4 Claims. (Cl. 24129) This invention relates to supports and, more particularly, to supports for attaching electrical wires to a building, pole, or other support.

The support disclosed herein constitutes an improvement over prior devices of this class.

It is an object of the invention to provide an improved support for electrical wires.

Another object of the invention is to provide an improved support which is simple in construction, economical to manufacture, and simple and efi'icient to use.

With the above and other objects inview, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawing and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing:

FIG. 1 is a perspective view of the support according to the invention attached to a building;

FIG. 2 is a top view of the support according to the invention;

FIG. 3 is an isometric view of the support according to the invention;

FIG. 4 is a view similiarto FIG. 3 showing the support and an electrical conducting wire laced through the slots and recesses of the stay; and

FIG. 5 is an isometric view of a stay comprising another embodiment of the invention.

Now with more particular reference to the drawing, the support or bracket shown may be referred to as a stay and has especially utility in attaching electrical conductor wires to buildings, poles, and other supports. The say is basically made up of an elongated body having a lug 18 attached to one end with laterally extending slots 22, 23, 1 22, and 123 extending more than half Way through the body. At least one of the'slots extendsin from one side and another slot adjacent thereto extends in from the other side more than half way to the other so that an electrical wire can be inserted in the slots in the manner shown with the center of the wire generally coextensive with the axial center line'of the stay. The body can be made of one integral piece with the lug attached integrally to one end. It could be injection molded from a suitable plastic material, such as, for example, nylon and the nylon could be filled with glass fiber to provide greater strength and rigidity.

In the preferred embodiment shown in the drawing, the elongated body 10 has the lug 18 integrally attached to one end. The body has two fiat sides 14 and 15 disposed parallel to each other. The body also has two flat edges 16 and 17 disposed parallel to each other and at right angles to the sides 14 and 15 and parallel to the longitudinal axis 38 of the body. The body is generally rectangular in cross section and defined by the fiat edges 16 and 17 and the flat sides 14 and 15.. The body terminates in the flat end 31.

The lug 18 is considerably thinner than the body and it has'two sides 19 and 20 which are disposed in planes generally parallel to the fiat sides 14 and 15. The lug 18 is radiused at 32 where it joins to the body to provide a pleasing appearance and a rigid design and to prevent United States Patent 0 a stress concentration at this point. The hole 21 is formed in the lug.

Slots 22 and 23 are formed in the body that extend from opposite sides therefrom as shown. The slots are referred to as first slots 22 and second slots 23. The first slots 22 extend into the body from one side past the center line 38 a distance greater than half the diameter of wire 36 and the second slots 23 extend into the body from the opposite thereof past the center line 38 a distance greater than half the diameter of wire 36. The first slots 22 are made up of first slot elements 24 and the second slot elements 25. The second slots 23 are made of first elements 26 and second elements 27. The first slots are referred to as first slot means and the second slots as second slot means. Thus, the first slot means and the second slot means can each be made up of a single slot or a plurality of slots.

One of the first slots 22 is disposed adjacent the lug and another is disposed on the opposite side of one of the second slots 23. It will be noted that the first slot element 24 of the first slots 22 extends at an acute angle to the flat edge 16 and the first element 26 of the second slots 23 extends at an acute angle to the flat edge 17.

First recesses 28 are formed between the first slot 22 adjacent the lug and the second slot 23 adjacent thereto. Second recess means indicated at 29 are formed between the second slot 23 and the next first slot 22 and, likewise, another recess indicated at 28 is formed between the next first slot 22 adjacent the end 31 and the next second slot 23 adjacent thereto. A recess 35 extends from the second slot 23 adjacent the end 31 to the end thereof. The recesses 28 and 35 are of a depth equal to at least half the diameter of wire 36.

It will be noted from FIG. 4 that the conductor wire 36 may be laced through the recess 35 and into second slot 23 by sliding it into first element 26, then through first recess 28 and into first slot 22 passing through the recess on the opposite sides thereof. Thus, with the conductor wire 36 laced through the stay as shown, it will be rigidly held in position.

It will be noted that the bottoms of the slots at 37 are radiused to conform generally to the circumference of the wire and that the wires overlay each other; that is, extend beyond the center of the stay a distance greater than halfthe diameter of the wire so that the conductor wire will lie in a straight line as it passes through the stay and be disposed adjacent the central axis 38 of the body.

In the embodiment of the invention shown in FIG. 5, the body is similar in configuration to the body shown in the first four figures; however, the lug 118 is attached to the side of the body between the first slot 122 and the second slot123. Recesses 128 are formed in one side of the body and a similar recess will be formed between second slots 123 and first slots 122 at the center as in the other embodiment of the invention. A similar recess is formed in the end. The edges 116 will be generally parallel to the edges 117 and, likewise, the sides 114 will be generally parallel to the sides 115.

The foregoing specification sets forth the invention in its preferred practical forms but the structure shown is capable of modification Within a range of equivalents without departing from the invention which is to be understood is broadly novel and is commensurate with the appended claims.
