Title: Improvements in or relating to fastener-assorting mechanism suitable for use in the manufacture of boots or shoes
IPC: A43D71/02
Filed: 1946-02-01
Abstract: 607,378. Nailing machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., KEALL, F. B., and FREER, C. H Feb. 1, 1946, No. 3211. [Class 89(iii)] A fastener-assorting mechanism comprises a raceway having a passage therein for supporting a row of fasteners, a fastener-separating device movable laterally of the passage to separate the endmost fastener, and a fastenerengaging device which engages one side of the head of the endmost fastener to prevent lateral movement thereof with the fastenerseparating device. In a machine for feeding tacks singly, tacks from an inclined raceway 1 are separated by a slotted block 11 carried by a lever 9 pivoted on a stud 7, and are held against lateral movement with the block 11 by a slidable member 27 having a down-turned end to engage the tack head. The block 11 has a slot 19 for the tack shank, a recess 21 for the tack head and a hole 23 through which the tack passes on completion of a stroke. Another raceway 3 carrying tacks of a different size is provided with a similar separator block 55 and the tacks are held against lateral movement by a pivoted blade-like member 51. Operation of the separator blocks 11. 55 is effected by a cam-operated lever 65 acting through pivoted fingers 79, 81 to rock the arms 9 (through levers 45. 41) and 59 (directly) against springs 33. One or other of the fingers 79. 81 is moved to engage its lever by a pin 97 on a link 95 slidable by a manually operable eccentric 93. When a tack is released through the hole 23 it passes through a hole 25 in the raceway and down a tube to the usual tack block. As applied to the lasting machine described in Specification 14,433/97. [Class 89]. the gripper 119 is movable to either side of the tack block bv a manually operable eccentric 123 to allow for operation on opposite sides of a shoe. In a heel seat or toe lasting machine in which tacks are simultaneously separated from a row of raceways separator blocks 155, Fig. 16, and tack stops 185 are mounted respectively on bars 167, 183 connected together by screws 191 and inclined slots 189 (not shown), the bars being provided with co-operating inclined surfaces 193, 194. When the separator bar 167 is moved longitudinally relatively to the tack stop bar 183, the latter is lowered to engage the stops 185 with the slots 159 and moved forwardly to hold the tacks against movement with the blocks 155. Longitudinal movement of the bar 183 is prevented by a ball-ended link arrangement. Specifications 28,474/10, [Class 89(iii)], 391,451 and 470,749 are referred to.

Title: Improvements in or relating to the extrusion of synthetic linear polymers
Inventor: JAMSETT RONALD ALFRED
IPC: D01D1/04
Filed: 1954-02-09
Abstract: <PICT:0752665/IV(a)/1> Synthetic linear polymers are melt-spun in an apparatus comprising a chamber having a heated melting-grid, water vapour being injected into the chamber at a point near the vertical axis of the chamber and above the grid.  It is stated that water vapour so introduced is more effective in excluding air from the melt chamber, and so preventing degradation of the molten material, than when introduced in other positions.  The water vapour may be introduced from a steam main at 25 lbs. per square inch, the pipe having an outlet 0.06 inch in diameter.  As shown, flaked polymer is dropped into the chamber 3, which is jacketed at its lower end and has hollow fins 9 communicating with the jacket.  A heated mixture of diphenyl and diphenyl oxide is circulated through the jacket and fins.  Water vapour is introduced from the steam pipe 17 having its outlet 21 near the vertical axis of the chamber and above the fins 9. Molten material passes into the melt pool 11 and, by way of pump 13, to spinneret 15.  The end 21 of the steam pipe, instead of being directed upwardly as shown, may be directed downwardly or sideways, and may take any desired form, e.g. a nozzle.  Specifications 653,757 and 732,130 are referred to.
