  • a cover partly shown at 25 protects the electrical wiring.
  • the magazine 4 which is inherently mobile and interchangeable, comprises furthermore elements for applying and fixing it tothe weapon.
  • the central space 12 which is left around its axis is used to pass a sliding tube of a draw bar 44 (FIG. arranged in the center of the array of gun cannon barrels 7; when the magazine is aligned with the weapon, this bar engages it and places it in contact with the weapon so that the breeching 5 comes into contact with the barrel supporting block 2 as the guide rollers -l8 slide on rails 45 which are provided for this purpose in the weapon as shown in FIGS. 11 and 12.
  • the ammunition magazine 4 comprises a number of elements whose presence is absolutely essential for firing.
  • FIG. 6 illustrates details of one of the detents 3 which lock the 4 to the block 2 carrying the gun barrels.
  • Each detent 3 has a catch 26 which can pivot about a pin 27. The rotation of the catch is caused by a piston 28' whose rod 28 is connected by a pin 29 to the catch 26.
  • the catch has a slot 35 which receives the pin 29 to convert the axial motion of the rod 28 into a swing of the catch 26 about its fulcrum 27.
  • FIG. 6 the magazine 4 is shown in its locked position.
  • the rounded tip 31 of the catch 26 being applied against a beveled rear face of the breech ring 5, by a spring 30 bearing upon the rod 28.
  • FIG. 7 shows the relative positions of the magazine 4 and the weapon 1 any load.
  • the hole in which it is located has a diameter greater than that of the pin so that the catch 26, in response to the recoil forces, shifts slightly to the rear until its arcuate edge 32 bears directly on a confronting arcuate surface 33 of the supporting body 2, thus relieving the pin 27 of
  • hydraulic fluid under'pressure is introduced via a conduit 36 into a cylinder chamber 34 surrounding the piston 28' as shown in FIG. 8.
  • the pressurized fluid then raises the rod 28 retracting the catch 26 which pivots about its pin 27 to disengage the coasting face of the breeching 5.
  • the empty magazine can then be withdrawn and replaced by a loaded one.
  • FIGs. 9 and 10 schematically illustrate the different phases of the operation of fitting a magazine 4 to its associated weapon in accordance without invention. This operation is carried out entirely automatically, exploiting the mobility of the weapon in two mutually orthogonal planes, more particularly the vertical and horizontal planes. We have found it advantageous to dispose the magazine, preparatorily to; loading, at a location where its axis is aligned with the central axis of the upwards pointing weapon.
  • the gun 37 has been shown provided with a frame 38 designed to receive the magazine 4.
  • the weapon is' carried on its mounting 40 so as to be vertically swingable about an elevational axis 41.
  • a fresh magazine 4 is disposed in an upwardly open pit 43, within a foundation or base, which is overhung by the mounting 40.
  • Flg. 10 illustrates the position which the weapon occupies when a magazine is to be fitted to it.
  • the weapon is arranged vertically above the pit 43 containing the magazine so that its central axis is in line with that of the magazine.
  • Draw bar 44 centered on the axis of the weapon, engages the magazine by passing through the axial hole 12 provided for that purpose. This bar picks up the magazine 4 and raises it until it comes into contact with the block 2 against which it is then held and locked by means of the detents 3 as already described.
  • the magazine (all FIG. 10) is guided by rollers 15 18 mounted on the sides of its casing 6 (FIG. 3) and engaging the rails 45, visible in FIGS. 11 and 12, which are carried by the block 2.
  • the breech ring 5 of the magazine has two openings 48, one circular and the other oval, into which penetrate two pins 47 fixed to the support block 2. These pins ensure that the axes of the various gun barrels register with those of the tubes which contain the rounds of ammunition.
  • the draw bar 44 used to pull the magazine against the block 2 is shown in FIGS. 13A-13D. It has stationary outer shell 49, centered on the gun axis and a sliding tube 50 terminating in a piston 51. The two faces of this piston are subjected to the pressures developed by a hydraulic fluid introduced at a (advance) and R (retract) through two parts 52 and 53.
  • the end of the moving tube 50 carries a catch 54 which can rotate a quarter of a revolution under the control of a motor 55 whose output shaft 56 can adopt two positions offset from one another by an angle of 90.
  • the power used to rotate this motor is hydraulic in the example described, but could equally well be pneumatic or electric.
  • the motor shaft 56 has an extrusion in the form of a square-section tube 57. Inside this tube, but rotatively entrained thereby, there slides a rod 58 which terminates in the catch 54.
  • the axis about which the catch rotates is centred with reference to tube 50 by a bearing 59.
  • the catch 54 whose shape is noncircular, penetrates into the substantially rectangular opening of a socket is fixed to the breechblock 19.
  • the catch 54 Once the catch 54 has entered the socket 60 (FIGS. 13A and 13B), and after it has rotated through a quarter of a turn (FIGS. 13C and 13D), the breechblock is secured to the draw bar 44. It merely requires a further rotation of the catch through a quarter of-a turn to release the breechblock.
  • the feed mechanism according to our invention can be detached and replaced by an operation automatically executed with the help of elements which form part of the weapon proper and act upon other elements arranged for this purpose on the magazine.
  • shape of the magazine and- /or the number of'its ammunition holders may vary.
  • the number of magazines arranged in proximity of the weapon depends upon the location where the weapon is mounted and how it is set up.
  • the weapon will be set up on a vehicle and the holders of the magazine will be arranged concentrically with the weapon axis when the latter is in a vertical attitude.
  • these holders may also be arranged horizontally or at an angle to the horizontal. In this case, when loading takes place, the weapon will be aligned in a corresponding attitude, although this does not affect the basic loading principle.
  • the magazine receptacles can be aligned with the weapon by movement in the horizontal plane.
  • the firing or high-pressure chambers form part of tubes arranged in the magazine. It is possible, however, to separate the chambers from the magazine and make them integral with the gun barrels themselves.
  • FIG. 14 illustrates such an arrangement, the gun barrels 61, 62 being provided at their ends adjacent the support block 2 with high-pressure chambers 63-64 fixed in that block.
  • the ammunition then takes a conventional form, that is to say has shell cases containing a powder charge.
  • the projectiles are marked 65 and 66 and the corresponding shell cases have been designated 67 and 68.
  • the shell cases are fixed by their bases 69 and 70 to a solid component 71 which constitutes the breech block of the weapon. This component is equivalent to the plate 19 of the preceding embodiment illustrated in FIGS. 1 and 3, for example.
  • the assembly of projectiles thus fixed in the breech block 71 is enclosed within a relatively light container 72 constituting the shell of the magazine.
  • the assembly of the latter magazine with the weapon proper is effected in the same manner as described earlier.
  • the whole round of ammunition enters its corresponding barrel, the breechblock 71 being'locked in position through the fixed block 2 which .is part of the weapon.
  • the breechblock 71 comprises all the elements required for firing the ammunition and its profile is such that it enables efficient locking of the magazine to the weapon with the help of detents similar to those marked 3 in FIGS. 1, 6 and 7.
  • a magazine of this kind considered in comparison with the loading mechanism of the preceding Figures, presents an appreciable increase in weight since the high-pressure chambers, which are no longer expendable elements, are integral with the weapon proper.
  • the weapon at any one time had only one leading mechanism, containing as many rounds of ammunition as there are gun barrels to feed.
  • the weapon which may be fired in the form of spaced salvos, it is possible to provide smaller magazines which are adapted to this kind of firing.
  • the weapon is equipped with several small draw bars designed to extract the loading magazines from their respective receptacles and apply them to the weapon, this being done in the same manner as described for a single magazine.
