    Abstract: 10,809. Stewart, W. C. May 10, 1906, [date applied for under Patents Act, 1901]. Insoles. - Relates to a machine for slashing insoles to render them more flexible, and particularly adapted for welt insoles, in which the slashes must not extend to the usual channel. The machine is adjustable for any insoles, irrespective of their size or width, and whether they be rights or lefts. To enable the length of the slashes to be varied according to the variation in the width of the insole, or in the distance between the channel lips of a welt insole, at different parts, the slashing-knife is given two operative movements for each feed movement, and, by an automatic transverse movement of the knife, the overlapping of the two slashes is varied as required. Fig. 10 shows diagrammatically a slashed insole, in which one cut of each pair is represented by double lines a, and the second cut by a single line b, the amount of overlap varying according to the contour &c. of the insole. The knife 18, Figs. 3 and 4, is adjustably mounted between clamping-jaws in the holder 17, which is capable of transverse movement in the guide-plates 16 fixed to the slide 14. This slide is reciprocated, to operate the knife, by an eccentric on the driving - shaft 2, the eccentric-rod being connected to the slide by a ball- and - socket joint, and screwing into the eccentric strap, to permit of its adjustment. To effect the transverse movement of the knife, the holder 17 is connected by a link 21, Fig. 7, to the arm 22 of the three-armed bell-crank 22, 25, 26, the arm 26 being connected under the control of springs 30 to the sliding rod 28, which is reciprocated by the crank 31. The operative movement of the link 21 is restricted by the arm 25, through the mechanism shown in Fig. 5, so that the transverse movement of the knife is automatically adapted to the requirements of the work. The arm 25 is connected under the control of springs 75 to the sliding rod 71, which has a bent end engaging between the wedge-shaped blocks 68, 69, Figs. 5 and 7. These blocks are connected by links 67 to the pivoted spring-connected arms 64, which are provided with feelers 65 adapted to engage the margin of the insole, as shown, or the channel lip. As the insole passes between the feelers, the blocks 68, 69 are moved apart or towards each other according to the variations in the contour, and thus determine the movement of the rod 71 and, consequently, of the knife, the surplus movement of the rod 28 being taken up by the springs 30. The insole is inserted between the feed-roller 37 and the pressure roller 38, Fig. 4, up to the stop 57 on the pivoted arm 58. A treadle is then depressed, which, through the rod 56 and lever 55, lowers the flexing-roller 54 to bend the insole over the curved anvil 36, so that the knife acts on the convexed upper surface of the work. The Iressure roller 38 is normally held up by the pin 52 on the arm 53 of the flexing-roller, until the latter is depressed by the treadle against the action of the spring 57, on which the roller 38 is forced into engagement with the work by the springs 51. On the downward movement of the flexing-roller also, the ear 62 engages the arm 61 of the stop 57x, and raises the stop clear of the work. The feed-roller is driven intermittently through a, preferably, roller clutch, which is actuated by a block on the rod 43, Fig. 7, coupled to the rod 28. The return movement of the clutch actuator is limited by a stop, which can be adjusted to limit the stroke and, consequently, the amount of the feed movement. A similar clutch 46, Fig. 3, is provided at the other end of the roller to prevent any return movement. Means are provided for automatically stopping the machine after a given number of effective movements. The driving - pulley 3 is coupled to the shaft 2 by a suitable clutch, that shown in Fig. 3 being a roller clutch in which the roller cage 7 has a projecting lug 10 adapted to be engaged by the spring-controlled stop-hook 78. This hook is mounted on a pivoted arm 80 engaged by the forked end 87 of the lever 86x, which is connected by the toggle-links 90 to the arm 91 x of the flexing-roller. The toggle-joint is normally supported by the block 93, and, when the tread!e is depressed to start the machine, the pin 91 at the joint is raised into the seat 94. On the frame is mounted a rack-bar 95, which is raised step-by-step by the crank-pin &c. 100 engaging the teeth 99, the ratchet-teeth 101 at the lower end of the bar being engaged by the pawl 103, to prevent return movement. The bar 95 has at its lower end an adjustable block 102, which, on the upward movement of the bar, ultimately displaces the pin 91 from its seat, so breaking the toggle-joint, and causing the stop-hook 78 to come into action, even if the treadle be held depressed. The transverse reciprocation may be imparted to the work instead of to the knife.

    Abstract: 24,683. Stewart, W. C., and Hooper, W. H. Nov. 20, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Ornamenting; heels.-A machine for beading and knurling or otherwise operating upon heels is provided with an endless flexible belt, band, or strap to hold, or to assist in holding, the work up to the operating-tools. The beading-tool 5, and the knurling-wheel 6, Fig. 3, are mounted on the forward end of a shaft 4 journaled in a forked machine-head 2 and driven by a belt 9 from a countershaft, which is provided with usual treadle controlling - means. The flexible belt &c. 10, Figs. 1 and 3, passes freely through a two-part tubular holder 11, 12 jointed at 13 in the upper end of a three - armed lever 14 pivoted on the machine head. One arm of this lever is connected to an adjustable spring 16, which tends to hold the holder in the position shown in full lines in Fig. 1, while the other arm of the lever is connected ihrough a rod 18 to a treadle ; on the depression of the treadle, the belt is relaxed, as shown in dotted lines in Fig. 1. The two parts of the holder 11, 12 are separated by a spring 19, and each part is provided with a movable top wall held in place by a blade spring. To assist the belt in holding the heel up to the tools, there is provided a top-lift plate 28, Fig. 3, universally-mounted on a slide bar 29 located in an adjustable sleeve 30. A spring 33 tends to force the plate to the left, Fig. 3, and also to square it relatively to the bar 29. The bar 29 is connected up as shown to the treadle rod 18, so that, on the depression of the treadle to release the belt &c. 10, the plate 29 is also withdrawn from the top lift ; this facilitates the removal or insertion of the work. The machine is also fitted with a brushing-up wheel 42 located at the back and somewhat to the left of the beading- wheel. The wheel is driven by the belt 9 running over an idle pulley 45 and the driving-pulley 44.
