Title: Improvements in or relating to aeroplane fuselages
IPC: B64C1/14
Filed: 1923-09-15
Abstract: 221,088. Fairey Aviation Co., Ltd., and Fairey, C. R. Sept. 15, 1923. Fuselages.-For enabling an opening in an aeroplane fuselage to be closed at will to any desired extent, movable panels are fitted to slide in guides from opposite sides of the machine, the panels forming virtual continuations of the outer streamline surface of the fuselage. The Figure shows a cross-section through one side of a fuselage at the pilot's cockpit in which a flanged flexible metal panel 11 has lateral pins 19 sliding in grooves formed between the outer flange of an angle-member 15 and a lighter angle-strip 17 secured thereto. A bent portion 22 of the strip 17 forms a retaining stop when the panel is in its uppermost position, another spring strip 23 serving a similar purpose when the panel is partially raised. For completely closing an opening, two pairs of panels are used, one sliding over another in each pair. In this case the pins at the edges are guided in slots in the members 15 and the opposed edges of the upper panels meet when closed in the central plane of the fuselage. Downwardly directed notches may be formed in the slots to retain the lateral pins when the panels are in their raised position. The upper opposed edges of the panels may have wired edges, the ends of the wires serving in place of the upper-pins 19. The back edge of the opening to the pilot's cockpit may be straight in plan and the uncovered part of the front edge may be forwardly arched.

Title: Improvements in or relating to parachutes
IPC: B64D17/52
Filed: 1920-08-09
Abstract: 175,308. Democratis, S. J., and Democratis, B. J., (Democratis J.). Aug. 9, 1920. Parachutes.-Relates to parachutes which are packed according to the system described in Specification 172,670 and are released from their containers on aircraft in a packed condition. Packing is performed by first folding the parachute material A, as shown for example at Fig. 1 (i). and then rolling it towards and around a structure B at the centre of the parachute, Figs. 1 (2) and 1 (3). When the pull of the load comes upon the rigging tapes L, after the parachute has been launched, the packed fabric moves away from the structure B and at the same time the peripheral portion of the fabric unpacks on the outer circumference of the pack. Several methods of folding the material before rolling it are described, one such method being indicated in Fig. 6 (1). The upper layer of folded fabric may be first rolled outwardly towards the circumference and the whole re-rolled towards the centre. There may be two or more circumferential rolls, Fig. 10 (3), upon which the pull of the load is exerted successively. To facilitate the opening of the parachute, the central aperture may be covered by a cloth H, Fig. 13, which is folded or rolled up with the parachute fabric A. The cloth may be loose and may carry the central structure B; or it may be attached to the main parachute so as to act as a pilot parachute. The rigging L may be packed in loops R, Fig. 20, which are secured on the parachute fabric A and may be connected by a tape S.

Filed: 1925-09-19
Abstract: 261,506. Brown, S. G. Sept. 19, 1925. Loud-speakers ; magnetic instruments.-In a toud-speaher of the kind in which a vibrating reed is attached to a diaphragm, means are provided for adjusting the position of the reed so as to regulate the air-gap in the magnetic circuit. In the form shown in Figs. 1 and 2, the reed 10 is carried by a T-piece 7 which is screwed at 9 to the arms of the V-shaped magnet 1. The reed lies in the upper part of the space between the laminated pole-pieces 4, and the gap between it and them is regulated by tilting the T-piece 7 by adjusting the set-screw 12, which passes through a hole in the tail 8 of the T-piece. The deformable arms of the T-piece serve as a pivot for the movement. An adjustable reed-stop 17 is carried by a plate 16 on the under side of the magnet. In a modification the pole-pieces are solid and have screwed to their under sides three brass plates 19, 20, 21, Fig. 4, of which the middle plate is shorter than the outer two. The latter carry a reed stop screw 23, and owing to their resilience they serve as a looking means to secure it during vibration. When the instrument is first assembled the pin 25 on the diaphragm may pass freely through a slot at the end of the reed 10, but after the magnets have been fixed in position the pin is soldered to the reed ; strains are avoided by this procedure which is particularly applicable to instruments of the type described in Specification 257,747.
