RO PE- SOCKET.

SPECIFICATION forming part of Letters Patent No. 499,954, dated June 20, 1893. Application filed January 28, 1893. SerialNo. 45 1 lN mml l-l To all whom it may concern.-

Be it, known that 1, DAVID W. BLACK, of Butler, in the county of Butler and State of Pennsylvania, have invented a new and useful Improvement in Rope-Sockets, of which the following is a full, clear, and exact description.

The object of my invention is to provide an improved rope socket for use as a deep well tool and to avoid the disadvantages incident to former rope sockets, which have been difficult to apply and often impossible to free from the rope when it is desired to remove them.

To this end my invention consists in a rope socket having wedge slipsand a removable seat adapted to clamp the wedge slips on the rope, and means by which the seat is forced positively against the slips so as to press them against the rope and cause them to hold the same.

I will now describe my invention so that othersskilled in the art to which it appertains may manufacture and use the same, reference being had to the accompanying drawings, forming part of this-specification, in which- Figure 1 is a longitudinal sectional view of my improved rope socket as applied to the rope. Figs. 2 and 3 are detached views of the slips and removable seat. Fig. 4 is a longitudinal sectional view of a modification, and Figs. 5 and 6 are detached views of parts of the same.

Like symbols of referenceindicatelike parts in each.

In the drawings, 2 represents one of the parts of the socket, having at its lower end the usual threaded portion adapted to be engaged with other tools in the well, and having at its upper portion a tubular opening for the rope and an annular recess 3, having a seat 4,.

in which are seated the wedge-slips 5, which are of segmental conical form and may be of any suitable number, preferably three. On their inner sides they are preferably serrated so that they may hold the rope securely, and their upper ends are comically tapered so as to fit in the tapered seat of thefremov'able sleeve 6. This annular sleeve 6 may also be made solid or in segments corresponding to the segments of the wedge-slips 5, and it is provided at its lower end with the conically- .tapered seat 7, so that the sleeve may fit over and coincide with the tapered end of the slips 5. The upper part 8 of the socket is tubular "in form, and at its lower end is a screw-thread which fits in the thread in the recess 3 of the lower-portion 2 of the socket, so that when the two parts 2 and S'are screwed together, the end 10 of the part 8 will act as a follower and bear down on the sleeve 6.

The operation is as followsz-The rope 9 is passed through the tubular opening in the part 8 and inserted into the end of the part 2. The slips 5 are then inserted in the recess 3, on the seat 4, around the rope, and the sleeve 6 is placed in the recess over the tapered end of the slips. The upper part 8 of the socket is then screwed down in the recess 3 until it bears on the sleeve 6, sufficiently to cause the slips to bind on the rope so as to hold the same. When it is desired to detach the socket,

the part 8 is unscrewed, and on pulling up the rope the sleeve 6 and slips 5 are withdrawn from the recess 3, and being formed in segments they fall apart and from off the rope.

In Figs. 4, 5' and 6 I show a modified construction of the apparatus, in which the recess 3-is formed in the lower portion of the upper part 8 of the socket, and the follower is formed on the lower part 2 of the socket, and while thewedge slips 5 are the same in construction as in the other form of socket, they here occupy an inverted position and are compressed against the rope by the upward pressure of the sleeve 6 and the follower 10. On the upper part of the follower 10 is an annular collar 11, and on the inner face of the sleeve 6 is a corresponding annular groove 12, into which the collar 11 fits when the segments formingthe sleeve 6are placed around the follower.

The operation is as follows-The rope is passed through the part 8 and into the openthe recess 3 around the rope. The segments forming the sleeve 6 are then placed around the follower 10, the collar 11 fitting in thegrooves 12, and the follower is screwed into the recess 3 until the sleeve 6 compresses the slips 5, as already described. When it is demg in the part 2 and the slips 5 are placed in sired to detachth'e socketythc part 2 is imscrewed from the part 8, and as the'follower 10 is withdrawn from the recess 3 the sleeve 6 being connected with the follower is also withdrawn, releasing the slips 5.

The advantages oii my invention will be apparent -to those skilled in the art. The rope socket is simple in construction, and is not only easily applied, but is also easily removed.

I claim 1. A ropesocket having a tool connection, an opening for the rope, Wedge-slips havingin 1 clined outer surfaces, a loose clamping sleeve, having an interior inclined face and a follower; adapted to bear on: the s1eeve,s1'1bstanr 5 tially as described.

2. Arope socket having atool connection, an opening for the rope, wedge slips, a clamping sleeve, and a follower, the sleeve and follower being connected with eachother; substantially as described. I i e In testimony whereof I have hereunto set my hand.

DAVID W. BLACK.
