MILK-COOLER.

SPECIFICATION forming part of Letters Patent No. 268,620, dated December 5, 1882. Application filed March 29, 1882. (No model.)

To all whom it may concern Be it known that 1, DAVID N. UALKINS, of

Rochelle, in the county of Ogle and State of .the catch-basin of the cover. Fig. 3 is adetail vertical sectional view of the main cover and supplemental cover in a plane passing through the water-tube and ventilating-tube, Fig. at

-is a sectional view of the water-chamber, representing the milk-can in side elevation, the

covers of the water-chamber being removed. Fig. 5 is a detail view in side elevation of the cream discharge and indicator. Fig. 6 is a detail view in horizontal transverseseotion of the cream discharge device. Fig. 7 isadetail sectional view of the connection of the milkdischarge spout with the milk-can. Fig. 8 is aperspectiveview of the rack which retains the cans in place.

Preferably I make the water-chamber A of wood and line its interior with tin or galvan- Zized iron. Within the chamber are placed milk-cansB,of heightadapted to extend above the overflow-opening a? of the chamber, said cans resting within the rack B, which latter is secured and held to the bottom of the cham- .ber A by the hooks b.

This rack B is composed of the end pieces, b and side pieces, b secured together, as shown, and the latter provided with depending legs or standards 12,

adapted to rest on the bottom of the waterchamber A and afford bearing for the rack. This rack is adapted to fit snugly within the chamberA,and the side and end pieces of the same are separated sufficiently from the re- ,spective sides andends of the chamber A to prevent the cans B, which are secured between the said side and end pieces of the rack B from approachingtoo near the sides and ends of the chamber A, which would interfere with wide enough to admit the cans being introduced therein and long enough for two or three cans abreast, as the case may be. Each can is provided at its lower end with one ortwo projecting tongues, b ,which latter are adapted to rest under the cross-pieces b and hold the can in position. When it is desired to place the cans in position in the cabinet they are turned so as to bring both projecting tongues inside or between two'cross-bars b and lowered to the bottom of the chamber. After they rest on the bottom of the chamber A they are turned so as to bring the tongues under the cross-bars biwhich hold them down firmly in position, whether they are filled or not. The rack 1 3 is secured to the bottom of the chamber A by the books I) and the eyes N. If desired, the cans can be secured in position slightly above the bottom of the chamber A, and thereby enable a free circulation of water under as well as around the cans.

A rubber gasket, f, fits in the sleeve 01, and

through the gasket the milk-discharge tube 9 passes. Disksh, secured to the opposite ends of the tube, fit against the inner and outer ends of the gasket and connect the several parts together. This tubehas free rotary movement in the gasket, and its outer end is pro? vided with a spout, l. r

The main cover 0' is provided with a rim, m, which may be formed hollow or not, as preferred,'and depends into the interior of the Water-chamber. water, forms a water-seal, and an air-chamber, a, is thus formed about the upper portion of the cans. The sides of the main cover are provided with an upwardly-extendin grim, 1", which forms a water-pan on the top of said cover. A tube, 8, extends from the surface of this cover down within the water-chamber to a point below the water-line. The water resulting from This rim, dipping into thethe melting of the ice passes through this tube and into the water-chamber.

O is a rubber cork or stopper, having a metallic or wooden handle secured thereto, which latter, when the cork is in position in the tube 8, extends up through the opening a in the supplemental cover E and is within easy reach of an attendant.

By means of this improvement the water can be retained in the water-chamber'w and allowed to flow downward into the chamber A at suitable intervals without necessitating the removal of the supplemental cover E to accomplish the same end. The coveris further'p'rovidetl at one end with a ventilating-tube, t, whose lower extremity communicates with airchamber n at a point slightly below the top of the milk-cans, as indicated by the dotted lines in Fig.3, so as to be automatically closed when the water rises sufficiently to submerge the lower end thereof. By this means the water is prevented from rising above thi'spoint (the cover being air-tight) and flowing'over into the milk-cans. The upper extremity of the tubet extends above the water-rim of the supplemental cover. The rear side of the main cover 1 is provided with a catch-basin, D, which extends across the cover and is adapted to catch the water which may be on the cover as the latter is swung back on its hinges.

The supplemental cover E is formed with a depending flange, to, about its sides. This flange rests upon the main cover and forms a water-space, 00, between the two'covers. The ventilating-tube passes through a hole, y, formed in the supplemental cover.

The double-walled upright cylinder F is formed at the central portion of the supplemental cover and extends through the same, and is provided with a bottom, which rests slightly above the top of the main cover, The top of the cylinder is provided with ahollow removable cover or lid, G. The ice is placed .in this cylinder and'rests on the bottom thereof, which keeps the water in the Water-space 00 cold, and thereby maintains the milk at a cool temperature. The water from the ice is allowed to escape from the cylinder F through the perforations' 6 into the water-space w.

D is an overflow-tube, rigidly secured'to the main cover near one end of the cooler. The upper end of this tube extends up slightly above the top of the cover, and the lower end terminates near the bottom of the chamberA'. This overflow-tube prevents the water from rising in the space at and running over the top of the cooler should the plug or stopperC be allowed toretna-in too long in the tube .9.

p The upperporrion of the milk-can is provided with a plate, H, fitted over a vertical opening formed in its side. The plate may be of glass or other transparent substance, whereby the line of division between the cream and the milk cans can be seen. The side of the milk-can is further provided wlth a curved opening, a, formed in a vertical plane, and having itsex- 'tremities practically in transverse line with the extremities of the transparent plate. A circular recess, b, is formed on the outer side of the milk-can, and within this recess is centrally pivoted a vertical disk, L. This disk has a knob, 6, for rotating it, and is further provided with a discharge-spout, 61, located near the periphery of this disk. This spout and the curved opening a are both formed at the same distance from the pivoted center of the disk, so that as the latter is rotated its spout is always in line. with said curved opening. By turning the disk its spout is correspondingly moved to different heights, and by adjusting the spout in horizontal line withthe line of division between the milk and cream, as shown through the transparent plate, the cream can be drawn off from the milk.

When this improved cooler is used without the employment of ice the cork O is kept in the tube 8, and the water (which is forced onto the top of the supplemental cover bywind'mill, pump, or any other suitable means) allowed to flow on top of supplemental cover and fill the main cover up to the top of the overflow-tube. overflow-tube down to near the bottom of the chamber A, and passes from the cabinet by a waste-pipe situated slightly below the level'of the top of the cans. By this means a constantcirculation is kept up, which answers all'the necessary purposes. 7

In the foregoing specification I have 'described and in the drawings have shown several parts of a milk-cooler patented to me October 26, 1880;-but I would have it understood that I do not limit the use of my im- The water then flows through this provement claimed herein to the peculiar construction of the can and other parts shown and described but not claimed, as I consider myself at liberty to use any other construetion of parts that will answer the necessary purposes.

Having fully described my. invention, whatI claim as new, and desire to secure by Letters Patent,'is-

1. In a milk-cooler, the combination, withi'a water-chamber and milk-cans, of a'co'ver having a depending rim which extends into the water'chamber, a ventilating-tube extending above the cover and below the top of the cans, and a tube which conducts the waste ice-water from the surface of the cover into the water-chamber. I

2. In a milk-cooler, the combination, with the Water-chamber and milk-cans, of a cover having an inwardly-extending rim, and provided with a pipe adapted to convey the waste icewater from the surface of the cover, a rubber plugor stopper adapted to fit said opening, a ventilating-tube passing through saidcove'r to a point below the top of the cans, and an overflow-pipe extending nearly to the bottom of the chamber, substantially ass'et forth.

3. In a milk-cooler, the combination, with'a water-chamber and a cover provided with ventilating and waste-water tubes, of asupple mental cover provided with a central upright cylinder having an independent bottom on which the ice rests, and perforations for the when the parts are in position,substantially as set forth.

I 4. In a milk-cooler, the combination, with the water-chamber, of the rack removably secured to the bottom thereof, and provided with side pieces adapted to prevent the cans from being placed too near the sides and ends of the chamber, so as to interfere with the closing of the top, cross-bars, and cans having lugs adapted to engage said cross-bars, substantially as set forth.

5. The combination, with the water-chain ber, of a rack removably secured therein, the said rack being composed of side and end pieces, depending hangers, standards, and

dle by which it can be passed through the supplemental cover and close the Waste-pipe without removing either cover, substantially as set forth. v

In testimony that I claim the foregoing I have hereunto set my hand this 20th day of 7 March, 1882.

DAVID N. OALKLNS.
