. It is among the objects of this invention to pro-j vide a refrigerating apparatus in which a cabinet is coordinated in an improved manner with a mechanical refrigerating system so that the sys: tem may be easily removed from; the cabinet.

It is a further object ofthis invention to mount a refrigerating system on a cabinet in an im; proved manner so that the system is efllcient in; operation and requires no exposed moving parts to produce efflcient cooling currentsoi air. v

7 Further objects and advantages of the present invention will be apparent ,from the following 1e: scription, reference being had tothe accompanye present invention isclearlyshown. 1

While the form of embodiment'of the invention as herein disclosed constitutes a preferred form, it is to be understood that other forms may be adapted, all coming within the scope of the claims which follow.

What i's-claimed is as follows:

1. A refrigerating apparatus comprising a cabinet having upstanding side walls, a refrigerating system associated with said cabinet, said system including a refrigerant translating device mounted on the upper part of said cabinet, a

' condenser and an evaporator, said condenser being mounted on one of said upstanding side walls and inducing a convection current of a portion only of the air from said condenser over said translating device.

2. A refrigerating apparatus .comprising a cabinet having upstanding side walls, a refrigeratand means for causing the convectional flow of a portion only of the air induced over said condenser to produce a cooling action on said refrigerant translating device.
