AUTOMATIC SMALL ARM WITH SAFETY DEVICE Russian patent published in 1997 - IPC

FIELD: automatic small arms. SUBSTANCE: retracting handle 2 has projection 3. Installed in barrel extension 1 on axle 15 are safety lever 21 and transmitting lever 17 spring-loaded to each other. Transmitting lever 17 is engageable with sear 9. In all cases when handle 2 with bolt 4 fails to move through full length of cocking, tooth 8 of sear proves to be sunk by bolt 4, shoulder 19 of sear 9 raises shoulder 18 of transmitting lever 17. In this case, shoulder 20 of transmitting lever 17 moves away from safety lever 2 to let it turn under action of spring 22 and position shoulder 23 against projection 3 of handle 2 to prevent its return, and bolt 4 to the extreme front position with possible subsequent shot. EFFECT: higher safety in falling on buttstock and at treading hand off the retracting handle during cocking. 2 dwg
