Definitions

  • the present invention relates to a breech wedge for artillery cannon, of the type comprising means for supporting a barrel with a stuffing box, the translation and rotation of said barrel being controlled by a pinion-rack assembly.
  • Such breech wedges are used in cannons intended to fire munitions comprising on the one hand a projectile, and on the other hand a propellant charge contained in a gargoyle or a combustible case.
  • the charge is ignited by means of a choke placed in a chamber formed at the rear of the breech wedge, and in communication by a light channel with the propellant charge placed at the entrance of the barrel.
  • the nipples are mounted on barrels allowing to bring into the chamber each shot fired, a new nipple not yet consumed.
  • Document FR-A-2,464,451 describes a cylinder head wedge of the type mentioned above.
  • the pinion-rack assembly is actuated by a lever secured to the pinion and a cam secured to the recoil slides of the weapon.
  • the striker is carried in this document by a carriage sliding on the breech corner and abutting on the sleeve in the percussion position, or releasing the gland holder barrel in the open position, using a T-slot system inclined with respect to the direction of movement of the corner.
  • the light channel is inclined and relatively long, and it does not emerge in the center of the shooting plate.
  • this breech wedge has a number of drawbacks.
  • the present invention seeks to overcome these drawbacks by providing a breech wedge in which the movements of the barrel are controlled directly by the translation of the wedge, without requiring an external mechanical part. It also aims to simplify the mechanism for holding the choke and percussion.
  • the subject of the invention is a breech wedge for an artillery cannon, of the type comprising means for supporting a barrel with a stuffing box, the translation and rotation of said barrel being controlled by an assembly consisting of a first pinion and a first rack, characterized in that said first pinion is mounted on a shaft supporting a second pinion arranged to cooperate with a second rack fixed to a fork mounted sliding on said corner, a control lever being pivotally mounted on the cylinder head sleeve and supporting a first roller arranged to cooperate with a groove of the fork so as to cause the sliding of the fork on the breech wedge, and a second roller arranged to cooperate with a groove in the wedge so as to cause the wedge to slide on the breech sleeve.
  • the second groove may in particular comprise a circular part centered on the axis of rotation of the control lever, so that the breech wedge remains substantially fixed relative to the breech sleeve during the rotation of the threaded barrel.
  • the two rollers can be mounted coaxially on the control lever, the parts of the grooves of the fork and of the cylinder head corner traversed by the rollers during the sliding of the corner on the cylinder head sleeve being superimposed when the fork is in its position where the The threaded barrel is engaged on the breech wedge.
  • the breech wedge according to the invention comprises a striker carrying carriage slidingly mounted on the wedge between a first position where the striker is located opposite a nipple to be struck, and a second position where the carriage releases the gland holder barrel, stops being provided on the cylinder head sleeve to cause the carriage to move relative to the corner, when the corner is displaced relative to the sleeve.
  • the carriage may be integral in translation with a rod sliding in a bore of the cylinder head sleeve, a stop of the rod cooperating with an abutment of the sleeve to bring the carriage into its said first position, when the closing of the cylinder head, and a stop of the carriage cooperating with another stop of the sleeve to bring the carriage into its said second position when the cylinder head opens.
  • the carriage may advantageously include an inclined surface arranged to cooperate with a corresponding surface of the nipple holder barrel to crimp the nipple in its housing, the resulting translational movement for said first rack, being absorbed by a torsional prestress of the 'support shaft of said first and second pinions.
  • the actuator of the striker of the breech wedge according to the invention can in particular be pivotally mounted on the wedge in a location such that it is only likely to actuate the striker when the carriage is in its said first position.
  • the breech wedge 1 is mounted in a known manner sliding on the breech sleeve 2, partially shown in broken lines in FIG. 1.
  • a mounting system 3 makes it possible to support a nipple holder barrel 4, in such a way that a nipple is placed in a nipple holder chamber 6 communicating with the barrel of the weapon by a light channel 7.
  • a pinion 8 and rack 9 system makes it possible to roll back the barrel and to rotate it with each shot fired.
  • the light channel extends along the axis of the barrel of the weapon.
  • the pinion 8 is mounted at the lower end of a torsion shaft 10 supporting at its upper part another pinion 11 (FIG. 3).
  • the shaft 10 is rotatably mounted in the cylinder head corner 1, prestressed so as to tend to bring the rack 9 back.
  • the breech wedge 1 supports a fork 12 slidably mounted using two sets of grooves and T, 13.
  • the fork 12 also includes a rack 14 arranged to cooperate with the pinion 11.
  • the sliding movement of the fork 12 with respect to the cylinder head corner 1 is controlled using a lever 15 shown in detail in FIGS. 5 and 6, and shown diagrammatically in three different positions by the dashed lines 15a, 15b and 15c in Figures 4a and 4b.
  • One end of the lever 15 comprises a sleeve 16 in which a grooved bore 17 is formed capable of cooperating with a corresponding grooved shaft mounted for rotation on the cylinder head sleeve. Only the axis 18 of this tree is shown in Figures 4a and 4b.
  • the lever 15 also carries at its other end, two coaxial rollers 19 and 20.
  • the roller 20 is engaged in a Z-shaped groove in the cylinder head corner 1 comprising a first rectilinear part 21, a circular part 22 centered on the axis 18, and a second rectilinear part 23.
  • the roller 19 is engaged in a rectilinear groove 24 of the fork 12.
  • the breech wedge 1 also supports a carriage 25 slidably mounted using a T-slot, 26.
  • the striker 27 is pivotally mounted on the carriage 25 via the axis 28 ( Figure 3 ).
  • a slider 29 is also slidably mounted on the cylinder head corner 1, using T-shaped grooves 30, and is made integral with the carriage 25 by a projecting member 31.
  • the slider 29 is also secured with a rod 32 mounted sliding in a bore 33 of the cylinder head sleeve 2.
  • the rod 32 carries at its end opposite to the slide 29, a nut 34 acting as a stop to cooperate with an abutment surface 35 of the cylinder head sleeve 2.
  • the carriage 25 has an abutment surface 36 capable of cooperating with a corresponding abutment surface 37 of the cylinder head sleeve 2.
  • An actuating member 38 of the striker 27 is pivotally mounted on the breech wedge about an axis 39.
  • the member 38 is rotatably connected to a shaft 40.
  • a rod 41 is mounted in a bore in the cylinder head corner 1 to move in translation against the action of a spring 42.
  • Unecame 43 makes it possible to transform the translational movement of the rod 41 into a rotational movement of the shaft 40, and therefore to operate the actuator 38 of the striker.
  • the roller 19 cooperating with the groove 24 therefore causes the fork 12 to move relative to the cylinder head corner 1 in the direction of arrow F2.
  • This displacement causes the pinion 11 to rotate in the direction of arrow F3 by means of the rack 14.
  • There follows a rotation of the shaft 10 and of the pinion 8 which, by means of the rack 9 causes the installation of a choke in the chamber 6, as described in the aforementioned document FR-A-2,464,451.
  • the front end of the nipple is crimped in the conical end part of the chamber 6, due to the cooperation of an inclined surface 44 of the carriage 25 with an inclined surface 45 of the nipple holder barrel 4 This crimping results in a twisting of the shaft 10 and results in perfect positioning of the chuck in its housing.
  • the lever 15 is first returned to its position 15b, which causes a displacement of the breech wedge in the direction of arrow F6, of FIG. 1.
  • the lever 15 causes the fork 12 to move in the opposite direction to the arrow F1, and, by a reverse movement to that described previously, the extraction and rotation of the stuffing box barrel.
