INSULA'fOR MOUNTING Filed Oct. 19, 1945 Patented May 31, 1949 UNITED STATES PATENT OFFICE.v

INSULATOR MOUNTING JohnH. Schumacher, Alma, Mo.

Application October 19, 1945, Serial No. 623,264

1 Claim. 1

My invention relates to improvements in electric fences employed for enclosures and to prevent the passage therethrough of livestock.

It relates particularly to the manner of supporting insulated electric conductors on the fence posts.

One of the objects of my invention is to provide a novel insulator supporting bracket having novel means for attaching it to a fence post.

A further object of my invention is the provision of a novel insulator supporting bracket, adapted for attaching to a fence post, which bracket is simple, cheap to make, easily installed in its operative position, strong, durable, not likely to get out of order, and which is eficient in operation.

The novel features of my invention are hereinafter fully described and claimed.

In the accompanying drawing, which illustrates a preferred form of my improved bracket,

Fig. 1 is a side View, partly in elevation and partly in vertical section of my improved bracket shown mounted in operative position on a usual fence post which is embedded at its lower end in the ground.

Fig. 2 is a top View of what is shown in Fig. 1.

Fig. 3 is a top view of the bracket.

4 is a perspective view of the bracket.

Fig. 5 is a perspective view of the locking wedge.

Fig. 6 is an elevation of the upper portion of a fence post having the bracket affixed thereto, the insulator being omitted.

Similar characters of reference ilar parts in the different views.

5 designates the usual fence post comprising two longitudinal flanges at right angles to each other, and sharpened at their lower ends. One

of the flanges is provided with transverse holes comprising horizontal slots 2 spaced one above the other at equal distances apart.

In its preferred form, my improved bracket consists of a strip of flat metal formed into a horizontal arm 3 from which downwardly diverges an inclined lower arm 4.

The ends of the arms 3 and 4 terminate in two narrowed tongues 5 and 6 that are inserted respectively through two of the holes 2. At the inner ends of the tongues 5 and 6, the arms 3 and A have shouldered portions 1 and 8 which bear against one side of the post flange having in it the holes or slots 2 next adjacent to each other.

The lower tongue 6 extends at right angles to the post I at the outer side thereof, or the side against which bear the shoulders I and 8. The

designate said lower tongue 6 has through it a longitudinal slot 9 in which is adapted to be downwardly driven a, removable wedge it the converging edges of which respectively bear against the inner side of the post and the outer end of the slot 9. This wedge i8 holds the shoulders 8 against the post I.

The upper tongue 5 is inclined upwardly from the inner side of the post, so as to hold the shouldered portions l against the post I when the wedge i9 is driven to its holding position, as shown.

For supporting a usual porcelain insulator l l on the upper side of the upper arm 3, the latter has through it, near its outer end, a hole l2 through which extends a vertical bolt !3, which extends through a wooden insulator supporting member l4 and through the insulator II. The threaded lower end of the bolt I3 has on it a securin nut 55 which bears against the under side of the arm 3.

An electric conductor l6 may be wired to the insulator l l, as shown in Figs. 1 and 2.

Washer H is disposed between the nut l5 and the arm 3.

In assembling the parts, the insulator ll, mouned on the bolt i3, is fitted at its lower end on the wooden member M, which is cylindrical at its lower end and tapering at its upper end. The bolt i3 is then inserted downwardly through the hole !2 with the lower end of the wooden member M resting on the arm 3. The nut I5 and washer l are then fitted on the lower end of the bolt 13, and the nut tightened with the washer ll bearing against the under side of the arm 3.

The tongue 5 is then inserted through a selected hole 2 in the post I, with the shoulders 1 bearing against the outer side of the post. The bracket is then swung downwardly and the tongue 6 inserted through the hole 2 next below until the shoulders 8 bear against the outer side of the post I. The wedge I0 is then inserted through the slot 9, with its converging edges bearing respectively against the inner side of the post I and the outer end of the slot 9, as shown in Figs. 1, 2 and 6, thus securely fastening the bracket to the post, with the insulator H mounted thereon in its operative position, ready for the attachment thereto, as by wiring, of the electric conductor IS. The conductor it, when charged, prevents live stock from passing between the posts, and forms with the brackets 34 and posts I an electric guarded fence -for enclosures.

As many conductors l6 and supporting brackets may be mounted on the posts, as may be needed or desired for eifectin the purpose in View.

Many modifications of my invention, within the scope of the appended claim, may be made without departing from the spirit of my invention.

What I claim is:

In an electric fence, employing a post having therethrough a plurality of transverse holes, one above the other, in combination a bracket having a horizontal upper arm and a lower arm diverging downwardly therefrom, said arms having at their ends two tongues adapted to be extended respectively through two of said holes, said arms having adjacent said tongues shouldered portions adapted to bear against one side of said post, the lower tongue having a longitudinal slot at the opposite side of said post, a releasable wedge extending through said slot with its converging edges adapted to fit respectively against said post and against the outer end of said slot, so as to ductor supporting insulator to said upper arm.
