IPC: B64C13/12
Filed: 1918-04-16
Abstract: 131,071. Verner, J. F. April 16, 1918. Steering and balancing. - A dual control for aeroplanes comprises two levers 4, 5 having ball-andsocket connexions with levers 4<x>, 5<x> capable of lateral and d longitudinal movement to control the ailerons and elevator, each ball - and - socket connexion being normally held rigid by a spring-bolt sliding within each part 4<x>, 5<x>, but adapted to be withdrawn respectively by levers 24 carried by the parts 5<x>. 4<x>, so as to render either of the levers 4, 5 inoperative. Movement of the levers 23, 24 also affects the rudder-bar connexions. Two rudder-bars 38, 39 are provided which are normally connected by bolts 47, 88 to two shorter bars 42, 42<x> of which the bar 42<x> has connexions 40, 41 leading to the rudder, and the bar 42 has connexions 43, 44 connecting it to the bar 39. Cords 61, 62 lead from the bar 38 to devices 65, 66 which are normally connected to the rudder through cords 71<x>, 72<x>. Fig. 5 shows one of these devices 66 which has a stem capable of sliding in a fork 71 against the action of a spring 69. Normally the device is held rigid by two jaws 73 having tail-pieces connected to a cord 79 leading to the lever 24. Movement of the lever 24 to render the lever 5 inoperative also opens the jaws 73 of both devices to permit relative movement between the parts 66, 65 and their forks 71. Movement of the lever 23 to render the lever 4 inoperative withdraws the two bolts 47, 88 so that the rudder can only be operated by the bar 38. The parts 4<x>, 5<x> are connected by a rod 31 so that both may operate an elevator connexion 35, and both are mounted on a shaft 8 having an arm 36<x> connected to the ailerons. The levers 23, 24 have locking-quadrants 20, 21. Fig. 2 shows a section of one of the ball joints with the sliding bolt in its locking position.
