Definitions

  • This invention herein to be described relates to sole-sewing machines and more particularly to machines of the kind having an arcuate-shaped needle, oscillatable in the direction of the arc and an awl of similar shape and oscillatable around the same axis, which awl is considerably shorter and somewhat thicker and thus more resistant to bending than the needle.
  • One object of our present invention relates to improvements in our prior sole-sewing machine and is, to provide a new and useful operating lever provided with a toothed segment for the two tools, each tool holder having a toothed se ment which are adapted, by lateral movement, to mesh in reliable manner alternately with the segment on the lever.
  • Fig. l is a side view, partly in section on the line AB of Fig. 3, showing the needle and awl holders and pertaining parts of a sole-sewing machine embodying the invention and further showing the parts in one working position with the awl piercing the Work or sole and the needle retracted;
  • Fig. 2 is a similar view to Fig. l, but showing the parts in another working position with the needle penetrating the work or sole and the awl retracted;
  • Fig. 3 is a plan view of the mechanism with the parts in the position shown in Fig. l.
  • the awl a and the needle 22 are each clamped in a holder or carrier consisting of two clamping jaws.
  • the awl holder 0 has a toothed segment I on its rear edge and is fixedly mounted on a rock-shaft or spindle d the axis of which forms the axis of oscillation of the awl holder.
  • the needle holder 2 has a toothed segment 3 on its rear edge and is freely mounted, closely adjacent the awl holder, on the hub 2' of said awl holder.
  • the rock-shaft d is rotatably and longitudinally displaceably mounted in the bearing 1 (Fig. 3) and in the hub 4 of the work-presser g, which hub is itself rotatably but not displaceably mounted in the bearing h.
  • a screw t having an eye u
  • the lever in is formed as a rockinglever although for the sake of simplicity, it has not been so shown in the drawing.
  • the toothed segment I on the awl holder 0 and the toothed segment 3 on the needle holder 6 alternately mesh with the toothed segment 6 of the common operating lever 9 oscillatably mounted on the stub shaft 1 of machine-frame 3.
  • the needle holder 6 has an opening M in which is engageable a stop-bolt I5 mounted in the bearing 7.
  • the small clamping jaw of the awl holder 0 facing the work-presser g lies in line with, but behind, the said presser g.
  • the needle holder e is then swung into the position shown in Fig. 2 and immediately withdrawn, the needle I) passing through the hole formed in the work or sole q by the awl a and through the hole n of the stitch-plate 0, thereby forming a stitch.
  • the oscillations of the awl holder 0, l and needle holder e, 3 are controlled by longitudinal movement of the rock-shaft d, which movement is efiected by means of rocking-lever m.
  • This lever effects alternately the meshing and unmeshing of the toothed segments I or 3 of the holders 0 or e with the toothed segment on the oscillatably mounted operating lever 9.
  • the opening I4 on the needle holder 15 again engages on the stopbolt [5 mounted in the bearing ,f, to hold the needle holder 6 in retracted position.
  • a pair of laterally spaced tool holders oscillatable on a common axis a Work support having a tool receiving opening, means for moving said holders simultaneously along said axis to bring the tool holders alternately into operative position in a plane of oscillation passing through said opening, a toothed segment on each of said tool holders, an oscillatory operating lever pivoted to oscillate in a fixed plane and having a toothed segment wherewith each of the segments of the tool holders alternately meshes when the respective tool holder is moved into operative position, and means to restrain one of said tool holders from operation upon the other tool holder being in operative position.
