| New handgun configurations are enabled by a multiple cartridge magazine that includes the firing chamber for each cartridge. A hammer with a pivot pin below and between the leading and trailing edges of a chamber strikes the primer at an acute angle. A sliding trigger mechanism with cupped ball bearings in pockets facilitate sliding motion. | ||||||
| 67 | Semi-automatic pistol with a sliding barrel | US13879063 | 2011-10-06 | US08910561B2 | 2014-12-16 | Salvador Plaxats Oller |
| The pistol comprises a frame (1) containing a barrel (4) slidably mounted. The pistol further comprises a firing mechanism comprising a hammer (11) mounted so that it can pivot at the rear of the pistol, and a trigger (10) secured to an actuating arm (15) that acts on means (19) of arming the hammer (11) and retaining it in the armed position. The means for arming and retaining the hammer (11) comprise a link (19) directly connected to the hammer (11) by an articulation (20) and which is actuated via a lever (40) pivot-mounted in the frame (1). The lever has a top end actuated by the barrel as the latter moves into its forward position in order to cause the lever (40) to pivot, and a bottom end acting like a cam on the link (19) by pushing it backwards in order to rearm the hammer (11). | ||||||
| 68 | Firearm with enhanced handling by dissipating the effects of recoil and muzzle climb | US13651580 | 2012-10-15 | US08578836B2 | 2013-11-12 | Sylvio R. Lorenzut |
| A firearm having reduced recoil including a front slide connected to a rear slide by way of a slide link. Firing the firearm causes the rear slide to recoil and transfer energy, by means of the slide link, to the front slide. The front slide moving in the direction opposite the rear slide thereby reducing the recoil of the firearm. After reaching full recoil, the front and rear slides return to their resting positions. | ||||||

| The present invention is a pistol incorporating a unique reciprocating barrel which is supported for reciprocal movement in a pistol frame in a manner reminiscent of a common pistol reciprocating slide with the barrel additionally incorporating an integrated cartridge feed ramp and cartridge from magazine extracting lug combination.The present invention may also optionally employ a unique gas operated barrel delay system which delays the forward movement of the barrel. | ||||||

| A firearm apparatus and a method of firing ammunition therefrom, where the method utilizes a barrel (12) having a breech end surface (40) and immovably affixed to frame (10), a stand pressure surface (32), and a cartridge container (16) with a cartridge case (26) therein and countermass main body (18) movable in opposite directions. Gas from a deflagrating propellant moves the movable members and applies directionally opposite forces upon the breech end surface (40) and the stand pressure surface (32), which results in the force cancellation and ensures that the barrel (12) remains stable during firing. This solves the problem of the angle of departure and contributes to a high accuracy of shooting. | ||||||

| 72 | FLOATING BARREL HANDGUN METHOD OF RECOIL ELIMINATION | US10842662 | 2004-05-10 | US20050247186A1 | 2005-11-10 | Walter Lavin |
| A floating barrel gun design, a design in which a propellant gas discharge is used to counterbalance the recoil force of the gun, has been improved to include a novel automatic mechanical mechanism which allows the floating or inner barrel to be held stationary within the gun while the gas is discharged and after the discharge is complete, the barrel is released to return to its pre-actuation position. The discharge of gas is also made safer by an automatic mechanical mechanism for venting the accumulated gas, and this mechanism is activated as the projectile leaves the gun. The mechanism requires that the gas be discharged into the interior of the gun and the recoil-countering gas streams be directed toward a rearward moving breech block. The gas is discharged automatically during the firing cycle, as the firing chamber pressure falls upon the projectile exit, by venting the compressed gas through passageway nozzles which proceed through the annulus of the floating barrel and are controlled by rotatable metal plates. The discharged gas ultimately exits the gun through spaces in the outer barrel which open to the gas as the breech block moves rearward. To explain the invention, the operating of a handgun is described as the preferred embodiment. The handgun is a result of an integration of the ideas concerning a floating barrel delivery system with conventional ballistic designs. | ||||||

| A firearm (10), in particular a repeating shotgun, comprises a stock (11), a barrel (30) which is supported in axially displaceable manner relative to said stock (11) at or in a linear guide (20), a cartridge seat (31) to receive a cartridge (P) being configured in said barrel (30), further a closing system (40) fitted with a closing head (41) to close the cartridge seat (31), said closing head (41) being axially affixable in place in the barrel end (32, 33) when the firearm (10) is being closed and being traversed centrally to the barrel axis (A) by a striker pin (18), and a locking system (80) to lock the firearm (10) in its closed position. The closing system (40) is substantially configured axially symmetrically and/or rotationally symmetrically to the barrel axis (A). | ||||||
| 74 | Recoil control mechanism for a weapon | US10233275 | 2002-08-30 | US06761102B2 | 2004-07-13 | Richard Giza |
| A recoil control mechanism for a weapon which fires a projectile which is characterized by the generation of a forward counterforce to the rearward recoil simultaneously with absorption of rearward recoil force upon initiation of propoulsion of the projectile. The forward counterforce is generated by propelling a first mass forwardly upon firing the projectile and substantially simultaneously propelling a second mass rewardly for absorbing some of the recoil force. In one mechanism (10), the first mass may be the weapon's barrel (12) and the second mass its breach block (14). Expaning gases (36) from detonation of propellant in cartridge (24) enter a reaction volume (28) between the barrel (12) and breech block (14). These gases drive barrel (12) forwardly against force transmission spring (16) to impose a forward counterforce on the weapon's frame (18). Substantially simultaneously recoil from detonation of cartridge (22) together with the gasses (36) in reaction volume (28) drive breech block (14) rearwardly against force absorbing spring (20). | ||||||

| A gun comprising a frame, a barrel, and a slide. The barrel and the slide being slidably mounted to one another and to the frame for movement between a retracted position and an extended position; the barrel having a bore and having a gas port communicating with the bore for allowing gas to pass from the bore when the gun is fired; the gun having a chamber communicating with the gas port when the barrel and slide are in the retracted position and for receiving gas from the gas port when the gun is fired to cause the barrel and the slide to move from the retracted position to the extended position in a direction opposite the recoil of the gun when the gun is fired. | ||||||

| An automatic gas-operated forward recoiling combat shotgun has a reciprocally movable barrel which includes a bore and a revolving magazine which defines a circumaxially spaced series of firing chambers. In firing position one of the firing chambers is coaxially aligned with and forms a rearward extension of the bore. A cam acutated indexing mechanism sequentially positions each of the firing chambers in firing position in response to reciprocal movement of the barrel. A manually reciprocally movable foregrip functions to cock the shotgun firing mechanism and also cooperates with the trigger mechanism to release the magazine when the forearm is operated while the trigger held in a firing position. A cocking trigger enables silent cocking or uncocking of the firing mechanism. The casing of each shell forms a seal between an associated firing chamber and the barrel when the weapon is fired. | ||||||
