CHARLES MARCHAND, VOF NEW YORK, N. Y.

BOTTLE-STOPPER.

SPECIFICATION forming part ofV Letters Patent No. 686,315, dated November 12, 1901.

Application tiled April 19, 1901.

To aZZ whom, it may concern:

Be it known that I, CHARLES MARCHAND, a citizen of the United States, residing at New York city, in the county of New York and State of New York,have invented certain new and useful Improvements in Bottle-Stoppers, of which the following is a specification, reference being had therein to the accompanying drawings.

Thisinvention relates to that class of bottle-Stoppers which are provided with a valve to partially arrest the liow of gas released from a liquid contained in a bottle closed by said stopper.

The objects of my invention are to provide asimple and inexpensive stopper with a valve integral with its body and adapted to close automatically a short radial slit or slits made in the inner end of said body, being an improvement upon Patent No. 656,698, granted to me August 28, 1900, said improvement consisting mainlyin narrow strips of paraflined paper or cloth retained in said slot to cover the inner surface of the lips of the valve and prevent them from sticking immovably to each other after having been subjected for a few weeks to the oxidizing action of the liquid in the bottles, said liquid being generallyperoxid of hydrogen, (H2O2,) the sprin gy lips constituting a valve to resist the passage of a fluid under any desired pressure through the slit or slits, but also to permit its passage under a selected pressure, and the relief of the pressure, and thereby preventing the explosion of the bottle or the expulsion of the stopper. I attain these objects by the construction illustrated in the accompanying drawings, in which-n Figure 1 is a vertical section of the elastic stopper with a central plug therein,which constitutes also a cap for the stopper proper, the parts being made slightly conicalto fit Within the neck of suitably-formed bottles. Fig. 2 is a vertical section of the elastic stopper. Fig. 3 is a vertical section of a stopper constructed in accordance with my invention and retained within the neck of a bottle. Fig. 4 is a bottom view of the stopper, showing the paraftined strip of paper projecting from said slit in the bottom. Fig. 5 is a side View of the stopper. Fig. 6 represents7 in 'a large scale, a strip of parafflned paper adapt- Serial No. 56.589. (No model.)

In the center of the stopper there is a vertical cavity or passage 5, which is extended to about one-eighth of aninch of the bottom 6 to obtain an elastic Wall 7 having said thickness. Vertically through said wall there are one or more radial slits 8, (threeradial slits being preferred,) which are normally closed bythe resilience of its walls bearing forcibly against each other. As this stopper is intended to be used mainly to close bottles containing peroxid of hydrogen (H2O2) in water and as said compound gas rapidly oxidizes many substances and even india-rubber and causes the lips of the slits to stick to each other additional means must be used to prevent their adhesion. These means consist ot' one or more narrow strips 13 of paraftined paper or other antisticking material, each one of which is preferably folded transversely, as shown in Fig. 6, and its bent portion pushed into and through the slit, where it is retained by the resilience of the lips of said slit. The lower end of the stopper is preferably in the form of a truncated cone, and said portion is coated with a mixture of wax and paraffin 14 to protect the india-rubber of the stopper against the oxidizing action of the gas H2O2.

The valved stopper above described can be used by itself to close the neck of a bottle and automatically relieve the pressure therein, in which case the cavity or passage 5 may be made very narrow; but I prefer to employ with the elastic stopper a central plug 9, preferably of wood. Said plug is provided with a broad head 10, well adapted to rest upon the head 3 ofthe stopper and to provide a bearing for the binding-Wire 11. The plug 9 fits within the cavity 5, but not closely enough to prevent the passage of gas between said parts when the plug is in its normal condition. To prevent the head 10 of the plug from closing the passage between its bottom and the top of the head 3 of the stopper, there are on top of said head 3 a series of projections 12,

IOO

2. A bottle-stopper consisting of an elastic body having a head extended horizontally beyond its periphery, and having also a central cavity, the bottom Wall of said cavity integral with said body having radial slits therethrough, and'antisticking material retained in said slits substantially as described.

In testimony whereof I affix my signature in presence of tWo Witnesses.

CHARLES MARCHAND.
