Oscillating wings operated by cranks, with slats which close during downward movement and open on the upward stroke.

Etymological nuances of 'orthopter' notwithstanding, "This invention relates to orthopters and has been devised to mechanically reproduce the actions of a bird during flight and under varying conditions of the wind and also to simulate the movements of a bird in rising from and descending toward and alighting upon the surface of the earth."

Inventor location: Cohoes, New York
