Abstract: 206,086. Revelli, B. A. March 22, 1923. Machine guns; cartridge magazines.-Cartridge magazines are in the form of a rectilinear box adapted to hold two piles of cartridges side by side and provided with means for compressing the feeding-spring to allow of easy insertion of a packet or clip of cartridges. The magazine shown in Figs. 1, 3 and 3<a> is hinged at the side of the breech-body 5 and is provided with a link 7 adapted to compress the feeding-spring 3 when the magazine is turned down. The magazine is charged by a clip of cartridges inserted through an opening in the back wall. The clip comprises a strip 12, Fig. 3a, of thin sheet metal or other flexible material folded so as to surround the cartridges from end to end and provided at the back with an extracting tab 13. After the clip has been inserted, the opening in the magazine is closed by a sliding cover 11 which passes be tween the bases of the cartridges and a back loop 12' on the clip. The clip is then removed by a pull on the tab 13. In the magazine shown in Fig. 5, the feeding-spring 3 is mounted in a side compartment and the feeder 4 is hinged to a slide 22, and when in its lower position can be moved aside to allow the cartridges to be charged into the magazine from the bottom. The cartridges are carried by a clip 25, Figs. 7 and 8, of flexible material, having turned back side edges 25<1> and a tab 26. After the packet has been inserted the feeder moves back to its operative position and the clip is removed downwards. The magazine shown in Figs. 9 and 10 is fitted above the breech body, and the cartridges are loaded through the mouth of the magazine, the breechbody being formed with a through aperture to permit the insertion of a charging frame, Fig. 13. The feeder can be raised, to compress the feeding spring, by a knob 113. Spring pawls 115 retain the cartridges. The pawls are formed with half-round pivots 119 acted on by spring plungers 116. The charging-frame has a handle 132 and two grooved bars 128, 129 to receive the ends of the cartridges.

Title: Improvements in aircraft control and brake devices
IPC: B64C25/44
Filed: 1929-03-14
Abstract: 330,634. Gloster Aircraft Co., Ltd., and Folland, H., P. March 14, 1929. Controlling. - A rudder bar which can be adjusted to suit pilots of different leg length is composed of two arms 1, 2, hinged d together about an axis coincident with the pivotal axis of the rudder bar, movement of the bar as a whole being transmitted to a lever to which the control cables are attached. Brake control pedals 18 are mounted on the rudder bar arms and actuate control wires or rods passing from the pedals along a line substantially co-axial with the pivotal axis of the rudder bar. Adjacent ends of the arms 1, 2 are forked at 3 to embrace one another and are freely mounted on a hollow spindle 4. The torque exerted by the pilot on the rudder bar arms is transmitted by links 7 to a saddle piece 9 adjustably mounted on a tube 12 secured to a member 13 keyed to the spindle 4, which is thus caused to rotate with the rudder bar. Adjustment of the angular setting of the arms 1, 2 is effected by screwing a nut 10, upon which the saddle piece 9 is mounted, inwardly or outwardly along the threaded sleeve 11 carried by the tube 12, either by means of a gear wheel, Fig. 1, adapted to be actuated by foot controls or by a hand wheel, Fig. 4. The pitch of the screw thread is such that the nut 10 is irreversible. The pedals 18 are carried at the outer ends of sleeves 17 which are rotatably mounted on the arms 1, 2. Lugs 19 at the inner ends of the sleeves are connected by links 20 to pivoted quadrants 21 which are grooved at their peripheries to receive brake actuating cables passing through the spindle 4.

Abstract: 1,218,436. Multiple cameras. PHOTO-ME INTERNATIONAL Ltd. Feb. 21, 1969 [Feb.21, 1968], No. 8387/68. Heading G2A. A photographic apparatus of the coin-operated type, in which a photograph of a person sitting in a booth can be taken by one of two cameras, is characterized by the mechanism for moving the camera unit so that the desired camera is brought into the operative position. The camera unit C comprises the two cameras 5 and 5a, having a common focal plane, camera 5a taking a single photograph on a sheet of sensitized paper, and camera 5 taking four smaller photographs on the same sized sheet. The diaphragms of the four lenses of camera 5 can be adjusted simultaneously Fig.4, (not shown). The camera unit can slide along a guide rod 31, which is disposed at right angles to the direction in which the sitter is photographed, a mirror 34 being placed in the light path to deflect it at right angles. The guide rod 31 is fixed on a base-plate 29. The camera unit is moved by an electric motor 35 mounted thereon, the motor driving a rotatable shaft 36. At the lower end of shaft 36 is fixed an arm 37 which carries a roller 38 at one end. Roller 38 runs in a track 39 extending along the base-plate 29 at right angles to the guide rod 31. Thus as rod 36 rotates, roller 38 runs along track 39 and hence the camera unit C is constrained to slide along the guide rod. Motor 35, and hence movement of the camera unit, is controlled from an electronic programming unit E, which controls all the camera movement, exposure, and processing operations. Also described are arrangements for feeding and metering the sensitized paper from a reel in a magazine 51, and severing a suitable length. Lamps are provided for suitably fogging the paper to produce a white border, for both the single and quadruple picture arrangements. After exposure, the paper sheets are fed into carriers 75, which immerse them in a succession of processing tanks.
