Application ottom- 27, 1944, Serial No. 566,842 r My invention rela to improvements in insuand supports for electrically charged fence The object whereby and support having theabove specified characteristics and which is aim peculiarly adapted for Pigurelis a perspective view of my connector, showing the same in wire supporting relation to post of T-shaped cross section,

a fragment of which is also illustrated.

ted margin of the bar with a. wide flat surface, 3.

z cl ms; (c1..174 '1ss) preferably interposed between the 4 2 A generally cylindrical porcelain insulator knob I1 is axially portion of the yoke member M, a washer l 9 being head of the screw and the outer end of the knob H. The threaded portion of the screw is provided with a clamping nut 20 engageable with the inner face of the yoke member l4, whereby the Another washer 2| may be interposed between the knob I! and the member 14, and will preferably be of a resiliently yielding type.

With the nut 23 properly adjusted to allow a sufficient retraction of the screw in the yoke, the latter may be readily slipped over the upper end of the fence post and moved downwardly to the desired elevation. Thereupon the nut 29 working in this industry to perceive the necessity of providing against faulty installation by inexperienced persons, and of providing a structure which in each of a multitude of instances will be uniformly attached to each fence post with the necessary rigidity and identity of projection, and which can be installed at such minimum expense as to eliminate the temptation to resort to other means.

In Figure 3 K have illustrated a slight modification. The fence post is of a type in which the rib i2 is omitted, but this is immaterial since the conector may be applied to either type of fence post with equal "facility. However, the yoke is made with a thickened apertured portion ltd,

and the aperture is threaded to receive a clamping screw idea, the nut 2d being omitted. But a thumb nut dis is provided near the outer end of the screw in a position to bear upon a washer 59a interposed between the thumb nut and the insulator knob. With this construction, after adjusting the yoke to a fence post, a screw driver may be employed to turn the screw in a direction to clamp the yoke to the fence post, after which the thumb nut 39 may be adjusted to apply the desired clamping pressure to the knob lla. With this construction, none of the parts need be resilient, since independent means are employed to clamp the post and the knob to the yoke.

it will be observed that the portion i l (or Ma) of the yoke is substantially parallel to the laterally extending flanges, and the clamping bolt or screw is substantially parallel to, or in, the central plane of the post member or bar iii. Therefore the conector is secured to the post in a symmetrical position from which it cannot be readily dislodged by any form of pressure to which fence posts or wires may be subjected.

I- claim:

1. Means for securing electrically charged bare fence wires to metal posts having flanges extending laterally in oppos'te directions from the central portion of the post, comprising the combination of a yoke-shaped member having resilient arms provided with free and mutually spaced hook-shaped extremities adapted to loosely embrace the outer margins of said flanges and to move downwardly along said margins from the top of the post to the fence wire level, a clamping bolt extending through the central portion of said yoke-shaped member and having thread.- ed engagement therewith, an annularly grooved wire supporting insulator knob through which said clamping bolt extends along the axial line of said knob, said clamping bolt being adapted when turned in one direction to clamp said knob to the yoke-shaped member and to also clamp the yoke-shaped member to the post under the resiliently yielding tension of its arms.

2. an insulator mounting for attaching the conductors of electrical fences metal posts which are T-shaped in cross section, said mounting comprising the combination of a yoke-shaped member having resilient arms protided with 5. ac and mutually spaced hook-shaped extremities adapted to embrace the post, a clamping belt extending through said member and having thrust engagement therewi h, said bolt having a portion for engagement with a post with which such extremities are also engaged, and an insulating knob through which such bolt extends, said knob being confined under pressure by said bolt and member, the single bolt serving to clamp the knob to said member and the member and knob to the fence post.
