ABSTRACT:
Apparatus to automatically inflate a life raft secured to the side of a boat hull by releasing a pressurized gas from a cylinder when the boat capsizes. The gas release mechanism for the cylinder includes a spring urged valve and a spring loaded plunger arranged to open said valve upon release. The plunger is held in an extended position by a lever arm pivotal about a pin and held by an extending arm connected to weights such that when the boat is overturned the weights pivot away from the lever arm due to the force of gravity, releasing the plunger, thereby releasing gas from the cylinder to inflate the life raft.
