TODAY’S PATENT – UNDERWATER BREATING DEVICE
The UNDERWATER BREATING DEVICE was invented by Anthony M. Infante (Clearwater, FL) on 29th of March 1994, bearing the patent number US5297545A.
This invention relates generally to the field of draw-type snorkels and adds to pre-existing art an electrically powered diver-borne compressor that can be used to supply air to a free-swimming diver.
An electrically powered, diver-borne air compressor is used with a draw-type snorkel to supply air from above the surface to the swimmer. The use of non-positive displacement compressor that allows a shallowly submerged swimmer to breathe when the motor is turned off, which provides extended battery life. The compressor is selected to provide an adequate volume of air to a diver submerged at the depth limit set by length of the flexible air conduit leading from the surface to his/her mouthpiece. In the simplest embodiment of the invention, the excess air supplied to a less deeply submerged diver is vented through an exhaust valve. In other embodiments, this otherwise excess air is stored in a tank. When the tank becomes full the compressor is turned off until the stored air is exhausted.
