- My invention relates to refrigerators and edges of the sheathings extend slightly outhas for its purpose the provision of a refrigerator which can be economically manu- :factured and to this. end the refrigerator 35. Figure 1 with the door closed;

. 5 box and door each embodiesan inner and outer sheathing and aheat insulating member between the sheathings, each of which. elements is fabricated in one piece to prov vide for their easy assembly, said assembly being completed byr connecting the inner and outer sheathings of the box and door by heat insulating mouldings specially shaped to provide an effective'seal between the box and door when`the latter is closed.

My invention further contemplates an iin- `provedv refrigerant container which is so .constructed as to provide a highly efficient and controllablev circulation o f cold air within the refrigerator,

I will describe my invention in the best form known to me at present, but it will bel l apparent that ,the same is susceptible to changes in form and proportions bythe ex ercise of only ordinarymechanical skill and without departing from vthe scope thereof as set forth in the appended claims.

In the drawings chosen `to illustrate my f invention Figure 1 is a vertical section of'a refrigerator constructed .in accordance with my invention, the refrigerant compartment'or n container being 'shown in elevation;

Figure 2, a sectionon the line 2-`2- of Figure 3, a section on the line 33"of Figure 1;

Figure 4, a sectional view of the vrefrigerant compartment or container, said view being on the line .4f-4 of Figure 3; and

Figure 5, a section. on the line 5- 5 of Figure 4.

In the embodiment of my invention illus,

j trated A indicates generally the refrigerator member 12, the latter being located between the sheathings. The sheathings 10 and 11 and the heat insulating element 12 are'each fabricated. las a one piece member of dish proved refrigerant container C whlch 1s formation `and=when nested asshown the box which I form of an outer sheathing 10,- an inner sheathing 11 and a heat insulating ward of the edge. of the insulatingelement 12. Extending between 'the sheathings 10 and llfand abutting the edge of the insulating element 12 is a frame 13 which serves as a connection between the sheathings and maintains the elements o f then-refrigerator box in` assembly as will be apparent.' The sheathings 10, 11 and heat insulatingele- I ment 12 are embraced by a'monlding 14, 60

outer sheathing 17 and xE111 inner sheathing i I 18, between which is located a heat insulating element 19, said sheathings and said element' each being fabricated in one piece. A frame 20, similar to the frame 13, extends between the sheathings 17, 18 andabutsthe edge of the heat insulating element 19, thus serving as a connection between the sheathings -and maintaining the. assembly of said sheathings andinsulating element. A

monding y21 of hea insulating material *5 covers the frame 20 and the edges of the sheathings 17 and 18. This lmoulding is provided' with a U-shaped 'formation 22 positioned to receive the formation 16 when the door is closed., 'The formation 22 car'- ries a gasket 23 which is'adapted to be com` pressed by the' formation 16 as will be ob.-

vious, to therebyprovide an effective seal for the refrigerator. From the foregoing it will be apparent that by fabricating each of the sheathings and heat insulating elements' of both the box and doorin one piece my refrigeratorlends itself t0 quantity production of an extremely economical type, .95

which economy'is further enhanced by the common type of labor which can be utilized in effecting the assembly of both the box and door.

My invention further contemplates n im ioov findiinte'dwwithin the box A preferably at one of the upper corners as shown in Figure 1. This container comprises a casing of suitable material, the front wall of..which includes a hinged door 24, said wall being provided with, openings beneath the door 4through which ice trays 25 are adapted to be inserted and removed. One side wall of the container is provided with' an opening 2G, while its bottomwall is provided with an opening 26. Pivotally mounted in and controlling the opening 26 are slats or shutters 27, 27 on the trunnions of which are fixed peripherally engaging friction disks 28, 28 whereby the manual rotation of either disk simultaneously adjust the shutters or slats 27, 27. Likewise slats 30, 30 are pivotally mounted in and control the opening 26` said slats 30, 30 being also simultaneously adjustable throughthe instrumentality of peripherally engaging disks 31,V 31 fixed on their V respective trunnions. The structure of the.

refrigerant container just described provides -an effective means for maintaining a desired circulation of air through the container as indicated by the arrows in Figure 4. At each side of the opening 26 and extending fore and aft of the casing are -in wardly directed flanges 32, 32 forming runways 33, 33 in line with the openings 25 and upon which the ice trays 25 are adapted to slide and rest. Extending inwardly from the side walls ofthe refrigerant container and over the runways 33, 33 are. bae plates the outwardly provide a seal.' A

2. A refrigerator box comprising inner and outer sheathings and insulation between the sheathings, each of the sheathings and the insulation being in the form of one piece dished member,a frame extending between the sheathings in abutting relation to the insulation member, and means securing the sheathings to the frame.

3. A refrigerator box comprising inner and outer sheathings and insulation between the sheathings, each of the sheathings and the insulation lbeing in the form of a one piece dished member, a frame extending between the sheathings in abutting relation to the insulation member, means securing the sheathings to the frame, and a heat insulatifngmoulding secured to and embracing the rame.

extending portion to thereby In testimony whereof I hereunto aix mysignature.

34, 34:which cover respectively the ice trays 25 wh'enthe latter. are upon the runways 33,33 thereby to ,prevent any/.accumulation of ldust by the contents of the trays. The

plates 34, '34 also perform the additional function of supporting an open grille 35 which latter is adapted to in turn support a suitable dry refrigerant such as solid carbon dioxide.

I claim:

y 1. In a refrigerator construction, a box having a door opening, said box comprising an inner sheathing, an outer sheathing,` a' 4heat insulating member between the sheathings, a frame secured to and extending between the sheathings and abutting the edge of the insulating member, a heat insulating moulding secured to and embracing the frame and sheathings and having an outwardly extending portion, a door controlling the opening of the box, said door comprising outer and inner sheathings, a .heat insulating member between said sheathings, a frame secured to and extending between the door sheathings, a heat insulating moulding secured to and embracing said frame and door sheathings', and having a U-shaped forma-4 tion adapted tol receive said outwardly ex'- tending portion, and a gasket carried by the U-shaped formation for engagement with
