Abstract: A safety mechanism for guns having an openable breech. Guns of this type have a manual lever for operating the breech locking mechanism. The invention provides a linkage between this lever and a trigger block member which prevents trigger actuation. As a result, the gun cannot be fired unless the breech is in a fully closed and locked position.

Abstract: A gun mechanism for guns embodying safety mechanism. The mechansim includes a trigger, a sear, and a hammer in operative relationship. A disconnector member is carried by the trigger and is operative to disconnect the sear from the hammer for firing. An extending member extends from the bolt carrier to a position over the trigger mechanism. A link member is positioned between the extending member and the disconnector member and is operative to hold the disconnector member in an inactive position, that is, a safe position at all times unless the said extending member is in a fully forward closed and locked position of the bolt. A bolt carrier has a limited sliding relationship with the bolt which includes a bolt locking member. The carrier undergoes an initial movement before the bolt moves which operates the link member to the safe position, after which the bolt is unlocked for movement. Positive safety is provided in that the disconnector member is held inactive unless the bolt is fully closed and locked.

Abstract: A double barrel firearm provides a selector mechanism so that either barrel can be selected to be fired first. A pair of sears is provided cooperating with hammers. The trigger can actuate either sear that has been selected by the selector mechanism for firing either barrel first. The trigger actuates a connector. The connector can actuate the selected sear. Each sear has engagement with a part of the connector whereby when a sear is actuated, it will move the connector rearwardly, the connector being biased forwardly so that it will then come into a more forward position for engagement with the second sear. Even if the barrel selected to be fired first does not fire, the second barrel will be fired on the second pull of the trigger. The connector also serves as an inertia block so it has the capability of responding to inertia to be repositioned for actuating the second sear in the event the first barrel fires in response to the first pull of the trigger.

Abstract: A bolt action hand gun, that is, pistol, having its balance point over the hand. The trigger is in a forward position on the action with an improved connection between the trigger and the sear. The improved connection is such as to prevent accidental firing when the pistol is dropped on the muzzle or butt.
