Definitions

  • the technical field of the present invention is that of devices for loading ammunition into the chamber of a weapon mounted in a tank turret.
  • the barrel In a tank turret, the barrel is loaded by a servant who loads the ammunition into the weapon either manually or using a loading shovel. But when the turret is equipped with automatic loading there is no longer a servant and the smallness of the available space makes it impossible to manually load the weapon. In addition, at the end of the race, the ammunition must receive sufficient energy to introduce it into the chamber of the weapon. It is therefore essential to be able to load the weapon in the event of an automatic loading failure and more generally to have a loading device that can be used in all circumstances.
  • the purpose of the present invention is to provide a rustic loading device, compact, reliable and easy to implement.
  • the invention therefore relates to a manual loading device for a cannon integrated into an armored vehicle turret, characterized in that it consists of a means for receiving ammunition secured to the turret basket, a pusher delivery of the ammunition engaged on its base said pusher being driven by a closed chain, and a manual drive means of the chain, the chain and the drive means being integral with the receiving means.
  • the receiving means is integral with a slide ensuring a storage position from which the ammunition is removed and a loading position in line with the barrel.
  • the receiving means consists of a plate and two half-shells articulated relative to the latter.
  • the plate consists of a substantially rectangular plate provided with a flange at the base of which the ammunition is supported.
  • the pusher is integral with a carriage sliding on a slide fixed to the plate in parallel to the latter.
  • the pusher is in the form of a U-shaped part, a large branch of which bears on the base of the ammunition and the small branch of which cooperates with the chain to repress the ammunition, said pusher being articulated relative to the carriage.
  • the closed chain is driven in translation around two rollers each disposed at the ends of the plate and carries a lug cooperating with the pusher.
  • the chain is driven in an endless translation using a pinion actuated by a motor means which consists of a ratchet wheel actuated in rotation and meshing on a pinion drive shaft , said wheel being rotated by a drum actuated by means consisting of a cable and a handle and subjected to the action of a return spring.
  • a motor means which consists of a ratchet wheel actuated in rotation and meshing on a pinion drive shaft , said wheel being rotated by a drum actuated by means consisting of a cable and a handle and subjected to the action of a return spring.
  • a very first advantage of the invention lies in the fact that the device ensures the transport and transfer of generally heavy ammunition in an ergonomically inaccessible location.
  • Another advantage is the possibility of printing sufficient energy at the end of the ammunition to introduce it into the chamber of the weapon.
  • a removable device 7 is provided sliding on a deployable slide 8 fixed to an upright 9 secured to the turret belt 10 2.
  • an ammunition 3 is removed manually from the magazine 11 which is placed on the receiving means of the device 7 as shown in FIG. 1 and the slide 8 is deployed according to the arrow .
  • the device 7 is brought as shown in FIG. 2 vertically from the barrel 1 behind the breech sleeve 5 as illustrated in FIG. 3.
  • the weapon is brought, by rotation around a pin 12 according to the arrow at the loading site shown in FIG. 4 and the device 7 tilted around a point of articulation 13 along the arrow so that the axis of the ammunition 3 is aligned with the axis of the barrel 1.
  • the device 7 partially shown in Figures 5 and 6 comprises a receiving means 20 sliding on the slide 8 consisting of a first arm 8a fixed to the upright 9 and a second arm 8b articulated relative to the first.
  • the receiving means 20 is composed of a plate 21 ( Figure 5) and two half-shells 22 ( Figure 6).
  • the plate 21 is in the general form of a substantially rectangular plate 23 approximately the same length as the ammunition 3, and provided at the base with a hollow flange 24 and a finger 25 at its upper edge.
  • a pin 26 serving as a slide for a carriage 27 is fixed parallel to the plate 23 between the flange 24 and the finger 25.
  • the carriage 27 carries a pusher 28 in the form of a U formed by a large branch 29 and of a small branch 30.
  • the large branch 29 is profiled and mounted on the carriage 27 so as to engage in the low position in a cutout 31 of the flange 24.
  • This large branch 29 is intended to repress the ammunition 3 deposited on the flange 24 in the direction of the arrow .
  • the plate 23 also carries a chain 32 mounted around two rollers 33 and 34 and driven in translation by a pinion 35 under the action of a means of rotation 36.
  • FIG. 6 shows the two half-shells 22 fixed to the plate 23 by hinges 37 and joined together by means 38 of fast stapling, of the hook-and-loop type. These two half-shells 22 completely envelop the munition to form a sliding surface during the delivery and are opened using means 38 to introduce the munition there.
  • FIG. 7 and 8 there is shown the mode of cooperation of the chain 32 and the pusher 28.
  • the latter is articulated relative to the carriage 27 along an axis 40 located approximately at the base of the small branch 30.
  • the chain 32 mounted on the rollers 33 and 34, driven by the pinion 35 and possibly stretched by two rollers 41 and 42, carries a lug 43 applied to the internal face of the small branch 30.
  • the lug 43 drives the pusher 28 by application to the small branch 30 from the starting position of FIG. 7 where the ammunition 3 is placed on the flange 24 until the final loading position where the ammunition is introduced into the barrel chamber as shown in FIG. 8.
  • FIG. 9 shows in section the means drive 50 of the chain 32 via the pinion 35.
  • This means 50 generally comprises a shaft 51 for driving the pinion 35, a ratchet wheel 52 driving the shaft 51, a drum 53 driving the wheel 52 and a launcher system 54.
  • the means 50 is fixed to the plate 23 by screws 55 by means of a casing 56 isolated from the shaft 51 by bearings 57.
  • the wheel 52 is fixed to the shaft 51 by a key 58 and rotates in a direction imposed by ratchets 59 fixed to the drum 53 by shafts 60.
  • the drum 53 is mounted on the casing 56 concentrically with the shaft 51 and is rotated by the launcher system 54 consisting of 'a handle 61 and a cord or cable 62 wound and fixed on this drum.
  • the drum 53 is returned in rotation by a spring 63.
  • FIG 10 shows a cross section of the drive means 50 where we see the ratchets 59 fixed by the shafts 60 on the drum 53 meshing on teeth 64 of the wheel 52 to allow the rotation of said drum in the opposite direction and ensure the rewinding of the cable.
  • Each ratchet 59 is held in position on a tooth by a spring 65 fixed by a rivet 66, either to the casing 56 or preferably to a ring 67.
  • the ring 67 is then fixed in a rotatable manner relative to the drum 53 to occupy two positions in which it is held by the ball 68 subjected to the action of a spring 69 (FIG. 9).
  • the role of this ring 67 is to erase the locks 59 to bring them into the position shown in dotted lines shown diagrammatically in FIG. 10, to release the wheel 52 and allow free rotation in both directions of the axis 51 and consequently of chain 32.
  • the chain is also in connection with a non-return means authorizing its movement only in only one direction, that of repression.
  • the means represented in FIG. 11 consists for example of a lever 70 fixed on the plate 23 by a screw 71. This lever is provided with a point 72 which engages between two links of the chain 32 and does not authorize the displacement of the latter only in the direction of delivery of the ammunition represented by the arrow by erasing the tip 72.
  • the chain can be temporarily completely released by acting on the lever 70 in the direction of the arrow F6.
  • the axis 51 of the drive means and the chain 32 are completely released when, in the event of incorrect manipulation, the lug 43 has brought the pusher 28 into an intermediate position and it is desired to bring them back to the low position shown in the figure 7.
  • the slide 8 is in the form of a profile 80 integral with the upright 9 and supporting a raceway 81 as shown in FIG. 12A.
  • the plate 17 of the plate is provided with four rollers 82 engaged on the raceway 81. These rollers 82 are fixed to the plate 17 on either side of the raceway 81 so as to avoid any dislocation and allow the sliding of the device 7 between an initial position in accordance with Figure 1 and a final position in accordance with Figures 2 to 4.
  • the plate 17 is pivotally mounted relative to the slide 8 by l 'through a portion 83 of this slide.
  • the portion 83 is fixed to the rest of the slide 8 by the longitudinal axis 13 ensuring the rotation of the portion 83 relative to this slide.
  • the repression of the ammunition is carried out as follows.
  • the operator after removing an ammunition from the magazine 11 and placing it on the flange 24, closing the two half-shells 22 and bringing the device 7 to the position shown in FIG. 4, actuates the handle 61 which causes the rotation of sprocket 35 and consequently the drive of chain 32 in the direction of arrow F5 (FIG. 7).
  • the lug 43 then drives the pusher 28 by sliding the carriage 27 on the slide 26 until it stops against the finger 25.
  • the continuous advancement of the lug 43 causes the pusher 28 to tip over which completely introduces the ammunition into the chamber of the weapon.
  • the device described above can be applied to any type of weapon mounted in a turret for loading it, but can also be used as an aid for unloading the weapon in a reverse process.
  • the device 7 is put in place as shown in FIG. 4, the ammunition 3 then being engaged in the chamber of the weapon and not in this device and the pusher 28 in the low position. It is then a question of recovering this ammunition which following an incident or stop of shooting is not fired.
  • the ejection mechanism specific to the weapon is actuated at a site equivalent to that of the loading, which causes the ammunition to slide by gravity, which returns to the device 7.
  • the ammunition is then returned to its store according to the reverse process described in Figures 3, 2 and 1.
  • the pusher 28 In the case where the pusher 28 has not returned to the low position, but has remained in an intermediate position, it constitutes an obstacle to the complete sliding of the munition.
  • the chain 32 is released on the one hand by erasing the lever 70, and on the other hand the ratchet wheel 52 by maneuvering the ring 67 which erases the ratchets 59 to bring them into the Position shown in dotted lines in FIG. 10.
  • the chain 32 is then completely free and is driven under the action of the weight of the pusher 28 acting on the lug 43 in a direction opposite to that of the discharge.
