| 65 | WEAPON SYSTEM WITH SHORT RECOIL IMPULSE AVERAGING OPERATING GROUP | US13562078 | 2012-07-30 | US20140076145A1 | 2014-03-20 | 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. | ||||||

| A semi-automatic rifle including a recoiling barrel adapted to carry rearward the elongated bolt carrier containing the bolt for compressing the recoil spring, and a self-unlocking device including a self-unlocking rod longitudinally slidably mounted on the bolt carrier normally engaging the rear face of the barrel in a battery position and a trigger actuating device for thrusting the self-unlocking rod forward during the early stage of recoil for separation of the bolt carrier from the barrel before the barrel reaches the end of its recoil movement. | ||||||
| 70 | Automatic firearms with bolt assisted by an additional mass | US470841 | 1974-05-17 | US3930433A | 1976-01-06 | Jean-Claude Marie Minaire |
| An automatic firearm has a recoiling bolt connected by an amplifying lever to an additional mass subjected to the action of a recoil spring. One arm of the lever, via a push member, holds in a position of rest a stop pawl which is capable, when it is in active position, of retaining a striking hammer in striking position. The breaking of the lever permits the movement into the active position. | ||||||
| 71 | Automatic hand gun | US36015973 | 1973-05-14 | US3889574A | 1975-06-17 | SANFORD HARRY W |
| 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, barrrel 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 the 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 breech-locked position by balanced cam follower means fixed to the frame that follow the cam surfaces, and upon return to the breech-locked 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.

| 72 | Machine gun having dual feeding means for selectively feeding cartridges | US25124472 | 1972-05-08 | US3802313A | 1974-04-09 | ROCHA J |
| This disclosure relates to machine guns. Its features include: two feeding means mounted in tandem in a feed tray slideably mounted on the gun receiver for selectively feeding cartridges from two separate cartridge belts; receiver operating slide inertia control comprising energy absorption means responsive to the rate of movement of the operating slide effective to compensate for different cartridge propellant characteristics by absorbing increasing amounts of slide energy at increasing slide speeds; quick release mounting for the receiver and barrel including a retaining element, a receiver element removably supported in the retaining element and a barrel element removably supported both in the receiver element and the retaining element; a removable receiver back plate with locking means effective to prevent removal of the back plate when the operating slide springs are dangerously compressed in cocked position; an accelerator in contact with both the barrel actuator and the operating slide for immediate operation of the slide upon firing; a cable secured to the operating slide provided with a handle for cocking the operating slide; and a novel buffer for cushioning the movement of the barrel into firing position.

| 73 | Automatic gun receiver combination | US3566744D | 1969-07-14 | US3566744A | 1971-03-02 | STONER EUGENE M |
| The automatic gun receiver combination includes a recoiling barrel, bolt and bolt carrier, two ammunition feeding means, recoil assembly and buffer assembly. The recoiling barrel reciprocates axially in the receiver forwardly of the ammunition feeding means. A bolt is reciprocated axially past the feeding means by a recoiling bolt carrier. The bolt is also rotated into and out of a position in which it is locked to the barrel. Two cams extend along the length of the bolt carrier to cooperate with cam followers on each of the two ammunition feeding means, either of which may be selected to feed ammunition into the receiver. The recoil assembly is coupled between the barrel and receiver both for buffering recoil and counterrecoil of the barrel and for accelerating the bolt carrier in recoil relative to the barrel. The buffer assembly at the rear of the receiver both buffers the recoil force of the bolt and bolt carrier and mounts a sear, selectively engageable with the bolt carrier, such that when the sear and bolt carrier are engaged, the resulting interruption of the counterrecoil of the bolt and bolt carrier is buffered.
