Abstract

28,195. Verity, C. H. A. Dec. 2. [Cognate Application, 10,902/10.] Aerial machines without aerostats; planes, arrangement of. -A flying-machine comprises upper and lower fixed planes or series of planes A, B connected together by framework E so that the upper planes A form an inverted dihedral and the lower planes B form a dihedral angle, as shown in Fig. 4. When series of planes are used, they are spaced apart and arranged in steps as shown in Fig. 1, and the angle of incidence or the area of the planes may increase towards the rear to give increased lifting effect. Moreover, each upper plane may be of greater area than the one below it; for example, each upper plane may extend at each side of the machine a distance of two feet beyond the lower plane. The machine is moreover provided with duplicated motors and propellers N, N' and F, F', elevators C operated by duplicate controls M, and rudders S<2> operated by duplicate pedals P<1>. Vertical fins may be fixed at or near the ends of each plane. Propelling.-The machine is provided with two propellers F, F' arranged as shown and driven independently by separate motors N, N'. The propellers are mounted loosely on their motor shafts but may be clutched thereto, the arrangement being such that, when only one motor is being used, the other propeller is unclutched and is rotated by the head-wind, so that when clutched to its motor shaft, its momentum serves to start the motor. Steering and balancing; stopping way.-The machine is steered vertically and balanced by elevators C hinged at each side of the machine to the rear of the top front planes A, and controlled independently by wires D connected to controlling-gear M placed at each side of the aviator. Two pairs of control gear M are provided for use by two drivers, and are connected together so as to facilitate teaching. Each control wheel M is fixed to a drum D', Fig. 3, to which the cables D are connected, and is operated by a lever T mounted loosely on the shaft S<1>. The lever T is clutched to the wheel M by pressing a spring push T<2>, and is simultaneously unclutched from a fixed boss C<1> by the withdrawal of spring bolts T<1> operated by wires W<1>. The machine is further provided with two rear rudders S<2> operated by pedals P<1>, which are also duplicated. The elevators and rudders may be moved at right-angles to the line of flight for braking the machine after landing. Shock of landing, deadening.-The machine is provided with land-wheels W mounted on long flexible shafts H, which bend upwards so that skids P come into contact with the ground when the shock of landing is severe.
