9 Claims. (c. 24-23) This invention -relates to improvements in cable bitches.

It is common practice to form a slip loop on the end of a, cable for the purpose of making suitable connection with an object which is to be lifted or pulled by a. crane or other device. Heretofore, it has been common practice to secure a hook on the end'of the-cable and to engage the hook withanother part of the cable after the latter has been looped around the object. A hook is objectionable for several reasons: It has a tendency to cut into the cable and cause wear on a. certain portion thereof; it is likely to become disengaged and result 'in dropping of an object; it has a. tendency to catch objects after it is free from the object lifted and is being dragged on the ground by the crane or other power device; and a hook, to be properly Secured, requires doubling of the end of the cable thru the eye of the hook, and this doubled portion prevents 'the formation of a loop of small diameter, which is frequently desirable in the lifting of pipes or the like.

It is therefore one of the objects of the present invention to provide an improved cable hitch designed for use in place of the ordinary hook, which hitch is well adapted for use in connection with crane cables, tow lines, mooring lines, and the like.

A further object of the invention is to provide an improved cable hitch which is so constructed as to permit the formation of a relatively small surfaces to prevent cuttng into the cable and consequent wear thereon.

A further object of the invention is to provide an improved cable hitch which is simple in construction, strong and durable, inexpensive to manufacture, and well adapted for the purpose described.

With the above and other objects in view, the invention consists of the improved cable hitch and all its parts and combinations as set forth in the claims and all equivalents thereof;

Inthe accompanying drawing, illustratin'g one complete embodiinent of the preferred form of the invention, in which the same reference numerals designate the same parts in all o'f the views: y

Fig. 1 is a perspective View, showing' the improved device in conjunction with a cable end and forming a loop therein;

' Fig. 2 is a sectional view taken on line 2-2 of Fig. 1;

Fig. 3 is a view of one side of the device; and Fig. 4 is a detail, perspective view of the wedging element. I

Referring more particularly to the drawing, the

device consists, in general, of a triangular casting 5 of suitable metal having one side edge formed with a pair of spaced hooks 6 and 'i which extend in reverse directions. The said hooks are relatively long, as illustrated, to provide long hearing surfaces for engagement with the cable.

The other side of the casting is formed with a threaded bore (see Fig. 2) joining an unthreaded conical recess A smaller recess io extends inwardly from the end of the conical recess. A sight opening i i extends from the smaller recess i& to the face of the casting.

A clamping member or nut !2 has external threading as at !3 and has a bore M which communicates with an enlarged conical recess portion 85 at the inner end of the member.

A wedging element Mi (see Fig. 4) which is substantially double cone in shape is positionable in the recesses &E and 9. said element is formed with spaced apart, longitudinal grooves t'i and may be formed at its inner end with other grooves it?. i

To secure the cable end within the bore of the device, said end is first inserted in the bore l 40 of the` nut member !2 and is then frayed out in the concal recess !5. Next, the wedging element i& is inserted in the recess in the manner shown in Fig. 2, with the separate strands of the cable positioned in the grooves l'i of the wedging element and with the extreme frayed ends of the cable projecting beyond the end of the wedging element. The nut member [2 is then threaded into the bore &3 in the manner shown in Fig. 2, and this causes the strands of the cable to be clamped between the wedging member and the walls of the conical recess !5. At the same time,- due to the turning of the-nut l2, the strands at the extreme end of the cable are twisted together in the recess o as indicated by the nu- 66 meral IS to theteby firmly wcdge and clamp the cable end in position. The sight opening ll is provided so that the user can see whether or not the twisted end !9 of the cable is within the small recess IO. If it -is so positioned, he knows that the cable is securely clamped.

This serves to secure the cable end to the hitching device without the necessity for doubling the end of the cable, as is the case when a hook is Secured to a cable end. As a result, the cable may be looped around as shown in Fig. 1, I

with a portion engaged with the hooks 6 and 1, and the cable may be pulled to form a loop of relatively small diameter.

The novel shape of the unit lends itself peri'ectly to the formation of a loop, and the novel form of reversely bent hooks 6 and 'I provides for secure engagement with the inner portion of the cable while permitting slippage for tightening of theloop. In addition, as before mentioned, the long bearing surfaces of the hooks prevent cutting into the cable.

The books further provide for 'quick detach-` ment, as it is merely necessary to pull the cable portion 20 free of the hook 1, the cable portion 2I free ofthe hook 6, and then slip the cable out of the space 22 between the hooks.

It may easily be seen that the device is so shaped, with the rounded, fiat hook portions 'that it will not, when permitted to drag on the ground, catch into other objects and cause trouble. It will further be seen that the combination with the unusually strong and effective clamping means illustrated in Fig. 2 provides for a connection which will withstand unusual strains. l

Altho only one form of the invention has been shown and described, it is obvious that various modifications may be made therein without departing from the spirit of the invention; and all of such modifications are contemplated as may come within the scope. of the claims.

What I claim is:

1. `A cable hitch device comprising a body portion having means for attaching the end of a cable thereto, and a pair of reversely bent hook portions in connection with said body engageable with successive portions of a cable for removably holding the cable in looped form.

2. A cable hitch device comprising a body portion having means for attaching the end of a cable thereto, and a pair of reversely bent hook portions in connection with said body for' removably holding the cable in looped form, said hook portions being of substantial width to provide long bearing surfaces for cooperation with the cable. the longitudinal axes of the hearing surfaces being in substantial longitudinal alinement to engage successive portions of the cable.

3. A cable hitch device comprising a body portion having means on one side for attaching the end of a cable thereto, and a pair of reversely bent hook portions in connection with the opposite side of said body positioned in substantial longitudinal alinement to engage successive portions of a cable and hold the cable in looped form.

4. A cable hitch device comprising a body portion having means for attaching the end oi a cable thereto, and a pair of reversely bent hook portions in connection with said body positioned in substantial longitudinalalinement to engage successive portions of a cable and removably and slidably hold the cable in looped form.

5. A cable hitch device comprising a substan-' tially triangular body portion having means along one side for'attaching the end of a cable thereto, and a pair of reversely bent hook portions in connection with the opposite side of said triangular body and removably hold the cable in looped form.

6. A cable hitch device comprising a body portion having a bore therein, means cooperable with said bore for clamping a cable end within the bore, and reversely extending hooks carried by the body portion and removably hold the cable in looped form.

7. A cable hitch device comprising a substantially triangular body portion having a bore along one side thereof, means cooperable with said bore for clamping'a cable end within the bore with the cable extending from the side of the body corresponding to the base oi' the triang1e, and means carried by the third side of the triangular body portion for removably holding the cable inlooped form.
