Definitions

  • This invention has for its object certa-n improve-ments in the breech closing mec-hanisni for automatic fire enne having al fixed barrel and a. rotating breech block Where-by a better working and a lQ-llger life of the fire arm and a considerable economy in its construction are obtained.
  • Said improvements consist Substantially in providing on the head portion of the breech bloelA two retaining shoes provided with 1n ⁇ spondingly inclinedV groove provided in the breech bloclr, this latter being thus caused to rotate at a. suitable moment towards its closed position.
  • the plunger is blocked against rotation through a guiding rectilinear ofroove firovided in the cradle in which its shoe slides, and the breech bloc-l: is provided with av lever whereby it is maintained in permanent engagement with the plunger except during the short movement corresponding to the rotation towards the open and ⁇ closed position, said lever being automatically disengaged at the beginning vof said movement.
  • the invention consists substantially inth lcombi,natiche of the following members:
  • a lever connecting the breech block with the plunger its disengagement being aiutomatically edected throng suitable means secured to the Cradle only during the short movement. corresponding to the rotation o the breech block towards its closed and open position respectively.
  • the cradle may he constructed of o rdinary steel requiring'no special treatment as the shoulders on which the breech block shoes act (that must necessarily be of high resistance steel) are obtained in a small detached pieeeand are therefore cheap and ol such forni and size that they will not undergo any permanent deformation during the treatment thus y reducing the losses.
  • the rectilinear guide of the plunger shoe not being subjected 4to a" noticeable pressureas above stated, the cradle may be constructed of ordina-ry steel.
  • -lligure l is an axial longitudinal section, the breech block being in the open position and the connecting lever being engaged in the plungen
  • Figure 2 is a cross section .on line2-2 0f Ege l. ,i
  • Figure 3 is a similar ,Section as Figure 1, the breechblock being shown'when starting its movement towards its closed position and the lever connecting same with the plunger being on the point of disengagement.
  • Figure 4 is a cross section on line 4-4 of Figure 3.
  • Figure 5 is a similar section as Figures engager.
  • the plunger12 is provided at its head portion with a slot 15 in which the lever 8 of the breech block will engage, said lever being pressed by its spring during the whole rectilinear stroke of thev breech block.
  • the firearm works as follows: When firing, the breech block is caused to rotate by the inclined member attached to the, ⁇ cradle, while the plunger which is prevented fromV rotating by ⁇ the rectilinear groove 10, is brought backf wards in respect ofthe breech block (Fig- 15 ( Figures Gand 2) connectingfthe breech .block and the'plungerpto ⁇ each other; theV shoulders 4 of the ures 5 and 1) through the inclined groove 14 breech block 4and bolt, thus connected, will thereupon effectl the recoil stroke, during which the shell is expelled and the feeding forward stroke takes place until the tooth. 9 disengages the lever from the slot 15 of the plunger ( Figures 3 and4)l and the kbreech block, disengaged from this latter, rotates towards its closing position ( Figures 5 and 6).
  • the known means for arming ythe breech block On the shoe 11 of the plunger are provided the known means for arming ythe breech block; saidl operation is made easier owing to the fact that the plunger et'fectsonly a rectilinear motion.
  • acradle having inclined shoulders at its Vforward end, a slidable and rotatable breech-block having shoes formed thereon to engage said shoulders, said breech-block having alcylindricalportion on .its rear end forming' chamber, a plunger slidably mounted in the latter, afspring for pressing the plunger against the bottom of the chamber, a shoe on the plungerl slidablein a recvtili'near gui-de on the cradle andengaging an 'inclined groove in the breech-block, a lever on the breech-block having an arm extending into saidchamb'er, to engage the plungerat the end of the rotation of the breecliblock to 'its open position for connecting the breech-block and plunger, and means on the crandle to move' the lever out of engagement with the plunger at thev end of the forward l y f vstrokeof the breech-block
