Indexing reloader of cartridges

A kit for converting a single station cartridge reloader to a multiple station reloader, said single station reloader having a single cartridge holding plunger aligned vertically with a center opening of an overhead die holder adapted for receiving a reloading die, said kit comprising;

• a retrofitting structure including a [base] support plate, a secondary overhead die holder having multiple die holder openings symmetrically arranged around a center opening, a rotatable bushing in the center opening of the secondary die holder , and a one-way clutch mechanism permitting rotative movement of the bushing in one direction and preventing rotative movement thereof in the other direction, and support members supporting the secondary die holder in overhead spaced relation to the [base] support plate, and mounting means for mounting the retrofitting structure to the overhead die holder of the single station reloader,
• a plunger extension and coupling means for coupling the extension axially of the plunger of the single station reloader whereby the extension is protruded through the center opening in the die holder of the single station reloader , a turret adapted to rotatably mount to the top of the plunger extension, and an indexing shaft fixed to the turret and extended from the rotative axis of the turret for vertical sliding movement of the [bushing] shaft through the bushing in the secondary overhead die holder, said shaft having a configured cross section and an indexing portion thereof being twisted spirally around the shaft a determined angle, said bushing having a complementary configuration to allow said sliding and preventing rotation of said shaft relative to the bushing , whereby reciprocal movement of the plunger extension produces sliding movement of the shaft through the bushing and indexing of the turret as dictated by the one-way clutch mechanism.

A kit for converting a single station cartridge reloader to a multiple station reloader, said single station reloader having a single cartridge holding plunger aligned vertically with an opening of an overhead die holder adapted for receiving a reloading die, said kit comprising:

• a support plate,
• an overhead die holder member having a center position and multiple die positions symmetrically arranged around the center position,
• support means supporting the die holder member in overhead spaced relation to the support plate,
• mounting means for mounting the support plate to the overhead die holder of the single station reloader,
• a plunger extension,
• coupling means for coupling the plunger extension to the plunger of the single station reloader to be protruded through the opening in the die holder of the single station reloader,
• a rotatable turret member mountable to the plunger extension, a center position on said rotatable turret member and multiple cartridge holding positions on said turret member symmetrically arranged around the center position of the turret member and corresponding in arrangement to the multiple die openings in the die holder member,
• an indexing shaft extending between the center positions of said members, said shaft being axially fixed relative to one of said members, said shaft having a configured cross section and an indexing portion thereof twisted spirally around the shaft a determined angle,
• a rotatable bushing mounted at the center position of the other of the members, and
• a one-way clutch mechanism permitting rotative movement of the bushing in one direction and preventing said rotative movement in the other direction,
• said bushing having an opening complementary to the configuration of said shaft through which said shaft extends to allow axial sliding of the shaft therethrough and preventing rotation of said shaft relative to the bushing, whereby reciprocal movement of the plunger extension produces sliding movement of the shaft through the bushing and indexing of the turret member as dictated by the one-way clutch mechanism.

An assembly of a single station cartridge reloading structure and a conversion structure converting the single station cartridge reloading structure to a multiple station cartridge reloader;

• said single station cartridge reloading structure comprising;
• a support, a plunger slidably mounted to said support for reciprocal up and down movement relative to the support, an overhead die holder fixedly mounted to the support, said overhead die holder having an opening for receiving a die and positioned in alignment with the plunger, said plunger adapted to support a cartridge and to move the cartridge into the die in the typical single station cartridge reloading operation,
• said conversion structure comprising;
• a plunger extension coupled to the plunger, said plunger extension protruded through the overhead die holder opening, a turret rotatably mounted to the plunger extension to be reciprocated up and down with reciprocation of the plunger, a secondary die holder fixedly mounted to the single station cartridge reloader structure in spaced overhead relation to the turret, a plurality of cartridge holding stations on the turret arranged symmetrically around an upright axis, a corresponding plurality of die receiving stations on the secondary die holder similarly arranged around said upright axis, whereby cartridges placed in the cartridge receiving stations are aligned with dies positioned in the die receiving stations, and indexing means permitting indexing of the turret to successive rotative positions of alignment.
