Abstract: 260. Cook, M. Jan. 4. Embossing ; stamping.-The channel lip of the inner sole of a welted boot or shoe is cut off at points a where the welt is to terminate, and at the same time, size and guide marks are stamped on the sole by means of a machine which consists of a frame 4 pivoted on studs 3 at the sides of a base 1. Incising-knives 5 are mounted on brackets 6 which are pivoted to the frame and are secured in position by clamps 12 carried by rearward projections 11. The brackets are adjusted laterally by oppositely-pitched worms 15, mounted on a shaft 13 which is turned by a hand-wheel 14 engaging with rolls 17 carried by the brackets. The frame is oscillated by means of an eccentric, and a hand-wheel 24, working on a screwed bar 22 connecting the frame to the eccentric strap, enables the approach of the knives to the bedplate to be regulated. An indenting marker 26, carried on the forward part of the frame between and in line with the cutters, makes a mark 3 on the sole which will serve as a guide to the operator in trimming off the welt. The knives are held to the brackets by clamps 29 and may be adjusted to compensate for loss in grinding by screws 27 which have collars 28 entering grooves in the rear side of the knives. A stationary marker 30, immediately below the marker 26, forms an indented line to serve as a guide for positioning the canvas layer which is cemented to some classes of inner soles. Side gauges 31, 32 are clamped to a block 35 which is screwed to a bar 37 sliding through the base. Two other side gauges 33, 34 are similarly connected to a bar 38. The bars are toothed and gear with a pinion placed between them, so that a movement of one bar causes an equal movement of the other in the opposite direction. A spring causes the gauges to grip the sides of the sole to be operated on. The sole is pushed heel first between the gauges, and is passed under a bridge piece to prevent buckling. The end of the sole is stopped by a gauge 44 which may be adjusted in the direction of its length by means of a worm keyed to a shaft turned by a knob 48. In order to mark on the soles numbers representing sizes, an index 52 and a disk 53 bearing marking- dies on its periphery are carried on the worm-shaft. The dies project slightly through the supporting surface and make an impression on the sole when it is pressed against them. The disk is keyed to a sleeve projecting from the index so as to turn with it, and the index is connected to the worm shaft by means of a latch pivoted to an arm 57 and engaging with notches in the rim of the knob 48. Thus, when the knob is turned to adjust the gauge 44, the marking-dies and index are also turned. A second disk 59, mounted beside the disk 53, carries marking-dies which represent letters for indicating the widths of the soles. This disk is mounted loosely on the worm-shaft and is turned by a bar 61 pivoted to it and held in place by a detent, as shown in Fig. 2. The sole is pressed against the dies by a yielding presser 64 which covers both dies at once. The latch connecting the index to the knob 48 allows the index to be turned without turning the worm-shaft. By this means the cuts in the channel lips may be made at varying distances from the heel in shoes of the same size.
