WILLIAM J. HISS, GE NEW YORK, N. Y., ASSIGNOF, TO DIAMOND EXPANSION BOLT COMPANY, OF NEW YORK, N. Y.,

A CORPORATION OF NEW YORK.

CABLE-CLAMP.

Application filed February 14, 1919.

To all whom it may concern:

Be it known that 1, WILLIAM J. I-Irss, a citizen of the United States of America, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Cable-Clamps, of which the following is a specification.

My invention relates to cable clamps which are used particularly to support cables along the face of walls, fences or any other suitable supports, and which while securely holding the cable do not injure or mar it.

My invention relates to such a cable clamp which can be manufactured at minimum cost out of comparatively light weight material yet one which will meet, with a wide margin of safety, all strains and stresses which may be thrown upon it under an abnormal load. Preferably though not necessarily I make my cable clamp out of a single integral piece of sheet metal of minimum thickness to reduce the cost of manufacture, and the amount of metal used.

My invention further relates to the combination of such a cable clamp with a bridle ring which may be used in some positions, where it may be desirable to support a wire in addition to the cable.

My invention further relates to certain details of construction which will be more fully hereinafter described and pointed out in the claims.

Figure 1 is a vertical section through my clamp and a cable substantially on the line 11 of Fig. 2 looking in the direction of the arrows;

Fig. 2 is a front elevation;

Fig. 3 is a plan view of a blank from which I preferably form my cable clamp;

Fig. 1 is a vertical section showing a modification in which a bridle ring is used;

Fig. 5 is a vertical section of a modification substantially on a line 55 of Fig. 6 looking in the direction of the arrows;

F 6 is a front elevation partly broken away;

Fig. 7 is a fragmentary sectional view of a modification.

In my invention I form the cable clamp 1 of comparatively thin metal so as to save material. This clamp is provided with a hook portion 2, a base 3, a reinforcing member 4, and one or more wings 5-5. The

Specification of Letters Patent.

Serial No. 277,002.

reinforcing member a is preferably, though not necessarily, formed integral with the clamp 1.

In my preferred construction I take a blank of sheet metal 6 Fig. 3, and bend it by hand or machine on the line 8 so that the portion 7 of the blank is curved to form the hook 2 of the complete clamp. The portion 9 of the blank is bent substantially at right angles to the hook portion 7 so as to form the base 3 of the complete cable clamp. lVhen the clamp is formed of a single blank it is again bent on the line 10 so that the portion 11 can be bent back on the portion 9 to make the reinforcing member l of the complete clamp. This portion 11 has its two side members 12.12 bent out substantially on the lines 13-13 to form the wings 5-5 of the complete clamp. When the blank is stamped, or subsequently, it may be provided with registering holes 1 l1l for the reception of the wood screw 15 or other securing means to hold the clamp to the wall or other support 28.

The cables are quite heavy and throw a considerable shearing strain upon that portion 17 of the cable clamp 1 where the book 2 and base 3 meet. To compensate for this heavy strain the ordinary form of cable clamp is made of comparatively heavy material throughout. This is a considerable waste of material and adds materially to the cost. By my invention I reinforce the cable clamp along the line 17 by bending out the wings 55 of the flap 4c. The ends 18-18 of the wings 5-5 form a saddle upon which rests the bottom portion of the hook member 2. The weight of the cable 16 resting pen the saddle thus formed transmits the strain through the wings 5-5 and reinforcing member 4 directly to the wood screw 15 or other securing means, and prevents the hook 2 from sagging, bending or being out along the meeting surface 17 between the hook 2 and base 3. WVhile I have shown the reinforcing member 4 as an integral flap of the base 3 it is of course to be und rstood that it may be a seoarate member 30 if desired as shown in Fig. 7.

In some instances where it is desirable to supportatelephone wire 19. in addition to the cab e 16 I may use a bridle ring 20 screwed into the lower portion of my cable clamp as shown in Fig. 4. The advantages of sunporting a telephone wire by such a bridle ring and from a single cable clamp or clip is described in full in my United States Letters Patent 792,594 dated June 20, 1905. While I have shown such a bridle ring in connection With my improved cable clamp it is to be clearly understood that my invention is not to be confined to my cable clamp being used in combination With such a bridle F1110.

'fo further strengthen my cable clamp I may in some instances, as shoWn in Figs. 5 and 6 form a reinforcing rib 21 on the hook portion 22 of the cable clamp shown in these figures. In this modification the flap 24 has its end notched at 25 to receive the rib 21. This'flap 24: is preferably bent from the base 26 and provided With Wings 27, 27 the same as in the construction previously described.

Having thus described this invention in connection With illustrative embodiments thereof, to the details of which I do not desire to be limited, What is claimed as new and What is desired to secure by Letters Patent is set forth in the appended claims.

What I claim is:

1. An article of manufacture comprising a cable clamp having an integral hook, base, and flap bent back on the base said flap being provided With one or more Wings bent at an angle to the flap and adapted to reinforce the junction of the hook and base portions of the clip.

2. An article of manufacture comprising a cable clamp having a hook portion, a flat base, a Hat reinforcing member lying against the base, and one or more Wings on the flat reinforcing member adapted to contact With the hook portion and thereby reinforce the junction of the base and hook portions.

3. An article of manufacture comprising a cable clamp formed of sheet metal having a hook, a flat base and a saddle or support lying against the base and having a portion formed at an angle thereto and being of sufficient length for its end to bear against the hook portion at a point removed from the junction of the hook and base portions.

4-. An article of manufacture comprising an integral cable clamp formed of sheet metal having a base, a hook, and a reinforcing member adapted to lie against the base and contact With the hook to take and transmit most of the bending and shearing strains from the hook, said reinforcing member being bent out and put under compression by the said bending and shearing strains thrown on the hook by the cable.
