Title: Improvements in or relating to machines adapted to apply levelling pressure to bottom portions of shoes
IPC: A43D89/00
Filed: 1948-07-15
Abstract: 639,650. Sole-levelling machines. BRITISH UNITED SHOE MACHINERY CO., Ltd. July 15, 1948, No. 18996. Convention date, July 16, 1947. Addition to 543,547. [Class 17 (i)] Stubbing of a shoe toe against the levelling roll of the machine of the parent Specification, if that machine is operated too speedily, i.e. without giving time for the fluid pressure to build up to operate the roll-lifting means, is avoided by providing mechanism which is capable of very rapidly rendering the rolllifting means operative in response to the initial rearward movement of the shoe support, so that the roll will be lifted against the action of its springs before the toe end of the shoe moves under the roll. A control member 122 for the lifting mechanism, which is described in the parent Specification, is urged into pressure-applying position by a spring 106 and a latch 120 holds the control member 122 against the action of the spring 106 in a position in which, when the shoe support is in its forward position, it is ineffective to operate the lifting mechanism, i.e. the toggle 96, 98 is broken. The latch 120 is arranged to be released quite early in the rearward movement of the shoe support by a rod 122, and, during the forward movement of the support at the end of a levelling operation, means controlled thereby moves the control member 122 back into its ineffective position in which position it is held by the latch. At any time during the levelling operation the treadle 164 can be used to impart rearward movement to the rod 122 to operate the valve 86 by which the roll-lifting means may lift the roll 14 against the action of the springs 58, 60.
