. CGMPGSlTiCN FOR ELASTIC WAfiHERS.
SPECIFICATION forming part of Letters Batent No. 664,998, dated January 1, 1901.
Application filed July 3111900. Serial No, 25,420. (No specimens.)
To all whom it may concern.
Be it known that I, EWALD GOLTSTEIN, a subject of the Emperor of Germany, residing at Cologne, Germany, have invented a new and Improved Composition for Elastic Washers, of which the following is a specification.
The object of this invention is to produce a washer which is to be mainly used in metallic or other vessels having metallic lids, but which may be used also wherever metallic surfaces are to be cushioned. Heretofore india-rubber rings or cushions were employed for this purpose; but the difficulty withthem was that after some time the lids or metallic parts became black at the place where they met the india-rubber ring, forming at that When fruit-jars having thus provided with india-rubber rings, the injury to the contents of the jar was at once apparent. The cause of this deleterious action is the presence of sulwhich produces in contact with iron suliid of iron, such sulfid of iron being formed at all places where the tin or varnish coating of the sheet-metal lid has become cracked and wherever, in fact, the iron touches the india-rubber.
My invention consists in a composition which shall have the elasticity and durability of india-rubber without the presence of sulfur.
My composition consists of the following ingredients, to wit: twenty parts, by weight, of crude india-rubbcr; sixty-seven parts, by
weight, of talc; ten parts, by Weight, of asbestos; three parts, by weight, of gntta'pe cha. These ingredients are mechanically mixed until they form a tough substance and then pressed and formedlinto sheets and rings or washers out from such sheets and placed wherever metallic surfaces are to be cushioned.
I of course do not limit myself to the exact proportions of the ingredients hereinabove mentioned, because substantially the desired results may be had even if somewhat more or less of one or other of said ingredients be used. The gutta-percha is employed for the reason that it will adhere to the metallic cover with "a little heating, and the tale is employed because it is unattackable by ordinary acids contained in fruit.
What I claim is 1. A. composition for an elastic washer or cushion, consisting of crude indie-rubber, talc, asbestos and gutta-percha in about the proportions specified 2. A solid composition as described comprising gutta-percna, a gum, and a fibrous binder.
3. A solid composition consisting of an unvulcanized mass of rubber, gutta-percha and a fibrous binder.
