Definitions

  • the prior art has used sewing machines constituted essentially, on the one hand, of a fork provided with a guiding roller, and, on the other hand, of a vertical needle which comes to grasp between the arms of said fork and through the sole a double yarn from above, and, on the other hand, of a horizontal hook or divider which during upward movement of the vertical needle grasps, in its turn, one of the strands of the double thread, and and also of a circular netting needle whose hook drives the uppermost yarn from inside the loop of the lower yarn thus formed by the operation of the vertical needle and of the horizontal divider, the stitch being terminated when the vertical needle comes back through the sole to meet again the lower double yarn.
  • the present invention relates to an assembly constituted by a sole for an article of footwear which can be sewn to the upper along the entire periphery including the heel, and to an attachment for an ordinary sewing machine permitting such sewing with such a machine.
  • the sole according to the invention is characterized by a continuous groove, moulded straight on the front part of the sole helically or in gimlet fashion on the flanks of the arch support and obliquely on the heel which makes it possible to sew said sole along its entire periphery with the upper of the article of footwear.
  • the present invention is an advantageous substitute, from the point of view of robustness, to gluing.
  • FIG. 1 is a view of an ordinary machine for sewing so es.
  • FIG. 2 is a view taken along arrow F of a horizontal divider for a vertical needle.
  • FIG. 3 is a view of the device according to the invention, the vertical needle being in its upper position.
  • FIG. 4 is a perspective view of the attachment.
  • FIG. 5 is a perspective view of the attachment according to the invention in lowered position of the vertical needle.
  • FIG. 6 is a cross sectional view of a sole according to the invention.
  • FIG. 7 is an underneath view of the sole.
  • the sole S having a toe portion, a heel portion and an intermediate portion interconnecting said toe and heel portions and which is constituted by its arch support 26 and its heel 25 the inner surface of which has various shapes such as grooves 28 which can be placed by squares, circles, teeth or striations.
  • peripheral groove 24 is made during moulding and extends along the entire contour of said sole. It begins straight and perpendicular to the general plane of the sole along the toe portion and continues still straight and perpendicular to the sole under the balls of the feet at d.
  • support g starting from point e at the intermediate portion it follows a twisting helical path and inclines obliquely inwardly and upwardly around the heel 25 in the heel portion It all around said heel up to c.
  • the new product constituted by the sole according to the invention cannot be confused with vamped soles which overlap the upper level of the first mounting thus covering a part of the lower plane and whose coating can be sewn by another process.
  • the assembly consists essentially of a fork 1 having two arms 1a and 1b which can be provided with a small guiding roller 2 freely mounted in a vertical shaft, a support 3 on which is passed the shoe which is to be sewn, and which is constantly urged along the guiding roller 2.
  • the fork is made rigid with a support 4 which can be separately or simultaneously driven vertically (arrow V and arrow W).
  • the assembly comprises additionally a needle 5 provided with a hook 6 which also can be driven vertically in one direction or the other; and of a hook or divider 7 which can be driven horizontally in one or the other direction (arrow X).
  • the assembly also comprises a device functioning as a rotating neeting needle, and constituted by a ring 8 in which rotates according to arrow Y a movable crown 9 having hook 10 while the above thread or yarn 11 issues from a fixed arm 12 through opening 13.
  • the lower thread 14 which needle 5 will grab issues from a lower bobbin through foot 3.
  • the device of the invention is adaptable to a sewing machine of known design such as that above described, as can be appreciated by referring to FIGS. 3, 4 and 5.
  • fork (FIG. 1) has been replaced by a rod 17 which also has a forked extremity 1-8 downwardly opened and whose broach 19 is banked.
  • a tube 20 having a slot 21 in which movesa similarly banked U- shaped member 22 whose branch 23 can at the end of its movement reach the same height as extremity 18 of rod 17.
  • a substantially planar sole for an article of footwear comprising: a toe portion, a heel portion, and an intermediate portion interconnecting said toe and heel portions, means defining a groove extending peripherally around said sole; and wherein said groove extends perpendicularly to the plane of said sole along said toe portion and obliquely extends inwardly along said heel portion.
