Abstract: 943,915. Aircraft framework. WHITWORTH GLOSTER AIRCRAFT Ltd. Dec. 16, 1959 [Dec. 22, 1958], No. 41311/58. Heading B7W. In an aircraft having a curved wall a curved frame member is provided to support a curved door attached to the frame by a plurality of a peripherally-located frusto-conical connections, which if the door is withdrawn in its curved state from the frame member will not readily separate. This is overcome by making the door sufficiently flexible to enable the connections to disengage and re-engage sequentially. The structure 1 is provided with a frame 6 having frusto-conical recessed sockets 5 each threaded at 8 to receive an attachment screw 7 loosely secured within a frusto-conical projection 4 attached to the peripheral edge of the door 3. To attach and remove the door, which has sufficient rigidity to normally conform to the curvature of the wall frame, the door is attached adjacent each extremity to a lever 10 as by a screwed attachment 11, each lever having a projection 12 which when a pin 13 is inserted in holes in the levers causes the door to be held in the flexed condition shown in Fig. 5. The central attachment screws are then attached to their respective sockets and the levers 10 released by removal of pin 13, whereafter the remaining projections may be inserted in and locked to their respective recesses. The door may be a skin panel of uniform thickness or it may be stiffened by longitudinal members or it may be double skinned; providing the inner skin is attached to longitudinal stringers at widely spaced intervals to ensure sufficient flexibility of the door.

Abstract: 1,189,926. Web roll supports. CUTTERS MACHINE CO. Inc. 5 Sept., 1968 [20 Nov., 1967], No. 42177/68. Heading B8R. An apparatus for supporting a roll of web material includes a frame having supporting standards for a primary roll and a carrier supporting an auxiliary roll, the carrier being so dimensioned as to facilitate transfer of the auxiliary roll to the standards when the primary roll is exhausted and discarded. As shown, a cloth spreading machine 10 comprises a frame 11 which is movable longitudinally over a cloth spreading table 14 and which supports a pair of upright standards 17, 18 furnished with respective bearings 19, 20, carrying the spindle 22 of the cloth roll 23, when in the spreading position. A carrier 30 is mounted on the rear of the frame 11 and is arcuate in cross-section so that it may support an auxiliary roll of material, the carrier being shorter in length than the distance between the standards 17, 18. Thus, when it is necessary to replace the primary roll the auxiliary roll can be elevated into the standards by depressing the near end of its spindle, using the edge 35 of the carrier 30 as a fulcrum, so that the remote end can be swung upwards into the bearing 20, the near end then being lifted into the bearing 19. The auxiliary roll can thus be positioned into the cloth spreading position without the operator having to take the full weight of the roll. The standards 17, 18 may be mounted on a carriage frame 25, movable transversely on the frame 11, to permit lateral adjustment of the roll 23 and the web 26 spread by the machine 10.
