SPECIFICATION forming part of Letters Patent No. 539,429, dated May 21, 1895.

Application filed March 6, 1895.

To all whom it may concern:

Be it known that I, CHARLES HUGH, of Hoboken, Hudson county, New Jersey, have invented an Improved Bottle-Stopper,of which the following is a specification.

This invention relates to an improved internal bottle stopper by which the contents of the bottle are protected entirely from contact with the spring wire that holdsthe stopper in position.

The accompanying drawing represents a vertical section of my improved bottle stopper.

The letter a, represents the porcelain body or plug of the stopper which is divided into an upper and lower head or section by a peripheral groove a. This groove is adapted to receive the annular rubber gasket 17, that is forced against the neck A, of the bottle A, and thus forms the seal. The upper head a of the plug a, is of smaller diameter than the lower head a, so that the gasket b, can fold around such upper head as the stopper is pushed into the bottle. Through the plug a,

extends partially an axial tapped socket a, which however does not penetrate the plug but passes only about half way through the This socket is adapted forthe lower head a.

Serial No. 540,713. (No model.)

reception of the lower threaded end'of the bent spring wire 0, by which the stopper is held in position. Thus the lower end of the wire is entirely out of contact with the contents of the bottle and the latter cannot possibly be injuriously affected thereby.

The stopper is used in the ordinary manner, being pushed down (dotted lines), when the bottle is to be opened and being drawn up (full lines) when the bottle is to be closed.

The advantages connected with my improved stopper areits simplicity of construc- CHAS. HUGH.
