  • Publication number: 20040025677
    Abstract: Reloading apparatus for reloading ammunition shell cases includes a shell case holder having a pair of yieldably biased gripping fingers positioned to engage and hold the rim at the base of the shell case. A resizing die mounted for sliding about a shell case has a lower rim adapted to engage and move the holding fingers away from engagement with the rim and thus provides substantially full length case resizing. Ejector mechanism in the resizing die is operable to urge the shell case out of the die and hold it in position to be regripped by the holding fingers as the die and support are moved away from each other.

  • Publication number: 20040025678
    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.

    Abstract: The present invention is an apparatus for installing primers in ammunition shells, comprising a primer holder having walls defining a pocket opening to an upper surface of the holder for receiving a primer. The pocket has a diameter slightly smaller than the diameter of a primer so that there is an interference fit between the pocket and the primer sufficient to prevent the primer from being inadvertently dislodged from the holder during shipment, handling or use of the holder. The holder has a hole extending from a bottom of the pocket to a bottom surface of the holder for receiving a pin which pushes the primer out of the pocket and directly into a shell in response to relative movement between the holder and the pin. The holder preferably is disk shaped and has a plurality of pockets. The invention further comprises a shell reloading machine which utilizes the new primer feed system.

  • Patent number: 5040449
    Abstract: In a shotgun shell reloader, a manually operated lever drives a carriage reciprocally on a central post for shotgun shells mounted to the carriage to engage with reloading tools arranged on a support which mounts to the upper end of the post. A circular shot plate mounts to the carriage and has a central bore for surrounding the post. An indexer member mounts in the bore of the shell plate and surrounds the post. The indexer has a helical groove in its bore which rides onto a pin extending radially from the post when the carriage is beginning to be raised so that the indexer, which is engaged with the shell plate at that time, turns the shell plate through one angular increment so that a shell on the plate will be presented to tools on the tools support successively to perform the reloading process. A powder bar and a shot bar are mounted to the top of the tool support for moving under a hopper which has chambers for powder and shot.

    Abstract: The adjustable powder measure is designed to effect the reloading of firearm cartridge cases. It comprises a main body in the form of a transparent powder container 6 with a transparent center tube 7 able to slide inside the container and powder contents. Measuring and dispensing is viewed through the transparent components. The friction fit plug 8 is adjusted to obtain the desired volume by insertion of a graduated rod 10 into the bore of the center tube. A reprimed cartridge case 1 is attached to the transparent pliable end tube 2, the powder measure being held vertically with the cartridge case at the top. The center tube is drawn below powder level, filling the measuring cavity above the friction fit plug. The center tube is then pushed through a sealing washer 4.

A probe is mounted on the lower end of the plunger which contacts the powder deposited in the cartridge shell, wherein the probe lifts the plunger so that the groove in the plunger may receive the ball upon the presence of a proper amount of powder so the sleeve can slide upward into the housing allowing the cartridge to enter the housing. Preferably, the powder level sensing device is adapted to be mounted onto existing reloading press frames, particularly the progressive reloading press frame. Also disclosed is a method for adjusting the powder level sensing device to accommodate various cartridge shells and desired powder levels.

  • Patent number: 4827827
    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.

  • Patent number: 4640724
    Abstract: The invention provides a method of priming a blank or bulleted rimfire cartridge comprising the steps of (a) dosing into the rimfire case a quantity of a substantially dry, powdery, relatively insensitive premix comprising, in predetermined proportions, at least two materials that will, in the presence of a liquid reaction medium, react together forming a primary explosive compound, (b) compacting the premix so as substantially to fill the rim of the case therewith, (c) dosing a quantity of the liquid reaction medium into the case so as to cause said materials to react together forming the primary explosive compound and (d) drying the primer. By compacting the premix into the rim before the addition of the liquid reaction medium, the conventional spinning step may be dispensed with, thereby making the priming process safer and more economic.
