CABLE AND WIRE CLAMP.

Specification of Letters Patent.

Patented July 8, 1919.

To all whom it may concern:

Be it known that I, GABRIEL E. ROHMER, a citizen of the United States of America, and a resident of Elmhurst, Long Island, New York, have invented certain new and useful Improvements in Cable and Wire Clamps, of which the followin is a specification.

This invention re ates to improvements in and relating to cable and wire clamps, and more particularly to that type which are used for the purpose of supporting and hanging cables, Wires, ipes, etc., along the Walls of buildings, anf whlch are fastened to the walls by means of expansion bolts, screws, nails, or other suitable fastening means. An object of the invention is to provide an improved form of clamp or sup ort of this character which may be readi y manufactured at a comparatlvely small cost, which may be easily installed, and when installed be immediately in place for use, and so constructed that the cables or wires may be readily removed at any time when it is desired to renew the same, or for other purposes, and the clamp will remain anchored fast to the wall and in a osition so as to be ready for further use. further object is to provide in such a device supporting means whlch will be free of any sharp corners, so that there will be a minimum of wear upon the arts supported.

ith these and other objects in view, my invention is shown in the accompanying drawings, and will be hereinafter more fully described with reference thereto and finally pointed out in the claims.

In the accompanying drawings,

Fi re 1 is a perspective view showing one orm of my invention in supporting position upon a wall, and showing a cable and wire supported thereby;

Fig. 2 is a perspective view of a modified form of construction;

Fi 3 is a perspective view of a further modi ed form of construction;

Fig. 4 is a perspective view of another modified form of construction;

Fig. 5 is a perspective view of a modified form of construction somewhat similar to that shown in Fig. 1 but with the wiresupporting means in a different position;

Fig. 6 is a side view of a still further modified form; and,

Fig. 7 is a front elevational view thereof.

Similar reference characters indicate cor responding parts throughout the several figures of the drawings.

Referring to the drawings, and more particularly to Fig. 1 thereof, my improved clamp or support is constructed of a blank of sheet metal, such as strap-iron or the like, which is provided with an aperture 10 in the intermediate portion 11 thereof, a screw 12 or other fastening means, such as an expansion bolt or the like, bein secured throu h the said opening for holdmg the support 1n place upon the wall. The upper portion of the clamp is bent upwardly and outwardly from the said intermediate portion to form a curved hook-shaped portion 13, in which the cable 14. or the like is held in position. The sides of the clamp are cut inwardly below the said intermediate ortion 11, as at 15, to form a relativel t in downwardly extending member 16, t e contour of which is preferably beaten into rounded shape, and which is bent upwardly upon itself to form a ringshaped wire-supporting portion 17, and in which are supported the wires 18 or the like. The end of the said member 16 is preferably turned to one side of the body portion of the clamp, as at 19, so'that there will be no sharp corners to Wear upon the insulation of the wires. The material used in constructing my improved clamp is of suitable flexibility to enable the same to be readily sprung open, so that the parts sup orted may be removed and replaced when esired.

In the embodiment shown in Fig. 2, the clamp is used in inverted position from that shown in Fig. 1, the Wire-engaging portion 20 being at the upper end of the intermediate portion 21, and the cable-supporting member 22 being at the lower end thereof and bent outwardly and upwardly therefrom, the same being hook-shaped and bent slightly inwardly at the end, so that the cable is held securely therein.

In the form of construction shown in Fig. 3, the cable-supporting hooked portion 23 at the lower end of the intermediate portion is split, as at 24 and 25, to form a central tenchanhellsliapedftlie' rounded portion thereof and normally t inner surface of the said central portion is sli htly within the inner surface of the hooker portion. In other re spocti-l the parts of this embodiment of my improved clamp are substantially the same as the construction shown in Fig. 2, with the exception that the hookedportion 43 instead of being of rounded contour is being on the inner or wire-engaging side. The advantage of this construction is that the. tension member 26 secui ely holds the cable within the hooked portion and serves as a guiding means for inserting the said cable t erein, also permits read removal o .t e same by springingthe sai central portion outwardly by exerting pressure on the upper end thereo In Fig. 4, I have shown a still further modified form of construction, in which an aperture 27 is provided at the upper end of the clamp for securing the same to the wall, and the lower end thereof is bit ircated cen trally, as at 28, one side thereo being bent upwardly to form a hooked portion 29 for support ng the cable, and the other side thereof. rounded and bent upwardly .upon itself tp forhi a wire-supporting member 30, said w re su pporting member being beneath the saidcable-s porting hooked portion 29.

In the form s own in Fig 5, an aperture 31 is provided in the lower portion 32 thereof for securing the same to the wall, and the upper portion is bent outwardly and upwardly therefrom to form a hooked portion 33 for supporting the cable. This hooked portion is split, as at 34 and 35, and the intermediate. pogtionjs oarried straight upwardly erefrom and rounded and bent downvrmrdlg upon itself to form a wire-supporting member 36 This form of construction is somewhat similar to that shown in Fig. 1; with the exception that the wire-supporting, member is arranged above the cablesupporting member instead of below the same, asin the construction shown in Fig. 1.

In Fi e. 6 and 7, I have shown a still further mo ified formoficonstruction, in which the intermediate portion 37 is proyided with an aperture 38 in the form of construetion shown in Rig. 2, and a wireoapporting member 39 is provided above the same, this member insteedof being rounded as in Fig 2 being in the form of a semicircular chem nel 40, the convexnportion thereofbeing on the inner side; so that there is no sharp. surface for wearing. upon the insulation ofthe wires. The lower rtion of the clamp is bent outvvardlg an downwardly from the said intermediate portion 37 to form a hooked supportingfmembei 4i, and semicircular channels 42 are provided along the edges thereof, the rounded surface being on the inner side thereof, so that there are no sharp surfaces for wearing upon the insula tion of the cable.

In Fig; 7, is clearly shown the manner in which t e wire-en'agin portion is bent obliquely upon itsel so t at its end is disposed at one side of the central portion thereof. This construction permits of the ready insertion and removal of the wires into and out of the same. It will be seen that with the use of my improved clamp, a very inexpensive and at the same time efiective meansfor supporting cables and wires in position is provided and by which there will be practically no wear upon the arts supported, and the same may be rea ily removed and replaced when desired without in any way changing the position of the supportlng members or defacing the building.

I have shown preferred and satisfactory forms of my invention, but it is obvious that changes may be made therein within the spirit and scope thereof, so that Ido not desire to be limited to the form shown, except as may be required by the claims.
