Abstract

689,427. Smallarms. PROLA, G., and PROLA, C. March 16, 1951 [March 16, 1950; Feb. 22, 1951], No. 6409/51. Class 119 A self-loading firearm with fixed barrel comprises a breech-block 6 and a link 7 connected therewith, the link being adapted to descend during the rearward motion of the breech-block under the actior of an inertia mass 8, which is adapted tc move forward slightly on firing and before the shot has left the barrel and then tc recoil to engage the link and carrying the breech-block into an open position. Fig 1, shows the position of the parts at the moment of discharge. the hammer 20 which has just been released from engagement with a sear 23 by the pull of either one of two triggers 24, 25, being shown in the act of striking the firing pin 55 in the breech-block 6. Upon discharge the mass 8 moves forwardly through a small distance when the gun recoils to compress a spring 65; the energy thus stored is used immediately afterwards to drive the mass rearwardly into the butt 4 against the action of a return spring 18. Fig. 7. As the mass recoils a shoulder 60 in a recess thereof engages with a nose on the lever 7, such engagement serving first to move the lever downwardly from locking engagement with the front faces of fillets 13 in the breech casing and then to pull the lever and thus the breech-block to the rear. The breech-block is guided at 11 in the casing and its recoil serves to re-cock the hammer 20, and also, by extractor 56, to bring the spent case against a fixed stop in the casing cover 3. The stop ejects the case through a side aperture in the cover. this aperture being closed at the time of firing bv a plate 58 pivoted to the breechblock. The mass 8 is temporarily held in the retracted position by the engagement of a catch 39 thereon with the rear end of a cartridge elevator 32. In the meantime a forward extension 27 of the pulled trigger has moved a lug 28 or 29 at the front of a pivotally mounted magazine (not shown). and a fresh cartridge is fed bv the magazine spring on to the elevator, the cartridge moving aside an elevator-retaining detent 36, Fig. 3, during this movement. The elevator is now free to rise under the action of a spring to bring the cartridge into line with the breech. and at the same time to move clear of the catch 39 on the mass 8. The spring 18 then moves the parts 8, 7, 6 to the loading position, a second nose on the mass 8 moving the lever 7 to the locking position during this action. A lever 41, Fig. 7, fulcrummed at 42 in the butt is suitably linked to the mass 8 to effect cocking by hand.
