Integral Patents (Class 102/463)
  • Patent number: 9500453
    Abstract: A wad or basewad for ammunition includes an ignition chamber. The ignition chamber can be integrally formed with the payload wad, basewad, or battery cup or can be attached to the payload wad, basewad, or battery cup. The ignition chamber communicates with a primer of the ammunition to receive and contain the primer blast for at least an initial period of time. This facilitates faster initial ignition of the propellant of the ammunition, and consequently allows higher performance levels to be achieved. Other advantages regarding other applications of this invention include cleaner burning loads, greater economy, and lower perceived recoil.

  • Patent number: 7461597
    Abstract: A closure wad is placed at the mouth of the launching end of a shotgun cartridge before the mouth is crimped down to seal the launching end of the cartridge. Both the walls of the closure cap and the walls at the mouth of the plastic envelope are crimped down together, thereby forming a substantially impermeable seal at the launching end of the cartridge. In addition, the inventive closure cap substantially reduces the detritus which is sometimes expelled when a launcher cartridge is fired.

  • Patent number: 6988450
    Abstract: Anti-personnel tank fired ammunition designed for attacking personnel at various ranges includes a hollow base member adapted with an electric primer and a plastic or aluminum canister containing a payload at one end thereof. In operation, the hollow cartridge is loaded with a solid propellant. The electric primer which is centrally located in the solid propellant is fired and provides a flash together with the gasses needed to ignite the propellant. The burning propellant then provides the gasses needed to force the canister from the gun tube in which the ammunition is positioned.

  • Patent number: 5121693
    Abstract: An increased volume shotshell having a biaxially oriented plastic tubular body has an end closure disk heat sealed to the open end of the shotshell eliminating the conventional star crimp closure. The increases volume results from making available the space normally taken up by the internal folds of the crimp. The end closure on the open end of the shotshell tube is fused to the tubular body to seal the shot load without destroying the biaxial orientation of the open end of the tubular body.

  • Patent number: 4991512
    Abstract: A moisture seal is designed for a shotshell having a biaxially oriented plastic tubular body. The seal is a composite of a thermally conductive layer and a thermoplastic such as high density polyethylene laminated together. The rim portion of the inner layer of high density polyethylene is bonded or fused to the tubular body to seal the shot load end without destroying the biaxial orientation of the tubular body adjacent the rim portion. The moisture seal may be installed inside the tubular body and fused to the inside surface of the tubular wall or may be installed in place of or over the end closure and fused to the outside surface of the tubular body.
