Loading And Shell Closing Patents (Class 86/25)
  • Patent number: 9970741
    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.

  • Patent number: 8627770
    Abstract: A cartridge assembly for large bore gun systems having an integrated retention assembly for maintaining propellant charges within the cartridge case. 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.

    Abstract: An apparatus for resizing the neck of a cartridge case which includes a housing secured to a stationary head of a reloading press. A support sleeve is attached within the housing such that the support sleeve can slide within a bore of the housing. The apparatus utilizes interchangeable bushings, located within the support sleeve, which each have substantially the same outside diameter but which have varying inside diameters. The bushings are marked with their inside diameter and the user selects a bushing with an inside diameter which the user determines will most accurately resize the neck. To change bushings, the top portion of the housing is separated from the bottom portion of the housing and the components inside the housing can then be slid out of the end of the bottom portion of the housing. A different bushing can be substituted for the one that was previously used.

  • Patent number: 5313869
    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.

  • Patent number: 5179243
    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.

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.

The turret carries a plurality of cartridges for reloading, the cartridges being symmetrically spaced around the turret axis and adapted to be indexed around the axis in a step-by-step sequence. An overhead die holder contains a plurality of dies spaced in a symmetrical pattern similar to that of the cartridges but in fixed positions. A center opening in the die holder houses a rotatable bushing. The rotation of the bushing is controlled in part by a one-way clutch. An indexing shaft affixed to the turret extends from the turret axis through the bushing. The shaft has a multi-sided cross section and is slidably fitted to the bushing in a manner that prevents relative rotation. The configured cross section has an axial twist and when forced through the bushing by the reciprocating plunger, causes turning of one or the other of the shaft and turret or the bushing.

    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.

  • Patent number: 4512235
    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.
