NEW LIFE PRESERVER HAS TWO PROPELLERS
Timid of sea travel because of his inability to swim, a Japanese lawyer of Los Angeles, Calif., has invented and patented a mobile life preserver. Hand cranks at the sides of the device turn a pair of diminutive propellers, enabling the wearer to advance at fair speed while remaining erect in the water. Thus a non-swimmer may reach a nearby shore without waiting to be picked up. The photograph above shows the inventor wearing his odd life preserver. Note the propellers and the hand crank that operates them.
