  • the present invention provides a machine in which a last on which a shoe upperis to be shaped is fixed in the machine in any well-known manner.
  • a simple rotarywiping means such as a driven roll is mounted for movement lengthwise along the margin of the shoe bottom to wipe the shaped upper inwardly Over an insole on the bottom of the last.
  • the wiping means is so mounted as to be movable widthwise Of the shoe to follow the peripheral contour of the shoe as controlled by a template.
  • the wiping means is also movable heightwise against the action of yieldable means to follow the heightwise contour of the shoe bottom. In this manner, no operator skill is required to guide the simple wiping means along the margin of the shoe and well-knownlocating means can be used to fix the lastin accurate location in the machine.
  • the axis of the rotary-wiping means is adapted to tilt to maintain a parallel relationto the shoe bottom to insure proper wiping conditions.
  • Another feature provides means for swingingsaid axis so the wiping forces are directed inwardly of the edge of the shoe regardless of the constantly'changing peripheral curvature of the shoe.

  • FIG. 10 is a side elevation of a portion of the mechanism shown in FIG. 9.
  • FIG. 11' is an end elevation in enlarged scale of the rotarywiping device of FIGS. 9'and 10.
  • FIG. 1 shows a machine embodying the invention for operating on a shoe comprising an upper 1 and an insole 2 which are assembled on a last'4'.
  • the upper has been tensioned previously by elements not shown and is held in tensioned condition against the last by members 5 and 6.
  • the lasting margins 9 and 10 of the upper are wiped inwardly over the opposite edges of the shoe bottom and are pressed against the insole bottom by rotary wiperscomprising wheels lland 12 which rotate in opposite directions as shown by the arrows in FIG. 1. Due to the friction between the wheels and the upper material, the'margins of the upper'are pulled sharply inward and. pressed downward against the insole 2.
  • the wheels 11 and 12 are guided in widthwisedirections along the-lastingmargins 9' and 10 by a template 57 (see-also FIG. 2).
  • the wheels are moved lengthwise along the periphery of the shoe bottom as guided by the template by movement of a slide 65 and adhesive applied to the insole bottom secures the upper to the insole in tensioned condition.
  • the wiping wheels 11 and 12 may be formed-of any resilient materialwhich is capable of exerting sufficient pressure but is sufficiently flexible so that a contact zone'is obtained which extends substantially across the lasting margins.
  • a simple means of extending the pressure range maybe provided by teeth formed on the periphery of the wheels. As shown in FIG. I the wheels are provided with teeth 14 which-are slanted so as to bend readily backward as the wheels are pressed against the lasting margin. The teeth bend progressively as they slide inwardly over the full width of the respective lasting margin, pulling the margin inwardly and pressing it against the bottom of the insole.
  • FIG. 3 Another form of resilient wiping wheel is shown in FIG. 3.
  • a wiping wheel 71 is provided with a plurality of pressure plates 72 each'pivoted for movement radially from the periphery of the wheel under the action of a spring 73.
  • the pressure plates 72 engage the lasting margin, first at theouter edge of the shoe bottom and then yield radially inward of the wheelunder the action of the springs 73 as they are dragged inwardly over the lasting margin. in this manner, the pressure of the springs 73 cause the plates to pull the lasting margin of the upper inwardly and press it firmly against the bottom of the insole 2.
  • other forms of wiping wheels may also be provided such as those having a periphery of undulated form or having a periphery formed of bristles such as in a rotary brush.
  • the wiping wheels are moved lengthwise along the margin of the shoe bottom by movement of the slides 65, 66, they must also move heightwise to follow the heightwise curvature of the shoe bottom.
  • the wheels 11 and 12 are mounted on shafts l7 and 18, respectively, which are rotatable in bearing blocks 19 and 20.
  • the blocks are formed on the lower ends of plungers 21, 22 which are mounted for heightwise sliding movement in sleeves 23 and 24.
  • the blocks and hence also the wheels 11 and 12 are urged downwardly by springs 29 and 39 mounted on the sleeves 23 and 24 respectively.
  • the upper ends of the springs engage the underside of arms 58 and 59 from which depend the sleeves 23 and 24.
  • the springs are designed so as to provide a substantially constant force over a range of movement so that the wheels 11 and 12 are pressed against the upper margin with a substantially uniform pressure as they follow the heightwise contour of the shoe bottom. It should be understood, however, that a substantially uniform pressure could also be obtained by using weights which urge the wheels downwardly by the force of gravity rather than by using the springs as shown.
  • the wiping wheels 11 and 12 as seen in FIG. 1 are driven in their respective directions by motors 44 and 45 through belts 53, 54 which run on pulleys 46 and 48.
  • the motors are mounted on supports 55, 56 on the upper ends of the plungers 21, 22, respectively.
  • the ends 60, 61 of the arms 58, 59 slide along opposite sides of the template 57 so that the wheels 11 and 12 are moved back and forth widthwise as they are moved lengthwise to follow the peripheral contour of the shoe bottom.
  • the arms 58, 59 which carry the wheels are mounted for widthwise swinging movement on bolts 63, 64 respectively (FIGS. 1 and 2) which are carried by the slides 65, 66.
  • the slides rest on bearing plates 69, 70 and are guided for movement lengthwise of the shoe by guideways 67, 68, respectively.
  • the lengthwise and widthwise swinging movements of the arms are illustrated in FIG. 2 with only the arm 58 being shown.
  • the slides 65 and 66 are moved lengthwise of the shoe in the direction of the arrow (FIG. 2) in any convenient manner, such as by means of a piston and cylinder device, not shown.
  • a spring 62 which extends between the support plates for the motors 44 and 45 urge the arms 58, 59 inwardly so that the surfaces 60 and 61 of the arms maintain continual engagement with the periphery of the template. It should be apparent that the machine could be provided with only one wiping wheel rather than the two illustrated in FIG. 1 without departing from the scope of the invention. ln this respect, the arm carrying the single-wiping wheel could be guided first toewardly along one side of the template and then heelwardly along the other side.
  • a nozzle associated with the wiper wheel 11.
  • the nozzle 74 is formed on the lower end of a feed pipe 76 which is mounted for heightwise sliding movements in the support block 20 for the wiping wheel 12.
  • the nozzle is urged down into yieldable engagement with the insole bottom by a spring 81 compressed between a collar 79 on the pipe and the underside of the block 20.
  • the upper end of the feedpipe is connected by a flexible hose 83 to an adhesive container 78 which supplies adhesive to the nozzle.
  • the lasting margin of the upper is wiped inwardly over the insole by the wiping wheel 12, it is pulled over the cement nozzle 74 and the cement flowing from the nozzle secures the upper to the insole bottom as the wiping wheel is moved progressively along the shoe margin. Since the nozzle is mounted on the bearing for the wiping wheel 12 it follows the movement of the wheel as it follows the contour of the shoe bottom. In this manner, the application of adhesive is combined with the operation of wiping the upper margin so that a separate operation for the application of cement is eliminated. As seen in FIG. 4 this arrangement is particularly suitable for securing the upper margin especially in the ball and shank area.
