INTERNAL BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent N0.320,098, dated June 16, 1885.

(N0 model.)

To aZZ whom it may concern.-

Be it known that I, JAMES TERRY, a citizen of the United States, and a resident of Hartford, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Removable Internal Bottle-Stoppers, of which the following is a specification.

In the accompanying drawings, Figure 1 is a sectional view of my bottle-stopper, partly in elevation. Fig. 2 is a plan view of the packing-disk and its hub. Figs. 3 and 4 are like views of the same, of slightly modified forms; and Fig. 5 is a sectional view, partly in elevation, of my stopper, showing a modified construction of the packing-disk and its hub.

A designates the wire loop of the stopper, having the pressure-head B at its lower end. This wire is straight for some distance at its lower end and rises in a central position from said head, as shown, The other end of the wire is disconnected from the head B. Upon the straight portion of the wire A is the packing-disk at, having a central hub on its upper side, upon the end of which hub is the flange b.

In placing the stopper into the bottle, the free end of the stop-wire A will press against the upper end of the hub and push the packing-disk a through the neck of the bottle.

In order to remove the stopper, it is only necessary to insert a proper tool into the mouth of the bottle and grasp the hub by the flange b. Then pull the stopper out of the bottle. In doing so the packing-disk and its hub first slide upward on the straight part of the wire A, after which the pressure-head B is so far removed from the packing-disk a that the latter may bend downward into a sort of funnel shape as it strikes the neck of the bottle, and thereby reduce its diameter sufficiently to let it out of the bottle.

So far as one feature of my invention is concerned, the packing-disk, its hub, and the extractor-flange b may be made partly of metal and partly of rubber, as shown in Figs. 1, 2, 3, and 4; or it may be made of rubber througlr out, as shown in Fig. 5. In the former construction the metal hub is long enough to form three flanges on itthe flange I), before described, and the flanges a (Z for embracing the upper and lower sides of the packingdisk a for a short distance from its central hole, as shown. In other words, the hub has two annular grooves formed in it, one to receive the packing, and the other to receive the points or hooks of the extractor. These two grooves or three flanges necessarily make so long a hub that when formed of metal with a straight hole of the proper size it could not be slipped over the wire loop after said loop is formed. In order to enable it to be thus slipped upon the wire loop A, I enlarge the central hole at one end. This may be done by enlarging it upon all sides, as shown in Figs. 1 and 2; or by a notch,f, upon one side, as shown in Fig. 3; or by aslit, 9, extending through one end of the hub, as shown in' Fig. 4.

It is desirable that the under surface of the packing-disk a and the upper face of the pressure-head 13 shall come in close contact with each other, and to this end I recess the upper side of the head to a depth sufficient to receive the lower flange, d, as shown in Fig. 1.

WVhen the packing-disk a, its hub, and the extractor-flange are all made of one piece of rubber,the free end of the stopper-wire A may be bent laterally, as at h, Fig. 5, the rubber being sufficiently elastic to admit of the packingdisk and integral hub being slipped over said bent end h and around the loop into the position shown. In either case the hub and eX- tractor-flange are practically integral with the packing-disk, and the whole are adapted to slide together on the stopper-wire as if in one piece.

My bottle-stopper always holds the packing-disk centrally with reference to the pressure-head, and also centrally with reference to the wire loop, whereby it is always properly presented to the neck of the bottle upon the inside, either for extracting the stopper or in seating the stopper for closing the bottle.

My stopper cannot be removed by meddlers or others without proper appliances for entering the neck of the bottle and lifting the packing-disk, thereby insuring a return of the stoppers with the bottles when the latter are returned to the bottlers.

I claim as my invention 1. In a removable internal bottle-stopper, the packingdisk a, having a projecting hub and extractor-flange, 1), upon its outer side, all 3. In a removable internal bottle-stopper, made practically integral and adapted toslide the combination of the wire-loop having a together upon the stopper-wire, substantially free end and the packing-disk having a metal as described, and for the purpose specified. hub with its central hole enlarged at one end,
