ABSTRACT:
The present lock assembly is to prevent rotation of a gun cylinder or similar rotatable body. The lock assembly has a housing that is slidably insertable into a chamber in the gun cylinder from the back end. An eccentric lock at the front end of the lock housing is slidably insertable through the cylinder chamber, after which it may be turned to a locking position in front of the cylinder by a key inserted into the back end of the lock housing. Within the lock housing an off-center shaft carries the eccentric lock and cooperates with a spring-biased release slide for operation by the key to turn the eccentric lock between its "unlock" and "locking" positions. A fixed projection on the back end of the lock housing is disposed outside the back end of the cylinder for engagement with the gun body to prevent the cylinder from turning.
