Abstract: 28,815. Keller, E. Dec. 21. No Patent granted (Sealing fee not paid). Steering and balancing.-(1) Automatically. The main spars 36, Fig. 3, of the wings of a flying - machine are mounted on vertical pivots 36<1> so as to be moved backwards and forwards by shafts 8, 9 which are rotated from a power-driven shaft 27 through clutches 10, 11 controlled by a pendulum 1. The clutches are actuated by arms 6, 7, Fig. 2, on a shaft 4 which is longitudinally displaceable by rods 5 mounted on the upward extension 1<1> of the pendulum rod 1. Each shaft 8, 9 comprises a central tubular portion 12, Fig. 6, connected to fixed outer pieces 15 by blade springs which serve to return the central portion 12 to its normal position when the clutch is inoperative. The wing arms 36 are provided with pulleys 35, 35<1> connected by cords to pulleys 32, 33 loose on a shaft 34. The pulleys 32, 33 are secured to pulleys 30, 31 connected by cords to pulleys 28, 29 on the shafts 8, 9 which are adapted to be rotated oppositely from the power shaft 27. (2) M a n u a l l y . In order that the wings may be controlled manually, pulleys 18, 19, secured to the shafts 8, 9, are connected by cords 43, 45 to pulleys 42, 44, Fig. 4. A hand-wheel 41 is secured to the pulley 42, which may be connected to the pulley 44 by a lever 46 so that the wings may be simultaneously moved. Duplicate operating-gear is provided comprising pulleys 18<1>, 19<1> on the shafts 8, 9 and pulleys 47, 48 which are provided with abutments 51, 52 adapted to be alternatively engaged by a pin 50 on the hand-wheel 49. 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. The steering-planes 73, 75, Figs. 8 and 9 (Cancelled), are carried by a jointed frame 54 pivoted at 55, 56 to the front of the machine and moved backwards and forwards by cords 57, 58 under the control of the operator. The planes can also be adjusted about a transverse horizontal axis and about vertical pivots. The planes are pivoted on vertical pivots 78, 79 to the frame 54, and are adjusted by cords 81, 82 passing around pulleys 80. The spars 72, 74 of the planes are provided with arms 70, 71 actuated by cords 66, 67. Springs 76, 77 are provided to return the spars to their normal position. The operating-cords 66, 67 pass around pulleys loose on the shaft 63, which are connected to the operating-mechanism. Planes, construction of.-The Specification as open to inspection under Section 91 (3)(a) comprises also the following further subject-matter. The wings are formed of a number of flaps 86, Figs. 10 and 11 (Cancelled), secured to ribs 87 pivoted at their inner ends 92 to the main spar 85. The flaps are normally held at right-angles to the spar by a cord 88, but when the wing is moved backwards for steering, as above described, they are drawn against the main spar 85 by springs 90. The flaps turn into a vertical position on the upstroke of the wing so as to offer no resistance to the movement. The socket 92, Fig. 12 (Cancelled), pivoted to the spar 85, is connected by a blade spring 96 with the inner part 93 of the wing rib 87 and a slot 101, Fig. 13 (Cancelled), permits relative movement between the parts. The sections 93, 97, 98 of the rib 87 are connected to one another by springs similar to the spring 96. The front and rear parts 99, Fig. 14 (Cancelled), of the flaps are inclined to one another in order to facilitate the collapsing of the flaps against the main shaft 85. In order to reduce the friction of the air, the planes and flaps and other exposed parts may be covered with plush connected by elastic tissue. This subject-matter does not appear in the Specification as accepted.
