A new insulator for electric wires, that embodies several points of novelty, has been patented by Mr. John P. Sharpe, of Oneida, N. Y. The body of the insulator is made of glass or porcelain, and has a central bore terminating short of the top and having offset notches. In this bore are located two stems or standards having lugs that engage in the notches and provided at their lower ends with feet which are secured to the cross bar of the pole. The outer face of the body has a transverse notch through which the wire to be supported is passed. A plate fits over this notch and has its upper end seated in a socket, the plate being held in place by a metallic ring that is slipped over the body. It will therefore be seen that there is a novel means for attaching the wire supply as well as a new form of support for the body.
