Application filed March 1, 191?, SerialNo. 151,758. Renewed June 4, 1918. serial m; was.

An object of'my invention is to provide a cable grip including a cable engaging block and cap interengageably held by an arrangement of mortise and tenon grooves, the cap supporting a pivoted cable clamp by means of which the block and cap are clamped into tight engagement to clamp the cable.

Another object ofmy invention is to pro vide a cable grip which mayinstantly be removed from engagement w th the'cable and moved to another position thereon so that thel: cable may be grasped at any point at wi l.

. Other objects and advantages will appear from the following specification, reference the accompanying drawing, in which: H

Figure l is a. side elevation showing the cable clamp in position on a cable, the

pivoted clamp member being shown in an open position in dotted lines.

Fig. 2 is a detail central longitudinal section of a portion on the cable grip.

Fig. 3'is a plan view of the in Fig. 1, and

Fig. 4 is a cross-section on the line 4-4 of Fig. 1. p

In carrying out my invention I provide a shoe or block 1 which is substantially of the configuration shown in Fig. 1. The

block 1 is provided with a longitudinal semicircular groove 2 in which the cable 3 is adapted to rest. The block 1 isprovided at each side of the groove 2 with a plurality of lugs or tenons l. The tenons 4: are disposed at an angle which is directed rearwardly for a purposepresently to appear. The forward end of the block 1 is partially rounded as at 5 and forms a clamp engaging surface. A cap 6 cooperates with the block 1 and is also provided with a semicircular longitudinal groove 7 on its under face. Mortises 8 are formed at the sides of parts shown the cap .61and are adapted to'receive tenons 1 of the block 1. In providing the tenons a on the block 1, it will readily be seen that spaces or mortises 9 are consequently.

formed at the'sides ofthe block 1 between the-tenons l." The mortises 9 artoccupied by coacting tenons 10 on the cap 6 when the block and cap are assembled and adjacent. to the pivot 12, is bifurcated as clearly shown in Fig. 3 so as to provide a pair of clamping feet 14L which are correspondingly rounded that they may easily engage the similarly rounded surface 5 on the forward end of the block 1. V

The forward end of the cable clamp 13 is provided withan eye 15 which forms the hitch which may be engaged by a suit able hookwhen it is desired to pull the cable 3. It should be understood with reference to the particular formation of the mortises and tenons of the block 1 and cap 6 respec-,

tively, that these mortises andtenons may be formed in any desirable manner, the feature to be preserved being a rearward in clination of the vertical surfacesthereof.

In other words the particular number or mortlses and tenons on elther side 1S 1mmaterial, and the number thereof may be either even or odd.

Having thus described the construction of the device the operation and manner of its application is as follows:

It frequently occurs in contracting work that a cable structure 3 is to be pulled. An

effective cable grip is at such a time a desirable and necessary implement to have at hand. With the use of my device the lower shoe or block 1 is simply laid to meet the cable 3. The cable clamp 13 is swung upwardly into position shown in dotted lines in Fig. 1, and the cap 6 is superposed on the block 1, the respective rearwardly inclined mortises and tenons being fitted together.

The cable clamp 13 is now swung downwardly on its pivot 12 until the clamp members lt engage the rounded forward surface 5 of the block 1. This point of engagement will now act as a fulcrum and a pull on the forward end of the cable clamp 13 through the medium of a connection inthe eye 15,

will serve to pull the cap 6 forwardly and into tight engagement with the respective surfaces ofthe upstanding tenons'of the block 1. Bearing this forward movement of the cap 6 through the medium of a pull on the cable 13 in mind, it will be readily seen that the engagement of the tenons 10 of the cap 6 the rearwardly" inclined surfaces of the tenons 4; of the block 1, will cause the cap 6 to move downwardly and therefore grip the cable S tightly between the block 1 and the cap 6.

Should it be desired to change the point of application of the cable grip, it is simply necessary to swing the cableclamp 13 up to the dotted line position shown l11:Fig.. 1, when the cap 6 and block 1 may readily be disengaged and moved to another position on the cable 3. Having thus described-the construction of the cable-grip which might be said to be that of a generally preferred form, it should be also understood that various modifications in the construction thereof may be made without departing from the spirit of the invention or the scope of the claims.

I claim 1. A cable gripincluding a block having a semicircular longitudinal cable receiving groove,'said block having a'rounded surface and being provided with rearwardly extending tenons, a cap having a semicircular longitudinal groove and forwardly extending mortises, a bearing lug, on the cap, a cable clamp fulcrumed on the lug, said clamp having a bifurcated portion forming a pair of feet adapted to engage the rounded front surface of the block, said clamp also including a hitching eye. V

v2. A cable grip comprising a'block, a cap positioned upon said block, a' bearing lug projecting from said cap, a cable clamp.piv otally mounted upon said lug, said cable bolt and having a bifurcated portion for.

forming a pairof spaced feet, said feet being adapted to bear upon said block for bringing the same into engagement .with said cap, thus causing a cable interposed between said block and cap to be firmly. gripped, and the bifurcated portionof said lever clamp providing space-for the projection ofthe cable extending therebetween. a

A cable grip comprising a block, a cap positioned upon said block, guiding means;-

formed upon said block and cap for directing the same into engagement with each other, said block and cap having registering grooves, a cable clamp pivotally mounted upon said cap, saidccable clamp having a bifurcated portion thereby formingspaced feet, said bifurcated. portion'registering with the ends of said grooves, and said feet bearing upon said block for urging .the same toward said cap, thus causing a cable inter-- posed between said. block and cap to be firmly gripped.

In testimony whereof I affix my signature in presence of two witnesses. V 7 JAMES H. STEELE. lVitnesses:
