  • a spring accumulator 63 the energy content of which is currently replenished by an electric motor 64 working intermittently during the firing serves as the driving motor for the main shaft 62.
  • FIG. 4 Between the transport device for the loading clip and the movable table 54 the device for stripping off the cartridges from the loading clip L is arranged (FIGURE 4).
  • brackets 65 On the bottom of the container two brackets 65 are fixed which form the journals for two shafts 87, on each of which a driving gear 66 and a sprocket wheel 67 are keyed.
  • the driving gears are in mesh with gears 68 keyed to the main shaft 62.
  • axles are fixed on which deflector rollers 70 for two stripper chains 71 are journalled, which consist of endless link chains driven by the sprocket wheels 67. Two of the links of each of these chains are provided with gripper hooks 72.
  • the stripper chains pulling these gripper hooks towards the sprocket wheels 67 are inclined relative to the loading clips contained in the container an angle determined by the resultant direction of movement resulting on the one hand from the movement of the loading strips and on the other hand from the movement of the cartridges in the loading clip undergoing the stripping.
  • a further aperture 83 (FIG- URE 6) is designed for the passage of the cartridges which are moved by the chains 81 of the elevator along the guide sheet metal pieces 84, 85 fixed to the plate 73 towards the weapon, the entry duct of which does not take part in the recoil movement of the weapon.
  • the loading clips L filled for example each with seven cartridges are inserted into the container through the entrance opening 18 in such a manner that the rollers 14 engage into the guide grooves of the rails 19.
  • the insertion of the loading clips is facilitated by the two enlargements 18a, 18b of the entrance opening.
  • the loading clips may be inserted continually even during the firing and either drop down by their own weight or they may be pushed by hand into the container at higher elevation angles of the gun, until they either rest with the longitudinal rib 13 on the helical faces 22 of the guide helices 21 or with their rounded longitudinal edges abut loading clips previously inserted.
  • the sets of cartridges are held in planes directed perpendicular to them.
  • the longitudinal ribs 13 of the loading clips moving downward away from the entrance point 18 when filling the container, force the pawls 26 temporarily out of their path, whereafter the latter are released again and swing under the bias of their springs 28 into the transport and locking position, in which viewed in the direction of movement of the loading clips they lie with their working surfaces behind the longitudinal ribs 13 thereof.
  • the loading clip denoted L in FIGURES 4 and 6 has reached the position in which stripping oif the cartridges begins. It rests with the underside of its longitudinal rib 13 on the start of the helical face 22 of the guide helices 21, while the tips of the projectiles of the set of cartridges contained in it rest on the table 54 and remain guided there during the stripping off movement.
  • the gripper hooks 72 of the two stripper chains 71 lie behind the last cartridge P of the loading clip L Immediately before reaching the stripping off position, that one of the locking pawls 15 of the loading clip securing the set of cartridges which lies nearer to the weapon has been depressed by a device not shown in the drawing, and the set of cartridges has been released for being stripped off.
  • the cartridges are consecutively expelled from the loading clip L in the sequence P P P P by the gripper hook 72 of the stripper chains 71 engaging the last cartridge P and are transferred to the elevator in that they are manoeuvered between any two consecutive gripper hooks 82 of the chains 81 in order to be conveyed by them further to the weapon.
  • the point of transfer of the last cartridge P lies lower than that for the first cartridge P owing to the movement of the loading clip while being stripped a stretch of A3 of the Width of clip.
  • the single-start control helices 51 which turn once during the stripping of one loading clip, release the lugs 56 of the table 54 after the last cartridge has been stripped 01?, so that this table jumps upward under the action of the springs 53 and the lugs abut again the upper start of the threads 52. Simultaneously with the control helices 51 also the guide helices 21 have performed one revolution. The next loading clip L of the pile comes then into contact with the start of the threads of the guide helices 22, and the tips of the projectiles of this new set of cartridges contact the table 54.
  • the pawls may be brought out of engagement with the loading clips, and the sets of cartridges stacked in the container may be lifted out through the entrance opening 18 for the purpose of emptying the container.
