Title: Improvements in or relating to methods of or apparatus for performing trimming operations on toe-end portions of shoe uppers
IPC: A43D49/00
Filed: 1939-01-21
Abstract: 524,084. Lasting shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Jan. 21, 1939, No. 2119. [Class 17 (i)] Relates to machines for trimming lining materials at the toe end after pulling-over but before end-lasting so that the upper may be cemented direct to the insole, and consists in a machine having heating means for softening a thermoplastic stiffener and a knife which makes a series of draw cuts that progress simultaneously along both sides of the toe from a common starting point at the toe end. The shoe is supported by a toe support 23 urged upwardly by a spring 25 housed in a jack post 22 urged downwardly by a spring 30. The vertical position of the shoe is determined by a member 19 engaging the insole and carried by a slide actuated by a bell-crank lever 47 on the rising of the jack to clamp the lining and stiffener at their marginal parts at the toe end against a plate 20 also slidable to allow work insertion and to clamp, respectively. A pair of blocks 68 are heated by electric resistances 69 and are slotted to house a number of metal members 71 recessed to receive the margin of the leather upper when this is bent forwardly. The members are urged toward the shoe by a,cable 76 tensioned by springs 77. The margin of the upper is protected from excessive heat by an asbestos sheet 94 backed by a metal sheet 95. The two blocks 68 are adjustable about their meeting point at the end of the toe by a right-and-left-hand screw rotated by a hand-wheel 93, to fit shoes of differing shapes. The members 71 support the forward end of the member 20, and the whole heating assembly is carried by a member 52 'secured to the jack and raised with this by a treadle 21. A roll 35 carried by the jack co-operates with a surface 38 on a member 34 pivoted at 37 and linked to an arm on the treadle. A surface 39 on the member 34 maintains the jack in its uppermost position while the treadle is further depressed to allow a latch 40 to engage the pivot 37 and thus hold the treadle down. The knife is carried by a pair of arms 101 of a frame reciprocated along a rock shaft 102 by an electric motor. A narrow flexible blade is secured to the arms, and the rock-shaft is urged anti-clockwise by a spring, so that as the frame reciprocates the blade, by a series of draw cuts, severs the portion of the lining and toe-stiffener including any doubler, above the upper face of the member 19. The stiffener having been softened by heat is in a condition for lasting, which may be done at once in a machine of the kind described in Specification 475,127.

Abstract: 579,858. Automatic guns. DEARSLEY, G., and MOLINS MACHINE CO., Ltd. Feb. 7, 1944, No. 2266. [Class 92 (ii)] Relates to cartridge belt feed mechanism for fixed barrel guns of the kind in which the belt is fed by a loaded spring which is rewound by a ratchet mechanism operated by a recoiling part of the gun. The invention consists in providing a cam surface 15, Fig. 1, fast with a recoiling part 14 and having a rise and fall of the same contour for actuating a follower 16 to impart a rewinding step to the spring on each forward and rearward stroke of the cam. The invention is shown applied to the belt' feed of a gun of the Oerlikon type in which a loaded belt enters a casing 2 by a passage 4 and passes over a spring-driven sprocket within the casing, the empty belt links leaving the casing by a passage 5, Fig. 3. The follower 16 engages the usual rack member 10 for rewinding the spring which drives the belt feed sprocket. Firing is stopped just before the supply of cartridges is exhausted by a member 31, Fig. 3, actuated through the linkage shown by a spring-urged feeler 22 which presses on the cartridges in the belt.

A continuous slab reheating furnace comprises a number of firing zones spaced along the furnace, disposed above and below a hearth 9 which has side walls 10, 11, spaced inwardly from the side ,walls 2, 3 of the furnace and extending above the level at which the slabs 18 are supported on skid rails 17 carried by pillars 16. Combustion gases from the space 22 above the hearth are obliged by walls 10, 11 to pass upwardly away from the slabs 18 on their way to the discharge openings 6, 7, whilst gases from below the hearth flow downwardly away from the slabs through openings 14 and tunnels 15. Gas flow around the slab edges 19, from below the hearth 9 to above it, due to gas buoyancy is prevented by the extended lips 21 of walls 10, 11 which form a restriction 23 creating a higher pressure in space 22 than would otherwise exist to counterbalance the buoyancy effect. Smaller lips 20 may also extend inwardly from the bottom of the walls 10, 11.

Sheet-registering devices; carriers; dropping- roller and like sheet-feeds. - Printing or like machines fitted with a sheet-feeding mechanism comprising means for positioning the sheets correctly and forwarding them to grippers of the machine are constructed with a single device for collectively adjusting the timing of the operations of the positioning and forwarding means with relation to the press. As applied to a press in which sheets are fed over a table on a support 7 to grippers 8 on an impression cylinder 9, the sheets are advanced by a dropping-roller 74 carried by a curved arm 75 to a front stop 43 and are registered sideways by a pusher register 51. The sheets are finally forwarded by rollers 59, 61. The registering-devices and the dropping roller are all actuated by cams on a shaft 19 driven by chain-gearing from a sprocket 16 on a shaft 13, and the roller 61 is driven by a segmental gear oscillated by a crank-pin on a gear-wheel driven from the shaft 13. To enable all the devices to be adjusted with relation to the press, the shaft 13 is driven from the impression cylinder by a gear wheel 11 in gear with a wheel 12 which can be adjusted relatively to the shaft 13. The wheel 12 is normally secured to a disc 14 keyed to the shaft 13 by means of set-screws 21, Fig. 2, which pass through segmental slots in the disc 14. To adjust the wheel 12 these screws are loosened, and screw-bolts 32, 33 arranged in a slot 23 in the disc 14 are adjusted in jaws 24, 25 in the disc 14 and so move a block 30 secured to the wheel 12 relatively to the sides of the aperture 23 in the disc 14. When the block 30 is adjusted to bring the wheel 12 to the desired position, it is made secure in this position by the set-screws 21.
