These and other lobjects _of the inventionwill be

Will thus' be seen thatïaY substantially b'oxlsection
longitudinal' stilîener' is :formed bythe vertical

ñanges 4 and I2 and horizontal flanges -6 and
I4 of the center and side sections respectively.
The maximum strength of this box section may
be developed by closing the bottom thereof but
in practice it has been found sufficient in most
cases to attach tie plates I6 at frequent intervals
closing the bottom of the box and tying the
center and side sections together. The side seo
tions have openings cut therein to receive the
plate 44 and the center iioor section. As clearly
shown in Fig. 3 the bottom plate 44 and the
main portions of the top plate are extended be
yond the center section in order that the flanges
45 may be riveted directly to the ñanges I2 of
the outer floor sections, while the vertical flange
49 of the top plate may -abut the ends of the
“iianges 4 and 6 of the 4center floor section. It
will thus be seen that in this manner a strong

through axles or on stub axles I8 as shown.""

The ends of the stub axles support inner boxes
. or sill member with the housing backed up by
20 inserted within the box section stiffener and '
acting not only as a carl support, but also asa
' forces which are the maximum transit shocks to

stub axles and preferably these upright portions
The central iioor section is stiii'ened inter

shown. The outer ends of the stub axles sup
port outer journal boxes 22 riveted or otherwise 25 tachment thereto `by welding 4or other means.
The ends of these angles are also. welded or
attached to a load distributing structure 24'. A

portion of the load distributing structure is pref
the center floor section and will, due to the inner
erably of Z section having the lower flange 25
journal box, form a ready tie between the entire
attached to the side section 8 and with the web
extending vertically, while the top flange 26 is 30 box section stiflîeners at either side of the car,
thus in elîect continuing the stub axles across
directed inwardly for support upon the outer
the center floor section','while at the same time

preventing any sagging thereof. It will be seen
the wheel hood 28 may rest and be secured by
that the longitudinal stiffeners or sill members

provide an end and outer side adjacent each 35 together with their reinforcements carry a por
tion of the load to the stub axles, while a portion

of the load will be carried by the end walls and

32. The inner portion of the gusset is reduced 40 ner substantially every component part of the
in height and extends horizontally into contact
and attachment with the ñange I2 of the box
section stiflener and has attached thereto at the
1 upper edge an angle 33 with the one leg located
inthe planeof the ñanges I4 and 26. It'will
thus be seen that the load distributingstructure
consistsof‘ a box rlike arrangement 'formed of
a'Z land .gusset plate rigidly attached to the box
- section stiiïener and enclosing the wheel and dis
tributing the load from the side floor section to the outer journal box.

Y. The outer edges ofeach gusset 30 are attached
to angle stakes or stiffeners 34 secured to the
car structureserves to retain the lading in posi
tion and to carry the load of the ladingto the
wheels and axles. It will also be seen- that a
large capacity car has been provided with sub
stantially the entire floor area at a -low `plane
below the level of the axles and with a minimum
4of projections ~into the lading zone. Each of
the necessary projections into the lading Zone
present a smooth surface to the lading eliminat
ing pockets or other obstructions to the discharge
of lading as the car is dumped. f
Referring now to the modiiied car shown in
Figs. 6 to 9 inclusive it will be seen that the
center floor section 6I) is formed at the central
part thereof with a car haulage channel B2
adapted to receive Atherein ka car haulage lug

ofthe car. .The end walls are, of course, rigidly

connected .not only to the sideY walls, but also

the center ñoor section. The _end side floor sec

the'flanges 55 of the center'ñoor section. Suit
able cross ties ‘I3 join the lend side sections and
center iloor sections, `thus tying the box section

. 3 andz‘i the end bumper and îdraft housings. are
formed of a substantially ñat bottom plate 44
n hanged 'upwardly at its side edges- as at 45 ,(Fig.

thevcenter-se'ction, thus forming a strong stiffener
UAbetween .the box-section Aends and a convenient
Í arrangement for attachment oi the boxes 68 pre
vliously referred" to. As shown in the present
' vconstruction the'ñangef‘lìâ ofthe center section
` has been burned awayiin the area occupied by
*tl'íei floor section 15,'b-ut it is,“ofY course, obvious
Èdead.' »In-‘this car as in the car previously de~

It Will, of course,v be obvious that if desired the
’ side »ñoor section may be located at a single level
‘ 'above'the center ñoor section, in which case the
angular? `form of stiffener present'l between the
' -m‘at'tms Side' section maybe 1owered slightly 10 'aides will bev extended completely to the fend of _
the car. It may be desirable under some circum
~ and placed beneath the vflange 65'if it is so desired.
The’endfedges of the central side iioor section are
stances to’provide additional strength between

which' in turn arefrigidly connected to the .car
side wall and to the flanges 64 and ‘II- of the
center and end side sections respectively. The
lower edges of these gussets are >flanged. as at 82
vfloor section T5 may be flanged downwardly as at
H0 (Fig. 10) thence inwardly as at ll2,'thus
providing in effect a box section longitudinal
lstii’fenerthroughout the length of the car. The
to'underlie and support ‘the'inner edges of the
end side floor portions asclearly shown in Figs. 7

to such attachment the boxes H4 will be attached `

securely to the flanges 64 and 65 of the center
In this form the gussets 8,0 pre

' same position, while the flanges Ilû will. abut
the same time serving asa tie between the flanges
#such gussets and be attacheclthereto, thus in
` Yf‘lïl and 64 of the box section longitudinal stilîener.
It: will also be seen thatany loads picked upby „ ' elîect making the ñanges 1| and IIO continuous
:the `short box sectionu'stiiîeners will be trans
mitted atleast in part through the gussetl to
`throughout the length-.oi the car. >It will, of
- course, be obvious that if it is desired that the
entire side floor section be'carried atthey same
@the stiffener flanges 64 and-16 which will in turn
y ¿carry the loads to the wheels-’and axles. ¿TheV 30 level the 'construction shown `in Fig. 10 >is ex
tremely suitable and will give a completer box
