| 1 | Reduced recoil caseless cartridge machine gun | US3641867D | 1970-03-11 | US3641867A | 1972-02-15 | JUNKER RALPH DANIEL |
| A forward flow, chamber-gas-pressure-actuated automatic firearm employing caseless ammunition and nonmoving barrel. Chamber bolt blown forward parallel to the bore, permitting antirecoil gas thrust and counterrecoil impact of parts operating forward opening breech mechanism in the form of a gas check ball valve. Provides for accelerated autoloading of projectile and subsequent feeding of solid propellant charge in such a manner that the projectile is seated in the bore and the breech sealed before the front-loading charge is delivered to the ignition portion of the chamber.

| A permeable barrel for accelerating a projectile is provided. The barrel includes a plurality of holes through which gas can be injected to generate a gas cushion for the projectile. The gas cushion prevents any contact between the projectile and the barrel walls. Also the gas cushion helps to keep the projectile centered in the barrel throughout its travel. | ||||||

| 8 | Device for recoilless firing of a missile | US797644 | 1977-05-16 | US4151780A | 1979-05-01 | Claes R. Andersson |
| A device providing for the recoilless firing of a missile from a launching tube and comprising a gas generator surrounding a rear portion of the tube, with a plurality of apertures formed in the tube and positioned to allow high pressure gas to pass from the gas generator into an area behind the missile to provide a sufficient launch force. | ||||||

| A firearm includes a housing having a detonation chamber and a projectile-discharge barrel. A displaceable piston is mounted at the discharge end of the barrel and is arranged to be acted upon and extended by combustion gases expelled from the barrel. Forward movement of the piston is transmitted to the housing in a manner tending to counteract recoil. The detonation chamber is arranged to receive a compression-responsive cartridge. A cartridge-detonating bolt is mounted within the bolt for reciprocal movement between cocked and discharge positions. A bolt-follower includes a locking device which is operable to temporarily lock the bolt against return movement to a cocked position while enabling the bolt to rotate. A cam-like configuration of the working end of the bolt compresses the cartridge in response to rotation of the bolt. The bolt-follower is coupled to the displaceable piston such that detonation-induced forward movement of the piston shifts the bolt-follower to an unlocking position. Actuating linkage is provided for transmitting bolt movement to the loading mechanisms of the firearm. | ||||||
