This invention relates to refrigerator cars of
the kind wherein the hatchways in the roof are
de?ned by hatch frames that are supported by
a framework that is sustained by the side plates
5 of the car. The principal object of the present
invention is to utilize the hatch frames for sup
porting overhead ice bunkers beneath the roof of
the car, to provide for the ready removal and
replacement of such bunkers without disturbing
10 the carlines. hatch frames, roof sheets or roof
insulation, and to provide for simplicity and econ-_
omy of construction and compactness of de
sign. The invention consists in the construction,
combinations and arrangements of parts here
inafter described and claimed.
In the accompanying drawings, which form
part of this speci?cation and wherein like symbols
refer to like parts wherever they occur,

openings arranged one on each side of the ridge
and provided with rigid hatch frames A for ad
mitting ice or other cooling medium to overhead
bunkers B located beneath said sheets. Located
between each hatch sheet and‘ the bunkers lo
cated therebelow is a framework comprising a
pair of spaced parallel carline members l2 that
extend from side plate to side plate with their 10
ends suitably secured thereto and .themselves
connected by pairs of cross-frame members l3
that cooperate with said carline members to de
?ne openings beneathithe respective hatchway
openings in said hatch sheet.
Said carline mem
bers and cross-members preferably comprise
oblique metal angles arranged with their sides
converging downwardly.
As shown in the drawings, each hatch frame
comprises a metal frame having a relatively 20

side walls that terminate at the top of saidframe
in an inwardly extending ?ange ii that con
stitutes a seat for a hatch cover (not shown).
The narrow lower portion l5 of said frame has
downwardly converging side walls that conform
to the downwardly converging sides of the car
line members and cross-members and form a seat
for a tapered hatch plug (not shown).
The 35

Said roof sheets are provided along their
adjacent margins with upstanding ?anges 5 that

the hatch sheet is preferably provided around
the hatch opening therein with an upstanding 40
?ange l9 that is secured to the exterior side face
of the wide upper portion H of said hatch frame
by a weld ‘JD/added continuously to the top edge
of said ?ange.
As shown in the drawings,

of the hatch frame A extends below the support

the top and bottom edges of said angles. The
?ange 2| extends outwardly substantially flush
with the lower edge of the hatch frame and is 55
perforated to receive bolts 24 for suspending the
voverhead bunkers B therefrom. These overhead
bunkers are preferably arranged in alinement
opposite ends in communication with said hatch
frames, and bolts for detachably seeming said
bunker to the outstanding ?anges of the respec
sides of the ridge, being spaced apart at the ridge
tive hatch frame around the top openings in said‘
and the bunkers on the same side of the ridge

being spaced apart at their adjacent ends. Each
bunker preferably extends continuously between
adjacent hatchways with its ends located below
10 and provided with top openings that register with
car on opposite sides of the ridge, hatch frames
for the respective hatchways, and bunkers lo
cated beneath said roof and extending longi 10
tudinally thereof on opposite sides of the ridge,
the lower ends of the respective hatch frames.
These openings are defined by a frame 25 of metal
the bunkers on each side of the ridge extending
between and in communication with and sus
tained by two adjacent hatch frames on said side
of said ridge.
3. A refrigerator car roof having a plurality
angles disposed with one ?ange down and the
other facing inwardly and secured ?atwise to the
15 underside of the hatch frame ?anges 2| by the
bolts 2i. The bunkers are provided with sheet
metal top, bottom and side walls and are rein
forced at their corners by other angle irons 26.
If desired, the metal walls of the bunker may be
20 stiffened and strengthened by corrugations or
other reinforcing-members (not shown).
The roof is provided above the bunkers with
a relatively rigid insulating board lining or cell-'
ing 21 that is sustained by wooden nailing strips
25 28 secured in the angles of the carline members
and also by supporting strips 29 and 30 along
the sides and ends, respectively, of the car. The
space between the ceiling and the roof sheets
of hatchways spaced apart longitudinally of the
car on opposite sides of the ridge with the hatch
ways on one side of the ridge disposed opposite
the hatchways on the other side thereof, hatch 20
frames for the respective hatchways, bunkers
located beneath said roof and extending longi
tudinally thereof on opposite sides of the ridge,
the bunkers on each side of the ridge extending
between and in communication with and sus 25
tained by two adjacent hatch frames on said
side of said ridge, and a plurality of frames ex
tending transversely of the car from side to side
thereof above the level of said bunkers, said
is ?lled with a suitable ?brous insulation 34.
The hereinbefore described construction has
several advantages. The bunkers are suspended
from the hatch frames independently and with
out the aid of the roof sheets.
The bunkers may
be readily removed and replaced without disturb
35 ing the hatch frame, the hatch frame support
ing framework, the roof sheets or the roof in
sulation, access being had to the securing bolts
of said bunkers through the hatchways. Each
bunker may be made as long as desired and may
be provided with as many hatchways as are nec
essary to insure uniform loading of the bunker.
By arranging the hatch frame supporting frame
work above the bunkers in the space provided
for the roof insulation, the headroom of the car
may be increased without increasing the outside
height thereof.
What I claim is:
1. A refrigerator car roof having a plurality of
hatch frames therein provided below said roof
with outstanding flanges, a bunker located be
neath said roof and having top openings in its
frames being spaced apart longitudinally of the 30
car and each frame supporting a hatch frame
on one side of the ridge and the corresponding
hatch frame on the other side thereof.
4. A refrigerator car roof having a rigid metal
hatch frame therein, a bunker located beneath 35
said roof and having an opening in its top com
municating with the lower end of said hatch
frame, and means for detachably suspending said
bunker from said lower end of said hatch frame,
said means constituting the sole supporting 40
means for said bunker.
5. A refrigerator car roof having a plurality
of rigid metal hatch frames therein, a bunker lo
cated beneath said roof and having openings in
its top communicating with the lower ends of
the respectve hatch frames, and means for de
tachably securing said bunker to said hatch
frames around the openings in the top of said
bunker, said means constituting the only sup
port for said bunker.
