The Youngstown Steel Door Company, Cleve
land, Ohio, a corporation of Ohio
Application August 24, 1935, Serial No. 37,717
7 Claims. (Cl. Ilm-404)
This invention relates to improvements in
house car construction.
Many thousands of house cars rendered unsuit
able for use by present day requirements are
owned by the railroads.
5
Of these cars a large
number have side wall constructions in which the
sheathing, posts and braces and side sills are of
wood. The underframes of these cars are, how
ever, of metallic construction and where these
10 underframes are still serviceable it is evident
economy to again place them in service if possible.
To this end there has been submitted to the rail
roads a scheme of conversion by means of which
modern metallic house cars are obtained. re
employing the existing satisfactory underframes
of the old wooden box cars.
' The scheme of conversion contemplates neces
sarily the attainment of modern house cars ca
pable of carrying heavy loads. y The accomplish
20 ment of this purpose presents a diñicult problem
in many instances and particularly so in the class
of wooden cars wherein the underframe embodies
center and intermediate metallic sills and in
which the conversion to metallic house cars
25 would leave the underframe without side sills.
Moreover, since the car side walls of the con
verted metallic walls function as girders they
would impress stresses upon side sills which the
old side sills could not satisfactorily carry. These
30 considerations, together with the further factor
that conversion must be met with as little varia
tion as possible in the existing members whichl
are to be reused, render the problem confronting
applicant particularly acute.
.
It is, therefore, the object of this invention to
35
overcome the obstacles above noted and to pro
vide for the conversion of cars of the character
described to metallic‘cars having the requisite
capacity and strength demanded of modern rail
40
way house cars.
'
With this object in View and others which will
become clear as the description of the invention
proceeds, this invention embodies the novel struc
ture and combination of parts hereinafter de
45 scribed and particularly pointed out and de
iined in the appended claims.
In the drawings forming part of this speclñca
tion:
'
Figure 1 is a partial elevation of a railway
50 house car embodying the invention.
~
Figure 2 is a horizontal section taken on line
2-2 of Figure 1, omitting a showing of the inter
, mediate posts and sheathing on one side of the
55
car. The floor boards are omitted from this view
in order to better show the car underframe con
struction.

Figure 3 is a vertical section taken on line 3-3
of Figure 1.
Figure 4 is a vertical section taken on line 4-4 5
of Figure 1.
.
Figure 5 is a vertical section taken on line 5-5
of Figure 1.
Referring to the drawings in which a pre
ferred embodiment 'of the invention is illustrated, 10
a railway house car designated bythe numeral III
is partially illustrated. A portion of the car side
wall construction extending from an end of the
car and partly into the door opening II is indi
cated at I2. It will be understood that the re 15
maining portion of the car side wall I2 is comple
mentary to that portion and that the car side
wall on the other side of the car is similar in
construction.
Each side wall, which is preferably constructed
as a. unit for application to the underframe of
the car hereinafter referred to, comprises door
posts, one of which is indicated at I3 and spaced
intermediate side posts I4. The door posts I3
will, of course, define the vertical boundaries of
the door opening II in each side of the car. The
door and intermediate posts are secured at their
upper portions to the depending leg I5 of a side
plate I6 which extends continuously from end
to end of the car. The side plate I6,'which is 30
Z-shaped in section, is disposed with its web I1
arranged horizontally and its inner leg I8 extend
ing upwardly and providing a means for attach
ment oi the ends of the car roof, designated gen
erally by the numeral I9. A reinforcing chan- 35
nel member 20 is secured to the upwardly ex
tending leg I8 of the side plate by means of rivets
2I passing through the web 22 of the reinforcing
member. The intermediate posts and the door
posts are secured to the reinforcing channel mem- 40
ber, this securement in the instance of the inter
mediate posts I4 being effected by means of rivets
23 passing through the ñange 24 of said posts
and the web 22 of the reinforcing channel member
as well as through a filler plate 25 disposed be- 45
tween said post flange and said web of the
channel member.
At their lower portions the
door posts are secured to a channel shaped mem
ber 26 by means of angle clips fastened to Ian
inwardly extending iiange 21 of said post as by 50
means of rivets 28 and to the web of the chan
nel member 26 by means of rivets 29. Each of the
intermediate posts is secured to the channel
member 26 by means of a bracket member 30
disposed below the lower end of the post and pro- 55
2
11,108,809
vided with flanges 3| arranged on opposite sides
of the web 32 of said post and secured thereto as
by means of rivets 33. The bracket 30 is also
secured to the web of the channel member 26 as
by means of rivets 34.
Metallic sheathing is incorporated in the side
wall constructions and extends from each door
post to the'corresponding end of the car. This
sheathing preferably embodies a plurality of
metallic sheets 35 which extend between the posts
and have their adjacent margins overlapped upon
and secured to the intermediate posts |4, as indi
cated at 36. At their upper margins the sheets
35 are secured to the depending leg |5 of the side
15 plate I6 while at their lower margins said sheets
are secured to the channel members 26 by means
of angular metallic connecting members 31.
Each member 31 is preferably Z-shaped in section
to provide an outer upstanding flange 36 riveted
20 along the lower margins of the metallic sheets, as
indicated at 39. The web 40 of the Z-shaped con
necting members extends inwardly from said up
per flange and from this web there depends a
vertical flange 4| by means of which the connect
ing member is secured to the channel member 26,
the rivets 34 being utilized to this end. It will be
apparent that the web 40 of the connecting mem
ber will be coped in order to permit the projec
tion of the flanges 3| of the attaching brackets 30
30 through said webs for the securement of said
flanges to the lower portions of the intermediate
posts.
The construction above described which, as re
ferred to, may be constructed as a unit,_ may then
35 be applied to the underframe end of a car which
is to be converted, or of a new car. This applica
tion is effected by the securement of the channel
member 26 to the ends of the cross members of
said underframe hereinafter described so that
40 the channel members are then impressed with the
function of side sills in the completed car con
struction. It will be apparent that in such con
struction the side plates, side sills and posts con
stitute girders on each side ofthe car capable of
45 carrying stresses imposed upon the underframe
of the car. Under these stresses the posts func
tion as tension members, the side plate as a com
pression member and the side sill as a tension
member.
50
,
The underframe to which the side wall con
struction is applied embodies a center sill 42 and
spaced intermediate sills 43. The center sill com
prises, briefly, spaced vertical plate members, one
of which is indicated at 44, an outer angle mem
55 ber 45 secured to the upper margin of each of
intermediate sills and the crossbearers is not
necessary and will not be given inasmuch as the
structure of these parts is well known.
In addition to the foregoing parts of the under
frame the latter comprises bolsters, one of which
is designated at 55 and end sills, one of which is
indicated at 56. These parts are of a well-known
type and need not here be described in greater
detail.
'
As hereinabove stated in the application of the
car side wall to the underframe, above referred>
to, the channel member 26 is secured to the ends
io
of the cross bearers and bolsters. This secure
ment is effected in the case of the crossbearers
by means of rivets 51 which are driven through 15
the web of the channel member 26 and through
openings existing in fianges 56 formed on the
crossbearers. Similarly, the channel member 26
is secured to the ends of the holsters 55 as by
means of rivets 59 extending through the web
of the channel member 26 and through existing
openings provided in a flange 66 of each of the
crossbearers. It will be apparent from the fore
going that in the instance of a converted ho'use
car the existing structure is utilized without modi 25
fication. The rivets 59 utilized in the securement
of the channel member 26 to the ends of the
bolsters 55 are employed to fasten to said bolsters
bracket members 6| which constitute the connect
ing and attaching brackets between the lower 30
ends of the intermediate side posts disposed op
posite the bolsters and the car underframe. Each
of the brackets 6| is supported upon a plate con
struction designated 62 extending outwardly from
the ends of the holsters 55.
35
Within the door opening, the extent of which is
defined by the door posts I3 and at the points in
alinement with these posts, the ch'annel shaped
member 26 is reinforced in such a manner as to
carry directly the stresses imposed thereon to the 40
intermediate side sills. It is apparent that within
the door opening the channel members 26 act as
beams and that they do not have the advantage
of the intermediate posts in assisting them in
carrying the stresses imposed upon said members. 45
The preferred reinforcement for the channel
members 26 in the door opening of the car side
Walls takes the form of a strut or compression
member 63, preferably channel shaped in cross
section, as indicated in Figure 1 of the drawings. 50
The strut 63 is bent at its ends so as to provide an
attaching portion 64 at its upper end, by means
of which said strut is secured to the lower in
turned flange 65 of the channel member. At its
lower end the attaching portion of the strut 63 55
is designated by the numeral 64-A and this at
taching portion is secured to the lower end of the
intermediate sill 5| as by means of rivets 66.

. With particular reference to Figures 2 and 5 compression members secured to the lower por
of the drawings it will be observed that a strap
30
member 69 connects the channel member 26 with
the intermediate sill opposite each of the inter
mediate side posts where said posts are spaced
from a cross member. These strap members con
stitute tension members. One end of each of
the strap members is riveted to the angle member
52 of the adjacent intermediate sill. For the at
35 tachment of the strap member 69 to the channel
side sill 26 the following construction is utilized.
The bracket member 3l! is provided with a hori
zontal ilange 10 which extends through an open
ing 1I formed in the web of the channel side sill.
40 'I'his ilange 10 is secured to a strap member 69 as
by means of rivets 12. It will be clear from the
foregoing construction that any tendency of the

It is clear from the foregoing description that
the invention successfully provides for the con
50 version of an old wooden sheathed car into a
modern metal sheathed car, although it is to be
understood that the instant invention may be uti
lized as readily in new car construction.
It will, thus, be-apparent from the foregoing
55 detailed description of the instant invention that
the objects thereof areiachieved by the disclosed
construction. However, it is not intended that
the invention be limited to the details of the
structure illustrated and described, it being ap
60 parent that numerous changes and modifications
of theœ precise details will be manifest to those
skilled in the art. The invention, therefore, is
not to be limited except as indicated by the claims
appended hereto.
