  • 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

  • Patent number: 6578464
    Abstract: A recoil mitigation device is provided for a projectile-firing device, such as an explosives disrupter, in which a brake is attached to a barrel of the projectile-firing device and the projectile-firing device/brake combination is positioned coaxially within a tube, the tube secured to a frame or other suitable foundation. The brake includes two or more brake shoes positioned within an annular free space defined by the outer surface of the barrel and the inner surface of the tube and adapted to frictionally contact the inner surface of the tube. An apparatus is attached to the barrel for limiting the lateral movement of the brake shoes and there is an apparatus for urging the brake shoes in an outward radial direction against the inner surface of the tube, whereby when a projectile is fired from the barrel, the brake mitigates the recoil of the projectile-firing device.
