SPECIFICATION formingpart of Letters Patent No. 715,974, dated December 16, 1902.

Application tiled March 10, 1902. Serial No. 97,545. (No model.)

ployed for automatically closing the main check-valve of the bottle when the bottle is turned to a position other than that in which its contents can be poured out.

The object of my invention is 'to provide an improved construction of such a bottle which effectually frustrates attempts to rell it andV yet permits a free discharge of its contents.

In the accompanying drawings, consisting of tw o sheets, Figure l is a sectional elevation of the upper portion of'a bottle embodying my invention, the bottle being in its normal upright position and the plane of its sectional portion being in line l 1, Fig. 7. Fig. 2 is a similar View, the plane of the sectional portion being in line 2 2, Fig. 6. Fig. 3 is a sectional elevation of the bottle, showing the same inverted for pouring out its contents. Fig. 4 is a similar view illustrating the action and position of the balls and the main checkvalve when it is attempted to refill the bottle. Fig. 5 is a horizontal section in line 5 5, Fig. l, looking upward. Fig. 6 is a similar section in line 6 7 looking upward. Fig. 7 is ahorizontal section in line 6 7 looking downward. Fig. 8 is a sectional perspective view of the upper portion of the bottle. Fig. 9 is an inverted perspective view of the channeled plug or stopper.

Like letters of reference refer to like parts in the several figures.

The neck A is provided at a suitable distance below its mouth and at different sides thereof with enlargements B, forming independent pockets or chambers which extend laterally beyond the neck. These pockets are closed on all sides, except their inner sides, which latter open into the cavity of the neck. These pockets may be molded in one piece with the portions of the neck above and below the same, and their top and bottom are horizontal, or substantially so, as shown in the drawings. O indicates an upwardly opening main check-valve, preferably of glass, applied to the section of the neck below the pockets B andhaving a shoulder c, by which it rests normally upon a valve seat or shoulder c at the top of said lower section, so .that the valve is free to open or close by gravity, according to the position of the bottle. This valve preferably has guide-wings c2, which extend into the lower neck-section, and is provided with a conical or upwardly-tapering head c3, which extends above the bottom of the pockets B. In each of these pockets is located a rolling weight D, consisting, preferably, of a glass ball. These balls ,rest upon the bottom of their pockets in the upright position of the bottle, as shown in Figs. 1 and 2, and upon the top of the pockets when the bottle is inverted into a vertical position, or nearly so, as seen in Fig. 3, for discharging its contents. In the latter position the main check-valve C is allowed to fall away from its seat by gravity and under the weight of the bottle contents, the unseated valve being supported upon the opposing sides of the several balls. The depth of the ball-pockets is sufficiently greater than the diameter of the balls to allow the valve to open fully, and the pockets are at the same time so short that when the balls bear against the outer walls of the pockets they do not allow the unseated valve to drop through the space between them. The balls thus form a guide for confining the valve in its proper position when open.

A channeled plug or stopper E of any suitable construction is permanently secured in the neck of the bottle above the ball-pockets B. This stopper is preferably of glass and seated upon stop-shoulders f, formed at the lower end of the upper neck-section by the inner angles or corners of the ball-pockets, which' stop-corners prevent the stopper from being driven inwardly out of place.

The stopper is provided in its surface with IOO a transverse or annular' groove g, the open side of which is covered by the surrounding wall of the bottle-neck. The stopper is also provided at one side with a longitudinal groove or delivery-passage g', which extends upwardly from the annular groove g to the top of the stopper, while with the opposite side of the annular groove a second longitudinal passage g2 communicates, which extends upwardly from the lower end ot' the stopper to a point above the annular groove g and terminates in a descending or return bend g3, which joins the upper side of the annular groove, as shown in Figs. l, 3, and 4. By this construction the discharged liquid iiows through the internal longitudinal passages g"Z g3 of the stopper, thence through the annular passage g, and finally through the external longitudinal groove g'. At the end of the return-bend 93a valve-scat 7L is formed, to which is applied an auxiliary check-valve 7L', preferably of spherical form, as shown. This auxiliary valve is loosely confined in a radial pocket or recess 7L, formed in the annular groove g. The lower end of the stopper is substantially flush with the top of the several ball-pockets B, as shown, so that the balls can roll freely from the pockets over the lower end of the stopper when the bottle is tilted or inverted and so that the space between the bottom of the stopper and the i11- clined upper side of the main check-valve C gradually narrows toward the common center of the ball-pockets.

The peculiar arrangement of the delivery passages or channels of the stopper baflies any fraudulent attempt to unseat either of the check-valves of the bottle by passing a piece of wire orother implement through the channel g.

ln order to pour liquid from the bottle, the same is inverted to a vertical or nearly vertical position, as shown in Fig. 3, in which position the balls D rest upon the top of the pockets B, allowing the main check-valve C to drop from its seat and permitting the liquid to escape around the same and through the channels of the stopper E. The liquid in escaping opens the auxiliary check-valve 7L. Upon righting the bottle the main checkvalve C again descends upon its seat and the balls D return to their formersupports formed by the bottom of the pockets B.

Should it be attempted to refill the bottle by submerging it in a tilted position, the ball which happens to be at the upper side of the neck rolls from its pocket over the inner end of the stopper Ev and by exerting its weight against the beveled head of the main checkvalve forces the valve against its seat and holds it there, as seen in Fig. 4, thus checking the entrance of liquid into the body of the bottle. This wedgiug and closing action of the valve takes place regardless of which side of the neck is at the top, because at least one of the balls will always be in a position in which it tends to gravitate against the conical head of the main check-valve, while the arrangement of each ball in an independent or individual pocket prevents the several balls from rolling together at the lower side of the neck and failing to close the valve.

If it should be attempted to refill the bottle in an inverted vertical position by exhausting the air therefrom or otherwise, any incoming liquid entering the annular groove g of the stopper E will force the auxiliary checkvalve h against its seat, as shown in Fig. 3, and thus be intercepted before reaching the open main valve. The ball-pockets are arranged practically equidistant around the neck of the bottle, and three pockets are sufficient, but a greater number may be employed, if desired.

The combination of a bottle or like vessel having a valve-seat in its neck and provided adjacent to said seat with independent pockets or chambers the bottoms of which extend outwardly beyond the neck and form supports on the outer side of said valve-seat, a check-valve applied to said seat and having a beveled head which rises above the bottoms of the pockets, and rolling valve closing weights located in said pockets, respectively, and arranged to rest upon the bottom thereof in the upright position of the bottle and to bear against the beveled head of said valve when the bottle is tilted, substantially as set forth.
