Abstract
A battery operated propulsion unit secured to a SCUBA divers air tank consisting of three chambers; the center one containing the propeller drive motor. On each side of the motor is one battery chamber which contains the batteries that supply the power for the propeller drive motor. The propeller is surrounded by a propeller housing. Wired in series with the motor and power supply batteries is the motor control. Wired in parallel or in series depending on the position of the switch and in series with the motor control and motor is a speed control switch.
Claims1
An improved SCUBA divers propulsion unit strapped to an air tank that is in turn strapped to the SCUBA divers back rather than held in front of said diver;
- and designed to give said diver freedom of his hands for performing other functions;
- and to eliminate the necessity of setting said unit aside when use of the hands is required for other functions;
- the said unit comprising:
- a one piece unit housing consisting of:
- a tank mount of such shape as to conform to the curvature of said air tank;
- two power supply housings symmetrically opposite each other secured to either side of said tank mount;
- a propeller housing centered between and secured to said power supply housings and secured at the bottom to said tank mount;
- a motor housing centered between and secured to said power supply housings by means of two motor housing supports, one of each of said motor housing supports secured at one end to an opposite side of said motor housing with the other end of each said motor housing supports secured to the center of each of said power supply housings;
- a power supply made up of eight one and one half volt cells;
- four of each said cells mounted in each of the two said power supply housings;
- two power supply housing covers, one each of said power supply housing covers secured to the front of each of the said power supply housings by means of non corrosive screws to make a water tight seal to protect said power supply cells;
- a motor sealed within said motor housing, powered by said power supply;
- a propeller secured to and driven by said motor to provide the required thrust to propel said unit and said diver through the water;
- a double pole double throw switch mounted on said power supply housing cover and wired in series with said power supply and said motor having a purpose of supplying either 6 volts or 12 volts to said motor depending on the position of said switch;
- a motor control either held in the hand of said diver or clipped to said divers tank harness and wired in series with said motor, said power supply, and said double pole double throw switch to energize said motor when propulsion is desired by said diver;
- four straps, one each being attached to each of the four corners of said tank mount with the purpose of securing said propulsion unit to said air tank.
