No. 276,088; I Patented Apr. 17,1883.




SPECIFICATION forming part of Letters Patent No. 276,083, dated April 17, 1883.

Application filed J nnc 1, 1882. (No model.)

To all whom it may concern Be it known that I, CHARLES SoHUNcK, a citizen of the United States, residing at Green Bay, in the county of Brown and State of Wisconsin, have invented certain new and useful Improvements in Apparatus for Regulating the Fermentation of Beer; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to improved apparatus for regulating the fermentation of beer; and it consists in the construction and arran gement of devices, as hereinafter more fully described and claimed.

In the annexed drawings, illustrating the invention, Figure 1 represents an end elevation of a series of casks with my improved bunging apparatus attached thereto, so as to connect said casks and conduct the excess of carbonicacid gas away from the cellarorroom in which thefermentation is effected. Fig.2 shows sectional details of my improved bung. Fig. 3 is a similar view of the same, showing the devices for modifying or retarding the pressure as applied to one barrel or cask. Fig. 4 is a side elevation, partly in section, of my improved devices for modifying the pressure; and Fig. 5 is a section and end view of aslotted tube forming a part of said devices.

Like letters of reference are used to designate the same parts in the several views.

In arranging the details of my invention the fermenting-casks A are provided with bungs or bung-faucets B, as shown in Fig.1. These bungs are provided with openings having tubular projections or nozzles a for the attachment of the flexible tubings b I), which connect the several casks of a series, each separate tube 1) being provided centrally with a cook or faucet, c. The bung inserted in the last or farther cask of the series requires only one of these nozzles a, while the bungs inserted in the other casks of the series require two. The tubes 1) are arranged to permit the escape of any excess of carbonic-acid gas generated by the fermentation of the beer, the removal of which gas, together with the heated air, tends to purify and ventilate the beer, thereby rendering it mild. To one of the nozzles to of the bung inserted in .the first cask of the series is attached a flexible tube, d, that communicates with a T-tube, O, which is provided with cocks e 6, between which is placed a tube communicating with the pressure-gage D, which has a dial and index for indicating the degree of pressure exerted by the carbonic-acid gas. In the end of the gagetube 0, to which is attached an exit pipe, f, leading from the fermenting-apartment, and partially surrounded by said exit-pipe, is arranged a slotted tube, E. This slotted tubeis externally screw-threaded, so as to be turned into its seat, as shown in Figs. 3 and 4: to a greater or less extent, thereby exposing more or less of its slotted sides and modifying or retarding the flow of gas, so as to lessen or increase the pressure within the casks. The bungs B are each provided, in addition to the nozzle a, with a nozzle, h, for the attachment of a tube, i, used for racking off the beer when required. Each bung is also provided with a two-way cock, k, that may be turned so as to govern the various exits as desired.

It will be seen that by this apparatus an exit is afforded for the escape of the excess of carbonic acid, while its pressure is readily regulated by simply manipulating the slotted tube E.

By attaching the slotted tube E to the bungnozzle h of any one cask, as shown in Fig. 4, the advantages will be the same, the indicator D, attached to the nozzle a, serving to show the degree of pressure from time to time, in the same manner as when the apparatus is applied to a series of casks.

By this arrangement of devices beer can be racked off from any one of a series of casks and the emptied cask be disconnected from the series withoutdisturbing the remainingcasks.

It will be seen that when the apparatus is employed with a series of casks the cooks e 6, attached to the gage-tube (.l,may be turned so as to cut oil the gas entirely or break the force of its exit. The cocks c and k are used to control their respective passages according to circumstances. The various devices are simple, convenient, and readily applied, and may be used with any number of casks.

5 Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The combination of a series of casks, A A, bungs B, having two-way cocks 7c, nozzles to a IO and h, the tubes 1) I), provided with cocks c, the

gage-tube 0, having cocks e c and tubes d], the indicatorD, slotted tube E, and flexible tube 2', as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
