Abstract

2131. Dennis, A. W., and Dennis, W. C. Jan. 28. Propelling.-A flying-mchine is provided with one or more pairs of propellers of helical form, and of quick pitch, one propeller of each pair having a right-hand thread and the other a left - hand thread, and the two being driven in opposite directions. One arrangement is shown in Fig. 3, in which the helical propellers d, made of gold - beater's skin or o t h e r f a b r i c stretched on a high framework and carried on shafts c, are rotated in opposite directions through suitable gearing by a motor e. The machine is provided with steering-devices, and may have aeroplanes.
