• fourth guide means for positively guiding a second train of rounds of ammunition along a fourth path which is initially coextensive with said third path which is initially coextensive with said third path and subsequently at a second divergence, diverges from said third path towards said third direction;
• third drive means journaled for rotation about an additional axis for positively engaging each of the links of the second train in sequence adjacent said second divergence for positively driving each such link along said third path through said second divergence;
• fourth drive means journaled for rotation about said additional axis for positively engaging each of the rounds of the second train in sequence adjacent said second divergence for positively driving each round along said fourth path through said second divergence and increasing the pitch between each such round and the next succeeding round as it passes through said divergence;
• control means having a first mode of operation in which said second path is open and said fourth path is blocked, and a second mode of operation in which said second path is blocked and said fourth path is open;
• fifth drive means for positively engaging each such round of said first train in sequence at said increased pitch and passing the rounds of said first train out of said feeder at said increased pitch;
• and
• sixth drive means for positively engaging each such round of said second train in sequence at said increased pitch and passing the rounds of said second train out of said feeder at said increased pitch.

• fourth drive means for engaging each of the rounds of the second train in sequence adjacent said second divergence for positively driving each round along said fourth path through said second divergence;
• and
• control means having a first mode of operation in which said second path is open and said fourth path is blocked, and a second mode of operation in which said second path is blocked and said fourth path is open;
• wherein said control means comprises:
• a first gate means having
• a first disposition wherein said second path is blocked by said first gate means,
• a second disposition wherein said second path is cleared by said first gate means;
• a second gate means having
• a first disposition wherein said fourth path is blocked by said second gate means, and
• a second disposition wherein said fourth path is cleared by said second gate means;
• and
• means interconnecting said first and said second gate means so that when one of said gate means is in its first disposition the other of said gate means is in its second disposition.
