BACKGROUND OF THE INVENTION Field of the invention 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.
Description of the prior art Known laterally adjustable presser foot assemblies are of two types. In the first type the adjustable connection comprises a member having a laterally elongated slot which receives the shank portion of a clamp screw. Examples of foot assemblies of this type are shown by Burgess 3,024,751 and Micale 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 Yoshida US. 3,098,460.
SUMMARY OF THE INVENTION My aforementioned US. Pat Nos. 3,342,151 and 3,346,- 736, and my aforementioned application Ser. No. 678,742, disclose presser foot assemblies comprising a laterally adjustable foot component and a plurality of selectively usable mounting shanks, each connectable to a different type of presser bar. In such assemblies a slide joint is formed between the lower end of the mounting shank and a heel portion of the foot component. In use the foot component is held in position by friction forces existing at the slide joint. Lateral adjustment is effected by the user applying a sideways force on the foot component of sufficient magnitude to overcome the friction forces.
Presser foot assemblies of the present invention also comprise a laterally adjustable foot component and a plurality of selectively usable mounting shanks. The foot component is characterized primarily by a transverse rodlike member which extends through a transverse bore formed in a connector block. The connector block includes one component of a two component joint. The mounting shanks include identical joint components which are the second component of said joint. In use the proper mounting shank is selected and is joined to the connector block. The mounting shank is secured to the presser bar of the sewing machine. The foot component is moved laterally relative to the connector block to place it in proper position relative to the needle.
In preferred form the transverse member is a rotatable adjustment screw and the bore in the connector block includes internal threads which mate with the external threads on the adjustment screw. Adjustment is easily and accurately effected by the user merely rotating the screw to cause its lateral travel through the connector block, attended by sideways movement of the foot component.
Other aspects of the invention relate to specific characteristic features and/or constructional details of the mounting shanks and the foot component. These more specific features are hereinafter described in detail in the section of this document entitled Description of the Preferred Embodiments.

FIG. 7 is a fragmentary pictorial view of the front portion of a modified form of foot component, characterized by the front roller being removable and replaceable by a differently configured roller for performing a different sewing operation.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring specifically to FIG. 2, a reciprocating needle bar 10 (in reference) is shown spaced forwardly of a presser bar 12 of the upright high bar type. Bar 12 is equipped with a side clamp type of presser foot mounting mechanism, and when bar 12 is in its operative position such mounting mechanism is spaced relatively high above the needle plate (not shown).
The mounting mechanism comprises a flat side surface formed on the lower end portion of bar 12, a threaded aperture entering into the side of said lower portion, substantially perpendicularly to both said fiat side surface and the sewing path, and a clamp screw 14. The flat side surface on bar 12 is parallel to the sewing path. The clamp screw 14 has a large head having a flat inner surface which is parallel to such flat side surface. Clamp screw 14 also includes a threaded shank that is threadable into and out from the aperture in the lower end portion of bar 12.
In FIG. 2 a zipper foot assembly constructed according to the present invention is shown mounted in an operative position by the presser bar 12. Such assembly consists of two interlocking parts: a foot component 16 and a high bar mounting shank 18. The high bar mounting shang 18 is shown to be of channel form and to comprise a pair of spaced apart flanges 20, 22 and a web 24 interconnected between corresponding edges of the flanges 20, 22. The end portions of web 24 are formed to each include an outwardly opening blind slot 26, 28. These slots are colinearly related. Identical joint components, shown in the form of vertically oriented slideways 30, 32 are formed in diagonally opposed corners of the mounting shank 18.
As best shown by FIG. 1, the foot component 16 comprises a body 34 having opposite side panel parts 36, 38 and 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 cars 46, 48 include recesses for receiving reduced diameter end portions of an adjustment screw 50. One end of the adjustment screw 50 is provided with a turning knob 52 spaced immediately outwardly from the ear 46. A connector block 54 is mounted on the adjustment screw 50. Block 54 includes a transverse bore through which the screw 50 exends. The bore is provided with internal threads which mate with the external threads on screw 50. The block 54 is formed to include a joint component, illustrated in the form of a T-shaped tenon 56. The joint components 30, 32 are complementing mortises. Of course, the mortise and tenon elements may extend horizontally rather than vertically.
When the mounting block 54 is secured to the mouting shank 18, as shown in FIG. 2, rotation of the screw 52 will cause such screw to move axially through the bore in the block 54. Since screw 50 is part of the foot component 16 to move sideways relative to the mounting shank 18, the presser bar 12 and the needle 10.
It is within the scope of this invention to substitute a smooth, nonrotating rod for adjustment screw 50 and size the bore in block 54 so that it will frictionally grip such rod. In such embodiment a sideways force sufficient to overcome the friction forces between the rod and the mounting block is imposed on the foot component 16 in order to laterally adjust it in position.
As best shown by FIG. 2, the bottom surface of block 54 is spaced slightly above the top surface 40 of the foot component 16. The bottom surface of mounting shank 18 is also spaced above the top surface 40. This arrangement permits a limited amount of pivotal movement of the adjustment screw 50 and the foot component 16 secured thereto within the transverse bore in mounting block 54. This movement of foot component 16 is caused by changes in the thickness of material below the foot component 16. Such movement is herein termed a pitch movement since it resembles the pitching movement of a boat.
FIG. 3 shows the mounting shank 18 turned end-forend and in the process of being used for mounting the foot component onto a slanted presser bar 12' of a slant needle type sewing machine.
FIG. 4 shows a low bar type mounting shank 58 sub stituted in place of the high bar shank 18. By definition, a low bar sewing machine is a sewing machine in which the side placed clamp screw on the presser bar is down low relatively close to the sewing surface. Mounting shank 58 is shown to include a joint component 60 of like construction to the joint components 30, 32. It is also of channel form and comprises a front flange 62, a rear flange 64, and an interconnecting web 66. The joint component 60 is formed in the lower portion of the front flange 62. An elongted blind slot 68 is formed in the upper portion ofthe web 66.
FIG. shows a presser bar 12" of the type having a clamp screw 14" in the lower end thereof. Accordingly,
the clamping surfaces (ie the lower end surface of the presser bar 12 and the inner flat surface of the clamp screw head) are horizontally oriented. For use in attaching the foot component 16 to this type of presser bar I have provided a third mounting shank 70. Shank 70 comprises a horizontal panel 72 which is slotted in the same fashion as the webs 24, 66. The shank of the clamp screw 14 is received in such slot and the clamp screw 14" is turned so as to firmly secure the shank 70 in place. Shank 70 also includes a joint component 74 of the same type as joint components 30, 32 and 60.
Accordingly, it can be seen that the mounting shanks 18, 58 and 70 are interchangeably usable for mounting the foot component 16 onto the four standard differing types of sewing machines. Reference is made to by aforementioned US. Pat. Nos. 3,342,151 and 3,349,736 for more detailed disclosures of the various types of presser bars for the different makes of sewing machines.
The foot component 16 is shown to be bascially of the same type as the preferred embodiment shown in my copending application entitled Presser Foot Assemblies, filed concurrently with the present application. It is shown to comprise three presser rollers 76, 78, 80, all three of which are centrally grooved. The groove in the forward presser roller 76 is configured to serve as a guide avenue for a chain of zipper teeth 82 of the type shown in FIG. 6. In FIG. 6 the foot component 16 is shown to be positioned for sewing a tape 84 of an invisible zipper to a piece of material 86. A material advance mechanism (not shown) is located below the material 86 and below that part of component 16 which rests on and presses downwardly against the tape 84.
The space immediately rearwardly of the front roller 76 is open substantially entirely across the width of the foot component body 34. The needle N is positioned in this space during sewing. A substantial laterally open space is necessary because the relative position of the needle N varies an amount greater than the width of the center groove in roller 76. When the assembly is being used for sewing a right tape of a zipper the needle N is located to the immediate right of the right-hand shoulder portion of the center groove in roller 76. When the opposite or left tape is being sewn it is necessary to slide the foot component 16 sideways to the right until the needle is to the immediate left of the left side shoulder.
For a more detailed disclosure of the rollers and variations of the foot component, reference is made to my aforementioned copending application entitled Presser Foot Assemblies. The disclosures of both of my afore mentioned US. Pat. Nos. 3,342,151 and 3,349,736, and of my said application Ser. No. 678,742 and my application entitled Presser Foot Assemblies, are hereby expressly incorporated herein by reference.
Referring now to FIG. 7, the forward end portion of the body 34' may be formed to include slot like openings 88, 90 in the side panels 36, 38 having entrance portions which are slightly narrower than the end shafts 92, 94, and inner circular portions which are slightly larger in diameter than the end shafts 92, 94. This construction permits the ready removal and reassembly of the forward guide roller, designated R in FIG. 7. This makes it possible to also interchange forward guide rollers so that the same foot component can be used for installing different types of zippers or other articles, (e.g. cording, piping, etc.) merely by substituting in a new front guide roller. The guide roller R shown in FIG. 7 is for use in doing ordinary sewing, hence, it is not grooved.
The front portion of the mounting block 54 may be pointed, with the point 96 serving as an indicator or marker which when lined up with some indicia mark 98 formed on the top panel 40, or with the needle N, indicates that the guide groove is properly oriented with respect to the needle. The top panel 40 may be provided with several differing indicia marks 98, each of which is associated with a different one of the interchangeable rollers.
