individual springs (4) each. It is designed to act as a
single spring by means of rods (3) that pass through
each set of springs and end in eyed terminals (6). The
inboard ends of the rods are bolted to clevises (2),
which are welded to an equalizing plate (1). The plate
has a threaded adjustable rod that is secured to the ship's
structure to hold the inboard ends of the spring unit.
The outboard ends of the rods are bolted to a similar
plate, which has a welded clevis outboard, through
counterbalancing spring cable. The cable (7) runs
through two sheaves and is then bolted through its
terminal to the actuator arm of the barricade stanchion,
below the point of attachment for the cylinder.
When the stanchion is lowered by the cylinder, the
sets of springs are uniformly compressed and resist the
force of the descent, and cushions its fall against the
deck. Raising the stanchion slackens the spring cable
and decompresses the spring, but this release of
compression has no appreciable effect on raising the
Stanchion latches are used to secure the stanchions
to the deck in their DOWN position. Stanchion latches
(fig. 3-43) are spring-loaded latches bolted to the
subdeck and provided with a slotted frame, designed to
allow the latch (5) to be retracted against the force of a
spring (2), and turned to lock the latch open. When the
stanchion is lowered, the latch may be engaged in a hole
provided in the stanchion, and a spring will hold the
