Definitions

  • 'lhe presentinvention relates to a device adapted to adjust the elevation of machine guns.
  • Such elevation adjusting devices are used during indirect firing or firing in darkness, the machine gun being adjusted for the given firing range.
  • Fig. 1 showing a portion of a machine gun with the elevation adjusting device in side view.
  • Fig. 2 the elevation adjusting device proper, in side view and on a larger scale
  • Fig. 3 a vertical longitudinal section of the same
  • a is a case fitted at top with a recess ZJ into which there is inserted a spirit level (Z pivoted about a pin c and actuated by a spring e. rlhe latter tends to turn the spirit level in such a manner that a steel rail ,f removably attached on the bottom side of the level is constantly held pressed against r the edge of a cam disc t provided with teeth g and adapted to be turned together with a shaft z' journalled in the case a.
  • an arm 7c is attached to the said shaft e' by means of two dogs Z on the rear side of the arm, Figs. 7 and 8, engaging a slot m, Fig.
  • the bottom of the case there are two fixed stops r and s adapted to limit the rotation of the disc 7L to one and the other side, respectively.
  • an arm t carrying a plate e provided with a dove-tailed slot 'a adapted to attach the case to the trigger plate of the gun, the said trigger plate being provided with a lug corresponding to the said dove-tailed slot.
  • the gun When the gun is to be adjusted for firing, it is first adjusted in horizontal position by means of the spirit level which is parallel to the core line of the gun, at which time the pin g of the lever 7c is in the position corresponding to the division line 0. The arm 7c is then turned onto the division line corresponding to the given firing range, and the gun is then adjusted in such a manner that the bubble of the spirit level again becomes central. The gun may then be given the desired elevation, without calculation by means of tables, and the proper elevation may be maintained at any time,
  • rlhe elevation adjusting device of the construction shown, is attached to the left hand side of 'the gun, when during firing the gun is to be given some positive elevation. lf, on the contrary, the elevation is to be negative7 the elevation adjusting device should be placed on the right hand side of the gun, so that the otherwise rearward edge of the case will then be pointing forward.
  • the rail 7 is det-achable. By this arrangement the rail may easily be exchanged for another one either thicker or thinner, when the device is to be used on a gun the height of the sight-line of which differs from the height corresponding to a certain thickness of the rail 7.
