BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 551,413, dated December 17, 1895. Application filedMarch 2, 1895. Serial No. 540,295. (No model.)

T0 at whom it may concern:

Be it known that I, WILLARD B. STEVENS, a citizen of the United States, and a resident of the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification.

This invention relates to improvements in that class of stoppers that are placed in bottle-necks to prevent the refilling of the bottles.

The object of my invention is to provide a new and improved stopper of that kind which is simplein construction, can readily be placed in a bottle-neck and firmly secured in the same and which thoroughly prevents pourin g liquid into the bottle after the stopper has been inserted.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter.

In the accompanying drawings, forming a part of this specification, and in which like letters of reference indicate like parts in all the views, Figure l is a side view of my improved stopper in the bottle-neck, showing the wooden fastening-ring before the same has been expanded. Figs. 2, 3, and 4 show modified constructions of the stopper in a bot tlencck.

The stopper is constructed with a head A, fitting snugly in the neck 13 of the bottle and having a central aperture a, through which the liquid can be poured out of the bottle. A guard-cup C, made integral with the head and provided with a series of apertures or slots O, extends downward from the under side of said head, as shown.

The bottom annular edge of the head A is rounded or beveled, as shown, and a short distance above said. rounded edge the head is provided with the exterior annular groove D, which when the head is placed in the bottleneck registers with an interior annular groove E in the bottle-neck, the bottom of said groove being rounded or beveled oif, as shown.

A ring 1* of compressed wood is sprung into the groove D in the head A, the thickness of said ring being such that it does not project beyond the periphery of said head, as shown in Fig. 1, so as not to interfere with inserting the head into the bottleneck B.

After the head has been inserted in such a manner that the grooves D and E register, and the liquid contained in the bottle saturates the ring F of compressed wood, the latter swells and expands and fills both grooves D and E, thereby securely holding the stopper in the bottle-neck, as shown in Fi 2.

The bottom of the groove E is rounded oil in the manner shown and described for the purpose of guiding the wooden. ring F when it expands into said groove, for if the bottom of the groove were not rounded cit the ring might be jammed against the inside of the neck and in that case would not pass into the groove.

The head may be provided with a cage G, extending downward from the same and which, with the head, is inserted into the bottle, as shown in Fig. 1, or the head may be constructed without said cage, as shown in the remaining figures. At the bottom of said head a seat for a valve H is formed or said sea-t maybe formed by an annular interior projection I of the bottle-neck. The valve 11 is approximately in the shape of an inverted cone exteriorly rounded off at the wider end, so as to have a ball-bearing on its seat. From the bottom of said valve H a series of radial wings J project,which increase in width from their upper to their lower ends, the weight of said wings being greater than that of the valve, so as to hold the valve on its seat.

Vhen the bottle is tilted to pour out its contents, the valve H is lifted from its seat and the wings J serveto seat the valve when the bottle is righted again. At the same time the wings J do not interfere in the least with the ready flow of the liquid, even when the edges of said wings rest against the bottom of the cage G or the bottom of the annular flange or collar 1 in the bottleneck.

As shown in Fig. 3, the valve Il may have an iiiverted conical part it fitting on the valveseat and. a central upward conical projection h, whiclnwhen valve opens, passes into an inverted conical recess L in the closed bottom of the guard-neck G. \Vhen the bottle is righted again the valve is guided and directed properly upon its seat by said projection 71. and recess L. The projection it also serves for guiding liquid that is poured into the bottle toward the rim or seat part of the valve Having thus described inyinvention, what,

I claim as new, and desire to secure by Letters Patent, is

1. The combination with a bottle having an interior annular groove in its neck directly below the upper end of the same, the bottom of which groove is rounded off, of a stopper fitting in the bottle neck and provided with an exterior annular groove a short distance below its upper end and of a wooden retainin g ring located within the said two grooves.

2. The combination with a bottle of a head held in the neck of the same, which neck has a downwardly projecting guard cup, an upwardly opening valve below said guard cup, which valve is provided with downwardly projecting radial wings, increasing in width from their upper to their lower ends, the upper ends of said wings being permanently fixed directly to the bottom part of the valve, substantially as herein shown and described.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 1st day of March, 1895.
