摘要

Improvements in the drive arms by system of articulated levers, with gas drive, characterized in that the weapon comprises an armature, a handle on the armature, a hollow barrel that has a breech, a moving slide on the armor axially to and from the chamber of the gun barrel, a system of articulated levers interengaged between the slide and the armature said system can take a locked position over-aligned slightly above a line joining the outer pivoting axes of the system in the slide and in the armor, because conduit means interconnects the interior of said hollow barrel with a zone immediately adjacent said over-aligned system to transmit gas under pressure from said barrel during firing to said zone to release said system from its over-locked blocked position, and because there is provided a compression element inside the handle, interacoplad or between the armature and the system to normally force the system in an elastic manner towards the over-aligned locked position, upwards.
