Abstract

PURPOSE: To increase propelling force and facilitate its manufacture by fixing two pieces of two-blade screws forward and backward along the shaft.
CONSTITUTION: A stream-lined hub 2 is screwed at the point part of a shaft 1 in order to prevent water flow which is accelerated backward from turbulence. Two pieces of pins 3 are fixed staggering 90° of the phase to each other on the shaft 1. Bosses 4 are tucked to the shaft 1, slitting type of engaging concave grooves 4a are engraved, which are tucked with pins 3 and fixed. Respective two pieces of blades 5 are incorporatively fixed onto the bosses 4, the front and rear blades 5 are arranged staggering 90° of the phase angle to each other, the twisting curvature of the front and rear blades 5 is in the continuous condition. Since as mentioned above, two pieces of two-blade screws are fixed forward and backward along the shaft, the water capacity to be pushed backward is doubled, and that much stronger propelling force can be produced.
