Dis`ap*pear"ing,
Definition: p. pr. & vb. n. of Disappear.
Disappearing carriage (Ordnance), a carriage for heavy coast guns on
which the gun is raised above the parapet for firing and upon
discharge is lowered behind the parapet for protection. The standard
type of disappearing carriage in the coast artillery of the United
States army is the Buffington-Crozier carriage, in which the gun
trunnions are secured at the upper and after ends of a pair of heavy
levers, at the lower ends of which is attached a counterweight of
lead. The levers are pivoted at their middle points, which are, with
the top carriage, permitted restrained motion along the slightly
inclined chassis rails. The counterweight is held in place by a pawl
and ratchet. When the gun is loaded the pawl is released and the
counterweight sinks, raising the gun to the firing position above the
parapet. The recoil following the discharge returns the gun to the
loading position, the counterweight rising until the pawl engages the
ratchet.
