JAMES S. PORTER, OF BUFFALO, NEW YORK.

BOTTLE-STOPPER.

Specification of Letters Patent.

Patented May 16, 1911.

Application led August 18, 1910. Serial No. 577,761.

To all whom it' may concern:

Be it known that I, JAMES S. PORTER, a citizen of the United States, residing at Buifalo, in the county of Erie and State of New York, have invented new and useful Improvements in Bottle-Stoppers, of `which a goods and thereby prevent injury both to the manufacturer whose bott-les may be used improperly and also protect customers against deception.

In the accompanying drawings: Figure l is a vertical section of the upper or neck part of a bottle equipped with my improved stopper, the parts being in the position which they occupy when the bottle is in a normal upright position. Fig. 2 is a similar view showing the posit-ion of the parts when the bottle is in an inclined or pouring position. Figs. 3 and 4c are horizontal sections in lines 3 8 and 1-4, Fig. l. Figs. 5 and 6 are detached perspective views of the parts of the stopper.

Similar letters of reference indicate corresponding parts throughout the several views.

A represents'the bottle and a the neck thereof. The outer part of the bore of the neck is cylindrical or of uniform diameter, as shown at c, while its inner part is enlarged in diameter, as shown at CZ, and is constructed to form an outwardly-facing an-I nular concave valve seat c at the inner end of the enlargement d and an inwardly facing annular shoulder f at the outer end of said enlargement.

G represents the valve or closure of the stopper and g the stem thereof. This valve is preferably of substantially cylindrical form and has its face L arranged on the underside thereof and constructed of concave form corresponding to the valve seat of the neck.

The Valve is movable freely lengthwise in the enlargement d of the neck, so as to engage or disengage its face from the valve seat and either close or open communication between the interior of the bottle and the The diameter of the valve is less than that of the bore of the enlargement d,

so as to permit the liquid contents of the bottle to flow outwardly past the valve when the latter is moved away from the seat upon tilting the bottle. The flat outer or rear side of the valve is prevented from engaging the outer shoulder f of the enlargement when the valve moves outwardly by means of a pair of stop lugs h1, 71.1 arranged diametrically opposite each other on the rear side of the valve and adapted to engage with the outer shoulder f, thereby permitting free escape of the liquid from the bottle when the same is tilted, which would not be possible if the rear side of the valve were permitted to engage the shoulder f. The valve is pref- `erably constructed of cork so that it is buoyant, but if desired the same may be constructed of other suitable material.

The stem of the valve may be constructed of glass or other suitable material and is secured at its front or inner end to the outer side of the valve while its outer end slides lengthwise in the contracted outer part of the bore of the neck,ffor which purpose the stem is made of suiiiciently smaller diameter than the valve and made of Vsuch length that its outer end is still within the contracted outer part of the neck when the valve is closed.

The stem of the valve lits the outer part of the bore of the neck sufficiently close to longitudinal grooves or channels y' through which the liquid passes. A deflection or band is preferably formed spirally in each of these grooves, as shown at c in Figs. 1 and 5, whereby the inner and outer parts of each groove are arranged out of line with each other. Vhen pushing a wire through a groove j it results in bending or turning the wire to one side as its front end engages the shoulder formed by the deflection k, thereby defeating any attempt to interfere with the working of the stopper by this means.

Inasmuch as it is very diiiicult, if not impossible, to grasp the valve stem at its outer end by a tool, the possibility of relling the bottle by resorting to this means of holding the valve in an abnormal position is reduced to a minimum.

The valve and stem may be connected in various ways but preferably by providing the inner end of the stem with an inwardly-project-ing spur L which is pushed through a central opening Z formed in the valve between its stop lugs 71,1, h1. The inner end of this spur is pointed and provided with a head or enlargement m which forms an outwardly-facing shoulder n on said stem at the outer side of said head. As the spur is pushed through the opening in the cork valve, the fibers of the latter are distended by the pointed inner end of the head but these fibers again contract at the outer end of this head adjacent to t-he shoulder n, whereby the on its seat, as shown in F ig. l, and prevents the introduction of any liquid into the bottle. Upon tilting the bottle, as shown in Fig. 2, the valve moves away from its seat and its stop lugs lil engage the shoulder f, thereby permitting the liquid to escape. Any attempt to introduce liquid into the bottle while in this last mentioned position will be frustrated by reason of the fact that the cork valve will rise against the valve seat and prevent admission of liquid to the interior of the bottle.

After the bottle has been originally filled with liquid, the stopper is pushed downwardly in the neck so that the valve remains within the contracted outer part oi the neck, whereby the valve is contracted and serves asa cork or stopper to close the bottle while the same is being shipped or stored, thereby dispensing with a separate cork or closure for this purpose. Preparatory to pouring liquid'from the bottle it is only necessary to push the stopper inwardly sufficiently to carry the valve into the enlarged inner part of the neck and when this is done the valve expands so that its lugs h1 will engage the shoulder f upon moving the stopper outwardly and thus prevent withdrawal of the stopper.

I claim as my invention:

The combination of a bottle having the outer part of the bore of its neck contracted and the inner part of said bore enlarged and provided with a valve seat at the inner end of said enlargement, and a stopper having an enlarged valve arranged in said enlarge ment of the neck and adapted to engage the face on its front side with said valve seatand provided with a central opening and with stop lugs on its outer side, and a contracted valve stem arranged in the contracted part of said neck and providedwith a spur arranged in said opening and also provided with notches on its periphery with which said lugs engage.

l/Vitness my hand this 16th day of August, 1910.

JAMES S. PORTER.
