due to the provision of the slots 49, the pins or securing
elements 5d can shift back and forth in the slots 49 in
order to permit the necessary or desired movement of the
upper ends of the tracks 38. In addition, the clips 58 on
the support member 53 provide a slidable support for
the upper sections 4t?, and the support member 53 is
adapted to be suspended from the top of the freight car
‘39 as for example by means of the hangers 55. The
lower ends of the tracks 33 are provided with the aper

Similarly, the other pair of tracks 39 are slidably sup
ported, and the tracks 39 have their upper sections 43
slidably supported by the brackets 59 on the support mem
ber 53. The lower vertical sections 45 of the tracks 39
are movably supported by mea-ns of apertured lugs 165
slida-bly or adjustably engaging pins 91 on base members
moving the tracks and doors so that the doors can be
brought tight up against the vertical posts 35 in order
to insure that grain or other material being hauled or
handled will not accidentally leak or spill out between
the doors and posts. After the door has been brought
tight up against the posts, a wedge element 169 is posi
86 in the same manner as described in connection with
the slidable supports for the lower ends of the tracks 3S.
ln order to adjust or move the tracks, there is provided
tioned on the stud 15@ as shown in FEGURE 4 and 25 the hand piece 156 which are arranged as shown in FIG
FIGURE 6 for example, and then manual pressure on
URE 6 for example. Thus, to move the tracks to a
the hand piece 156 can be released so that the wedge
position such as that shown in FIGURE 6 so that a door
element will prevent the door from accidentally moving
away from the posts. The wedge element 16% is adapted
to be retained in its proper position on the stud 15d by
means of an arm 161 which is pivotally connected to the
plate 146 as at 162.
As shown in FÍGURE 1, spaced apart rungs 163 are
connected to the door 6d.
Referring now to FIGURE l6 of the drawings, there is
illustrated a modilication wherein the numeral 3G' indi
60 is tight against the posts 35, the hand piece 156 is
moved in a generally clockwise direction from right to
left in FIGURE 6 and since the stud 151 is connected
to the hand piece 156, then with the inner end of the
stud 151 secured to the track section 45 or 42, it will be
seen that wtih the end 158 of the hand piece 156 bearing
against the portion 159 of the plate 146, that this manual
movement of the hand piece 156 will cause the tracks
to be moved or pulled towards the plate 146. Since the
rollers £6 of the doors 60 are arranged in engagement
with the tracks, it Will be seen that this movement of the
