MECHANISM FOR EXTRACTION OF USED CARTRIDGE CASES Russian patent published in 1994 - IPC

FIELD: small arms engineering. SUBSTANCE: extractor has the form of two one-arm levers 7 disposed symmetrically with relation to case. Levers 7 are articulated on axles 6 in slot 5 of ejector head 2. In initial position, when cartridge cases are inserted into cartridge chamber, levers 7 are moved by springs 8 into recess for cartridge case of lower barrel and lock said case against longitudinal movement. When barrel unit is opened, ejector head moves case out of lower barrel by levers 7. EFFECT: higher reliability achieved by eliminating jamming of extractor. 3 dwg
