Definitions

  • Fig. 1 shows a longitudinal section through the gun with its working parts in their foremost position.
  • Fig. 2 shows a similar section with the working parts in their hindmost position.
  • Fig. 3 shows the cartridge insertion mechanism seen in section along the Vline A-B in Fig. 1.
  • Fig. 4 shows the cartridge insertion mechanism seen inv section along the line C--D in Fig. 2.
  • Fig. 5 is a section along the line E-F in Fig. 4.
  • the breech 3 is connected with the barrel extension 2 by connecting linkrods, in the shown example a kneejoint, consisting of a link 14 revolving round a pin 5 in the barrel extension 2 and a second link 6, the ends of which are in turnable connection partly with the breech 3 and partly with the above-mentioned link 4.
  • the end of the link 4 embracing the pin 5 is formed into a toothed segment 7 corresponding with a toothed bar 8 in the lid of the breech box.
  • the toothed segment 7 engages the toothed bar 8 and the kneejoint bends, i. e., the breech 3 opens.
  • the cartridge shell in the cartridge chamber 10 is extracted by the action of the extractor claw 11 and ejected through the outlet openings 13 and 14 in the side walls of the barrel extension 2 and the breech box 12.
  • the ejector device consists of a guide 15 vwhich can be displaced along the side of the breech 3 and during the backward movement of the breech 3 strikes against a stop 16 in the side of the breech box 12 whereby it is pushed forward in relation to the breech 3, the latter continuously sliding backwards whereby the cartridge shell is ejected.
  • the new cartridge is conveyed on this occasion from the opposite side of the breech box 12 by means of a feed block 17 on thebottom of a feed chamber 18 on which the cartridge magazine is fixed. rlfhe feed block 17 swings to and fro by means of 'a two-armed lever 19, 20, which is fixed to the feed block 17 the movement ofthe said-parts being ythereby positively controlled.
  • the barrel extension 2 pushes the arm 19 of the lever outwards, the arm 20 of the same lever swinging into a recess 21 in the side wall of the barrel eXtension 2.
  • the arm 19 again swings into the recess 21, the arm20 being under the action of a spring 22 which continuously pulls it outwards.
  • the feed block 17 is swung to and fro and inserts every time a new cartridge.
  • the striking hammer 24 which isv revolvingly journalled in ⁇ the lower part lof the breech'box 12, is cocked by means of a stop 25 on the sliding contrivance 2 which stop strikes against the striking hammer.
  • the spring 26 of the striking hammer 24, is hereby setto act and its catch 27 clicks in behind a catcher consisting of a revolving pin 28, provided with a notch 29on that side ofthe pin which is turned against the striking hammer-24.
  • the pin 28 is providedrwithan' arm 30 actuated by a spring 31 Awhich turns the pin 28 in such a direction vthat the catch ⁇ 27 is hooked as soon as lit has slid through the-notch 29.
  • the recoil spring 32 is vset to act by a draw rod 33, which is linked to another draw rod 34 revolvingly fixed to the rear link 4 inthe kne'ejoint 3 of the breech.
  • the fore link 6 is provided with a catch 35 'which when the barrel kextension 2 and the breech 3 are in their hindmost positions conditionally clicks in a recess in the other end 36 of a two-armed lever 36, 37 belonging to the trigger mechanism'and being under the action of a spring 38.
  • the gun may be adjusted alternatively for are immediately drawn forward by means of an adjusting mechanism in the Y .form of a revolving pin 41 the side of which 1s provided with a notch.
  • an adjusting mechanism in the Y .form of a revolving pin 41 the side of which 1s provided with a notch.
  • the pin 41 is adjusted so that the notch is turned towards the trigger 39, which in this case can be brought to its hindmost position.
  • l/Vhen the notch is turned away from the trigger 39 the latter in consequence ofthe pin 41 cannot be brought as long rearwards.
  • the gun of a single charge.
  • the trigger 39 is provided with a pawl 42 which when the trigger is pressed backwards raises the arm 37 of the lever 36, 37 so that the working parts are released from the position shown in Fig. 2.
  • the pawl 42 is, however, swung immediately so that the lever 36, 37 can return to itsformer position under the action of the spring' 38 this movement being possible by the means of a. notch 43 in the lever in which the end of the pawl 42enters. 1f
  • the working parts can be moved ⁇ backwards by means of a hand lever 44 which is journalled on the side wall of the breech box and with a thumb 45 engages a recess 46 in the side wall of the barrel extension 2. If after the termina-tion of the firing the working parts have been allowed to pass forward by pressure on the trigger, the gun can be reloaded by means of the hand lever44.
  • the gun is to be provided with the usual elements, such as ad-v breech and slide are4 connected by a toggle V mechanism wherein the link connected with the slide,at its pivot point on the latter, is formed as a gear segment, and a stationary rack is provided in the breech housing, whereby the gear crown rollsalong. theV rack during the movement of the rack relative to the sli e.
  • gear crown and rack are so arranged t-hat, during the first phase of the recoil of the barrel and the last phase of the advance movement, a tooth of the segment is l5 applied against a tooth of the rack and slides along the latter, so that the tooth segment is prevented from rotation.
  • a gear segment formed as a gear segment
  • a stationary rack is provided in a part connected to the 59 breech housing, and wherein the gear crown and rack are so arranged that, during the first phase of the recoil of the barrel and the last phase of the advance movement, a tooth of the rack slides along the latter, so that Q the tooth segment is prevented from rotation.
