Definitions

  • an operating handle for automatic fire arms actuated also manually is described, which is swingably connected to the breech bolt and coopervates with a coupling member, which couples and uncouples the handle with a part of the Vfire arm and especially with the closing spring of the breech bolt, for the purpose that when opening the breech boltby hand the operator is not compelled to stretch the closing spring.
  • the present invention has for its object to avoid this inconvenience by fixingthe barrel automatically when opening the breech-block manually by the said swingable handle, so that the breech-block is openedy on the withdrawal of the breech bolt, which pulls the cartridge case out of the chamber.
