Abstract: 275,720. Fowler, J. E. May 11, 1926. Aeroplanes; planes, arrangement and construction of; propelling; steering; land wheels and skids; sheck-absorbers, applications of. - The wings comprise upper, lower, and intermediate horizontal planes with diagonal planes extending between them, the lower planes being curved upwards at their outer ends, and improved control devices are provided for tilting the wings. On the body 16, Figs. 3 and 6, of the aeroplane are erected side walls. 23 to which are pivoted at 26 plates 25 which carry the wings. Each of the wings comprises an inner end plate 27 hinged at the rear to the plate 25 and secured at the front edge by fastenings such as intermeshing eyes 30 and a rod 31. The plates 27 carry three or more parallel and substantially horizontal planes 33, 34, 35 and extending between these and above the topmost plane 33 are diagonal planes 36, 41. All the planes are preferably cambered or made of a concavo-convex form with the undersides concave to receive the air forced against them by propellers 42 operating in slots in front running boards and driven by separate motors 43. The wing cells may be subdivided by other plane surfaces 47 diagonally arranged and also concave on their under sides. The lowest plane 35 is curved upwards at its outer end to meet the other planes and carries a skate or shoe 49 projecting beyond the wing structure and inclined upwardly to take upon the surface of water. The skates are hinged at the front edge of the planes 35 and provided with shock-absorbing bellows 51. The side walls 23 are connected by a plane 97 forming a space in which are arranged diagonal planes 98. A stud 67 on each plate 25 projects through a slot 68 in the wall 23 and is engaged by a slot in a lever 63 pivotally connected at its lower end to a link 58 for controlling the inclination of the wing. The front ends of the links 68 engage cranks 59, 60, Fig. 8, on trunnions 56 of a smaller V-shaped lever 21, the trunnions passing through apertures in the legs of a larger V-shaped lever 20 and engaging guided slides 57 which have a pin-and-slot connection with the links 58. The lever 20 is pivoted on a pin 54 extending through stationary beams 55 in the control cabin 17 of the body. Backward and forward movement of the lever 20 tilts both wings equally in the same direction, and similar movement of the lever 21 tilts the wings in opposite directions, the cranks 59, 60 being oppositely arranged for this purpose. A fixed toothed quadrant 114, Fig. 6, a movable toothed quadrant 116 on a slide 57, and movable pins 113, 115 on the levers 20, 21 are provided for locking the levers in any position. The rudder comprises a box-like structure 69, Figs. 9 and 12, with diagonal planes 73 and a base board 75 pivoted on a vertical pin 76 to a block 77 which is mounted on horizontal transverse trunnions 78 to provide universal movement to the rudder. A forward extension 81 of a pin 80 at the front of the rudder engages slots in vertical and horizontal slides 82, 83 which are moved horizontally and vertically respectively by cables 93 - - 96 guided by pulleys and wound around drums 91, 92, Fig. 8, which are controlled by hand-wheels 18, 19 in the control cabin. Ground wheels 100 are carried by pivoted arms 101 and pressed down by springs. 102; these wheels are adapted to fit within housings 104. Pilot wheels are also provided at the pointed ends of the body.
