Abstract

The loader comprises a well with magazine lips 7 at the opening 3 of the well, and an lifting device 5 mobile and guided in the well under the action of a lifting spring 6, which applies the cartridges 4 against the lips 7 charger. At the posterior end of the cartridges, the interior width of the magazine well 1 is widened beyond the diameter of the posterior end of the cartridges. The cartridges 4 which follow one another in the well are applied alternately with the posterior ends against only one or the other of the side walls 1.1 of the well, the posterior ends of the cartridges being offset laterally and downwards with respect to each other on the cartridge case 4 respectively lower such that, seen from the side and perpendicular to the median plane of the magazine well 1, the axes of the cartridges are parallel.

  relative to each other on the cartridge case

  che respectively lower so that, seen from the side and perpendicular to the median plane of the well

  magazine, the axes of the cartridges are parallel.

  I1 follows that, thanks to the widening of the magazine well at the rear end of the cartridges, the cartridges slide laterally on each other

  in such a way that, with respect to the respective cartridge-

  lower in the well, the rear end of the cartridge is lowered by the amount

  corresponding to the difference in diameter between the ends

  posterior and anterior moths of the cartridges. It's for-

  what, in a projection perpendicular to the median plane

  from the magazine well, the cartridges are oriented parallel-

  together and they keep that

  orientation during their ascent in the well of the tank

  geur. The capacity of the well is therefore the same as for cartridges whose socket has a constant diameter over

the total length of the socket.

  A preferred embodiment of the invention

  is characterized in that the magazine well pre-

  feels, in cross section along the axes of the cartridges, a narrow anterior section and a posterior section

  wider which is attached to it via shoulder-

  profiled elements, the narrow section of the well being only slightly greater than the diameter of the anterior end

  cartridges so that the side walls of the sec-

  The tightness of the well prevents lateral sliding of the anterior end of a cartridge on the respectively lower cartridge sleeve, but that they do not interfere with the inclination of the cartridges in accordance with the lateral offsets of the posterior ends of the cartridges in the

  wide section of the well. It is advantageous that in sec-

  narrow and wide wells the side walls of the well are parallel. In addition, the arrangement is preferably chosen so that the lips of the charger are connected to the side walls of the wide section of the well.

  Figure 4 is a front view of the loader, the front wall of the well being removed. Figure 5 is a top view of the well of the

  charger according to figures 2 to 4.

  Figure 6 is a top view of the cartridges placed in the well, in the direction of arrow VI to

  Figure 2, with removal of all other cartridges.

  Figure 7 is a side view of a cartridge.

  Figure 8 shows two cartridges placed in the magazine well, on the bottom of the cartridges, in the

sense of their axes.

  Figure 9 is a top view of the object of Figure P. The charger comprises a charger well i1 with two side walls 1.1, a front wall 1.-2 and a rear wall 1.3. The loader well 1 is closed at

  the lower end by a bottom 2 and present at the end

  put upper opening 3 for the passage of the car-

  key 4 'respectively upper of the magazine 1 in the weapon (not shown). Inside the well of the loader 1 is movably guided an elevator device 5 which is subjected to. the force of a spring 6. Inside the well of the charger 1, the cartridges 4 are superimposed and guided on the walls 1.1, 1.2 and 1.3 of the well when they are pushed by the lifting device 5 to

  through the well of the charger 1 towards the opening 3 of the well.

  The most advanced cartridge 4 ′ in the row is applied, under the pressure of the device 5, against the lips 7 of the loader which connect to the side walls 1.1 of the well and to the rear wall 1.3 and extend into the opening 3 in such a way that the 4 'cartridge cannot come out of the well

  as in the longitudinal direction of the cartridge as long-

  while its posterior section is still in contact with and guided by the lips 7. One of the cartridges 4 is

  shown as such in Figure 7. It pre-

  feels at the socket 4.1 of the socket a bead 4.2 which protrudes radially from the socket and therefore has a

  larger diameter at the posterior end of the car-

  touches only at the anterior end. In addition, cartridge 4

  includes in the socket a transition zone 4.3 to widen

  conical sliding between the anterior and posterior ends

  the cartridge. The anterior end of the car-

  key is flattened because, according to the example shown, these are plumb cartridges. The diameter of the anterior end of the cartridge is designated by the reference r; that of the transition zone 4.3 by the reference R 'and that of the posterior end formed by the bottom bead 4.2 by the reference R. The length of the cartridge

  4 is designated by L and the distance between the transition zone

  tion 4.3 and the bottom of the cartridge 4.1 by LO.

  The well of the magazine 1 widens from its interior width b at the anterior end of the cartridge To an interior width B at the rear end of the cartridge, the interior width B at the anterior end of the cartridge substantially corresponding to the diameter 2r of the front end of the cartridge, while the internal width B at the rear end of the cartridge is greater than the diameter 2R of said rear end. The successive cartridges 4

  in the well of the charger 1 are therefore applied!

  with the posterior ends against one or

  the other of the two side walls of the well 1.1. Extremes

  posterior moths of the cartridges are then shifted on the sleeve of the cartridge 4 respectively lower in the well not only in the lateral direction, out of the median plane 1.4 of the well, but at the same time also slightly down, namely Just enough so that , in the side view perpendicular to the median plane 1.4 of the well shown

  in FIG. 2, the axes of the cartridges 4.5 extend parallel-

  parallel to one another, while in the view according to FIG. 6 perpendicular to the latter, said axes form an angle y between them. When the cartridges 4 are

  moved up in the well towards the west

  verture 3, they do not change orientation, except

  tion of the most advanced cartridge 4 ′, which is applied against the lips 7. In fact, the lips 7

  are shaped in such a way that they center the

  anterior key 4 'applied against them in the opening

  ture 3, over its entire length relative to the median plane 1.4 of the well, without the cartridge 4 ′ still being in contact with one of the side walls 1.1 of the well, as

  this is clearly shown in Figures 3 and 5.

  In detail, in the cross section of FIGS. 4 and 5, the well comprises a narrow anterior section 1a extending along the axes of the cartridges 4.5 and having an internal width b indicated in FIGS. 8 and 9, as well as a section posterior wide the inner width B which is connected to it by means of profiled shoulders lb. The width b of the narrow section la of the well is only slightly greater than the diameter 2r

  from the anterior end of the cartridges. The side walls

  1.1 sections of the narrow section do not interfere with the

  clinching of the cartridges 4 from the angle y, but on the other hand they prevent sliding of the anterior ends of the 2 cartridges on the base of the respectively lower cartridge. On the quantitative level, it appears from the figure

  for the mutual lateral offset D of the posterior ends

  of the cartridges: D2 = (R +,) 2 4r2 and for the interior width B of the wide section e:

B = 2R + D + 2R + V (R + R ') - 4r2.

  For the internal width b of the narrow section la, it appears from FIG. 9:

b = 2r + d = 2r + DL '/ L.

  To ensure additional guidance of the anterior cartridge 4 'during its transfer from the well, having regard to the internal width b slightly greater than the diameter 2r of the cartridges, provision is made to connect to the side walls 1.1 of the narrow anterior section. the of the well of the opposing guide tongues 10 whose spacing is reduced, with respect to the width b of the narrow section la, to the diameter 2r of the anterior end of the cartridge. The spacing X between the guide tabs 10 and the lips 7 of the magazine, in the longitudinal direction of the cartridges, is at least equal to the distance LO between the transition zone 4.3 of the socket and the base of the cartridge 4.1, indicated in Figure 7. The lips 7 of the loader are connected to the side walls 1.1 of the wide section lc. Furthermore, the side walls 1.1

  narrow and wide sections 1a, 1b of the well extend parallel

together.
