  • Known assemblies of the above kind comprise at least one graduated rule extending forwardly or rearwardly of the presser foot and in the same plane.
  • a principal object of the present invention is to provide a presser foot assembly comprising at least one graduated rule, particularly for measuring the length of a seam from a needle passage opening of said presser foot, said graduated rule extending forwardly or rearwardly of a sole portion of said presser foot and in the same plane, a plate means comprising said graduated rule and hinge means for hingedly securing said plate means to said sole portion of said presser foot, the hinge axis of said hinge means extending in a direction transverse to said sole portion of said presser foot.
  • Another object of the invention is to provide a presser foot assembly having hinge means comprising arms integral with said plate means, at least one of said arms being resiliently displaceable in the plane of said plate means, each one of said arms including on its surface opposite to the other arm a projection or recess engaged respectively in a recess or on a projection disposed on each one of the opposite lateral surfaces of a sole portion of the presser foot in a location near to one of the ends of said sole portion.
  • a further object of the invention is to provide a presser foot assembly having plate means made of a material which is at least translucent.
  • a still further object of the invention is to provide a presser foot assembly having plate means made of synthetic material and hinge means comprising arms forming integral portions of said plate means.
  • Still another object of the invention is to provide presser foot assembly having arms provided on both sides of a notch formed in one of the ends of a plate means, at least one slot forming an extension of said notch along at least one of said arms for conferring to said arm a resiliency required for its resilient displacement in the plane of said plate means.
  • FIG. 1 is a side view, on an enlarged scale, of a presser foot assembly forming an embodiment of the invention
  • FIG. 2 is a top view on an enlarged scale of the assembly of FIG. 1;
  • FIG. 3 is a fragmentary side view, similar to FIG. 1, illustrating the graduated rule and a sole portion of the presser foot of the assembly of the FIGS. 1 and 2;
  • FIG. 4 is a top view, similar to FIG. 2, of a presser foot assembly forming another embodiment of the invention.
  • a presser foot forming a part of a first embodiment of the invention illustrated in FIGS. 1-3, comprises a sole portion 4 hingedly secured by means of a pin 5 to a support member 6 provided with a stirrup 7 for the mounting of the presser foot on the presser rod of a sewing machine.
  • the sole portion 4 of the presser foot has a conventional. needle passage opening 8 for the sewing needle of the sewing machine and a slot 9 for allowing the introduction of the upper thread in the opening 8 when preparing the machine for a sewing operation.
  • a graduated rule forming a part of the first embodiment of the invention shown in FIGS. 1 3, consists of a plate 10 made of transparent synthetic material.
  • the plate 10 is provided with a notch 11, having a width corresponding to the width of the sole portion 4 of the presser foot at its rear end.
  • the lateral edges of the notch 11 form two arms 12, 13 having nipples or projections 14 projecting from their opposite lateral surfaces and disposed for snap-in engagement with recesses 15 provided on each one of the lateral surfaces of the sole portion 4 of the presser foot in a location near to the rear end of the presser foot.
  • the notch 11 continues along the arm 13 of the plate 10 in form of a slot 16 for conferring to the arm 13 in the plane of the plate 10 the elasticity required for allowing a spreading of the arms 12 and 13 when mounting and dismounting the plate 10 on and from the sole portion 4 of the presser foot, respectively.
  • Both sides of the rear end of the sole portion 4 of the presser foot are provided with a ramp 17a and 17b respectively for guiding the nipples 14 of the arms 12 and 13 of the plate 10 in the direction of the recesses 15 of said lateral surfaces of the sole portion 4 of the presser foot (FIG. 3).
  • ramps 17c cause a progressive spreading of the arms 12, 13 of the plate 10 up to the moment of the engagement of the nipples l4 of the arms 12, 13 in the recesses 15 of the sole portion 4, when the plate is being mounted on the sole portion 4.
  • the plate 10 is provided with a graduation or scale beginning at the center of the needle passage opening 8 of the sole portion 4 of the presser foot.
  • This graduation is set up in a manner such that the position of the recesses in the lateral surfaces of the sole portion 4 as well as the position of the nipples 14 on the opposite surfaces of the arms 12 and 13 of the plate 10 are taken into account.
  • the mounting of the plate 10 on the sole portion 4 of the presser foot of the sewing machine can be achieved by a simple displacement of the plate 10 in the direction from the right to the left side of the FIG. 3 on the needle hole plate of the sewing machine, when the sole portion 4 of the presser foot is in its lowered position on said needle hole plate.
  • the plate 10 is mounted for pivotal movement in the recesses 15 of the sole portion 4 of the presser foot.
  • the plate 10 is allowed to be lifted by a reinforced seam at the time of the passage of this seam, even though the presser foot remains in contact with the cloth to be sewn.
  • Plate 10 may be easily separated from the sole portion 4 by spreading the arms 12 and 13.
  • the sole portion 4 of the presser foot is made of transparent synthetic material like the plate 10.
  • the sole portion 4 and the plate 10 could, however, be made of translucent or opaque material, e.g., of metallic material. In this latter case, it may be desirable to provide the plate 10 with a longitudinal median slot leaving the area where the seam passes uncovered. Thus, measuring of the length of the seam in the course of the sewing operation is made possible.
  • the plate 10 is enlarged in the direction of its free end, in order to facilitate the reading of the graduation provided on the plate 10.
  • the plate 10 may be mounted at the front end of the sole portion 4 of the presser foot, thus allowing the measuring of the length of a seam obtained in the course of a sewing operation in the rearward direction.
  • the arms 12, 13 could be made of separate pieces fastened to the plate 10.
  • any other mounting means could be provided, e.g., a pin engaged in a boring formed in the hinge axis of the arms 12, 13 on the sole portion 4 of the presser foot.
  • the arms 12 and 13 of the plate 10 could include the recesses 15 or be bored right through and the sole portion 4 could be provided on its lateral surfaces with the nipples 14.
  • An assembly comprising a presser foot including a sole portion, a detachable graduated rule for measuring the length of a seam from a needle passage opening in said presser foot, said graduated rule comprising plate means, hinge means pivotally connecting said plate means adjacent the rear edge of the sole portion of said presser foot, the axis of said hinge means extending in a direction transverse to said sole portion of said presser foot, said plate means being pivotable to a raised position against the bar of the presser foot for sewing operations where measuring is not required and pivotable to a lowered position in the same plane as the sole of said presser foot for measuring the length of a seam.
  • said hinge means comprise arms integral with said plate means, at least one of said arms being resiliently displaceable in the plane of said plate means, each one of said arms including on its surface opposite to the other arm a projection engaged respectively in a recess disposed on each one of the opposite lateral surfaces of said sole portion of the presser foot in a location near to one of the ends of said sole portion.
  • said plate means is made of synthetic material
  • said hinge means comprising arms forming integral portions of said plate means, at least one of said arms being resiliently displaceable in the plane of said plate means.
  • said hinge means comprises arms integral with said plate means, at least one of said arms being resiliently displaceable in the plane of said plate means, each one of said arms having a recess on its surface opposite to the other arm, a projection on each one of the opposite lateral surfaces of said sole portion of the presser foot in a location near to one of the ends of said sole portion and engaged in said related recess.
