To all whom t may concern.: ized iron, or other suitable material,which has Be it known that We, SAMUEL J. W'ILsoN a series of wells, F, corresponding in number and NAHUM T.

By removing the milk-faucet pacity of the dairy in which it is used. This J, the can may readily be lifted out of its well. cabinet has doors B B and a hinged cover, C, Each can has a flanged l cover with rounded providedat opposite ends with ventilatingcorners and a peaked roof, L, the ridge of aperturesDD, coveredbywiregau'ze andhavwhich is slotted longitudinally, as shown at roo 5o ing sliding doors. In the upper part of the Z, which slot or opening is covered by an incabinet is a tank or sink, E, of zinc, galvanverted-V-shaped cap, M, the sides of which are nearlyv parallel with the roof L, and the lower edges of `which approach the upper surface of the cover, leaving a narrow space between the bottom edges of the cap and the top surface of the cover. The steam and odors from the fresh milk will ascend up through thepening Z, and, condensing on the under side of the cap M, will run down upon the roof L, and off into the water in the sink, so as not to taint the cream and the butter made from it. This construction is clearly shown in Fig.'2.

For cooling purposes either ice or running water may be used. If ice is used, the lid U is closed down after the milk has been strained into the cans, and the sink and its wells packed with ice, and the ventilators D D are opened to permit the current of air passing through them to carry off the steam and odors from the milk; but after this has become chilled thev ventilators should be closed to prevent waste of ice. When running water is used, it is fed to each of the wells in any convenient manner, and escapes through an overflow-pipe at the end of the cabinet. After the cream has set, (with ice this wil-l require from four to six hours, while with water it will usually take from ten to twelve hours,) the skinrmilk is drawn off into the milk-pail through the faucet J, the sediment or impurities contained in it passing out with it. As the cream reaches the bottom of the can, which can be observed through the translucent panes H and I, the faucet is shut and the cream-receptacle is put under it, when it is again opened and the cream is drawn off from the can.

By the configuration of thesink with its wells the sawdust and other impurities in the ice will collect in the forward inclined end of the wells, from which they are readily removed through the faucet K by flushing the sink and wells. There is no waste of ice-space or of water-space, as the case may be; but the best results are obtained in our improved creaming-can with a minimum expenditure of cooling material. By reference to Fig. 2 of the drawings it will be observed that when the cans G are inserted into the tank, with their slanting bottoms extending down into their Irespective wells F, the triangular caps M of the slotted can-covers L project up above the upper/ rim of the tank and above the top of the box or casing A, projecting into the flanged cover C transversely across a line connecting the two draft-openings D D, so that cold air passing between these openings, as indicated by the arrows, will cool off the caps M, thereby keeping them at a constant low temperature, and thus expediting the condensation of the vapors which ascend from the body of cream in the can up into the cap of the cover.

We are aware that it is not new to immerse creaming-cans or milk-cans in tanks or vats conforming to the shape of the can or the immersed portion of the can; nor do we claim such construction, broadly; but by the peculiar construction of the tank with its wells, and ofthe cans, as herein shown and described, we greatly economize the use of ice or ice-water. The tanks and wells may be readily fiushed for cleaning, and both the wellsand the cans may be inspected through the registering-panes I and H, to ascertain the waterlevel and cream-level without opening the top or cover of the cabinet.

We are also aware that it has been proposed to construct a refrigerating-cabinet with a tank provided with a series of depending wells and with cans of similar shape, whereby the processes of refrigeration and milk-cooling are carried on simultaneously, and do not claim, broadly, such construction, but limit ourselves to the constructions shown and claimed.

We claim as our improvement and desire to secure by Letters Patent ofthe United States- 1. The refrigerating box or cabinet A B C, having the tank E, provided with a series of wells, F, and inwardly-sloping portions e e, said wells having straight sides, straight fronts provided with translucent panes I, and sloping bottoms f, substantially as and for the purpose herein shown and set forth.

2. In a milk-cooler, and in combination with the tank A, a series of wells formed of a single sheet of metal doubled upon itself, whereby the various compartments or wells are formed, the said vwells extending the whole width of the metal sheet, and each having a sloping bottom, as set forth.

3. The refrigerating box or cabinet having a tank provided with a series of wells formed of sheet metal doubled upon itself, and having straight fronts and sides and sloping bottoms, in combination with a series of cans having similarly-shaped bottomsV and sides, and arranged at a distance from the bottom and sides of thewells, substantially as described.

4. The combination of the refrigerating box or cabinet having a hinged cover provided with draft-openings, the tank provided with a series of wells, and the cans having longitudinally-slotted covers provided with caps overlapping the openings in said covers, so arranged that said caps will project above the tank and intercept a current of air passing between the draft-openings, substantially as and for the purpose herein shown and specified.

5I In a milk-cooler, a series of narrow rectangular cans, each having an inverted-V- shapedcover with an opening in the apex, covered by a similar inverted-V-shaped cap, whose lower edges approach the upper surface of the cover, leaving a narrow space bef tween the bottom edges of the cap and top surface of the cover, substantially as and for the purpose specified.
