Definitions

  • FIG. 7 shows a diagram of movements
  • FIG. 1 an automatic pattern-stitch sewing machine is shown in simplified form in which, for the sake of clarity, the actual stitching device with the rows of needles that move up and down etc. has been omitted.
  • the automatic machine has a frame A on the right-hand side of which a drive housing B with the new drive assembly is mounted; the drive assembly is driven by the motor C.
  • a material guide E slides within trestle arms D.
  • the material-guide has mounted on it a material feed roller F and a roller G onto which the material web is rolled after having been pattern-stitched. It also bears the material-feed rollers H and the materialfeed-advance rollers J.
  • On the frame is located a needle bed K with two rows or arrays of needles N and N the needle bed K also carries the main drive shaft L, which drives the actual stitching device (not shown).
  • FIGURE 2 shows the drive assembly with the continuously driven main drive shaft L, the shaft X with stage by stage drive for the feed advance of the material guide and the push rod V which is moved back and forth step for step by the pattern disc U.
  • the step by step movement it is provided by a stepped switching mechanism.
  • This comprises a cam disc 1 rigid with the shaft L and moving a push rod 3 by means of a cam-follower roller 2.
  • FIGS. 4a-c and 5ac the effect exerted by the corrections or adjustments on the feed-advance length d relative to the pattern cycle can be explained.
  • the automatic machine is operating with two rows of needles Where however the needles are offset from one another.
  • the interval or spacing (in the direction of material feed) between the rows of needles is n and the feed-advance length is d.
  • FIGURES 6 to 8 refer to the stitching of a rectangular checked pattern. This will be stitched with a single row of needles, as shown in FIG. 6, so that errors on the feed-advance length are less obvious. On the other hand, the difficulty now arises that the web of material has alternately to be advanced only or moved laterally only.
  • the shaft 16 makes two revolutions during the period in which the vertical shaft 12, which bears the pattern disc, completes a single revolution. It is obvious that in place of the drive shown with only three stages one with more than three stages can be utilized. The switching can also be carried out in another manner, for example in the manner of a Norton transmission or by means of a draw wedge.
  • the drive housing B is preferably filled with oil so that the drive is at all times lubricated.
  • the pattern disc U is located above the cover of the housing beneath the hood R in air and is therefore easy to change.
  • the shafts for the operating controls Y and Z (shaft 33) are ducted through the housing wall to the exterior through an oil-seal.
  • a pattern-stitch sewing machine having a needle bed, a fabric guide shiftable relative to said needle bed in a fabric-advance direction, fabric-engaging rollers on said guide and adapted to displace the fabric therealong, and a pattern disk for controlling the cyclical displacement of said guide, the improvement which comprises:
  • a drive assembly including a main drive shaft
  • a stepping mechanism operable by said main drive shaft for incrementally displacing said pattern disk to shift said guide;
  • said stepped transmission means including a further shaft provided with a gear meshing with said gear means, an output shaft operatively connected with said rollers, a first set of toothed wheels on said further shaft, and a second set of toothed wheels rotatably entraining said output shaft and mounted thereon with freedom of axial displacement of at least one of the toothed wheels of said second set whereby such axial displacement shifts said transmission means between said ratios;
  • said means for shifting said transmission means including a shifting fork engaging the axially shiftable toothed wheel for selectively displacing same along said output shaft.
