These and many other objects as will appear
from the following disclosure are secure by means

This invention resides substantially in the com

greater detail in the following speci?cation.

corrugated to increase the erea thereof. Secured
to the lower edges of the outermost ?ns are a
pair of brackets 5 and F5, between which extend
and to which are secured a series of small troughs
or gutters ‘i. The brackets are of dl?erent lengths 20
so that the gutters ‘i all have an inclination to
wards the hack of the cabinet. Supported so as
to be below the discharge ends of the gutters is a
rectangular tank 3 which is mounted on the back
wall of the refrigerator.’ This ‘container is pro- 25

thereof which projects into a. waste pipe in ex
tending to the exterior of the cabinet.
