Abstract
Abstract An elongated cylindrical rod is supported on an upper portion of a presser foot component. The rod extends through a transverse bore in a connector block. The 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
154 words
For use with a sewing machine equipped with a presser bar, a reciprocating needle and a material advancing mechanism, a presser foot assembly comprising: a foot component including downwardly directed presser surface means; a transverse rod member mounted atop said foot component, said rod member being relatively smooth surfaced and substantially circular in cross section; and 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.
Claim 2
Dependent Claim
154 words
For use with a sewing machine equipped with a presser bar, a reciprocating needle and a material advancing mechanism, a presser foot assembly comprising: a foot component including downwardly directed presser surface means; a transverse rod member mounted atop said foot component, said rod member being relatively smooth surfaced and substantially circular in cross section; and 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.
Claim 3
Dependent Claim
154 words
For use with a sewing machine equipped with a presser bar, a reciprocating needle and a material advancing mechanism, a presser foot assembly comprising: a foot component including downwardly directed presser surface means; a transverse rod member mounted atop said foot component, said rod member being relatively smooth surfaced and substantially circular in cross section; and 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.
Claim 4
Dependent Claim
154 words
For use with a sewing machine equipped with a presser bar, a reciprocating needle and a material advancing mechanism, a presser foot assembly comprising: a foot component including downwardly directed presser surface means; a transverse rod member mounted atop said foot component, said rod member being relatively smooth surfaced and substantially circular in cross section; and 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.
Claim 5
Dependent Claim
50 words
A presser foot assembly according to claim 1, wherein said foot component includes means forming a guide avenue for an invisible zipper chain shaped to roll said invisible zipper chain from its normal attitude offset upwardly from its mounting tape into an outwardly leaning attitude in region of the needle.
Claim 6
Dependent Claim
51 words
A presser foot assembly according to claim 1, herein 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.
Claim 7
Dependent Claim
72 words
A presser foot assembly according to claim 3, wherein said connector block comprises one component of a two component joint between it and the mounting shank means, and said mounting shank means comprises a plurality of different, selectively usable mounting shank members, each having an identical joint component constituting the second component of said joint, and each said mounting shank member being adapted for connection to a different type of presser bar.
Claim 8
Dependent Claim
42 words
A presser foot assembly according to claim 1, wherein said foot component includes a pair of opposite side extensions, each including an upwardly extending ear at the outer end thereof, with said ears serving as end supports for the transverse rod member.
Claim 9
Dependent Claim
19 words
A presser foot assembly according to claim 5, wherein said transverse rod member is rotatably supported by said ears.
Claim 10
Dependent Claim
41 words
A presser foot assembly according to claim 6, wherein 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.
Claim 11
Dependent Claim
42 words
A presser foot assembly according to claim 3, wherein said foot component includes a pair of opposite side extensions, each including an upwardly extending ear at the outer end thereof, with said ears serving as end supports for the transverse rod member.
Claim 12
Dependent Claim
19 words
A presser foot assembly according to claim 8, wherein said transverse rod member is rotatably supported by said ears.
