Oct. 16, 1956 D, KELLEMS CABLE GRIPS Filed May 22, 1951 I I INVENTOR Y ,WLJLLE/w United CABLE GRIPS Application May 22, 1951, Serial No. 227,639

7 Claims. (Cl. 24-123) This invention relates to braided, open mesh, wire cable grips, and more particularly to the end loops, eyes or endings of such devices, whereby a grip with an article gripped therein, may be attached to a pulling line or a supporting means.

Many attempts have been made in the past to produce satisfactory pulling eyes for open mesh cable grips, but while some of such prior eyes were advantageous in some respects, they possessed disadvantages in other respects, which detracted from their success in practical use. To operate properly in use, the pulling eye of a cable grip must be simple in construction, be of small size and at the same time be as strong as the open mesh tube or body of the grip. These factors are of especial importance where the grip is designed to pull cables through conduits.

The principal object of the present invention is to provide an improved cable grip eye, which will be exceedingly simple in construction, of small size and yet will enable the full strength of the grip to be utilized.

The above object is achieved in accordance with the invention, by selectively ending certain of the strands of which the body of the grip is formed, in a mechanically swaged collar, and by extending selected other strands of such body through such collar and weaving them either alone or with additional wires, into a rope or ropes suitable for forming the eye or eyes desired.

The invention also contemplates providing an improved cable grip in which the woven extended wires of the eye are evenly stranded into a smooth, perfect rope-shaped form.

A further object of the invention is to provide an improved cable grip with a simply constructed, completely successful, swivel eye.

Other objects of the invention as well as the advantages thereof will become apparent after a perusal of the following description when read in connection with the accompanying drawings, in which Fig. 1 is an elevational view of a cable grip constructed in accordance with the invention; Fig. 2 is a similar view of the upper portion of such grip, on an enlarged scale and partly in ,section to show the assembly more clearly; Fig. 3 is an exploded view, partly in section, showing the draft end of a grip made in accordance with the invention, but provided with a pulling eye, which will rotate or swivel relative to the body of the mesh; Fig. 4 is an elevational view of the draft end of a lufng or slack-type pulling grip with the same eye construction as shown in Figs. 1 and 2, and Fig. 5 is an elevational View of the draft end of another embodiment of the invention.

In the drawings, the reference number indicates generally, the body of the grip in all of the several modifications of my invention. The body 10 of the grip is composed of a plurality of wire strands interlocked or interwoven to form an open mesh structure adapted to be placed in surrounding gripping relationship with an article and having any suitable form. Some examples of the forms in which the grip body 10 may be made are illustrated in the E. E. Kellems Patent No. 2,017,625, issued October 15, 1935. The strands of the grip body 10 in all of the several embodiments are preferably formed with looped ends 11 and braided toward the pulling or draft end of the grip. The strands or wires at the pulling end of the grip are then gathered into a single group which extends through a tubular collar or sleeve, such as the collar 13 shown in Fig. 2 of the drawings. The strands or wires may also be grouped into pairs between the grip body 10 and the aforesaid single group thereof, and each such pair threaded through a tubular protecting member 12 (note Fig. 3). Each of the members 12 are straight for the major portions of their lengths and then are inclined inwardly toward the collar. By this construction, the neck of the grip is maintained as flexible as possible and the shoulders formed by the members 12 afford protection to the end of the gripped cable and to the pairs of strands or Wires against wear and prevents the mesh from slipping forward in the use of the grip.

The collar 13 may be made of any suitable material, but it is preferred that it be made of a metal which readily lends itself to swaging, such as aluminum. In the form of grip shown in Figs. 1, 2 and 4 of the drawings, the upper end of the collar 13 is preferably tapered. The single group of wires enclosed by the collar 13 are composed of wires 1S which have been ended in such collar, and wires 16 which extend through the collar and are continued outward therefrom. The wires 16, beyond the collar 13, are twisted smoothly upon each other into rope form and the outer end 17 of such rope is turned back and inserted into the collar 13, thereby forming a loop 18 at the draft end of the grip. A wedging pin 14 may be inserted in the remaining space in the collar 13, so that a minimum reduction of the collar 13 will be required in the mechanical swaging operation which is next applied to the collar 13. The collar 13 is swaged tightly upon and around the wires and wedging pin or pins 14, preferably by rotary swaging, but may be accomplished by any other suitable method to produce the necessary reduction in diameter or to secure the wire ends 15 and rope end 17 in position within the collar 13.

It will be understood from the foregoing that selected wires forming the body of the grip are ended in the collar 13 and that a selected number of other wires forming the body of the grip are continued through the collar 13 to form the loop 18, as the number o-f wires used to form the mesh 10 of the body of the grip is greater than has been found necessary to form a loop or eye 18 of adequate strength. Furthermore, by ending a selected number of these wires in the collar, the number of wires remaining may be controlled so as to produce a smooth, tightly stranded rope of adequate strength and flexibility for forming the eye or pulling loop 18. It has been found that the number of wires retained for stranding in the eye 18 should for best results be either seven or nineteen wires depending upon the number of wires that has been used in the construction of the mesh 10. Thus, for example, if seven wires are selected, such wires can be twisted so that they provide a rope which is tightly stranded, yet smooth and perfectly round in cross-section, without sacrifice of strength or flexibility. Under certain conditions, such as when the number of wires in the mesh 10 are not suicient for proper stranding, it may be necessary to add one or more additional wires having a length such as to enable them to start in the collar 13, be stranded with the other wires into the rope of which the loop is formed, and ended with the rope end 17 inthe collar 13.

If it should be desired to increase the length of the wires between the body 10 of the grip and the collar 13 in order to attain increased flexibility in the neck portion of the grip, this may be accomplished without sacrifice of the flexibility thus attained and without slipping of the mesh by employing a flexible tubular holding or retaining member 19 such as shown in Fig. 4 of the drawings. This flexible member 19 abuts against the lower end of the collar 13 and cooperates with the latter to hold or retain the wires in proper position at the neck of the grip, but because of its flexible nature and the increased length of the wires in such region, it makes for greater flexibility in the neck of the grip, The exible member 19 may be made of any suitable material. For example, it has been found that a piece of braided neoprene hose of standard design functions satisfactorily.

If the wires are not to be llengthened between the collar 13 and the body 10 of the grip, I have found that the employment of resilient means in such region enables the accomplishment of other advantageous results. In Figs. l and 2 of the drawings, such means is shown as being composed of an inner resilient member 20 and an outer resilient member 21. The member 20 may be made of rubber or other suitable resilient material and is slightly tapered upwardly. The outer member 21 is in the nature of a sleeve made of molded neoprene and of such dimensions that it tightly compresses the wires about the inner member 20 and between the latter and the collar 13, such compression being sufficient to hold the inner member securely in position without the necessity of additional holding means. By reason of this construction, the wires of the grip in the region of such members are held securely in position so that the mesh body will retain its full diameter without collapsing or necking-down at the pulling end, thereby facilitating more rapid assembly of the grip or cable ends. In addition to coacting with the inner member 20 to attain this result, the outer member 21 protects the corners from abrasion at the shoulder and provides a smooth, exible leading portion or shoulder to the grip to facilitate the threading of the grip through electrical conduits.

In the embodiment shown in Fig. 3 of the drawings, the wires of the mesh body 10 are all ended in a collar 24 which forms part of a swivel unit. As in the construction shown in Fig. 2, an internal wedging member 25 may be inserted in the collar 24 to take up the space remaining after insertion of the wires to minimize the required reduction of the collar in swaging such parts together. It has been found that the wedge 25 will give best results if it is slightly tapered and is inserted from the outer end, 4

as shown. The slight taper in the pin or wedge 25 not only makes it easy to insert and increases the wedging action, but after the collar 24 is reduced by swaging, such taper also causes a gradually increased binding action on the wires so that the full strength of the mesh body 10 is maintained with a minimum size of collar 24. This minimum size is essential to the construction illustrated in order to produce a pulling eye which is free to rotate on the collar 24 and at the same time is compact enough to pass Vfreely through the limited space of an electrical conduit. Mounted `on the neck of the grip between the collar 24 and the grip body 10 are a threaded member or internal nut 26 and a pair of anti-friction discs or washers 27, which are threaded on the neck of the grip before the collar 24 is mounted on the wire ends. The collar 24 and thrust washers 27 have a cross-sectional area such that they may be passed through the internally threaded end 28 of a pulling eye 29 provided with an internal chamber 30 for the reception of such parts. The nut 26 is then screwed into threaded engagement with the end 28 of the pulling eye and locked in place therein by peaning or in any other suitable manner. It will thus be understood that the pulling eye unit, composed of the members 26 and 29 will freely rotate upon and about the collar 24, thereby producing a swivel pulling eye of compact design and substantial strength.

It will be noted that the cable grip shown in Fig. 4 of the drawings has a draft end which is offset from the grip body 10 in order to enable the gripped cable 30 to be extended therethrough. This type of grip is of special advantage for removing cables from a conduit or for pulling up slack near the end of the cable. It has been found that in the use of such a grip, certain of the wires of the body 10 are not placed under tension by the pulling force exerted on the grip. Such wires may be ended in the eye collar 13 in the manner previously explained, but in order to reduce the number of wires gathered together in such collar, certain of such slack wires may be cut short and ended in the Lipper end of the grip body 10. Thus, as shown in Fig. 4, the slack wires 31, 31 have been cut short and their ends secured together and to a lead wire 33 which extends into the collar 13, by means of a tubular clip 32 which after such wires have been enclosed thereby, is flattened to permanently secure them together. By this construction the mesh at this point yof the grip, will retain its shape and the lead wire 33 is prevented by the clip 32 from cutting into the jacket of the cable.

In the embodiment shown in Fig. 5 of the drawings, certain selected wires are ended inside the collar 34, and certain selected wires are extended through such collar 34 as in the constructions of Figs. 2 and 4. The grip shown in Fig. 5 differs in the respect that the extended wires are formed into two branches, 35, 35 and the wires in each branch are woven into rope form. The ends of the ropes formed by the wires in branches 35, 35 are inserted into the opposite ends of a U-shaped metal tube 36, preferably so that the ends of such branches are in overlapping relation within the tube 36. The metal tube 36 is then tightly compressed upon the overlapping ends of the branches 35, 35 thereby forming with such branches, an open-shaped loop or eye by which the cable grip may be pulled. It will be understood that instead of dividing the extended wires into two branches to form one loop as shown in Fig. 5, the extended wires may be divided into more groups to form two or more of such loops depending upon the purposes for which the grip is made. It will also be understood, that by so ending a selected number of the wires in the collar 34 and dividing the selected extended Wires into two or more branches, each branch can be made up of the proper number of strands or wires which will enable the formation of a perfect rope. Thus, this construction not only enables the production of an eye having uniform perfect stranding, but as a consequence thereof, provides an eye of improved appearance and increased strength. In this connection also, it may be advisable in some cases, to extend all of the wires of the grip body 10 through the collar 34 and utilize all of such wires for stranding, and even add additional wires which begin inside of the collar 34 and extend outwardly therefrom in order to provide in each branch a number of wires which can be formed into a perfect rope, as has previously been explained.

While I have hereinabove described and illustrated in the drawings, preferred embodiments of my invention, it will be apparent to those skilled in the art that changes and modifications may be made therein without departing from the spirit of the invention or the scope of the appended claims.
