rigidly retain upper end 19 of rod 11 substantially at right
angles to shelf 20.
It may be seen that collars 12 and 21 may be suitably
adjusted on rod 11 to allow for varying distances between
refrigerator shelves 16 and 20.
A number of knurled nuts 26 are threadedly engaged
with rod 11 in spaced apart relationship, each nut 26
being adapted to support a smoothbore bush 27.

2 Claims. (Cl. 211-—74)
This invention rel-ates to improvements in refrigera
tors and, more particularly to improvements in storage
accessories for use in conjunction with refrigerators.
In refrigerators it is highly desirable to utilize all
available storage space in order to derive the maximum
Bushes 27 are close but sliding ?ts on threaded rod 11
and each is adapted to support an arm 28 normal to the
axis thereof.
Arms 28 may support a variety of shelf members,
those illustrated being a ring support 29 for the retention
of hemispherical type containers or conical containers
30 as shown in FIG. 2, and a ?at rectangular support
'31, suit-ably perforated to permit a ?at bottomed con
bene?t therefrom, but at the same time it is necessary that
packages and the like stored therein are readily available.
Other attempts to solve this problem have resulted in
rotatable shelves which also adjust in height, the dis
advantages thereof being the added expense during manu
facture, due to the necessity for having semidcylindrical
tainer to be stood thereon on to accommodate various
taper sided containers.
It will be noted that the height of each bush 27, and,
therefore, its arm 28 and relevant support members 29,
31 or the like, may be adjusted by the screwing of its
particular knurled nut 26 up or down rod 11. At the
walls and also the shelves must be rotated in order to
raise or lower them.
Furthermore, with these and with conventional refrig
erators there remains a problem of retaining a number
of bowls, dishes and the like of various shapes and sizes
which do not readily lend themselves to stacking and
which may also be somewhat unstable. These conditions

The embodiments of this invention in which an exclu
sive property or privilege is claimed are de?ned as
1. A refrigerator shelf accessory including vertical rod

washers and nut means assembled on said rod means;
said upper washer being assembled between said stop
member and the upper surface of said shelf; said lower
washer being ‘co-operable with the undersurface of said
These ‘and other objects and features of this invention
will become apparent when taken in conjunction with 50 shelf and said out means being threadedly assembled to
the accompanying drawings in which:

Collar 12 provides a stop member for a large, plain 60 second shelf in said refrigerator for the support of said
washer 14 adapted to rest on the bars 15 of a refrigerator
shelf 16. Rod 11 is of a sufficiently small diameter to

support for one of said bushes; at least one arm extending
radially outwardly from each of said bushes; each of
said arms terminating a container support member, an
upper collar threaded‘ly attached to the upper end of
said rod and washer; and Wing nut means co-operable
