Definitions

  • Fig. 2 is a plan view illustrating on an enlarged scale the stroke control member
  • Fig. 5 is a decorative bead seam
  • reference numeral 1 designates the hol- States Patent O low standard of a zig-zag sewing machine
  • numeral 2 the handle knob of the lever 3 serving to adjust the stitch length, i.e. the fabric feed.
  • Lever 3 may be raised and lowered within the limits of a Vertical slot or guide way 4 in standard l, and is connected with the mechanism of the stitch length adjusting device (not shown).
  • a stroke control member 6 is pivotally mounted on the bolt portion of a screw 5, secured to the wall of standard 1 to one side of and below slot 4. Said member is formed at its end opposite the pivotal axis with a projection in the form of an abutment or a hook 6a.
  • the member 6 is mounted eccentrically with respect to the bolt, so that fine adjustment is aided.
  • the member 6 carries a handle knob 8 secured thereto by means of interengageable formations constituted by a pin 7 carried by said knob 3 and a recess 9 of the standard 1, whereby said pin may engage recess 9.
  • Reference numeral it designates a movable scale rotatably connected in a manner (not show) with the stitch [length adjusting 'lever 3.
  • the described arrangement operates as follows: It mayl be assumed that the stitch length resulting from the position of the stitch length adjusting lever 3 indicated by A in Figs. 2 and 3 should be changed in order to sew a bead seam 11 bordering a button hole (Fig. 6).
  • the control member 6 is brought into an intermediate operative position by swinging it into the position indicated by dot-and-dash lines in Fig. 2.
  • the stitch length adjusting lever 3 may be moved upwardly only as far as the point at which it bears against the hook 6a of abutment member 6.
  • This adjustment of lever 3 may be effected without looking at it, as its stroke is limited by the hook portion 6a of the abutment member 6.
  • the adjusting movement of the stitch length adjustment lever 3 may be made from any starting position and at any time.
  • Fig. 4 shows a zig-zag seam in which the portions designated by 12 are sewn with the member 6 in inoperative position while the portions 13 are sewn as bead seams with the member 6 in the operative position shown by dot-and-dash lines in Fig. 2.
  • Fig. 5 shows a zig-zag bead seam 14 of varying stitch width.
  • the zig-zag sewing machine has a standard which encloses said mechanism, which comprises a stitch length adjustment lever, a stroke control member located for pivotal movement on said standard, projecting means on said member, and a guideway a'long which said adjustment member may be moved and which terminates in two extreme stops against which said adjustment lever may abut when moved along said guideway, the projecting means of said control member being arranged and constructed to move in crosswise direction to said guideway and to thereby determine an intermediate stop position when said control member is moved to a location onto said guideway to thereby form a temporary stop for said stitch length adjustment lever ⁇
  • the control lever is arranged for pivotal movement on said standard and about an axis which extends perpendicular to the direction of said guideway, the control member being further provided with a knob facilitating movement of said control member, and respective interengage
  • a sewing machine having means for adjusting the stitch length and the fabric feed to thereby border button holes and produce decorative and like stitches, respectively; comprising a stitch length adjustment lever, a pivotally .supported stroke control member, projecting means on said member, and a guideway along which said adjustment lever may move to two extreme operative positions and to an intermediate operative position, respectively, said control member being swingable about its pivot onto said guideway, so that said projecting means eX- tends across the latter and determines said intermediate position of said adjustment lever.
  • a sewing machine having means for adjusting the stitch length and the fabric feed to thereby border button holes and produce decorative and like stitches, respectively; comprising a stitch length adjustment lever, a stroke control member, and a guideway along which said adjustment lever may move to two extreme operative positions and to an intermediate operative position, respectively, said control member including an abutment adapted to be moved in crosswise direction to the median part of said guideway, whereby upon movement of said control member with said abutment to said median part of said guideway said intermediate position will be determined, thereby forming a temporary stop by said abutment for said stitch length adjustment lever on its movement along said guideway.
  • said adjusting means comprising a stitch length adjustment lever, a stroke control member located for pivotal movement on said standard, projecting means on said member, and a guideway along which said adjustment lever may be moved to two extreme operative positions and to an intermediate operative position, respectively, said projecting means determining said intermediate position upon swinging of said control member about its pivot so that said projecting 5 means is disposed in the path of said guideway at a predetermined location thereof and forms an abutment lengthwise of said guideway for said adjustment lever, the axis about which said pivotal movement of said control member occurs extending perpendicular to the direction of said guideway.
  • control member being provided with a knob facilitating movement of said control member, and respective interengageab'le formations on said knob and on said standard to retain said control member in two end positions relative to said guideway.
  • said adjusting means comprising a stitch length adjustment lever projecting from within said standard therewithout, a stroke control member located and substantially flat on said standard, and an elongated guideway terminating in two extreme stops against which said adjustment lever may abut, when moved along said guideway, said control member being pivotally supported at one end to move with its other end, which is hook-shaped in crosswise direction of said guideway thereby determining an intermediate position in which said control member is moved to a temporary stop in said guideway, so that said stitch length adjustment tlever is impeded in its movement along said guideway.
