Abstract: 9445. Moreau, J. A. April 18, 1910, [Convention date]. Steering and balancing.-An aerial machine is maintained in longitudinal equilibrium by a swinging car, which may be locked by a frictional brake to the frame of the machine. Vertical steering may be effected from the car. As applied to a monoplane, the car c is pivoted about a transverse axis d, and is connected through links i, k<1>, to the tail g pivoted at f. The link k<1> is fixed to a shaft carrying a pulley l<1>, which may be rotated from a hand-wheel q<1> when the tail is to be manually operated for vertical steering. A modified form of connexion is shown in Fig. 5, in which the rods h, fixed to the tail have guides r' formed in them. Links t' pivoted to the axle d and links u<1> secured to a nut v' on a screwed shaft a<2> are pivoted to a bar s<1> sliding in the guides r'. The nut v' may be moved by rotating the handwheel g'. A further modification is shown in Fig. 6, in which the car is connected, by a crank g<2>, link f<2>, link d<2>, pivoted at e<2> to the fuselage, and rod h<2>, to the guides j<2>, and also, by links c<2>, b<2>, with the axis f of the tail. In all three forms, movement of the frame relatively to the car causes the tail to restore equilibrium. (See also paragraph below). Aerial machines without aerostats; planes, arrangement and construction of; controlling motive power, gear for.-The monoplane shown has planes comprising a central part b' and lateral parts b<2> so that they may be detached from the machine, a trapezoidal tail g, which may be in two or more parts for ready transport, a motor k and a propeller m. To start the motor, a magnetic or other clutch may be inserted between the propeller and the motor. (See also paragraph below). Cars.-The car c is suspended from a transverse axis d. In order to lock the car to the machine, a treadle k<2>, Fig. 7, is pivoted to the flooring and carries rollers o<2> which pass over and under a rope n<2> fixed to the frame so as to grip it frictionally when the treadle is depressed. (See also paragraph below). The Specification as open to inspection under Section 91 (3) (a) comprises also the following subject-matter which does not appear in the Specification as accepted:- Planes, arrangement and construction of. - The planes b<2> are constructed of a rigid front beam y and a flexible rear beam z<1>, the two beams being connected together by wires with elastic insertions and tensioning devices so that the curvature of the plane may be regulated. The angle of incidence of the planes diminishes towards the tips, which are flexible for warping. The planes are stayed above and below by wires with elastic insertions, except those staying the front beam y from below which are tensioned to prevent upward displacement of the beam. Cars; steering and balancing.-The car is suspended by a cardan joint so that transverse equilibrium may be maintained. A brake may be used to deaden the transverse oscillations. The planes may be warped separately at the two sides for horizontal steering or for balancing. Shock of landing, deadening; adapted to travel also on land.-The machine is supported on wheels o carried by a frame pivoted at q and cushioned by a spring r and a rear wheel u capable of turning about a vertical axis. Deformable skids s are also provided. Framework.-The uprights of the frame comprise two laths q<2>, Fig. 11, with compressed cork r<2> between, the whole being nailed or glued and covered with cloth. The uprights are connected to the longitudinal members by a slit and tongue joint. The longitudinal members comprise three laths s<2> with spaces t<2> filled with cork. Controlling motive power, gear for; motor appurtenances, arrangement of. -The enginecontrolling parts are operated by flexible transmissions passed through the axis of suspension of the car. A radiator n is placed at the front of the framing below the planes.
