JULIUS Z. FORMEL, OF SARATOGA SPRINGS, NEW YORK, ASSIG-NOR TO THE CHAMPION NATURAL CARBONIG ACID GAS COMPANY, OF SAlrlE PLACE.

APPARATUS FOR CARBONATING FERMENTED BEVERAGES.

SPECIFICATION forming part of Letters Patent No. 561,879, dated June 9, 1896.

Application filed August 21, 1895. Serial No. 559,982. (No model.)

To all whom may concern:

Be it known that I, JULIUS Z. FosMEL, a citizen or the United States, residing at Saratoga Springs, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in Apparatus for Carbonating Fermented Beverages, of which the following is a specification.

This invention has reference to an improved apparatus for carbonatiug beer and other fermented beverages, so as to dispense with the so-called hraeusen process and obviate the reintroduction of yeast-cells into said beverages; and the invention consists of an apparatus for charging fermented liquids with carbonic-acid gas, which comprises a receiver for the carbonic-acid gas, a primary mixing-tank connected with the receiver and storage-cask for producing the primary mixing of the liqnid and gas, a carbonating-tank in which the liquid is intimately mixed with carbonic-acid gas by being minutely distributed within the same and brought in contact with the gas, supply-pipes for the gas and liquid, and a floattank connected with the carbonating tank and with the valves of said gas and liquid supply pipes, so as to interrupt or establish automatically the supply ofgas and liquid to the carbonating-tank as the level of the liquid in the same rises and falls, and means for conducting tho carbonated liquid to the shipping- ];eg.

The accompanying drawing represents a side elevation, partly in vertical longitudinal section, of my improved apparatus for carbonating fermented liquids.

In the drawing, A represents the receiver for the carbonic-acid gas under pressure. The receiver A is connected by means of apipe a with a suitable battery of cylinders B, containin g liquefied carbonic acid, the pipe abein g provided with a pressure-reducing valve a, so that the carbonic acid is expanded to the required pressure into the receiver A. The receiver A is provided with another pressurereducing val ve a? and pressure-gage a so that the gas can be supplied at any desired pres sure into the carbonating apparatus. The

gassupply pipe A connects the supply-tank A with a primary hurling-tank U and a carbouatin g-tanl: D. From the gas-supply pipe A extends a valved branch pipe c, having a small discharge-nozzle c into the liquid-supply pipe E, which connects the storage-cask S with the primary mixing-tank O. The upper part of the primary mixing-tank G is connected by a pipe (Z with the carbonating-tanlc D. Valved branch gas-supply pipes a a extend from the main supplypipe A respectively into the primary mixing-tank O and carbonating-tank D ,the nozzles of said branch pipes c and a coming in connection with the liquid-supply pipes E and d in the nature of injectors, the nozzles of said branch pipes c and a being placed in line with the axis of the liquid-supply pipes E and (Z. The liquid is thereby first forced into the primary mixing-tank C and there kept in agitation by the supply of gas by the branch pipe a while the main supply-pipe A supplies the carbon atingtank D directly with gas of the required pressure, so as to permit the starting of the carbonating operation. After this is done the valve near the end of the main su pply-pipe A is closed off.

The carbonating-tank D is made of a closed cylinder, which is provided at its upper part with a perforated annular trough or funnel D, to which the liquid is supplied from the primary mixing-tank O by the pipe (I and.

branch pipe (1, it being impelled by the gas supplied by the branch pipe or. The funnel D is surrounded by a ring-shaped flange (1 applied to its outer edge, so as to prevent the running over of the funnel D and prevent the spattering of the liquid. The funnel D is provided at its lower edge with short legs (1 by which it rests on the uppermost ringshaped tube 9 of a series of similar tubes 9 g, which are arranged vertically below the funnel and vertically below each other in the carbon ating-tank D. The ring-shaped tubes 9 g are each provided at their lowermost portions with a serrated drip-plate 9 of sheet metal, so that the liquid which passes over the same is transmitted in drops onto the next tube g, and so on over all the tubes of the series.

As the liquid is thus conducted in a minutely-divided state through the atmosphere of carbonic-acid gas in the tank D the gas is incorporated with the same, the carbonated liquid being" drawn off through the dischargepipe E, forced through afilter'ER, and finally racked off into the shipping barrels out kegs; Any suitable racking-off faucet can be used The carbonating-tank D is provided with a gage g, which indicates the level of the liquid in the tank 1). The discharge-pipe E is also connected with the bottom of a float-tank H, the float H of which moves up and down in the tank H and operates a rod H provided with pins h that engage the forked ends of 1ever-arms h on the spindles of stop-cocks h 715, which are located, respectively, in the gas and liquid supply pipes A and E. hen, therefore, the level of the liquid in the earbonating tank D rises to a certain level, preferably up to the lowermost ring-shaped tube g of the series 9 g, the float H is raised to such an extent that the stop-cocks 7v 7L5 are closed by the action of the pins h on the lever-armsh whereby the operation of the apparatus is automatically interrupted.- As soon as the level in the earbonat-ing-tank falls the float is lowered, the supply-valves opened, and the operation of the apparatus continued by the supply of liquid and gas to the carbonatingtank.

The advantages of my improved apparatus are that by the primary and secondary mixing of the gas with the liquid a very effective impregnation of the liquid with the carbonicacid gas is obtained, so that the carbonated liquid can be racked off directly into the shipping barrels or kegs, the liquid contain ing a comparatively large quantity of carbonic acid gas Without requiring to pass through the second fermentation produced by the so-called kraeusen process, so that the well-known objectionable features of this latter process are obviated and a fermented liquid of better quality and greater life is supplied.

Having thus described my invention, I claim as new and desire to secure by Letters Patent asset forth;

1.- An apparatus for carbonating fermented liquids, which comprises a gasreceiver, a primary mixing-tank, a carbonating-tank, a gas-supply pipe connecting the receiver with the mixing and carbonating tanks, a liquidsupply pipe for the mixing-tank, a valved branch pipe connecting the gas-supply pipe with the liquid-supply pipe, a pipe connecting the mixing-tank with the upper part of the earbonating-tank, valved branch pipes leading from the gas-supply pipe respectively into the mixing-tank and the supply-pipe, means located at the interior of the carbonating-tank for impregnating the liquid with the gas, and a discharge-pipe leading from the bottom of the carbonating-tank to the racking-off faucet, substantially as set forth.

2. An apparatus for carbonating fermented liquids, which comprises a receiver for the carbonic-acid gas, a primary mixing-tank, a carbonating-tank, a main supply-pipe connecting the receiver with the mixin g and carbonating tanks, valved branchpipes leadin from the gas-supply pipe into the liquid-sup ply pipe, mixing-tank and carbonating-tank, a pipe connecting the receiver with the upper part of the carbonating-tank, a dischargepipe at the bottom of the carbonating-tank, a float-tank connected with the dischargepipe, a float in said tank and means connecting the rod of the float with the stop-cocks in the gas and liquid supply pipes, so as to interrupt the operation of the apparatus when the carbonated liquid arrives at a certain level in the carbonating-tank, substantially In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
