lMPRdVEMENT IN APPARATUS FOR DRAWING EF FERVE SCENT LIQUIDS.

Specification forming part of Letters Patent No. 144,809, dated November 18, 1873; Reissue No. 7,113, dated May 16, 1876 Reissue No. 8,200, dated April 23, 1878; application filed March 6, 1878.

To all whom it may concern:

Be it known that I, THOMAS WARKER, of New York, in the State of New York, haveinvented a new and Improved Apparatus for Drawing Effervescent Liquids, of which thefollowingis a specification, reference beinghad to the accompanying drawing, which represents a side view of my apparatus, partially in section.

This invention consists in a novel process of drawing efiervescentliquids by first conducting the same into a chamber in which free or surplusgas can be let off from said liquid, and in then drawing the liquid from said chamber with-. out subjecting said liquid to any pressure, the liquid flowing out through the discharge-spout of the chamber by its own gravity, my said process enabling the liquid thus drawn to preserve its effervescent character, inasmuch as the rapid escape of the gas from the liquid (which is indicated by foaming or frothing of the same while being withdrawn) is effectually prevented.

The invention further comprises, in an apparatus for drawing effervescent liquids, a pressure-relievin g chamber, provided with an inlet passage and valve and an outlet passage and valve, in combination with the vessel or fountain from which the liquid is drawn, whereby an apparatus is provided for carrying my said process into efi'ect.

The'invention further comprises certain novel combinations of parts, whereby a very complete, and, in its details, conveniently-operated and effective apparatus is provided for carrying the principle of my said invention into effect.

A designates the pressure-relievin g chamber,

which is connected by a pipe, B, with a vessel or reservoir, 0, that contains an eifervescent liquidsuch, for instance, as champagne, soda- In this pipe B is a stop-cock, D, which controls the communication between the vessel G and the relieving-chamber A, and a valve, E, is provided to let off any pressure or free gas that may exist in the relievin g-ch amber. This valve E may be arranged at any convenient place between the vessel 0 and the relieving-chamber A,"and it may be connected with the stop-cock D, so that it opens when said stop-cock is closed, and vice versa. On the bottom end of the relieving-chamber A a discharge-spout, F,

is secured, which can be opened or closed by a stop-cock or valve, Gr, and this valve may be so. arranged that it can be opened by hand, or that it opens and closes automatically, according to the position given to the relieving-cham ber. The pipe B is provided with a coupling or other suitable device, so that the same can be conveniently secured to the mouth of a champagne-bottle, or to any other vessel containing an efiervescent liquid.

If a portion of this liquid is to be drawn into a tumbler or other receiver, the valves E and G are closed and the stop-cock D is opened, whereby the relieving-chamber Ais filled to any desired point. To effect this purpose, the vessel 0 must either be turned up, or the pipe B must be so arranged that it extends down into said vessel, close to its bottom, by which latter arrangement the pressure on the top of the liquid in the vessel G will force said liquid into the chamber A. After the relieving-chamber has been filled to the desired point, the stopcock D is closed; and, by opening the valve E, the free gas in the top of the chamber A will escape, and the liquid in said chamber is relieved from all pressure; and, by opening the valve G, such liquid discharges by its inherent gravity, without producing any foaming or frothing, as the discharge of the free gas leaves the liquid without agitation, thereby preventing the same from losing its life or effervescence.

If the effervescent liquid is discharged from the vessel 0 under the pressure due to the free gas collected in said vessel above the liquid, the force of the discharge will produce frothin g and foaming, whereby the gas, indicated by the efi'ervescing of the liquid, will more readily escape by the force of this violent agitation during the discharge, and the liquid in the tumbler has lost its life.

By my arrangement of this intermediate chamber A, the free gas collected in the top of said chamberA is first allowed to escape when the liquid discharges itself by its inherent gravity, retaining a large portion of the gas with which it has been charged, and thus retaining its life or effervescence in the tumbler.

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

1. The'herein-described process of drawing effervescent liquids, by first causing them to pass into a pressure-relieving chamber, Where the free or surplus gas is let off from the liquid, and then drawing the said liquid Without pressure and by its own gravity from said chamber, substantially as herein set forth.

2. In an apparatus for drawing efiervescent liquids, the pressure-relieving chamber A, provided with an inlet passage and valve, and an outlet passage and valve, in combination with the vessel or fountain from which said liquid is supplied, all substantially as and for the purpose herein set forth.

3. The herein-described combination of a pressure relieving chamber, constructed to permit the escape of surplus gas, and to permit the outflow of the liquid by gravity alone, and a vessel or fountain containing effervescent liquid, the said parts bcing'provided with controlling-valves, all substantially as and for the purpose herein set forth.

4. The described combination of the press ure-relieving chamber A, having a dischargespout, F, the gas-escape valve E, and the pipe 13, having a stop-valve, D, and adapted to a -.vessel containing effervescent liquid, in the manner and for the purpose specified.
