INSULATOR BRACKET Filed May 17, 1948 INVENTOR [SHHC HERBERT 10H SUN Patented Jan. 16, 1951 INSULATOR BRACKET Isaac HerbertJohnson, Fredericton, New Brunswick, Canada Application May 17, 1948, Serial No. 27,381 In Canada April 5, 1948 1 Claim. 1

This invention relates to an insulator bracket adapted to hold an electrical insulator in a fixed position for the purpose of insulating electric current carrying wires from a supporting body.

Wire leads must often be carried considerable distances which necessitates a plurality of insulated supports and the problem is to provide an inexpensive fixed bracket to contain the insulator. On the one hand fixed insulated supports are known but the expense of manufacturing and complexity of assembly has resulted in the rejection of such insulated supports whereever possible by organizations responsible for the erection of the wire leads. On the other hand, the common, inexpensive support presently used consists of a wire 100p into which the insulator is placed and the opposite end of the wire is fixed to the supporting body such as a tree, pole or the like. This freely swinging, type of insulated support is objectionable as the pull of the lead must be carefully adjusted to assure that the insulator will be kept free of the supporting body so that the lead will not be grounded or damaged by the I i said supporting body.

, The present invention contemplates a simple wire bracket which is bent around a conventional annular insulator and is secured to the supporting body to provide a fixed support. Thus the invention has among its principal objects the provision of an inexpensive, light, easily transported insulator bracket which will provide a fixed support for insulators of the type adapted to carry telephone or electrical wires for treeline or similar constructions.

Referring to the drawings:

Figure 1 is a perspective view of the preferred embodiment of the bracket in condition for assembly.

Figure 2 is a side elevational View of the preferred embodiment of the bracket in the assembled and erected position.

Referring more in detail to the drawings in which similar reference characters designate corresponding parts throughout the several views it will be seen that the invention, in its preferred form consists of a relatively heavy gauge, anticorrosive wire capable of withstanding climatic conditions and normal strains to which it will be subjected. The wire is of a predetermined length which is bent back on itself at each extremity and twisted to the stock at If! to form an eye II. The stock is extended for a predetermined distance in single, untwisted condition as indicated at I2.

The complementary portions of the wire, each consisting of the parts IE), I I and I2, are arranged in spaced, parallel relationship, to form two arms which stand perpendicular to, and are spaced apart by, the central basal portion of the wire designated at 3.

The remaining, intermediate portions of the wire stock are each bent back on itself and twisted to form lateral basal extensions l4, each of which terminate at an eye l5. The twisted portion I4 extends from the said eye I5 to the point of joinder of the arms to the base as indicated at It.

As seen most clearly in Figure l, the fabricated wire takes the finished form of two, parallel, spaced apart arms each of which terminate at an eye H. The said arms stand perpendicular to a base consisting of a central portion and lateral extensions, all in the same plane, each of the lateral extensions terminating at an eye A conventional insulator 20, provided with the usual marginal groove 2| and central opening 22 for the wire 23 is located between the upstanding arms and rests on the central portion [3;

each arm is then bent over the top of the insulator 20 so that each eye H of the said arms is located immediately over the opposite eye I5 of the laterally extending basal portions.

A staple 24 or other securing means is then passed through each pair of the eyes ll and I5 into the body on which the bracket is mounted. The insulator is thus tightly held between the coacting arms and the central basal portion and the arms and laterally extending basal portions are secured to the supporting body.

Although the bracket is preferably adapted to receive an insulator of a predetermined size,

it is apparent that it will function efficiently in association with insulators of slightly greater or lesser size. It is also apparent that although the wire fabricated in the manner illustrated and described herein is the preferred form of the invention, modification may be resorted to without departing from the spirit of the invention as defined in the appended claim.

I claim:

An insulator bracket consisting of a single length of wire bent to form a base portion having an eye formed at each extremity of the base portion and a pair of parallel, spaced apart, arms upstanding from the base portion and inward from the extremity of the base portion and an eye formed at the free extremity of each arm, the said arms being adapted to bend overan insulator disposed between the arms so that the eye on the extremity of each arm 1iesover the file of this patent:
