Abstract: A lever action firearm having a receiver, a hammer, a lever pivotal about a fixed point, a bolt and a link which link is pivotal on both the bolt and the lever. The pivotal lever includes first surface means to engage second surface means on the hammer to cause the hammer to be cammed back during unloading. The lever, link and bolt are configured such that when they are in the fire position and are subjected to forces of firing they function as a joint lock to prevent unloading of the bolt and lever. Locking surfaces on the receiver and bolt strengthen the joint lock at the moment of firing.

The end caps have holders (48) with recesses (48C) which hold the ends of the barrel in the container. The holders preferably have an opening in the bottom wall (48D) of the recess and orifices (52) around the sidewall. To use, the barrel of the gun is mounted in the bottom end cap inside the container and cleaning fluid (102) is poured into the container. The top end cap is sealed onto the container and the cleaning rod is inserted into the container and into the inside of the barrel.

Abstract: This invention relates to a combination locking device for controlling existing safety devices on firearms or work independently as a safety on firearms. It is operable to engage and disengage either the existing safety, or act independently to block the firing mechanisms of guns. The invention includes a lock member that will limit access to a firearm's firing mechaniam. The invention is a spring loaded assembly that is totally mechanical. It has an engageable structure that when activated will render a weapon useless. The assembly can be instantly disengaged enabling the authorized user of the firearm to operate the firing mechanism.

Abstract: The present invention discloses a firearms safety system for adapting conventional handheld firearms to fire non-deadly simulated training ammunition, which system provides a series of gas relief ports and passages to prevent the successful firing of live ammunition in the firearm. The system can be advantageously utilized in modified M16 type military type rifles which have been previously adapted to fire pistol cartridges such as the 9 mm and .40 S&W calibers.

Abstract: A safety device for locking fire-arms prevents the use of a revolver by an unauthorized person. A main body of tubular configuration includes a key-core, which can be axially displaced and is arranged inside the main body. A locking element projects from a piece which contacts a spring. The spring contacts a bottom wall of the main body. An end of the locking device passes through a window in the bottom wall.
