Abstract

661,044. Sole rounding and channelling. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Jan. 27, 1950 [Jan. 28, 1949], No. 2379/49. Class 17 (i). Machines for rounding, or trimming, the soles of lasted shoes have a chopping rounding knife 22, Figs. 2, 5, to which the work, which is held by the operator, is advanced step-by-step, by an oscillating feed arm 20, Figs. 1, 5, against an anvil on which the knife 22 operates, and an oscillating bottom rest 24. A U-shaped crease guide 28, Figs. 1, 2, 5, governs the relation of the sole to the knife at the shank, and a forepart guide F, Figs. 1, 5, 7, 8, having a work contacting surface corresponding in form to a portion of the rounded sole and furnished by an oscillatory,cam disc 160, Fig. 7, the edge face of a radial projection 161 on which provides a work guide member 162, is movable by contact or friction with the shoe upper to move the work relative to the knife 22 to determine the extents of sole edge projections at the forepart. The guides are operated in such a manner that at the two ends of the ball line, where control passes abruptly from one of the guides to the other, the control is continuous and there are in consequence no periods when the work may be subject to ungoverned manipulation by the operator and inaccuracies in the width of sole margin, due to uneven rate of feed of work, are avoided. In the preferred construction of machine, different widths of sole margin may be obtained by varying the contour of the periphery of the. cam disc 160 and the guides 28, F; function continuously to operate in succession upon right and left shoes of a pair, the guide F being held stationary by an electro-magnetically operated latch 194, under the control of the operator between the two operations and returned to initial set position, by a spring, to operate upon a further pair of shoes in succession after the second shoe of the preceding pair has been operated upon. The crease guide 28 is adjustably mounted on an arm 34 pivoted to the machine frame, its downward movement under gravity being limited by arm 40 pivoted to arm 34, while a stop 46, threaded into bracket 48, limits its upward movement. The forepart guide F is adjustably mounted in relation to a scale on a guideway 64 at the forward end of an adjustable section 60 of arm 58 pivoted on a shaft 50. Depression by operator of a treadle link 106, through arms 100, 96, shaft 94, arm 92, link 90, arm 86 and shaft 50, as the inside ball line approaches the operating point of knife 22, turns arm 58 in same direction to lower the guide F until a stop screw 108 arrests it, continued pressure on the treadle causing arm 100 to turn on shaft 94 against a spring 104. A roll 130 is rotatably mounted on a spindle 132 (not shown) guided for vertical movement, without rotation, in a block 134 which is adjustable by slot and screw connection relative to arm 80 of the guide F. This roll bears against one or other of three surfaces 122, 124, 126 of a disc 120 which controls the position of the crease guide, and its height is adjustable by turning spindle 132 by finger piece 140. Its position tangentially of these cam surfaces also is adjustable, by adjusting axis of the roll 130 which coincides with that of pivot shaft 50. A pin 144 secured in end of link 146 connected to an arm 100 by link 148 is engageable in one of a series of holes 142 in disc 120 to cause arm 34 and crease guide 28 to remain at rest or rise or fall gradually until guide F in its descent assumes control of width of sole extension and control passes from the guide 28. The disc 120 is moved gradually during the movement of the guide F to produce a gradual change in width of sole margin but, at the beginning and end of the gradual movement, it is moved abruptly to transfer control from one guide to the other. Depressions 128 at end of the active face 122, 124, or 126 free the arm 34 from the retaining action of the roll 130 leaving the crease guide 28 free to float in the crease without locating effect on the work. The work locating surface of the guide F is formed by arcuate peripheral edge of a member 162 on a radial projection 161 on the disc 160 which is mounted on a stud 156 on an adjustable supporting slide 68, which is guided in guideway 64 at the forward end of an adjustable section 60 of arm 58 mentioned above. Guides 164, 166 are provided, one on either side, for right and left shoes and these are radially and simultaneously adjustable to same extent by adjustable arm 176. Pressure of the work against edge guide 164, after latch 194 has been released to free the device F to rotate, due to the increasing radius of surface 164 lowering the work in relation to the knife 22. At the ball line the operator releases the treadle to operate upon the shoe shank and the device F is lifted by spring 82. The disc 120 is turned to raise the roll 130 from depression 128 and into contact with surface 124 to bring guide 28 into operation. Cam 126 operates to bring width of sole extension around outer side of forepart to that on inner side and gradually to that of the shank to the breast line. When the rounded shoe is removed from the guide F the depression 206 is engaged by latch 194 and guide is held stationary. The opposite shoe of the pair is then operated upon from the outside breast line to inside breast line, whereupon it is removed from the machine. As the member 166 moves out of engagement with the work, on release of the treadle, the disc 160 is rotated to its initial position by spring 184 to operate upon a succeeding pair. The machine may have a channelling knife 26 mounted on the block 24. Specification 13301/10, [Class 17 (i)], is referred to.
