Abstract
A belt-fed, gas-operated, air cooled automatic firearm having a novel mechanism for transferring link-connected ammunition rounds from a novel ammunition magazine to a feed position in an automatic firearm and having a novel sear mechanism including an anti-bounce sear for preventing a bolt carrier from bounding away from the firing position adjacent the firearm barrel.
Claims7
A feed transfer mechanism for an automatic firearm having a receiver housing with a transverse feedway to receive a linked belt of rounds of ammunition, a barrel assembled with the receiver housing, and a bolt supported for reciprocative movement in the receiver housing in coaxial alignment with the barrel and transported by a bolt carrier, the feed transfer mechanism comprising a pawl means supported by the receiver housing for engaging a round of ammunition, an actuator supported by the receiver housing and engagable with the pawl means for moving the pawl means transversely of the center line of the barrel and thereby moving a round of ammunition along the feedway to a position for engagement with the bolt, actuator drive means rotatable about the center line of the barrel for driving the actuator, and feed drive means on the bolt carrier for rotating the actuator drive means.
In an automatic firearm having a barrel and a bolt carrier reciprocatively movable along a path parallel to the center line of the barrel having concentric cylindrical bearing surface, and a feed cover attached to the automatic firearm;
- a feed transfer mechanism comprising a feed drive ring journaled on said cylindrical bearing surface for rotation of the feed drive ring about the center line of the barrel, feed drive means on the bolt carrier for rotating the feed drive ring during predetermined portions of the movement of the bolt carrier, first and second guideways on the feed cover transverse of the center line of the barrel, a slide actuator slidable along the first guideway on the feed cover and engagable with the feed drive ring, pivot means on the feed cover, a feed lever pivoted on the pivot means intermediate of the ends of the feed lever with one of the ends engaged with the slide actuator, a feed actuator slidable along the second guideway on the feed cover and engaging the end of the feed lever opposite the slide actuator, feed pawl means carried by the feed actuator for engaging a round of ammunition to move the round forward to a feed position as the bolt carrier moves away from the barrel and retracting to a position wherein the feed pawl means slides over a next round to be fed as the bolt carrier moves toward the barrel.
