Patent GB-317129-A (GB)
Abstract: 317,129. Dunlop Rubber Co., Ltd., Murphy, E. A., and Twiss, D. F. May 12, 1928. Latex, treating.-In order to obviate the disadvantages due to the persistence of air or gas bubbles in dispersions, emulsions or solutions containing indiarubber or similar materials during the manufacture of articles by dipping of non-porous formers, spreading, spraying or by electrophoretic processes, fluid pressure is applied in one or more stages of manufacture. Air bubbles may be entrapped in latex during concentrating or compounding and the application of pressure thereto is stated to force the air into solution. In the case of articles produced by dipping non-porous formers which are subsequently heated, the application of pressure also prevents blistering due to the formation of steam. Undesirable effects due to occlusion of gases at the surface of a former or mould or due to evolution of gases by the action, on the deposit or the former, or of an acid or saline coagulating solution are also avoided. The pressure may, in all cases, be maintained until the deposit has become tough.

Title: Improvements in or relating to shoe upper conforming machines
IPC: A43D21/12
Filed: 1962-08-22
Abstract: 1,011,730. Boots &c. BRITISH UNITED SHOE MACHINERY CO. Ltd. Aug. 22, 1962 [Aug. 23, 1961], No. 32178/62. Heading A3B. A machine for lasting heel end and waist portions of a shoe has power operated heel wipers, a shoe support, a heel band and waist lasting instrumentalities. The construction and operation of the shoe support, heel band and heel wipers is as described in United States Specification 1,770,976 except that the treadle, used to raise the shoe support from a loading to an operative position, is replaced by a lever 36 operated by a piston and cylinder 32 (Fig. 1). The waist portion is lasted by two grippers 72 and two wipers. The grippers 72 are raised and lowered by a piston and cylinder 64 and are closed by a wedge 108 on a piston rod 94 (Fig. 15). A sprung sleeve 120 on each gripper acts as a hold-down during tensioning. The waist wipers are mounted on a slide 162 (Fig. 6), the heelward end 168 (Fig. 13) being rigidly secured to the slide 162 and the toeward end 174 being adjustably mounted on the slide 162 and connected to the heelward end 168 by chain links 170 which are forced down by a helical spring 180 and leaf springs 192. The heelward ends 168 of the waist wipers extend beyond the toeward limit of the heel wipers, but are shaped so that they lie clear of the heel wipers at the end of their inwiping operation. As the slide 162 (Fig. 6) is moved in by the piston and cylinder 200, it can yield heightwise against the spring press 230 until the incline 236 reaches the roll 234 (Fig. 6) when the slide is locked against heightwise movement. The machine is started by moving a twoway switch 320 to its first position which lowers piston 30 (Fig. 16) to move the shoe support to its operative position. On moving the switch 320 to its second position the piston 66 is lowered to lower the grippers 72 which, at the end of their downward movement, operate a limit switch to lower piston 92 to close the gripper jaws. A sequence valve 344 then raises the grippers and a pressure switch 450 moves in the waist wipers. A pressure sensitive diaphragm 361 then opens the gripper jaws and the waist wipers complete their inward movement to operate switches 460, 462, which operate a piston 40 to engage a clutch on the main drive shaft 22 (Fig. 1). One revolution of the shaft 22 drives the shoe support, heel wipers and heel band through one cycle of operations as described in the above-mentioned Specification. At the end of this cycle a cam driven switch 474 stops the machine, and returns the various parts to their initial positions. Specification 235,286 is referred to.
