EFRIGERATOR FREEZING DEVICE.

Application filed June 12, 1926. Serial No. 115,687.

It is the primary object of my invention my invention consists in the arrangement,

combination and construction of the various parts of my improved device as described in the specification, claimed in my claims and shown in the accompanying drawing, in which:

The-single figure is a sectional-view of a portion of a refrigerator cabinet and of my improved device installed thereinv I have shown a portion of a refrigerator cabinet' designatedgenerally as 5 through which the pipes 6 and 7 leading from and to an expansion chamber are extended.

An expansion chamber is mounted in the compartment 8 lof the cabinet 5 and com prises two superposed sheets of metal 9 and' 10 the edges of which are -bent together and suitably sealed as at 1 1, and the faces of which are at intervals joined together as at 12 by spot-Welding or any other suitable The top plate 10 is provided with av means.

flanged opening 13 for receiving the pipe 14 leading from a conventional l'expansion valve 15 Aand refrigerant intaking pipe 7 .1

The-sheet is provided with a similar flanged opening 16 connected with the refrigerant offtake pipe 6. The plates are bent on themselves to provide a plurality of horizontal surfaces or platforms 17, 18 and 19 on which are placed a plurality of conventional ice'trays 20. The hood 21 m'ay be provided overthe expansion chamber and ice trays so as to enclose them.N A suitablefront cover for the through' to. the expansion valve 15 Aand r e-v leased by the valve 15 in a conventional maii-v ner to the bottom of theexpansion chamber through the flanged opening 13. The refrigerant will pass between the

plates

9 and 10, taking a deviouscourse as directed by the spot-Wel pipe 6 in a conventional manner as a gas.

The bending of the

sheets

9 and 10 so as to form the expansion chamber in a plurality of supporting platforms permits the use of a large number of ice trays so that la-largequantity of -ice may be frozen with the resultant -andvantage of-both a'largeice supply and a lengthening .of the non-operating period of the refrigerating mechanism.

It will be obvious that various changes s 12,. and Will pass off through .the

may be made in the arrangement, eombin'a- I tion and construction ofthe various parts of my improved device Withoutadeparting from the spirit of my invention, and it is my intention to cove'r'by my claims 'such changes 'A as may be reasonably included within the scope thereof. Y

What I claim is 1. A refrigeration device comprising superposed sheets of met-al having their edges sealed,- said sheets being spaced apart .to

vform an' expansion chamber betn'een them,

and bent to form a plurality of platforms for the reception of liquid freezing "trays 2. A refrigerator device comprising superposed sheets off metal spaced apart and hav.-

ingtheir edges sealed to form an expansion chamber between l them, said sheets being bent on themselvesto form a plurality of separated2 platforms, one above the other, for the reception of liquidfreezing trays.

3. A refrigerator device 4comprising superposed sheets of metal having their' edges sealed, saidsheetsl being spaced apart to form an expansion chamber'between them,

said sheets being bent on themselves to form a plurality of separated platforms, one above` -the other, for the receptionof liquid freezing trays and a hood enclosing certain of the `sides of said chamber to form a freezing chamber.

4. A refrigerator device comprisingsupeiposed sheets of metal spaced apart and having their opposed edges sealedV and their faces intermittenty joined together to form between the same, and inlet and outlet openingsiforA said chamber, the horizontally ex- 9. Al freezing unit for' a I mechanical retending portions of said device presenting a by toserve as shelves.

6. A refrigerator device comprising a pair substantlal area 'in a horizontal plane whereof interitting generally S-shaped sheets of metal sealed alonethelr opposed edges and generally spaced tween the same to form a relatively shallow chamber having a plurality of horizontally extending portlons adapted to serve as shelves, an opening ad- ]acent the bottom of said chamber for the introduction of refrigerant thereto, and an opening adjacent the top of said chamber for the passage of refrigerant therefrom.

7. A refrigerator device comprisingr a pair of interttin sheets of metal, each of which is reversely nt upon itself to form a plurality of relatively widely spaced horizontal ggrtions, the opposed edges of said sheets ing 'sealed and said sheets being generally spaced from each other between said edges to form a relativelyfshallow chamber between said sheets, inlet and' outlet openings for "said chamber, and a hood around said sheets in spaced relationship tov the topmost of said horizontal portions.

8. A' refrigerator device comprising super- ,posed sheets of metal having their edges sealed, said sheets being spaced apart to form an expansion chamber between them and bent to form a plurality of platforms for the reception of freezing trays, and a hood enclosing the top and sides of said sheetsl and spaced from the top thereof.

`nessuno frigeration system comprising a refrigerant expansion chamber composed of metal sheets secured together at their edges and at a point or points in their adjacent surfaces and having there-between spaces for the circulation of refrigerant, and having a portion thereof return bent in a plane removed from and substantially parallel Vto the other portion thereof, thereby forming supporting shelves, a hood member positioned upon said expansion chamber and enclosing the disconnected space between the parallel portions thereof and having openings providing access to theA helf-like portions of said expansion cham- 10. A freezing unit for a mechanical refrigeration system comprising a refrigerant expansion chamber composed of vmetal sheets secured together at their edges and at a point or points 1n their adjacent surfaces and having there-between spaces for the circulation v `ofrefrigerant, and having a portion thereof return bent in a lune removed from and substantially para lel to the other por-l tion thereof, thereby forming supporting shelves, a hood member positioned uponsaid expansion r'chamber formingA an enclosed Y s ace about one side thereof, andcnclosing t edisconnected space between the parallel portions. thereof4 and having openingsproviding access to the shelf-like portions of said expansion chamber.
