REFRIGERATING UNIT.

Application led August 11, 19,27. Serial No. 212,253..

The invention relates to refrigerators of the compressor type and has reference more particularly to the heat-absorbing unit in which the usual boiling action of the refrig- 5 erant takes place, said unit being provided With means to receive pans for freezing Water or other fluids.

It is the object of the invention to provide ay new and improved, exceptionally simple l0 and inexpensive and very eiiicient refrigerating unit in which ai plurality of shells which receive the fluid-freezing pans, are substan tially surrounded by the refrigerant so as to obtain maximum efliciency and at the same l5 time permit the use of a smaller quantity of'refrigerant than canv ordinarily be used, this being not only of advantage for economy in chargingthe apparatus, butin case of any leaks, as Iless of the refrigerant can run from the apparatus than if more were used.

Withthe'foregoing in View, the invention resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanyingr drawing. y l

Fig. 1 is a vertical sectional view through a refrigerating unit constructed in` accordance With my invention, showing it operatively connected with the usual float tank, to which the liquid refrigerant is pumped and from which the gas generated by the boiling of the liquid, is drawn. l

Fig. 2 is a vertical transverse sectional view on line 2 2 of'Fig. 1.-

application and While this construction will be herein specifically described,.it is to be' understood that Within the scope of the invention as claimed, variations may be made'. In the drawing above briefly described, the

numeral 3 designates an outer shell for the re-- The preferred form of construction lhas been selected for illustration in the present ply tube 13 leads to said valve, and a gas dis charge tube 14 leads from the upper portion of the tank. The float-controlled valve 11 controls the llevel of liquid in the tank 8 in 55 the usual manner, this liquid of course also fills the shell 3 through the communicating nipples, the boiling of the liquid takes placel in said shell, the gas rises through the communicating nipples 'into the upper portion of 50 the tank 8, and said gas is pumped olf through the tube 14.

The front end'of the outer shell 3 is open and is provided with an integral outstanding flange 15 to Which a removable front 'Wall 16 65 is secured by bolts 17, an appropriate gasket 18 being interposed between said flange and Wall. At suitable locations, the front Wall 16 is formed with openings 19 through which to insert theusual fluidfreezing pans (not shown). This front wall carries a plurality of inner shells 20 preferably of rectangular form, said shells having open front ends and being at said ends integrally joined to said front Wall around the openings 19, said shells 76 Abeing adapted-to receive the fluid-freezing pans. These shells are spaced from all walls of the outer shell 3 With the exception of the front Walll and they are also lspaced from each other, so that each of them may be so substantially surrounded by the refrigerant to obtain unusual efficiency, making it possible to freeze -Water, custards, etc., in a shorter period of time than is noW possible.

.. In case repairs should be necessary to one 35 I ,of the shells v2O orto the shell 3, the plate 16 may be unbolted from the shell 3,' permitting all of the shells 2O and said plate 16 to be removed as a single unit from' the shell 3, thus giving access to the interior ofshell 3 or to the 'exterior's of the shells 20, as may be required.

'Attention is again invited to the fact *hat While the preferred form of construction has been shown and specifically described,` variations may be made Within the scope of the inventionas claimed.

A refrigerating unit comprising an outer shellto contain a refrigerant, said shell being provided With externall heat-conducting:,ns, with a nipple at its top for connection with a float tank, and with aremovable front wall,

the latter being formed vwith spaced openings through which to insert fluid-freezing pans, and a pluralit of inner pan-receiving shells having open ront ends integrally joined to said front Wall and communicating With said openings, said pan-receiving shells being spaced from all other Walls of said outer shell and from each other, permitting each inner shell to be substantially surrounded by the refrigerant.

In testimony whereof I have hereunto affixed my signatnre. v
