    Abstract: Ammunition reloading apparatus includes a shell case support for holding a shell case, a container spaced above the support for holding shell loading material to be placed in a shell case during reloading, and an elongate charge bar underlying the container having a charge opening therein. The bar is mounted for movement between a first position in which the opening underlies the container to receive a charge of material and a second position where the material may be released to an underlying shell case. Control mechanism is operable to sense the presence or absence of the shell case on the support when the charge bar is in its second position. The control mechanism prohibits release of material from the charge opening when a shell case is absent and permits release of material to be dispensed to the shell case when a shell case is present.

  • Patent number: 5133240
    Abstract: A method and an apparatus for producing a large-caliber ammunition unit including a combustible or partially combustible propelling charge casing and compacted or partially compacted propelling charge powder, to increase internal ballistic performance. It is known to partially or completely compact or compress the propelling charge powder in a cartridge casing. However, such methods generally cannot be employed for ammunition including a combustible or at least partially combustible propelling charge casing because of the lower strength of the relatively thin-walled combustible casing material, as this would lead to deformation and/or to reduced loadability of such cartridges.

    Abstract: Multiple measuring cavities of given and identical volume are formed in a base. Each measuring cavity is elevated from the base by a protrusion with tapered sides. Pulverulent or granular material is then poured into the cavities filling them to overflowing. The excess material flows down the protrusions and drains through holes in the base. The surfaces of the base present sharp edges to the flow of medium to eliminate its collection other than in each measuring cavity. Cartridges to be filled are inverted and the cartridge mouth is placed over each protrusion and its full measuring cavity. The cartridge mouths come to rest on the tapered sides of each protrusion. A cartridge retaining cover made to fit over and align with the base is placed over the cartridges. The cover holds the cartridges is contact with the sides of the protrusions, then, the cover and base are grasped and turned over as a unit, emptying the contents of the measuring cavities into the cartridges.

The probes signal the level of powder in the cases by rising out of the holding plate to proportionate heights. The improvement involves the use of magnetic probes which, upon encountering low or missing powder charges, actuate magnetic latches to prevent the loading plate from being separated from the holding plate.
