SCREW-STOPPER FOR BOTTLES.

SPECIFICATION forming part of Letters Patent No. 380,782, dated April 10, 1888.

Application filed December 21, 1887.

To all whom it may concern:

Be it known that we, HENRY BARRETT and JOHN JAMES VARLEY, subjects of the Queen of Great Britain, residing at London,England, have invented new and useful Improvements in or applicable to Screw-Stoppers for Bottles Containing Aerated or Gaseous Liquids, of which the following is a specification.

This invention relates to an improved con struction of valve screw-stopper, whereby bottles closed with such stoppers can be filled or charged with aerated or gaseousliquid in a better or more convenient manner than hitherto.

Until now in almost all screw-stoppers having valves through which bottles can be filled after the stopper is placed in the neck the valves have had to depend upon springs (for the most part metal springs) or upon the internal pressure ofgas within the bottle for hold ing or keeping the valve up to its seat.

According to our invention we make use of the elastic property of the material from which the valve is made-videlicet, india rubber for closing the valve by constructing the stopper and valve in the manner hereinafter more particularly described, and shown in the accompanying drawings, in which- Figures 1, 2, and 3 are respectively an elevation and vertical sections of one of my improved stoppers; Figs. 4, 5, 6, similar views of the same, except that a slotted opening, is made in the bottom of the stopper and extend ing up to the hole d,- Figs. 7, 8, 9, similar views in which the rubber valve is a ball instead of a plug; Figs. 10 and 11, an elevation and ver tical section, in which the lower end of the stopper is cut away. Figs. 12 and 13 show the valve-hole in the main body of thestopper,and Fig. 14. is a section showing the manner of opening the passages by compressing the valve by a rod.

The invention may be carried out in several ways, some of which are illustrated in the accompanying sheet of drawings. In one modification (represented in side elevation and vertical sections at Figs. 1, 2, and 3, respectively,) we take a screw-stopper, a, of the kind now used with bottles having a quick coarse female screw-thread in the neck, into which the stopper fits, ajoint being made in the cone at the mouth of the bottle by the elastic ring I).

The

Serial No. 258.597. (No model.)

stopper is made of any suitable material; but we form it with a hole, 0, running down the center and out at the point or lower end of the stopper. A hole or passage, (1, is also made running at right angles with the central hole, 0, and in this transverse hole d we place our india-rubber valve 6, which may be formed of a short length of cord of circular or other shape in cross-section, according to the shape of the transverse hole or passage 12. The diameter of the cord should be somewhat greater than that of the passage d, so that the rubber cord will have to becompressed to place it in the passage. When this cord is in its place, it will close up the end of the central hole, a, running through the stopper, and the-elastic nature of the india rubber cord will keep it pressed tightly against the end of the said central hole, which forms its seat, and so make a tight joint.

A hole or holes, f, is or are made in the end of the stopper at the side thereof, the said hole or holes passing to the hole (I, in which the valve e is placed, and which hole or holes f is or are uncovered to allow the liquid to pass into the bottle when the valve is pressed inward either by the pressure of the liquid or otherwise-as, for instance, by a pressing-rod.

The stopper shown in elevation and vertical sections at Figs. 4, 5, and 6, respectively, is the same as that shown at Figs. 1, 2, and 3, with the exception that a slotted opening, 9, is made in the bottom of the stopper to the hole (I.

In place of the above-named valve 6, we sometimes cmploy a rubber ball, e, to form the valve, as shown in the stopper represented in elevation and verticalscctions at Figs. 7, 8, and 9, respectively.

Figs. 10 and 11 represent an elevation and a vertical section of a stopper similar to that shown in Figs. 1, 2, and 3, except that the lower end of the stopper is cut away at each side, as sh own at h h,whereby, the valve e having less bearing-surface, the holes f are not required.

In Figs. 12 and 13 we show an elevation and section of a stopper, in which the valve 6 is placed in a hole, d, made through the middle part of the stopper. In this case, as the rubber valve does not extend from one end of the hole (I to the other, the holes f f are not required.

In order to fill a bottle closed with one of ourimproved stoppers, the stopper is screwed tightly into the neck of the bottle and the bottle filled by a suitable filling-machine through the central hole, 0, the pressure being sufficient to press down the valve e, so as to allow the liquid to pass through small holes-such as f into the bottle. WVhen the bottle has been sufficiently filled, a pressing rod or needlesuch as iis employed to press down the india-rubber forming the valve 0, as shown in Fig. 14, and the excess of air or gas is allowed to escape, or, as it is techanically termed, snifted through the holesff, and upon the presser or needlei being removed the valve 6 will close the openings 0 andf. In the case of the stopper shown in Figs. 10, 11, 12, and 13 the bottle is filled and snifted through the hole d.

Having now particularly described and ascertained the nature of our said invention and in what manner the same is to be performed, we declare that What we claim is 1. A screw-stopper having within intersecting passages made through its body a stationary valve of elastic material and of larger di- 25 ameter than its valve-seat, and serving by its own resilience to close at the same time both said passages.

2. Ascrew'stopper forbottles havingtherein an axial'and a transverse bore communicating 0 with each other, and an elastic valve serving by its own elasticity to close such communication.

3. A screw-stopper with a vertical passage,

0, having a gradual downward taper, a transverse passage intersecting the same near its 5 bottom, and a tight-fitting elastic valve lodged in the space where these passages intersect.
