6 Claims.
This invention relates to a refrigerator and
more especially to a refrigerator of the bottle
(Ci. 62-143)
freezing temperatures sometimes result, which is
type for refrigerating bottled beverages wherein
?n coils or other suitable type of coils are dis
5 posed along the front and rear walls of the in
terior of the refrigerator as well as along the
top of the refrigerator and wiped by the air cir
culating in the refrigerator, withsuitable doors
provided on the upper portion of the rear wall
10 of the refrigerator.
‘
It is therefore an object of this invention to
provide an elongated refrigerator having a front
wall, and a rear wall of lesser height than the
front wall, with a top disposed thereon and pro
15 jecting forwardly of the upper edge of the front

disposed not only on each side of the refrigerator
but also in the top thereof.
Some of the objects of the invention having
been stated, other objects will appear as the de- 10

It is a further object of this invention to pro
vide a refrigerator having refrigerating coils
disposed along each side thereof and adapted to

frigerator, said coils being disposed at the proper
position relative to the bottom and top of the
refrigerator to provide the proper cooling of the

order to compensate for this, the refrigerant is
