Definitions

  • a control lever arrangement for regulating the stitches in sewing machines for zigzag stitching comprising a lever for controlling the transverse position of the needle bar and a lever for regulating the width of stitch in relation to said transverse position, comprises a plate adapted to be applied to the lower vertical portion of the free arm of a sewing machine, the said plate having two slots therein in which the said levers are arranged to be displaceable.
  • This plate may be the same plate which is known manner carries the control lever for interrupting or re-introducing the lifting movement of the material feed when such device is provided on the machine.
  • FIG. 1 is a diagrammatical perspective view of the free arm of a sewing machine for zigzag stitching, wherein the levers for controlling and regulating the stitch are disposed in accordance with the invention.
  • Fig. 2 is a fragmentary view showing in cross-section the plate carrying the levers.
  • the lever 1 which is connected with appropriate parts within the free arm of the machine, which arm is of the conventional kind, brings about a displacement of the needle bar in such a way that a sewing action can be carried out either to the right or along the center or to the left, according to the fact as to whether this lever, which s preferably resilient, is caused to engage in one or the other of three notches 2 formed in the slot 3 of the plate 4.
  • the lever 5 also through the medium of suitable elements disposed within the free arm, regulates the width of the zigzag stitching, such width being proportional to the displacement of the lever 5.
  • the grip 6 of the lever 5 can be screwed tight in such a way that its surface 7 can be caused to bear against the suitably shaped surface 8 of the plate 4 in a position which is dependent on the screwing action.
  • the lever 9 serves to control the release of the material feed from the element which moves the same vertically, or to connect it with said element.
  • This lever which is preferably resilient, can be moved into and held in the one of two notches 10 provided n the slot 11, according to whether the release or connection is to be elected.
  • the plate 4 is located below the lever 12, which regulates the length of stitch. As regards its application to the free arm, this plate is introduced into an opening in the arm, and it bears by means of a recessed edge against said arm, to which it is secured by connecting means situated inside the arm and invisible from the exterior (Fig. 2).
  • a sewing machine for zigzag stitching having a free arm provided with a vertical member and a horizontal member, a reciprocating and transversely oscillating needle bar carried by the free arm, a shiftable feed mechanism, a lever for shifting said feed mechanism into and out of feeding position, a lever for controlling the transverse position of the needle bar and a lever for regulating the width of stitch in relation to said transverse position, the vertical member of said free arm having an opening in the lower front portion thereof, a control plate mounted on the lower front portion of the vertical member of the free arm and closing said opening, said control plate hav ing three slots therein in close proximity, actuating means carried by the first mentioned lever and extending through one of said slots, actuating means carried by the second mentioned lever and extending through another of said slots, and actuating means carried by the third mentioned lever and extending through the remaining slot, said plate closing said opening having an outwardly extending peripheral flange in the plane of the front face thereof to engage the front surface of the vertical member and limit inward movement of the plate
