Abstract: 2799. Kilb, G. J. Feb. 8, 1913, [Convention date]. Insoles, machines for. - A machine for operating upon reinforced insoles, having co-operating tools which act on the opposite sides of the rib to bend it substantially parallel with the face of the insole, is provided with an adjustable or other ironing - tool for setting the bent lip, and with means for relatively adjusting the tools in the line of work feed. The machine is also furnished with a knife for trimming the reinforcing-fabric at the shank; The tools for tightening the previously-applied fabric into the angles at the base of the lip comprise a disk 18, Figs. 1 and 2, and a rotary wheel 19, which also co-operates with a roll 1 to feed the work. The disk 18, Figs. 2 and 6, is furnished with a convex bottom 20, a peripheral edge 21 for tucking the fabric well into the inside angle of the lip, and a reduced stem 22, which is formed on a block 23 at the lower end of a rod secured by a nut 25 within a spindle 24. This spindle runs on ball bearings in a spring - pressed thimble 29 mounted in a sleeve 30, which is loosely carried by a cylindrical block 35 in a casing 36. The block is furnished with a stem 37, Fig. 5, which is rotatably mounted in a split clamp 38 slidable on a rod 39, Fig. 1, projecting from an arm 40 ; this arm is adjustably bolted to a frame 42 pivoted at 43 to the standard 5. The several parts are secured after adjustment by a butterfly nut 44, Fig. 5, on the stem 37. The wheel 19, Fig. 2, which is secured on the lower end of a shaft 45 driven positively by the gearing shown in Fig. 1, is provided with a toothed face 51 to engage the fabric on the feather of the insole and to assist in feeding the work, a vertical face 55 to engage the outer side of the lip, and a substantially horizontal face 56 to engage the upper portion of the outer side of the lip ; the face 51 is arranged so that its work-engaging face inclines towards the edge of the insole, and the work-supporting roll is bevelled as shown at 53 or 54, so that the feather is moulded down at an angle to the face of the insole. The reduced stem of the disk 18 co-operates with the faces 55, 56 in bending and setting the upper portion of the lip inwards substantially parallel to the face of the insole, and after the lip is removed from the influence of these tools, it is acted upon by a heated ironing-tool in the form of a bar 57, Fig. 4, which projects across the line of feed. This bar projects from an arm 58 bolted in a block 59, which is carried by a spring-pressed lever 60 pivoted on a bearing 46, Fig. 1, and the work-engaging face of the bar is bevelled so that the insole rib may readily pass beneath it and be additionally bent after leaving the setting-tools. The machine is also fitted with a trimming-knife 64, Fig. 4, the shank 65 of which is secured in a split block 67 clamped to the horizontal arm of a bent rod 69, the vertical arm of which is bolted to a bracket 70. The knife is adjusted so that it just clears the edge of the insole round the forepart ; but at the shank, where the width of the feather increases, the knife trims away the fabric along a line within the edge of the insole. The various tools, which are preferably heated, are held down to the work by a spring 72, Fig. 1; but to introduce or remove the work, the frame 42 can be turned about its pivot 43 by connexions 77, 76, 78 with a treadle.
