Loading machine for feeding a receiver

A loading machine for feeding a receiver, the loading machine comprising:

• a drum cam configured to rotate, the drum cam having a first end, a second end, a first cam path, and a second cam path, the first cam path comprising a first loop around a periphery of the drum cam and extending substantially between the first end and the second end, the second cam path comprising a second loop around a circumference of the drum cam;
• a first track positioned proximate the drum cam;
• and
• a rammer subassembly engaging the drum cam and the first track, the rammer subassembly configured to alternately engage the first cam path and the second cam path, the rammer subassembly configured to move between an extended position and a retracted position as the drum cam rotates when the rammer subassembly is engaged with the first cam path, and the rammer subassembly configured to remain in the retracted position as the drum cam rotates when the rammer subassembly is engaged with the second cam path, the rammer subassembly comprising:
• a first rammer section configured to alternately engage the first cam path and the second cam path, the first rammer section configured to move longitudinally during rotation of the drum cam when engaged with the first cam path, the first rammer section including a first gear engaged with the first track such that longitudinal movement of the first rammer section causes rotation of the first gear, the first rammer section further configured to remain substantially stationary during rotation of the drum cam when engaged with the second cam path, and
• a second rammer section telescopically coupled with the first rammer section and engaged with the first gear such that rotation of the first gear causes the second rammer section to telescopically move with respect to the first rammer section.

• a first track positioned proximate the drum cam;
• a second track positioned proximate the drum cam;
• and
• a rammer subassembly engaging the drum cam, the first track, and the second track, the rammer subassembly configured to alternately engage the first cam path and the second cam path, the rammer subassembly configured to move between an extended position and a retracted position as the drum cam rotates when the rammer subassembly is engaged with the first cam path, and the rammer subassembly configured to remain in the retracted position as the drum cam rotates when the rammer subassembly is engaged with the second cam path, the rammer subassembly comprising:
• a first rammer section configured to alternately engage the first cam path and the second cam path, the first rammer section including a first wing portion extending from a first lateral side of the first rammer section and a second wing portion extending from a second lateral side of the first rammer section, a first gear rotationally mounted to the first wing portion, and a second gear rotationally mounted to the second wing portion, the first gear and the second gear engaged with the first track and the second track, respectively such that longitudinal movement of the first rammer section causes rotation of the first gear and rotation of the second gear, the first rammer section configured to move longitudinally during rotation of the drum cam when the first rammer section is engaged with the first cam path, the first rammer section further configured to remain substantially stationary during rotation of the drum cam when the first rammer section is engaged with the second cam path, and
• a second rammer section telescopically coupled with the first rammer section and engaged with the first gear and the second gear such that rotation of the first gear and rotation of the second gear causes the second rammer section to telescopically move with respect to the first rammer section.
