Application'filed May 2, 1889. $erial No. 309,388. (No model.) Patented in England June 1, 1886, No. 7,852, and in France May 12,188'7,No.183,538.

T0 aZZ whom it may concern.-

Be'it known that. I, FRANK BRIDGE, corkmerchant, a subject of the Queen of Great Britain, residing at 9 Frith Street, Soho Square, in the county of Middlesex,Englarid,

have invented certain new and useful Improvements in Stoppers for Bottles and other Hollow Vessels, (for which I have received Letters Patent in England, No. 7,352, dated June 1, 1886, and in France, No. 183,538, dated May 12, 1887;) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

The invention has for its object the combi nation of a cork cylinder or other form of stopper with a head-piece or cap, as shown in the accompanying drawings, said headpiece being made of a material not hitherto used for such purpose, which material is cheap, elastic, and is capable of being firmly For this purpose- I form the head-piece or cap of the material employed in the manufacture of lincrusta Walton, which is capable of being molded into the desired form.

The material I have used and have found to answer Well in oarrying my invention into efiect is prepared from the following ingredients, and in the manner hereinafter stated; I first prepare a cement consisting of oxidized oil, fifteen pounds kauri gum, twenty pounds; resin,'fifteen pounds. The oxidized oil above referred to is preferably prepared in the manner described in the specification of English Letters Patent granted to Frederick Walton, dated January 27, 1860, No. 209, and is similar to that used in the manufacture of linoleum oil-cloth; but I do not confine myself to the said method of producing solidified oils for use, as above stated as, for instance, the solidified oils produced by long and continuous boiling at ahigh temperature will answer the purpose. When employing this latter method of solidifying oils, the articles made from composition containing the same will require to be hardened ina chamber heated to from about 100 to 120 Fahrenheit.

The method of combining the above-named materials is as follows: The oil, gum-kauri, and resin are putinto a steam-heated pan at a temperature of from 300 to 350 Fahrenheit until, under motion produced from stirrers mounted in the pan, the mass runs down into a cement similar in consistency to an adhesive dough. In the manufacture of a composition of a buif color for the purposes of my invention I preferably employ the following materials, combined in the proportions and in the manner stated: cement, prepared as above stated, thirty pounds; wood fiber, sixteen pounds; Whiting, sixteen pounds; permanent white, dry, eight pounds; paraffine-wax, two pounds;- middle chrome, one and one -half pound; orange chrome, three -fourths of a pound. The above-mentioned ingredients are mixed in a dough or roller mixing machine until thoroughly incorporated. The .color of the composition may be varied by employing other coloring-matters than those above mentioned. The composition is rolled into sheets of a convenient size and substance. Blanks are cut out of this sheet by the aid of suitable cutters, and such blanks are afterward molded in a screw or other press into the de sired form of head-piece or cap.

The construction of presses and molds suitable for the above purpose is well known. Head-pieces or capsconstruct-ed of material of the above or of similar character may be molded in position on the cork body, and

the head-piece or cap coming into contact With the edge of the bottle-neck, as,being somewhat elastic, it does not'offer an unyielding or rigid substance to the bottle-neck.

I would here remark that I do not confine myself to the exact proportions stated, as such may bevaried without departing from the peculiar character of my invention.

./ Having f ully described my invention, what I 2 desire to claim and secure by Letters Patent fiber, whiting, permanent white, parafiine- Wax, and any desired coloring material, sub- In stoppers for bottles and other hollow stantiaily as described. vessels, the combination, with a cylindrical or FRANK BRIDGE. 5 other shaped cork, of a head-piece 0r cap \Vitnesses:

composed of a cement formed of oxidized oil, B. J. B. MILLS, kanri gum, and resin, combined with wood CLAUDE K. MILLS.
