Definitions

  • Such presser feet are particularly useful for carrying out sewing of considerable thickness, such as binding stitching, for example.
  • the presser foot according to the invention is characterized in that this retractable portion is suspended at the pivoting axle, stop means limiting its oscillation, the spiral spring being engaged in a housing arranged in this retractable portion and supported against the axle.
  • FIG. 1 shows a plan view, from below, of said embodiment
  • FIG. 2 shows a vertical section along the line II-II of FIG. 1.
  • the presser foot illustrated comprises a sole plate 1 pivoted by an axle 2 on a support 3 intended to be fixed against the presser bar of a sewing machine, by meansof its fixing yoke 4.
  • the sole plate 1 of this presser foot has in the usual manner a passage 5 for the needle as well as a slot 6 enabling the introduction of the thread on preparing the sewing machine for sewing.
  • a portion of the sole plate 1, the portion disposed behind the needle passage hole 5, is upwardly retractable.
  • the sole plate 1 has an opening 7 of generally rectangular shape within which is engaged the retractable portion 8 in the form of a block.
  • This retractable portion 8 is suspended from the pivoting axle 2 by means of two lugs 9 which extend upwardly from the lower face of this portion 8.
  • a housing 10 which extension is terminated by the two lugs 9 and which has in its central portion a housing 10.
  • this housing 10 is arranged a spiral spring 11 resting by one of its ends on the bottom of the housing 10 and supported by its other end against the pivoting axle 2.
  • This spring 11 therefore tends to hold the retractable portion 8 at the level of the lower face of the sole plate 1.
  • the openings 12 arranged in the lugs 9 for the passage of the axle 2 are of elongated shape so as to enable upward displacement of the retractable portion 8, against the action of the spring 1 1.
  • a rod 13 is fixed transversally in the sole plate 1 between the needle passage hole 5 and the retractable portion 8. This rod 13 serves as a stop for the retractable portion 8 to limit its oscillating movement around the axle 2. It should be noted that one edge 14 of the sole plate 1 also constitutes a stop opposite the rod 13. These stops 13 and 14, as well as the elongated openings 12 arranged in the lugs 9, ensure guidance of the retractable portion 8 during its displacements in the vertical direction.
  • this rod 13 is also useful for the guidance of the thread thereby enabling wear of the rear edge of the passage 5 provided in the sole plate 1 to be avoided, which sole plate 1 is preferably made of synthetic material such as the material known as lasn'cs .for exarr le. p It will be unotwithstandingood without elaborating further from the view of FIG. 2 especially, that on executing a sewing stitch of considerable thickness, such as binding stitch, the portion 8 is driven back upwardly against the action of the spring 11 by the sewing in proportion to the execution of the latter by the needle. This upward displacement of the retractable portion 8, hence enables the principal portion of the lower face of the sole plate 1 to maintain contact with the parts to be sewn and to ensure holding the latter against the needle hole plate and against the feed dog device respectively.
  • the retractable portion 8 is also made of a synthetic material, that is to say of so-called plastics material, of the same nature as that forming the sole plate 1.
  • Presser foot for a sewing machine comprising a support adapted to be attached to the presser bar of the machine, a sole plate pivoted by an axle to said support and defining a needle passage hole, a portion of the sole plate situated behind the needle passage hole being mounted to retract upwardly against the action of a spiral spring, said retractable portion suspended from said pivoting axle in such a way that, when the presser foot is in its inactive position, the bottom face of said retractable portion of the sole plate remains flush with the bottom face of the surrounding parts of the bottom face of the sole plate, stop means limiting the oscillation of said retractable portion, said spiral spring engaged in a housing within said retractable portion and supported against said axle.
  • stop means comprise, on one hand, a rod fixed transversally in the sole plate between the needle passage hole and the retractable portion and, on the other hand, one edge of the sole plate.
  • the retractable portion has at least one elongated opening through which it is suspended from said pivoting axle, said elongated opening cooperating with the stop means to ensure guidance of the retractable portion in the vertical direction.
  • the retractable portion has at least one elongated opening through which it is suspended from said pivoting axle, said elongated opening cooperating with the stop means to ensure guidance of the retractable portion in the vertical direction.
