Application filed December 14, 1922. Serial No. 606,990.

Tojall whom it may concern:

Be it known that 1, JOHN D. Russ, residing at Spencer, county of Roane, State of West Virginia, post office address Spen- 6 cer, West Virginia, a citizen of the United States, have invented certain new and useful Improvementsin Releasable Wire-Rope Sockets, of whichthe following is a specification.

The object of my invention is to design areleasable wire-rope socket for use in connection with oil-wells, which presents a form "of Construction greatly simplified over those shown, for instance, in my prior United States Letters-Patent Nos. 1,409,066 and 1,409,067, granted March 7, 1922, and in United States-Letters-Patent No. 1,190,345,

granted July 11, 1916, to J. J. Varner, of

which I am the assignee of an undivided one-half interest.

With this object in view, the invention resides, broadly stated, in a two-part unit, the sections of which are mortised to provide complemental and mating 'tenons, means for normally holding said sections in assembled relation, against separation, ineluding a spring-pressed latch, and means for moving said latch, against the influence of its spring, to unlocking position, to per- ::0 mit separation of said sections.

The invention will be described more in detail hereinafter, in connection with the accompanying drawing, forming part of my specification, in which, briefly described,

,Figure 1 is a view in side elevation of my device;

Figure 2 is a sectional view on the section line 2-2, Figure 1;

Figure 3 is a view in perspective of one of the sections of the unit; and

Figure 4 is a view in perspective of the other section.

Referring now in detail to the drawing:

1 and 2 designate the two sections of the unit, which may, appropriately for the purpose for which they are intended, be of suitable metal, such as iron. Each section is mortised or cut away to provide a tenon 3. In the assembledrelation of the two sections, the flat faces of the tenons are placed together, as shown in Fig. 2, so that, exteriorly, the unit presents a cylindrical appearance, but, of, course, the unit may be square, or other shape, in outline, if desired.

The tenon 3 of the section 2 is provided, on its fiat face, transversely thereof, with a groove 4 to receive a roller 5 seated in a transverse groove in the fiat face of the tenon of the section 1. If desired, the roller 5 may be integral with the tenon of the section 1, as would, be practical if the sections are cast in a mould, or the roller may be welded in the groove of the section 1.

The section 2 carries a tooth or dog suitably secured in a recess therein, or the dog may be integral with the section 2, as is practical if the section is cast in a mould, or the dog may be welded to the section 2. The dog, in the assembled relation "of the sections 1 and 2, projects into a recess 7 in the free end of the tenon '3 of the member 1, as shown in Fig. 2.

Seated in a recess8 in the free end of the tenon 3 of the section 2, and normally projecting, at one end, out of said recess, is a latch, 9, in the form of a plunger-pin, which is urged in one direction by a coil spring disposed between the inner end of said latch and the inner end of the recess 8. In the assembled position of the sections 1 and 2, the latch projects into an opening 11 in the member 1/ A piston 12 carried by a stem 13 slides in the opening 11. The 'exterior endofthe stem 13 may be provided with a button or head 14:, in the path of movement. of a weight 15. The stem 13 reoiprocates in a central aperture provided therefor in a plug 16, which is screwed into the upper end of the recess 11.

The section 2 may be provided laterally with a, threaded recess 17 for connection with the ordinary sinker-pin, and the section 1 with a threaded boss 18 for threaded connection with a tubular sleeve: or socket-piece 19, in which one end of a wire rope is received and secured in a well known manner.

The assembled position of the sections 1 and 2 is as shown in Fig. 2, where it is noted that the sections are locked against accidental separation. In an emergency, when the sinker-pin becomes anchored or stuck and can not be disengaged, the operator places the upper end of the wire rope, which is secured at its other end in the sleeve or socket-piece 19, and the weight slides, by gravity, ,down the rope until it contacts with the button 14, thereby driving the plunger 12 against the latch 9, and moving the latter inward, against the influence of its spring 10, so that the latch is forced out of the recess 11 in the member 1. Thereupon, an upward pull on the wire rope will cause the roller 5 to ride out of the recess or groove 4; whereupon the section 1 becomes entirely detached from the section 2, and the wire rope, intact, may be pulled out of the well.

When the structure is analyzed, it will be seen that the roller 5 is an indispensable element of the locking-means, the latch 9 being the other indispensable element thereof. The roller 5 functions to prevent independent movement of one section 1 or 2, relative to the other, in the direction. of its length, when the latch 9 is in locking position; and the latch 9 prevents sidewise movement of one section 1 or 2, relative to the other. The tooth or dog 6 is not indispensable, but is advantageous, since it functions to relieve the latch 9 of some of the strain which would otherwise be placed upon it, if said dog were not provided, and, in practice, has been found very efficacious for the purpose intended.

Having thus fully described my invention, what I claim as new and desire to secure by Letters-Patent is:

1. A wire-rope socket device comprising two members, mortised to provide mating tongues, means for normally holding said members in assembled position with said tongues disposed face to face, said means comprising a roller carried transversely of one tongue and normally engaging the other tongue, and a spring-pressed latch carried by one member and normally engaging the other member.

2. A wire-rope socket device comprising two members, mortised to provide mating tongues, means for normally holding said members in assembled position with said tongues disposed face to face, and includmg a spring-pressed latch carried by one member and normally engaging the other member, and a latclrmovimg element in alinement with said latch.

3. A wire-rope socket device comprising two members, mortised to provide mating tongues, means for normally holding said members in assembled position with said tongues disposed face to face, and including a springpressed latch carried by one memher and normally engaging the other memher, a latch-moving element in alinement with said latch, and means for actuating said latch-moving element to unlock said latch.

4. A wire-rope socket device comprising two members, mortised to provide mating tongues, means for normally holding said members in assembled position with said tongues disposed face to face, and including a spring-pressed latch carried by one memher and normally engaging the other memher. a latch-moving element in alinement with said latch, and a weight for actuating said latch-moving element to unlock said latch.

5. A wire-rope socket device comprising two members, a spring pressed sliding pinlatch carried'by one member and normally engaging the other member, a latch-operating member in alinement with said latch, and means for actuating said latch-operating member to move said latch to unlocking position.

In testimony whereof I hereunto afiix my signature.

- JOHN D. RUSS.
