a bulkhead to form an ice chamber separate from

the lading compartment, and the object of the
invention is to improve and strengthen the bulk
head and "also to improve and strengthen the
walls of the car adjacent the ice chamber and
at the same time .to provide relatively large ver
tical fines for the circulation of the convective
air currents and at the same time obtaining a
relatively large lading compartment of the car
and ice chamber of the car.

'
Another object of the invention is to increase
15 the size of the opening below the bulkhead by
eliminating the‘; usual posts which support the
bulkhead and thereby obtain an uninterrupted
space between the bulkhead and the ?oor of the
car for air circulation.
-
Another object of the invention is to reinforce
2 O the bulkhead with a metallic'plate so formed and
positioned as to provide great strength to resist
the horizontal thrust of the lading and the weav
ing of the car and at the same‘time provide a
large ?ue area for movement of the circulating
25 air in close proximity to the cooling or heating
medium without decreasingthe cubical capacity
of either the lading compartment or ice chamber
of the car.

.
Another object of the invention is to reinforce
the end wall (and preferably also the side walls)
of the ice chamber by a metallic plate so formed
and positioned as to provide great strength to
resist the horizontal thrusts of the shifting ice'
and also the impact blows of the ice as it enters
‘’ the ice chamber and at the same time provide
a large ?ue area for the movement of the cir
40
tical corrugations and to provide apertures there-
_
in so that the spaces between the corrugations
on both sides of the plate constitute ?ues for
movement of circulating air while the corruga
tionsconstitute vertically disposed beams.

by vertical webs 49 extending between the top
and the bottom of the bulkhead; that is,'from the
upper part of the lower opening 4| to the lower
30 part of the upper opening 40. The foraminous
wall 50 forming part of the ice basket is positioned
adjacent the portions 48 of said metallic plate 46
in one of said planesiand an insulated wall 5| is
positioned adjacent the portions 41 of the plate
35 in the other of said planes. By so forming or cor
rugating a metallic reinforcing plate very strong
vertical ‘beams are provided to strengthen the
bulkhead against the inertia force of the lading
and atthe same time vertical air ?ues 53-54
40 are provided on both sides of the‘ reinforcing
plate; in other words, all of the spaces between
the vertical webs 49 constitute vertical ?ues.
The drawings show a removable insulated wall
having lips 56 thereon which engage apertures 51
45 in the bulkhead reinforcing plate. (See Fig. 3.)
The bulkhead A is primarily supported by the
strap 60 which preferably extends between the
roof sheet (I I) ?anges 6| and is held in place
by the rivets 62 which hold the roof-sheet ?anges
50 and carline cap I! together. The bulkhead may
also be partially supported by means (64) fas
tening it to the side walls E if desirable. By this,
suspended bulkhead arrangement an uninter-'
rupted space 4! between the bulkhead A and the
55 floor of the car is‘ provided for air circulation be

Fig. 7 shows the portions 90-"—9l in the spaced 30
apart planes merging into a common plane 92
thus forming terminal sloping portions which are
provided with apertures 93 for the purposes de
scribed. The portion in the common plane 92 is
‘ bent to form an attaching ?ange 94 which is pro
35
vided with apertures for bolts.
Fig. 8 shows a construction wherein the rear
portions 95 merge into the plane of the front por
tions 96 and the plate is bent to form an attach
ing ?ange 91'. The portions 96 in contact with 40
the foraminous wall are cut away to provide aper
tures or notches 98 for the purposes described.
In the drawings so far described I have shown
?at portions of the metallic plate in spaced apart
planes, but if desired, the plate may be formed in
to a plurality of corrugations of sinuous con?gu
ration, as shown in Fig. 9, which give better ?ue
effect and also increased radiating surface. Cor
rugations of sinuous con?guration, that is, where
they are more rounded, minimize fatigue of metal 50
in the bending process and also minimize skin
friction to air ?ow.
I preferably provide the upper brace I06 which
receives the forces from the bulkhead A and dis-‘
tributes them to the side wall reinforcing plates
l?l and to the end wall B. I also preferably pro
tween the ice chamber C and lading compartment

supported by a plurality of posts (about four or from the lower part of the bulkhead and trans

60 structure of the car and these posts interfere with
the free circulation of air; or in other words, out
down the area of opening between the bottom of
the bulkhead and the ?oor. In my construction
I increase the area of this opening by supporting

solely from the roof structure and the side walls
