--4 Claims. (Cl. 24-134) .This invention relates to a grip for a cable or the like, the general object of the invention being 'to providea device which can be easily and quickly attached to and detached from a cable or the like and which canbe used for, a great number of: different purposes, and the greater the pull exerted upon the'device, the firmer, the. jaws of the device will grip the cable ,or other member.

This invention also consists in certain other featuresof construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustratedin the accompanying drawings and specifically pointed out in: the appended claims. I I

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts, throughout the several views, and in which:-

Figure 1 is an elevation of the device.

Figure 2 is an edge view thereof.

Figure 3 is a section on line 3-3 of Figure 2.

Figure 4 is a section on line 4-4 of Figure 1.

Figure 5 is a section on line 5-5 of Figure 3.

Figure 6 is a fragmentary view showing modified forms of jaws.

In these drawings, the numeral 1 indicates the body of the device which is reinforced by ribs 1', and said body is formed with a chamber 2 for the jaws and their operating means and with a slot 3 for the entrance of the member to be gripped, this slot passing through the front face of the body. A pair of studs 4 passes through the body from rear to front, through the chamber and forms bearings for the eccentrics 5, each of which is encircled by an eccentric strap 6 having a projection 7 thereon to which a jaw 8 is pivoted, as shown at 9. An arm 10 is connected to each eccentric, said arms extending through openings in the sides of the body and have holes 11 at their outer ends for receiving the ends of the chains 12, the other ends of the chains being connected to a ring 13 and a cable or pulling member 14 has one end connected to the ring. Instead of using the chains 12, links may be used.

Thus it will be seen that by passing a cable or other member through the slot 3, with a portion of the member passingbetween the jaws,

.and then exerting a pull upon the member 14, the chains 12 will swing the arms 10 upwardly so that the jaws will move toward each other and thus the jaws will grip the cable or other member so that the said member is connected to the body. Then a further pull on the member 14 will exert a pull upon the cable or member gripped by the jaws 8.

A member 15 is connected to a triangular member 16 which in turn isconnected to the body 1 by the clevises 1'1 and byslackening the member 14 and exertinga pull upon the member, 15, saidbody 1 will bemoved while the member grippedby the jaws8 is held stationary and thus the arms 10 will-.move the jaws to releasing position. I

Projections 18 are are engaged by pins 19 on the arms 10 for limiting-opening movement of the arms. When the device is used for heavy work, a strain link or 4 and held thereon by the cotter pins 21 passing through the front ends of the studs, this plate or link strengthening the parts. When it is not desired to use this link, it can be removed and I the cotter pins placed in the holes 22 formed in the front ends of the studs, as shown in Figure 5,

to hold the studs in place.

In order to prevent the cable or member to be gripped from moving out of the slot 3 before the jaws are moved to clamping position, I provide a substantially U-shaped bar or safety link 24 which has its ends fitting between the projections 23 formed on the front face of the body and this link or bar is held in place by the pins 25, which in turn are held in position by the cotter pins 26.

When desired, this safety link 24 can be removed and only the pins 25 used to hold the cable in position.

The gripping edges of the jaws 8 may be-formed to suit the work to be done by the device. For W instance, Figure 3 shows the jaws provided with grooved gripping edges, as at 8, while Figure 6 shows the jaws provided with projections 8" for gripping a link of a chain, for instance.

As before stated, this device can be used in various situations and in different ways according to the wishes of the user, and as will be seen, the greater the pull upon the device, the firmer the jaws will grip the cable or other member.

The front wall of the chamber 2 is formed with '0 the pairs of inwardly converging shoulders 27 which form guides for the portions 7 so that the gripping jaws are moved in a straight line, with their gripping edges remaining parallel during their opening and closing movements and, as shown in the drawings, the pivots 9 are formed with the jaws. It will be seen that the link or plate 20 acts to hold the cable in position while the member 24 is being put in place.

The extended upper and lower ends 28 of the formed on the body land I plate 20 is placed over the front ends of the studs lower member of the body can be used as anvils for making repairs and the like and these parts are provided with the holes 29 which may be used for different purposes and also used for attaching the body to a supporting member when it is desired to hold the body stationary.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:

1. A device of the class described comprising a body having a chamber therein and a longitudinally extending slot passing through the front face of the body, a pair of jaws in the chamber for gripping a member passed through the slot, eccentrics pivotally arranged in the chamber, straps for engaging the eccentrics and having projections to which the jaws are pivoted, outwardly extending arms connected to the eccentrics, a pull member, means for connecting the arms to the pull member, a second pull member, means for connecting the same to the body.

2. A device of the class described comprising a body having a chamber therein and a longitudinally extending slot passing through the front face of the body, a pair of jaws in the chamber for gripping a member passed through the slot, ec-

centrics pivotally arranged in the chamber, straps for engaging the eccentrics and having projections to which the jaws are pivoted, outwardly extending arms connected to the eccentrics, a pull member, means for connecting the arms to the pull member, a second pull member, means for connecting the same to the body, a safety link detachably connected to the front of the body for holding the member to be gripped by the jaws therein, and a strain link detachably connected to the eccentric pivots.

3. A device of the class described comprising a body having a chamber therein and a longitudinally extending slot passing through the front face of the body, a pair of elongated jaws in the chamber for gripping a member passed through the slot, eccentrics pivotally arranged in the chamber, straps for engaging the eccentrics and having projections to which the jaws are pivoted, guiding means for causing the jaws to remain parallel during their movements, outwardly extending arms connected to the eccentrics, a pull member, means for connecting the arms to the pull member, a second pull member, and means for connecting the same to the body.

4. A device of the class described comprising a body having a chamber therein and a longitudinally extending slot passing through the front face of the body, a pair of elongated jaws in the chamber for gripping a member passed through the slot, eccentrics pivotally arranged in the chamber, straps for engaging the eccentrics and having projections to which the jaws are pivoted, guiding means for causing the jaws to remain parallel during their movements, outwardly extending arms connected to the eccentrics, a pull member, means for connecting the arms to the pull member, a second pull member, means for connecting the same to the body, and upper and lower extensions formed on the body forming anvils and having holes therein.
