UNITED STATES PATENT OFFICE.

JEAN SOHAFHAUS, OF NEW YORK, N. Y.

SWIMMING BEER=COOLER.

SPECIFICATION forming part of Letters Patent No. 280,405, dated July 3, 1888.

Application filed April 10, 1883. (No model.)

To all whom it may concern.-

Be it known that I, JEAN SCHAFHAUS, a citi-. zen of the United States of America, residing at New York city, in the county of New York and State of New York, have invented certain new and useful Improvements in Swimming Beer-Coolers; 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 that class of coolers used in cooling beer while in fermenting-vats, the object of cooling the beer being the preserving of the saccharine matter therein and to retard the germination of the carbonic-acid gas.

My cooler is expressly so constructed that the utmost cooling-surface is obtained.

I am aware that swimming coolers have heretofore been used; but none, to my knowl edge, have the cooling-surface that I obtain by my construction.

The coolers heretofore used were constructed in the shape of an ordinary cylinder provided with a bottom, while mine is constructed of two shells, and in such manner that a double cooling-surface is obtained.

I 11 the old style of swimming coolers it was necessary to weight the bottom, so as to pre vent the tipping of the cooler, while those con structed after my plan are prevented from tipping by the means of the water-column which enters the space (1..

Figure 1 represents a vertical section of a vat with my improved swimming beer-cooler in position. Figs. 2. 3, and 4 are modifications of the swimming beer-cooler.

In the drawings, A represents the fermenting-vat; B, the cooler; 12, the outer shell; I)", the inner shell; I), the ring or rim, which latter, however, may be dispensed with, it not being a vital part of the invention.

Of course these coolers may be made of any suitable material or form, and suitable means may be provided for lifting the coolers when necessary. 7

When it is desired to counterweight the coolers for the purpose of preventing any possibility of tipping the same, it is only necessary to fasten the weights in the drawings at X.

The manner heretofore adopted in practice of employing the swimmers without lifting them out of the fermentingvat for the purpose of filling them again with ice was to simply use a hose as a siphon.

By means of the coolers as constructed according to my plan I have been enabled to cool the contents of a vat in .one-half of the time heretofore required. This is of great consequence, since the longer the beer, after it has reached the fermenting state in its process of manufacture, remains in a temperature of, say, 8 or 9 Reaumur, the greater the loss of saccharine matter, which is very detrimental. The great object sought to be brought about by the use of coolers is the immediate (if it were possible) reduction of the temperature of the beer. The vessel or cooler may be filled with ice or cold water, as desired.

In Figs. 2, 3, and 4. I have shown modifications of form of my cooler.

I prefer the construction of a cooler as shown in Fig. 1, since it is obvious that the coolingsurface is much greater than that shown in the V v modification.

'When desirable, I construct the coolers with a ring or pipe, 0, soldered on the outside upper portion, as shown in Fig. 3.

' I am aware that swimming beer-coolers have been used and patented; but they differ in construction from mine, and I disclaim them; but

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

1. The swimming beer-cooler B. having the shell I) and b", said shells being united at their lower ends, as shown, and having the rim If, in combination with the balanceweights X and chains, arranged substantially as and for the purpose set forth.

2. The swimming beer-cooler B herein de scribed, consisting of the shells b and I)", united at their lower ends, as shown, in combination with the balance weights X and chains, and the ring 0, arranged as and for the purpose set forth. v

3. The swimming beer cooler B, having shells b and b and a conoidal space, a, in combination with the balance-weights X and chains, arranged substantially as specified.

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

J EAN SOHAFHAUS.
