BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 336,848, dated February 23, 1886.

Application filed November 18, 1885. Serial No. 183,187. (No model.)

To aZZ whmn it may concern.-

Be it known that I, AARON E. FRASER, a citizen of the United States, residing at Lockport, in the county of Niagara and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers; and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to stoppers designed particularly for use in connection with bottles, casks, barrels, jars, and other vessels containing cider, beer, and like beverages or other substances which generate a gas.

The object of the invention is to provide a stopper which will, when there is an excess of gas in the bottle, cask, barrel, jar, or other vessel, automatically unseat itself to allow the escape of a sufficient quantity of the gas to prevent the bottle, cask, barrel, jar, or other vessel from breaking, and which will, when said excess is removed or allowed to escape, automatically seat itself and close the mouth of the bottle, cask, barrel, jar, or other vessel to prevent the entrance of air.

The invention further consists in the improved construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure 1 is an elevation of a bottle with my improved stopper applied thereto. Fig. 2 is a transverse vertical section. Fig. 3 is an elevation showing a modified form of spring.

Corresponding parts in the several figures are denoted by the same letters of reference.

Referring to the drawings, A represents the bottle, of ordinary construction.

B represents a metallic frame or support, which is substantially the same form as an inverted U. The lower ends of the frame B are provided with inwardly-extending nibs or the frame, midway the sides thereof, is providcd an opening, a. v

0 represents a rod, which is located in the opening a, and on the upper end of said rod or bar is a swiveled finger piece or bar, 6, by means of which the bar may be raised. If a bar is employed, it will be seen that when not in use it may be turned so as to occupy a position on a line with the upper end of the frame, and when needed may be turned at right angles thereto, so that it may be readily grasped, and thus allow the bar to be easily raised. Upon the lower end of the rod 0 is formed an annular shoulder or ledge, 0, upon which is fitted a stopper, D, preferably of rubber, and substantially conical in form, as shown. Within the stopper D is a space, d, which is of about the same size as theshoulder or ledge c, and communicating with said space is an opening, f, smaller than the shoulder or ledge, so that the stopper has to be stretched when placedupon the lower end of the rod, thus insuring its retention thereon. A disk or washer, E, is mounted on the rod 0, and bears upon the upper side of the stopper I).

F represents a spiral spring,which is located on the rod 0, and which bears against the under side of the closed end of the frame at one end and against the upper side of the disk or washer at its other end. The force of said spring should be sufficient to hold the stopper tightly in place, and yet allow it to be raised when there is an excess of gas in the bottle, and to force the stopper to its seat after the excess of gas has been released.

It will be obvious that by the construction before described all danger of bottles, casks, barrels, jars, or other vessels bursting by reason of the gas therein is prevented.

In the modification shown in Fig. 3 a flat spring is employed. In this case the spring is secured to a frame at one end and bears against the upper side of the stopper at its other end.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Abottle-stopper comprising, essentially, a frame having an opening, a spring-actuated rod sliding therein, a stopper on the lower end of the rod, and a swiveled finger-bar on the ICO upper end of the rod, said bar being adapted adapted to be turned at right angles to the to be turned at right angles to the frame, as set forth.

2. The c0mbinati0n,with a bottle, of a frame having lugs to engage a shoulder on the bottle, a rod sliding in an opening of the frame, a stopper on the lower end of the rod, a swiveled finger-bar on the upper end of the rod,

frame and stopper, as set forth.
