<p>A stuffing tube mounting assembly has an elongated cylindrical barrel (12) with a longitudinal center axis and forward and rearward ends. The barrel has a first barrel portion (14) at the rearward end, a second barrel portion (16) at the forward end, and an intermediate barrel portion (18) in between the first and second barrel portions. The first and second barrel portions have outer surfaces concentric with the longitudinal center axis. The intermediate barrel portion has an outer surface with a center axis parallel to but eccentrically offset from the longitudinal center axis. A hollow elongated stuffing horn (34) has a rearward end detachably telescopically mounted on the second barrel portion. A hollow collar (42) has a longitudinal bore extending therethrough comprised of an eccentric bore portion (50) and a concentric bore portion (52). The concentric bore portion extends around and embraces the rearward end of the stuffing tube mounted on the second barrel portion of the barrel. The eccentric bore portion has an inner surface with a center axis parallel to but eccentrically offset from the longitudinal axis. It rotatably embraces the outer surface of the intermediate barrel portion so that when the collar is rotated in a direction to disalign the center axes of the intermediate barrel of the barrel portion and the eccentric bore portion of the collar, the concentric bore portion of the collar will forcibly bear against the rearward end of the stuffing tube and bind it against the outer surface of the second barrel portion of the barrel.</p> |
