| A weapon system includes a receiver and an operating group with a barrel extension arranged to axially translate relative to the receiver. In the firing condition, the op-rod assembly and bolt assembly are driven by the drive spring such that the round is guided into the chamber and the op-rod assembly and bolt assembly are locked to the barrel extension and a forward momentum of the op-rod assembly is imparted to the operating group and the round is fired. A portion of an impulse stops the forward momentum of the operating group. In the recoil condition, the operating group is driven rearward by the remaining portion of the impulse, the gas accelerator imparts additional rearward momentum to the op-rod assembly and bolt assembly and stops rearward momentum of the barrel and barrel extension, and the op-rod assembly and the bolt assembly are stopped by the drive spring. | ||||||

| A semi-automatic rifle (10) including a recoiling barrel (24) adapted to carrry rearward the elongated bolt carrier (42) containing the bolt (45) for compressing the recoil spring (43), and a self-unlocking device (73, 76, 78) including a self-unlocking rod (76) longitudinally slidably mounted on the bolt carrier (42) normally engaging the rear face (39) of the barrel (24) in a battery position and a trip actuating device (73, 78) for thrusting the self-unlocking rod (76) forward during the early stage of recoil for separation of the bolt carrier (42) from the barrel (24) before the barrel (24) reaches the end of its recoil movement. | ||||||

| The weapon (10) includes a barrel (13) joined to a barrel yoke (21) in a receiver (14) aft of a front housing assembly (15). The recoil system includes a main recoil spring (30), a secondary spring (23), a buffer group including rods (60), springs (61) and plate (63). A slide bolt assembly (40) includes a slide (41), a bolt (42), a face (43), bolt face levers (44) and actuating pins (45), all within the receiver (50). The bolt face (43) is driven vertically by the bolt face levers (44) to receive a new found round (91), load it and remove and discharge a spent casing (90). The slide bolt assembly (40) travels forward and aft during the firing cycle. On rearward travel it is accelerated rearward by accelerator (70) until reaching the buffer group and transfers its kinetic energy to the buffer group which in turn transfers that energy to the barrel (13) and the recoil spring (30) where it is absorbed without transferring the impact loading to the weapon mount (11). | ||||||

| 18 | Weapon system with short recoil impulse averaging operating group | US13562078 | 2012-07-30 | US08919238B2 | 2014-12-30 | David Steimke; Glenn Rossier |
| A weapon system includes a receiver and an operating group with a barrel extension arranged to axially translate relative to the receiver. In the firing condition, the op-rod assembly and bolt assembly are driven by the drive spring such that the round is guided into the chamber and the op-rod assembly and bolt assembly are locked to the barrel extension and a forward momentum of the op-rod assembly is imparted to the operating group and the round is fired. A portion of an impulse stops the forward momentum of the operating group. In the recoil condition, the operating group is driven rearward by the remaining portion of the impulse, the gas accelerator imparts additional rearward momentum to the op-rod assembly and bolt assembly and stops rearward momentum of the barrel and barrel extension, and the op-rod assembly and the bolt assembly are stopped by the drive spring. | ||||||
| 19 | Automatic hand gun | US3780618D | 1971-05-20 | US3780618A | 1973-12-25 | SANFORD H |
| This invention relates to a recoil-actuated automatic hand gun, which provides for utilizing a maximum sized cartridge in a hand gun system. The reactive thrust as the bullet leaves the muzzle of this gun causes a barrel, barrel extension, receiver, and bolt to slide back locked together a set distance during initial motion until the bullet leaves the bore of the gun, and the gas pressure decreases to a level low enough to permit the safe unlocking of a locked breech action. The sliding receiver reaches its limit of travel and hits a portion of the frame of the pistol. A through-slot in the bolt bears cam surfaces which rotate the bolt out of breech-locking splines in the breech action thereby to release the bolt from engagement with the receiver and permit the inertia of the bolt to carry it backwards to perform ejection, cocking, and the loading of a new cartridge. In order to replace some of the dissipated energy and to increase the speed of travel of the bolt to load spring-return mechanisms, and to perform the functions of the bolt with the speed required, a rotary, mechanical accelerator forms a part of the action and imparts a blow to the bolt at the time that the receiver reaches its stop position. The bolt is rotated out of the breechlocked position by balanced cam follower means fixed to the frame that follow the cam surfaces, and upon return to the breechlocked lock position, the entire assembly travels as a unit to the battery position with a loaded cartridge in the chamber. A safety tappet pin engages a spiral groove in the bolt to prevent premature firing before the action has reached an appropriate position. The bolt is adapted with unique ejection means, which ejects the spent cartridge case forward and away from the shooter''s head and face.
