Definitions

  • the invention eliminates this drawback by allowing the disengaging of the handle and the closing spring only on such parts of the stroke or path of the breech bolt, on which this disengagement is intended, for instance on the part on which the breech bolt is closed, .or on parts on which the disengagement facilitates the dismo'unting and mountingof the gun.
  • Fig. '1 is a longitudinal sectional View of the operating handle device. 7
  • Fig. 2 is a cross section taken on line 11-11 of Fig. 1.
  • Fig. 3 is a top plane View of the same part of the gun showing the operating handle in section.
  • Fig. l is a partial top plane view of the breech casing after removing the operating handle.
  • the operating handle 1 is pivotally connected with the breech bolt 3 by means of a pivot 2.
  • the coupling arm 7 Around the pivot bolt 2 is pivotally mounted the coupling arm 7 the hook of which engages in a known manner with the head portion 18 of the closing rod, the latter being under the action of the closing spring 12.
  • the breech bolt during its backward movement stretches the closing spring 12 by means of the coupling arm 7, in such a manner that the closing spring pushes the breech bolt into its closing position, when the recoil movement ceases. Together with the recip- This engagement is, however, broken rocating movement of the above mentioned parts, the handle 1 and the arm 7 move also to and fro.
  • the hook is fitted according to the invention with projections a3, and at the same time a guide for the arm 7 arranged in the casing 21 is fitted with strips located above the path of the projections 23.
  • the strips 22 are not present resp. are interrupted on such parts of the projections path on which the disengagement .is intended, for inst. on the part on which the breech bolt is fully closed, so that the hook 01"- the arm 7 can be lifted at this place whereby it is kept by the strips at all other places in the guide, so that the strips prevent the disengagement.
  • an automatic fire arm a breech bolt, a breech closing rod, an operating handle, a pivot bolt adapted to connect pivotally said handle with the breech bolt, a coupling arm .pivotally mounted onsaid pivot bolt and having a hook adapted to engage and disengage with the closing rod, a guide for the coupling arm arranged on the breech casing, projections fitted on said hook, strips provided on the said guide and arranged above that part of the path of said projections, on which-said coupling arm is intended to remain in engagement with the closing rod.
