  • Publication number: 20210310764
    Abstract: An extendable baton includes first and second telescoping tube sections, the first tube section having two inner circumferential grooves near one end. A cam assembly is carried by the second tube section for selectively locking the first and second tube sections to each other. The cam assembly includes two radially movable cams each having two lands and a groove therebetween. The two cams are movable radially relative to each other between a locked position in which the lands on the two cams are engaged in the grooves in the tube section, and an unlocked position in which the lands on the two cams are displaced radially inward from the grooves on the tube to enable relative axial movement of the first and second tube sections.

  • Patent number: 9644932
    Abstract: A stun grenade includes a fuze assembly secured to a housing adjacent gas outlet ports. The fuze assembly includes a fuze body having contact surfaces located in the flow path of the gas from the outlet ports so that gas flowing from the outlet ports impinges on the contact surfaces. The contact surfaces of the fuze body extend at an angle of no more than about 50 degrees to the first direction.

  • Patent number: 9618306
    Abstract: A munition includes a projectile and a propellant unit. A propellant insert in the propellant unit has at least two propellant chambers each receiving a respective propellant charge. A primer mechanism is actuatable to ignite all of the propellant charges in the propellant insert. The combustion products of a selected one of the propellant charges are directed to the projectile and the combustion products of the non-selected propellant charges are vented.

  • Patent number: 9500451
    Abstract: A munition includes a projectile and a propellant unit. The propellant unit includes a shell having a cylindrical configuration centered on a longitudinal central axis of the munition. The shell has a cylinder opening that receives a cylinder. The cylinder is selectively rotatable in the cylinder opening about a cylinder axis, offset from the munition axis, between a plurality of firing positions. The cylinder has a plurality of propellant chambers each with a respective propellant charge. The propellant chambers are located in the cylinder so that when the cylinder is in a firing position one of the propellant chambers is on munition axis.

  • Publication number: 20160209139
    Abstract: A projectile launcher has a drive mechanism for rotating a rotary magazine. The drive mechanism including a drive shaft fixed for rotation with the magazine about the axis. The drive shaft has a plurality of grooves. A detent member is in engagement with the drive shaft. Relative axial movement between the detent member and the drive shaft causes rotation of the drive shaft and thus the magazine, about the axis, without movement of the drive shaft an axial direction.
