Abstract: A recoil dampening device incorporating a dynamic braking system and index ring. The recoil dampening device of the present invention is intended for use on weapons, especially heavy caliber weapons, having a recoiling barrel. The recoil dampening device is coaxial with the weapon's barrel and has a constant pressure brake assembly and a dynamic brake assembly. The recoiling barrel and the brake assemblies are carried within a cylindrical tube that is coaxial with the brake assemblies and the barrel. As the weapon is discharged, the force of the recoil causes the barrel to travel rearwardly thus engaging a coaxial spring. The spring engages the dynamic brake assembly and as the barrel travels rearwardly, the force applied to the dynamic brake is increased in a linear fashion, causing an increasing amount of frictional braking pressure to be applied to the inner surface of the tube and the exterior surface of the barrel.

Abstract: A firing mechanism for a breech-loaded weapon to assure safety and provide reliability of operation. A receiver is formed from a central portion that has a receptor whereby the mechanism can be assembled to the rear end of a weapon barrel, there being a pair of yoke legs extending rearward from this central portion. Each of the yoke legs have slideways to receive a closely dimensioned breech block. The breech block is moved in a reciprocating motion, when desired, by action of a lever. A shaft attached to this lever causes operation of linkage members which, in turn, move the breech block from a fully caged position within the yoke arm slideways to a shell-loading position. During this motion a hammer assembly is moved to a cocked position and an ejector removes any spent shell from the weapon.
