Specification of Letters Patent,

' Patented Maren 27, 19L6.

Application filed il'anuary 24, 1905. Serial No. 242,557.

A To @ZZ whom, it may concern:

' ter of the prior United States Letters Patent granted to me, No. 741,965, dated Octobei 20, 1903'.

The invention has forits object to reduce considerably the' initial cost of Siphon-bottles, to admit of one tapbeing used for any number of bottles, and to allow lthe stopper to be readily removed, so that the Siphonbottle may be as easily washed as any ordinary bottle. l

The improved stopper according to my invention is also constructed in such a way that it may be adapted for use with existing siphon-heads or taps.

In the accompanying drawings, Figure 1 illustrates, partly in section, a tap constructed according to my invention. Fig. 2 is a i' sec-tional elevation of my improved stopper as applied to a Siphon-bottle, said stopper being here shown projecting above the neck of the' bottle. Fig. 3 is a sectional elevation of a slightly-modified form of stopper adapt- .'ed to be screwed entirely in theneck of the bottle,.as shown. Fig. 4 illustrates a varied form of tap for use with a siphon vessel for nre-extinguishing purposes. Figs. 5 and 6 'l are respectively side and plan views, and Fig.

7 a side view of details to be hereinafter referred to.

The invention consists of a screw-stopper a, made of porcelain or the like and ada ted to screw-into the neck of the Siphon-bott e b, as shown in Fig. 2 or Fig. 3. Centrallyl of the stop er a is situated the hollow stem c of a valve and at its upper portion said stem c is externally threaded and has screwedthereon a piece of porcelain e, having` a central bore and provided at its base with a recess, into which is fitted a cork washerf.

Round the stem cin a hole in the stopper c is placed a spiral spring g, retained in position by a screw-nut h, while/for insuring a tight' joint between stopper aand neck of siphonl bottle b a sealing-ring t', of rubberV or other material, is inserted, as shown in Fig. l.

A rubber washer j is placed on the seat of the valve d and is arranged to be retained tightly against such seating by a hollow externally-threaded piece of porcelain 7, to which latter is suitably securedthe Siphon-tube m. The hollow stem c of the valve d is provided sage of the liquid in the Siphon-bottle.

For operating the valve d I provide, ac-

l cording to the best construction, a tap o,

comprising a hollowplug portion p, having a cork liner g, a spout s, and a top piece r, said plug portion and spout s being connected by a passage u.

In the modification shown by Fig. 3 the neck of the bottle is extended in length and the stopper a is located entirely therein. In this construction the rubber washer j is recessed in the valve d, as shown by Fig. 7, and

the piece 7c is placed between rings and y,

which rings y, together with the piece c, are

firmly secured between the stopper a and the shoulder o in the neck.,

In both constructions the action is as follows: Upon placing the plug portion p of the tap o within the upper hollowpart of the stopper al and imparting pressure onto the with a number of holes nfor the outward pastop piece 1' the tap o willpress down the porcelain piece e and valve against the force of the spring g, and thus bring the holes n of d below the washer j in the example shownby Fig. 2 or below the yvalve-seating in the example shown by Fig.

3, whereby V the liquid has free access to the hollow valve-stem c, and owing to the pressure ofthe gas contained in the liquid the latter will -b'e forced up through the said hollow valve-stem c, passage u of the tap o, and out of the spout s of the latter.

As will be understood, the holes n in the valve-stem c are normally closed by the force ofthe spring g, keeping the valve d close up against the washer j, as in Fig. 2. or the valve d, with its inserted washer y', Fig. 3, close upy against the valve-seating, thus making it impossible for any liquid to pass into the stem c until the valve is opened by the application of external force.

For fire-extinguishing purposes a tap as illustrated by Fig. 4 is employed, with the exception that a vertical spout s and fingerholds t are provided. This tap is similar in all respects to that shown in Fig. 1, and in connected thereto, l

use with a vessel having like mechanism in the neck thereof as described the liquid will be forced out of the spout on the plug portion being Apressed onto the porcelain piece e.

AS hereinbefore stated, the Siphon-stopper described may be used with an ordinary tap consisting of a metal head with lever and rod or similar device for operating the valve by screwing or otherwise connecting such an ordinary tap-head to the stopper, as at Fig. 2, or to the neck of the bottle, as at Fig. 3.

Having now described my invention, what I claim as new, and desire to secure Iby Letters Patent, is-

l. A stopper for siphonbottles comprising a screw-stopper made of porcelain, in one piece, and having a chamber provided at the top thereof and a tapped hole formed in the bottom thereof, said chamber and tapped hole being in connection by a central passage in which and within the limits of said stopper and in combination therewith is located a valve having a hollow stem provided with a number of holes at its lower end anda collar at its upper end, a spring for closing said valve and a thimble-piece screwed in the hollow of said stopper and carrying the Siphontube substantially as described.

2. A stopper for Siphon-bottles comprising, in combination a screw-stopper made of porcelain in one piece, said stopper havin(r a chamber formed in the top thereof, an a tapped hole formed in the bottom thereof, a valve having a hollow stem provided with a number of holes at its lower end and a collar at its upper end, and a spring for closing Said valve, said valve, stem, spring and collar being located centrally of and within the limits of said stopper, a thiinble-piece screwed in the bottom of said stopper and carrying the siphon tube, washers located between said thimble-piece and stopper, and stopper and bottle, substantially as described.

3. In combination with a Siphon-bottle, an outlet-valve, a stopper having a chamber at the top thereof, a tap having in combination a hollow plug adapted to lit into said chamber when opening the outlet-valve of the bottle, a discharge-spout and a top piece,

said discharge-spout and plug being in conimunication, and said plug having a resilient lining to fit around the top of the said outletvalve when said plug is placed in said chamber, substantially as described.

In testimony whereof I a'l'lix my signature in presence of two witnesses.
