Nov. 25, 19307 H. E. CANN MILK COOLER- Filed March 24,
Patented Nov. 25, 1930 UNITED STATES HARRY E. CANN, OF WEST (L'HESTEB, PENNSYLVANIA MILK- cooLEn Application filed larch 24, 1928. Serial N0. 284,405.
I I v i TlllS invention relates to new and useful improvements 1n coolm devices, and partlcularly to devices for coo mg liquids, and especially milk. Y
6 One object of the invention is to provide a container, or cabinet, which contains water at a predetermined level, and into which water receptacles, containing milk, are placed, a refrigerant conveying coil being arranged in 10 the cabinet in such manner that the greatest efficiency, tending to lower the temperature of such water, and the contents of the receptacles, is obtained.
Another object is to so arrange the coil,
and to so proportion the water, with respect to the quantity of milk, in the receptacles, that the temperature of such milk will be lowered to the desired degree, in the least possible time.
Another object is to so construct the cabinet, and to so dispose the coil that the air above the water, when no receptacles are therein, will be maintained at a low temperature, thereby obviating the waste of energy of cooling the water, so that such 'cooled water will cool the air thereabove.
Other objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.
In the drawing:
Figure 1 is a top plan view of the cooling cabinet, the cover being removed.
Figure 2 is a vertical longitudinal central sectional view through the cabinet, the milk receptacles beingremoved.
Figure 3 is a vertical transverse sectional view on the line 3-3 of Figure 1, showing the receptacles in the cabinet, and the risen water 0 level.
Referring particularly to the accompanying drawing,'there is shown a cabinet 10, having the water-proof and heat insulating lining 11, and having the cover or lid 12. A pipe 13 is connected with the end wall ofthe ca inet, to convey water out of the cabinet. A slatted, and removable floor 14 is disposed in the cabinet, on which the milk containers 15 are arranged to stand, and surrounding the receptacles, is a supporting rack comprising the water. The level of the water, w ing the same in the cabinet, is determined by the displacement of the milk receptacles, so
the uprights 16, each having the notches 17 in their inner edge faces, and the notches 18 in their outer edge faces. Seated in the inner notches 17 are the rails 19, of the'rack, an inclined rail 20 being secured to the upper beveled ends of said uprights. Supported in the outer notches 18, of the uprights 16, are the convolutions of the refrigerating or cooling coil 21, the ends of which extend respectivel throu h the upper and lower 60 portions 0 the en wall of the cabinet, and are connected withthe coil and pump of the. refrigerating unit 22. It will, of course, be understood that the refrigerant is forced through the upper convolution of the coil,
and passes down and out through the bottom coil. This is done for the obvious reason that evaporation of the refrigerant begins in the upper coil.
In the o eration of the device, water is permitted to ow into the cabinet until the level is below the uppermost convolution of the coil 21. The receptacles 15' are then placed in en placthat when the proper number of the receptacles are submerged in the water, the water level will rise to cover the uppermost convolution of the coil, and leave such convolution uncovered when the cans are removed.
I have found, by-experiment, that the fol-' lowing conditions and data must be observed: Where the cabinet is built to accommodate three cans or receptacles, which contain, in the aggregate, fifteen gallons (15) orisixty (60) quarts of milk, approximately one hundred andnine (109) gal one of water must be placed in the cabmet. The combined d1splacement of the three cans will cause the water level of the above named gallons, to
rise so as to submerge the uppermost convolution of the cooling coil. Thus the heat is absorbed by the water, from the cans, and such heat absorbed by the refrigerant in the vcoil. The purpose of using the above-named numberof gallons of water, to the'said number of gallons of milk, permits the uppermost convolution of the cooling coil to cool the air above the water, when the cans have been removed, thereby rendering the interior of the cabinet, especially above the water, much colder than were the said convolution to remain submerged in the water. In the latter event, it would take considerably longer to lower the temperature of the water, and subsequently the milk, hence the uncovering of the upper convolution, when the milk receptacles are removed from the cabinet. Thus, when new receptacles, containing milk, are
laced in. the cabinet, the process of cooling begins at a much lower temperature .than would be the case where the uppermost convolution of the cooling coil to remain, at all times, submerged in .the water.
Attention is also directed to the fact that the slatted floor, as well as the rail, may be readily removed from the cabinet, when desired, and that such rail properly supports the coil, and maintains the receptac es in place.
What is claimed is:
1. A cooling device comprising a cabinet, a support in the cabinet including uprights located near each of the walls of the cabinet and at right angles to the respective wall that each is near, said uprights having recesses in their opposite edge faces, rails extending between the uprights and seated within the recesses in corresponding interior faces thereof, a heat absorbing liquid in the cabinet, and a refrigerant conveying coil having its convolutions seated within the other recesses and completely encircling the support, said heat absorbing liquid being so proportioned with respect to the displacement of receptacles to be cooled that are submerged in said liquid that the uppermost convolution of said coil will be below the liquid level when the receptacles are in place, but above the liquid level when the receptacles are removed, whereby to quickly cool the air' above said liquid, and to be submerged in said liquid 'when the receptacles are in said liquid.
2. A cooling device com risin a cabinet having a cover, a heat absor ing hquid withm the cabinet adapted to receive receptacles to be cooled, the surface of said liquid being exposed to incoming air when said cover is ralsed, and a refrigerating coil mounted in said liquid, said coil being completely submerged in said liquid when receptacles are therein and partly exposed above said liquid when said receptacles are removed, whereby said incoming air will be cooled by said exposed portion of said coil when a receptacle is removed.
In testimony whereof, I afiix m signature. HARRY CAN N.
