Definitions

  • FIG. 2 is a side view, partly in section, of the firearm i portion containing the mechanism of the present invention
  • Fig. 3 is a cross-section along line 3-3 of Fig. 2;
  • Figs. 4, 5, 6 are diagrammatic views of a detail of the mechanism in three different positions;
  • Fig. 7 l is a side view partly in section like Fig. 2 of the mechanism according to another embodiment.
  • the cooking mechanism object of the invention, is substantially constituted by a hollow vtubular body 1, provided at its closed front end with a lateral guide groove 2 and at the rear end with two small ears 3 being crossed by a pivot 4.
  • a helical striking spring 5 is contained in tubular member 1, wherein a rod 6 slidable along the axis of the spring-holder member 1 is located.
  • the rear end of the rod 6 is shaped as a piston with a hemispheric recess and therein is seated for turning movement a lugr 7 of a triangularly slotted control member 8, another lug 9 of which is in turn articulated to the striking hammer 10, which rotates around the pivot 11.
  • the barrel-carrying breech piece 31 turns around a ⁇ .pivot 12 on the rear breech piece 30, and another pivot 13 is located in the groove 2 and xed on the barrelcarrying breech piece 31.
  • the hammer is retained in cocked position by the point of a sear lever 14 loaded by a spring 16, resting on the pivot 17, which forces sear lever 14 against hammer 10. Sear 14 is released by trigger 25, 26 urging portion 26a against arm 14a of sear 14.
  • a safety catch 27 cooperates with trigger 25, 26.
  • FIGs. 2, 3 is represented a striker point 18 guided by a cylindrical head 19 integrally connected thereto by a bracket which ensures a regular sliding and furthermore an exact striking in spite of the head and striker point being located in two diierent planes.
  • the weapon partly represented in Fig. 2 is a gun provided with two superposed barrels 31a shown in closed position after release of the right hammer (lower barrel).
  • Fig. 3 shows the striker means 18, 19a, 20a for the second barrel and the members 3, 4 and 8 associated with the second barrel.
  • Figs. 3 and 4 represent the mechanism in the same y When the weapon is opened after release of hammer and 4).
  • Rod 6 has a projecting portion passing through a hole provided in the moving breech 30 and in contact with the release catch lever 24 of the automatic extractor 23 for turning catch lever 24 to release the extractor for operation when the gun is opened.
  • Fig. 7 is partly represented a gun provided with two juxtaposed barrels 31a also provided with the mechanism according to the invention and with two hammers 10, 10a.
  • a rear breech piece in combination, a rear breech piece; a barrel-carrying breech piece pivotally mounted on said rear breech piece; a tubular member having a closed front end and being slidably mounted in said rear breech piece, said tubular member being connected to said barrel-carrying breech'piece for movement with the same; a piston slidable in said tubular member located in the region of the rear end thereof; a spring in said tubular member abutting against said closed end thereof and against said piston; a control member having a slot, said control-member having a forwardly located vcircular lug engaging a corresponding recess in said piston for turnably connecting said control member to said piston, said control member having a rearwardly located circular lug; a hammer pivotally mounted in said rear breech piece for movement between a cocked position and a striking position and having a recess receiving said rearwardly located lug for turnably connecting said hammer and said
