Letters Patent No. 104,794, dated Jun-c 28, 1 870.


The Schedule referred to in these nettersPatent and making cart of the same.

To all whom it may concern:

stopper constructed in accordance with my improvement, andas fitted within the mouth of a jar or bottle.

Figures 2, 3, 4, and 5, are face views of details used in the construction of said stopper.

Figureti is a sectional view of, a modification of same invention.

Similar letters of reference indicate corresponding parts.

. ,My invention consists in a novel combination of suitable materials, whereby a heat, solid, and durable stopper is produced,

In the construction of my improved stopper, when the same is to be metal bound, I first stamp out of sheet metal, a cap, A, having a hole, a, through its center, and formed with an outerturned-over border or rim, l), and inner tapering orconical-shaped eye or socket, c, that serves to receive through it, from 'tho outside, a wooden core or plug, B, of tapering or enlarged form at its back or outer end, to fit within the eye 0, so that, in drawing out or pulling on the stopper, the cap A cannot be detached ti'om the plug, which it is. desirable to dip into hot shellac prior to inserting it through the eye 0, and, after insertion, to turn. theinner edges of said eye so aslto cut into or enteran annular groove in the plug, as shown in-fig. 1. This makes a firm union of the metal cap and wooden uln the outer rim 1) of the metal cap may be also made to rcceirelwithin it a ring, 0, of wood or other suitable material, and the edges of said rim lapped or turned over to hold the ring in'plaee, as represented in fig; 1.- This gives solidit-yto the outer rim portion of the metalcap.

Shellac, or cement of any suitable kind, is then put into the cap, which is placed upon aheatcd plate, and wring, D, of cork or gutt-a-percba, but which it will suiiice here to call an annularcork, is driven onto or over the plug, from its inner end, and down into the meta-l cap, wit-bin (where such is used) the ring 0 as v a binding, and united to the cap and core or plug by the shellac orcement, to facilitate which the cork should be chamfered or tapered away on the inside, as represented in fig. 1.

This completes the stopper, though, if desired, the blank 11, which was punched out of the metal. in forming t-he hole a in the cap, may be sweated onto the latter over'the outer end of the plug B,- but such is not absolutely requisite.'

The details of construction may, in fact, be more or less modified, but, by the combination of a metal cap with a wooden core and cork exterior, the dlfliculty hereto hre experienced of-uliiting, in a dmablemanenor, a soft material like cork to a metal cap, is obvi- The same principle of construction may be carried out, and the metallic casingdispeused with, as represented in fig. 6, by forming the wooden cap 0, to cover the end of the annular cork D with-a recess, 0, for the reception of the latter on its under side, and a central orifice, n, tapering from its upper side to receive the tapering formed head of the plug or core B.

The several parts being thus formed, the annular cork Dor flexible portion is to be inserted in the recess e on the under side of the cap 0, with shellac or othersuitable cement, and the core B, which is also coated with cement, is then driven from the upper side of the cap 0 through the cork D, until its enlarged and fits closely in the tapering cavity in-the cap.

In this mode of construction, the cork being in-' serted on one side of the cap, and the core from the other side, with its tapering head fitting into the cavity in said cap, they can only be separated by loosening or softening the cement, and the cork portion, being supported by the wooden core, cannot easily be broken.

- What is here claimed, and desired to be secured by Letters Patent, is-- A bottle-stopper composed of a cap, 0, and core 15, of wood, or other solid material, and an annular collar, D, of flexible material, the-latter being inserted in the cap on its under side, and the core with its edgie-1ikc head inserted from its upper side, as set. forth, whether said cap be metal bound or not.


ated, there beingnosuch difficulty in uniting the wooden core to the metal cap, or the corkto the wooden core.
