BOTTLE-STOPPER AND VENT COMBINED.

SPECIFICATION forming part of Letters Patent No. 523,967, dated August 7, 1894. y

' Application tiled May 16, 1894.` Serial 110.511.438. (No model.)

To all whom it may concern:

Be it known that I', MARTIN L. BERGMAN, a citizen of the United States, residing at Spokane, in the county of Spokane and State of -ferent length than the liquid conducting tube to permit a steady and uninterrupted flow of said liquid when the bottle is held at a proper angle. I attain these objects by the construction illustrated in the accompanying drawings, in which-- Figure 1 is a perspective View of a bottle stopper provided with av central liquid vdischarging tube and two vent tubes on the sides thereof constructed in accordance with my invention. Fig. 2 is a central vertical section of the same with the addition of the cork stopper. Fig. 3 is a perspective view of a modification of the same in which the vent tube is placed in the center and the liquid discharging tube around it. Fig. 4 is a central vertical section of the stopper shown in Fi 3.

In Figs. l and 2 of said drawings A represents the outer tube provided with a collar A2 near its top, and around said tube is placed a yielding cork sleeve C, the collar A2 resting on its upper end. Said tube A has therein a tube B of smaller diameter, that has a portion of its upper end secured to the tube A with a drop of solder b, while its lower end is secured to an extension a2 projecting from the lower end of said tube A, so as to provide two vent passages b2.

Fittingv loosely within the tube Bis placed a liquid discharging tube D'that carries on its upper there is placed a ball valve f to normally close the upper end of the tube D, while the metal bottom of the cage normally rests upon end a cage D2, and within saidcage Y the top of the tube A and closes it. To prevent any liquid from accidentally escaping from a bottle provided with said stopper, while-it is shipped and perhapsl turned upside down; the upper end of the tubeAis extended above the collar A?, and upon said extension' is placed a cap E that is secured thereto either by means of screw-threads in the lower end of said cap or by fitting tightly upon said extension. When the liquid is to be pouredout of the bottle the cap E isy removed and the bottle is held at a suitable inclination to cause the inner tube D to slide outwardly from the tube B until arrested by the collar d on its inner end coming in contact with the inner lend of said tube D, at the same time the ball valve is displaced from its seat, so that while the liquid is owing out an equal amount of air enters therein after passing over the edge of the tube B and through the `vent passages b2.

In the stopper shown in Figs. 3 and 4 the louter tube Fis intended to be used for the discharge of' the liquid and the central tube G which is longer than the tube F is intended as a vent for the passage of the air into the neckof a bottle in which said stopper may be located. Said tube G carries on one end a cage and a ball valve f therein, while the opposite end carries a collar d to limit its motion within thetube F by its coming in contact with the contracted lower end f2 of said tube F, but the tube G is free to move within said contracted portion. The liquid from the bottle isfadmitted within the tube F'through two openings f3 in the side thereof under the cork C placed on said tube. l

Having now fully described my invention, I claims.

l. In a valved bottle stopper the combination of a central tube having a collar on its lower end, a cage in itsupper end and a ball valve within said cage, with an outer tube surrounding the central tube andY having the -valve cage ot the central tube resting on its upper end and perforations leading into the lower portion'of said outer tube substantially as and for the purpose described.

2. In a valved. bottle stopper the combination of a central tube having a collar on its tube, substantially as and for the purpose delower end a cage in its upper end and a. ball scribed. valve within said cage, with an outer tube sur- In testimony whereof I affix my signature in rounding the central tube and having the presence of two Witnesses.

5 valve cage of the central tube resting on its MARTIN L. BERGM AN. upper end and perforations leading into the Witnesses: i

lower portion of said outer tube the outer W. J. C. WAKEFIELD, tube being of different length from the inner L. AMMANN.
