Abstract: 130,340. Roe, A. V. March 22, 1918, [Convention date]. Shock of landing, deadening; wheels and skids. -The front chassis comprises a central skid C, Fig. 1, supported by upwardly diverging rods 1, 2 pivoted to the fuselage and braced by wires 19. The wheel axle 6 is connected to the fuselage by upwardly converging rods 8, 7 having shockabsorbers interposed. The upper rod 7 is connected to a plate 11, Fig. 3, sliding on the lower rods 8, which carry a plate 13 sliding on the rod 7, the two plates 11, 13 being connected by elastic bands 17 which are surrounded by a fairing 16. The skid C is projected forwardly sufficiently to guard the tractor screw when landing, and is provided with a hook 5 at its rear end to serve as a ground brake. (See also paragraph below.) The Specification as open to inspection under Sect. 91 (3) (a) comprises also the following subject-matter, which does not appear in the Specification as accepted:- Wind-screens, arrangement of.-A glass windscreen 88, Fig. 28 (Cancelled,), is mounted in a frame 89 formed with pintles 90 engaging clamping-members 92 on a dash 91 secured to the fuselage. The clamps comprise split members 92 adapted to be tightened by wing-nuts 96 to hold the screen in various angular positions. Skids.-The rear skid N, Fig. 25 (Cancelled), is pivoted in a fork 81 at the lower end of a shaft 78 rotatably mounted in collars 77, 79. Fairings 85, 86 are fitted as shown, and the skid is provided with a shoe 87. Skids may be secured to the underside of the lower planes. (See also paragraph above.) Cars and cabins.-The front end or cowling of an aeroplane fuselage is constructed of four beams 7, Fig. 4a (Cancelled), connected at their front ends to a front plate 8 from which they extend radially and rearwardly, being interfitted at their rear ends with the longerons 5 and provided with braces 9. The seats 37, 38, Fig. 15 (Cancelled), are connected by hooks 39 to longitudinal beams 36 supported by transverse joists 34 connected to the side struts of the fuselage frame. Planes, construction of.-The main planes are provided with spars 19, 21, Fig. 7 (Cancelled), tapered at their outer ends. The ailerons F are strengthened by inclined spars 26 braced by a rod 27. The rudder K, Fig. 4c (Cancelled), comprises an arcuate rim 10, connected to struts 11, 12. The tail-pieces G<1>, Fig. 9 (Cancelled), are composed of intersecting battens 30 connected by clips 31. Fig. 10 (Cancelled), to the external frame member 29. The lower main plane is hollowed out at the centre of the rear edge to accommodate one of the pilots. Steering and balancing.-The rudder K, Fig. 4c (Cancelled), is attached to a post 13 rotatably mounted in a tube 14 connected by brackets 15 to the longerons 5. The elevators H', Fig. 9 (Cancelled), are hinged to the tail-planes at 32 by the means in Figs. 11 and 12 (Cancelled). A dual control comprises joy-sticks J, J<1>, Fig. 13 (Cancelled), arranged to actuate the elevators by fore-and-aft movement about pivots 49 bv means of links 44, the two levers being connected by a rod 45. The pivots 49 are carried by a rotary shaft 41 so that lateral movement of the joysticks operates the ailerons by means of a sector 46 fixed on the shaft, and connected by cables 47 to pulleys 48. The upper part 52 of the joystick J<1> may be detachable. The two foot.-operated rudder-bars 53, 54, Fig. 15 (Cancelled), are connected to work in unison by cables 55, and are each pivoted to brackets 56, Fig. 19 (Cancelled), and mounted to work in horizontal slots 61. Slotted guides 63 are provided for the operator's feet, and stirrups are fitted at the ends of the rudder bars.
