FERM ENTlNG-T'RAP.

SPECIFICATION forming part of Letters Patent No. 541,443, dated June 18, 1895.

Application filed April 4, 1895. Serial No- 544,s99. on model-l To all whom it may concern:

Be it known that I, EMIL MARQUARDT, a citizen of theUnited States, residing at Brooklyn, Kings county, New York, have invented 5 certain new and useful Improvements in Fermenting-Traps; 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.

My invention relates to the art of fermenting alcoholic beverages, and more especially to the art of vinous fermentation.

The object of the invention is to provide a device in the nature of a trap, to be placed upon the bung or vent of the cask containing the liquor in a state of fermentation, and which is designed, first, to prevent the escape at ordinary pressures of the gases generated in the process of fermentation, such as carbon monoxide and carbon dioxide, alcoholic vapor, 850., from the cask, which would, otherwise, fill the cellar or other space wherein the same is situated, while, at the same time, it will permit the escape of such gases, if, as sometimes happens, they acquire a dangerous pressure; secondly, to form a receiver for the scum, foam and dirt as the same is cast forth from the barrel during the fermenting process, which shall effectually prevent the return of such scum, 860., into the barrel, and, thirdly, to prevent the admission to the interior of the barrel or cask of flies and other vermin, dirt, &c., which would otherwise be apt to find admission to the same, especially during warm weather.

With these objects in view, a fermenting trap constructed according to my invention comprises a tubular, hollow bung, adapted to be inserted into the bung hole of the cask and provided with an upper, enlarged, preferably cup-shaped receiver, into which the tubular bung extends sufficiently to form an annular receptacle within the cup shaped enlargement. In connection with these elements, my invention comprises a lid provided with an outer depending perforate flange and with a depending annular flange adapted to dip into the annular receptacle so as to extend down to or near the bottom of the same, said de pending flange being provided with cut-away portions, so as to allow the outer and inner annular spaces formed by this depending flange, to communicate.

' My invention, moreover, consists in such further features, elements and combinations 'of parts as will be hereinafter more fully set forth, and pointed outinthe claims.

In the drawings accompanying this specification, I have represented a fermenting trap embodying my invention in its preferred form.

In the drawings, Figure 1 represents a vertical longitudinal section of the trap; Fig. 2, a perspective view of the same,the lid being shown as removed for the purpose of giving access to the interior; and Fig. 3, a detail view, in vertical section, of the lid.

Referring to the drawings, A represents a cup-shaped scum-receiver or enlargement, and B a tubular sleeve or bung extending downward below the cup-shaped receiver, as shown at b, and preferably tapered somewhat, as shown, so as to be readily inserted into the bung or vent of the cask, O, and to fit snugly therein,so as to completely close the same. This tubular sleeve, as shown, extends upward a considerable distance into the cupshaped receiver, as at b, so as to form, within the cupshaped receptacle, an annular space or-receiver for .the scum, dirt and other matter ejected from the barrel during fermentation. This cup shaped receiver, as shown, is provided with a lid, D, having a depending flange, E, which dips down into the annular space between the sleeve, B, and the outer wall of the cup-shaped enlargement, thus dividing the said annular space into two annular vided with a series of perforations,f, whose purpose will be hereinafter set forth. The lid, D, is, moreover,provided at its top with a window, G, made of glass or other transparent material, which permits inspection of the interior of the fermenting trap. If desired, the trap may be provided with a handle,

H, of any desired form, for the purpose of readily lifting the same from the cask when it is desired to remove the contents which have accumulated therein.

The operation of the fermenting trap so described is as follows: The lid, D, having been put into place, the trap is fitted to the cask by inserting the lower portion, 27, of the sleeve, 15, into the bung hole. A little water or other suitable liquid is then poured into the amin lar space in the cup-shaped receiver, A, and the lid, D, is then placed in position on the same. The cask is now effectually closed ofi from the outer atmosphere. As the fermentation proceeds, the gases which are evolved in the cask are first absorbed by the liquid in the receptacle and their further escape is then prevented by the closed trap. When the fermentation becomes more violent, the scum, foam, grape-skins, and other refuse, as they are ejected from the cask are caught first in the annular space, e, surrounding the sleeve, B, and finally the pressure of the gasesin the cask causes the same to be forced through the cut away portions or ports, (2 into the outer annular chamber, e, where they are held by those portions of the depending flange lying between the ports and gradually accumulate. lVhen the accumulations of dirt, &c., have become considerable, which condition canbe readily ascertained by inspecting the interior through the window, G, the lid, D, is removed and the cup-shaped receiver withdrawn from the cask, when the contents can be readily thrown out and the parts can then be put into place again, to operate as before. On the pressure of the gases in the cask becoming too great, they are. allowed to escape automatically, by raising the lid, when the gases can pass through the perf0rations,f, into the outerair. The apparatus thus acts as asafety valve, and effectually prevents the scattering of the refuse and, perhaps, a portion of the liquids from the barrel around the same. \Vhen the pressure has subsided sufficiently, the lid can again be closed.

The advantage of the fermenting trap so described are various. In the first place, under the same, the gases from the cask, whose escape at ordinary pressures has hitherto been a source of great annoyance, are effectually held within the cask,and the air in the cellar or other space within which the same is located is kept pure and uncontaminated. Moreover, the gases are prevented from escaping from the fermenting liquor, thereby preventing the same from becoming weak, and

of low alcoholic strength. In the second place, the construction embodying my invention forms an effectual catch for the scum and other waste matter ejected from the cask, and avoids all danger of the same being returned to the cask, and, moreover, prevents the same from being spattered over and beyond the barrel. It, moreover, forms a receptacle which is easily manipulated, and from which the waste matter, as it accumulates, is readily removed. Thirdly, it completely seals the cask against the admission of all foreign matter, flies, vermin, (be.

' What I claim, and desire to secure by Letters Patent, is-

1. In a fermenting trap, the combination, with a receiver having a tubular bung projecting below the receiver and also extending upward into the same, of a lid provided with a perforated flange extending into the receiver and fitting against the inner wall of the same, substantially as set forth.

2. In a fermenting trap, the combination, with a receiver having a tubular bung projecting below the receiver and also extending upward into the same, of a lid provided with a downward-extending flange projecting into the receptacle between the bung and the wall of the receiver, and with a perforated flange extending into the receiver and fitting against the inner wall of the same, substantially as set forth.

3. In a fermenting trap, the combination, with a receiver having a tubular sleeve extending into the same of a lid provided with a flange extending into the receiver and litting against the inner wall of the same, said flange having a series of rows of perforations, substantially as set forth.

4. A fermenting trap comprising a receiver provided with a tubular sleeve extending into the same and partially below the same, in combination with a lid provided with a depending flange extending into the annular space between the tubular sleeve and the outer wall of the receiver and having ports at its lower edge, the said lid being also provided with an outer depending and perforated flange, all substantially as and for the purpose set forth.

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