  • Explosives disrupter
    Patent number: 6644166
    Abstract: A portable explosives disrupter for de-arming improvised explosive devices includes a barrel for housing a projectile, a mechanism for firing the projectile from the barrel, a breech which may be adapted to house a variety of firing mechanisms, a light-weight, semi-rigid, three-dimensionally flexible, recoil-absorbing system for orienting the device in relation to a target and minimizing the effects of recoil on the accuracy of the device, and a means for accurately aiming the explosives disrupter at a target. Three different firing mechanisms are provided, the first employing a firing pin and shock tubing, the second employing a metal sphere and shock tubing, and the third employing a firing piston and a source of compressed air.
    Type: Grant
    Filed: October 4, 2002
    Date of Patent: November 11, 2003
    Assignee: Battelle Memorial Institute
    Inventors: Graham Herbert Alexander, Jeffrey Taylor Stroup, James Patrick LaBine, Bradley Gene DeRoos
  • Firing mechanism
    Publication number: 20030047062
    Abstract: A portable explosives disrupter for de-arming improvised explosive devices includes a barrel for housing a projectile, a mechanism for firing the projectile from the barrel, a breech which may be adapted to house a variety of firing mechanisms, a semi-rigid, flexible support system for orienting the device in relation to a target and minimizing the effects of recoil on the accuracy of the device, and a means for accurately aiming the explosives disrupter at a target. Three different firing mechanisms are provided, the first employing a firing pin and shock tubing, the second employing a metal sphere and shock tubing, and the third employing a firing piston and a source of compressed air.
