摘要:
A life saving disc adapted to be thrown with considerable accuracy to a person in distress. The disc is provided with peripherally arranged flanges for retaining a length of line as well as floatation rendering the disc buoyant in water. In use, line is retained by the user at one end, such that when the disc is thrown to a person in distress, the line is dispensed from the disc. The person in distress grasping the disc, can then be pulled to safety.
