REFRIGERATNG APPARATUS Filed NOV. 6, 1924 zatwse T l n Patented Mar. 25, 1930 UNITED STATES PATENT ori-ics HARRY B. HULL, OF DAYTON, OHIO, ASSIGNOR, BY MESNE ASSIGNMENTS, TO
` FRIGIDAIRE CORPORATION, A CORYORATION OF DELAWARE REFRIGERATING APPARATUS Application led November 6, 1924. Serial No. 748,258.
The present invention relates to refrigerating apparatus and particularly to the cooling "of a plurality of compartments, for example 'food containers suchv as ontainers for ice cream or the like.
One of the objects of the invention is to reduce the cost and facilitate the manufacture of a refrigerating apparatus.
Another object of the invention is `to prom vide a refrigerating apparatus in which a plurality of compartments are cooled .to substantially the same temperatureby individual refrigerating elements one :for each container, the elements being connected in series relation.
Other and further objects and advantages of the present invention will be apparent from the following description, reference being had .to the accompanying drawings wherein a preferred embodiment of one form of the invention is clearly shown.
In the drawings:
Fig. l is a sectional view taken on line 1-1 and 11 of Fig. 2 showing the improved refrigerating-apparatus; and
Fig. 2 is a plan view partly in elevation and partly in section, of the device shown in Fi 1.
Igteferring to the drawings,.a compressor is shown at 20 driven by a motor 21 and which is adapted to force refrigerant into a condenser 22 and thence through a pipe 23. This mechanism is supported within a cabinet 25 which also supports a motor controlling switch 26, which'is controlled in any suitable manner such as b the temperature of the device being coole or by the pressure of the refrigerant..
A refrigerator cabinet 30, which is adapted to be cooled by the mechanism within the cabinet 25, comprises an angle iron frame 31 which supports at the bottom a base 32, which carries f an insulating bottom wall 33. The side walls 34 and the end walls 35 and 36 are also constructed of insulating material.v The top of the angle-iron frame 31 carries a wooden frame 38 which is apertured to receive an insulating top wally 37. The top wall 37 rests upon the end walls 35 and 36 and side walls lo 34 and may be secured to the frame 38. A
Thesecoils areconnected in series relation by couplings 54. In order to compensate for th`e temperature rise in the coils between the valve 52 and the compressor 20, so as to cool all of the food compartments at substantially the same degree of temperature, the number of convolutions of the coils increases progressively. In this manner, although the temperature of the coil 44*iL is slightly higher than the temperature in the coil 43a and like- 1013 wise the temperature in the coil 43'L is slight- 1y higher than the refrigerant in the coil 42,
said coils 43a and 44a will maintain the temperature of the compartments 43 and 44 substantially the same as the temperature of the compartment 42.
By removing the top 39 and likewise insulating wall 37, then removing the sleeves 55, and uncoupling the coils, each container and its coil can be removed, as a unit, separately.
While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the' scope of the claims which follow.
What is claimed is as follows:
1. Refrigerating apparatus comprising in combination a plurality of compartments to be cooled, and means for refrigerating all of the compartments to substantially the same temperature including an individual refrig erating element associated with each compartment, said elements being connected in series to form a single conduit, and means for supplying refrigerant to `one end of the conduit, the refrigerating surface of the elements being increased along the series in the direction of flow of refrigerant from Vsaid supply means. t
2. Refrigerating apparatus comprising in combination a plurality oi compartments to be cooled, and means for refrigerating all of the compartments to substantially the same temperature including a single conduit formed into a plurality of coils, one coil being associated with each compartment, and means for supplying refrigerant to one end of the conduit, the number of convolutions of the coils being increased along the conduit in the direction ofiow of refrigerant fromsaid supply means.
In testimony whereof I hereto aix my signature.
HARRY B. HULL.
