Abstract: 23,964. Justice, P. M., [Plant, T. G.]. Nov. 9. Insoles; paring. - Relates to a machine for applying reinforcing- material to insoles &c. The insole and reinforcing-material are fed forwards between a depressible work-supporting roller 5 and an inclined roller 21, which consolidates the outer edge of the insole, by a step-by-step motion derived through a Horton clutch 12 and an eccentric 16 from a driving-pulley 18. A tucking-tool 26 is carried by a double arm 25 pivoted to the head 2 of the machine so as to have a motion parallel to the inclined surfaces of the channel. Between the members of the double arm 25 oscillates an arm 27, its motion being communicated through a link 28 to a knifecarrier 29. The carrier 29 has a portion 30 adapted to reciprocate in a member 31 fixed to the head 2, and a shaft 32 extends into the bore of the consolidating-wheel shaft 20 to ensure rectilinear motion of the carrier and its knife 37. The consolidating-wheel 21 is hollowed to receive the member 31, which carries a cutter block 35 co-operating with the reciprocating knife 37 to trim off surplus reinforcing - material. The motion of the tools 26, 37 alternates with the feed of the work. The tools are arranged vertically above each other in order to operate in the same plane transversely of the insole thus preventing distortion of the work. They are operated by eccentrics 38, 39 on the main shaft, which are coupled to pins 42, 50 having eccentric heads which permit adjustment of the tools. These pins are preferably clamped in the split ends of the arms 25, 27. Figs. 7 and 8 show means for adjusting the knife 37 and the tucking-tools 26 respectively in their carriers. The knife 37 slides in a dovetail groove in its carrier 29, a screw 68 fixing its position, and clamping-means 69 being provided. A removable plate 70 is secured on the arm 25 in the rear of the tucking-tool 26, and carries an adjusting-screw 71 ; this bears upon the tool, which is clamped by a screw 72. To ensure that the reinforcing-material takes a substantially vertical position between the tools and the consolidating-wheel, guides 52, 54 are fixed to the head 2 so as to act in advance of the tools. The outer guide 54 has an inner face 55 slightly outwardly inclined, and a toe 56 directed downwards into the channels of the insole, to guide the reinforcing-material into the channels. It is adjustably held in position, for example by a screw 59. The inner guide 52 has a toe 60 (extending beneath the consolidating- wheel 21 almost to the lowest point on its periphery), a vertical portion 61, and an horizontal portion 62, having a convex edge 65 merging into a substantially straight edge at the toe 60. The flat portion 62 engages the surface of the insole, outside the channel lip to prevent the knife 37 from clipping the corner of the lip at its rear end as it leaves the machine ; it serves also with the vertical portion 60 to throw the reinforcing- material upwards between the face 63 of the cutter-block carrier and the face 55 of the outer guide 54. The guide 54 serves to smooth out the reinforcing-material on to the surfaces of the insole in advance of the tools, and prevents puckering. A table 66, having an opening to receive the worksupporting wheel 5, is fixed to the work supporting block to rise and fall therewith. The guides 52, 54 serve by engaging opposite sides of the channel lip, to guide the work through the machine, which runs at a relatively high speed. Further, the convex edge 65, by engaging the exterior of the lip when operating on the concave portions thereof, and the toe 62 when operating upon the curves at the toe, serve to prevent the work from leaving the tools. The guide 52 may be adapted to engage also the edge of the insole.
