MILK-COOLER.

To all whom 'it may concern: i

Be it known that I, EMMA L. WALLACE, a citizen of the United States, residing at Halsey, in the county `of Linn and State of f Oregon, have invented certain new and usey ject of the present invention to provide a cooling apparatus of this kind which can be `easily cleaned and thus kept in thorough sanitary condition, and also to provide imrovedmeans for supporting thereceptacles 1n the vessel.

A further object of theinvention `is to provide a cooler embodying certain novel featuresof construction to be hereinafter de- `scribed and claimed.

wall of the vessel, and support-`the cover inV open position. A has -and-staple lock for. i o i In the vaccompanying drawings forming a part of this specification- Figure 1 is a plan View of the cooler with the'cover thereof thrownopen. Fig. 2 is a transverse section with the cover closed. Fig. 3 is a longitudinal section showing the milk or cream holding receptacles within the cooler. Fig. 4 is a perspective view of one of the holding devices hereinafter referred to. i x

Referring specifically to the drawings, the vessel which contains the c00lin medium comprises a front wall 10, rear an lend walls 11 and 12, respectively, a' bottom 13, and a hinged cover 14. The cover is double-inclined and seats on the top edges of the lfrontprear and end walls, and said cover also hasa depending bottom lange 15 fitting snugly i against the Iinner surface of said walls soas to make atight inclosure. The hinges of the ,cover areiindicated at 16. In theend walls of the cover are Ventilating holes 17 to permit the escape of any heat rising from the cooling milk `or cream, and also to allow fresh air to circulate through the apparatus. To the free ends of the cover are connected chains 18 which are fastened to the frontthe cover is also provi ed. f

On the bottom of the vessel are transverse strengthening 'stri s 19, vand wooden supports 20 are provi ed on which the vessel lLs removably sup orted. D `At 21 is in icated the inlet pipe of the Speci'cation of Letters Patent.

cooling agent, said pipe being connected to one of the end walls of the vessel near the top thereof. This pipe may be connected to` a suitable source of water supply. If running water is not available, the vessel may be filled through a funnel 22 attached to the inletv pipe. An outlet pipe 23 is'connected to the opposite end wall near the bottom of the vessel, and an overflow pipe24 is `also connected to said wall slightly below the level of the inlet pipe. The overflow pipe'is connected tothe outlet pipeand the latter is also provided with a valve 25 which is located between the vessel and the point at which the overflow pipe joins the outlet plpe. i

On the front and rear walls of the vessel, inside the latter, are shelves 26 for the cansupporting frames to be presently described. These she ves are formed b foldin over the material. of which the ront an rear walls ofthe vessel are constructed, the fold being downwardly along the inner surface of said walls for a short distance, as indicated at 27, and said downward fold vterminates in an outward horizontal bend a suiicient distance to form the shelf, said outward bend terminating in a return` bend beneath the shelf, thus doubling the same, the end of the material being soldered to the shelf. This construction makes the top edges of the front and rear walls perfectly smooth and at the same time forms strong and rigid shelves. Braces 28 for the shelves are also provided. D The can-supporting members comprlse a frame composed of an lron rod` which 1s 'bent to form an intermediate circular por- 'milk or cream seats in the intermediate circular portion 2 9 ofthe frame, the handles 34 of the can engaging the top thereof, and holding the can in place within the frame. On the shelf of the front wall are mounted. latches com rising screw hooks 35 which --are 'adjusta le to engage over the transverse portion 31 of the frames and thus hold the same down when removing the cans therefrom.

The cans 33 have perforated covers 36 in` order to permit the escape of the heat which rises from fresh milk or cream, and at the same time to prevent the crea-m'from drying which occurs when standing entirely uncovered.

The entire apparatus herein described,

except the milk or cream cans', will-be constructed of galvanized metal, and as all parts are readily accessible,l the apparatus can be thoroughly cleaned and kept in sanitary condition. The interior of the vessel is accessible upon swinging the can-supporting frames upwardly on their hinges. The cans will be made of extra heavy tin.

I claim: u Y

l. An apparatus of the character ydescribed comprising a vessel having an inlet and an outlet for a tempering agent, shelves on opposite sides of the vessel on the inside and below the top thereof, and receptaclesupporti-ng frames each comprising an inter- I mediate circular portion, and end portions, one of said end portions being hinged to one of the aforesaid shelves, and the other end portion being supported on the other shelf.

2. An apparatus of the characterV described comprising a vessel having an inlet and an outlet for a tempering agent, shelves on opposite sides of the vessel on the inside and below the top thereof, said shelves being formed by bending the material forming- Asaid opposite sides of the vessel inwardly and downwardly, said bends terminating in lhorizontal bends at the extremities oi' whleh return bends are made, said horizon.-L

tal and return bends forming the shelves,

and receptacle-supporting frames mounted` on the shelves. In testimony whereof I aiiix my signature in presence ofltwo witnesses.
