Abstract: 210. Huth, F. Jan. 5, 1909, [Convention date]. Aerial machines without aerostats adapted to travel also on land; planes, arrangement and construction of; propelling; steering.- An aerial machine is provided with annular supporting-planes constructed of overlapping frames of various shapes. Fig. 2 shows a triplane machine in plan and elevation, the fabric of the planes being stretched between the frames a, b. The upper plane may be over the others, or staggered as shown. The propellers are placed in the central space, and may be driven by separate motors, the propellers being connected together. The central propeller may serve as the fly-wheel of the motor. The motor may be connected to the ground wheels. Flapping wings may be used with the machine. The portions vr, vl hr, hl of the bearing-planes are movable for steering and maintaining stability. The parts may be connected to the correspondingly-marked parts shown in Fig. 4 On lifting the hand-wheel H, the bevel wheels are equally turned, and the front and rear planes are equally and oppositely turned, causing a change of altitude of the machine. Rotation of the wheel H causes the planes to be raised at one side and lowered at the other side of the machine, and also causes rotation of the vertical rudder, or of specially - provided planes, through ropes sl, sr, thus counteracting the increased resistance on one side of the machine. By this means, lateral stability is recovered. Lateral steering is effected by turning the whole steering- gear about the pillar g. Another form of steering-gear is shown in Fig. 5. By raising or lowering the shaft, the plane is symmetrically adjusted, and, by rotating the wheel H, the plane is warped, and the vertical rudder is moved through wires sl, sr. By moving the shaft in a slot f, the vertical rudder is operated without appreciably affecting the main planes. The steering-members are automatically maintained in position for straight flight, or the normal position is indicated. The relative inclination of the propeller axes and the planes may be varied to suit the speed of travel of the machine. The Specification in the original form, as open to inspection under Section 91 (3) (a), comprises also the following subject-matter: Intermeshing propellers, as shown in Fig. 4<a> (Cancelled), rotate oppositely in a casing indicated by the dotted !ines, whereby the lifting effect is increased. This is also effected by moving the propeller blades farther from their centre of rotation during the downward movement, as shown in Fig. 5<a> (Cancelled). The rod to which the blades f, f<1> are fixed slides transversely under the influence of the crank l, pivoted at m and engaging the rod at k. If the displacement takes place at one side only, the machine turns. The propellers may further be driven through eccentrics in order to accelerate the downward movement. Where several motors are used, the propellers are connected together, suitable clutches or free-wheel gears being provided. This subject-matter does not appear in the Specification as accepted,
