L. ROORBAOH, OF PHILADELPHIA,

BOTTLE-STOP PER.

SPECIFICATION forming part of Letters Application filed May 9,1887.

To all whom it may concern:

Be it known that we, GEORGE W. TUCKER and WILLIAM L. ROORBAOH, both citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Bottle-Stoppers, of which the following is a specification.

'lheobject of our invention is to so construct a bottle-stopper for gaseous liquids that while the bottle can be filled when upright and the stopper closed by the pressure of the gases thereon said stopper can be readily adjusted to and will be self-retaining in such a position as to permit the escape of the liquid from the bottle, a further object being to permit the forcing of the stopper into the bottle when the latter is to be washed, and the ready returning of the stopper to its former position prior to filling, as fully described hereinafter.

In the accompanying drawings, Figure l is a perspective view of our improved bottle-. stopper. Fig. 2 is a sectional view of the bottle with our improved stopper closing the mouth. Fig. 3 is a view showing the-stopper forced down and retained in this position so as to permit the pouring of the contents from the bottle. Fig. 4 is a view of the stopper in the position to which it is adjusted when the View of the stopper with part of. the same in a different position from that shown in Fig. 1. Fig. 6 is a view showing the mode of forcing the stopper into the bottle. Fig. 7 is a view showing the mode of introducing the stopper inthe first place; and Figs. 8 to 13, inclusive, are views of modified forms of stopper in accordance with our invention.

A is a bottle having a neck, a, and B is the stopper, comprising a flat stem, 11, having near the lower end a sealing-disk, D, and near the upper end a frictional retainer, E. The stem of the stopper we prefer to make of rubber; but any suitable material which will withstand the strain to which it is subjected may be used, thesealing-disk and retainer being preferably of ordinary vulcanized rubber. The stem b has at the lower end a head, b, and in the stem above said head are notches c for the reception of the sealing disk D,which is larger than the head b of the stopper and alsolarger than the mouth a of the bottle.

Patent No. 367,254, dated July 26, 1887.

Serial No. 237,579. (No model.)

In order toperinit the stopper to enter the bottle in the first place, as shown in Fig. 7, we form notches d in the stem b of the stopper, directly above the disk, the latter when it is turned up, as shown in Fig. 7, resting in these notches, so as to prevent the disk from binding in the. neckof the bottle. The disk D is adapted to seat against the inner portion -of the neck of the bottle, as shown in Fig. 2,

the gases maintaining a coustantpressur'e upon the disk from the inside of the bottle, so as to retain said disk in position for sealing the bottle. The upper portion of the stopper B has notches h in each side, so as to form a central piv0t-pin,f, and an elongated.head,f, beyond the same. Between this head and the body of the stem we insertaflexible retaining-plate, E, which is narrow, as shown in Fig. 1, but of such length as to rest upon the mouth of the bottle and prevent the stopper from dropping into the same when the bottle is empty, as shown in Fig. 4.

-When the bottle is to be filled with the liquid, the stopper is in the position shown in Fig. 7, the sealing-disk D being at some distance below its seat, so that any filler of the ordinary construction may be used for filling the bottle. As soon as the bottle is filled, however, the stopper assumes the position shown in Fig. 2, the disk D being forced up splashing and uneven tlow,which is an obj ection to this class of stoppers as usually made, and it also allows the bottle to be closed when onlya portion of the liquid has been removed, the closing being effected by the simple lifting of the stopper until its sealing-disk is again seated.

NVhen it is required to clean the bottle, the

plate E is turned to the position shown inFig. 5'-that is to say, at right angles to the elongated head f'so that when-the stopper is forced into llllllllllllltltlllltltltltlhtllt t wi T the bottle the flexible ends of the plate are at liberty to bend at the sides of the head, so that the stopper can be readily forced into the bottle,as shown in Fig. 6; and when the bottle has been washed the stopper can be restored to its former position by means ota hook, at, (shown by dotted lines in Fig. 6,) said hook being adapted to catch under the plate E and withdraw the stopper from the interiorofthe bottle.

Vhen it is required to remove the stopper from the bottle entirely, which is only necessary when a worn-out disk, D, has to be replaced, we cut the disk by any suitable tool, after which the stopper can be readily removed; or, if desired, the head I) of the stop per may have a ring, I), formed on it, as shown in Fig. 13,in which case the disk Dneed not be cut, the stopper being reversed in the bottle and removed by a hook, it, engaging with the ringb'flas shown in the figure mentioned above.

\Ve have shown the stem 01' the stopper in the form of a flat plate; hutsaid stem can be made of wire in skeleton form, as shown in Fig. 8, or in the form ofa tube, as in Fig. 9, or can be made with wings I)" at each side, as in Fig. 10, the forms shown in Figs. 9 and 10 tending to keep the stopper centrally in the neck of the bottle.

In Figs. 11 and 12 we have shown the head 0 f pivoted to the stem portion of the stopper by a pivot-pin, f, the flexible retainer E being stationary on the stem b. This pivoting of the head f effects the same result as the pivoting of the retainer, for when it is desired to drop the stopper into the bottle the head f is turned on its pivot-pin, as shown in Fig. 11., so as to permit the stopper to be forced into the bottle, as shown in Fig. 12. XVe notch the upper portion of the stem 1) at i i in this case, so that the stopper can be readily pulled out of the bottle again to the position shown in Fig. 4.

\Ve claim as our invention- 1. The combination, in a bottle-stopper, of a stem with a sealing-disk at one end and an oblong flexible retainer at the opposite end, 1

with an oblong backing for the retainer, one being movable with reference to the other, sub stantially as and for the purpose specified.

2. The combination, in a bottle-stopper, of the stem provided at one end with a scaling disk and at the opposite end with an elongated head and an elongated flexible retainer, free to turn on the stem, all substantially as set forth.

3. The combination, in a bottle-stopper, of the stem 7), having a sealing-disk atone end and notched at the opposite end to form an elongated head,with an elongated flexible retainer fitted to and free to turn on the notched portion of the stem and having a bearing against the elongated head, all substantially as described.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
