ABSTRACT:
A mechanical lock where a rod axially translatable through a lock housing is normally gripped by a clutch spring axially fixed to the housing, and a lever is actuated for unwinding the spring to release the rod. The lock housing is formed in a single piece by die cutting and stamping from flat sheet stock in a sequence which can be carried out in a single progressive die, to minimize the parts count and simplify assembly of the lock.
