  • Patent number: 6260463
    Abstract: A hand-held tool for loading a primer into a primer socket of an ammunition cartridge case includes an elongate body with a holder for holding a cartridge case with its primer socket in a target position in a priming station. An elongate track on the tool longitudinally guides a rectilinear primer holding strip through the priming station. A reciprocating advancing member moves in advancing and retracting directions, and in its advancing direction engages the primer strip to sequentially align successive primers in the strip with the target position. A detent holds the primer strip against retraction when the advancing member moves in its retracting direction. A plunger is mounted for shifting longitudinally of the body into and away from the priming station to push a primer out of the primer strip into the primer socket of the cartridge. An elongate operator handle is connected to the body for movement relative thereto.

  • Patent number: 5831197
    Abstract: A device and method for loading primers into primer receptacles of a rectilinear primer holder strip. The device includes an elongated track for longitudinally guiding the primer strip through a primer loading station. The primer strip includes a series of longitudinally aligned receptacles, each of which is designed to hold a primer in an interference fit that prevents dislodgement of the primer from the strip. Each primer strip also has a plurality of laterally extending castellations including teeth and depressions that slide on a ledge within the track. The track of the loading device is of substantially the same width as the strip, such that the strip slides through the track. A primer delivery slot in the device delivers a primer into the track, and a pressure application device is positioned to press the primer into a target primer receptacle.

  • Patent number: 5747718
    Abstract: A device and method for loading components into holders used in cartridge case reloading machinery is disclosed. The loading device includes a tray that receives and orients reloading components such as primers. The tray includes a strip receptacle which receives and positions a component holder while components are oriented by the tray and moved into position into receptacles in the component holder. The components are forced into the component holder by manual pressure, a roller, or a lever actuated bar. After the components are pressed into the component holder, the holder may be removed from the loading device and used in reloading machinery.

  • Patent number: 5693905
    Abstract: A device for loading a primer from a priming station into a primer socket of an ammunition cartridge case, includes an elongated track for longitudinally guiding a rectilinear primer strip through the priming station. The primer strip includes a series of longitudinally aligned receptacles, each of which holds a primer in an interference fit that prevents dislodgement of the primer from the strip. Each primer strip also has a plurality of laterally extending castellations or teeth that slide on a ledge over the track, and a reciprocating advancing member on the track has arms that interdigitate with the teeth to move the primer strip forward through the priming station as the advancing member moves in an advancing direction. A detent interdigitates with the teeth to hold the primer strip with a target receptacle in a target position adjacent the primer socket of the cartridge case, while a reciprocating punch pin transfers the primer from the target receptacle to the primer socket.

  • Patent number: 5435223
    Abstract: A cartridge priming device having a cartridge receiver for holding a cartridge to have a primer inserted therein, a primer receiving station for holding a single primer for insertion into a cartridge, a primer reservoir operable to hold a plurality of primers, a passage for directing primers from the reservoir to the primer receiving station, and a guard shiftable between a first position, allowing primers to pass from the passage into the primer receiving station, and a second position in which the guard isolates the primer receiving station from the primer passage to shield following primers from a primer in the primer receiving station. The tool may be a hand-held and operated tool having a swingable handle, with the guard being an arcuate plate member connected to and movable with the operator handle between its first and second positions.

  • Patent number: 5202529
    Abstract: A reloading press that is convertible between different capabilities. The press utilizes a basic structure to which interchangeable conversion sets are individually mounted to provide a reloading press with a capability. To change the capability of the press, one conversion set is interchanged with another. The interchange of the conversion sets permits a user to convert the reloading capability of the press such as from a single station to an indexable multiple station. The conversion sets include top plates for holding a tool or tools, and a shell holder mountable to the ram. Components may be added or interchanged between conversion sets to convert the capability of the press further such as converting from one caliber to another or converting a multiple station press from manual to automatic indexing. The basic structure utilizes a rugged support extending from the base for supporting the interchangeable top plates.
