Abstract: 9999. Lake, H. H., [Judd, E. C., and Cilley, H. E.]. April 21. Soles.-Improvements are made on the sole-levelling machine described in Specification No. 15,046, A.D. 1896. The main shaft 2 is driven by a belt and drives the secondary shaft 8 at a much reduced speed. The frame 16, carrying the shoesupporting jacks, is rocked by an eccentric 9 and rod 10, its amplitude of movement being adjusted by altering the position of the clamp 13 on the bar 15 attached to the said frame 16. The forepart roller consists of two conical sections 20 the inclination of whose axes can be varied by means of curved clamping-plates 108 and 109, Fig. 14. The yoke 19, carrying the roller-frame 23, is pivoted at the rear and is raised and lowered by means of a foot-lever 22 to which it is connected by a rod 21. The roller frame 23 is connected by a rod 24 to one arm of a bell crank 25 which is rocked by an eccentric on the main shaft. The shank-rollers 29 are constructed and mounted in a somewhat similar manner in a frame 28 adjustably connected to the yoke-frame 28<a>, which is raised and lowered by the foot-lever 22 through a rod. The frame 28 is connected to one arm of a bell crank 30 which is rocked by an eccentric on the main shaft and is mounted on one arm of a second bell crank rocked by an eccentric on the shaft 8. The movement of the said bell crank can be varied by adjusting the position of the clamps 35 on the arm 34. The rollers 29 are thus quickly vibrated while being moved slowly to and fro over the shank. The rocking frame 16 carries a laterally-adjustable bracket 41 on which the shoesupporting jacks are mounted. It, preferably, consists of two portions at right-angles to one another, so that one pair of jacks can be swung aside to have a shoe placed on them while the shoe on the other pair is being operated on. Each portion consists of an arm 42 provided with an undercut guide-piece 44 on which the dovetailbasis of the jacks can be clamped in any desired position. Fig. 4 shows, partly in section, the heelsupport. The base 46 can be clamped in any position on the guide 44 by a set-screw 51, and carries a transverse undercut guide 47 on which the base-plate 49 can be clamped in any position. From this base-plate rises a stem 50, to the upper end of which is jointed a jaw 61. In the latter is pivoted the jack-pin 63, which can be clamped at any desired inclination by the joint-pin 64. The lower part of the stem 50 is screwed to receive a nut 54, the upper face of which forms a thread or screw and abuts on the lower end of a sleeve 58 connected to the jaw 61 by a link 65. Thus, by rotating the nut 54, the pin 63 can be canted forwards or backwards. Slight modifications may be made on the heel-pin just described. Fig. 8 shows the toe-support and guide, which are adjusted longitudinally and transversely in a similar manner to the heel-support. The toe-support is raised and lowered by rotating the nut 77 on the screwed stem, and the guide is raised by a nut 81 which is rotated by means of a spur-wheel 80.
