UNITED STATES PATENT OFFICE.
JOHN FO'ITRELL, OF PHILADELPHIA, PENNSYLVANIA.
INSULATING MATERIAL.
SPECIFICATION forming part of Letters Patent No. 433,893, dated August 5, 1890. Application filed December 23, 1889. Serial No. 334,738. (No specimens.)
To all whom it may concern:
Be it known that 1, JOHN FOTTRELL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Insulating Material; and I do declare the following to be a full, clear, and exact description of the inventi0n,such as will enable others skilled in the art to which it appertains to make and use the same.
My invention relates to the insulation of electrical conductors; and its objectis to obtain an insulating material which is substantially equal to rubber, but' which is cheaper, firmer, and more durable than rubber, and which does not require vulcanization. I attain this object by thoroughly mixin'g together in any suitable manner indiarubber and aluminum oleate. Aluminum oleate is best prepared by precipitating a solution of sodium oleate or soap with a solution of aluminum sulphate or alum, expressing the water from the spongy precipitate, and then drying it at a moderate temperature. Palm-oil soap is best for this purpose, and in general the perfection of the resulting composition depends on the purity of the ingredients, though I have found that any form of rubber may be used, provided that it is thoroughly mixed with the aluminum oleate. YVhen so mixed, the compound is homogeneous, and experiment indicates that under the action of the electric current it improves in quality and its insulating resistance is in-' Having thus fully described my invention,
what I claim, and desire to secure by Letters Patent, is
An insulating material for electrical conductors, consistingof a mixture of india-rubher and aluminum oleate, substantially as described.
In testimony whereof I affix my signature in pressure of two witnesses.
JOHN FOTTRELL.
