(PATENTED)
This Bunk provides the desirable combination of a Cast Steel Body with
a disappearing Chock secured by a _Tension_ Locking Bar. Practical
experiment and engineering skill have developed this Bunk to provide
"Safety First" in handling the minimum load as prescribed by the
railways. Where an adjustable Chock is not required the "Skookum" will
prove its superiority on account of its Cast Steel Body, which is
similar to our well known Hercules Cast Steel Bunk. It has also the
upward projecting flanges to prevent the shifting of the load, and the
hollow channel for the protection of the locking mechanism. This type
has been copied by designers of all modern Bunks since our first model
was introduced five years ago, and this fact is evidence of the merit
of the design.
The offset foot of the upright leg of the Chock resting upon the
sloping floor of the Bunk makes it easily held in position but
impossible to prevent its disappearing when released. Unlocking the
Chock is simple and easy and there are no sliding surfaces to wear
away. The locking bar is held by a center crank and locks on the dead
center. The recess in the heel of the Chock engages the T-head of the
locking bar and makes a positive lock. The Chock locks automatically
when brought to position. The locking bar is provided with a take-up to
provide a means of overcoming trouble incident to wear or stretch of
the parts, and always maintain a perfect adjustment.
