US 4,771,137 A · Electric fence wire insulator

Abstract

An electric fence wire insulator is formed as an integral, one-piece body of non-conductive synthetic resin and includes a transverse spark shield from which extends in one direction a pair of laterally spaced main legs terminating in a pair of laterally spaced feet configured to abut the arcuate or flat surface of a wooden or metal fence post. Openings through the feet receive nails or screws by which to secure the feet to the fence post. Projecting in the opposite direction from the spark shield are five laterally spaced fingers provided with inwardly facing arcuate grooves which are aligned transversely for the reception of an electric fence wire. Laterally spaced secondary legs inwardly of the main legs are shaped to provide two pairs of split circular retainers of different diameters for the frictional retention of different size rod type fence posts. Inwardly facing sockets on the main legs adjacent the feet frictionally grip between them the laterally extending arms of a T type fence post, the central leg of which may extend into the space between the split retainers of the secondary legs. A pair of shoulders on the main legs are spaced from the spark shield to form a pair of grooves therebetween for the reception of the U-shaped mounting end of a stand-off wire the opposite of which is formed with an open loop for the removable reception of an electric fence wire.

Dependent claims

An electric fence wire insulator formed as a unitary body of electrical insulation material and defining:

(a) a transversely disposed spark shield,
(b) a pair of laterally spaced legs extending from the spark shield and terminating in foot members having surfaces disposed substantially parallel to the spark shield for abutment against a fence post,
(c) the foot members having openings through said surfaces for reception of fastener means for securing the foot members to the outer arcuate or flat surface of a fence post,
(d) a pair of inwardly facing, mutually confronting socket members one on the inner side of each leg adjacent the foot members configured to removably receive and frictionally retain therein the laterally extending arms of a T-type fence post, and
(e) wire retainer means on the side of the spark shield opposite the legs for removably securing an electric fence wire to the insulator.

(e) wire retainer means on the side of the spark shield opposite the legs for removably securing an electric fence wire to the insulator, the wire retainer means comprising five fingers projecting from the spark shield in the direction away from the legs, alternate fingers being spaced apart vertically and provided with inwardly facing, laterally aligned grooves for the removable reception of an electric fence wire, and
(f) a pair of laterally spaced secondary legs inwardly of the first named pair of legs, the secondary legs having at least two pairs of registering arcuately concave segments facing each other and forming at least two split circular retainers spaced apart longitudinally between the foot members and spark shield, the retainers being of different diameters for the reception of rod type fence posts of different cross sectional diameters,
(g) the space between the facing registering arcuately concave segments of the secondary legs being configured to removably receive therein the leg of a T type fence post.
