Multiple sets of blades in back & in rear.
In the operation of the invention it will be seen that the rotation of the driving-shaft B4 produces a simultaneous oscillation of the wings B and blades F and an oscillation in the opposite direction of the lower wings D and the rotation of the wings E, thus providing the simultaneous driving action for three separate devices reproducing, respectively, the propelling movement of a bird, a fish, and an insect, such as a bee.
