Definitions

  • a presser foot for sewing slide fasteners into garments or the like is provided with a central partition dividing two parallel slots.
  • the partition has a tapered tip end located outwardly beyond a flat bottom surface of the sole portion of the foot and a sewing needle guide bore extending out through the tapered end.
  • This invention relates to improvements in a presser foot for a sewing machine, and has particular reference to a sewing machine foot for use in sewing a slide fastener to a garment or the like. More particularly, it is to a presser foot of the type that the invention is directed, which is suitable for sewing a concealed or hidden slide fastener having warp-knitted carrier tapes'.
  • presser feet have been heretofore devised and used to this end, but in all cases it is essential that such feet be constructed so as to provide a line of stitching as close as possible to a row of interlocking fastener elements in order to conceal the fastener completely within a joint in the fabric of the garment simulating a real sewn seam when the joint is closed by a slider of the fastener.
  • the invention provides a presser foot for sewing a concealed slide fastener into a garment or the like, the fastener having two rows of interlocking fastener elements carried on respective carrier tapes of a warp-knitted structure, said presser foot comprising a foot having a sole portion disposed for guiding engagement with the web portion of the carrier tape and a partition having an opening for receiving a sewing machine needle, said partition having its bottom end located outwardly beyond the level of said sole portion and disposed for guiding engagement with an interwale groove closest the coupling heads of the fastener elements.
  • FIG. 1 is a perspective view of a presser foot shown in reversed disposition and constructed in accordance with the invention
  • FIG. 2 is a front end elevation on enlarged scale of the presser foot of FIG. 1;
  • FIG. 3 is a cross sectional view illustrating the manner of stitching a concealed slide fastener to a garment fabric
  • FIG. 4 is a perspective view of a modification in reversed disposition according to the invention.
  • FIG. 5 is a cross sectional view of the same shown in operative condition.
  • FIGS. 1 and 2 there is shown a presser foot generally designated at 10 which is constructed in accordance with the teachings of this invention, and which comprises a foot position 11 and a shank 12 extending upwardly from the heel 13 of the foot 11.
  • the shank 12 is adapted to connect the presser foot 10 to a presser bar of a sewing machine not shown.
  • the foot 11 is provided with a pair of laterally spaced slots 14 and 15 each of which serves as a guideway for one of the two rows of interlocking fastener elements E on respective carrier tape T and extends the full length of the foot portion 11.
  • the slots 14 and 15 are slightly flared in opposite directions from a vertical plane through the longitudinal center axis of the foot portion 11, with the inner side walls 16 and 17 of the respective slots converging towards the bottom of the foot to form a downwardly tapered partition or ridge 18.
  • a needle guide bore 19 extends vertically through the longitudinal center line of the foot 11, i.e. centrally through the partition 18 and is adapted to receive a sewing machine needle N as the latter makes a vertical sewing motion.
  • the slots 14 and 15 serve to receive the row of interlocking elements E and hold them erect therein during the up and down movements of the sewing needle N as shown in FIG. 3.
  • the foot 11 is provided with separate side sole portions 20, 21 having flat bottom surfaces 20a, 21a, respectively which serve to guide and flat hold the web portion of the carrier tape T during the progressive sewing operation.
  • the partition 18 functions to prevent interference of the fastener elements E with the needle N during the sewing operation.
  • the partition 18 has its bottom tip end 18a located below or outwardly beyond the level of the flat bottom surfaces 200, 21a of the sole portions 20, 21.
  • the distance of projection of the tip end 18a of the partition l8 beyond the level of the bottom surfaces 20a, 21a of the sole portions 20, 21 corresponds substantially to the depth of an interwale groove G of the carrier tape T, and the width of the tip end 18a is substantially equal to the width of the interwale groove G.
  • the protruded tip end 18a of the partition 18 functions to hold the said interwale groove G perfectly in alignment with the axis of vertical movement of the sewing needle N and keep the groove G clear for the passage of the needle N so that the latter can provide a sewn seam properly in and along the groove G of the tape T.
  • FIGS. 4 and 5 There is shown a modification in FIGS. 4 and 5 which is characterized by the provision of a semicircular needle receiving recess 22 in each of opposite side partitions 23 and 24 which projects beyond the level of tape guide surface 25 and which is dimensioned to fit into the groove G for purposes already stated in connection with the function of the partition 18. lmportantly, the position of the partition 23, (24) registers with the vertical path of the sewing needle N, as seen, so that the needle N can pass through and along the particular groove G closest to the coupling heads Ea of the elements E while the said groove G is held spread open by the partition 23, (24).
