    摘要： A method and device for anchoring rods of high tensile strength insulating material in metal attachment fittings are disclosed. The end of the rod which is previously split and traversed by a hole is inserted axially into the attachment fitting through an open end thereof. A fastening member is inserted into a blind hole extending across an internal cavity in the attachment fitting in line with the hole in the rod for spreading the rod end, the split end being brought into engagement with large wall portions of the inwardly flaring internal cavity of the attachment filling. A relatively high vacuum is applied to the internal cavity. The internal cavity is filled with a high strength, nonshrinking resin having a coefficient of expansion identical to that of the metal fitting through a channel in the fastening member. After polymerization the resin hardens on the rod to form a rigid block fast with the attachment fitting which prevents the rod from being pulled out of the attachment fitting. The protruding end of the fastening member is then severed level with the exterior of the attachment fitting.

    摘要： A cylindrical porcelain insulator having a depressed opening in at least one end thereof is utilized as a support member. An elongated steel stud having a threaded end and an enlarged securing end is disposed in the depressed central opening of the porcelain insulator. The enlarged securing end has circumferential lateral ridges and depressions for providing an enlarged surface area. Babbit or epoxy material is disposed in the remaining volume of the depressed opening. The securing end of the stud is therefore suspended in the hardened babbit or epoxy material, which in turn is affixed to the sides of the depressed opening, thus affixing the stud to the insulator. The stud has a relatively flat circumferential lateral shoulder at the upper end thereof which protrudes above the end of the insulator and out of the depressed opening. An electrical bus bar or bus bar retaining apparatus is disposed around the threaded portion of the stud to rest on the flat shoulder in a flat surface to flat surface relationship. Fastening means, such as a nut, is threaded onto the stud and torqued against the bus bar or bus bar retaining apparatus. The torquing stress provided to the bus bar is directed against the flat shoulder rather than the babbit material. When the bus bar or bus bar assembly has been thus secured to the stud with a predetermined amount of torque, the bus bar assembly will remain reliably affixed in place at that value of torque over a relatively long period of time and even when exposed to significant variations of temperature.

    摘要： Method of cementing together the cap, body and stem portions of electrical insulators, comprising introducing measured quantities of water and cement into the cavities of the cap and body, mixing the ingredients within the cavities and immediately assembling the aforesaid portions into a complete article. The method is particularly useful in production line procedures of producing insulators.
