W 11 at 00 co FRANK W. SHIREY AND JOHN W. DODD, OF TULSA, OKLAHOMA.

ROPE-SOCKET.

Application filed March 17, 1916.

To all whom it may concern:

Be it known that we, FRANK TV. SHIREY and JOHN W. Donn, citizens of the United States, residing at Tulsa, in the county of Tulsa and State of Oklahoma, have invented new and useful Improvements in Rope- Sockets, of which the following is a specification.

This invention relates to rope sockets, and it is an improvement on the device of this class for which Letters Patent of the United States, No. 1,061,134, were granted to us on May 6, 1913..

The present invention has among its objects to simplify and improve the general construction; to lessen the cost of manufacture; to provide for the easy and convenient assembling and disassembling of parts; and to enable a heavier spring to be used than is possible by the construction now usually employed.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same con sists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawing,--

Figure 1 is a side elevation of a rope socket constructed in accordance with the invention.

Fig. 2 is a sectional view taken on the line 22 in Fig. 1.

Fig. 3 is a transverse sectional view taken on the line 33 in Fig. 2.

Fig. 4 is a transverse sectional view taken on the line 41 in Fig. 2.

Fig. 5 is a vertical sectional View of the mandrel or plunger detached.

Corresponding parts in the several figures are denoted by like characters of reference.

The body 15 of the improved rope socket is provided at its upper end with an externally threaded neck 16 and at its lower end with a tapered internally threaded socket 16 which is adapted to receive the correspondingly threaded extremity of a drill tool or 'pering bore of the mandrel.

Specification of Letters Patent. Patented Rial. 19, 1918.

Serial No. 84,868.

a reducing sub or the like. The body 15 has a longitudinal bore extending through the entire length thereof, the upper end portion of said bore being of relatively small diameter, as indicated. at 17, while the lower end portion which extends through the greater portion of the body is of relatively large diameter, as seen at 18. The enlarged portion 18 of the bore"communicates with the threaded socket 16. The walls of the socket are provided at diametrically opposite sides with vertical slots 19 which communicate at their inner ends with the enlarged portion of the bore at the lower end of said enlarged portion but above the threaded socket portion.

A cylindrical mandrel or plunger 20 is fitted to slide in the enlarged portion 18 of the bore, said mandrel having a short neck 21 at the upper end thereof. The said mandrel is formed with a tapered bore 22 ex tending longitudinally therethrough, said bore being intercepted near its lower end by i a transverse slot 23 which is adapted to register with the slots 19 in the opposite sides of the body portion 15. The mandrel 20 receives the lower end portion of the rope or cable 2 1 which is babbitted or otherwise fixed in any well known manner in the ta- The mandrel is connected with the body member 15 by a key 25 which extends transversely through the slot 23 of the mandrel the end portions of said key being disposed within the slots 19, the cable being thereby prevented from twisting or turning with respect to the socket member while the socket member carrying the tool is free to move longitudinally with respect to the mandrel and the cable. A strong coiled spring 26 is placed in the enlarged portion 18 of the bore within the socket member, said spring abutting at its lower end on the mandrel and at its upper end on the shoulder 27 formed at the junc ture of the large and small portions of the bore. The body portion 15 of the socket member is provided near its lower end with flattened portions or recesses 28, said fiattened portions serving to form a convenient seat for a wrench or other tool by means of which the socket member may be held against rotation while the tool, which is not shown, is connected with the threaded socket provided for its reception at the lower end of the body.

In our former patent, hereinbefore refruitful source of annoyance.

ferred to, the mandrel or plunger is provided with a reduced portion or neck of considerable length, the same extendingthe socket member into slots extending entirely through the side Walls of said socket member, the construction is simplified and cheapened, and the work of assembling or disassembling the parts Will be much reduced. I It may be stated that by practical experimentation the improved device herein described has been found to be thoroughly useful and eflicient for the purposes for Which it is provided.

When the improved rope-socket is used in starting a Well it is preferred to remove the key '25, thus Permitting the cable to rotate to keep the line from kinking in running Copiei 0! this patent may be obtained for five cents each, by addressing the Commissioner of Patents,

oft slack in the rope. The key may be subsequently restored to its position as herein described. I

Having; thus described the invention, What is claimed as neW,'is: v

In a device of the class described, a cylindrical body member having a bore, the upper end of which is reduced to form a shoulder or offset, said body member having slots extending through the side Walls thereof, a mandrel operating in the large portion of the bore, a cable extending through the reduced portion of the bore and connected s'ecurely/With the mandrel, a removable key extending through the mandrel into the slots in the Walls of the body member, and a spring coiled about the cable and abutting at one end on the mandrel and at the other FRANK W. snrnnr.
