Definitions

  • the present invention relates to a fire arm the trigger and safety device of .which can easily be put together with the trigger late as an integral whole into the casing o the fire arm and can be removed from 1t 1n the same wa
  • the trigger plate constitutes the bottom of a .frame in which the trigger and safety device 1 s mounted, whereby not only a simple and light construction is attained, but also perfect bearings are provided for all the pivots of the trigger and safety device, and no locking mechanism is needed for these pivots.
  • Fig. 1 is a longitudinal sectional view of one part of a fire arm provided with the new trigger and safety device which is fixed in the fire arm, the hammer being cocked and the trigger locked.
  • Fig. 2 is the same view but in the uncooked position of the hammer and unlocked position of the trigger, and with the trigger and safety device not fixed in the fire arm.
  • Fig. 3 is a partial side view of the fire arm.
  • Fig. 4 is a section taken on line IV--IV of Fig. 1.
  • the trigger and safety device is mounted in the frame 1 which can be pushed into the casing 2 of the fire arm from below.
  • a slide 4 is provided on the bottom of the frame 1, this slide being shiftable in the guides 5 of the frame.
  • the front end of the slide 4 bears on a projection 20 of the casing 2 and revents the front end of the frame from fal in out of the casing.
  • the slide 4 may be shifte by the aid of its cavity 12 which is accessible through the opening 11 on the bottom of the casing 2 which constitutes the trigger plate,
  • the slide can be moved by means of a pointed object for instance a cartridge.
  • the spring 10 may be used,
  • the axle 18 of the hammer 8 is pivoted in 70 the frame 1 and holds the hammer with its middle portion having a square cross section.
  • the axle 18 is provided on its end projecting out of the casing 2, with a handle 19.
  • a slot 23 is provided in the side wall of the casing, said slot being covered by the wall of the frame 1 in such a way that no dust or impurities can penetrate in the interior of the fire arm at this place.
  • a fire arm a casing, a trigger and safety de vice having a hammer and situated within said casing, a frame containing said trigger and safety device and adapted to be easily put into and removed from said casing, the bottom of said frame forming the trigger plate 10 of erm, e slide provided saidN unanime-nd adapted to x the front end of seid e, mother slide provided in the interior of said casing and adapted to x the rear end of the frame, l. hook adapted to x seid hammer inthe cocked position, a s ring situated in the interior of said hook an controlling the movements of said slide fixing the front end of the frame.
