providea flange II3ewhilchr'is riveted or otherwise secured upon a plurality of horizontally spaced brackets I4 which are in turn secured to the rail R, said brackets serving to space the flange I3a rearwardly from said rail R, and to support said flange and the connected portion I 2. The back edge and the front-to-rear edges of the partition I0 are uid-tightly secured to the refrigerator lining I5, the spacing of the flange I3a at the front of said partition from the rail R, however, permitting the ascent of relatively warm air from the front portion of the food chamber F into the front portion of the ice chamber I.

I Secured-.to thelowersideof therack-ZZ, I have shown shield.-y ing means 24 extending over air circulation openingsv25 `which-.are formed through the partition III. Theshielding .means 24 prevents any-water dripping -from the rack 22 directly p. throughA the openings .25; `and. ,to lprevent fwater iiowing down `the uppernsidel of-thepartition I0 .from passing` through thefopenings 25,. protectingflanges 26., are f providedV Aaround -said openings.
. The.. upwardly..flowing..relativelyA warm. .air in the-frontportion-of `thevice chamber. I, `after reaching theupperl .portion of .thischamben flows rearwardly,- vdownwardly..behindthe Aice block B`, and downwardly,A at `opposite.. sides of. the latter, said air passing through openings 2T in the bot` toms of the channels 22b and also through openings number 30 on either side of the ice rack, and also may pass behind ice cake through openings 22a and then descending through the openings 25 into the rear portion of the food chamber F. Rearward sliding of the block B against the rear wall of the refrigerator is prevented by a, vertical guard rack 28 which may be spaced from said rear wall by means of vertical spacing bars 29, the space between the rack 28 and said rear wall constituting an 'air conducting passage through which the air may descend behind the ice block. This air flows downwardly and forwardly through the openings 228L and 21 into the space between the rack 22 and the partition I0,
and while most of this air descends through the openings 25, the least chilled naturally has a tendency to short-circuit to the ascending air. It, therefore, flows forwardly through the openings I3 and is entrained with the ascending air flowing to the front portion of the ice chamber I from the corresponding portion of the food chamber F, through the passage 20 and the slot 2 I. No drippings fromthe ice blockAB can reach the portion of the plate or wall l1 in the vicinity of the slot 2l and hence it is not necessary to.y provide any means over this slot to prevent such drippings from owing therethrough into the food chamber.
By providing the novel construction shown and described or a substantial equivalent thereof,.an improved refrigerator is produced in which 'air circulation can much more freely take place than in the patent above mentioned. While the details disclosed are preferred, attention is again invited to the possibility of making variations within the scope of the invention as claimed.
I claim:
1. A refrigerator comprising a casing having a partition dividing it into an upper ice chamber and a lower food chamber, said partition having an opening through which air may descend from said ice chamber, said casing being provided with upper and lower doors into said ice and food chambers respectively and with a dividing rail between said doors, va sill for the upper door projecting rearwardly from said dividing rail, a-

3. A refrigerator comprising a casing, a partition dividing said casing into an upper ice chamber and a lower food chamber, said partition having an opening through which air may descend, said casing being provided with upper and lower doors into said ice and food chambers respectively and having a dividing rail between said doors, the front edge portion of said partition being rearwardly spaced from said dividing rail and. having an upstanding wall formed with an opening through which air may flow, the upper edge of said wall being provided with a forwardly projecting iiange which 'also is spaced rearwardly from said dividing rail, brackets upon which said flange is secured, said brackets being secured to said dividing rail, a cowl overlying said flange and extending downwardly at the rear of the aforesaid wall to prevent drip water from flowing through said opening, and a second vertical wall carrying said cowl and rising therefrom, the upper edge portion of said 4second wall being secured to said dividing rail, said second wall having an opening through' which ascending air may enter the ice chamber.
V4. A refrigerator comprising a casing, a partition dividing said casing into` an upper ice chamber and a lower -food chamber, said partition having an opening through which air may descend, said casing'being provided with upper and lower doors into said ice and food chambers respectively'and having a dividing rail between said doors, vthe 'front Y'edge portion of Ysaid partition being rearwardly spaced from said dividing rail and having an upstanding wall formed with an opening through which air may flow, the upper edge of said' wall being provided with a forwardly projecting flange which also is spaced rearwardly, from said dividing rail, brackets upon which said'flange is secured, said brackets being secured to'said dividingv rail', a cowl overlying said flange and extending downwardly at the rear of the aforesaid wall to prevent drip water from flowing through said'opening, and a second vertical'wall carrying said cowl and rising therefrom, and a sill for the upper door, said sill being secured to and projecting rearwardly from said rail, the'upper edge portion of said second wall being secured to said sill, said second wall having an opening through which ascending air may enter the ice chamber.
