Abstract: The invention comprises an improved recoil control device comprising a bolt head and an inertia block for use in a variety of firearms. In one embodiment, the bolt head and inertia block are articulated so that the displacement of the bolt head results in a force component outside the firing axis of the barrel of the firearm. The device can be incorporated into firearms of a variety of sizes and configurations to produce recoil reduction and/or weight reduction advantages.

Abstract: A high feed ramp for use in Colt 1911 style handguns including a feed ramp on the frame (receiver) for guiding bullets into the barrel of the gun; a boiler room (barrel breech) with a small chamfered around its entire inner circumference; and an integral relief rim extension on the upper edge of the feed ramp, such that the feed ramp is extended over the bottom edge of the chamfered boiler room; wherein when the handgun is fired the bullets easily enter into the barrel and do not jam or misfire.
Abstract: A muzzleloading firearm for engaging a firing pin to discharge a primer includes a trigger plate connected between a front stock and a rear stock, with a central cavity traversing the trigger plate to support a sear and a trigger in mechanical communication with the sear. A hammer assembly is pivotally mounted to the trigger plate to rotate between a cocked position and a resting position, and includes a base extending into the central cavity. The base includes an upper arcuate surface opposite a lower locking surface having a shoulder. A hammer head member is connected to the upper arcuate surface to engage a firing pin. A rolling breechblock is pivotally attached to the plate between a retracted loading position and a firing position, and has a curved upper surface to engage the arcuate surface of the hammer assembly when moving between the loading position and the firing position to force the distal end of the sear to engage shoulder of the base.

Abstract: A muzzle-loading firearm having a barrel and a pivoting firing mechanism. The barrel has a breech plug, a pivoting junction axle. and a blocking axle, and the firing mechanism has a trigger, hammer, striker and notch. The firing mechanism is pivotally attached to the barrel at the pivoting junction axle and the blocking axle is movably aligned in the notch. When the firing mechanism is pivoted, it is guided by the blocking axle in the notch ensuring sufficient clearance between said firing mechanism for easy placement of a percussion cap.
Abstract: A semiautomatic handgun having multiple safeties includes a body made in two halves and a slide which can move lengthwise on a pair of rails. The hammer is cocked by rearward movement of the slide. The trigger, which has purely translation motion, is blocked from behind except when the user is wearing a special magnetic ring on his trigger finger. A decocker mechanism pushes the firing pin forward and slides the sear back, and prevents release of the hammer until the firing pin is blocked. The firing pin is normally blocked by a cup, which prevents the firing pin from moving forward if the gun is dropped. The cup is moved to an inactive position by a release lever only when the trigger is pulled. A safety lock, which is preferably operated by a special tool, prevents the transfer bar from moving. The firing pin block lever is locked in a downward position when the safety is activated. A hammer block bar prevents the hammer from moving when the safety is on.
Abstract: An improved auto-fire assembly for an industrial gun of 8 gauge or larger which releases the trigger of the gun in response to the breech block of the gun being fully placed in closed breeching position.The mechanism presented provides a trip arm to be contacted by the industrial gun operating lever, with the trip arm on a shaft rotatably mounted on the stop bracket limiting breech opening. The resultant simplified structure enables easy modification of existing lanyard operated guns to include autofire capability.
