Abstract
Abstract In a side by side refrigerator-freezer appliance, thermal leakage between the compartments is reduced by forming the liners separately for each compartment, but without the partition wall. Adjacent edges of the liners are spaced apart and desirably out-turned to form a truncated V groove. A partition wall is separately formed and foam insulated; edges of the partition are upset to form a tongue slidable along the groove whereby the partition is retained in position.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
168 words
In a combined refrigerating freezing appliance having two compartments with a common vertical partition wall, an improved means of reducing undesired thermal flow between said compartments, said means comprising: a separate liner for each compartment, each of said liners having a top, bottom, rear, and outer side wall; said liners being positioned in an encasing shell and spaced therefrom, with foam insulation material in the space between said liners and the shell, adjacent edges of said liners being spaced apart; a separate partition wall including a pair of opposed, spaced apart sheet members havng spaced apart adjacent edges, with foam insulation material between said sheet members; complimentary channel and tongue means along the spaced apart adjacent edges of said liner and said partition wall, said complimentary channel and tongue being in the form of a truncated V; whereby said partition wall maybe slidably positioned to divide said appliance into the two compartments with neither of said partition wall sheet members or portions thereof being common to both compartments.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
23 words
An appliance as defined in claim 1 wherein said truncated V channel is formed by outwardly folding adjacent portions of each said liners.
Claim 4
Dependent Claim
26 words
An appliance as defined in claim 2 wherein said truncated V channel is formed in each of the top, bottom and rear walls of said liners.
Claim 5
Dependent Claim
18 words
An appliance as defined in claim 3 wherein a resilient sealing strip positioned between said channel and tongue.
Claim 6
Dependent Claim
19 words
An appliance as defined in claim 3 wherein a resilient sealing strip is positioned between said channel and tongue.
Claim 7
Dependent Claim
50 words
An appliance as defined in claim 2 wherein said partition wall has a thickness greater than the width of said channel and shoulders are formed intermediate the planar portions of said partition wall sheet members, thereby to stiffen said partition wall and to conceal the edges of the various panels.
