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.

A line throwing device adapted to be launched from a tubular launching device such as a riot gun comprising: a projectile including an elongated body shaped to fit in the tubular launching device and a fin assembly, including outwardly extending stabilizing fins, slidably mounted on the body for axial movement along the body, the fin assembly sliding forwardly to permit the rear end of the body to be positioned in the tubular launching device and sliding rearwardly to a flight stabilizing position as the projectile is launched from the tubular launching device, the projectile body comprising two interfitting tubes, an inner tube being mounted at a forward end of an outer tube and extending only a part of the way toward the rear end of the outer tube; rocket engine means mounted at the rear end of the projectile for propelling the projectile, the rocket engine and interfitting tubes being formed such that the rocket engine fits into the outer tube but not into the inner tube, the rearmost end of the inner tube serving as a stop to limit inward movement of the rocket engine into the body and to maintain the rocket engine at the rear of the projectile; ignition means mounted at the rear end of the rocket engine for igniting the rocket engine; and, a line having one end that is carried by the projectile from the launching device to the projectile target area for rescue purposes or the like.
