Definitions

  • cartridge loaders in which the cartridges are displaced by a translation motion perpendicular to their axis and contained in the plane of the loaderyare provided with spring elevator devices pusl iingfthe whole" of the cartridges, towards the position where they are taken by the bolt to be thrustinto the barrel.
  • One of the devices most known and used at large comprises an elevator consisting of a simple lever of third kind anteriorly fulcrumed with respect to the loader stressed at an intermediary point of its length by a spring preferably laminated bearing against the bottomcartridge of the loader with an arcuated end, the shape of which has the object to keep as long as possible unvaried the position of the elevators lever against the cartridge while the position of translation of the cartridge varies within the loader.
  • Said device when for instance applied to the Italian repetition gun Mod. 1891 often causes the obstruction of the last cartridge which may be not well held between the curved flanges of the loader.
  • Another device known in different forms of realisation comprises a Nuremberg shear system operated by a spring lodged under the loader. This device has the inconvenience to be very encumberous consequently not adapted for repetition and automaticportable arms.
