PNEUMATIC APPARATUS FOR SIMULTANEOUSLY RAISING A PLURALITY OF LOBSTER TRAPS FROM THE BOTTOM TO THE SURFACE OF A BODY OF WATER

摘要

A plurality of gravity submersible lobster traps secured in predetermined spaced relation along the length of an air hose. Each of the traps is provided with an inflatable float means connected to the hose and each float member having a pre-adjusted air escape valve therein. One end of the hose is connected to a source of compressed air in a boat and the opposite end of the hose is closed. When compressed air from the source is released into the hose, the floats on all traps will be inflated to a predetermined pressure dependent upon the adjustment of the valves, which will raise all traps to the surface for the convenient extraction of the catch.
