socket, part 11 providing an effective abut' ment for receiving the down strokes, and as said part fits closely Within the -socket bore the ,force of the blows is communicated through extension 12 tothe socket body. The purpose of such jarring is well understood'in the art, and need not be explained in detail.- r l In the adaptation shown in Figs. 5, 6 and 7, lateral extension 12 of the abutment- :forn'iing.party 11 is, formed with t-he upward horn-like 4extension 16 which-substantially closes passage 7, there being suiiicient clearance,*however, as indicated v'at 17, between the side faces of said extension and the walls of the passage to permit sand and water to escape from the swivel chamber, so that the tool is self-cleaning a's to any sand and water that may enter the swivel by passing downwardly along'cable 10.

ywell tools and at its upper endv formed with a cable inlet passage, the body formed with a cavity beneath said passage with said cavity open laterally, a head within the cavity and smaller than the lateral opening and adapted to pass therethrough and be secured to a cable entered through the cable passage,and means secured within the lateral opening for obstructing outward movement of the head.

2. The combination of a rope socket body adapted at its lower end to connect with well tools and at its upper end formed with a cavity open laterally, a head within the cavity and smaller than the lateral opening and adapted to pass therethrough, the upper portion of the body formed with a cable 4passage with the head adapted to be seity, the head being smaller than the lateral cui i to a cable entered through the passage, and a device removably entered in the body cavity and extending into and partially closing the lateral opening, said device. limiting the downward movement of the head and preventing out-ward movement thereof through the lateral opening.

3. The combination of a rope socket body adapted at its lower end to connect with well tools, the body formed with a laterally open swivel-head cavity and also open to admit a drilling cable, a swivel head within;

the cavity and secured to the cable extremnpening of the cavity and adapted to pass .inwardly and outwardly therethrough, an abut-ment device smaller than the lateral opening and adapted to pass inwardly and outwardly therethrough, said device having a plug-like portion fitting the body cavity beneath the laterally open portion thereof, the abutment device having a side extension lying' within and obstructing the lateral opening, the abutment device preventing removal of the swivel head, and means for removably securing the abutment device in position. l

4. The combination of a rope socket body adapted at, its lower end to connectwith well tools and at its upper end formed with a cavity open 'laterally through a face of the body, a head adapted to be entered in the cavity through the lateral opening, the upper portion of thebody formed with a cable passage with the head adapted to be secured to a cable entered through the passage, an abutment-forming device within the body cavity and adapted to be engaged by the head when in lowered position, and a normally projected spring-actuated pin carried. by the abutment with a wall of the body cavity formed with an opening adapted to receive the pin.

5. The combination ot a rope socket adapted at its lower end to connect with well tools' and at its upper end formed with a cavity open laterally through a tace of the body, a head adapted to be entered in the cavity through the lateral opening, the upper portion of the body formed with a cable passage with the head adapted to be secured to a cable entered through the passage, an abutment-forming device within the body cavity and adapted to be engaged' by the head when in lowered position, and a normally projected spring-actuated pin carried by the abutment-forming head, the body formed with a. pin passage extending to its outer face which is adapted to receive the spring-projected pin and also adapted to form a passage :tor a pin-retracting device when the head is to be released.

6. The combination of a rope socket body' adapted at its lower end to connect ivi-th well tools, the body formed with a bore extending upwardly rom its lower end and with the upper end of the body formed with a cable entering passage which communicates with the bore, the body formed with a lateral outlet passage communicating with the upper portion of the bore, a head adapted to be entered in the cavity through the lateral opening and adapted to be secured to a cable, an abutment forming device eX- tending downwardly into the bore beneath the lower end of the lateral passage, and an extension on said device lying within and adapted to obstruct the lateral passage.

In testimony whereof l affix my signature in presence of two witnesses.
