Application filed December 15, 1926. Serial No. 155,044.

This invention relates to devices for hanging or supporting electric cables and wires along the faces of walls, ceilings, fences, or the like.

5 An object of the invention is to provide a simple, inexpensive and efii'ient arrangement of the above character which possesses advantages over those which have been previously used.

Other and further objects of the invention will be apparent from the following description when considered in connection with the accompanying drawing, in which certain embodiments thereof are, illustrated. 1 In the drawing, in which like characters of reference designate like parts throughout, Figure 1 is a side elevation of an improved bridle ring; Fig. 2 is a top plan view there-.

of; Fig. 3 is a section taken on the line AA 2 of Fig. 2 looking in the direction of the arrows; Fig. 4 is an end view of Fig. 1; Fig. 5 is a modification of the arrangement shown in Fig. 1; Fig. 6 is a top plan view of F g. 5; Fig. 7 is an end view of Fig. 5; and Flg. 8 is a perspective view in exploded position of the bridle ring and cable clamp with which it is adapted to be associated.

In practice, it is often necessary, after the mounting of the cable upon a supporting surface to which it is secured by means of a cable clamp, to string additional loose bridle wires parallel to the cable. These wires are usually supported upon bridle rings, and b the present invention the rings 86 maybe use separately for this purpose or 'in combination with cableclamps, to which theymay be attached. v

Referring to the drawing, numeral 5. represents a ring which is composed of a single iece of steel wire. In the present instance, or the urpose of illustration, it is bent in substantially rectangular shape, although other shapes may be used. A pair of arms 6 and 7 extend in parallel relation from a.

Phase 8. The arm 6 has a bent portion 9 which extends at ri ht angles therefrom and terminates in a hoo ed end 10, which overlaps the end of the arm 7 in such manner that a space is provided between the two ends, through which wiresmay be inserted within the confines of the ring. In Figs. 1 to 4, inclusive, the end of the arm 7 is turned outwardly, and in Figs. 5 to 8, inclusive, the end assumes a position parallel to the arm 6. The space or opening provided between the ends of the arms 6 and 7 will be at the front of the ring when it is in position, so that additional wires may be readily inserted through said opening. The

base 8 of the ring 5 is provided with a semi-circular turn or throat 12, and forms a plane at right angles to the plane of the ring. The wire in the throat 12 has a somewhat flattened upper portion in order to provide a better seating for the enlarged head of a hammer-drive anchor, screw, nail,

bolt or toggle by which it is secured to av wall. A counterbored portion 13 may be provided, if desired, around the center of the opening in the ring, so that the wires are I more protected than in former types of rings. A shoulder 14. extends forwardly from one side of the base 13 and extends in a plane beneath said base and connects with the lower end of the arm 6.

The bridle ring is'ada ted to be used independently or in com ination with any form of supporting plate or cable clamp. In its independent use it may be attached to a wall or ceiling in, a vertical or horizontal posit on. The ring is shankless, thereby permlttlng its use on all surfaces by using standard attaching devices. The comparatively wide throat 12 permits the ring 5 to be installed after the attaching device is I placed and almost driven home. The use of the counterbored portion 13 looks the head of the attaching device so that the ring will not fall off even if the attaching device is loosened slightly; This permits rapid installation, especially when installing on hammer-drive anchors, screws, or the like already driven and holdin cable clamps. In this case, the hammerrive anchor or screw is partially withdrawn, the ring inserted and they hammer-drive anchor or screw is tightened again. A common form of supporting plate or clamp with which the mug 5 18 adapted to be used is shown in Fig. 8 or the purpose of illustration. When there is need for additional wires tobe strung, the bridle ring 5 may be attached to the clamp by loosening the screw 16- which secures the clamp to its supporting surface and slipping the bridle ring under the enlarged head of the screw. The screw may he then tightened so that both the clamp and bridle ring are securely fastened to the supporting surface, as will appear below. The clamp is shown as having an opening through which the screw passes to be in sorted in the supporting wall so that it passes through the aligned openings and secures the ring and supporting plate or clamp together against the surface upon which they are to be mounted. When thus mounted with the enlarged head of the screw seated in the counterbored portion of the throat, the ring is locked and prevented from rotating. The rotation of the ring is also prevented by the engagement of the portion of the ring extending from the shou der 17 to the throat portion 12 with the flat side of the hooked portion 18 of the cable clamp. The shoulder portion 14, which extends beneath the plane of the base portion 8 of the ring, engages the edge of the flat portion of the cable clamp 15 and prevents the rotation of the ring in the opposite direction. Thus, when the ring is seated on the supporting plate or cable'clamp, rotation thereof is prevented in one direction by the contact of the portion extending from the shoulder 17 to the throat with the flat face of the hooked portion 18, and in the opposite direction by the contact of the shoulder 14 with the edge of the plate 15.

When the ring 5 is used independently the screw or other seburing means, with the enlarged head seated on the base portion 8, securely locks the ring to the supporting surface. This action is brought about by the pressure exerted by the shoulder 14 on the supporting surface.

It will be obvious that the general principles herein disclosed may be embodied in many other organizations widely different from those illustrated without departin from the spirit of the invention as, defined in the following claim.

What is claimed is:

A bridle ring comprising a single piece of wire bent in substantially rectangular shape and having arms extending substantially parallel with each other for a certain distance, one of said arms being thereafter turned at right angles and forming a hook, the end of which overlaps the end of the other arm with an intervening space therebetween through which wires may be inserted within the confines of said ring, a substantially semi-circular base having a counterbored upper portion and a somewhat flattened lower portion, extensions projecting forwardly from said base, one of said extensions being connected to one of said arms, a shoulder portion connecting the other arm and extension, said shoulder lying in a plane beneath said base and extending in a direction at right angles thereto, and an enlarged head seated on saidcounterbored portion to secure the bridle ring to a supporting wall said enlarged head coo crating with said base to cause said shoul er portion to exert uneven pressure on the supporting wall to prevent the rotation of the ridle ring.

In testimony whereof, we have signed our names to this specification this 14th day of December 1926.
