Definitions
- the present invention concerns a mechanism for loading and feeding a semi-automatic rifle and its operating method.
- the invention concerns a mechanism for loading and feeding the cartridge in the chamber of an inertia operation semi-automatic hunting rifle with shot cartridges.
- the breechblock In feeding and loading systems currently existing, the breechblock remains in open position only thanks to the presence of levers or buttons which, on the one hand make the rifle more complex as well as expensive, but on the other hand make the replacement of the cartridge impractical.
- the breechblock remains open only if held with the hand which simultaneously supports the weight of the rifle, whereas with the other hand the changing of the cartridge is carried out.
- the breechblock is taken to the switch limit unlocking a cartridge from the tank tube and taking it into the chamber preventing the replacement and insertion of an outer cartridge taken from the cartridge belt.
- the purpose of the present invention is that of providing a mechanism for loading and feeding a semi-automatic rifle which allows the aforementioned drawbacks to be avoided providing a simple and safe system which allows the loading and replacement of the cartridge from the chamber in any easy and quick manner, an operation which is, moreover, frequent in the case of a tank which fires just three shots.
- This purpose according to the present invention is accomplished by realising a loading and feeding mechanism according to that which is outlined in claim 1.
- An operating method of the mechanism according to the invention forms the object of claim 8 and thereafter.
- the mechanism for loading and feeding a semi-automatic rifle comprises a lifter and a lifting stop tooth suitable for unlocking the lifter and taking the breechblock group to the switch limit, allows the breechblock carrier to always be kept open, both with cartridges in the tank and in the absence of cartridges, without the need to hold it by hand and without the help of specific levers or buttons intended for the purpose, in this way allowing easy loading and fast replacement of the cartridge in the chamber.
- a casing 10 of a semi-automatic hunting rifle houses, inside of its housing 11, the sear, loading and feed mechanisms for the firing of shot cartridges 12.
- a breechblock carrier 14 slides carrying, arranged inside of it, the breechblock 15.
- an inertia spring 16 is placed the function of which is that of compressing during the backwards motion, or recoil, of the breechblock 15 following firing to then restore its elastic energy, until a certain compression threshold is exceeded, trusting the breechblock carrier 14 which possesses a relatively large mass.
- the breechblock carrier 14 in backwards motion recoils and frees the latch 17 protruding from the breechblock 15.
- Said latch 17, during the whole of the firing step is engaged in a seat 18 realised in the breech 13 so as to lock making the breech 13 and the breechblock 15 integral.
- the latch 17 engages at the bottom with a cocking clip 19 consisting of a pin which crosses the breechblock 15, to allow its unlocking once a shot is fired.
- a firing pin 20 is arranged along the longitudinal axis of the breechblock carrier 14 and of the breechblock in a central position to strike the centre of the base plate 21 of the cartridge 12, when it is inserted in the chamber 23 of the rifle.
- the capsule is arranged which, struck by the firing pin 20, starts of the blast.
- the feeding and loading mechanism comprises a cartridge stopping lever 30 arranged on one side of the housing and having an actuation dowel 31, which acts as a hinge being pivoted along the side of the housing, and a return spring 32 which takes the lever back into rest position.
- the lever 30 With one of its two ends 30' the lever 30 makes contact with the base plate of the cartridge 12 present at the inlet of a tank tube 33 intended for housing the cartridges and arranged below the chamber.
- the feeding and loading mechanism also comprises a lifter 35 or spoon, intended to lift a cartridge 12 from the level of the tank tube 33 to the level of the overlying chamber 23 for loading.
- the lifter 35 is locked in lowered position until a new cartridge 12 arrives, through engagement of a stop tooth 36 of the lifter arranged near to the rear portion of the lifter 35 with respect to the inlet end of the cartridge 12.
- the breechblock carrier 14 After firing, the breechblock carrier 14 recoils and continues its stroke until the cartridge case is ejected, after which it either remains open held by a breechblock stop tooth 37, or it returns into locking position putting another cartridge in the chamber.
- the sear mechanism comprising a hammer 38, ratchets and pivoting pins suitable, respectively, for holding the mechanisms and for allowing the rotation thereof, and a trigger 39 through which the user can act to fire.
