Affurther» feature of. construction has to do

Other features and advantages will become
more readily apparent from the following de
scription and drawings.
In the drawings, wherein like numerals are
employed to designate like parts throughout the
outstanding part thereof is the longitudinally
elongated board or plank 22 forming the >so
called endgate. This is heldin an up and out-of
the-way position by a removable locking bar 23
supported in suitable suspension hooks or clips
25 on the side walls of the truck.
The gang-plank 22 is provided on its inner or
upper side with suitable cleats 25 to facilitate
ascension and descension of stock` and cattle.
This gang-plank is detachably mounted on the
bed or bottom of the wagon, as shown more satis

the gang-plank ís provided with eye screws or
bolts cooperating with similar fixedly mounted
eyes on the adjacent end of the wagon bottom lll.

terminate in eyes, which eyes serve to slidably
accommodate the assembling and adjusting rods
3|. In connection with the rods 3|, it will be
observed that these serve primarily as hinges for
connecting the slatted side walls 34 to the gang
plank. In accomplishing this, brackets are se
cured to the lowermost slats and the brackets
have eyes 33 projecting beyond said slats, as
shown to advantage in Figure 2. The rods 3l
are therefore rigidly mounted in these eyes 33
It is thought that the description taken in con
nection with the drawings will enable a clear
understanding of the invention to be had. There
fore, a more lengthy description is thought
While the preferred embodiment of the inven

adjacent eyes on the aforesaid posts 29 and 30.

tion has been shown and described, it is to be
understood that minor changes coming Within
the field of. invention claimed may be resorted to
to maintain the eyes 33 in abutting relationship
with the eyes on said posts 29 and 30. Hence,
since the side walls 34 are of a length greater
than the gang-plank, to allow the inner ends to
if desired.
I claim:
project into the wagon when the structure is as
set up in Figure 2, it is` necessary that said side
walls should be both slidably and hingedly con
nected with the gang-plank, for when the side
walls are folded into overlapping relation, the
gang-plank is swung up to the position seen in
Figure 7, the inner ends of said side walls 34
then become substantially flush or even with the
hinge means 2S, preventing the side walls from
interfering with the closing of the gang-plank
when it serves in effect as an endgate.
Attention is now called to the numerals 35 in
Figure 5. These designate coil springs anchored
on extensions 36 at one end, the extensions being
on the bottom of the gang-plank. The opposite
ends vare anchored as at 31 on the hing-ed lower
30 end portions of the swingable side walls.
springs serve to automatically swing the sides
from the collapsed or folded position shown in
Figure 5 to the erect loading position shown in
Figure e. In this connection it will be observed
that the numerals 38 designate stop fixtures
