OTTO RITTER, OF ST. LOUIS, MISSOURI, ASSIGNOR OF Ola E-H'ALF TO MEYER t HOFMAN, OFA SAME PLACE;

v WORT AND YEAST AERATOR FOR BEER-VATS.

SPECIFICATION forming part of Letters Patent No. 466,310, dated December 29, 1891.

Application filed August 4, 1891. Serial No. l101,658. (No model.)

To all whomk it may concern:

city'of St. Louis, in the State of Missouri, have invented a-certain new and useful Improvement in Wort and Yeast Aerators for Beel'- AVats, of which the following is a full, clear, and exact description, reference being had to vthe accompanying drawings, forming part of this specification. Y

This apparatus is constructed and arranged consists in features of novelty hereinafter fully described, and pointed out in the claims. Figure I isa detailview of the aerator and shows the coupling for the air-hose, the airilter, the bulb-casing of which lter forms a handle or hold for the operator, by which he directs the instrument. It also shows the i`nception filtered air-chamber, the supply airtube, and the compound aerating-bulb;` and Fig. II is a vertical section of a brewers fermenting-va't and shows the yeast and wort aerator in active operation therein.

Referring to the drawings, 1 represents a brewers vat resti-ng on its sleepers 2, and 3 is the Wort with its quota of yeast deposited i-n said vat and'iu the process of fermentation. 4 represents the usual circlettelnperator v that is suspended in the wort within the vat,

and 'are the refrigerator-pipes that conduct a current of cold air to, through, and from said temperator.

The construction and operation of the aerating apparatus are as follows: 6 represents a pneumatic hose, which may be of rubber or any other suitable material, and which gets its supply of air from any suitable pneumatic force-pump worked by power or hand. The said-hose lits over the corrugated periphery7 of the metal coupling-tube joint 8, to which it is tightly held by the binding wire orfcord 9, and the terminal iiauge 10 of said tubejoint lits and is thus held within the iange 11 of the screw-coupler 12, whose inner screw 13 engages on the rear peripheral screw 14 of the coupling-tube plug 15, whose forward peripheral screw 16 engages in the internal screw 17 of the initial dange 18 of the tubulous bulb 19, which incloses the air-filter 20. The said filter-bulb is filled with sterilized cotton 21 or other suitable airY filtrant as an antiseptic to cleanse the air that passes f through it of all noxious ingredients. resents a perforate disk that lits against the advance screw-threaded end 23 of said tubulous lter-bulb, on which peripheral screw is Y seated the internal screw 24 of the rear iange 22 rep- 55 25 of the secondary tubulous bulb 26, which in- 6o closes the pure-air chamber 27, which is supplied with cleansed air through the perforations in said disk 22 direct from the said airfilter.

engages on the peripheral screw 30 of the joint-pipe 31, which pipe has a screw-tight attachment ma the elbow-joint pipe 32 with the pendent pipe 33, which pendent pipe has a The internal screw 2S of the forward attachment fiange 29 of said secondary bulb 6 5 y screw-tight connection 34 with the head 35 of 75o the initial tubular plug 36.

37 represents the secondary aerating tubular plug, within the internal screw 38 of which the peripheral screw 39 of the initial plug engages to effect a screw-tight-joint connection of said two plugs. 40 represents the expanf sion air-chamber within said initial plug, into which the forced air is driven from the pendent pipe 33, and from which chamber the air is concentratively driven through the con- 8o verging tube 4l, the blow-pipe 42, and concave outlet 43 into and through the initial yeast and wort mixing and aerating concentrating-tube 44 within said secondary aerat- The rapid forced draft thus pro- 8 5 in g-plug 37. vided produces a powerful suctionvof lthe wort and yeast in the vat through the open ports 45 in the upper part of said aerating-l tube, and together the wort, yeast, and rapid air-current are forcibly concentrated in'said 9o converging tube 44, thus intimately mixing said wort and yeast and aerating the same by said concentrative process, and then violently ejecting the aeriferous compound into the expansive bulb 46, from which it is violently ejected through the perforations 47 of its rose end 4S. The said action forcibly drives the aerated compound against the inner surface of the rose-terminalof said bulb,

and thus still more intimately and forcibly rco conducing to the aeration and effervescence of the fermenting compound, both within said bulb, and as it is forcibly ejected into the vat through the perforations or open ports 47 the whole contents of the vat `aresoon'aerated 105 and in a high state of effervescence.` The upl l -ru n per end of said bulb-terminal section 46 is provided with an internal screw 49, that is screw-seated on the peripheral screw 50 of the secondary plug to hold said bulb in its attachment to said plug.

The operation of the device has necessarily been mostly portrayed in this description, but may be more clearly understood by the following brief capitulation and addenda. The tubulous filter-bulb 19 having been filled with sterilized-that is, purified-cotton and the various parts of the apparatus described before securely screw-seated together and attached to the pneumatic hose,which is worked by a force-pump the operator grasps the said tubulous filter-bulb, which also constitutes a handle, and inserts the aerating-bulb and the pipe-stem 33, that carries it in the wort and yeast in the beervat. As the airis forced rapidly through the apparatus, being cleansed of all noxious impurities as it passes thronghthe before-described pneumatic filter, it whirls (with the first break in its current since it left the filter) into the expansion-chamber 40, from which it darts through the converging contractile tube 41 'via the blow-pipe 42 and concave expansion-outlet 43 into the aerating concentrating-tube 44, generating a strong suction-draft through the open ports 45, drawing a rapid current of the wort and yeast in the vat through said ports into and through said aerating concentrating-tube, aerating it on its way and expelling it With great force and thrashing it against the perforate rose expansionbulb 46 and through the perforations 47 into the main body of wort and yeast in the vat, which it rapidly aerates and ferments. The operator meantime moves the aeratingbulb around: so that it visits in its journey all parts of the vat, so as to make the aeration and fermentation of the contents much more rapid than by the old process, repeated trials ofthe device having proved a saving of two days in the operation, with a more lively and effective fermentation.
