Nov, 8, 1932. H. c. sTAToN INSULATOR STRUCTURE Filed June 20, 1928 Patented Nov. 8, 1932 rumen-K PATENT OFFICE HARRY C. STATON, OF BURLINGTON, IOWA INSULATOR Application led .Tune 20,

The object of my invention is to provide an insulator structure of simple, durable, and comparatively inexpensive construction.

A further object of my invention is to provide an insulator especially adapted for use in the electric and radio iield in which novel means of connecting the wire to the insulator and of anchoring the insulator to a support is provided.

More particularly, it is my object to provide an insulator in which a body portion formed of porcelain or other suitable insulating material is provided in combin ation with an anchoring rod of irregular coniiguration, the insulator body being formed with an opening of such shape to allow insertion of the anchoring rod whereby the insulator body may be supported relative to the anchoring rod.

Still a further object is to provide in connection with the anchoring rod, an L-shaped brace adapted to prevent straightening out of the anchoring rod when the insulator structure has once been assembled.

With these and other objects in view my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawing, in which:

Fig. l is a plan view of the insulator body.

Fig. 2 is a side elevation of the same.

Figure 3 is a sectional view through the insulator body showing an anchoring rod and a brace for the insulator body.

@n the accompanying drawing, I have used the reference character A to designate generally, the body of the insulator structure. The body portion A is formed of porcelain or other suitable insulating` material and is provided with an opening 10. The opening 10 runs through the insulator from top to bottom and has a cutaway portion indicated at 12.

STRUCTURE 1928. Serial No. 286,755.

A groove 14 extends lengthwise of the body A from the opening 10 to one end of the body. An opening 16 extends through the insu lator from side to side for the purpose of receiving an electric wire or a tie wire, as the case may be. Each side edfre of the body A is grooved as indicated at 18 and one end thereof is grooved as indicated at 20.

In Figure 3 of the drawing, I have shown an anchoring rod C which is screw threaded, as indicated at 38 to receive a nut 40. The anchoring rod C may extend through a pipe 42 or any other type of support through which an opening can be provided, so that the nut 40 can be positioned on the side of the support 42 opposite the insulator A. rIhe anchoring rod C ext-ends along the insulator A in the groove 14, as clearly illustrated, and is provided with a nut 44. To prevent straightening out of the anchoring rod C, I provide a brace strap 46 made of liat material having openings punched in its ends so that the strap 46 may extend along two surfaces of the insulator A and be associated with portions of the rod C extending at right angles to each other. If desired, the brace 46 may be formed oi heavy wire having eyes proided in its ends. Vhen arranged as shown in Fig. 6, the dead ended wire 30, in the event. that the insulator A is broken, will not drop onto the ground, but will be caught by the anchoring rod C.

It will be obvious that various changes such as in the configuration of either the insulator body A or the anchoring rod C may be made without departing from the real spirit and purpose of my invention, and it is my intention to cover by my claims, any modified forms of structure or use of mechanical equivalents, which may be reasonably included within their scope.

I claim as my invention:

1 An insulator comprisinor a body portion having an opening therein, an anchoring rod having a shank and an angularly extending portion received in said opening, a substantially L-shaped brace having its ends receiving the shank and the angularly extending portions of said anchoring rod to prevent the same from straightening out and a second opening in said body portion for receiving a Wire to be anchored to the insulator.

2. An insulator comprising a body portion having an opening therein, an anchoring rod having a shank and an angularly extending portion received in said opening and a substantially L-shaped brace having its ends receiving the shank'and the angularly extending portions of Said anchoring rod and preventing it from straightening out.
