J. F. VERNER RUBBER INSULATOR FOR WIRES OF ELECTRIC FENCES Filed Feb. 18, 1947 Patented Oct. 28, 1947 RUBBER INSULATOR FOR WIRES OF ELECTRIC FENCES James F. Verner, Pocahontas, Iowa Application February 18, 1947, Serial No. 729,319

1 Claim.

This invention relates to rubber insulators designed primarily for use with steel fence posts, wherein the wires of the fence supported by the post are electrically charged.

The primary object of the invention is to pro- 4 vide an insulator which may be readily and easily positioned'on a fence post, the insulator having means whereby the electrically charged wires supported thereby, will be securely held to the fence posts, the wire being insulated against grounding.

Still another object of the invention is to provide an insulator of this character which may be readily and easily positioned at various heights along the posts on which they are positioned, thereby securing fence wires at various distances from the ground surface.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts, hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed. I

Referring to the drawing:

Figure 1 is an elevational view of a fence post equipped with rubber insulators, constructed in accordance with the invention.

Fi ure 2 is a sectional view taken on line 2-2 of Figure 1.

Referring to the drawing in detail, the reference character 5 indicates the usual T-shaped post construction, the post being provided with openings 6 extending'through the main flange ofthe post.

The insulator, which is indicated generally by the reference character 1, comprises a body portion, constructed of rubber material and formed with a T-shaped opening to accommodate the T-shapedconstruction of the steel post 5.

An opening extending transversely through the main portion of the insulator, is provided for the reception of the nail 8, which nail also passes through the opening 6 of the post, which is in alignment with the opening of the insulator.

The forward portion of the insulator extends an appreciable distance beyond the face of the post 5, and is cut out to provide a notch 9 through which the fence wire, indicated at Ill, extends. The reference character I I indicates a nail which is held vertically within openings formed in insulater I adjacent to the notch, the nail closing the notch to prevent the fence wire from becoming displaced.

From the foregoing it will be seen that the fence wire which is supported by the insulator, will be insulated from the post so that the electric current passing through the fence wire will not be grounded by the post.

It will further be seen that the insulator may be readily and easily removed should it be desired to dismantle the fence and place it elsewhere.

It might. be further stated that the insulators will be made with a view to selling them as an article-of manufacture for use on fence posts new in common use in fence construction.

Havin thus described the invention what is claimed is:

An insulator for positioning on metallic fence posts. having openings in one of the flanges thereof, said insulator comprising a body portion constructed of insulating material and formed with an opening to accommodate the fence Post, said insulator having transverse openings adapted to register with an opening in the fence post. a nail extended through the openings of the insulator and aligning openings of the fence post, securing the insulator -against movement longitudinally of the fence post, and said insulator having an opening in which an electrically charged wire is held.
