ABSTRACT:
Cylindrically arranged barrels include feeder rods connected to a wobble plate for reciprocally moving shells into a firing position. A back pressure seal sleeve may be positioned on the feeder rods. The sleeves include a forwardly tapering wall thickness whereby combustion pressures press the tapered wall sealingly against the feeder rods. An alternative sealing arrangement includes cut-off pins for each barrel which reciprocate transversely of the barrel in timed relation with the feeder pins. A cam rotates with a power shaft connected to the wobble plate and a nonrotating housing is positioned on the cam and is connected through linkage elements to the cut-off pins.
