APPARATUS FOR COOLING AND PRESERVING BEER.

SEGIFICATON formng' part of Letters Patent NO. 667,O4, dated February 5, 1901.

Application filed June 17, 1899.

TO all whom ;it may concerns Be it known that I, ALFRED COBLEY, a citizen of the United States, residing at Irvington, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Apparatus for Cooling and Preserving 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 letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to increase the pressure in partly-emptied kegs of beer without at the same time raising its temperature or permitting the introduction to the beer-cask of noxious gases or the seeds of disease, such as are commonly found in the interior oi' a saloon, where a large number of men are congregated smoking, expectorating, &0.

The invention consists in the improved means for introducing cold, compressed, invitiated atmospheric air to the keg and in the arrangements and conbinations of parts of the same, all substantially as will be hereinafter set forth and finally embraced in the claim.

Referring to the accompanying drawings, in which like letters of reference indicate corresponding parts in each of the views, Figure 1 is a sectional View of a portion of a building containing a bar and showing the relation of the various pipes,valves, the., conprising my improvements to the said bar and kegs from which the drinks are dispensed. Fig. 2 is a detail side elevation, partly in section, of an air-pump of my improved Construction.

In said d rawings, a indicates the fioor of a building, above which is arranged the bar Z), having the ice-box c, of any ordinary construction.

dindicates the air-pump, by means of which the open air is forced into a reservoir e through a pipe f, said reservoir ordinarily being stationed below the fioora in the cell-are beneath the saloon. g indicates a pipe leading from said reservoir upward to the bar, where it is provided with a pressure-indicator h, by means of which the barkeeper may see Serial No. 720,887. (No model.)

the condition of pressure in the cask or kegs at any time.

From the indicator h the pipe ?I returns to the cellar, where it is in connection with a common pipej, provided with suitable pipe connections, by means of which the fiexible branch pipes or tubes Ic k are connected to the kegs ZZ. The kegs Z are provided with suitable bung valves or faucets m, adapted to receive the pipes 75 76 and pipes o, through which the beer or other liquid is conveyed upward to the bar, the said pipes o o passing through the ice-box c, where the said pipes are properly coiled in any ordinary manner to cool the beer passing therethrough,and the beer is ready to be dispensed to the customers.

Heretofore the air-pump d has opened directly into the saloon and taken th e air thereof, and because of the impurity of such air, due to the presence of smokers and other vitiating causes, there has been a reduction in the purity of the beer, and because of the heat of the saloon the same has caused an unnecessary heating of the beer, requiringa greater supply of ice to counteract the effect. By my improved construction I connect to the said pump d a pipe 10, which eX- tends through the ice-box c, where it is turned into a coil q to cool the air passing therethrough, and thus a supply of cold airis furnished, which is cooled before it passes into the pump and reservoir c. From the coil q the pipe extends out from the ice-box and opens into the atmospheric air outside of the saloon. The air thus introduced to the beer is free from contaminating influences above referred to and is initially cooler than the saloon air and is further cooled by the air or ice in the ice-box before being sent into the cellar. When it arrives in the beer-keg, it is still at a low temperature and tends to keep the beer fresh and pure, preventing an acetic fermentation of the beer, due to a high temperature.

The pump dis provided at its lower end not only with a valved nozzle or connection r for the pipe leading to the reservoir, but is also provided at a point opposite said nozzle or connection with a second nozzle or connection s, in which is inserted a check-valve t. Said nozzles are each furnish ed asecond valve u u', operable by means of a handle, by means IOO of which should the cheek-valve get out of order the connection with the outside air and coil v may be eut ofi' and the pump employed in the ordinary manner, taking its air from the inside of the saloon.

Instead of the hand-operated pump d shown for compressing the air it will be obvious that the eooled air might be forced into the supply-tank or the eask by other means commonly employed, such as by water-pressure or the like. Any suitable method of indueing a flow of air may be used, this feature constituting no part of my invention.

Having thus described the invention, what I claim as new is- The heroin-described apparatus for cooling beer for a bar-room without impregnating it with inpurities, eombining With a bar, an icebox arranged beneath said bar, a keg or other supply-reservoir for the beer, abeer-pipe leading from the lower part of said keg or reser- Voir through the ice-box and terminating at the bar above said iee-box in a faueet for drawing the bee', an air-pipe leading intd the top of the beer-keg from a compressionohamber, an air-pump having a dischargepipe leading into said eompression-chanber and an inlet pipe, said inlet-pipe extending from said pump through the ice-box and through the wall of the bar-room, its open extremity thus lying outside the bar-room and taking in air free from the oontaminations of the bar-room, andthat portion of the pipe intermediate of its ends which passes through the ice-box being eoiled to cool the air drawn from outside the bar-room, Whereby cold pure air is pumped into the beer-keg, substantially as set forth.

In testinony that I claim the foregoing I have hereunto set my hand this th day of June, 1899.

ALFRED COBLEY.
