Definitions

  • the weapons concerned by the present invention are of preferably large caliber artillery weapons which include a sleeve cylinder head system and a wedge cylinder head which can slide in the sleeve.
  • the placement of ammunition in the gun chamber is done using a repressor which pushes the ammunition on the upper part of the base of this one.
  • the ammunition is brought by a loading tube which comes place near the gun sleeve.
  • the ammunition is therefore not brought until the entry of the ammunition chamber.
  • the object of the present invention is to resolve the aforementioned problems, by proposing a weapon which allows facilitate the placement of ammunition, while with great safety in use during loading.
  • the weapon targeted by the invention includes a wedge movable breech between a closed position, in which the breech block closes an ammunition chamber, and a open position, in which the chamber is open for receive ammunition from a loading tube, latch means being adapted to hold the wedge cylinder head in open position, characterized in that unlocking means are mounted on the tube loading and are suitable for placing the means forming latch in the unlocked position, when the load is moved away from the ammunition chamber.
  • the breech wedge is unlocked by the loading tube, only when this one and moved away in the ammunition chamber, after having introduces ammunition.
  • means forming a lock exert a locking force substantially opposed to a restoring force exerted on the breech wedge by elastic return means and adapted to move said breech wedge from position open to the closed position.
  • the loading tube is suitable to be positioned adjacent to the chamber ammunition.
  • the weapon 10 targeted by the present invention comprises a breech wedge 12 movable between a closed position, in which the breech wedge 12 closes off a chamber 17, and an open position, in which the chamber 17 is open to receive ammunition from a loading tube 13.
  • means forming latch 16 are adapted to hold said corner of cylinder head 12 in the open position and means for unlocking 14 adapted to place the means forming latch in the unlocked position, when the load 13 is moved opposite chamber 17, are mounted on the loading tube 13.
  • the corner breech 12 is opened by a cocking lever 40 one end of which is engaged inside a housing 41 provided in the cylinder head corner, preferably near its base.
  • the latch means 16 exert a locking force substantially opposite to a force return force exerted on the breech wedge 12 by elastic return means adapted to move the breech wedge 12 from open position to position closed.
  • means of elastic return 36 can be a working spring in compression.
  • the force lock is applied directly to the corner of cylinder head 12, preferably near the part bottom of the breech wedge.
  • the automatic loading tube 13 comes thus in contact with chamber 17 and a repressor central (not shown) performs the stationing of the ammunition in the room.
  • Maintaining the munition at the interior of chamber 17 is produced by means of a retractable stop not shown and which is good described in patent application No. 8702241.
  • the loading tube 13 is therefore positioned above the cylinder head 12 when loading weapon 10.
  • the means forming lock 16 and the means of unlocking 14 are adapted to retract one by relative to each other when the loading tube 13 is moved to room 17, that is, when pass over the breech wedge 12, and coming in taken with each other when the loading tube 13 is moved opposite chamber 17 so as to place the latch means 16 in the position unlocked.
  • the retractable member 24 comprises at its projecting end, a surface 24a forming a pan tilted outward from weapon 10 and a surface 24b substantially vertical directed towards the interior of weapon 10.
  • the retractable member 24 can slide in translation inside the body 16b of the means forming a lock 16, in a T-shaped groove 19 as illustrated in Figures 4 and 5.
  • the return means 29 projecting from the organ 24 is a spring which is placed between two housings 28 and 30 which are drilled respectively at the interior of the retractable member 24 and of the body 16b means forming a lock 16.
  • Stop in translation of the organ retractable which is moved by the return force exerted by the spring 29, is produced by means of a pin 25 mounted in a bore 26, through the retractable member, which moves inside a light 18, formed in the body 16b and parallel to the direction of movement in translation of the retractable member, and which abuts the upper end of this light 18.
  • the surface 14b of the means of lock 14 is substantially vertical and comes therefore engaged with the corresponding surface 24b of the retractable member 24 when the loading tube 13 comes out of the weapon 10 away from the chamber 17.
  • cam 30 When the cam is rotated, a portion of cam 30, further from its axis of rotation than the rest of the cam, that is to say constituted by the part in tip 30a of the ovoid cam 30, comes into contact with a wall of the housing 22 and thus exerts a force on all of the means forming a lock 16. These are then displaced in pivoting around the axis of rotation 21, against the action of the return spring 23, so as to release the locking hooks 16a from the lugs 12a of the breech wedge 12.
