Abstract

221. Pelterie, R. Esnault-. Jan. 19, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Aerial machines without aerostats; aeroplanes; framework; propelling.-In an aerial machine provided with a pair of extending planes, the planes are flexible and are connected to a bar h, Fig. 1, supported below the machine, which is operated to cause the front edge of one plane and the rear edge of the other to be lowered simultaneously. The body of the machine comprises a trapezoidal frame a, b, Fig. 2, surrounded at intervals by hoops, which support a canvas cover. The planes e have flexible front and rear ribs, and the fabric is supported on stays pinned to the ribs so as to be able to bend. The tips of the ribs are connected by rodsf, g to the ends of a bar h supported on rods j. The bar h is secured to a rod i connected by bell-crank levers and links to an operating-lever 1, so that, by inclining the lever to the left or right, the planes are twisted in opposite directions. A rear rudder comprises two horizontal vanes r and two vertical vanes o secured on a ring p supported on a ball- and-socket joint. A rod 6 is connected to the lever 1 and to the ring p at its lowest point 7, and, when a forward or backward motion is given to the lever, the vanes r are turned about an horizontal axis. A second lever 8, connected by a rod 9 to the side 10 of the ring p, turns the vanes o about a vertical axis. A screw propeller is placed either at the front or rear of the machine.
