JOHN A. EDES, OF LAWRENCE, MASSACHUSETTS.

BOTTLE-sToPPER.

SPECIFICATION forming part of Letters Patent No. 418,706, dated January *7, 1890. Application filed October 30, 1889. `Serial No. 328,624. (No model.)

To .all whom' t may concern:

Be it known that I, JOIN A. EDES, a citizen of the United States, residing at Lawrence,

`in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Bottle-Stoppers, of`

which the following is a full, clear, and exact specification.

The invention relates to the class of laterally-expansible Stoppers for bottles, cans, and jars; andthe object is to provide a stopper of this class which is cheap, few in parts, easily operated to tightly seal or unseal the mouthof the vessel into which it is inserted, safe against accidental removal, and sol constructed that no metallic or corrosive substance comes in contact with the contenta of the vessel sealed. y

In the accompanying drawings, where the invention is illustrated, Figure l is a side view of the neck of a bottle sealed by my improved stopper. Fig. 2 is a View of the same in central verticalsection. Fig. 3 is a plan view. K

In the views, the letter a denotes the neck of a glass bottle in the mouth of which one of my improved Stoppers is inserted. This stopper consists of a tapered core b, usually formed of metal, which is preferably threadedV from end toend of the tapered portion and provided at the smaller end witha handle or thumb and finger piece c. .The body d of the` stopper is formed of any expansible and somewhat elastic m aterial-as rubber-which vis suitable for eorking a bottle, and this body, which is cylindrical, is molded, cast, or otherwise placed about the core b. A head e may, if desired, be formed on the upper end of the body to prevent the stopper from being driven too far into the mouth of the bottle is inserted in the mouth of the bottle, can, or

jar which it is intended to seal and the handle rotated alittle, so that the screw is slightly drawn from the body, which, as the tapering threads move upward into the body of the Stopper, where there is more material and a smaller opening for the screw, causes the body to expand laterally or radially of the 'threads and tightly fill and seal the mouth of p ward the stopper is readily pulled out by the handle, should the-sides stick or adhere to the bottle, as the larger end of the core is at the inner end of the stopper and of course cannot be pulled out of the body of the stopper. sion of the body is overcome byfso turning the handle of the core that it is screwed farther out of the body, so that the larger end of the core is brought up to where there is more material in the body. and the life of the stopper is much longer than prior Stoppers on account of this fact.

I claim as my inventionl. A bottle-stopper consisting of an eXpansible body and a threaded tapering core having a handle at the smaller end, substantially as specified.

2. A bottle-stopper consisting of an expansible body provided with a head to prevent too far insertion into a bottle, and a threaded tapering core incased within the body and having a handle attached to the smaller end, whereby the core may be rotated ,substan tially as specified.
