APPARATUS FOR DRAWING OFF LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 688,586, dated December 10, 1901. Application led August Z6, 1901. Serial No. 73,250. (No model.)

To all whom may con/067%:

Beit known that I, ALFRED BRAKE, a subject of the King of Great Britain and Ireland, residing at Clapham, London, England, have invented Improvements in Apparatus for Drawing Off Liquids, of which the following is a specification.

This invention consists of improvements in that kind of apparatus for drawing off liquids in which a vessel, commonly called the intermediate vessel, is normally in communication with the liquid-storing vessel, so that it will stand charged with liquid ready to be drawn 0E; and it has special reference to apparatus for drawing off lager-beer'and other like liquids highly charged with gas under pressure and hereinafter referred to as beer, wherein theintermediate vessel, which serves as a frothing and settling chamber, is normally in open communication with the liquidsupply pipeor vessel, is provided with a normally closed liquid-discharge pipe or passage leading from its lower end, and is adapted to have its upper part, which is normally disconnected from the external atmosphere, placed 'in communication with such atmosphere, when required, so as to allow of gas under pressure therein being released, when desired, without closing the liquid-inlet or opening the liquid-outlet. Apparatus of this kind is described in the specification of my United States Patent No. 673,532.

My presentinvention has for its object to enable lager-beer and other frothy liquids (hereinafter referred to as beer) charged with gas under pressure to be drawn ed either with very little froth or with a creamy head of froth of any desireddepth. j

The invention consists, for this purpose, in an improved construction ot' draw-olf apparatus wherein the liquid-inlet of the intermediate vessel or frothing chamberis in constant communication with the liquid-supply pipe or vessel and is made of smaller cross-sectional ranged as to placethe top of the intermediate vessel only in temporary communication with the externalv atmospherewhen operating the apparatus for the purpose of drawing off its contents or a portion thereof, so that upon A operating the apparatus for the purpose just mentioned the gas-outlet will be first opened to release the gas-pressure and then closed, and the beer-outlet will be opened and beer allowed to run out of the intermediate vessel faster than fresh beer will4 run into it, and Without any admission of air to such vessel, with the result that beer can be drawn off in advantageous manner and with very little froth. y

The invention also consists in providing in connection with the said intermediate vessel means whereby any desired quantity offrothy beer can be drawn oiii' into a glass or other receptacle, either after or before the main quantityof beer has been drawn off,with very little froth, so as to produce the desired creamy head of froth.

The invention also consists in various other novel features of construction and in certain combinations and arrangements of parts, all as hereinafter more fully described, and specifically pointed out in the claims.

In the accompanying illustrative drawings, Figure l shows in vertical section one construction of draw-off apparatus constructed according to this invention, and whereby beer can bedrawn off with very little froth. 2, 3, i, and 5 are sections onthe line A A of Fig. l, showing the plug of a cock forming part of that apparatus in four different positions. Fig. 6 is a vertical section showing drawingot`f apparatus like that illustrated in Fig. l, but adapted to admitof a small quantity of frothy beer being drawn od direct from the beer-supply pipe. Fig. 7 is a cross-section on the line B B of Fig. 6. Figs. 8 and 9 are cross-sections on the line C C of Fig. 6, showing the plug of the draw-off cock in two different positions. Fig. lOris a similar View to Figs. l and 6, showinga modified construction for enabling a small quantity of frothy beer to be drawn od.

In the arrangement shown in Figs. l to 5, inclusive, the intermediate vessel a, which Figs.

may be of pewter, glass, or other suitable ma- IOO .smaller than the liquid-outlet.

, below the normal level of the liquid in the vessel andterminates near totheinnersurface thereof. At its lower end the said vessel a is provided with a beer-outlet pipe (Zand also with a gas-outlet pipe e, the top of Which terminates within and near to the top of the said vessel, and the lower end of which terminates in a passage e', arranged near to a beer-outlet passage d', communicating with the pipe d. The beer and gas outlet passages d and e are controlled by a cock or faucet comprising a plugf and a case g, which in the example forms part of a tubular device h, in which the said beer and gas passages d and e' are formed and which is provided with a socket ,vin which the lower end of the intermediate Vessel ais secured in a fluid-tight manner by a divided screw-ring 7c and a packing-ring lm. The pipes d and e are secured in the bottom of the socket t', so as t-o be in communication with the passages d and e', respectively. The passages d' ande terminate in ports d2 and e2 within the case g, and the plugf is formed with ports f and f2. These ports d2, c2, f', andf2 are so relatively arranged, as shown, that normally (see Figs. 1 and 2) the beer and gas outlet passages d and c' are both closed and that upon turning the plug fin the direction of thearrow l by the handle t the gasoutlet passage e will be first opened through the port f', Fig. 3, and then closed, Fig. ft, after which the beer-outlet passage d will be opened through the port f2, Fig', and upon turning the plug in the opposite direction backinto its original position the beer-outlet passage d will be first closed and then the gasoutlet passage e will be again momentarily y opened and closed. The intermediate vessel a may, as shown,conveniently resemble a bottle in shape and be held in an inverted. and inclined position within a box n, adapted to contain ice, the neck of the bottle-shaped vessel being carried by the tubular device h, which extends through a hole in the lower portion of the said box, in which it is secured by a screw-ring 0V or other suitable means and a packing-ring o.

By the construction described the intermediate vessela will normally stand nearly filled with beer charged with carbon dioxid under pressure, and above it, within the upper part-A and upon the liquid-outlet being afterward opened while the gas-exit opening is closed the beer will be discharged by gravity, aided by the gas-pressure still existing in the vessel and the intlowing beer, the beer iowing out into a receptacle in a smooth steady stream with the production of very little froth. During the drawing olf a fresh quantity of beer will enter the vessel, but at a slower rate than the issuing beer on account of the cross-sectional area of the inlet being less than that of the outlet, this iniiow continuing after the liquid-outlet `has been closed and until the level of the liquid rises to the normal height and the gas-pressure in the vessel balauces the pressure under which the beer is supplied. To obtain the best results,

a short interval should elapse between sucv cessive drawing-off operations to allow time for froth producedin the vessel during the iniiow of a fresh quantity of beer to settle. For this purpose, where it is desired to draw off lager or like beer frequently, it is convenient to use several vessels, arranged side by side,and to draw off .beer from each of them in succession.

In some'cases, instead of drawing off beer of the lkind referred to into tumblers or other receptacles, so that there shall be very little froth Qn the surface of the drawn-ofi:` beer, as hereinbefore described, it is desired that the surface of the beer shall be covered with a creamy head of froth of, say, about twelve millimeters in depth. To enable this result to be attained, the drawing-off apparatus is constructed in such a way that after any desired quantity of the beer has been drawn off with very little froth from the intermediate vessel the beer-outlet can be placed in direct communication .with the rbeer-supply pipe or vessel or with the intermediate vessel with out releasing the gas-pressure from such vessel, so that the necessary small quantity of frothy beer can be drawn off to produce the desired effect. Usually the movable handle or equivalent (hereinafter called the handle employed for effecting the drawing off of beer from the intermediate vessel will be employed for opening the outlet for frothy beer. For this purpose the handle may be so arranged that when moved in one direction it will effect the release of gas under pressure from the top of the intermediate vessel which is in communication with the beer-supply Ypipe or vessel, as before, and will eect the opening of the beer-outlet from the said vessel, and upon being moved into another position it will open the passage for the supply of frothy beer.

As will be obvious, draw-off apparatus of the kind herein referred to can be constructed in various forms to give the above-mentioned result. purpose in Figs. 6 to 9, inclusive, the intermediate vessel a iscarried by va tubular device h, formed, as before, with beer and gas IOO IIO

outlet passages d and e', that are respectively in communication with the beer and .gas pipes d and e and are controlled by the plug f of a cock or faucet constructed and operating as hereinbefore described with reference to the arrangement shown in Fig. 1. The tubular device h is, however, formed with a third passage t, that is connected by a suitable by-pass pipe u direct to the liquidsupply pipe c and termi-natos in a port fu in the valve-case g, and the plug f is formed with a third port f3, so arranged in relation to the other two ports f' and f2 that when the plug is turned backward by its handle Z beyond its normal position (shown in Fig. 8) and into the position shown in Fig. 9 it will open the third porto and the secondary pipe t and allow frothy beer to be drawn off, for the purpose set forth. Z is a spring by which the handle Z will when released be automatically returned to its normal position, Fig..

8, in which each of the ports d2, e2, and o is closed.

As the beer standing in the intermediate vessel would issue therefrom in a frothy condition if the excess of gas-pressure in the top of the vessel were not released previous to the drawing off, it will be obvious that a small portion of such frothy beer may be drawn off for producing the desired amount of head on the drawn-off beer having very little head. For this purpose the plug f may, as shown in Fig. 10, be formed, in addition to the ports f and f2, with a third port f3, so arranged that after beer has been drawn off with little or no head and the plug has been returned to its normal position and the vessel a allowed to become recharged with a fresh quantity of frothy beer, as hereinbefore described, a small quantity of such beer can be drawn off by turning the plug backward to a small extent beyond its normal position, so as to again open the liquid-outlet d', but this time through the port f3 and without releasing the excess of gas-pressure from the top of the vessel., so that frothy beer will then be drawn olf. With the arrangements shown in Figs. 6 to l0, inclusive, the desired quantity of frothy beer can, if desired, be first drawn off by moving the handle backward and then the desired quantity of beer with very little froth can be drawn off by moving the handle forward. Also with the arrangements shown in Figs. 6 to 1U, inclusive, the cock can be used for opening the intermediate vessel a for drawing off beer without opening the gas-exit port e2 at all when for any reason the pressure of the gas in the said vessel falls so low that it need not be reduced before opening the beer-exit port d2.

It will be evident that va rions changes could be made in the details of construction of my apparatus without departing from the spirit and scope of the invention so long as the relative arrangements of parts shown in the drawings or the mode of operation described in the specification is preserved.
