Abstract

176,909. Page, F. H., and Page, Ltd., H. Dec. 21, 1920. Steering, balancing, and regulating altitude; planes, construction of.-When flaps or ailerons hinged to the trailing portion of the wings are turned downwardly, slots between the wings and the flaps, or in the wings, or in the flaps, are uncovered, so that air can pass from the underside of the wing to the upper side of the flap without abrupt change in direction. When the flap 3, Fig. 1, is turned downwardly about its pivots 4, a slot is opened between the flap and the fairing 6 behind the main spar 2 of the wing. When the slot is formed in the wing, it is closed, when the flap is in its normal position or is moved upwardly, by a cover-plate, fixed to the flap and sliding over the slot, and is opened when the flap is moved downwardly. When the slot is in the flap, it may be normally closed by a cover-plate fixed to the wing and sliding over the upper surface of the flap; or the slot may be closed by a shutter 11, Fig. 7, pivoted at 12, and held in the closed position shown by a spring 17, but adapted to be opened, when the flap is turned down through the engagement of the arm 13 with a slot in a rod 15 anchored at 16 to the wing. Reference has been directed by the Comptroller to Specification 167,318.
