ELECTRIC INSULATOR.
SPECIFICATION forming part of Letters Patent No. 428,545, dated May 20, 1890.
Original application filed November 4, 1889, Serial 110.329,] 74. Divided and this application filed January 24, 1890 Serial No. 338.027. [Nomodeld To all whmn it nwty concern.-
Be it known that I, EMERY ANDREWS, of Kennebunk, in the county of York and State of Maine, have invented certain new and use- 5 ful Improvements in Insulators, of which the following, taken in connection with the accompanying drawings, is a specification.
The subj cot-matter of my present invention is a division of another application of mine filed November 4, 1889, Serial No. 329,174, and relates to insulators for use in connection with electrical apparatus; and it consists in a molded and vulcanized insulator composed of an inner core of solid leatheroid or other strong insulating material and an inclosingcovering composed of a mixture of ground or comminuted leatheroid and rubber thoroughly intermingled.
Figures 1 and 2 of the drawings are respectively a plan and a central section of an insulator illustrating a form of my invention adapted for use for insulating a column or standard from its supporting base-plate.
In the production of insulators I use the composition which forms the subject-matter of my before-cited application, mold it to the desired shape while in a plastic state, and vulcanize the same.
In some cases where extra strength is required, I form a solid inner core a of some strong non-conducting material, preferably leatheroid, inclose it in a covering or envelope b, composed of a mixture of ground or otherwise finely-commiunted leatheroid and rubber, mold it to the desired shape, and then 3 5 vulcanize it.
These insulators will be made of different shapes, according to the places where they are to be used, and can be furnished at a much less cost than hard rubber, are stronger 40 than hard rubber, and have very nearly, if not quite, as good insulating properties as hard rubber.
IVhat I claim as new, and desire to secure by Letters Patent of the United States, is 5 A molded and vulcanized insulator com posed of a solid inner core of some strong insulating material, as leatheroid, and an inclosing covering or envelope composed of a mixture of ground or comminuted leatheroid 5c and rubber thoroughly intermingled.
In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, on this 18th day of January, A. D. 1890.
EM ERY ANDREWS.
