. Specification forming part of Letters Patent No. 48,422, dated lune 527, 1865.

cation, in which- Figure 1 is a side view of the instrument. Fig. 2 is a central vertical section of a bottle closed by means of an inner valve, andshows the application of my instrument, which is represented in red outline.

Similar letters of reference indicate corresponding parts in both of the gures.

The object of this invention is to provide for` the opening of such stoppers as are applied within bottles or other yessels and closed from the inside either by means of a spring or by the pressure of the gas evolved from the liquid contents of the vessel or with which the said contents have been mechanically charged, or by any other means.

The invention consists of a tube or other device ot' suitable size and form to enter the mouth of the bottle or other vessel and press the stopper inward away from its seat without interfering materially with the ingress or egress ot' the'liquid, and one or more attached clasps or other devices to operate against the .exterior ofthe bottle or other vessel in such manner as to serve both as a guide to keep the tube or other internally-acting device in place and as a means of holding it against the pressure by which the stopper isclosed when the opening-instrument is removed from the b ottle or vessel.

The instrument may be made in a variety of forms 5 but it will be sufficient for the illustration ot' my invention to represent by drawings and describe that form which I atpresent consider adapted for the most extensive and general use, and I will now-proceed to describe it with reference to the drawings.

To a metallic cap-`piece, A, of a circular form, is secured, by riveting or otherwise, the elastic caps or clips B B B, which are made either of wire or steel plate. The said cap-piece has acentral opening, to which is attached a tube or hollow boss of any hard, durable, and water-proof material-such as vulcanized india-rubber or gutta-percha-of an external diameter that will just allow it to pass loosely into the neck of the bottle. Through this tube the liquid passes when being poured from the neck of the vessel which contains it, and any leakage which would occur from the liquid passing along the sides of this center piece and out between the mouth of the bottle and the lower surface of the cap A is prevented by a soft-rubber packing-rin g, D, which forms a water-tight joint between the mouth of the bottle and the cap A when the instrument is applied to open the stopper of a bottle, us shown by' the red outline in Fig. 2.

wardly-opening valve,such as is represented in section in Fig. 2, the instrument-the cap being uppermostis forced downward over the neck ofthe'bottle E, the clasps, clips, or springs B B B spring apart until they clear the upper portion of the neck of the bottle, and the portions ofthe springs which are bent toward the center enter the depression s of the bottles neck and hold the valve F open by the hollowA center pushing against the helical spring G', which is fastened to the valve-stem H. The contained liquid can then be poured out, or, if the vessel is empty, the same may be lled.

In order to allow the valve to close, the instrumentis withdrawn and the valveis brought to its seat again by the spring. This bottleopener entirely obviates the necessity of the person opening the bottle holding the valve in that position against the pressure of the gas and the sustaining-spring G so long as he desires the liquid to run from the bottle, for the clasps, clips, or springs not only hold the tube C` or its equivalent against the valve vor stopper, but in case ot' the said tube or Vequivalent not being of a form to lit the neck ot' the position as will not interfere with the llin g or pouring.

In order to open a bottle closed-by an in-v bottle they serve as guides to keep itin such The clasps by which the opener is attached to the bottle may be constructed and applied to operate upon any other portion of the bottlc than the neckas for i nstancc, to hook over the bottom.

The cap-piece may be of a form to t over the exterior of the bottle and serve as the guide to keep the tube G or its equivalent in its place in the neck, in which case a single clasp or hook attached to the neck would serve to hold the instrument on the bottle.

What I claim as new, and desire to secure by Letters Patent, is-

1. An instrument for opening and holding open the inwardlyclosing stopper of a bottle,

consisting of an internally-operating device for JOHN MATTHEWS, JR.
