Title: Improvements in and relating to aircraft structures
IPC: B64C3/00
Filed: 1942-06-12
Abstract: 557,729. Securing planes to aircraft. BLACKBURN AIRCRAFT, Ltd. and HAND, P. G. E. June 12, 1942, No. 8040. [Class 4] The centre wing-section of an aircraft is attached to the aircraft frame or fuselage at a number of points and to facilitate assembly and interchangeability, provision is made at the attachment means for adjustment in at least two directions. As shown, the centre wing-section A is attached to the fuselage at four points. The attachment means at each point comprises a bracket 1 mounted between a pair of longitudinal girders 5, 6 of the aircraft frame and from which the wing-section is suspended by a pair of links 15, 16, pivoted to brackets 17, 18 on a girder 19 of the wing-section and to pivots 13, 14 on the bracket. The pivots screw into the brackets 1 to engage an extension 20 of the girder 19 which can thus be adjustably positioned in the fore and aft direction relatively to the bracket 1. Each bracket 1 is secured to the girders 5, 6 at one end by a pin 2 and at the other end by a pin 26 passed through the bracket at 3 and through the eyed end of a screwed rod 4 by which the bracket can be drawn up against a trunnion 10 that bears on a sleeve 7 screwed into a block 8 fixed between the girders 5, 6. The set of the bracket 1 about the pin 2 can thus be adjusted by the parts 7, 4 which are locked in the adjusted position by nuts 11, 12. Lateral movement of the wing-section which would otherwise occur due to the link connections, is prevented by blocks 21, 22 that engage the extensions on the side of the section, the blocks 21 being disposed between the girders 5, 6, or the links on that side may be replaced by blocks mounted on the shafts 13, 14 but incapable of rocking movement. In mounting the wing-section, the links and brackets 1 are first attached thereto, the rods 4 are extended downwardly to permit attachment of the brackets thereto by the pins 26, the rods are drawn up and the forward ends of the brackets are then secured to the girders by the pins 2.

Title: Pneumatic device for driving headed objects
IPC: B25C1/04
Filed: 1975-02-26
Abstract: 1496271 Nailing gun A J SMITH 26 Feb 1975 [13 March 1974] 8046/75 Heading B4C A pneumatic nailing machine has an axially movable ram 14 to drive in nails fed serially from a magazine 18 the nails being held in an inclined position with respect to the barrel and means for serially discharging the nails into the barrel. As shown, the ram 14 is mounted on a piston 84 slidable in a cylinder 87. The cylinder is surrounded by an axially slidable vale 100 which alternately feeds pressurized fluid above or below the piston 84. As shown in Fig. 9 the valve 100 is seated against seal 98 prior to a nail driving stroke. A safety device 160 on the barrel 16 is provided to prevent accidental actuation. When the barrel is placed in contact with the workpiece it causes opening of valve 74 in pipeline 150 which in conjunction with the opening of a trigger actuated poppet valve 148 allows air from a storage chamber 102 in the handle 10 to pass through a pipeline 172 to valve 120. This valve 120 in its normal position allows equalization of pressure in chambers 102 and 112 which, due to the different areas of surfaces 106, 105 on valve 100 keeps the valve in its upper position. However, on actuation of valve 120 cuts off this communication and vents chamber 112 to atmosphere and causes downward movement of valve 100. The chamber below piston 84 is vented to atmosphere by means of openings 132 and chevron valves or seals 140a, 140b on these openings ensure that whichever side of the piston 84 is pressurized that pressure cannot leak to atmosphere. Upon release of poppet valve 148 and safety device 160 valve 74 is closed, valve 120 returns to its normal position, valve 100 rises and the space below piston 84 is pressurized due to actuation of a flexible disc valve 185 (Fig. 6) whilst the space above is vented to atmosphere allowing it to rise to the start position. Nails arriving from magazine 18 arrive at a slight angle to the barrel 16 (Fig. 6) and a piston connected to a nail engaging shuttle 44 draws them into alignment with the barrel whilst a surface on the shuttle prevents entry of any further nails.

Title: Illuminating Projectiles.
IPC: F42B12/62
Filed: 1919-03-31
Abstract: 125,072. Ordnance Engineering Corporation, (Assignees of Bergman, A. G.). Feb. 17, 191'7, [Convention date]. Projectiles; projectile fuses.-Relates to illuminating projectiles provided with parachutes or like sustaining-devices, and consists in providing means for checking the speed of the illuminant after it has been discharged from its casing during the flight of the projectile, and before the sustaining-device comes into operation. The main object of the invention is to enable the illuminant to be discharged at any point in the trajectory, irrespective of the speed of the-projectile. The projectile shown in Fig. 1 comprises an inner casing C containing the illuminant 0 and a sustaining parachute P attached to it, and an outer casing B enclosing the casing C together with a smaller and stronger parachute L which acts as a speed-checking device. A time-fuse enclosed in a tube E, which can be punctured at an appropriate point for the purpose of setting the fuse, is provided in the base D of the outer casing, in addition to an expelling-charge J. A fuse T and a charge S for expelling the illuminant are provided in the base R of the inner casing. The container V of the illuminating-charge is preferably made of sheet zinc, wound with iron wire. A fibre disk W closes the container at the top, and a fibre disk X<1> and a perforated metal disk X are placed below the container. The casings C and B are closed by covers Y and Y<1> respectively. The parachute cords are wound round the parachute bodies, the retarding parachute L being connected by a chain (not shown) to the base R of the inner casing. The fuse E is ignited by the gun-gases when the projectile is discharged. When the charge J is fired, the inner casing is expelled and the retarding-parachute operates. At the same time, the fuse T is ignited and subsequently fires the charge S. This expels and ignites the illuminating- charge which is then sustained by the main parachute P. Fig. 4 shows a modification in which there is only one casing a around the illuminant container. This casing has a charge p in its nose, which is connected by quick-matches s to a fuse h. In operation, the base c is first blown out by a charge e when it is fired by a time-fuse f. Almost at the same time, both the fuse h and the quick-matches s are ignited, and the charge p is fired, blowing the illuminant-container k backwards. A cup o thereupon drops off, allowing the retarding-parachute n to operate. Subsequently, a charge j, ignited by the fuse h, blows off the base-plug g, and the illuminant container k with its sustaining-parachute l are released from a cup m, with the illuminating charge ignited. The retarding-parachute is, in this construction, assisted by the backward action of the charge p, and may in some cases be dispensed with. Tail-wings d are provided.
