IMPROVEMENT IN APPARATUS FOR DRAWING EFFERVESCENT LIQUIDS.

Specification forming part of Letters Patent No. 144,809, dated November 18, 1873; reissue No. 7,113, dated May 16, 1876 application filed April 12, 1876.

To all whom it may concern:

Be it known that I, THOMAS WARKER, of New York, in the State of New York, have invented a new and Improved Apparatus for Drawing Elfervescent Liquids, of which the following is 'a specification, reference being had to the accompanying drawing, which represents a side view of my apparatus, partially in section.

This invention consists in the arrangement of a pressure-relieving chamber between the vessel or fountain from which the effervescent liquid is to be drawn and the vessel which is to receive the liquid so drawn; and, further, in the arrangement of three valves, one of which controls the communication between the liquid-containing vessel and the pressurerelieving chamber, while the second serves to let ofi the surplus gas from the relievingchamber, and the third serves to draw the liquid from said chamber into a tumbler or other vessel intended to receive the same.

By this arrangement the liquid to be drawn is first led into the pressure-relieving chamber, from which the free or surplus gas can be let off, when the liquid from said relievingchamber can be drawn Without being subject to any pressure, and will flow out at the discharge-spout into the tumbler or other receiving-vessel by its own gravity, whereby the liquid thus drawn preserves its eflervescence, as all frothing or foaming will thereby be prevented.

A designates the pressure-relieving chamber, which is connected by a pipe, B, with a vessel or reservoir, 0, that contains an efi'ervescent liquidsuch, for instance, as champagne, soda-water, or other fluid charged with gas. In this pipe B is astop-cock, D, which controls the communication between the vessel O and the relieving-chamber A, and a valve, E, is provided to let off any pressure or free gas that may exist in the relievingchamber. 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 relievingchamber A a discharge-spout, F, is secured, which can be opened or closed by a stop-cock or valve, G, 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-chamber. 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 effervescent 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-cockD is opened, whereby the relieving-chamber A is 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 0 will force said liquid into the chamber A. After the relievingchamber A has been filled to the desired point, the stop-cock 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 efl'ervescence.

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 frothing and foaming, whereby the gas mixed with the effervescent 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 chamber A 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-v 1. The combination of a vessel or fountain,

0, containing effervescent liquid, and a presslire-relieving eh amber, A, provided with a discharge-spout, F, and having a gas-escape valve, E, connected with its upper end, said chamber A being situated between the vessel 0 and the discharge-spout F, so arranged that the liquid will flow out of the chamber A by its inherent gravity, in the manner and for the purpose substantially as described.

2. The described combination of the pressurea-relieving chamber A, having a dischargespout, F,the gas-escape valve E, and the pipe B, having a stop-valve, D, and adapted to a vessel containing efl'ervescent liquid, in the mannerand for the purpose specified.
