Definitions

  • the object of the invention is to provide improved means for sewing by machine the uppers of veldtschoen to their soles in cases where the upper is not fully, if at all, lasted and, during the sewing operation, it is required to bring the outwardly turned margin of upper snugly into! the angle formed by a last and the projecting :margin of the shoe sole thereon and to bed the upper on to said margin to be secured there by the stitching.
  • the needle segment of the machine has fixed in it directly in front of the usual needle 2 a second similar needle 4.
  • the needles which are concentric and in the same plane are spaced apart a distance accord- 55; mg to the desired distance apart of the lines of than in machines of this type when arranged to form a-single seam, so as to adequately support the needles while they pierce the work, and to accurately position them for the looping of the threads round the needles.
  • the work support It hasformed in it a second slot through which the front needle 4 passes. This second slot is in front of and parallel to the usual slot through which the rear needle 2 passes.
  • the awl segment has fixed in it directly in front of the usual awl l2, a second awl M.
  • the looper 6 is operated to lay the needle threads in the hooks of the needles by mechanism similar to that shown in the aforementioned patent to French and Meyer.
  • the machine provided with a device 28 spaced from the work support for bedding the upper into the angle or crease between the sole margin and the last (and if desired supplying a rand strip there) substantially similar to and operated in the same manner as the de-- vice shown in the patent to Ricks No. 1,321,148 dated November 11, 1919.
  • the machine is also preferably provided with a sole straightening tool 22 such as is disclosed in said Ricks patent.
  • the machine when adapted for lasting and stitching sandals or veldtschoen as referred to, may be provided with means by which the upper may be intermittently pulled to its last and over the work support just before the awls enter the work and the feed takes place.
  • Such means may conveniently comprise a foot 24 ( Figure 4) having on its upper surface teeth which are adapted to engage the margin of the upper in the angle or crease formed between the sole margin and the last.
  • the foot engages the margin of the upper, in
  • the machine of the present invention between the right hand end or edge of the work support I0 and the left hand end or edge of the bedding member 20, hereinbefore referred to, and is moved first upwardly to engage the upper and press it against the sole margin into the angle or crease between the sole and last, then rearwardly to pull the upper frictionally over the sole margin snugly to the last, then downwardly away from the upper and finally forwardly.
  • the foot 24 is preferably formed on or fixed to the forward end of an upwardly and rearwardly extending lever 26.
  • the lever 26 about midway of its length and therefore above and behind the foot is pivoted to the upper end of a substantially vertical link 28 by a pivot 38 extending across the machine.
  • the vertical link 28 is pivoted at its lower end to the feed slide 32 of the machine on an eccentric portion of a horizontal adjustable pivot 34 extending across
  • the rear end of the lever 26 is connected by a downwardly and rearwardly extending link 36 to a rearwardly extending link 38.
  • the said downwardly and rearwardly extending link 36 is connected both to the rear ,end of the lever 26 and to the rearwardly extending link 38 by ball connections 48, 42.
  • the rearwardly extending link 38 is connected at its forward end to the vertical link 28 by a ball connection 44 and at its rear end is connected by a universal coupling 46 to the lower end of a substantially vertical cam member 48.
  • the cam member 48 at its upper end has formed in it a square opening 50 which surrounds a cam 52 on the cam shaft 54 of the machine.
  • the cam member 48 has pivoted to it, near its lower end but just above the universal connection 46 hereinbefore referred to, the forward end of a rearwardly extending rod 56.
  • the rod 56 near its rear end is reduced in diameter and is slidingly mounted in a sleeve 58 threaded through a block 59 which is pivoted at 68 to a member 6
  • the rod at its rear end has on it an adjustable nut 63 and between this nut and the rear end of the sleeve 58 the rod has on it a spring which holds a shoulder 65 on the rod against the front end of the sleeve 58.
  • the foot 24 may be adjusted forwardly or rearwardly and the sleeve may be locked in adjusted position by a nut 18 on the sleeve.
  • the cam member 48 is moved down by its cam, the rear end of the horizontal link 38 is moved down about its ball connection 44 to the vertical foot lever carrying link 28 and moves down the rear end of the foot lever 28.
  • the foot 24 at the front end of the lever 26 is moved upwardly into engagement with the margin of the upper and as it moves upwardly it also, owing to the position of its pivot, moves forwardly so that it enters well into the crease between the projecting sole margin and last.
  • This means comprises a bar 66 mounted on the feed slide 32 so as to be adjustable forwardly and rearwardly of the machine. The bar passes rearwardly across the left-hand side of slide 32 so as to be adjustable forwardly and rearwardly of the machine.
  • the bar passes rearwardly across the lefthand side of the vertical link 28 and has at its rear end a lateral extension 6! which passes behind the vertical link 28.
  • the front end of the bar has threaded into it a horizontal rearwardly extending adjusting screw 68 which is prevented from endwise movement by a plate 68 fixed to the feed slide 32 and entering a groove on the screw formed between the head of the screw and a flange on the screw.
  • the foot may be so operated that after it has been moved up into engagement with the upper and has pulled the upper to the last and over the work support, it may be given a forward movement either in its raised position or after it has been slightly lowered to tuck the upper into the angle or crease between the work support and bedding member.
  • Such a forward movement preferably occurs after the awl has assist its passage on to the top of the adjacent work support. After the forward movement or the foot, it may then be lowered in readiness to be again raised into engagement with the margin of the upper.
  • a machine for sewing together a sole and the outturned upper of a shoe on a last having, in combination, stitch forming devices, an upper pulling foot, and means for actuating the foot against the upper margin to press the upper into the crease between the sole and the last and then away from the last to pull the upper frictionally over the sole margin, and snugly against the last during each stitch forming cycle.
