Definitions

  • a still further object of the invention is to provide an improved means for adjustably mounting stitch fingers so that tight or loose seams can be produced at will and also so that the tightness or looseness of the seam can be varied While the sewing operation is in progress of being performed.
  • FIG. 1 is a fragmentary horizontal sectional viewof a cup-feed sewing machine, similar to the sewing machine shown in United States Patent No. 2,334,672, and embodying the present invention,
  • the sewing machine As the sewing machine operates, it forms stitches around the two blades 29 and 39 and through the marginal edges of the material plies, thereby'joining the edges 48 and 49 of the two pieces of material.
  • theouter feed-cup 23 is mounted in such a manner as to move toward or away from the feed-cup 22 and, thus when the material between the two cups 22 and 23 is relatively thin, the two cups 22 and 23, as shown in FIG. 2, will be closely adjacent to one another and thiscauses the blade 39 to move closely adjacent to the blade 29. Under this circumstance, tight stitches are produced by the blades 29 and 39.
  • a second stitch-finger supported from said movable supporting means, at least a portion of said 'second'stitchfinger being placed in adjacent structural relationship to a portion of said first stitch-finger so as to permit said stitch forming devices to form stitches around the outside of both portions of said stitch-fingers taken as a pair.
  • a sewing machine adapted to sew material and having in combination stitch forming devices, a fixed supporting means, a first stitch-finger supported from said fixed supporting means, and adapted to engage the material sewed on one side thereof, movable supporting means movable with respect to said fixed supporting means, and a second stitch-finger supported from said movable supporting means and adapted to engage the material sewed on the other side thereof, at least a portion of said second stitch-finger being placed in adjacent structural relationship to a portion of said first stitchfinger so as to permit said stitch forming devices to form stitches around the outside of both portions of said stitchfingers taken as a pair.
