APPARATUS FOR CARBONATING LIQUIDS.

SPEGIFIGATION formingpart of Letters Patent No. 660,740, dated October so, 1900.

Application filed October 6, 1899. berial No. 732,799. (No model.

To aZZ whom it may concern:

Be it known that I, ALFRED WALL, brewer, a subject of the Queen of Great Britain and Ireland, and a resident of Lezayre road, Ramsey, Isle of Man, England, have invented a certain new and useful Apparatus for Carbonat-ing Liquids, of which the following is a specification.

The object of my invention is to provide an improved apparatus for carbonating liquids.

The process of carbonating liquids by carbonic-acid gas has been done heretofore before bottling, and by means of my invention this process can be accomplished after bottling.

Referring to the drawings which form a part of this specification, Figure 1 represents an elevation of the apparatus, shown partly in section. Fig. 2 is an enlarged section of an improved self-acting stopper forming part of this invention, Fig. 3 being an outside view of the same; and Fig. 4 is an enlarged section of the tube and valve for inserting in the stopper when carbonatingin the manner hereinafter described.

In the several views, A is the bottle the liquid in which is required to be carbonated; B, the improved self-acting stopper, which is fitted to the neck 0 of the bottle.

D is the tube inserted in the end of the stopper B, having a rubber-cork-connecting cone E and loose brass washer F. The said small tube has a miter valve end G and passes through the screwed valve-seating H and is kept gas-tight by the stuffing-box I, formed by the nut J. This screwed valve-seating H is screwed to the inlet-piece K by means of the nut L. The aforesaid small tube D is hollow for a greater part of its length, as shown at M, and is provided with asmall hole N, leading from this hollow portion to the outer surface of the tube. This small hole forms the automatic inlet, to be hereinafter described. The coil-spring 0 serves to keep the tube D pressed upward, with the miter end resting against the seating H. The gas is admitted through the inlet P from the pressure-reservoir or gas-supply into the chamber of the inlet-piece K, but cannot escape further on account of the small tube D being close against the seating H by the action of the coil-spring O.

The process of carbonating takes place in the following manner: The bottle already filled with the liquid is stoppered by the improved stopper aforesaid. This stopper is made in such a way, as shown by the detail section in Fig. 2, that the gas .or any other material to be admitted into the bottle can be so admitted through said stopper, but can not escape back again. To do this, I form a hole B through the stopper lengthwise and nearly along its length, and at the inner termination of said hole I form another at right angles, extending from the center to the side, as shown at B This hole is covered by an india-rubber tube or band B which envelope the outer surface of said stopper. The bot tle and stopper are placed in an inverted position in a suitable frame or stand R, the upper portion of which has a stem Q, terminating in a flange S at its lower end, the upper end sliding in a socket T, containing a spiral spring Uto keep said stem bearing down upon the base of the bottle. The sliding socket has an eye at its upper end and in its turn slides up and down in the frame and is con trolled by the lever V. When the bottle is in position, the lever V is raised and puts a pressure on the bottle against the upward pressure of the spring 0 and so depresses the small tube D, forcing it downward till the side hole N is exposed to the chamber of the inlet-piece K, and the gas rushes through the smalltube D and the improved stopper B into the bottle. When the liquid has been sufficiently carbonated, the handle of the'leverV is pulled down, thereby releasing the pressure on the bottle, and the india-rubber ring B on the stopper B prevents any escape of gas from the bottle, and at the same time the spring 0 forces the miter end of the small tube D against its seating and shuts off communication from the gas-inlet P through the small hole N, and this lower valve is thus automatically closed and the bottle can be removed.

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

In a fluid-carbonating apparatus the com bination of a frame, a reciprocating resilient bottle-carrying stem carried by the frame, a conical tubular cork for the bottle having a lateral inlet and provided with a flexible band surrounding the sides of said cork and lateral held and filled by inserting the tubeand cone inlet, a, spring-retracted reciprocating tube within the bottle-neck. 1o exteriorly coned at its outer end and hav- In Witness whereof I have hereunto set my ing an elastic cone-washer adjacent thereto hand in presence of two witnesses. adapted to enter said tubular cork, a valve ALFRED WALL.
