Abstract: 12,369. Waller, J. E., and Statter, J. G. May 25. Aerial machines without aerostats; propelling; steering and balancing by adjustment of propellers and aeroplanes, automatically and manually. The machine is provided with sustaining vibratory wings and screw propellers, which are geared respectively to the casing and shaft of a motor of the type in which both of these parts rotate. Either of the rotating parts can be braked so as to vary the proportion of power supplied to the wings and propellers. The wings are valved and are given a parallel motion the amplitude of which can be varied, while the parallel motion may be converted into a flapping motion of variable amplitude. The amplitude of the wing stroke on either side of the machine may be differentiated for balancing. Wings such as described may be applied to dirigible balloons. The wings 4 have dependent rods 26 and are connected by parallel links 27, 28 to the machine. The links 27 are oscillated by connecting- rods attached to the gear-wheels 31. Dash-pots 49 interposed in the links 28 and air-pumps 47 connected to the links 27 absorb shock. The amplitude of the parallel motion can be varied by connecting the gear-wheel with an intermediate slotted rocking bar 36, Fig. IV, to which the connecting-rod 38 of the link 27 is connected by a sliding block 39. In order to vary the nature as well as the extent of the wing stroke, the lower links 28 may be connected to a block 43, Fig. V, adapted to slide upon the fixed framework 44. Further, blocks 45 may be slidablv mounted upon the block 43 so as to be capable of separate adjustment. to differentiate the wing strokes for lateral balancing. The nature of the wing stroke for the positions 30, 30<Î>, 30<Î><Î> of the inner end of the link 28 is shown by the lines 4, 4<Î>, 4<Î>x. Differentiation of the wing stroke on either side for balancing may also be effected by pivoting the inner ends 30 of the link 28 to a disk which can be partly rotated. Automatic balancing may be effected by causing the sliding blocks 45, Fig. V, to be operated by a pendulum controlling the valves of compressed-air pistons connected to the blocks. Longitudinal balance may be controlled by sliding the rear aeroplanes 6 upon a framework 1. Planes, arrangement of. - The wings may be employed as stationary supporting-planes, and front and rear planes 5, 6 are also provided. The rear planes 6 are adjustable longitudinally of the machine. Anchoring.-The machine may be restrained at starting by an anchor rope 18 running round a peg 19 to a hook 21, from which it can be slipped by the hand-lever 22 which carries the hook. Starting is effected by a rope 12 fixed on to a fixed peg 17 and adapted to be wound upon a drum 10, which can be clutched to the motor. At starting, one element of the motor is braked so that the wings are stationary and the propeller 3 revolves. The brake is released as the rope is wound in. Or the wings may be operated and the propeller 3 be stationary at the start. The propeller blades may be adapted to feather, to avoid the necessity for the anchoring-device.
