Abstract
A multipurpose safety lock for firearms with automatic, semi-automatic or manually operated means of ejecting cartridge cases after firing is inserted in the ejection port when it is in the open position; and for firearms with a revolving cartridge-receiving cylinder, is inserted in the frame made vacant when the cylinder is in an open position. The lock comprises a body with a cylindrical assembly at the end inserted in the ejection port or the open frame, with a lock bolt extendible into the breech and barrel and lockable in that position by turning a key. While the lock bolt is in the locked condition in the breech and barrel the firearm cannot be put into firing condition and cannot be discharged.
Claims5
A removable lock for insertion into the breech of a firearm having an ejection port through which spent cartridges are ejected from the breech, said lock including a body adapted to fit within the ejection port and to extend into the breech, and means within the body for preventing removal of the body from the breech to prevent chambering of a live cartridge, said means comprising:
- a lock bolt slidably mounted in the body, and extendable forward from the body into the barrel of the firearm,
- an activating slide, slidably mounted in the body and having opposite ends protruding from the body, for moving the lock bolt,
- a pivoted lever interconnecting the bolt and the slide, and
- a lock cylinder, operable by a key, for preventing movement of the activating slide in a locked condition,
- whereby, in an unlocked condition, the activating slide can be moved with respect to the body by applying finger pressure on either end of the slide, to move the lock bolt.
