Title: Improvements in or relating to methods of, and machines for, operating on platform covers of platform shoes
IPC: A43D85/00
Filed: 1945-12-17
Abstract: 605,151. Boots and shoes. BRITISH UNITED SHOE MACHINERY CO., Ltd. Dec. 17, 1945, No. 34057. Convention date, Dec. 4, 1944. [Class 17(i)] The cover of a platform shoe is turned from a position in which it lies against the shoe upper to a position in which it projects beyond the bottom edge of the upper to receive and cover the platform edges, by engaging a tool between the cover and the shoe upper and producing relative heightwise movement between the tool and shoe, preferably by moving the shoe relative to a fixed tool. In the form shown, two tools 20, 22, each comprising a resilient blunt edged U-shaped member curved respectively to the toe and heel ends of the shoe, are mounted on a slide 52 movable manually by the operator, transversely on a guide 58 carried by a shelf 30 on the machine frame to bring them successively under a plunger 24 which engages the platform and serves as an abutment to move the shoe and platform cover relatively to the tools. These tools are sufficiently resilient to enable them to fit shoes of different shapes and sizes, and are supported so as to leave the ends of their limbs free. A tool 26 pushes the shoe forwardly to enable the tools 20, 22 to clear the projecting part on the cover at the junction with the upper and to drag on and tension the cover during the turning operation. The plunger 24 comprises a U- shaped plate pivoted on a pin 60 in such manner that, when the plunger engages the shoe bottom, a spring 71 in the bore of a bell crank arm 62 yields, and a forward thrust is imparted to it. The tools 20, 22 are operated in succession on the ends of the shoe by depressing a treadle 102 to cause a ratchet bar 92 to engage a block 84 and draw a link 96 downwardly. Links 118 also descend and a spring 112 draws a lever 68 which carries the plunger 24 as far as is permitted by the inner end of a slot 120 at a faster rate than the link 96. After the plunger engages the shoe bottom,. it is forced downwards to cause the tool to turn one end of the cover. The tool 26 is advanced by downward movement of the limbs 78 and by forward movement of a cam 126 to engage the rear surface of the platform and push the shoe forwards during the early portion of des- , cent of the rolls 130. It also tensions the cover by pressing it against the tool under the action of a spring 132. A stop screw 108 affords adjustment of plunger 24 according to the thickness of the midsole and heel. A modified arrangement is described in which the tool 26 may be adjusted to exercise little or no pressing action on the cover and the extent of forward thrust also may be varied.
