Application July 10', 1936, Serial No. 90,017
16 Claims. (01. 20-—78)
This invention relates to improvements in floor
racks for refrigerator cars, and more particu
larly to floor racks which are readily removable.
One object of the invention is to provide floor
5 racks for railway cars of the refrigerator type
which may be completely removed from the car
when desired to convert the same for use for
lading which does not require elevation from
the floor, and which may be quickly and easily
1.’) replaced in position within the car to again
restore the car to its original condition.
A more speci?c object of the invention is to
provide a removable ?oor rack of the character
described in the preceding paragraph comprising
15 sections which are hinged so that they may be
swung, out of the way, to a vertical position
against the side walls of the car, wherein the
rack sections are provided with hinge members,
permanently attached thereto and securely but
3,1, removably anchored to the walls of the car,
whereby the rack sections may be quickly and
easily detached and bodily removed from the car
to convert the car for service which does not
._~,-,
require elevation of the lading from the ?oor.
Other objects of the invention will more clearly
appear from the description and claims herein~
after following.
In the drawings forming a part of this speci
?cation, Figure 1 is a horizontal sectional view
39 of one end portion of a refrigerator car illus
trating my improved rack structure in connec
tion therewith. Figure 2 is a top plan view, on
an enlarged scale, of a portion of my improved
rack structure illustrating a certain detachable
hinge member and showing part of the wall struc
ture of the car in horizontal section, the section
corresponding substantially to the line 2—2 of
Figure 3. Figure 3 is a vertical sectional View,
corresponding substantially to the line 3—3 of
40 Figures 1 and 2. Figure 4 is a transverse ver
tical sectional View, corresponding substantially
to the line 4-4 of Figure 3. Figure 5 is a top
plan view, on an enlarged scale, of another por
tion of my improved rack structure, illustrating
4.3 a certain supporting hinge member and showing
part of the wall structure of the car in hori
zontal section, the section corresponding substan
tially to the line 5—5 in Figure 6. Figure 6 is
a vertical sectional view, corresponding substan
50 tially to the line 6-6 of Figures 1 and 5. Figure
said View being on an enlarged scale, and illus
trating the angle bar and connected hinge mem
bers detached from the other parts of the rack
structure. Figure 9 is an enlarged plan view of
a portion of the bar shown in Figure 8. Figure 5
10 is a vertical sectional view, corresponding to
the line Ill-10 of Figure 9. Figure 11 is a view
similar to Figure 3, illustrating another embodi
ment of the invention. Figure 12 is a vertical
sectional view, corresponding substantially to the 10
line l2—l2 of Figure 11.
In said drawings, A indicates one end portion
of a refrigerator car body provided with the
usual insulated walls, ?oor, and roof, the side
walls of the car being indicated by 20—2?, the 15
end wall by 2|, and the ?oor by 22. One of
the bulkheads or transverse partitions which
separates the ice compartment at the end of
the car from the remainder of the car is desig
nated by 23. As well understood by those skilled
in this art, two such bulkheads are provided in
each car, one at each end thereof, and the space
between said bulkheads serves to accommodate
the lading. When the car is used for lading
requiring elevation from the ?oor, the entire floor
space between said bulkheads is covered by a floor
rack structure. It is the common practice to
employ a floor rack structure composed of a
plurality of separate sections, comprising two
duplicate sets, the sets being divided lengthwise
of the car and each set being divided trans
versely of the car into sections.
My improved ?oor rack structure, as shown
vmost clearly in Figure 1, comprises a plurality
of similar sections 24-44, two of which are 35
shown in full in Figure l, and two adjacent sec
tions of which are shown broken away. The
sections 24 are arranged in sets at opposite sides
of the center line of the car and cover the entire
floor area of the car which is available for lad
ing. As will be understood, each complete set
may be composed of any desired number of indi
vidual sections.
Eachsection 24 of my improved ?oor rack
structure comprises spaced transverse slats
25—25 secured to laterally spaced, longitudinally
extending, supporting beams or stringers 26—26.
sponding substantially to the line 1-? of Fig
Each section 24 thus forms a unit which is bodily
removable from the car.
Referring ?rst to the embodiment of the inven
tion illustrated in Figures 1 to 8 inclusive, each
floor rack section 24 is provided with a plurality
ure 3, Figure 8 is _a top plan view of a certain
of hinges 2T, 21, and 28. The hinges 21, 21, and
connecting angle bar shown in Figure 1, for the
28 of the sections of the ?oor rack serve to sup
port said sections in such a manner that the same 55

may be swung upwardly to vertical position
the hinge member 30 of the hinge 21 to the side
against the side walls of the car, and any well
known means may be provided for holding the
same in the vertical position. In order to positive
ly hold the rack sections against endwise and
wall 20 of the car, as clearly illustrated in Figures
2, 3, 4, and '7 .
As shown most clearly in Figures 2 and 3, the
side wall 20 of the car is provided with a pocket

As shown most clearly in Figures 2, 3, 4, and 7, the
15 hinges 21-21 are anchored to the car wall, it will
be evident that a greater or lesser number of
slot 44 of- the plate 43 has a relatively wide upper
hinges may be provided on each rack section 24,
any desired number of which may be anchored
20
to the car wall.
The hinges 21-21 are preferably located at op
posite ends of the section 24 and the hinge 28
midway between the hinges 21-21.
The hinges 21 and 28 are of similar design ex
cept as hereinafter pointed out. Each hinge com
25 prises a pair of cooperating pivotally connected
hinge members 29 and 30 which are preferably in
the form. of castings. The hinge member 29 in
cludes a right angular base portion composed of
connected platelike sections 3| and 32 disposed at
right angles to each other, and a vertically dis
posed central web 33 formed integral with said
. plate sections 3! and 32. The web 33 has the
lower edge thereof inclined away from the plate
like section 32, as clearly shown in Figures 3 and
6. The web 33 is provided with a transverse pivot
pin-receiving opening 34 which is reenforced by
bosses 35-35 at opposite sides of the web, as
shown in dotted lines in Figures 2 and 5. The
base portion of the hinge member 29 is ?xed to the
40 floor rack section 24, the platelike section 32
thereof being in flat bearing engagement with the
outer side of the outermost stringer or beam 26
of the rack section 24, and the platelike section
3| bears on the underneath side of the projecting
45 end- of one of the slats 25 of the rack 24 and is
secured thereto by screws or similar securing ele
ments. As shown in Figure 1, the slat 25, to
which the hinge member 29 of the hinge 21 is se
cured, is preferably the second slat from the edge
50 of the rack section, while the slat 25, to which the
hinge member 29 of the hinge 28 is secured, is
located substantially centrally between the ends
of the rack section.
The hinge member 30, which cooperates with
55. the hinge member 29, includes a base portion com
prising a horizontal platelike section 36 and a
right angular vertical platelike section 31 formed
integral with the section 36. The base portion is
provided with a pair of spaced parallel transverse
webs 38-38 having upstanding hinge eye portions
39-39 thereon provided with aligned hinge pin
receiving openings. The webs 38-38 are formed
integral with the base portion of the hinge mem
ber 30 and the upstanding hinge eye portions em
65 brace the perforated portion of the web 33 of the
hinge member 29. The hinge members 29 and 30
are pivotally connected by a hinge pin 40, prefer
ably in the form of a bolt, extending through the
openings of the hinge eye portions 39-39 of the
70 hinge member 30 and the opening 34 of the hinge
member 29. The hinge plate section 31 of the
hinge member 30 of each hinge 21 is provided
with a horizontally disposed T-shaped head 4|
which projects from the rear side of said plate.

section and a relatively narrower lower section.
The wide upper section of the slot 44 is of such a
height and width as to permit easy insertion of
the wide portion of the T-head 4|, while the nar
rower lower section of said slot is restricted in 20
width to fit the neck portion of the T-head and
have the projecting side portions of said head
overhanging the plate at opposite sides of said
narrower section of the slot to thereby lock the
head against withdrawal in an outward direction.
The heads 4|-4| of the hinge sections 30-30
thus securely anchor the hinges 21-21 to the side
wall of the car when the parts are in the position
shown in Figures 2, 3, 4, and 7, thereby holding the
associated rack section securely anchored to the
car.
As shown in Figures 5 and 6, the hinges 28-28
differ from the hinges 21-21 only in that the
hinge members 30-30 of the former are not pro
vided with anchoring heads 4 |-4 |.
The hinges 21, 21, and 28 of each rack sec
tion 24 are preferably connected by a longitudi
nally extending angle bar or beam 45 comprising
a horizontally disposed base portion 45 provided
with an. upstanding integral ?ange 41. The hori w
zontal base portion underlies the bottom platelike
sections 30 and the upstanding flange 41 abuts
the rear sides of the vertical platelike sections
31 of the hinge members 30 of the hinges 21, 21,
and 20, and are secured thereto in any suitable
manner, being preferably welded as indicated in
Figures 2, 4, and 5. As shown in Figures 2 and
7, the ?ange 41 is suitably recessed to accom
modate the neck portions of the T-heads 4|-4|
of the hinge members 30-30 of the hinges 50
21-21. The bars 45 form bracing and stiifening
members for the bases 36 of the hinges 21, 21, and
28 and hold these hinge members in alignment.
The base portion 45 of each bar is provided, at
spaced intervals, with depending prongs 48-48, 55
as clearly shown in Figures 8, 9, and 10 to hold
said bars against endwise slippage. The prongs
48-48 are preferably formed by slitting the metal
and bending down the end portions of the slit
sections.

The embodiment of the invention illustrated
in Figures 11 and 12 involves a modi?ed anchor
ing means for the hinge members 21-21. As
shown in said ?gures, the hinge 21 has the head
4| of the hinge member 30 thereof provided with
a neck portion 48 which has the opposite side
faces thereof downwardly and inwardly converg
ing, thereby providing a. wedge shaped section.
The inner end faces of the laterally projecting
portions of the T-head 4| are inclined to the ver-_ 70
tical as indicated at 50-50.
The cover or an
choring plate 43, which closes the pocket 42, has
the narrower lower section of the slot 44 down
wardly tapered to correspond with the taper of
the wedge shaped neck section 49 of theT-head 75

2,106,852
‘4| so that the neck section will be wedged into the
slot to positively hold the hinge 21 against lat
eral play when the latter is anchored to the plate
43 by the head 4|, as most clearly illustrated
Cl in Figure 12. The walls of the plate 43 at op
posite sides of said narrower section of the slot
44 are thickened, the inner faces of said thick
ened portions being correspondingly inclined to
the inner end faces of the head 41 of the hinge
member 30, thereby providing wedge acting por
10
tions which wedge against the head when the lat
ter is forced down to positively lock the hinge
member 30 against movement toward and away
15
from the side wall 29‘ of the car.
When it is desired to convert the car for ser
ice for lading which does not require elevation
from the floor, the rack sections are detached
and completely removed from the car, thereby
making available the maximum lading capacity of
the car.
In detaching the different rack sec
tions, it is merely necessary to lift the outer side
portion of each rack section until the heads
4l—4l of the hinges 21-41 register with the
upper or enlarged portions of the slots 44-—44
25 of the anchoring plates 43—43 and then with
draw the heads through said openings by pull
ing the rack section away from the side
wall of the car. To replace the rack sections,
the reverse procedure is followed, the heads
members of each set being rigidly ?xed to the
car and the other member of each set being rigid
with the corresponding hinge member, one of the
anchoring members having anchoring shoulders
and the other member of said set having a head
removably engageable with said shoulders.
