US 2004/0069177 A1 · Non-lethal projectile ammunition

Abstract

Non-lethal ammunition for a riot gun includes a forwardly open casing, a projectile mountable in and dischargeable from the casing, a propellant cartridge extending into the casing interior, and a UV curable adhesive disposed in sealing relation about the propellant to effectuate uniform firing of the projectile. The projectile includes rearward and forward end portions each provided with a central cavity with the rearward cavity enclosing the cartridge, a weight in the forward cavity for balancing and increasing the mass of the projectile, and a subassembly carrying in a nose thereof a chemical payload or chemical agent, the subassembly including a stem sized for interference fitment within the forward cavity to secure the subassembly to the projectile and having a chamber for positioning the weight in the forward cavity.

Dependent claims

Non-lethal ammunition, comprising in combination, a cylindrical casing closed at the rearward end and open at the forward end, a propellant cartridge mounted to the rearward end and having a discharge end extending into the interior of said casing, a chemical sealant disposed about the propellant at the discharge end of the cartridge to facilitate uniformity of propellant firing, a projectile disposed in said casing, said projectile including a rearward end portion having a central cavity proximate to the rearward end of the casing and a forward end portion, the central cavity enclosing the cartridge and adapted to receive propelling gases released upon detonation of the propellant, and a payload connected to the forward end portion.

A non-lethal ammunition projectile, comprising:

a projectile body removably emplaceable within a shell casing, the body including a forward leg having a cylindrical forward end portion for mounting a payload, a rearward leg having a chamber for receiving a propellant, and a medial collar exteriorly configured for sealing engagement with the casing wall when the projectile is in the casing, the legs and collar being generally cylindrical and concentrically disposed along a central longitudinal axis,
a mass disposed within the forward end portion for balancing the projectile and inhibiting tumbling of the projectile in flight,
a payload subassembly removably emplaceable within the cylindrical forward end portion, the subassembly comprising a closure member of resilient foam material, a nose member, and a payload, the closure including a stem sized to frictionally engage the wall of the forward cylinder and having a chamber to receive the weight whereby to position the weight centrally of the axis, and a cylindrical cap sized to closed the forward end of the chamber, and said nose member being dome-like and connectible in an interference fit to the cap whereby to form a chamber within which the payload is received.
