Projectile backstop assembly
First Claim
1. A projectile backstop assembly for decelerating incident of projectiles comprising a boiler-like container,a liquid filing said container and serving as a decelerating medium for projectiles,said container having inner walls with rounded surfaces and having an inlet opening,an elongated sheet of material having a region adapted to be pierced by a projectile and sealingly closing said inlet opening,a pressure frame adapted to be pressed onto said region of material,pressure applying means to press said pressure frame against the pierced region of said material,means for advancing said elongated sheet along its longitudinal direction after disengaging said pressure frame whereby the pierced region can be replaced by an adjacent region of said elongated sheet.
