Abstract
680,933. Boot machines. BRITISH UNITED SHOE MACHINERY CO., Ltd., and GUDGER, J. May 8, 1951 [May 9, 1950], No. 11478/50. Class 17 (i). A machine for making a plurality of slits in the lasting margin of a shoe upper at the curved end portions according to the method of Specification 623,657 operates while the shoe is on a last and after a preliminary tensioning operation and comprises means to engage the shoe bottom to determine the depth of the cut inwardly from the edge of the upper as it is fed stepwise past a slitting device. A shoe on a last is held against a bottom rest 13 having a substantially vertical face, bent to a U-shape in plan, for engaging the shoe bottom thus determining the depth of the cut. A pair of feed rollers 15, 16 (not shown), are rotated intermittently to give a stepwise feed to the upper over a shear block 5 by mechanism similar to the prior Specification. The roller 16 may be raised to insert the upper by depressing a link 29. A knife 39 oscillates as in the prior Specification to effect the slitting of the upper which is held against the shear block 5 by a presser member 61 operating in timed relation with the knife and feed mechanisms. Specifications 470,749 and 660,036, [Group VIII], also are referred to.
