Abstract: 19,344. Justice, P. M., [Plant, T. G.]. Aug. 23. Insoles, machines for.-In an insolereinforcing machine as described in Specif ication 27,876/07, in which a layer of canvas is applied to, and pressed down upon, the centre of a channeled sole while the lip of the channel is held away from the adhesive side of the canvas, the sole rests on a curved support 54, Fig. 5, and is held at the heel end by a sharpedged roll 55 carried by a spring- pressed lever 56 pivoted on a slide 59, and at the too end by a knife-edge 67 on a lever r pressed into position by a spring plunger 69. Protector frames 77, Fig. 3, are loosely mounted on a shaft 73, so as to turn and slide longitudinally. The shaft 73, which is rocked by arms 79 connected to a yoke 80 vertically reciprocated by a cam 46, Fig. 1, riding on a cam-wheel 42, imparts a swing- ing movement to the frames through arms 85, Fig. 3, fixed to the shaft, which are connected to rods 86 supported from the frames. The frames are moved towards and from each other at desired times by bell-crank levers 91, Fig. 1, which are operated by a rod 52 carrying at its lower extremity a cam riding on a cam-wheel 43. Each protector frame carries a series of rods 100, one of which is shown in Fig. 12. At its inner end is pivoted a pin or plate 101 to engage and protect the upturned lip of the channel. A slight amount of vertical play is allowed between the inner and centre arms 96, 97 of the protector frame and the rod, which is normally held depressed by a spring 110. Two collars 111, provided with pins 112 engaging a groove 113 slide on the rod, the outward limit of their movement being fixed by stops 116, which may be inserted at desired points in a series of threaded holes 115. A spring 114 tends to force the collars outwards. The protector at each side of the toe end of the boot is given a slight movement longitudinally of the boot in addition to its transverse movement, while the protectors at each side of the heel end may be rendered inoperative. A centring frame or presser 131, Fig. 3, mounted loosely on the shaft 73, is normally held in a raised position by a spring 133, but on depression of the protector frames, when in their contracted position, is engaged by projections 136 on the frames and brought down towards the support. Arms 137 on the presser carry at their ends spring-pressed plungers to engage the upper side of projections on the frames. The face of the presser has a flexible portion adapted to be moved transversely to adjust the presser for right or left soles. A treadleoperated one-revolution clutch connects a cog-wheel 37 on a shaft 3 with a driving-pulley 4, the shaft 3 making two revolutions for each one of the camshaft 39. In the operation of the machine, a sole is placed on the support 54 and the treadle depressed. The protector frames, which are initially raised, and in a contracted position overlapping the presser 131, are lowered on the work-support by the action of the cam 42 ; the cam 43 then extends the frames, causing the protector plates to grip the channel lip and the presser 131 to be set free to rise in response to its actuating- spring 133. The shaft 3 then stops, a piece of canvas is applied to the sole and pressed into the channel by a tool, the presser plate is depressed momentarily, and the machine is again started to lift and contract the frames to their original position.
