ABSTRACT:
A mortise-type deadlock for hingedly-mounted doors and windows where a locking block engages the lock tongue in the extended position. A pivotally-mounted stop lever on the locking block engages an abutment in the lock body to prevent the locking block being shaken free of the lock tongue. The lock tongue may be reversible and may be removed from the lock body by operating a stop member operable from the exterior of the lock body.
