A conventional single stage reloader is converted to a multi-station device. The centrally mounted die is replaced by a nut (76) for securing a retrofitting structure (74,78,80) to the single station die holder (22 min ). The nut has a centre opening, and a plunger extension (82) fitted to the plunger (26 min ) of the single station reloader is projected through the nut opening. A turret (50 min ) is mounted to the top of the plunger extension and the retrofitting structure carries a secondary die holder having symmetrically spaced dies (54 min ) and rotatable bushing (63 min ) controlled in part by a one-way clutch (62 min ). An indexing shaft (60 min ) extends from the turret through the bushing and has a multi-sided cross section by which it is slidably fitted to the bushing in a manner that prevents relative rotation. The configured cross section has an axial twist and when forced through the bushing by the reciprocating plunger, causes turning of one or the other of the shaft and turret or the bushing. the one-way clutch allows the bushing to turn in one direction only. The turret (50) resists turning to a degree greater than the bushing (63 min ) resists turning in the direction permitted by the one-way clutch (62 min ). In the other direction the shaft and turret turn and thus sequentially index the cartridges into successive positions relative to the dies in the die holder. |
