Definitions

  • Our invention relates to improvements in breech loading firearms and more particularly in firearmshavin'g' a longitudinally movable breechblo'ch with a: cooperating longitudinally: movable extractor for withdrawing spent cartridge 7 shells from the cartridge;- chamber in the barrel.
  • Theknown'fire'arms ofsaid type have many disadvantages. Thus; for example, they require either 'thatthe cartridges are introduced by hand into-the car tridge 'chamber'in the'barrel, or they requi-r the use-of other than-. cylindrically shaped breec'l iblock's which are less dependable in fun'c tion and more difficultto manufacture;
  • the object of our invention is to avoid the said and othei disadvantages and to create a firearmwhi' simple in construction'without' impairing it's dependability;
  • Fig. 2 is the same longitudinal section with the breechblock in locked position.
  • the breechbloek I which contains the firing pin 2 and its driving spring 3 is placed within the easing 4 and may longitudinally move therein forth and back between the loading position shown in Fig. 1 and the locked position shown in Fig. 2.
  • the said casing 5 is joined to the barrel 5 which contains the chamber I I into which the cartridge is introduced before firing.
  • the breechblock I cooperates in a manner known per se with an extractor 6 which is situated in a notch I8 of the casing 4 moving therein longitudinally forth and back between the positions shown in Figs. 1 and 2. To this effect the extractor 5 is provided with a sear I which extends into the longitudinal notch B of the breechblock I.
  • the extractor 6 is equipped with the usual lip 9 which has an inclined front face and cooperates with the rim of the cartridge shell as shown in Fig. 2 withdrawing the shell from the cartridge chamber II after conveyor II] for the cartridge to be introduced into. the. chamber I,I-..-
  • This conveyor Ill in: the lo ading position. of the; arm. as: shown in, Fig, 1 is: situated in front of. the. cartridge chamber. II. andrduring. its. forward-.movement into the firing position shown. in Fig, 2' slips. into the. recess. I3 arrangeciinthe barrel 5-below said chamber II.
  • The: front edgeof. said; recess, It. is chamiered, preferably parallel to. the. inclined. front. face.
  • the extractor I3 is charged bythe spring Iii which also, supports. and; even-may completely replace, the action of; the, usualztriggerspring;
  • This spring 55 holdsand guides thaextractcr-ii inthei casing notch I8. and; assures not only.- the proper actionof the-extractor f, with'its lip 9:, b11t alsozthaceoperation of thesea'r I with'the; breech! block I and with the recess; I 9- in; the striking pin: 21
  • The; said spring is preferably a leaf spring, as. shown and forms, as. saidabove the ⁇ support and uide. for the; extractor it which. is; otherwise freely situated in a notch I9 in the bottom of the casing 4.
  • the extractor 6 is in permanent connection with the trigger I2 whose arm I'I extends into grooves I6 of the extractor.
  • the arm I] is forked and each prong engages one of a pair of grooves IE arranged on each side of the extractor 6.
  • a breech-loading firearm comprising in combination, a barrel, a cartridge chamber in said barrel, a longitudinally movable breechblock, a firing pin arranged in said breechblock, a longitudinally movable extractor cooperating with the breechblock, a lip on said extractor to engage the rim of the cartridge shell and to withdraw the same from the cartridge chamber, the extractor extending beyond said lip and abutting the cartridge chamber in loading position, said extractor extension forming a conveyor for the cartridge to be introduced into the chamber, and a recess in the barrel below the cartridge chamber to receive the extractor extens'ion while the breechblock is locked.
  • a sear on the rear end of the extractor the improvement comprisingv a sear on the rear end of the extractor, a longitudinal notch in the breechblock cooperating with said sear, a recess in the firing pin, said recess being engaged by said sear in cocked position and a trigger mechanism effecting the disengagement of said sear from said recess.
  • a breech-loading firearm according to claim 1 in which the front face of the conveyor part of the extractor and the opposing edge of the barrel are conformingly chamfered, the said chamfered front face of the conveyor and the said chamfered edge of the barrel abutting while the breechblock is in the loading position.
  • a breech-loading firearm in which the front face of the conveyor part of the extractor and the opposing edge of the barrel are conformingly chamfered, the said chamfered front face of the conveyor and the said chamfered edge of the barrel abutting while the breechblock is in the loading position, and the front face of said extractor lip being also conformingly chamfered to abut the said chamfered barrel edge when the said conveyor part is in forward position.
  • a breech-loading firearm comprising in combination, a barrel, a cartridge chamber in said barrel, a longitudinally movable breechblock, a casing for said breechblock, a firing pin arranged in said breechblock, a longitudinally movable extractor cooperating with the breechblock, a lip on said extractor to engage the rim of the cartridge shell and to withdraw the same from the cartridge chamber, the extractor extending beyond said lip and abutting the cartridge chamber in loading position, said extractor extension forming a conveyor for the cartridge to be introduced into the chamber, a recess in the barrel below the cartridge chamber to receive the extractor extension while the breechblock is looked, a sear 0n the rear end of the extractor, a longitudinal notch in the breechblock cooperating with the sear and a recess in the firing pin also cooperating with said sear, a longitudinal notch in the breechblock casing to receive the extractor and to permit its longitudinal movements, a spring pressing
  • a breech-loading firearm according to claim 5 wherein the extractor has at least one longitudinal groove into which engages an arm of the trigger mechanism;
