BOTTLE-STOPPER.

SPECIFICATION forming part of Letters: Patent No. 400,436, dated April 2, 1889.

Application tiled December 25, 1888. Serial No. 294,613. (No model.) y

To all whom it may concern:

Be it known that I, WILLIAM BELL CHAM- BERS, a citizen of the United States, residing at Newark, in the county of Licking and State of Ohio, have invented new and 'useful Improvements in Bottle-Stoppers, of which the following is a specification.

My invention relates to improvements in bottlestoppers; and it consists in acertain novel construction and combination of devices, fully described hereinafter in connection with the accompanying drawings, and specifically pointed out in the appended claims. l

-In the drawings, Figure 1 is a perspective view of the stopper embodying my invention applied in the operative position to the neck o f a bottle.` Fig. 2 is a vertical central sectional view of the same.l Fig. 3 is a detail view of the ring detached from 'the bottle.

Referring by letter to the drawings, A designates the nee-k of an ordinary bottle, around which, just below the shoulder a thereon, is arranged the ring B, the said ring being provided at diametrically-opposite points with the laterally-extending trunnions t b. This ring is preferably formed as shown in the drawings-namely, of the two semicircular sections B B', of wire, the ends of which are bent outward and arranged close together to form the trunnions b. The yoke C extends over the mouth of. the bottle, and its arms c c (which pass down on opposite sides of the neck of the bottle) are provided at their lower ends with bearings c c in whichA fit the trunnions b b, whereby the yoke is pivoted to the neck of the bottle. A milled cap, D, fits over the mouth of the bottle, (its depending flange d iitting closely around the sides of the same,) and a vertical threaded stud, E, which is permanently secured to the center of the cap, engages a central threaded aperture, C', in the yoke.

A ground-glass disk, E', is fitted in the cap D and bears on the mouth of the bottle when the cap is screwed down in place to form an air-tight joint, and a rubber cushion, F, is arranged between the glass disk and the upper side of the cap, which is compressed when the cap is screwed down, thereby insuring an even pressure on the glass disk. A metallic disk, G, is interposed between the cushions and the glass disk to preventfriction between the same when the cap is screwed down, and a collar, g, is secured in the cap below the glass disk to hold the latter in position.

I am aware that swinging yokes have heretofore been used in connection with bottles and in combination with Stoppers provided with threaded studs; but it will be observed that in the improved device the yoke is revovluble on the neck of the bottle, owing to the peculiar connection thereto, and therefore after the cap has been screwed down until the glass disk is in contact with the mouth Vof the bottle the yoke is revolved, thereby clamping the cap down more .iirmly than is possible by simply rotating the cap, owing to the friction between the ground glass and the bottle; also, in removing the stopper it is impossible to turn the cap until it has been loosened by first revolving the yoke.

Having thus described the invention, I elaiml. In a bottle-stopper, the combination of the revoluble yoke C, connected to a ring on the neck of the bottle, the cap iitting over the mouth of the bottle and provided with a Ver-v tical threaded stud engaging a central tapped aperture in the yoke, and the ground-glass disk E, secured loosely in the cap and adapted to bear on the mouth of the bottle, whereby the yoke maybe rotated to raise or lowerthe cap without rotating the cap or the disk and the disk may be pressed against and removed from the mouth of the jar, substantially as specified.

2. In a stopper, the combination, with a revoluble yoke connected to the neck of the bottle, of the cap provided with a threaded stud engaging a threaded aperture in the yoke, the glass disk arranged in the cap and bearing on the mouth of the bottle, the compressible cushion interposed between the said disk and the upper side of the cap, and the collar arranged below the disk to hold it in place, substantially as specified.

3. In a stopper, the combination, withl a revoluble yoke connected to the neck 4of a bottle, of the cap provided with a vertical IOC threaded stuud engaging a threaded aperture In testimon)7 that I claim the foregoing as in the yoke, the glass disk arranged in the myown I have hereto affixed my signature in cap and bearing on the mouth of the bottle, presence of two Witnesses.
