My invention relates to railway freight cars and
more particularly to the wall structure for open
top railway cars, such as hopper and gondola
cars, though the construction is adaptable for
other parts of conventional railway freight cars,
such as end walls, doors and separate panels.
Railway freight cars are generally designed so
that the‘side walls are girders or trusses to carry
part of the weight of the lading and the car itself
to the body bolsters which transmit such load to
the trucks. Such walls also, of course, retain the
load in the car.‘ Since the outside width of any
car is limited by the dimensions of tunnels and
projections adjacent the track; and the pay-load
is limited to the cubical capacity of the car, it is
extremely desirable to so design the walls of the
2
the free and ready discharge of the lading. .rEven
rivet heads are objectionable. It is important,
therefore, that the portions of the car wall adja
cent to or forming part of ‘the top and bottom
chords. respectively, are sloped to eliminate pock
ets which wouldretain partsof certain ladings
(such as sand, chats or ?ne coal).- It ‘is also im_
portant that the upper sloping element be as ‘near
the tend the side wall as possiblevand that the
sloping element‘ of the bottom chord be as near
the bottom of the interior of the car ‘as possible
because the further these two elements are apart
the greater the cubical capacity of the car will be.
The entire wall being shaped from flat sheet
metal plates, bent, pressed or otherwise formed
Without the necessity of heating, provides the
car so that the space, otherwise occupied by the
most economical way of constructing the car
wall, which is another important object of the
wall itself, is available for lading and thereby
the cubical capacity of the car is increasedwith—
Other objects and advantages of the inven

bolster at one end to that at the other end, is
disposed outside of the car posts, and thereby, is,
infeffect, one continuous outwardly bulged panel, .
a?ording the maximum possible inside width of
car, and this without decreasing the strength of
such'car wall, which is another object of my pres
ent invention.
"
Another object of the invention'is to form the ‘
wall posts which extend within the ladin‘g com
partment of a single web of relatively thin ma
terial to thereby reduce the carrying capacity of
the car the minimum amount and to assure a
complete discharge of the load when the hopper 4.0
doors are opened or when the car is turned up
side down for unloading.
As stated before, the side Wall of a hopper or
gondola railway car is a girder between the car
bolstersv and as girders comprise top chords, bot
tom chords, web plates and web platev stilfene'rs.
The side walls are also load retaining means in
which some of the stiffeners function as posts or
stakes. Such cars are sometimes unloaded by
opening the doors in the‘hoppers which areposi- ‘.
tione'd between the center sills ‘and side sills of
the ‘car and other times are unloaded by turning
the car almost upside down in a dumping ma~
chine. In either event it is imperative that there
be no obstruction within the car to interfere with.
