UNITED STATES PATENT Orricnl \YILLIAM GEORGE BREMER, OF ST. LOUIS, MISSOURI, ASSIGNOR TO THE UNITED ELECTRIC IMPROVEMENT COMPANY, OF GLOUCESTER CITY,
NEXV JERSEY.
HIGH-RESISTANCE COMPOUND.
SPECIFICATION forming part of Letters Patent No. 443,565, dated December 30, 1890.
Application filed October 31, 1890- Serial No, 369,970. (No specimens.) I
To all whom it may concern:
Be it known that I, WILLIAM GEORGE BRE- MER, a subject of the Emperor of Germany, but now residing at the city of St. Louis, in the State of Missouri, have invented certain new and useful Improvements in High-Resistance Compounds for Electrical and Similar Appliances, of which the following is a specification.
My invention relates to the manufacture of a homogeneous high-resisting compound or composition consisting of two or more substances or materials.
The principal object of my present invention is to provide a homogeneous high-resisting composition or compound susceptible of melting, softening, or fusing at a comparatively moderate temperature, and such a composition or compound as is especially adapted for use in the making of disks, rods, bars, pellets, plugs, &c., for use in cut-outs, safety and analogous devices of electric-lighting systems.
My invention consists of a homogeneous high-resisting composition, as hereinafter described, and pointed out in the claims.
In order that my invention may be understood, I Will now proceed to describe the same.
A certain quantity or percentage of rubber is mixed or dissolved in chloroform, and to which a similar quantity or percentage of shellac and graphite is added, and the composition or compound in preferably a thick solution is then worked in a mortar or other suitable appliance until the solvent employed in the composition or compounding of the same has been evaporated, after which the mass is rolled into sheets or drawn out into rods or bars or caused to assume such other form, shape, or condition as may be required for the particular use. Having undergone the described treatment, the composition or compound, in sheets or in any other preferred form or condition, is then exposed to heat in avulcanizing apparatus for from five to ten hours, more or less, according to requirements. \Vhen the sameis removed from the vulcanizer, the composition is in a hard or rigid condition ready for its particular usefor instance, in cut-out devices and other electrical appliances.
The mass, if preferred. after being rolled or drawn out into sheets in the aforesaid manner, may undergo the vulcanizing stage of the process of manufacture before being cut up into the required form, shape, or configuration for use, and in some instances such will be found the preferable mode of manufacture thereof. Again, the composition may be com posed of equal or substantially equal proportions or quantities of rubber, sulphate of baryta, graphite, and shellac, the sulphate of baryta being added to the mass or composition for the purpose of giving solidity to the finished product and the shellac for the purpose of obviating any tendency to brittleness in the product and in order that the same Will be not only hard or rigid, but strong,
thereby permitting of the handling of the same. The composition or compound composed of the materials or substance last mentioned may then be treated in the manner de scribed for causing the same to arrive at a state or condition for use.
It is very necessary that the composition for securing the best results be composed of such substances or materials as are susceptible of being rendered homogeneous or of giving that character of a product, in order that a high resistance in use may be assured-for example, in its use in the shunt-circuit of a cut-out device of an electric lampwhen-the filament or pencil of the lamp from any cause fails to operate, such a composition in suitable form applied to such a device being ca pable of effectually causing the current through the lamp to establish a short circuit therein, or of the dynamo current to be shunted through the lamp without affecting the others arranged in the series of the system. There are many other uses to which such composition may be advantageously employed in electric-lighting appliances or apparatus, and hence I do not limit myself to its use in cut-out devices.
Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-
