All those light kinds of beer, and other liquids, which cannot be drawn through an engine, while the barrel remains i n the coolness of the cellar, but must be at hand that the fresh glasses may be drawn from the wood itself, are certain to get very warm in summer, and there is nothing so thoroughly nasty as warm "lager." By the use of this cooler it is always kept sparkling, fresh and clear. This invention is intended to be a portable refrigerator for barrels, and it can be easily lifted from one to the other. In our engravings, Fig. 1 is a perspective view of one fitted on a barrel, and Fig. 2, a section. A is the stand, and B the barrel, C be- ing the refrigerator made of zinc or similar metal. It is divided into two compartments, in the one, a, is placed the ice, at the end of which are two channels, b, through which the water can run off; c is the other compartment, in which is placed plaster of Paris or some non-conducting substance, and has two holes, d, through which it can be filled. There is also a cut-off arrangement seen at e, keeping the space over the bung free, so that the bung can be easily pulled out to allow the liquor to run. It was patented Sept. 15th, 1857, and further particulars may be obtained by addressing the agent, A. Lippman, 96 Eldridge street, New York.
