  • Patent number: 8783509
    Abstract: A method, device and system for metering powder material from a powder material source by a metering device connected to the source. The device is charged from the source with a batch of powder material in a charging configuration. The batch is discharged from the device in a discharging configuration. The source is connected with a metering piston space in the charging configuration via a first channel of a fixed metering channel hub. The volume of the space is controlled between a metering piston and a hub peripheral surface by controlling the piston position in the space, to charge the volume with material by gravity. The metering space is turned around the hub, to the charging configuration. The volume filled with material is enclosed until reaching the discharging configuration. The metering piston space is connected with a discharge opening via a second channel of the hub for discharging the material.

  • Patent number: 8683906
    Abstract: A ammunition loading machine is provided. The ammunition loading machine includes a base frame. A rake assembly is mounted to the base frame and configured to index a linear row of cases along a first linear axis. A platen assembly is also mounted to the base frame and is movable relative to the base frame along a second linear axis that is orthogonal to the first linear axis. A propellant hopper is fixedly mounted to the base frame. The platen assembly is movable relative to the propellant hopper to transfer propellant from the propellant hopper to a propellant filling mechanism that is movable with the platen assembly. The rake assembly is adjustable to accommodate multiple different sizes of cartridges. The rake assembly and platen assembly are commonly linked to a cam drive mechanism for simultaneously moving the rake assembly and the platen assembly.

The cartridge case having an interior space for receiving propellant charges and an open proximate end through which the propellant charges can be fed. An insulating sleeve defining an interior channel is affixed to the cartridge case and extends out of the proximate end of the cartridge case. The interior channel serves as a chute through which propellant charges can be fed. After the propellant charges are loaded, the insulating sleeve is crimped closed to retain the propellant charges within the cartridge case. A closure plug can be inserted into the proximate end of the cartridge case after the insulating sleeve is crimped closed.

  • Patent number: 8061274
    Abstract: A less than lethal projectile and method of producing the same comprising of a sealed filled polymeric pouch containing a shot within. The sealed filled polymeric pouch is formed in a form, fill, and seal machine. An automatic loading ammunition machine is fed empty shell casings; the ammunition machine automatically loads the empty shell casing with pre-determined quantities of wad, primer, and gun powder, and subsequently moves the sealed filled polymeric pouch into a projectile compartment of the empty shell casing producing a fully-loaded shell casing to be loaded into a barrel of an ammunition. The polymeric pouch is capable of being inserted into various shell casings depending on the intended use thus allowing for officers and soldiers to select from an array of munitions when confronted with a situation where less than lethal means are required.

  • Patent number: 4615255
    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).

  • Patent number: 4418606
    Abstract: A powder measuring device for use in connection with reloading cartridges has a powder transfer member supported for translating or, alternatively, rotating between a position where at least one cavity in the member is filled with powder from a hopper to another position wherein the powder is discharged through a tube to an empty cartridge. A cartridge to be reloaded is driven upwardly by a manually operated ram. The force for actuating the mechanism that drives the transport member is transmitted through the cartridge which means that unless a cartridge is positioned on the ram for receiving the powder the transport member will not be moved in response to operation of the ram and unintended discharge of powder will be prevented.

  • Patent number: 4295409
    Abstract: An attachment for dispensing shot and powder in conjunction with a shell reloading tool is disclosed. The invention is intended for use with those types of reloading machines which sequentially dispense shot and powder into a number of shells being progressively reloaded on the work table of the reloading machine. The device includes a frame mounted on the reloading machine and has a series of pivotable members which carry the shot and powder bottles. A sliding bar operatively connected to the actuating mechanism of the loading machine dispenses the shot and powder into the shells being reloaded at the appropriate time. The sliding bar includes a series of removable bushings which permit rapid change over to the dispensing of different amounts of powder and shot.

  • Patent number: 4292877
    Abstract: An ammunition loader has hoppers for shot and/or powder, and a slideable charge bar for metering shot and powder from the hoppers to the shell. Metering bushings are selectively disposed in the charge bar. A leakage opening in the side wall of the charge bar communicates with the outside of the assembly. The opening is blocked when a bushing is in place, but permits shot or powder to spill therethrough if no bushing is present. The bushings have exposed volume indicating indicia thereon.

  • Patent number: 4162645
    Abstract: A method of making a cartridge, in particular a blank or propellant gas cartridge which has a casing of generally tubular form with a telescopically reverse in-folded star-crimp-closed integral tubular end section, and within which is contained a blank propellant powder charge, with a readily rupturable wad of low heat conductivity initial restraining mass formed between the propellant powder charge and the in-folded telescoping star-crimp-closed end of the casing, in which method the cartridge is formed by front loading a propellant charge and the low-heat-conductivity wad, and then star-crimping and telescopically reverse in-rolling the cartridge casing, after which the recessed in-rolled star-crimped casing is heat sealed.

  • Patent number: 4148243
    Abstract: To uniformly load and orient predetermined charges of shot in shotshells having limited volume, an automatic loading machine meters the charges into the shells in a series of successive increments each sufficient to form only a single layer. A shell-supporting rail of the machine is subdivided into segments which are oscillated by cam and lever means to orient each successive increment of shot into a regular, compact layer.

  • Patent number: 4020737
    Abstract: A manual cartridge loading machine. The machine has six stations at which cartridges are operated on. Cooperable with the stations is a manually actuatable head carrying dies which execute the operations on the cartridge cases. The operations which are executed at the stations include: feeding the cartridge case; sizing the case and removing the old primer; belling the mouth of the case and seating the new primer; feeding the powder; feeding the bullet in the case; and taper crimping the case. Cartridges are shifted from station to station by a manually actuatable shifting plate which is constrained for quadrilateral movement, that is, in and out with respect to the stations, and right and left in a direction parallel thereto. A safety latch is provided so that the head cannot be manually pulled down unless the cartridges have been shifted by the shift plate.
