Definitions

  • the technical field of the present invention is that of firing devices for artillery by percussion of the nipples.
  • Artillery firing devices include in a known manner a striker subjected to the action of a spring.
  • This spring being compressed, it constrains the striker in a rear armed position throughout the use of the weapon, that is to say as long as the fire is not started.
  • the striker is released, the spring projects it onto the primer the choke to ensure ignition.
  • US-A-2,245,621 which describes a striker like this where this one is returned to the armed position when the cylinder head. It is not desirable to use such a system as it is likely to lead to updates untimely fire, which can be very dangerous for the servants of the weapon.
  • Patent DE147526 describes a firing device for an artillery comprising a striker subjected to the action of a spring.
  • a latch stopper allows roll back the striker by bandaging its spring, when of the rotation of an arming lever. This last fact pivot a second lever around an axis which has a pawl cooperating with the latch. At the end of rotation cocking lever, the pawl detaches from the latch that releases the striker.
  • the object of the present invention is to provide a new concept for maneuvering a non-entraining striker no constant tensioning of a spring coupled to it striker and reduced size.
  • a first notch presents a cylindrical profile, in which the pawl begins its rotation, followed by a second notch in which clears the pawl to allow rotation of the lever around its axis.
  • the second notch has a depth corresponding to the percussion stroke of the striker.
  • the heel is located beyond the second notch to cooperate with a ramp fitted on the lever to return it to the initial position.
  • the rod is returned to the initial position by a return spring and it is driven in translation at using a hydraulic cylinder.
  • the lever projection means consists of a arm of which one end is supported on the lever and the other rigidly attached to a torsion bar, the other end of the arm and the bar being fixed to the support.
  • the lever has one end fixed to the striker and the other fixed to an axis of rotation relative to the support, the pawl being rotatably mounted relative to this lever at a point between its two ends.
  • the torsion bar is initially put in prestressing.
  • the lever can be realized in the form of a plate with days to reduce its moment of inertia.
  • the pawl is coupled to the lever by through a spring.
  • the striker has a first groove perpendicular to the axis of the striker in which the end of the lever is engaged and a pawn emerging therein, to maintain the lever in this groove.
  • the striker is provided with means allowing its extraction comprising at least two notches on its face rear to allow its grip, and a second groove parallel to the striker axis communicating with the first groove, the lever traversing the second groove after erasing the pawn and rotating the striker.
  • a very first result of the device according to the invention resides in that the striker is always in rest position even when the breech of the weapon is closed.
  • Another advantage is the possibility of adjusting the prestressing of the torsion bar.
  • Another advantage is the compactness of the Firing.
  • FIG. 1 there is shown a partial section of the weapon at the pin striker in the longitudinal direction.
  • the support 1 corresponding to the rear part of the weapon (no shown) on which the different elements necessary for understanding the invention are represented.
  • the weapon is equipped with a striker 2 slidably mounted in an integral housing 3 of the support 1.
  • a set of pins (not shown) is arranged facing the tip of this striker and these nipples are initiated as and when percussion during translation of the striker.
  • the striker 2 is coupled to actuation means consisting mainly of a lever 4, a pawl 9, a projection means in the form of an arm 11 and a bar twist 18 and drive means appearing under the shape of a movable rod 12.
  • the lever 4 is articulated in a yoke 5 secured to the support 1.
  • Lever 4 has a number of 7 days intended to lighten it to decrease its moment of inertia with respect to its axis of rotation 6 and decrease thus the response time of the percussion.
  • Leverage 4 is provided with a face 8 on which a pawl 9, mounted rotatable relative to this lever around an axis 10, is maintained in constant support (in the direction of the arrow) via a return spring not represented.
  • Arm 11 is engaged in one of the days, day 7a for example, to drive lever 4 as it will explained below.
  • the rod 12 arranged substantially parallel to the lever 4 is slidably mounted in a clevis 13 fixed to support 1 and is coupled to a spring 14 whose role is to bring it back to its original position such that shown schematically in Figure 1.
  • the rod 12 is provided a first cylindrical notch 15, a second notch 16 and a heel 17.
  • the pawl 9 is susceptible to occupy the first and second notches like this will be explained later when a movement of traction is exerted on the rod 12.
  • FIG 2 there is shown in bottom view the support 1, striker 2, lever 4 and rod 12 coupled to its spring 14.
  • the arm 11 is linked mechanically at the end of a torsion bar 18 arranged in a housing 19 formed in the support 1.
  • the other end of the torsion bar 18 is fixed rigidly in the housing 19, for example using of a plate 20.
  • Percussion is performed as follows.
  • Figure 4 illustrates a final phase of operation in which the pawl 9 has engaged in the notch 16 as a result of a translation additional rod 12.
  • the pawl 9 being suddenly escaped into notch 16, the bar of twist 18 can then relax and project strongly the striker 2 under the action of the arm 11 towards the initiation of the suffocation to initiate it.
  • the rearming is done as follows.
  • the striker 2 is returned to the initial position, that is to say in the rest position shown on the Figure 1, under the action of the spring 14.
  • the spring 14 is compressed when the rod 12 is pulled by the hydraulic cylinder.
  • the spring 14 brings the rod 12 in the direction opposite of arrow F and heel 17 of rod runs along a ramp 21 arranged on the lever 4 as shown in Figure 4.
  • This lever 4 is pushed back and the pawl 9 is released from notch 16 by pivoting around its axis 10 passing through the position intermediate shown in Figure 3 and comes occupy the initial position shown in Figure 1 going back to notch 15.
  • the pawl 9 returns to bear on the face 8 of the lever 4.
  • a new cycle can then start again.
  • FIG 5 there is shown the arm 11 actuating the lever 4.
  • the arm 11 is housed in a housing 22 made in the support 1.
  • a end of the arm 11 is integral with the torsion bar 18 and the other end is engaged in day 7a of lever 4.
  • FIG 6 there is shown a section longitudinal of striker 2 which has a first groove 23 perpendicular to the axis of the striker, a second groove 24 parallel to the axis of the striker and a connection 25 of these two grooves.
  • the lever 4 is positioned in the first groove 23 and its travel is limited by a pin 26 opening into the first groove 23 (see Figure 7).
  • This pawn is placed in a housing 27 of the striker and is located pushed by a spring 28 blocked by a screwed plug 29 in the housing 27.
  • the housing 27 and the pin 26 are each provided with a shoulder allowing fix the final position of the pawn.
  • the striker 2 can be removed from its housing in case exchange or to neutralize it.
  • the striker 2 is provided on its rear face with two notches 30 (FIG. 6) in which there is positioned a tool that turns the striker a quarter of turn.
  • the rotation of the striker 2 causes the counter to move back 26 against the elastic thrust of the spring 28 and the lever 4 can then pass from the first groove 23 to the second groove 24.
  • the striker can then be extract from his home. To replace the striker, does the opposite.
