In the embodiment of the invention illustrated in FIG
URES 1-4 the reference numeral 10 designates a portion
of «a side wall of a railway car provided with a wide door
opening 11. The door opening is closed by means of a
main door 12 of any desired construction slidable longi
tudinally of the oar on the outside of the side wall It)
upon a track 13 and an auxiliary door 14 of any desired
construction also slidable longitudinally upon the track
13 after it has been moved laterally out of ‘the door
opening 11 in which it is seated when closed. The main
l door 12 slides to the right as viewed in FIG. 1 and-the
auxiliary door sli-des to the lett to expose the dooropening.
Any desired mechanism may be used to move the
and 26. Channel 25 faces rearwardly and receives the
member 24. Channel 26 faces forwardly and receives
the front vertical margin of the main door when the
doors are closed.
The member 24 extends along lthe lower part of chan
lngs.
The instant form of the invention also provides a mem
ber 28, preferably in the form of a casting, which is se
cured to the side sill structure 29 of the car and coop
erates with member 24 to prevent upward movement of
the front vertical margin of the auxiliary door when it
is closed. As shown in FIGURES 2, 3 and 4 of the draw
ings the front vertical margin of the auxiliary door is
reinforced by an inwardly extending Z-shaped'bar Sli
riveted to the door. The inner flange 3l of this rein
forcement is spaced laterally from the front stop 22 and
aurdliary door 14 laterally into and out of the door open
70 together therewith defines a space in which a guide cast
ing. The mechanism illustrated generally embodies a rne
chanical advantage device 15 and a pair of vertical ro
ing 32 for the sliding bolt 23 of the locking device here
inabove referred to is received. As shown more clearly
3,045,295
¿i
in FIGURE 3 of the drawings the lower portion of the
inner flange 31 of the Z-shaped reinforcing bar 30 is
removed as indicated at 33 so that it terminates above
the member 23. Thus the reinforcing bar offers no inter
ference to the lateral movement of the auxiliary door
into and out of the door opening.
The member 28 embodies a vertical liange 34. A hori
zontal flange 35 projects forwardly from ñange 34 ad
jacent to the top edge thereof. Flange 35 extends along
flange 34 and adjacent to the forward edge of the latter
turns downwardly and inwardly to provide a flange 36.
At its lower edge flange 36 is extended outwardly into
a ñange 37 under which the projection 27 lies when the
operating mcchanism forces the door laterally into the
door opening. During lateral movement of the door the
horizontal leg 58 of angle member 57 is projected through
the opening 54 provided in the plate 48. Cooperation
between the plate 4S and angle member 57 prevents up
ward movement of the auxiliary door.
Locking bolt 2‘3 is engaged with its keeper when the
door is closed and prevents outward movement of the
door. Loss of grain is prevented.
The described forms of the invention have been illus
trated in connection with the laterally movable auxiliary
door of a door combination involving such a door and a
sliding door. The invention, however, is not limited in
auxiliary door is closed as shown more clearly in FIG
URE 2.
