Abstract:
1. Projectile containment system for trapping bullets therein, and comprising: A) at least two opposing generally flat hardened steel plates defining a convergent passageway for directing the bullets downstream into a throat area defined by the downstream ends of said two opposing plates, B) a containment chamber, defined by a plurality of hardened steel turning vanes arranged in side by side overlapping relationship to form a generally cylindrically shaped chamber having an inlet opening oriented at a substantial angle to the plane defined by said downstream ends of said hardened steel plates, C) a support frame having top and bottom support plates defining vane openings for loosely receiving end portions of said turning vanes, and vane biasing means acting on said turning vanes to urge at least the majority of said vanes radially inwardly of said containment chamber to impede and turn the bullets entering said chamber inlet opening, D) a transition passageway between said throat area and said containment chamber inlet opening, said transition passageway defined by opposing transition inlet plates forming an extension of said throat area, and at least one impact plate/vane provided downstream of one of said opposing inlet plates and oriented at an angle in the range of 10-15 degrees relative said opposing transition inlet plates, said impact plate has a downstream edge provided adjacent to a first turning vane defining a downstream edge of said chamber inlet opening.
