. To all whom it may concern.-

Be it known that I, JACOB F. THEUHER, a citizen of the United States, and a resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Apparatus for Charging Liquids with Carbonic-Acid Gas, of which'the following is a specification.

My invention consists in a new and improved carbonic acid charger to be used prinoipally for the impregnation of beerand other malt liquors in connection with the method andapparatus referred tojin United-Stains Letters Patent No. 478,176, dated July 5, 1892, granted to John B. Stobaeus and Frederick (J. Wackenhuth. I

The nature of my said invention will be best understood when described in con nection with the accompanying drawings, in which Figure 1 represents a frontelevation of the charger and connections. Fig. 2 is a plan wow. 2, of the upper part of the charger and of the regulator. Fig. 4 is a sectional view of the regulating valveon an enlarged scale.

Sim lar lettors'of reference indicate corresponding parts throughout the several views of the drawings.

Referring now to said, figures the letter A designates the charging vessel, which is made of sheet copper lined with tin.

The top end of "the, vessel A is provided with a brass flange Sriveted 'andsoldercd to the shell, and to this flange the brass head or cover B is removahly secured by wing-nutsb. Flhe lower end of the vessel A is closed by a brass head 0 riveted and soldered to the shell and resting upon a base N. The head (I has a central hole into which is screwed a nipple c with elbow e. v The cover 8 has a central hole into which is screwed a pipe f (Fig. 3) projecting some distance down into the charging vessel and cnrryingat its lower end a fora-ruinous disk I). To the upper end of the pipe f above the head 13 is screwed an elbow (I connected with 8lb0$2 c at the lower head C in the manner.

shown, with an interposed three-way cock E and gate-valve h, and with gate valve (1 on the horizontal lower branch.

Fig. 3 is a section on the line 9: m Fig.

the hose 0 is coupled. To the lower head 0' the end of the hose i'is eou ieii, so as to establish free communication from the top of the charging vessel A tothe top of the vessel V, and also from tho bottom-of vessel A to the bottom of vessel when valves n and m are open.

The regulating vessel Y, is supported upon a vertically adjustable scale bcam L, the lower end of the vessel V being provided witha fork a having a steel bearing resting upon a steel knifeedge on the right hand end of the scale lever L, while then-pipe projecting from the upper endds'gnided in an arm 8 projecting from avertical rod 1. This rod! is attached to a block K and to a block S-and projects above the latter. The block K has a brass nut inserted through which passes the thread ed rod it which turns in fixed bearings at the top and bottom ofthe charging vessel, its lowercnd projecting through the lower bearin; and being provided with a hand wheel M.

The block 9 slides freely o n the threaded rod It.

The projecting: arm of the block K carries a knifedge bearing for the scale lover L.

Upon the left hand end of the scale lover is placed an adjustable weight W. 7

The blocks ii and S are. prevented from turning by nfixed rod 'l passingthrough them and secured at the top and bottom of the clmrgin r; vessel. .liyturning the hand wheel )l, the block It; is moved up or down, carry ing uith it the scale. lever-l. supporting the vessel also the rod 6 with its projecting-arm s which guides the top of the vessel \',nllow ing a limited independent vertical motion of the latter.

To a lateral opening in tho liangc ll of the charging vessel-A is attached the carbonic EGO acid supply. piece anu regulating valve ll shown in Fig. 4 in section on a larger scale. The carbonic acidsupply regulated by a suitable valve enters this piece H through flexible tubej and opening K, the supply being further regulated by the conical valve L operated by lever L To the shaft of this lever Z is attached on the outside an arm q the end of which is pivoted to a rod :1:. An-arm y is adjustably secured to one of the rodsu of the regulating vessel V and pivoted in ablock w adjustably secured on the rod :13. By an increase in the contedts of the vessel V the same is lowered, the arm y pulls down the rod 11 and arm q thereby-opening the regulating valve '0. On a de rease of the contents of vessel V, it is raised to close the valve '0.

I will now proceed to describe the operation of the apparatus, assuming that beer is to be impregnated with carbonic acid. The water supply hose is attached to the hose coupling i, the coclc E and valve F being closed, and water is admitted into the chargg ing vessel A by opening the valve G and the air-cock 2'. As the water rises Within the vessel the air is expelled through cock z and when the water commences to flow out through the cock 2, the supply is shut off and cock .2 is closed. The water supplyghose is now disconnected from. the couplin'gi and the gas supply turned on, the Weight. W being so placed that the gas valve remains open. The valves E and F are opened so that any water in the pipe may flow out, displaces the water in the cylinder and'connections and flows out through coupling 2, and when the vessel A and connections are filled with gas the'valve G is closed, the beer supply hose is connected at coupling g and the hose for carrying ofi the charged beer at coupling h. 'vT B valves E and F are then :iproperly set.v The vessel V is placed at the desired height by turning the hand whelal and the'weight W adjusted 'so' as to obtain the proper degree of impregnation. When. 'ever through anincreased resistance in the discharge of beer, the level of beer in the vesvsel A rises, the increased weight in the regulating vessel causes the same to descend and increase the opening of the carbonic acid valve n. The increased flow of carbonic acid increases the pressure in the charging vessel A so as to overcome the increased resistance to-dis charge. A fall of .the level of the beer 'inthe charging vessel A and regulating vessel V has the opposite effect.

By. the means'shown'and described, in connection with themethod and apparatus described in. Patent No. 478,176, above mentioned, I am enabled to obtain a uniform impregnation of the beer.

My invention is not restricted to the means shown and described for supporting and adjusting the regulating vessel, or to the arrangement of the various connections, since these may be varied, as well as other details.

If desired the hose coupling h for the dis- The gas gradually charge of the beer may be omitted and the ouplingi used for the purposes of an inlet and'outlet for water, and an outlet for the 7c impregnated beer.

I do not in this applicatibn broadiy'cla m the combination in a carbonic acid charger of a charging vessel with means for automatically operating the valve 01''- valves for the ad- 35 mission of liquid or gas by the variation of the liquid level in the charging vessel, such a nation being claimed in my prior app ication filed January 24, 1893, Serial No.
