OSCAR F. SHEPARD, OF CINCINNATI. OHIO, ASSIGNOR TO THE WARNER ELEVATOR MFG. COMPANY, OF CINCINNATI, OHIO, A CORPORATION OF OHIO.

CABLE-CLAMP.

Specification of Letters Patent.

Patented Aug. 7, 1917.

To all whom it may concern:

Be it known that I, OSCAR F. SHEPARD, a citizen of the United States, and residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Cable-Clamps, of which the following specification. is a full disclosure.

My invention relates to a cable clamp, adapted for heavy duty, attachment to an elevator, ship-anchor, or the like.

An object of the invention is to provide a holder or cable end clamp enabling the end of a woven wire cable to be effectually headed and clamped, and reliably held against longitudinal or rotative movement.

Another object of the invention is to prevent strains tending to crystallize the metal in proximity to the headed end, and to grip the cable under forces applied at different points and effective in different relations to the cable.

The features of the invention will be more fully set forth in the description of the accompanying drawings, forming a part of this specification, and wherein:

Figure 1 is a side elevation of the clamp.

Fig. 2 is a vertical section.

Fig. 3 is a front elevation.

Fig. l is an elevation of one of the detachable clamp members showing the inner surface scored or of a configuration to fit the cable strands.

Fig. 5 is a front elevation of a modified form of clamp.

Fig. 6 is a side elevation thereof.

Fig. 7 is an elevation of the detachable clamp member of the clamp shown in Figs. 5 and 6 showing the inner scored surface.

The cable-holder comprises a tapered socket portion 1 and a grip portion 2, the end of the cable strands being expanded and bent back to form the head 3, the anchoring agency being generally the Babbitt metal 4. The grip portion has relatively movable members, specifically, the plates 5-6 having the cable-way or jaw portions 7 provided with the spiral contour depressions 8 to fit the weave of the cable strands. The grip or clamp members are clamped by four bolts assing through the jaws at opposite sides of the cable 10 and embrace the cable just below its expanded anchor-head. The flared end of the socket member 1 has the eyes 11 incline-plane-car,

such as the cable" for attachment to another member, say the elevator.

The socket and its taper portion and grip portion may be formedof the detachable plates 5-6 and the socket 1, as shown in Figs. 1 or it may be the substantially integral structure'shown in Figs. 56, wherein the taper socket portion 15 is in the shape of a sleeve having a jaw extension 16 form- .ing one of the grip members to cooperate with the movable or separable grip member or jaw plate 17.

The detachable grip plates 56 as shown in Figs. 1t cooperate with the standard type of cable socket 1, their upwardly extending limbs being contoured to fit the outer surface of said socket and bent inwardly to hook over the upper edge thereof. A tie bolt 18 engages through orifices in the upper bent ends of the plates 5 6 and passes between the socket eyes 11. These plates are further secured to the socket 1 by screws 19 screw threaded into the socket wall.

This type of detachable grip plates has special utility as a repair device and for attachment to standard sockets and cables as a preventative against cable crystallization, while the integral type shown in Figs. 5-7 may be preferable for use in connection with new cable installations.

The cable head is Babbitt anchored in the taper socket or sleeve, and cannot be strained loose, the clamp grip on the normal diameter portion of the cable holds the cable against rotation and prevents the longitudinal strains from exerting a spiral feed action tending to loosen the securance and to crystallize the metal of the cable.

Having described my invention I claim:

1. A cable end holder comprising a taper socket adapted to have a cable end headed therein, the reduced end of said socket having spaced grip members between which the normal diameter portion of the cable passes from the headed end, and means for diametrically clamping said grip members upon the cable.

2. A cable end holder comprising a taper socket adapted to have a cable end headed therein, the reduced end of said socket hav ing spaced grip members between which the normal diameter portion of the cable passes from the headed end, said grip members having a cable-way on their inner faces contoured to fit the strand weave, and means for diametrically clamping said grip members upon the cable.

3. A cable end holder comprising a taper socket adapted to have a cable end headed therein, the flare end of the socket having means for connecting the socket to another member the reduced end of said socket having spaced grip members between which the normal diameter portion of the cable passes from the headed end, and means for diametca y amping said grip members upon the cable. V

4:, A cable end holder comprising a taper socket, means on one end of the socket, for connection to another member, spaced grip m mbers at the other end of the soe ehand a ca le a ing an xpa ded end headed and anc ed i t e taper portion of the soc et,

for diametrically clamping the grip portion upon the cable below the headed portion. In Witness whereof, I hereunto subscribe my name, as attested by the two subscribing witnesses.
