1278079 Cartridge belt guiding arrangement WERKZEUGMASCHINENFABRIK OERLIKEN-BUHRLE AG 29 Aug 1969 [4 Sept 1968] 43245/69 Heading F3C A cartridge belt feed duct for guiding a cartridge belt in its passage from a magazine to a weapon mounted for elevation, comprises first and second relatively rotatable ducts 10 (50, Figs. 1, 3, not shown) connectible to the magazine and weapon respectively, a rotatable disc 14 drivably connected to the second duct having an aperture 43 aligned for the passage of the cartridge belt and a flexible guide rail 44 in the first duct and connected at one end indirectly to the disc the profile of which rail is variable such that the part of the guide rail 44 adjacent the aperture 43 is always arranged in use substantially parallel to the rear surface of the cartridges being fed through the aperture for positioning of the disc corresponding to elevated positions of the weapon. The disc 14 may be connected to the second duct through a reduction gearing for rotation therewith. The guide rail 44 is pivoted at one end on a bell crank lever 20 pivoted on a pin stationary with the duct 10 and at the other end on a pin 27 also stationary with respect to the duct 10. The lever 20 is rotated by a rod 22 pivoted to the disc 14. In its bending the guide rail 44 is braced against a pin 18. The disc is provided with guide surfaces for the cartridge belt projecting into both ducts at the upper side of the aperture and two rollers 37, 38 in the duct (50) guiding the side and rear faces of the cartridges respectively.
