Abstract: An end fitting with stress distribution for supporting an end of a device, such as an insulator, placed tension. The end fitting has a mounting hole for receiving a cylindrical mounting pin therethrough. The mounting hole has a pair of contacting points spaced laterally relative to the vector line of force to redirect the tensile load applied to the end fitting by a mounting pin located in the mounting hole. The end fitting is especially useful in insulators subjected to tensile loads.

Abstract: An end fitting with optimized weight for supporting an end of a device, such as an insulator, placed under tension. The end fitting has a mounting sleeve for coupling the end fitting to a core member, a mounting hole for receiving a cylindrical mounting pin therethrough and a cutout or removed portion positioned between the mounting hole and the mounting sleeve for optimizing the weight of the end fitting. The mounting hole can optionally be provided with a pair of contacting points spaced laterally relative to the vector line of force to redirect the tensile load applied to the end fitting by a mounting pin located in the mounting hole. The end fitting is especially useful in insulators subjected to tensile loads.

Abstract: A composite link and insulator, and method of construction, includes a fiberglass body. The body is formed by coating glass fibers with a liquid resin and winding the fibers around a plurality of tubular fittings or bushings in two layers, a first extending longitudinally of the body and the second transversely and around the first. A polymer shield layer and weathersheds are injection molded over the fiberglass body to create an insulator. The insulator may also be provided with stiffening plastic inserts at either end for increasing strength without adding significantly to the insulator's overall weight.

Abstract: A plastic guy wire guard which is comprised of a pair of substantially cylindrical tubular portions which are integrally joined to one another by a rapidly tapering neck portion. The design achieves substantial material savings and features a universal single sized guard for installation over any of a plurality of differently sized guy wires and associated anchor assemblies. The plastic guard may be manufactured in a continuous process which features imparting a memory characteristic to the smaller diameter portion of the guard. Upon installation, the larger diameter portion is caused to contract as a means for securing the guard to the anchor. Contraction may be caused by application of heat, either via the sun or a portable source.

Abstract: An insulating protective cover sleeve assembly for a guy wire consisting of a longitudinally slit sleeve of insulating material having an enlarged bottom end portion. In the lower end portion of the sleeve is secured a clamp, likewise of insulating material. The clamp consists of two opposing jaws integrally connected by a flexible band. The jaws are formed with two sets of different-sized opposing arcuate recesses to receive different sizes of guy wires therebetween. One of the jaws has a counterbore hole to receive a clamping screw which is threadedly engageable in the other jaw to tighten the clamp. The wall of the enlarged sleeve portion has a hole registering with the counterbored hole so that a screwdriver or Allen wrench may be drivingly engaged with the clamping screw. A channel-shaped clip engages over the top corner portions of the sleeve segments adjacent the top of the sleeve slit and is secured to one segment. The assembly allows the sleeve to expand or contract without causing distortion thereof. In a modified arrangement, clamps are provided in both the top and bottom of the sleeve, but the top clamp is loose, allowing unrestricted expansion and contraction of the sleeve. The enlarged bottom end portion may be omitted and the clamp may be secured in the normal cross-section at the bottom end of the slit sleeve.
Abstract translation: 一种由具有扩大的底端部分的由绝缘材料的纵向狭缝套管组成的家用电线的绝缘保护套套组件。 在套筒的下端部固定夹具，同样是绝缘材料。 夹具由两个由柔性带一体连接的相对的夹爪组成。 钳口形成有两组不同大小的相对的弧形凹部，以在其间接纳不同尺寸的连接线。 夹爪中的一个具有用于接收夹紧螺钉的沉孔，该夹紧螺钉可螺纹地接合在另一个夹爪中以紧固夹具。 扩大的套筒部分的壁具有与沉孔相对的孔，使得螺丝刀或内六角扳手可以与夹紧螺钉驱动接合。 通道形夹在套筒分段的顶部角部附近接合于套筒狭缝的顶部并固定到一个部分上。 组件允许套筒膨胀或收缩而不引起其变形。 在改进的布置中，夹具设置在套筒的顶部和底部中，但是顶部夹具是松动的，允许套筒的无限制的膨胀和收缩。 可以省略扩大的底端部分，并且夹具可以在狭缝套筒的底端处的正常横截面中被固定。

Abstract: An insulator link formed of an insulator body made of three blocks, each block being formed by superimposed glass fiber cloth sheets compressed together longitudinally of the insulator body; the three blocks are integrated together so that two side blocks have the edges of the sheet therein against the opposite faces of the middle block, so that the sheets in the side blocks are in planes at right angles to the planes of the sheets in the middle block; the glass fiber cloth sheets of all the blocks are loaded with dielectric resins so that the blocks can be integrated into a single cylindrical body under heat and pressure; continuous glass fiber cloth is tightly wound around the periphery of the combined blocks and is also loaded with dielectric resins so that the tightly wound cloth is integrated with the insulator body formed by the blocks also under heat and pressure; the insulator link has an axial hole therethrough, and means are provided in the opposite ends of the hole to securely hold suitable link elements.
