110mm x. moans AND JOHN 1mm. or TULSA, cxmnou cnLE-snAcxLn Specification or Letters Patent. Patented Dc. 27, 1921,.

Application filed September a, 1920. Serial No. 400,060.

To allwhomit may concern Be it known that we, HOMER M. RHORER and JOHN T. DAvIs citizens of the. Uni ed States, residing at 'lulsa, in the county of Tulsa and State of Oklahoma, have invented certain new and useful Improvements in Cable-Shackles, of which the following is a specification. ThlS invention relates to shackles for attachmg cables, such, for mstance, as connecting elevator cables with their support;

and although useful'especially for'application to the ends of cables, it can be applied as well for points. v

The object is to provide in a shackle of gripping cables at intermediate this kind, a novel cable-:g Lrcipping element.

whereby the shackle may be onnected to the cable quickly and easily, as well as securely;

to provide such an element whereby the shackle may be connected to, or disconnect ed from, the cable more quickly and easily than with previous devices of similar general nature; and to provide a light, simple, strong and durable cable shackle which can be applied to and disconnected 'fromthe cable quickly, easily, safely and securely.

[The invention comprises a socket formed with astem and with a hole hav ng tapered sides and a tapered split wedge fitting in said hole and bearing against said tapered sides, said wedge comprising two members having opposite gripping faces for 'rip ing .the cable and said faces being specially formed to conform to the surface of the cable; and it further consists of the certain parts, improvements and combinations herein set forth and claimed.

In the drawings accompanying and forming part of this specification and in the description of the drawings, we.have shown our invention in its preferred form and what we deem to be the best-mode of applying the principles thereof; and ,it is to be understood that, within the scope of the appended claims, we-contemplate changes in form, proportions and materials, the transposi: tion of parts and the substitution of equivalent members, without departing from the spirit of our invention.

Figure 1 is a side elevation of a cable shackle made in accordance with the principles ofqour invention. Fig. 2 is a center sectional elevation-on a plane indicated approximately by the line '2-2 in Fig. 1,

showing it applied to theend of a cable,"

vation of the split wedge.

Fig. 3 is a top" view of, the split wedge as .1t clamps the cable; and Fig. 4 is the same view without the cable. "Fig. 5 is a side ele- Fig. 6 is a sectional plan of the socket, approximately-on a plane indicated by the line 6-6 in Fig. 1, the split wedge beingremoved. Similar reference characters indicate like or corresponding parts throughout-the severalvlews.

p The main or socket membercomprises the socket 5 and stem 1, the two being connected by the two

legs

7, 7, leaving the space above the socket hole 8 open, as clearly shown in the drawings. Oppositesides of the-socket are tapered, as shown at 8 for the reception of the .split wedge as hereinafter explained, and the intermediate sides are rounded, as shown at 9, to admit the maximum size of cable.

Thesplit wedge comprises the two clamp- .mg members2, 2, both having tapered outer sides to fit against the corresponding tapered sides of the socket hole and also having opposite clamping faces 10 to clamp opposite sides of a cable 3 inserted therebetween. The clamping faces are rounded corresponding with a segment of the cable of the cable is preferably wrapped with fine wire as shown at 4.

To use the device, the cable end is inserted through the hole in the socket, the wedge members are clamped to oppositesides. of the cable and driven down into the hole with the tapered outer faces of the wedge members fitting against the tapered sides of the .hole, the wedge members being driven down To detach the shackle from the cable, the wedge members are lifted up until the cable is loose when it may be withdrawn, and the loosening of the wedges may be effected by lifting or prying upwardly agains'tthe shoulders'll, 11 formed on their outer sides or under their heads. The

- shackle may be applied to any intermediate part of the cable by permitting the cable to 'extend through the opening between the stem and the socket. I

The long 'arallel gripping surfaces of the wedge mem rs with the long tapered engagements between the wedge members and the sides of the socket, insure a firm hold on the cable which tightens with increased strain. H Each socket will grip any cable of a' diameter ranging down from the maximum size admissible through the hole; and it is contemplated that various wedges may be provided for any given socket to conform to the diameter of the cable, and, for the most perfect fitting, to the surface of the cable.

By reason of the'rounding, or i'ecessing,

of the body of the socket, at 9, on .the oppo- N site sides intermediate the tapered sides, a cable having a diameter greater than the 15 width of the wedges may be inserted through the socket and held therein by the wedges.

- Having thus described our invention, what we claim is: 1

The combination of a socket member formed with a stem and a hole having tapered opposite sides, and a split wedge comprising two members having parallel oppo- HOMER M. RHORER. JOHN T. DAVIS.
