Definitions

  • An elongated cylindrical rod is supported on an upper Oct. 22, 1965, Pat. No. 3,3 9,736, w c s a portion of a presser foot component.
  • the rod extends tinuation-in-pafl of 4751436, 28, 1965, through a transverse bore in a connector block.
  • the 3342'15L connector block includes one component of a joint between it and a mounting shank.
  • the mounting shank is adapted for connection to the presser bar of a sewing machine.
  • the present invention relates to presser foot assemblies for sewing machines, and more particularly to such assemblies for use in installing zippers or other types of elongated articles which need guiding during their installation, e.g. cording, piping, etc. Some of the features of the invention specifically relate to presser foot assemblies for use in installing invisible or con-' cealed zippers.
  • Known laterally adjustable presser foot assemblies are of two types.
  • the adjustable connection comprises a member'having a laterally elongated slot which receives the shank portion of the clamp screw. Examples of foot assemblies of this type are shown by Burgess, U.S. Pat. No. 3,024,751 and Micale, U.S. Pat. No. 3,294,048.
  • the second type includes a slide joint having only two positions of use. The slidable member is retained in each of these positions by the pressure of a spring biased ball detent. This type of foot assembly is shown by I Yoshida, U.S. Pat. No. 3,098,460.
  • Other known forms of presser feet are disclosed in Smallbone, U.S. Pat. No. 1,930,628, and in Dixon et al., U.S. Pat. No. 2,909,136.
  • the invention relates to improved ways of adjusting a foot component relative to its mounting shank, and to mounting meanspermitting the foot component to pitch in response to the passage of materials of unequal thickness below it.
  • FIG. 1 is a pictorial view of a form of presser foot attachment according to the invention, including a showing of two substitute mounting shanks for use in connecting the foot assembly to other types of sewing machines;
  • FIG. 2 is a side elevational view of the foot component of FIG. 1, with an intermediate part of the foot component shown in longitudinal section;
  • FIG. 3 is a top plan view of the zipper footassembly of FIGS. 1 and 2;
  • FIG. 4 is a fragmentary side elevational view of the high bar mounting shank secured to the mounting block.
  • the zipper foot assembly is shown to comprise a mounting shank 10 and a foot component 12.
  • Foot component 12 includes a pair of bottom runners 14 which extend in parallelism on opposite sides of the zipper chain path through the foot component 12. Between the runners 14 the zipper chain path exists as a longitudinal bottom groove 16.
  • Such groove 16 is-of such a height and width that its bounding surfaces neither contact nor interfere with the zipper tooth chain.
  • roller 20 includes live axles 22 at its opposite ends. These axles 22 are snap fitted into downwardly opening bearing sockets 24 (FIG. 2) formed in the forward end portions of the side walls 26, 28of the foot component 12. These bearing sockets 24 have main portions which are slightly larger in diameter than the axles 22 and entrance portions which are narrower than the diameter of the axles 22. As a result, the axles 22 have to be snap fitted into the sockets 24.
  • This construction both makes it easier to construct and fabricate the foot assembly, and makes it possible for the user to readily replace the roller 20 with a different type of roller, e.g. a roller for installing a different type of zipper.
  • Roller 20 includes a M-shaped peripheral groove providing two guide avenues 30, 32 on opposite sides of a divider 34. Such roller 20 is designed to be used for installing a flat tooth metal or a continuous filament plastic zipper.
  • Roller 20 also includes presser surfaces'36, 38 on the opposite sides of the guide means 30, 32, 34.
  • Roller 20 is mounted for free rotation about an axis which is substantially transversely related to the sewing path.
  • Each guide grooves 30, 32 allows free passage of its zipper tooth chain through the foot component 12. Grooves 30, 32 also correctly orient the zipper tooth chains relative to the needle.
  • the entrance avenues 30, 32 of the foot component 18. are configured to roll the zipper teeth contacted by the side surfaces thereof over into a nearly supine position, with the inner side portions of the teeth closely adjacent the fabric to which the zipper tape is being sewn. Placement of the teeth in a nearly supine position requires a rolling of the teeth from their natural attitude into the nearly supine position. It is desirable to establish a stitch line which is quite close to the portions of the teeth bounding the needle. Thus, this criteria is used for designing the entrance portions 30, 32 of the zipper teeth avenues.
  • the foot component 12 includes a top panel 40.
  • Top panel 40 includes a pair of oppositely projecting extensions 42, 44 having upturned end portions 46, 48 which are parallel to each other.
  • the ears 46, 48 include recesses for receiving reduced diameter end portions of a smooth support rod 50 shown to be snap fitted into the recesses.
  • a connector block 52 is mounted on the rod 50 for longitudinal travel therealong and lateral travel relative to the body.
  • Connector block 52 includes a transverse bore through which the rod 50 extends.
  • Block 52 is formed to include a joint component, illustrated in the form of a laterally directed T-shaped tension 66.
  • the mounting shank 54 is provided with a pair of selectively usable, complementary mortises 68, 70; mounting shank includes a single complementary mortise 72 and shank 56 also includes a single complementary mortise 74.
  • the bottom surface of block 52 is spaced above the top panel 40 of body 12.
  • the bottom surface of mounting shank 10 is also spaced above top panel 40. This arrangement permits a limited amount of pivotal movement of the rod 50 within its supports upon pitching movement of the foot component 12, caused by changes in the thickness of material below the foot component 12.
  • the high bar mounting shank 54 is constructed so that it can be turned end-for-end and be used for mounting the foot component 12 onto a slanted presser bar of a slant needle type sewing machine.
  • Mounting shank 10 is a low bar type mounting shank and mounting shank 56 is an end screw type mounting shank.
  • the mounting shank 54 is provided with clamp screw receiving slots 58, 60 at its opposite ends; shank 10 is provided with a single mounting screw receiving slot 62; and shank 56 includes a single mounting screw receiving slot 64.
  • Mounting shank 10 is to be used with the low bar type presser bar, such as shown by FIG. 7 of my U.S. Pat. No. 3,342,5l5.
  • Shank 56 is to be used with the end screw type presser bar, such as shown in FIG. 9 ofmy US. Pat. No. 3,342,151.
  • the mounting block 52 frictionally grips the rod 50, but relative axial and pivotal movement can still occur between the rod 50 and its end supports in response to forces which exceed the frictional forces.
  • a presser foot assembly comprismg:
  • a foot component including downwardly directed presser surface means
  • transverse rod member mounted atop said foot component, said rod member being relatively' smooth surfaced and substantially circular in cross sectiomand mounting means removably connectible to said presser bar, and said mounting means frictionally gripping said transverse rod member but permitting longitudinal gripping said transverse rod member but permitting longitudinal sliding movement of the rod member and said foot component relative to said mounting means, to provide for lateral adjustment of the foot component relative to the mounting means and the presser bar, and said transverse rod member mounting said foot component for limited pivotal movement within a vertical plane, so that the foot component is free to pitch slightly in response to variations in material thickness below it.
  • said mounting means includes a connector block which frictionally grips said transverse rod member, mounting shank means, means for removably connecting said mounting shank means to said connector block, and means for removably connecting said mounting shank means to said presser bar.
  • each ear includes an upwardly open recess having an entrance portion narrower than the diameter of the rod member at such recess, and the rod member is snap fitted into said recess.
  • each ear includes an upwardly open recess having an entrance portion narrower than the diameter of the rod member at such recess, and the rod member is snap fitted into said recess.
