ROTOR FEED FOR AN AUTOMATIC FIREARM SUPPLIED BY A SINGLE LINK HOOK AND EYE CHAIN BELT

摘要

The cartridge extraction post comprises a central star wheel rotor keyed on a longitudinal shaft whose axis is situated in the vertical plane of symmetry of the assembly of the feed at a level such that the star wheels project into the central upper zone of a transverse passage, formed of two opposite passages. The link-freed cartridges are removed by a pusher operating longitudinally passing through an opening formed in a central zone of the floor of the transverse passage. A fixed support cam in the central zone of the extraction station at the level passed by the back of the links is positioned over at least the fraction of the transverse passage in which the extraction of the cartridges occurs when the cartridge belt passes in the direction F2 reverse to the conventional direction F1 for which the hooks of the links are directed forwardly. The feed lends itself to routeing of the cartridge belt, either in the conventional direction F1 (hooks of the links directed forwardly) for which there is no risk of breakage of the belt by unhooking in the extraction phase, or in the reverse direction F2 (eyes of the links directed forwardly) the cam then resisting lifting and unhooking of the link in the extraction phase under the effect of the upward reaction then exerted on this link which continues to travel in the direction F2 under the action of the rotor thereby correctly driving the following link and the remainder of the belt.
