Definitions

  • the object of the present invention is to provide a device which answers all purposes indicated above.
  • the device according-to the invention is'characterized bythe actthat the trigger is arranged inthe plunger-like percussion hammer and by a particular formation of the latter which permits the arrangement of all members, ⁇ with the exception of the trigger shaft, in a single bore of the breechblock.
  • the breech mechanism is closed whichmaysbe-elected by simply disengaging the protecting cover which serves as an abutment for the main spring andf is 4bayonet-like arranged inthe breech' member.
  • a construction robviates a particular recess in the breech memberfor the reception of' a lock member.l arranged separately from thepercussion hammer.
  • the accompanyingdrawing shows'by way of example a device according to the invention as applied to a breech mechanism on a gun.
  • Figure 1 shows a: part: sectional view of the primer lock with the triggerV in the position of rest
  • Figure 2 illustrates infpart sectional elevation the primer lock. in. theposition in which the trigger lever isfcompletely tilted, that istosay the main spring istensioned to a maximum
  • Figure 3 is a part sectionallview of the primer lock in the releasedf position
  • Figure 4 is a part sectional elevation of the device according to the invention showing 338,600, ⁇ andinGermany February 20, 1928.
  • FIG. 5 is a cross section on line I--I ⁇ of' Figure l looking from the point of the percussion hammer
  • Figure 6 is a cross section also on line I-'I of Figure l, but looking in the directionrom the butt-:end of the percussion hammer
  • Figure 7 is a bottom plan View ofthepl'unger
  • Figure 9 shows elevationV of the trigger member and Figure l0 is aview, of the front-spring abutment looking from ⁇ the point of the percussion hammer.
  • the cylindrical; plunger body b'- of. the primer lock carries'atits front face ⁇ the point b1 of thepercussionhammer and ⁇ is slidably arrangedl in a bore ai of the breech mechanism a provided in the prolongation or ez;- tensionY of the axis of the bore of' the gun.
  • Rotation o1E the longitudinally movable plunger I) is prevented by a nose Z22 slidingly engagingv a corresponding groove ⁇ of the wedge member.
  • a part ofthe plunger Z) is providedwith: a bore for the reception of the main spring f.
  • a cover a2 connected bayonet-like to the breech member serves as fixed rearward abutment for the spring f.
  • the front end of-thespring fbears against a disc 0 arranged'with a certain play in the bore b4 of the plunger b;
  • the disc e carries at its lower part an eye c1 snugly litt-ing a longitudinal slot fof the plunger body
  • hammer carries a cam-c3 which-extendsthrough a bore bs ofV the plunger vbody b and bears against the slide ⁇ - face g1 of the trigger gthe pivot pinv g2 ofA which is rotatably arranged in the plunger body b. y As the main springis inserted? under a certain tensiointhe trigger g, positively engagesthacam ⁇ 03; of the disc c Meer d bled.
  • the trigger shaft is under the action of a torsional spring not shown in the drawing by which, after re'- Vlease of the' trigger-"lever, this lever and -therefore the trigger shaft also are'returned to the original position; When during this rotational movement the trigger shaft occupies the position shown in Figure 4, the stop surface.
