ROPE-SOCKET.

l SPECIFICATION forming part of Letters Patent No. 761,396, dated May 31, 1904.' Application led July 22, 1903. Serial No. 166,611. (No model.)

To all whom t may concern.-

Be it known that I, CHARLES PETERS, a citi-- zen of the United States, residing at Nampa, in the county of Canyon and State of Idaho,

have invented a new and useful Rope-Socket, of

which the following is a specification.

This invention relates to devices for coupling" the ends of ropes to drilling-tools or other fixtures, and is applicable more particularly to well-drilling apparatus, but which may also be employed wherever it is desired to couple a rope'or cable to a chain or other device.

The invention consists in a tapered socket screw-threaded at its largerv end and carrying means for the attachment of the drill-tool at.

l specied in the claims following.

In the drawings illustrative of the invention, Figure 1 is a vertical section of the device.

Fig. 2 is a 'transverse section on thel'ine 2 2 for rotating it, whereby the head may be adjusted in the socket. Within the socket are disposed two opposing tapered segmental plates 1313, the two plates when combined forming a tapered divided sleeve, as shown. Extending from the interiors of the plates 13 13 are spurs 14, as shown.

The rope or cable is indicated at 15 and will beenclaspedat its end by the plates 13 13,

with the spurs extending into the. cable to firmly clamp it between the plates.

When the device is to be used, the head 12 will be passed over the end of the rope or cable and the plates 13 13 placed upon opposite sides of the end of the cable below the head 12. The plates 13 13 will not meet at their adjacent edges, as indicated in Fig. 2, so vthat when inserted into the socket with the cable between them and vthe head member screwed home in thesocket the plates will have ample room inwhich to be contracted around the cable when forced downward into the tapered socket. By this means the cable will be very iirmly clamped between the plates and rigidly united to the socket member.Y

While twoof the tapered plate members 13 13 are shown, I do not desire'to be limited to this number, as a change in this particular would not be a departure from the principle of the invention. l

The device maybe constructed tot anysized rope or cable andv willY form a very eilicient implement for the various purposes for which similar devices are-employed. -Its extreme simplicity and ease of application and great strength of grip will make it a very eflicient and valuable device.

Where ropes of smaller diameter than the socket are to be employed in connection therev with, I prefer to use an auxiliary sleeve l16,

which may beplaced within the head 12, and said sleeve is provided with a flange 17, extending under the head and engaging the plates 13 13. This is plainly illustrated in Fig. 3.

Having thus described my invention, what 'clamp members having inwardly-extending spurs to engage the cable, and a sleeve slidable on the cable and having an externallyscrew-threaded reduced end adapted to engage with said threaded socket and having a shoul- IOO der adapted to abut against the outer edge of the socket with the inner edge of its reduced end abutting against the outer edges of the elamp members to exert a longitudinal force upon said tapered clamp members to move them forcibly into said socket.

2. A clamp comprising a socket member ared toward one end, a plurality of clamping members having inwardly-extending cable-engaging spurs adapted to penetrate the Cable and hold said clamp members firmly in connection therewith, a sleeve loosely engaging
