Abstract: An automated weapon system comprising an active recoil control system, a bi-directional recoil containment and double strike prevention system and a mortar retention system. The active recoil control system uses multiple sensors in combination with a solenoid controlled multi-disc brake to adjust the weapon recoil. Using outputs from the sensors, a controller predicts and reacts to a recoiling mass performance and applies the required braking force, in order to compensate for anticipated or actual variations. Feedback from the sensors allows the active recoil control system to adjust braking during the recoil strokes and counter-recoil strokes in order to optimize the weapon operation and performance in extreme firing conditions.

Abstract: An operating system for an individual firearm, such as a rifle, comprises a carriage (14) sliding axially in the compartment of the body of the firearm, an obturator (10) associable to the barrel (2), an elastic element (16), compressible between the carriage (14) and the obturator (10). In the configuration of firearm ready to fire with the bullet in the barrel, the obturator (10) has a free compression stroke (D) for the compression of the elastic element (16) and the barrel (2) has a free firing stroke (C) in relation to the abutment (32) of the operating compartment (8).

Abstract: A customizable firearm is disclosed. The firearm can perform one or more functions, including firing a bullet, firing a less-than-lethal projectile, and/or providing light. In some cases, the firearm includes a main frame component having an inner cavity, wherein a barrel is slidably received within the cavity so as to selectively slide back and forth within the cavity. In some cases, a proximal end of the barrel comprises a bullet chamber. In such cases, the barrel fires the bullet by carrying the bullet proximally and striking it against a stationary firing pin. In other cases, a firing pin is attached to a distal end of the barrel. In such cases, the barrel discharges the firearm by moving the firing pin distally and striking a cartridge at a distal end of the main frame. In some cases, the barrel rotates between a safe and a fire alignment. Other implementations are described.

Abstract: A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.

Abstract: A mechanism embodying a shock absorber, gas spring, mechanical spring or other dampening device connected between slidably connected structural components of a firearm constitutes the basis of the firearm recoil reduction mechanism claimed in this application. The slidably connected structural components may be the firearm barrel, chamber, frame, action or stock. Discharge recoil force reduction is accomplished by connecting slidably connected structural components via a dampening device such as a gas spring/shock. As the relative motion between the slidably connected components progresses, the shock absorber/dampening device is activated resulting in energy adsorption, dispersion of the recoil over a longer time period, and attenuation of the total recoil force. The net recoil force is reduced as a result of the device.

Abstract: A weapon for firing a projectile is provided that includes a receiver within which is disposed a loading mechanism for loading and unloading the weapon. A feed system supplies the loading mechanism with ammunition and a firing mechanism releases the loading mechanism for loading and firing the projectile. A barrel is rotatively secured to the receiver and preferably includes a rifled bore that imparts a gyroscopic spin on the projectile and a rotational force on the barrel causing the barrel to rotate as the projectile is fired. In a preferred embodiment, the barrel is provided with a plurality of blades that capture air and generate airflow across the weapon and barrel to cool the barrel.

Abstract: A contained Davis gun system enables misfire and hang-fire handling for fire out of battery (also known as soft recoil). The gun system decreases structural dynamic activity of the gun barrel during launch with resulting increases in system accuracy. The gun system further presents synergistic advantages when combined with a conventional recoil system in a double recoil design. The gun system includes a non-recoiling barrel and a recoil system engineered to contain a recoiling inertial breechblock capable of translating within the gun barrel. The recoil system includes a brake and a spring secured to a mount fixture. The breechblock enables the loading of the propellant and the projectile within the barrel, and further enables pressure to be contained within the barrel during firing. The recoil system applies a load to the breechblock, which is a function of the breechblock position and its velocity within the barrel.

Abstract: A conversion kit for a recoil-operating automatic pistol to convert it to direct blow-back operation utilizes a two piece barrel having chamber and muzzle portions that may be threaded together. The chamber portion is first installed on the receiver by insertion through the injection port, and the muzzle-piece is then threaded to the chamber-piece to complete the assembly of the barrel.

Abstract: An automatic projectile firing weapon and a related method for absorbing the recoil force of an automatic projectile firing weapon are disclosed. The weapon includes a barrel assembly that is slidably mounted in a receiver, biased by an operating spring, and engageable with a main sear. A gas operated bolt assembly is slidably mounted within the barrel assembly and is driven by a bolt spring. A trigger is provided to release the main sear and allow the operating spring to move the barrel assembly forwardly in the receiver. There is further provided a buffer connected between the receiver and the barrel assembly to dampen the velocity of the barrel assembly to ensure the barrel assembly is moving at a predetermined maximum velocity when a round is fired at a predetermined firing position. The recoil energy from the fired round is absorbed mainly by the forward motion of the barrel assembly and in part by the operating spring and buffer.

Abstract: A barrel positioning spring moves a barrel in a blow-back operating pistol earwardly when the slide recoils in order to position the chamber on the barrel to receive a further cartridge with the return of the slide. This spring in a Colt(.TM.) .45 caliber pistol may be seated on the recoil spring guide rod present beneath the barrel. A removable loading ramp extension is fitted to the frame in the space between the chamber end and the next cartridge to receive such cartridge as it is being chambered by the returning slide.

Abstract: The present invention relates to a personal firearm system characterized by the fact that it comprises at least two launch barrels (300, 500) and damper means (400) associated with at least a main barrel (300) and adapted to limit the recoil force generated thereby on firing.

Abstract: An automatic pistol adapted to repetitively fire blank ammunition includes a frame, a barrel unit supported by the frame and a slide unit reciprocally mounted on the frame between the forward and rear position. The barrel unit and/or frame incorporate structure which enables the pistol to operate in a highly reliable, repetitive manner without visible alteration to the pistol. A method for forming a blank firing pistol is also disclosed.

Abstract: A recoil counter-vectoring gun (10) is shown having a gun barrel assembly (14, 16, 20) slidably mounted on a frame (12). A counterweight assembly (26) is also slidably mounted on the frame (12) and is shifted forwardly by rearward recoil of the gun barrel assembly (14, 16, 20) by means of cables (38, 40) and pulleys (28A, 28B and 36A, 36B) to move forward substantially twice the distance that the gun barrel assembly recoils rearwardly. The counterweight assembly (26) preferably includes at least one throwweight (58) which is shifted from a rearward to a forward position along a declining path as the counterweight assembly reaches its forwardmost position on the frame (12). The counterweight assembly (26) is automatically returned by springs (52) and the throwweights (58) are reset and cocked by return of the counterweight assembly (26).

Abstract: The invention relates to bearing means for a gun barrel (3) mounted in the breech casing of a weapon in which the breech casing comprises a sleeve member (2) enclosing a rear part of the gun barrel (3). The bearing means comprises a cylindrical sleeve (10) positioned between said breech casing sleeve member (2) and the adjoining external gun barrel surface. The sleeve (10) is provided with a spring part which consists of a plurality of finger springs (17) distributed about the peripheral surface of the gun barrel and engaging by the force of spring an enlarged cylindrical part (7) of the external gun barrel surface. This enlarged, cylindrical part (7) has such a length (d) in the longitudinal direction of the gun barrel that the finger springs (17) are engaged to said part (7) during the first phase of the recoil during which the shell, projectile or the like has not yet left the bore of the barrel (3).

Abstract: A gun is provided having an operating mechanism and an energy storage system which receives and stores energy from the gun housing during the recoil of the gun and which subsequently transfers said stored energy to said operating mechanism during each gun cycle.

Abstract: In an automatic shoulder arm designed as a gas operated weapon, especially an automatic rifle, the entire, fully operable weapon system, comprising the barrel, the bolt system, the gas operated action, the recoil spring arrangement, the cartridge feeding mechanism and a portion of the trigger mechanism, is slidably mounted in a receiver designed as a stock. During automatic fire, the weapon system is not returned to its initial position after every shot, but performs a recoil movement during a plurality of shots before it reaches a rear end position, which it maintains until the automatic fire is interrupted. The recoil movement can be utilized for controlling bursts of varying duration and cadence.

Abstract: A gun is provided having an operating mechanism which receives and stores energy from the gun housing during the recoil of the gun and which subsequently utilizes the stored energy in two distinct phases during the counter-recoil of the gun.
