Definitions

  • iii-invention 4 relates to an automatic pistol in which the reaction ofthe gunpowder as .pressure and a spring force counter-actnig the as pressure act automatically at the 3 iiilngo the pistohthus effecting feeding 1n o'fa new cartridge, cocking of the pistol, firing off, and ejection of the empty cartridge.
  • Fig. 1 illustrates a vertical longltudinal s 'ectionfofthe automatic pistol accordlng to theinvention.
  • Fig.f2 illustrates the automatic pistol in f side-elevation.
  • Fig. illustr'ates the cocking parts ofthe automatic -pistol in horizontal longitudinal section.
  • the cartridge case 1 which is either a prismatic tube or a round container, 1s 1.,. pishedfinto the feeding aperture in the butt- *5 end 40,th'e cartridge case 1 being retained in the feeding aperture by means of a notch in the side ofthe case'and a corresponding latch 3 pivoted in the butt-end and acted by afspring.
  • a fceding spring in the cartridge case' '1 effects the feeding in of the cartridge inthe usualfmanner.
  • The' resetting sV ring 8 extends into a centric 'UO bor'43fiix'the ocking' lunger 4, thus making the cock shorter. t the commencement of theirin'g the cocking bolt 5, fitted into the butt-end 4,V is pulled backwards.
  • T'he mantle piece 33 of the locking cylinder 25 may be furnished with a small hole, through which air is let into the cylinder.
  • the e'ect of the vacuum brake 75 may be varied by means of adjusting the size of the hole.
  • the forward end 16 of the locking plunger 4 pushes the cartridge from the mouth of the cartridge case 1 into the cartridge chamber 17 andnally the firing 80 needle 18 at the foremost end of the locking plunger 4 strikes the percussion cap of-the cartridge, thus effecting the firing off of the cartridge.
  • the empty cartridge and the locking plunger 4 are forced backwards by reaction of the gunpowder gases.
  • the eX- tractor 19 pulls the cartridge until the ejector notch 20 in the opposite side ejects the cartridge through the discarding aperture 21.
  • the cartridge channel 50 In the foremost part of the lock and above the mouth of the cartridge magazine the cartridge channel 50 is located. In this channel 'the cartridges and the front end of the bolt 4 move successively.
  • the guiding of the empty cartridge in the said'channel 50 is se- E cured by the wall of the channel being provided with a special guiding bar 51 the inner edge of which is parallel or only slightly oblique to the longitudinal axis of the channel and located from the said axis substantialy the same distance as the maximum ra- ⁇ dius of the cartridgechamber 17.
  • An automatic firearm operating by l means of reaction pressure comprisingJ a cartridge chamber a cartridge channel 'sosed adjacent said chamber, said channel ing pro'vided with a lon 'tudinal guiding bar, the inner e e of whic I is substantially parallel to the axis of said channel, said inner edge also being disposed at substantially the same distance from the axis of said channel as the radius ofl said cartridge chamber.
  • An automatic firearm operating by means of the reaction pressure comprism a cartridge chamber, a cartridge channel 1sposed adjacent sald chamber, an extractor positioned in said channel a lon 'tudinal llxiding bar also positioned in sai channel 'ametrically opposite to said extractor, the
  • said inner edge of said guiding bar extending substantially parallel to the -axis of said chan- '40 nel and the 1nner edge of said bar also being disposed at substantially the same distance from the longitudinal axis of said channelv as the radius of said cartrichamber.
