Definitions

  • the subject of the invention is an automatic rifle, with a tilting barrel or not, operating by borrowing gas.
  • the aim sought after according to the invention resided in the design of a new rifle operating by borrowing gas by using the energy of these to atuorise the advance of the barrel and simultaneously the extraction of the fired cartridge and the introduction a new cartridge from the magazine tube.
  • the rifle proposed according to the invention is of great reliability and speed of operation, loading and unloading.
  • the weapon is shorter by approximately 7 to 10 centimeters compared to similar rifles operating by borrowing gas.
  • the rifle obtained according to the invention has a new aesthetic which gives it a particular appeal.
  • the barrel is mounted with a capacity of displacement forwards with respect to the magazine tube; the front part of said barrel receiving in its lower part a sheath internally constituting a gas expansion chamber in communication with the barrel; said store tube having an extension partially engaging in the sheath without closing the gas passage opening; a piston sliding in said sheath under the thrust of the gases and acting against the recovery spring of the barrel by means of a means for unlocking the barrel and its displacement relative to the magazine tube; said means being subject to a pair of rods sliding along the magazine tube and the rocker to authorize the arming of the hammer hammer and the ascent of the cartridge lifting means in the barrel tube.
  • the rifle comprises a profiled carcass (1) forming a rocker at its front end and arranged at the rear for fixing in a conventional manner the stock (2).
  • the key (3) for opening the barrel, the trigger tail (4), the extractor (5), the hammer (6), the other means known per se, such as the trigger, the trigger, have been illustrated diagrammatically. the cylinder head and other main means generally used, not being glossy for clarity of designs.
  • the barrel (7) is mounted with a sliding capacity by appropriate grooves (8) along the magazine tube (9) pivotally mounted on the pin (10) at the end of the rocker.
  • the magazine tube is arranged to internally receive several cartridges (11) held in position by a suitable stop notch (12) against a detent spring (13) disposed at the bottom of said magazine.
  • a sleeve (14) having a bearing surface (15) for connection and communication with the interior of the barrel for the passage of gases.
  • the front store tube is extended directly or indirectly by an insert tubular means for partially engaging in the internal bore of said sheath until it comes to substantially tangent, without however closing it, the opening (16) of passage of gases from the barrel to the gas expansion chamber of said sheath in the initial position.
  • a piston (17) located near the gas passage opening and beyond it and moving to come opposite the bottom face (14-1) before scabbard.
  • the rod (18) of the piston passes through the front part of the extension of the magazine tube and is associated at its end according to a first embodiment with a means produced in the form of an attached element (19) constituting a ring or collar capable of sliding in being guided along the magazine tube.
  • the recovery spring (20) of the barrel which is held in position by the end (9-1) of the magazine tube and an internal bearing face (19-1) of the ring. (19).
  • the ring (19) and the magazine tube are arranged with a cutout forming a notch (19-2) profiled together forming the seat of a tilting bolt (22) whose axis (23) is integral with the barrel.
  • the latch (22) in the rest position, the latch (22) is locked in position and is released only when the ring moves forwards after the shot also emerges from the notch portion of the tube store.
  • the rod (24) associated with the ring (19) has at the end of a notch (24-1) capable of fitting into a complementary shape (25-1) established at the front end and opposite the second rod (25) when closing the barrel, the two rods being thus closely associated in their movement during the firing operation of the rifle.
  • the rod (25) is arranged with a reduction in section along its length defining a stop face (25-2) against which will come to bear a finger (27) disposed in overflow on the percussion hammer (6) causing at the end of stroke, against a return spring (28) tilting and arming.
  • a finger disposed in overflow on the percussion hammer (6) causing at the end of stroke, against a return spring (28) tilting and arming.
  • Figure 5 the dog is held in position by the trigger subject to the trigger not shown in the drawings. As long as the rod (25) has not gone back, the dog cannot be struck.
  • the rod (25) arms the hammer percussion for additional shots but during the first shot, the dog is armed by the tilting of the elevator, as will be specified later.
  • the rod (25) further comprises, in its rear part, an upper heel (25-3) forming an ejector. When the rod (25) is at the front end of travel, it causes the ejection of the drawn cartridge retained by the extractor.
  • the rod (25) has in its rear lower part a lug (29) capable of cooperating with the elevator (26) as illustrated in FIGS. 6 to 8 showing the different phases during the displacement of the rod (25 ).
  • the elevator (26) comprises a loading lever (26-1) articulated in its rear part on an axis (26-2) and extending with an external part forming a cam (26-3) also articulated on said axis to the 'against an elastic return means (30), one end (30-1) is fixed to the loading lever.
  • the elevator is stressed in movement by the displacement of the rod (25) under the following conditions.
  • the rod (25) In the initial position, the rod (25) is set back from the elevator. Following the driving movement given by the lever (24) during the displacement of the piston (17) in the gas expansion chamber, the rod (25) moves forward so that the lug (29) comes to bear on the cam (26-3) which disappears by tilting against the aforementioned elastic return means (30) which is compressed.
  • the lug (29) being located in front of the cam (26-3), the latter returns to position by the rebound effect of the spring.
  • the rod (25) returns to its initial position, the lug (29) will again come into abutment on the cam (26-3) but on the other side of the latter.
  • Said cam can not tilt in the opposite direction, the action of the lug (29) will cause the tilting of the elevator (26) relative to its axis of articulation and thus authorize the load ment of a new cartridge in the rifle barrel, when returning to its initial position, Figures 13 and 14.
  • the lifting means performs a second function in the case of the tilting barrel.
  • the front end (26-4) of the loading lever (26) is substantially supported on the metal part (35), known per se, associated with the front of the barrel (36).
  • the loading lever is thus tilted relative to its articulation axis (26-2) and undergoes a pivoting movement.
  • the end (6-1) of the dog (6) which is in contact with said loading lever (26) is thus tilted relative to its axis of articulation, against its return spring and thus armed.
  • the arming of the dog for other shots is carried out in the manner described above.
  • FIG. 17, 18, 19, 20, 21, 22 Another embodiment of the barrel locking mechanism for loading is illustrated in Figures 17, 18, 19, 20, 21, 22, the piston (32) performing the same function as the piston (17) in the implementation previous, includes directly or in a reported manner a tubular intermediate body (32-1) of small diameter inserted in the front extension of the magazine tube (9), a front end (32-2) cooperating inside the sheath under the thrust of the gases, and a rear part established in the form of a cylindrical sleeve (32-3) slidingly adjusting in the magazine tube. Inside the piston is mounted a pin (33) in a fixed position, secured by its front part (33-1) by screwing and detachably to the outer front face of the sheath.
  • the rear end of said axis has a bearing surface (33-2) of larger section fitting inside the sleeve part (32-3) of the piston.
  • the recovery spring (20) of the barrel is mounted around the intermediate body of the piston and bears against the outside face of the manhole cover, and the bottom (9-1) of the magazine tube.
  • a locking means is provided. from the barrel.
  • This means consists of a finger (34) disposed on the rear bearing surface (33-2) of said axis radially outwardly adjusting and cooperating in a slot (32-4) established on the sleeve of the piston.
  • This slot is disposed angularly relative to the longitudinal axis of the piston.
  • This groove has a notch (21-1) in the form of a bayonet serving as a means of housing and locking the finger (34).
  • the operation is as follows.
  • the piston (32) When fired under the thrust of gas action, the piston (32) is subjected to a forward movement.
  • the slot (32-4) acting as a cam the finger (34) is tilted angularly by a few degrees thereby allowing it to escape from the notch or notch (21-1) established on the magazine tube.
  • the finger (34) can then slide in a controlled and limited manner in abutment by the bottom of the groove thus authorizing the displacement of the barrel-barrel assembly.
  • the finger (34) gradually returns to the reverse position; at the end of the groove (21), the finger moves angularly under the final action of relaxation of the spring and locks in the notch (21-1) blocking the barrel in position.
  • This second embodiment of the barrel locking mechanism is easy to produce in the manufacture of parts and allows the barrel to be changed easily since it suffices to loosen the fixing screw of the axle (33).
  • FIG. 23 Illustrated in Figure 23, the alternative embodiment which comprises in addition to the various mechanisms described above, a sup movable (31) movable and movable relative to the magazine tube.
  • This part performs the function of a plunger with two lateral flanges (31-1) (31-2) provided with an opening for sliding on the magazine tube.
  • the lateral flange (31-1) is disposed relative to the ring (19) by serving as a rear stop means.
  • the lateral flange (31-2) is intended to bear against the opposite face of the sheath (14).
  • the pusher is attached to the front part of the wood.
  • the shooter acts directly on the pusher element (31) which thus displaces the ring (19) forwards, thus ensuring the unlocking of the barrel by escaping the lock.
  • the pusher By its front flange (31-2) the pusher abuts against the sheath (14) integral with the barrel allowing the movement of the assembly and the introduction of a new cartridge into the barrel.
  • the filling of the magazine tube is carried out from below the rifle in a conventional manner.
  • the locking mechanism of the barrel can be similar to that illustrated in FIGS. 17 to 22 of the Application, as illustrated in FIG. 24.
