CABLE HANGER OR CLIP.

SPECIFICATION forming part of Letters Patent No. 548,297, dated October 22, 1895.

Application filed May 15, 1895. Serial No. 549,859. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM P. CROOKETT, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain Improvements in Cable Hangers or Clips, of which the following is a specification.

This invention relates to cable clips or hangers by means of which overhead cables are suspended from a supporting-wire which is attached to suitable supports upon housetops, roof-fixtures, or poles. When a cable is to be extended from one support to another, the

supporting-wire is first strung and permanent] y secured Then a rope is fastened to the cable and carried to a suitable distance from the starting place, where are stationed linemen who pull the cable toward them, and as the cable passes along the clips or hangers are secured thereto at suitable and regular distances and also to the suspending-wire. It is necessary that the clips shall be easily and quickly applied and firmly secured to the cable, so that they shall not slip, and it is also necessary that the hooks or bands resting upon the supporting-wire shallslip therealong readily and easily while the cable is being pulled along, and when the cable comes to rest it is required that it shall be supported strongly and safely by its hangers.

In carrying out my invention I provide a cable clip or hanger consisting of a plain band or strap and a device linked thereto, by means of which the cable is suspended from the supporting-wire and the said band or strap is held to or encircles the cable by frictional pressure. All cable-hangers employing an encircling-band of which I have any knowledge are greatly weakened by the cutting therein of notches or holes to provide for the supporting device.

The clip is adjustable and made to fit cables of any diameter; and it consists, essentially and preferably, of a band or strap of thin flexible metal, such as zinc or of other non-oxidizable and non-resilient metal, provided with a fiat ring at one of its ends, and of a bentwire device, whose ends are shaped into spring suspending-hooks, and a central part which is linked through the said fiat ring and acts in connection therewith upon the band as a wedging cam or binder and jams the same into a bight between the sides of the ring and holds it tightly and firmly to the surface of the cable, the inner surface of the free end of the band being wedged to the outer surface of the cable-encircling portion thereof by frictional pressure, all of which I will now proceed to describe, and point out specifically in the claims.

In the drawings which form a part of this specification, Figure 1 is a perspective View of a portion of cable suspended by'my improved clip or hanger. Fig.2 is a perspective view of the embracing metal band. Figs. 3 and 4 are respectively end and side views of the bent-wire device, and Figs. 5 and 6 are cross-section views of a cable to illustrate the application of the clip thereto.

4 is a band, preferably of zinc, one end 8 of which is bent or foldod over one side or wire of the fiat steel ring 5, as shown, but not in any way fastened thereto, and A is a device made of spring-steel wire, its sides 3 terminating in hooks4, whose ends 5 are brought quite near to the sides 3. Between the central part 7 and each side 3 the wire makes two sudden bends to form the part, so that it will act as a cam or wedge.

When a clip is to be secured to a cable after the device A has been linked through the ring 5, the band 4 is wound round the cable with the fold 8 on the outside, and the end a of the band is passed under the central part 7 of the device A, which has been canted over, as seen in Fig. 5, (or,if necessary, turned upside down,) in order that this may be done and drawn so as to embrace the cable very tightly. Then the device A is turned upward in the position shown in Figs. 1 and 6, and the central or cam part 7 forces that portion of the band which extends over or between the two sides of the ring 5 inward between the said sides, forming a bight. At the same time the fold 8 and the portion of the band under it are also forced inward. When in this position the strip is firmly held by the cam 7, its pressure being maintained by the weight of the cable, so that it cannot slip or work loose. The curved portion of the band 4 between the two sides of the ring 5 forms a sort of lock, although the main resistance to the with drawal of the band is due to the great friction produced by the binding effect of the cam or wedge 7. After the band has been secured to the cable the hooks are sprung over the supporting-wire, the hooks 4 yielding at their lower ends 5', which then resume their normal distance from the sides 3, to prevent the hanger from being detached from the wire.

The device A may be made with one or more books, as can be readily understood, and I do not confine myself to the precise details shown, but I may widely depart therefrom without departing from the spirit of my invention-as, for instance, instead of folding the strap 4 over a flat ringI may fold it over a bar whose ends are bent to form eyes at each end, as shown in dotted lines in Fig. 2.

What I claim, and desire to secure by Letters Patent, is-

1. A cable clip consisting of a band or strap and a device attached thereto provided with means for suspension, and with means whereby when the band encircles the cable the inner surface of the free end of the band is held to the outer surface of the encircling portion of the band by frictional pressure.

2. A cable hanger consisting of a band or strap and a device attached thereto provided with means for suspension and with means for wedging the inner surface of the free end of the band to the outer surface of the cable encircling portion of the band, as set forth.

3. A cable clip or hanger consisting of a band or strap and a wire device linked thereto, provided with one or more hooks for the purpose described, and a wedging cam whereby when the band encircles a cable it is locked thereto, as set forth.

4. A cable clip or hanger consisting of a band or strap one end of which is folded over a ring; and a wire device linked through the said ring, provided with one or more hooks at one extremity, and a wedging cam at the other extremity, by means of which when the band encircles a cable it is held or locked thereto, as set forth.

5. A cableclip or hanger consisting of a band or strap, one end of which is provided with a ring; and a device linked thereto having one or more hooks for the purpose described and a wedging cam, whereby when the band encircles a cable the said band is forced between the sides of the said ring and held there by the said cam, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 15th day of May, 1895.

WILLIAM P. CROCKETT.
