SPECIFICATION forming part of Letters Patent No. 609,053, dated August 16, 1898. Application filed September 24, 1897. Serial No. 652,821. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD-SHERIDAN, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Cooling Apparatus for Air-Tanks, of which the following is a specification.

My present invention relates to a new and useful improvement in coolingv apparatus for the air tanks or chambers of beer and similar elevating devices, and has for its object to provide an effective means for cooling the air after being compressed and prior to its entering the beer-kegs in order that the beer may not be deteriorated by the inflowing of air above the proper temperature.

A further object of my invention is to effect economy in the cooling of the beer.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claim.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specifi cation, in which- Figure 1 is a section of an apparatus made in accordance with myimprovement, show ing a beer-barrel connected with the air-tank 5 Fig. 2, a front'elevation of the apparatus;

and Fig. 3, a detail of the one end of the tank,

showing a slightly-modified manner of secur ing the cap or head thereon.

In carrying out my invention as here embodied, A represents the tank or air-chamber, which may be of any convenient construction and design, but preferably that shown and described in my allowed application, Serial No. 597,800, filed July 1, 1896. A suitable flexible pipe K is attached to the spigot L of the tank at one end and to a drawing-faucet M at the other end, said faucet being fixed in the barrel N in any well-known manner,"

Upon the tank A is plaeed an ice-receptacle B, which may be made of any material-as, for instance, sheet metal-and this receptacle is of rectangular shape, having no bottom thereto and its lower edges scalloped, as in dicated at C, so that when resting upon the top of the air-tank the water which comes from the melting of the ice may freely flow therefrom and down the sides of the tank and finally drip into the trough D, which is arranged beneath the tank and is set upon such an incline as to cause the water caught thereby to be conveyed to the drainpipe E and from thence to any suitable outlet.

The trough Dis here shown as formed of sheet metal and secured to the ice-receptacle at the back thereof, extending around the airtank, so as to prevent the escape of moisture from this side of the tank to the wall or sur* face against which the tank is secured, and

in practice this is found of considerable importance, as there is a liability for small pieces of ice or other foreign substances to accumulate back of the tank, which would transfer thewater flowing downward around the tank to the wall. I

.Suitable doors F are provided for gaining access to the receptacle, thereby permitting the ice to be readily placed therein or the ap paratus thoroughly cleaned when occasion requires.

It is a well-known fact that cold water pass ing in thin sheets over an exposed surface will effectually reduce the temperature of the surface" even to agreater extent than ice brought into direct contact therewith, and in my present improvement I utilize this prin putting the icein direct contact with the airtank, but in also permitting the water which is formed by the melting of said ice to constantlyfiow in thin'sheets over the surfaces of the tank, and in practice it has been found that the temperature of the air passing through the tank A is greatly reduced, and this notwithstanding the fact that the compressing of the air tends to raise its tempera ture.

Another important feature of my invention is that the drippings from theice after having performed the function of cooling the tank are caught in the troughand conveyed there from to a suitable drain-pipe, ,thusin nowise interfering with the surroundings of the ap paratus, thereby permitting the placing of the apparatus in any desired locality.

In Fig. 3 I have shown the head or cap I-I arranged so. as to be bolted to the flange I, formed upon the tank by means of a series of bolts J, and this arrangement gives better access to the tank than when the cap is threaded thereon, as will be readily understood.

Of course I do not Wish to be limited to the exact construction and arrangement here shown, since these may be varied within certain limits without departing from the spirit of my invention, which rests in the broad idea of combining an ice-receptacle with a pressure air-tank and utilizing the water formed by the melting of the ice for the cooland a drain-pipe leading from the lowest point of the trough, as and for the purpose described.

In testimony whereof I have hereunto affixed my signature in the'presence of two subscribing witnesses.

EDWARD SHERIDAN.
