Definitions

  • the present invention finds its application in the field of artillery guns and relates to an automatic device for supplying chokes to initiate a propellant charge contained in an ammunition without cartridge case, with combustible cartridge case or in the form of gargoyles.
  • FR-A-1 268 250 describes a weapon comprising a magazine for tugs mounted interchangeably in the breech corner and produced so as to avoid manual loading thereof. A trolley is in contact with this store to ensure the ignition of ammunition.
  • This device had to meet certain requirements in order to allow an advantageous saving of time during firing maneuvers, such as for example the automaticity and the simplicity of changing the packing magazine.
  • the device also had to be very reliable since it is subjected to significant accelerations during the recoil phase of the gun.
  • the breech of the barrel is the seat of high mechanical stresses; for this the supply device for tows had to be placed in such a way that the cylinder head is not weakened, a disadvantage which could have been remedied by strengthening it, hence consequently a harmful increase in its mass.
  • the object of the present invention is to provide an automatic supply device for dowels meeting the various aforementioned conditions while being simple and of relatively low cost price.
  • the axis of the stuffing box is inclined at substantially 45 ° relative to the axis of the barrel tube, the stuffing box being arranged at one end of the breech of the barrel.
  • the device comprises a first set of slides made in the breech of the barrel and in the breech of the striker holder and arranged orthogonally with respect to the axis of the gland holder and a second set of slides made in the cylinder head sleeve and in the striker holder cylinder head and arranged parallel to the axis of the gland holder, the first set of slides cooperating with the second to allow the movement of the striker holder cylinder head during the change of pin operation.
  • the second set of Slides decouples when the striker holder cylinder head is sufficiently clear to allow passage of the stuffing box, the movement of the striker holder cylinder head being limited by a fixed stop relative to the cylinder head corner.
  • FIG. 1 there is shown the axis XX 'of the barrel tube, as well as the breech wedge 1 and part of the breech sleeve (2) in which the wedge slides on the surfaces 3a and 3b visible in the figure .
  • a hole 4 of axis YY 'called the ignition conduit is made in the breech corner 1. This conduit opens at one end towards the firing chamber of the barrel 5 and at the other end towards the packing chamber 6.
  • the device according to the invention comprises a ring holder 7 of circular shape, as shown in detail in FIG. 4, which holds n rings 8.
  • the number of pins, in this particular embodiment has been chosen equal to 12 for space requirements. It is understood that this number can be increased or reduced given the space available to accommodate the device in the cylinder head.
  • the chokes 8 are mounted on the choke holder so that their axes are parallel with the axis YY 'of the ignition pipe 4, one choke being in the choke chamber 6 while the others are placed in housings 9 provided in the breech corner. When changing the nipple, the nipple holder must be able to rotate so as to bring an unconsumed nipple into the nipple chamber.
  • the stuffing box must rotate stepwise by axis ZZ 'parallel to the ignition pipe.
  • This step-by-step rotation takes place during the translation of the gland holder along the axis ZZ ', which is carried out by means of a pinion 10 pair of axis 10a - rack 11.
  • the rotation takes place when the pins are out of the housings 9 and of the chamber 6.
  • the rack can slide along the axis ZZ ', is integral with the stuffing box 7 and is actuated by the pinion 10 integral with the lever 12 controlled during the opening of the barrel breech.
  • the rack 11 is a circular rack to allow the simultaneous movement of rotation and translation of the stuffing box.
  • the rotation movement of the stuffing box is effected by means of grooves 13a and 13b formed on the shaft 14 (shown in FIGS. 5 and 6), which cooperate with grooves 15 of a grooved ring 16 (shown in FIGS. 7 and 8).
  • the splined shaft has, according to its generatrices two sets 13a and 13b of male splines, the two sets being separated by a distance D and being offset by ⁇ .
  • the number of splines n of the two sets must be equal to the number of pins placed on the gland holder.
  • These grooves are provided with chamfers 17 a and 17 b of angle ⁇ relative to the generatices of the shaft and forming between them an angle of ( ⁇ -2 ⁇ ).
  • the grooved ring has n female grooves 18 (shown in Figure 8) which can slide along the male grooves 13 a or 13b of the shaft 14.
  • the height of this ring is slightly greater than the distance D so that l the shaft is still engaged on the ring.
  • the ends of the male grooves 15 formed between the female grooves of the ring are provided with chamfers 19 of the same angle ⁇ as those formed on the shaft and forming between them an angle of ( ⁇ -2 ⁇ ).
  • the grooved ring 16 is made integral with the breech wedge by means of a nut 20 and a tongue 21 housed in a groove 23 in the breech wedge.
  • the gland holder as shown in Figure 4, is composed of two disc-shaped parts 24 and 25, secured by a nut 26 and a positioning finger 27.
  • the rear bottoms 28 of the pins are trapped between your two parts 24 and 25.
  • the assembly thus formed is secured to the splined shaft 14 by means of a tenon 29, for example of hexagonal shape, and by a pin 30.
  • a variant consists in embedding the bottoms of the studs in a block, for example made of plastic, which has the role of replacing the parts 24 and 25 as well as the nut 26 and the finger 27. In both cases, the packing holder assembly constitutes an easily removable means allowing the quick change of the stuffing box.
  • the disc-shaped part 24 also has holes 31, aligned with the axes of the nipples and allowing the passage of the striker 32 which is housed in the striker holder cylinder head 33 and which is supported on the surface 35 of the nipple holder when the breech corner is closed.
  • the striker 32 is kept retracted by means of a spring 36 held by a nut 37 and is actuated at the appropriate time by an auxiliary device, not shown because it is easily imaginable by those skilled in the art.
  • the striker carrier cylinder head 33 is held on the cylinder head corner by a set of slides 38 and is subjected to the action of spring 39 limited by the stop 40 fixed on the cylinder head corner.
  • a second set of runners 41 a and 41 b disposed respectively on the striker holder cylinder head and on the breech sleeve, allows the striker holder cylinder head to disengage the gland holder so as to allow it to move back.
  • the slides 41a and 41b are uncoupled, and the striker carrier cylinder head is held against the stop 40 (see FIG. 2).
  • the operation of the device according to the invention is described below.
  • the breech wedge is closed (see FIG. 1), the striker 32 is actuated and ignites the choke 8 which, via the channel 4, initiates the ammunition placed in the chamber 5 of the barrel.
  • the shot fired we open the breech corner (see Figure 2); the striker holder cylinder head is driven by its slides 41 a and releases the stuffing box.
  • the lever 12 is automatically actuated and drives the pinion 10 as well as the circular rack 11 and the shaft 14 which moves in the grooved ring 16.
  • the chamfers 17b and 19 come into contact (see Figure 10) and rotate the shaft 14 of Then, the new ammunition is placed in the barrel chamber and the breech wedge is closed.
