Abstract: 483,018. Model aircraft. BACK, W. E. Oct. 9, 1936, Nos. 27417, 28835, and 33658. [Class 4] A toy aeroplane or glider includes a longitudinal spar or framework A<1>, a main plane F<1> and resilient means G which for normal flight conditions hold the plane against the spar, but which permit the plane to move against the resilient means on the occurrence of abnormal forces on the plane. As shown, the spar is formed of side-members A, A<1> connected together by distance pieces. A fin is secured to the after-end of the spar and a tail-plane is pivotally mounted on a screw. Two chocks E form a bearing for a lath F secured to the undersurface of the wing F<1> which may be reinforced by plywood or ribs. A rubber band G passes over pegs G<1>, G<2>, the leading edge of the wing and through a slot F<2>. Forward movement of the band is limited by pegs G<3>, G<4> and a flexible member B<4> carrying a member B<5>. A buffer H is secured in-the leading edge of the wing, the ends and centre of which are reinforced by adhesive-tape. A piece of wire J<1> secured to the wing by a piece of adhesive-tape engages a rubber band K passing over a pin K<1> and adapted to be lightly tensioned when the wing is in its normal position. The wing may engage the band K through a link providing lost motion. The tension of the rubber bands may be adjusted and the band G may be secured to the wing by detachable pins. The plane may be made from a hollowed piece of wood and the body may be covered by fabric. Two or more rubber bands may be employed. A buffer L, launching hook L<1> and balance weight L3 are provided and the toy may be launched in the manner described in Specification 439,826. According to the second Provisional Specification the wing spar may be of built-up hollow construction and the wings may taper, the wing tips being swept forward.

A large aperture, such as that of a ship's hold or an aircraft storage pit, is closed by an assembly of panels, of which some at least slide or roll away from the aperture on inclined ways so that they open by gravity when released, winches or the like being provided for the closing movement. In the arrangement shown in Fig. 2 the opening is closed by four panels 3 ... 6, the larger ones 3, 4 moving away from one another and the smaller ones 5, 6 moving away from the sides of the former. The panels are released in sequence for opening. Door-operating apparatus.-The panel 4, Fig. 3, is mounted on rollers 8 running on inclined tracks 7 extending into a housing for the panel in the open position; auxiliary ramps 10 provide for rapid initial lowering of the outer edge of the panel. A cable 22 attached to the outer edge of the panel is carried over a pulley to a hand-winch 23 whereby the panel can be drawn to the closed position. In a modified arrangement the small panels 5, 6 (Fig. 2) may be mounted on pivots so as to swing upwardly, counterweights being provided and the winch cables being attached to arms on the panels. Fastenings.-The panel 4 is held closed by hooks 17, Figs. 2 and 3, pivoted to it and engaging fixed stops 16; these hooks may be lifted, to allow the panel to open, by a lever 19 actuated by a hanging cord. When the panel starts to move, a part 9 (Fig. 3) thereon engages cranks 26 connected by rods to other cranks 30 which lift hooks 32 securing the panels 5, 6. These hooks are rigid with shafts carrying bars 321. Fig. 2, acting as keepers for weighted hooks 36 which hold the panel 3. The panels are thus released in sequence for opening, and have to be closed in the same sequence.

In the construction shown in Figs. 1, 3, and 4, the end of the wiper arm 18 is secured within a barrel 19 provided within a housing 15 connected to the driving spindle 12. The barrel is formed with a cam 24 adapted to engage a plate spring 26 so that the wiper may be held by the spring in either of two positions, in one of which, shown in full lines, it bears against the screen and in the other position, indicated by chain lines, it is withdrawn from contact with the screen. The wiper may be connected by a crossbar to a second wiper with a similar arrangement at the end of the wiper arm. In a modification shown in Fig. 5, the wiper arm 18 is connected to a barrel 30 provided with a roller 29 for engagement with the plate spring 26. The barrel is mounted on a pivot pin 31 fitting in slideways 32 in the cheeks of the housing 15, and held in position by clamping nuts. By adjustment of its position the pressure exerted by the spring 26 against the wiper arm may be varied.
