Description
Patented Sept. l5, 1924i,
rasante meer H. nomini/i., or sunmvaininniana,
REFRIGERATOR.
Application led October 11, 1923. Serial No. 667,970;
T 0 all whom t may concern.'
Be it known that I, PERGY H. DoNHAi/i, a citizen of the United States. residing at Sullivan, in the county of Sullivan and State of Indiana, have invented certain new and useful Improvements in Refrigerators; and I do declare the following to be a full,
clear, and eXact description of the invention,`
being supplemented by the accompanying drawing.
Figures l and 2 are vertical sectional views looking in different directions, each view indicating` the plane upon which the other View is cut, by means of the lines 1-1 and 2 2.
-Ii`igure 3 is a horizontal sectional view on the irregular line 3 3 yof Fig. 1.
I have shown a refrigerator casingromprising a front wall 1 having a door 2 in its lower portion. a rear wall 3, a pair of sidev walls 4t. a bottoin', and a top 6 having an ice door 7. lVliile none of these walls have been shown of insulated form, it will be understood that all of them may be of any desired heat insulating construction.
Spaced inwardly from the side walls 4. a suitable distance to provide upright air passages 8, are two curtain walls 9` said walls extending from front to back of the casing and from the top 6 of the latter to points spaced from the bottom 5. Within the upper portion of the casing, an ice chamber bottom l0 which likewise extends from front to hack of said casing, but has its ends in spaced relation with the curtain walls 9. Ice chamber end walls ll rise from the ends of the bottom l() and have their upper edges spaced downwardly from the top 6, said- Walls l1 being extended from front to back 0f the casing. Suitable air passages l2 eX- tend through the lower portions of the walls 1l, across the spaces 13 between the latter and the curtain walls 9, and vthrough said Curtain walls, for communication with the air passages 8, a suitable number of said passages being located at each end of the ice chamber. Any desired drip outlet may be rovided for the ice chamber. v
y the construction described, cold air froml the ice chamber will pass outwardly through the passages l2, then downwardly through the passages 8, and will enter the lower refrigerating compartment by turning under the curtain walls 9. The warmer air within this compartment, ascends, escapes through thefpassages 13, and thus againcoines inl contact with, 'the ice, so that it is effectively chilled. A. steady circulation of air is thus produced at opposite sides of the refrigerator, which greatly increases the efficiency of the latter.
The construction intended is exceptionally simple and inexpensive, yet it will great-ly increase the efficiency of any refrigerator. 1 The general structure disclosed may be fol-` lowed if desired, but within the scope of the invention as claimed, numerousv minor changes may be made. l i
I claim: A refrigerator comprising a casing. a pair of curtain walls spaced inwardly from two opposed side walls thereof and extending from front to back of said casing. said curtain walls also extending from the top ofthe casing to points spaced from its bottom, an ice chamber bot-tom in the upper portion of the casing extending from front to back thereof and terminating in spaced rela-tion with said curtain walls, ice chamber end and extending from front to back of the ca sing. said end walls being inwardly spaced from. said curtain walls and downwardly spaced from the casing top, andr cold air outlet passages extendingr through the lower portions of said end walls, across the space between the latter and said curtain walls, and through the latter.
In testimony whereof I have hereunto afiiXed my signature. l
PERCY H. DONHAM.
