Abstract

Firearm bolt assemblies and firearms including the same are described. In embodiments the firearm bolt assemblies are configured to localize compressive forces applied during a transition from an initial position to a firing position to a first cam system on one side of the firearm bolt assembly, and to localize compressive forces applied during a transition from the firing position to the initial position to a second cam system another side of the firearm bolt assembly. Localizing the forces in that manner enables the use of a first cam system that is relatively robust compared to the second cam system.

IPC Classes  ?

• F41F 1/10 - Revolving-cannon guns, i.e. multibarrel guns with the barrels and their respective breeches mounted on a rotorBreech mechanisms therefor
• F41A 3/26 - Rigid bolt locks, i.e. having locking elements rigidly mounted on the bolt or bolt handle and on the barrel or breech-housing respectively the locking elements effecting a rotary movement about the barrel axis, e.g. rotating cylinder bolt locks semi-automatically or automatically operated, e.g. having a slidable bolt-carrier and a rotatable bolt
• F41A 7/08 - Drives for externally-powered guns, i.e. drives for moving the breech-block or bolt by an external force during automatic firing
• F41A 9/36 - Feed mechanisms for revolving-cannon guns

Abstract

Firearm safing assemblies and firearms including the same are disclosed. In embodiments firearm safing assemblies include a safing sector with a track surface and a receiver door track. The receiver door track may couple to a receiver of a rotatable firearm, wherein the receiver includes a bolt track and at least a portion of the receiver extends coaxially about a first axis. The safing sector is configured to be at least partially disposed within the receiver door track and to move between a safe position and an armed position. In the safe position the track surface is out of alignment with and does not form part of the bolt track, whereas in the armed position it is aligned with and forms part of the bolt track.

IPC Classes  ?

• F41F 1/10 - Revolving-cannon guns, i.e. multibarrel guns with the barrels and their respective breeches mounted on a rotorBreech mechanisms therefor
• F41A 17/32 - Multiple safeties, i.e. safeties acting on at least one element of the firing mechanism and at least one other element of the gun, e.g. the moving barrel the other element being the breech-block or bolt
• F41A 19/68 - Electric firing mechanisms for multibarrel guns
