DANIEL W. SNOW, OF FILLMORE, CALIFORNIA.

WIRE-ROPE SOCKET.

T 0 all whom it may concern Be it known that I, DANIEL l/VILLIAM SNow, a citizen of the United States,;residing at Fillmore, in the county of Ventura and State of California, have invented new and useful Improvements in Wire-Rope Sockets, of which the following is a specification.

My invention relates to awlre rope socket,

the principal objects of my invention being to provide a relatively simple and eflicient socket connection between a wire rope or cable and a drill'shank, further to provide a wire rope socket that may be readily assembled or taken apart and which when".

properly connected will provide a firm and substantial connection between the wire rope or cable and the drill shank, and further to generally improve upon and simplify the construction of similar types of existing sockets and connecting devices.

'VVith the foregoing and other-objects in view, my invention consists in certain novel features of construction and arrangement of parts that will be hereinafter more fully accompanying drawings, in which:

Figure 1 is a vertical section taken centrally through a wire rope socket and connecting device of my improved construction. Fig. 2 is a horizontal section taken on the line 2-2 of Fig. 1.

'Fig. 3 is'a'horizontal section taken on the line 3-3 of Fig. 1. v

Figi l is an elevational view of one of I the slipsor wedge plates that is utilized in:

my'improved socket connection. I

Referring by numerals to the accompanying drawings which illustrate a practical embodiment of my invention, 10 designates 1 the upper portion of a drill shank, and projecting upwardly therefrom is an axially disposed externall threaded stud 11 that is adapted to be engagedby the internally lower threaded end of a tubular member 12 that formsthelower portion of the body of my improved socket connection.

The bore of chamber 13- that'isformed through'member 12 gradually decreases in diameter toward its upper end, and the upper portion of said member 12 is provided with a relatively short internally threadedportion 14 that is adapted to receive the externally threaded depending portion 15 of the uppermember 16 of the socket connection The bore or chamber 17 Specification of Letters Patent.

that is formed in this upper member 16 gradually tapers toward its upper end, and the size of said bore or chamber is such that itforms practically a continuation of the tapered bore or chamber 13 in the lower socket member 12.

Members 12 and 16are provided in their outer faces with recesses 18 that areadapted to receive spanner wrenches or the like, and which are utilized in connecting or d1SCOI1-I necting the parts of the socket. The lower portion of the trim rope or cable 19 to which my improved socket is applied passes-s through an opening 20 in the upper end of member 16 and downwardly through the tapered chamber within socket members 12' and 16, and the end portion of said rope or cable is untwisted for a short distance. and the core of saidrope or cable within the untwisted portion and within that por I tion immediately adjacent to the upper end of the untwisted portion is removed so as to receive the body portion of a. spreader plug 20', and which latter is provided at its upper end with an upwardly projecting pin 21 which enters the chamber formed'in the lower end of'the twisted end of the cable by the removal of the goods thereof.

*The lower portion of the body or plug 2O tapers toward its upper end, while the upperportion of said body gradually tapers toward its upper end, and the untwisted wires of the cable are arranged so that they extend downwardly over the inclined surfaces of the upper and lower portions of said alug. j

1 En'circling the lower portions of the'wires or those portionsthat are positioned on the downwardly tapered lower portion of plug 20-, is a ring. 22 that occupies the lower portion of the chamber 13, and encircling the upwardly tapered upper portion of said plug and the portions of the wires that are disposed thereupon is a ring 23. Obviously, the openings through rings 22'and 23 are tapered to correspond with the tapered surfaces of the plug 20, and when the parts are properly assembled, the rings 22 and 23 very effectively secure the untwisted end portions of the wire rope'orcable upon the plug.

Disposed within the tapered chamber in the socket members 12 and 16 above the ring 22 is a'p'air'of rope or cable engaging members or slips '24, each of which is substantially semicircular in cross section, and provided on its inner fiat face with a vertically wdisposed groove 25, the surface of which is.

.posed wire rope or cable when the partsare properly assembled. The curved outer faces of the slip members 24 gradually taper toward their upper ends so that saidmembers, when properly associated, form an elongated tapered member that will fit snugly within the tapered chamber in members 12 and 16.

Arranged within the upper end of chamber 17 in the upper member 16 is a packing ring 27 that is engaged by the upper ends of the slip members 24: and which is effective in preventing sand, water, or the like, from passing through the aperture 20 in the upper end of member 16 and enteringthe tapered'chamber within the socket members 12-and 16;

When the parts of my improved wire rope socket are propely assembled they occupy the positions illustrated in Fig; 1, and when so arranged the end of the wire rope or cable is Very effectively clamped within the socket, and the lower portion thereof may be read ily applied to or removed fromthe threaded extension 11 ofthe drill shank 10.

T0 disconnect the wire rope or cable from the socket, upper member 16 is unscrewed from lower member 12 and lifted'a suitable distance upon the rope or cable 19, and as a result of blows of a hammer or like tool upon, the upper ends of slip members 24, the latter may be driven downwardly through member 12 until the rings 22 and 23 and plug 20 are positioned below the lower end of member 12, and when so positioned said rings and plug may be readily separated and disengaged from the spread wires at the end of the rope or cable. a

A wire rope socket of myimproved construction is comparatively simple, is capable of being readily assembled or taken apart, and is very effective in performing its intended functions.

- It will be readily understood that minor changes in size, form and construction ofthe various parts of my improved wire rope socket-may be made and substituted for those herein shown and described without departing from the spirit of my invention, the scope of which: is set forth in the appended claims. i
