Henry K. Ruger "self-tying" insulator patent

AN IMPROVED INSULATOR FOR ELECTRIC WIRES.

A novel form of "self-tying" insulator for electric wires, to which the wire can be readily and securely fastened, and which will prevent any accumulation of water around the wire, is shown in the accompanying illustration, and has been patented by Mr. Henry K. Ruger, of Bay St. Louis, Hancock County, Miss. It is made of a single piece of glass or other suitable insulating material, and does not require any pin, while the bottoms of the central vertical slots are curved inwardly and downwardly, so that any water or moisture entering will immediately flow out. The curves of the slots, also, are such as to facilitate the quick adjustment and secure holding of the wire. This insulator can be manufactured as cheaply as the usual forms of glass insulator in common use.
