Abstract
A line throwing device adapted to be launched from a riot gun or similar tubular launching device comprises an elongated projectile that fits in the tubular launching device, a fin assembly slidably mounted on the body of the projectile such that the fin assembly slides forwardly to permit the rear end of the projectile to be positioned in the launching device for launching and slides rearwardly to a flight stabilizing position at the rear of the projectile as the projectile is launched from the tubular launching device. A rocket engine is mounted in the rear of the projectile for propelling the projectile. An ignition mechanism comprising a conventional shotgun primer cap mounted in a plastic casing fits on the end of the rocket and is ignited by the trigger and firing pin of the gun. A line is coiled in a canister removably attached to the gun, with one end of the line being attached to a harness mounted on the projectile so that the line can be carried to the desired target.
