Definitions

  • the technical field of the present invention is that of ammunition loading devices in the chamber of a weapon mounted in a tank turret.
  • the barrel loading is made by a servant who loads the ammunition into the weapon either manually or using a loading shovel. But when the turret is equipped with a load automatic, there is no longer a servant and the smallness of the available space makes it impossible to charge manually the weapon. In addition, at the end of the race, the ammunition must receive sufficient energy to introduce it into the gun room. It is therefore essential to be able to load the weapon in case of automatic loading failure and more generally to have a loading device usable in all circumstances.
  • the purpose of the present invention is to provide a rustic, space-saving loading device, reliable and easy to use.
  • the invention therefore relates to a device for manual loading of a cannon integrated into a turret armored vehicle, consisting of a means of receiving ammunition secured to the turret basket, a chain closed operated by manual drive means integral with the receiving means, characterized in that it includes an ammunition delivery pusher integral with a carriage in an articulated manner, mounted sliding on a slide fixed to the receiving means, to ensure a displacement of the ammunition greater than the travel path of the carriage when it is driven by the closed chain.
  • the means of reception is secured to a slide ensuring storage position from which the ammunition is taken and a loading position in line with the barrel.
  • the reception means consists of a plate and two half-shells articulated with respect to it.
  • the plate consists of a plate substantially rectangular fitted with a flange at the base of which the ammunition is in support.
  • the carriage slides on a slide fixed to the plate parallel to this one.
  • the pusher is in the form of a U-shaped part, a large branch is supported on the base of the ammunition and whose small branch cooperates with the chain to repress the ammunition.
  • the closed chain is driven in translation around two rollers each arranged 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 road driven in rotation and meshing on a pinion drive shaft, said wheel being driven in rotation by a drum actuated by a means constituted a cable and a handle and subjected to the action of a spring.
  • a motor means which consists of a ratchet road driven in rotation and meshing on a pinion drive shaft, said wheel being driven in rotation by a drum actuated by a means constituted a cable and a handle and subjected to the action of a spring.
  • a very first advantage of the invention lies in the the device ensures transport and transfer generally heavy ammunition in a location ergonomically inaccessible.
  • Another advantage is the possibility to print 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 integral with the turret belt 10.
  • a munition 3 is manually removed from the magazine 11 that we place on the receiving means of the device 7 as shown in Figure 1 and deploy the slide 8 along the arrow F1 .
  • 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 F3 at the loading site shown in FIG. 4 and the device 7 tilted around a point of articulation 13 along the arrow F4 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 F 5 .
  • 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.
  • Figure 6 shows the two half-shells 22 fixed to plate 23 by hinges 37 and joined between them by a quick stapling means 38, of the type Velcro strip. These two half-shells 22 completely envelop the ammunition to constitute a sliding surface during discharge and are open using means 38 to introduce the ammunition.
  • FIG. 9 shows in section the means drive 50 of chain 32 through the pinion 35.
  • This means 50 generally comprises a shaft 51 pinion drive 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 via 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 driven in rotation by the launcher system 54 constituted a handle 61 and a cord or cable 62 wound and fixed on this drum.
  • the drum 53 is recalled in rotation by a spring 63.
  • the handle 61 is driven the pinion 35 which ensures sequential drive of chain 32.
  • Figure 10 shows a cross section of the medium motor 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 rewind the cable.
  • Each ratchet 59 is held in position on a tooth by a spring 65 fixed by a rivet 66, or to the casing 56 or preferably to a ring 67.
  • the ring 67 is then fixed so rotatable 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 clear the locks 59 for them bring in 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 as a result of the chain 32.
  • the chain is also related to a non-return means allowing its movement in only one direction, that of the backflow.
  • the means shown in Figure 11 consists for example of a lever 70 fixed to the plate 23 by a screw 71.
  • This lever is provided with a tip 72 which engages between two links of the chain 32 and does not allow the displacement of the latter only in the direction of delivery of the ammunition represented by the arrow F 5 by erasing the tip 72.
  • the chain can be temporarily completely released by acting on the lever 70 in the direction of the arrow F 6 .
  • Axis 51 of the drive means and the chain 32 are fully released when a false handling the lug 43 brought into a position intermediate pusher 28 and we want them return to the low position shown in Figure 7.
  • the slide 8 is in the form of a profile 80 integral with the upright 9 and supporting a path bearing 81 as shown in FIG. 12A.
  • the plate 17 of the plate is provided with four rollers 82 in taken on the raceway 81. These rollers 82 are fixed to the plate 17 on either side of the path bearing 81 so as to avoid any dislocation and allow the device 7 to slide between a initial position according to FIG. 1 and a position final according to FIGS. 2 to 4.
  • plate 17 is mounted swivel relative to slide 8 by 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 with respect 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 the pinion 35 and consequently the drive of the chain 32 in the direction of the arrow F 5 ( Figure 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 tipping of the pusher 28 which completely introduces the ammunition into the chamber of the weapon.
  • the device described above can be applied to all types of turret-mounted weapons for the loading it, but can also be used as aid for unloading the weapon in a process reverse.
  • the device 7 is put in place as shown in Figure 4, the ammunition 3 being then engaged in the chamber of the weapon and not in this device and the pusher 28 in the low position. he it is then a question of recovering this ammunition which following a incident or stop of fire is not fired.
  • the ammunition is then brought back to his store in the reverse process described in Figures 3, 2 and 1.
