135,835. Roe, A, V. March 22,1918, [Convention date]. Steering and balacing; planes, construction of.-A dual control gear for aircraft comprises joy-sticks 29, 30, Figs. 3 and 4, arranged to actuate the elevators by fore-and-aft movement about pivots 31, 32 by means of links 36, the two levers being connected by a curved rod 38. The pivots 31, 32 are carried by a rotary shaft 33 so that lateral movement of the joy-sticks operates the ailerons on the upper and lower planes by means of a sector 39 fixed on the shaft and connected to cables 40 passing over pulleys 41. The cables 40 lie in two separate grooves in the sector 39. The upper part 49 of the joy-stick 30 may be detachable. The two foot-operated rudder-bars 52. 53, Fig. 7, are conneeted to work in unison by cables 54, and are each pivoted to brackets 55 and mounted to work in horizontal guides 60. Foot-rests 63 with upstanding peripheries are provided for the operators. and stirrups 59 are provided at the ends of the rudder-bars. The rudder 9, Fig. 5, comprises an arcuate rim 11 connected to struts 12, 13, ribs 14, and bracing 15. The strut 13 is rotatably mounted in a tube 16 connected to the sternpost 17 of the fuselage, collars 18 on the tube 16 being attached to the rim frame 11. The tail-planes 5, Fig. 6, are composed of spars 22, ribs 23, and bracing 24, the members 22. 23 being connected by clips 25 to the contour frame members. The Specification as open to inspection under Sect. 91 (3) (a) describes also the following subject-matter, which does not appear in the Specification as accepted:- Steering and balancing.-The aileron cables 40 are connected together at opposite sides of the pulleys 41 by a cord 44. Planes, arrangement of.-The leading edges of the tail-planes 5 enter sockets 19, Fig. 5, on the fuselage, while the rear spars 20 are bolted to the stern-post 17.
