This invention relates to cable grips which are more particularly intended for pulling slack in cables or holding cables u n-` der tension during splicing operations.

In practice, cable grips are used in connection with pulling slack in cables or splicing of aerial cables under tension and in holding the cables while slacking off the strand to remove bows. Split cable grips consisting of interlaced strands havebeen extensively employed for this purpose, and

rawhide thongs or leather strips have been ordinarily used in lacing theV edges of these grips together. connecting the split grips has been found unsatisfactory because considerable time is required to lace the edges of the grips together, especially in cold weather when the workman is wearing gloves., It has also been found that this method is unsatisfactory because the rawhide thongs do not develop sufficient strength to hold the edges of the split grip together.

Accordingly, it is an object of this invention to provide a rugged cable grip which can be readily applied to a cable at any point in its length and removed therefrom in an expeditious and simple manner. y

The novel features which are considered characteristic of this invention are set forth with particularity in the appended claims.

The invention, both as to its organization and method of operation, together with other objects'and advantages thereof, will be further explained in the following detailed description having reference to the accompanying drawing consisting of the following figures: Y

Figure l is a view of the improved cable grip showing it in position about a cable and the first step of fastening it thereto;

Fig. 2 is a view similar to Fig. l showing a second step required in completing the fastening operation FigsB and 3a are top and side views, respectively, of the improved hook for fastening the longitudinal sides of the grip together; y

Fig. 4: is a view of the grip in extended position;

This method, however, of

Fig. 5. is an elevation of a rectangular fastener which may be used to manipulate the connecting hooks iny the operation of fasteningthe ends Vof the grip together.

In the drawing, the reference Gf represents va short section of cableAk of common form. lThe improved grip 7 comprises a bodyS,

`which assumes a cylindrical form when ap plied to a cable, is composed of a plurality of .interlaced strands 8. The body portion The strands 8 are inclined with respect to the axis of the body so that theypass in helices thereabout. At one extremity the vstrands 8 are attached together vin pairs, as 4indicated at the points 9. At the opposite.

extremity the strands are united so as to form tugs l() havingeyesI in the formvo'f eyes ,or` hand-holes 11 adapted VtoY receive vlingersA so that" the pulling force maybe members 14 ofthe character more clearly villustrated in Figs 3 and 3a are appliedto the loops `forming one longitudinal edge of the split cable and crimpedjthereover, after which 'they are soldered in position. The

flat end of a tool l5 is inserted through the loops forming the opposite longitudinal edge of the cable grip to engage the open ends of the hooks and draw them under and over theiloops to fastenjorv button the two edges together.V When the Vloops arek thus fastened by means of the hooks, theyiuxtapositioned longitudinal edges of the grip are n firmly buttoned together.

By the method above outlined, the diameter of the grip is reduced so that it con- L:

forms closely to the diameter of the cable. If a sliding force is exerted upon the grip at the body thereof the grip may be readily slid along the cable, but if a pulling force is exerted at the tugs l0 the tensile force ex `6o ofthegrip 7 constitutes a basket or bag Vhaving the form ofan envelopingsleeve.

i erted in the strands 8 has the effect of reducing the diameter of the body 7 of `the exerts a firm grip, and in this Way the gr'ip grasp upon the cable.

s In the improved construction disclosed there is provided: an arrangement which may be applied to a-eable in an expedition and 1 simplemanner at any point on its length,
