(CI. 20-22)
The invention relates to railway rolling stock
and more particularly to box car sliding doors
and associated structure, although not limited
exclusively to the same.
It is a common practice to attach a relatively
small door stop to a car side wall for the rear
edge of the door to strike when it is opened.
The railroads have considerable di?iculty in
maintaining these backstops. If the door is not
10 properly secured in the closed position, especially
if it is of the free rolling type, door movement
during switching operations, for example, will
frequently tear off or badly batter the door back
stop and sometimes damage the car walls to which
15 the stop is secured. If the stop is secured to the
door track, the battering of the door may bend
the track out of alignment. Frequently the door
itself is injured where the same. contacts with
the back stop due largely to the fact that the
” blow from the back stop is concentrated on a
small ‘area of the door edge.
In connection with extra wide doors of the
type commonly used in “automobile” cars, it is
customary to provide an auxiliary door in addi
tion to the ordinary door, the auxiliary door
having a post mounted thereon which may be
locked to the car'framing when the auxiliary
door is in closed position. This auxiliary door
post then becomes the front door post for the
ordinary door which may be'shut to close the
remainder of the door opening. When the
auxiliary door is opened, the objectionable fea
tures referred to in the preceding paragraph are
not only present but are likely to be accentuated
35 because of the increased weight of the door due
to its carrying the auxiliary post. Frequently
the auxiliary post locking mechanism is so
located that when the auxiliary door is opened
the mechanism is positioned to be injured by
40 the auxiliary door rear post on the body framing
if the door stops referred to fail to function as
intended. Also such location of the auxiliary
door post mechanism tends to reduce the eifective
length of the door opening which can be obtained.
One object of the present invention is to pro
45
vide a door and stop arrangement which will
avoid the above mentioned difficulties. Brie?y,
this object is attained by utilizing the body post
at the rear of. the door opening as a stop and pro
viding a member on the door for engaging the
same to limit the movement of the door.
In the usual car construction, the door unit,
not be exceeded because of clearance limitations,
the inside width of the car is reduced by the
thickness of the door unit and the thickness of
the post and sometimes the sheathing thereon.
It is another object of the present invention to
so form the door post and door body that they
overlap each other transversely of the car, there
by making it possible to increase the inside width
of the car.
Another object of the invention is to provide 10
coacting door and post main elements of sub
stantial thickness which will cooperate to form
a secure spark and weather seal.
It is further
desired to maintain the maximum door opening
irrespective of door and post parts provided for 15
the general purposes mentioned above.
An additional object of the invention is to pro
vide a novel mounting of the latching mechanism
for an auxiliary door post so that the same will
be protected from the auxiliary door rear post 20
and from shifting lading or other objects mov
able relative to the door and likely to injure the
latching mechanism in its usual exposed location.
Another object is the provision of an improved
latching device having a limited number of parts 25
and serving to lock the post at top and bottom
independently but in which the operation of un
locking one latch will also unlock the other latch.
Other incidental objects will be referred to in
the following description of the structure shown 30
on the accompanying drawings, in which
Figure 1 is a vertical transverse section through '
the side sill, ?oor and side plate of a car at the
door opening and showing the front edge of an

to Figure 5 but illustrating modi?ed forms of
the invention.
Figures 1 to 3 inclusive include the upper por
whether single or auxiliary door, including its . tion of a car side sill channel I, a car ?oor 2, a
front and rear edging members, overlies the door door track Z-bar 3, a threshold plate 4, a side

The left hand post comprises a similar angle I60,
plate lBb and ?ller I60. The wall outer sheet I‘!
and the inner sheeting ii! are of ordinary con
struction and are secured to the framing in the
door past and is disposed so as to abut against
offset “id of the main post when the auxiliary
door is npened, as indicated in dotted lines, there
by transmitting the blow of the door directly to
the door post throughout its. length and through
the latter to the car framing. This eliminates
the necessity of providing a door stop on the side

is bent to parallel the car side and terminates
in an offset ?ange l5d which projects into the
space between the inner and outer faces of the
25 door body. When the door is closed, as indicated
in full lines in Figure 3, the rear edge of ?ange
15a’. is spaced from the web of the Z-b'ar 9 and a
plate 2| secured to Z-bar 9 overlaps the inner
face of ?ange l5d to form a sliding and yielding
30 contact of greater or less extent depending upon
variations in the manufacture of the door and
post and wall structure. Irrespective of such
variations, the contact will be sufficient to insure
a seal against weather, sparks, dirt, etc., and
35 without limiting the closing movement of the
door.
>
When the door is opened, as indicated in dotted
lines in Figure 3, the forward edging I0 strikes
the offset ?ange lid and the latter serves as a
40
stop for the door extending substantially
throughout theheight of the latter and trans
mitting the blow from the door directly through
the remainder of the post structure and through
the latter to the car‘ sill and plate. This elimi
45 nates the necessity of providing the usual car
stops with possible damage to the car wall or
door structure due to the bumping of such stops
by the sliding door or to the failure of such stops
altogether. It will be noted that the construc
50 tion described does not reduce the effective width
of the main door opening as the front edging I0
moves completely to the rear of the door open
ing as determined by plate lib.
,
The overlapping of the door and post struc
55 ture, transversely of the car, makes it possible to
reduce the over all distance, from the inside of
the car to the outside of the door, below the mini
mum which could exist if similar post and door
dimensions were used with the door framing over
60 lying the outer face of the post in the usual man
ner. Hence, the inside width of the car may be
increased proportionately.
'
The above described construction and func
tion of the right hand’post l5 and associated
65 main door structure applies also to the left hand
door post I6 and the associated auxiliary door
structure.
,
21 which ?ts into a socket in a stop and latching
casting 28 seated in the car ?oor. A casting 29 in
the auxiliary door post guides the-lower por
tion of the latching shaft. Casting 29 also forms
a housing for and journals the post supporting
roller 2|.
When the door is moved to closed position, the
lower end of shaft 20 will ride over the threshold
plate 4 until the socket casting 28 is reached,
when it will automatically drop into position,
being supported by the shoulder S on the casting
29 and by the engagement of its upper offset
portion 2011 with the ledge 26a on casting 26.
At the same time the forward end of hook 24 35
will ride over the upper outer edge of casting
26 and automatically drop into position. When
the door is to be opened, the latching shaft 20
may be dislodged by the handle 30. This‘ will free
the interengaging elements at. the ?oor and at 40
the same time dislodge hook 24 to release the
upper end of the post.
'
This construction provides independent latch
ing of the upper and lower ends of the post al
though retainlng the desirable feature of a single 45
operation for unlatching both ends of the post
when the door is to be opened. The construction
described above provides a simple, economical
and effective arrangement of door and post struc
ture for extra wide openings in the car walls and
possesses the advantages indicated by the state
ment of objects at the beginning of the speci?ca
tion. However, many of the desirable features
may be embodied in a single door construction
as illustrated on the other drawings, and the post 55
and door construction may be otherwise modi
?ed.
In Figures 4 to 6 the right hand door post 40
corresponds to post l5 previously described but
the cooperating rear edging of the door consists
of an angle iron 4| and a supplementary sealing
element 42. The door panel sheets 43 mount a
rear plate 44 which cooperates with element 42
to yieldingly receive the ?ange 400 of the post
plate 40a thus forming a sealing structure which 65
may be more desirable.
The front or left hand
The front edging ll of the auxiliary door 8 is _ post 46 includes a plate 46a terminating in a.
provided with a stop plate between Z-bar ?ange pocket 46b facing towards the door opening and
70 and the U-plate I911. The outer o?’set ?ange 22 adapted to receive the ?ange of the door front 70
on this stop plate cooperates with the auxiliary edging 41. A front reinforcing plate 48 extends
post plate I911 to form a pocket for receiving and from the door sheets 43 to the outer ?ange of
stopping the forward edging III of the main door the front edging 41 and when the door is opened,

Figure 5 illustrates the application of a grain
door 49 to the post structures, the latter being
recessed at their inner corners to accommodate
the grain door with the inner face of the latter
?ush with the inner side wall of the car.
In the modi?cation illustrated in Figure '7, door
posts 50 and 5| are of Z-section with portions
10 of the ?anges nearest the outer face of the 'car
bent inwardly, as at 52, the wooden portions 53
of the posts being recessed at their outer oppos
ing corners to receive ?anges 52;
The door comprises ?at body panel plates 54
15 having a W-shaped front edging 55 and a Z
shaped rear edging 56 and transverse reinforce
ments 51. The inwardly extending lip 58 on the
front edging 55 projects inwardly of the inside
cent the front edge of the door so that the door
when opened may move to a position to fully clear
the door opening.

which the interengaging elements extend sub
stantially throughout the height of the door
whereby the shock of arresting the door move
ment is distributed over substantially the entire
door structure.

4. In a railway car, a wall having a door open
ing and a post at the rear of said opening, a door
having front and rear edglngs, there being a.
member on said post cooperating with said door
rear edging to form therewith a spark and 15
weather seal when the door is closed and co
operating with said front edging to limit the
opening movement of the door.
5. In a railway car, a wall having a door open
~ ing and door posts at the front and rear of said 20
20 the inturned ?ange 52 of the front post to limit
plane of the door proper so as to abut against
the closing movement of the door and to abut
against the inturned ?ange 52 of the rear post
to limit the opening movement of the door. A
spark strip 59 on the front door post 5| co
25 operates with the forward portion of edging 55
to form a front seal, and cooperating strips 60
and 6| on the rear post 50 and the rear door
edging 56 cooperate to form a rear seal. The
recesses in the outer opposing corners of the posts
permit the forward portion of edging 55 to move
beyond the limits of the door opening X so that
the latter is in no ways restricted by the inter
opening, each post including a weather seal ele
ment, a sliding door including a body panel over
lying the outer faces of said door posts' and also
including an inward-projection arranged to abut
against said elements as the door is closed or 25
gpened respectively to limit the movements of the

6. In a railway car, a wall having a door open
ing and door posts at the front and rear of said
opening, each of said posts including a Z-bar with 30
its web disposed transversely of the wall and with
the edge portion of its outer ?ange turned in
wardly from the outer face of the car wall, a
engaging door and post parts.
In Figure 8, the front door post plate 65 cor-_ sliding door including a body panel overlying at
35 responds to the plate 46a in Figure 5 but its stop least one of said outer ?anges and also including 35
forming element 65a is modi?ed to accommodate an inward projection arranged to abut against'
the transversely disposed ?ange 66 of the angle
forming part of the front door edging 61 to form
the stop element on the door.
The rear post
40 plate 68 includes an offset portion 69 acting as
a spark strip member and also as a stop for the
projecting element 66 on the front of the door
when the latter is opened.
Figure 9 illustrates a modi?cation in which the
45 spark and weather seal is rendered more effective
by utilizing strips of rubber or like packing ma
terial 10 and 1| between metal portions of the
door and post. This need not interfere with the
use of the door rear post as a door stop and the
50 provision of a stop engaging element on the door.
In this modi?cation a stop element. 12 on the rear
door post Z-bar 13 projects outwardly from the
side wall into the general plane of the door'fram
ing so as to be engaged by the plate 14 corre
55 sponding to the plate 48 previously described.

struction may be made without departing from
the spirit of the invention and I contemplate the
exclusive use of those variations which come
within the scope of my claims.
