To all whom it may concern:

Be it known that I, CHARLES EDWARD 3EAVIS, a citizen of Great Britain, residing at Bristol, in the county of Gloucester, England',-,have invented certain new and useful Improvements in Valve-Stoppers, (for which I have obtained patents in Great Britain, No. 12,713, dated July 2, 1895, and No. 14 ,309, dated July 27, 1895, and in Germany, No. 85,099, dated August 18, 1895;) and I -do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new or improved stoppers for use in bottles'or vessels containing liquids and gases under pressure, and

and one particular shape of valve.

has for its object to provide meanswhereby stoppers can be placed in the necks or openings of bottles previous to filling and be antomatically sealed by a valve and washer when the bottle is filled.

My invention consists in making screwstoppers of any usual form and size, with a tubular perforation from the top to the bottom, through which the bottle is filled, a valve fitted in this opening efiectually sealing the stopper after the vessel is filled.

This invention is primarily intended for use in stoppering bottles containing mineral and other waters and beverages under pressure, and the following description and drawings refer exclusively thereto, but it may be used in connection with cylinders or'other vessels containing gases.

In the accompanying sheet of drawings, Figure 1 is a side view of a screw-stopper with the valve inserted ready to be placed in the neck of a bottle. Fig. 2 is a section of the same, showing the interior of the stopper Fig. 3 is a plan of the same. Fig. 4 is another plan of the stopper, with a triangular-shanked valve. Figs. 5, 6, and '7' are respectively elevations of three differently-shaped valves which appear to be most suitable for thepurpose-viz., to admit the liquid readily to the bottle and automatically seal the stopper.

For the sake of clearness all thefigures' are shown considerably enlarged.

A is the upper part of an ordinary screwstopper and 7 Figs. 1 and 2, ready for insertionin stopper, and B the usual rubber washer to make the stopper air-tight, the screw-threaded lower part C fitting into the neck of the bottle. A circular hole I) is made to a suitable depth in the upper part 0;? the stopper. Below this the hole is continued with a reduced diameter E right through the stopper, thus forming a set-elf or seating d, on which the flange or collar of the valve rests.

G is a valve around which a rubber washer II, Fig. 1, is placed. On the upper part of thevalve a flange .1 is formed, by which the valve is supported on the seating (1 ready for operation. The shank I or the part which connects the flange to the lower part, on which the washer is placed, may be of any suitable shape. Three varieties are shown in Figs. 5, G, and 7, the lower part being identical in each case. In Fig. 5, which is the one preferrcd, the shank is made cylindrical and the upper part turned out to form the flange J, with two or more apertures K made in the side of the cylinder to allow the liquid to flow freely into the bottle. Fig. 6 shows the supporting-flange and valve, connected by three wires. In this case if the flange J is a circular disk chases F (see Fig. 4) must be made at'the side of the perforation beyond the seating to permit the liquid to pass the disk. Fig. 7 shows another shape of the shank and fiange--viz., triangular. this is in Fig. 4.

To provide for the more rapid escape of air from the bottle while it is being filled, a small. vertical passage L is made from the base of the-stopper to a horizontal passage M in or near the top, which conveniently terminates in the side of the stopper, as shown in Fig. 2.

The various parts being provided as described, the valve-shank I is inserted through the perforation D E in the stopper, the flange J restingon the seating d. The rubber washer H is sprung or stretched over the lower part of I the valve G to fit tightly (when pressed) against the bottom of the stopper (3. The valve will then be complete, as shown-in the screw-threaded neck of the bottle.

In the manufacture of mineral waters and the like the stoppers fitted with these valves are'inserted in the bottles after washing by Plan of p unskilled labor, and then the bottles are taken to the machines and filled through the perforation in the stopper without any of the delay usually caused by havingto insert the screwstoppers after the bottles are filled, the gas in the liquid pressing the valve r and washer II tightly against the base of the stopper, the flange and upper part of the valve oc-(mpying the position shown by dotted lines in Fig.- 2, the escape of air beingeontrolled by machines having special appliances for snifting.

In opening bottles fitted with this improved valve-stopper if it is desired to allow any superfluous gas to escape before disehargin g the liquid the flange may be slightly pressed, which will eause the valve to drop to its original position, the gas to be liberated, and allow the stopper to be unscrewed and the contents poured out without any waste.

I am aware that stoppers have already been made with openings through them for the purposes of filling and air-exhausting. To the perforated stopper in itself I make no claim; but I What I claim as my invention, and desire to protect by Letters Patent, is as follows:

1. The eombination,wi th a tubular stopper provided with an air-hole I, in the thickness of its side wall; of a shank I slidahle in the said stopper and provided with a longitudinal passage for liquid, and a valve at its lower part below the stopper, said valve operating to close both the passage for liquid and the air-hole when the shank is raised, substantially as set forth.

2. The combination, with a tubular stopper provided with an air-hole in the thickness of its side wall, a seat (Z below its top and a chamher D above the said seat; of a hollow shank I provided with a solid bottom, a lateral waterpassage K, a flange at its top normally resting on the said seat, and a valve at its lower part below the said stopper, said valve operating to seal both the air-hole and the waterpassage through the stopper when the shank is raised, and the said chamber affording protection for the upper part of the shank, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
