cross member 46.
In more detail, a drive shaft 63 ro
tatably mounted in a bearing 64 extends through member
46 as shown as in FIGURE 6 and is adapted to have the
pulley 62 keyed thereto in suitable manner. A motor 66
carried on a bracket 68 welded to the cross member 46 is
adapted to be coupled with the drive shaft 63 as indicated
at 70. There is one motor 66 for each of the drive shafts
63 and drive pulleys 62 as best shown in FIGURE 3. The
motor 66 may be any suitable electric motor which is re
versible so that the direction of rotation of the pulleys 62
can be changed. Motors 66 are synchronized in the usual
manner so that operation of a single control switch
means 74 mounted on the front of the cabinet will in
stantaneously start both motors in a desired direction and
drive both pulleys 62 at the same speed. If only one mo
tor 66 is used, a ?exible drive shaft may extend between ‘
the pulleys .62 so as to simultaneously drive the same.
As shown in FIGURE 2, a control box or switch means
'76 may be provided on the rear wall 16 so that a clerk
can have control of the apparatus when loading the same
through the access door 32 in the rear thereof. It will
be understood that the switch means 76 may be placed in
a parallel circuit with the switch means 74 so that either
switch unit can be .used to operate the apparatus.
An idler pulley 78 is mounted on each of the lower hori¢
zontal side frame elements 48 in vertical alignment with
the drive pulleys 62. The idler pulley 78 of one element
48 has a common aligned axis with idler pulley 78 of the
other element 48.
Endless belts 88 and 82 are trained over the pulleys 58
carried by each side frame member as shown in FIGURE
3. As shown in FIGURE 2, the endless belt 88 is trained
back and forth over the pulleys 58 carried on the vertical
standards 38 and 48 so that it provides a zigzag path with
By providing the body por
35 tion of the trays 90 of wire, there is little obstruction
to the article suspended therein such as the bottle B and
thus a more uniform cooling is provided.
Since the body portion of the trays 90 which are sus
pended between the two belts 80 and 82 hang by gravity
at all times during their movement by belts 80 and 82,
translational movement is obtained and, therefore, there
is no necessity to provide clamping means for holding
articles in the trays. In addition, the trays can support
articles of different sizes so long as the size of the article
is not great enough to interfere with a tray traveling in
an opposite direction on one of the runs 86 immediately
Referring now to FIGURES 2, 4 and 5, it will be noted
that an L-shaped plate member 100 extends beneath
each run 86 of the belts 80 and 82. The L-shaped plate
member 100 is welded at one end as shown at 102 (FIG
URE 5) to one of the vertical standards 38, 40 and
42 and extends in cantilever relationship thereto beneath
one of the runs 86 to a point adjacent one of the pulleys
S8 in the other vertical row of pulleys. The L-shaped
plate 160 provides a means to limit the sag of the belts
of a run 86 between cooperating pulleys 58 especially
when the trays 98 are carrying articles. This safety fea
ture prevents interference between oppositely moving trays
9.0 on adjacent runs .86 and insures smooth operation at
all times.
It will now be understood that the conveyor rack
36 including the endless belts 80, 82 and the trays 90
supported therebetween may be made as a unit in vary
ing sizes for existing cabinet structures.
