Abstract: The cartridge case preparation rotor device trims cartridge cases to overall length correctly and further prepares them for reloading. The rotor holds multiple case preparation tools so that the user may conveniently and precisely apply them more squarely to a turning cartridge case. The rotor slides and turns on a rod mounted opposite a variable speed motor fitted with a chuck turning a case holder. Flexibility of the rod and oscillation of the rotor permit each tool to follow case eccentricity. An enlarged grip on the case holder simplifies installation and removal of cases. A neck cleaning tool cleans the inside and outside of the case neck simultaneously. The rotor may be slid along and turned upon the rod manually, or the motor and rotor can be mounted on a progressive press. The pushbutton control switch can be pressed by hand, or set on the floor as a foot switch.

Abstract: A shell plate for being indexed in angular steps is on a carrier which is, in turn, mounted to the upper end of the reloader ram. Indexer rod engageable elements such as cylindrical equiangularly spaced apart pins project downwardly from the bottom of the shell plate. An indexer rod is carried in the shell plate carrier. When the ram is driven to nearly its lowermost position, the manual operating lever is near the end of its swing at which time it abuts the indexer rod for the latter to engage one of the pins to rotate the shell plate. The indexer rod is retracted and reset by having it slide down a guide track from the uppermost position of the ram and the guide track is angulated in part to be engaged by the rod and retracted. The reloader is distinguished by indexing the shell plate only when the ram is within a few millimeters of its lowermost limit.
Abstract: The present invention provides an automatic feed mechanism for the assembly of ammunition. Ammunition is assembled in the feed mechanism by the joining of bullets with their respective shell casings, one at a time. The automatic feed mechanism is utilized in conjunction with a progressive reloading press. The automatic feed mechanism comprises a replaceable feed tube having a precise bore. The bore is designed to accommodate the free fall of a single bullet of a given caliber for precise alignment with a shell casing of the same caliber. The precision of this alignment stems from the precise bore tolerance for a given bullet caliber, with the union of the bullet and the shell casing only under the influence only of gravitational forces. Should it be desired to join a bullet of another caliber with a shell casing of the same or different caliber, the feed tube is easily removed and replaced by one having the proper dimensions and internal bore to assemble the new ammunition.

Abstract: An improved shell reloading machine incorporating in addition to the essential features of utility convenience and low cost, an effective means for the prevention of primer cap detonation which might otherwise occur due to improper alignment of the primer feed mechanism.
Abstract: In order to increase the efficiency and reliablility of shotgun shell reloader apparatus of the type in which an empty shell is entered and removed at a single entrance/exit station and the shell is transferred in a circular path from station to station at which the several reloading operations are performed sequentially, an accessory ejection spring is employed to automatically eject a completed shell as it enters the entrance/exit station (thus eliminating the necessity for manually handling a completed shell at the entrance/exit station) and a spring pad including a magnetic member is employed at the priming station to positively receive and emplace a new primer just prior to the repriming operation (thus eliminating instances of incorrect orientation of the new primer with respect to the deprimed shell into which it is to be seated during the priming operation).
Abstract: To enable a shell to be automatically primed during operation of a loader, the primers are mounted within a chute to fall by gravity to an opening where a lever is pivoted by a cam as the shell carriage of the loader moves in a vertical direction within the frame of the loader. The motion of the lever moves one of the primers from the chute into position underneath the shell carriage for insertion into the shell casing as the carriage moves downward against the base of the loader frame. The lever arm is spring-biased into position underneath the rim of the holder and contacts a cam mounted to move up and down with the carriage upon the actuating of the loader handle by an operator. The shell is deprived during the upward movement of the carriage and the downward movement.

Abstract: An ammunition case reloading press is based on an O-frame die cast from a low strength metal. A case carrying ram is driven reciprocably through a bottom member of the O-frame toward and away from a die in a top member. A compound lever system is actuated by a manual operating arm to drive the ram. A stop prohibits the links of the lever system from toggling into dead center position to thereby limit the stress of the O-frame. The operating arm is designed so it will flex to signal the user that unnecessarily great resistance is being offered and that the die should be adjusted relative to the ram to reduce the stress. The operating arm and lever system pivots are askew to a vertical plane passing through the frame so the arm swings clear past the side of the O-frame and so there is a clearer line of sight to the opening in the O-frame where the cases are placed on and removed from the ram.
