Abstract: 28,526. Hanriot, R., and Pagny, H. H. Dec. 11, 1911, [Convention date]. Aerial machines without aerostats; planes, arrangement of.-In order to provide for the ready dismounting and assembling of the supporting-planes of an aeroplane, the front spars a, Fig. 2, of the planes fit in sockets in the fuselage and the rear spars bare hingedly connected to a plug b<4>, Fig. 7, movable in a rear socket b<2> in the fuselage. When the planes are to be dismounted for transport, they are moved outwards to detach the ends of the spars from the sockets. The plane can then either be turned through ninety degrees around the axis of the rear spar and afterwards folded along the fuselage by rotation around the pivot pin b<9>, or be first turned upward around the pivot pin b<9> and then moved alongside the fuselage by rotation around the axis of the socket b<2>. The upper shrouds c<5>, Fig. 16, are connected to the cabane in such a manner that they can be readily dismounted and refitted at the same adjustment. The struts c of the cabane are all secured at their upper end to a tube c', in which a second tube c<2> is adapted to slide. On the tube c<2> externally of the tube c<1> is screwed a socket c<3> carrying the yokes c' for the shrouds. The top of the tube c' is screwed and provided with a nut c<6> and cap c<7>. When the parts are in the position shown, the length of the shrouds is adjusted once for all and a hole is drilled through the tubes to receive the pin c'. When the wings are to be folded the pin c<10> is removed, the cap c<7> and nut c<6> are unscrewed, and the tube c<2> with the shrouds attached is withdrawn. In order not to weaken the longitudinal members of the fuselage, the struts c of the cabane have lugs c<8> fitting over the frame rods and clamped thereto by bolts. The empennage or tail of the machine comprises two planes D, Fig. 2, formed of tubular frames and is adapted to be adjusted in inclination and folded against the fuselage for transport. The planes D, Fig. 10, are connected at the front to the fuselage by a tube d rotatable in sockets d' and at the rear by a vertically adjustable tube d' integral with a socket d<4>, Fig. 12. The socket is secured by a pin d<5> to a tube d<6> slidable in a fixed tube d<8> provided with side slots for the passage of the pin d<5>. The tube d<6> is moved vertically by the screwed nut d<7> for adjusting the inclination of the tail. The tubes d<2> of the planes are connected to the fuselage intermediately of their ends by collars d<10>, Fig. 14, in which they can turn. The tubes are clamped in the collars by bolts d<11>. The collars are movable on guides d<12> to which they may be clamped by screws d<13>. The planes D are also connected to the fuselage by adjustable struts. The rear elevators E are pivoted on the rear tubes of the planes D, and are interconnected by a rod e pivoted at e' and passing through a tube e<2> integral with the socket d<4>. In order to fold the tail and elevators against the fuselage, the struts are removed and the bolts d<11> of the collars d<10> are unloosened. Steering and balancing.-The elevating planes E are simultaneously operated by cords e<4> connected to a controlling-lever, which is also movable laterally to control the warping of the main planes. The rear rudder F is controlled by a foot-lever. Shock of landing, deadening. - The machine is supported by two independent frames, each comprising two standards g bolted to the fuselage and fitting in sockets g<1>, Fig. 21. The sockets are connected to the landing-skids H by slings hand tolts h<2>. A hole h<3>, Fig. 18, is secured to each skid by lugs h<4> fastened by bolts.
