lt f-will tenet-ed that the retaining action, whether it be through" the spring" clip modifica tion of' Fig.4'or that of Fig 5, is actuallypredicate'd upon the coordinated eife'ct of the two spring clips at therespectiveendsofthefguide, as indicated above. Thus as shown in Fig. 2, for example, a clamping means is aifixe'd to each of theends It" and It" of the guide, andtheretainingfunction and gripping action is in efie'ctaffo'rde'd by the combined function of both; clamping members, relative" to sides I and 'l of the powertable. V v I The" positioning of the guidewith respect to the presser foot is largely determinableby the characteristics of the work contemplated, and the" diagrammatic indications of Figs. 6, 7', and 8 are illustrative of the practicable flexibility and simplicity of attachment and adjustment'attaim able' pursuant to thepres'ent invention.

Concerning the positioning and adjustment'details of the invention, it should be noted that either edge 8 or edge 9 of guide ii may afford the requisite aligning surface relative to the p-resser foot, except where an extremely narrow spacing in the form of a seam or tuck or the like is'desired. Moreover the guide is adapted and intended for transverse positioning across the entire width of the power table. Thus its longitudinal dimension will desirably exceed that of the power table width to an extent sufiicient to permit the guide either to lie upon or proximate to the" power table, with ends [5, I 6', positioned sufficiently close to sides I and? of the table for attaining the requisite gripping and retaining function by the clamping attachments affix'ed to said ends.

in accordance with Fig. 6, which is essentially an enlarged detail of the relative position of guide and presser foot shown in Fig. 1, the guide memher 5 extends transversely of the power table, as previously stated, and is located at the right of the presser foot 4, with the side 8 of the guide being in substantial proximity to the edge 34 of the presser foot. Pursuant to this modification, the adjustment of the guide relative to the presser foot is restricted substantially to the space between the said presser foot 4' and the base 2 of the machine superstructure. As an illustrative indication, and not limitative, this distance may approximate 7 inches more or less for the average power machine, and it will be understood that this may be subject to variation dependent upon the characteristics of a given machine.

With further reference to Figs. 1 and 6,- the dimension of the seam, hem or tuck available by the positioning of the guide as shown comprises approximately the distance between hypothetical line 35 and side 3 of the guide. In this connec-- tion the said line 35 in effect corresponds with the needle path or stitching line, and is positioned substantially midway of the presser foot opening 36. Thus the pertinent hem; seam or tuck may be'subject to enlargement by locating the guide at any predetermined position transversely of the power table, between the edge 34 of the presser foot and the said base 2 of the machine superstructure.

The sketch indicated by Fig. '7 likewise positions the guide 5 to the right of edge 3 1 of the presser foot. However the side 9 of the guide is directed toward the said presser foot, and'infact the edge '34 thereof is located essentially within the rabbet 5. With this adjustment of guide 5, it will be seen that an extremely narrow hein, sand or tuck of requisite uniformity-is attainmedian line of needle eases of e aforesaid h pothetical r this expedient t edge or face 9 of the the rumor the ukeiirniis modification wiii approximate the distance between the'-said*line 35 and the edge or side'- 9" of the guide member. It will nevertheless be" understood that-even though the rabbet is directed toward-edge 34- of the pres'ser "foot, the" guide may be subject to positioning anywherein'the zone 3 3 between the median'line35 of'the' presser foot'and thebase 2' or the machinesuperstructure:

Fig. '8 reveals the guide positii'med to the left of the Dresser foot, thereby affording comparatively unlimited variation in positioning th'eguide transversely of the power table; theliinita'tions being determinedby the length of that portion of thepower table which extends to the left of the presser foot 6: As shown in Fig. 8side- 8 of guide 5 is located in proximity to" edge a? of thepresser foot, and th dimension of the hemseam or tuck, pursuant to this adjustment, comprises the distance between the said median stitching line or' needle path 35"and the said edge 3 of the guide; As the guide 51's adjusted in zone 33 toward'th'e left, the distance between line Stand edge 8 will beprogressivelyincreased, and the pertinent dimension may be .extend'e'dto the point where the guide 5 is positionedalbn the edge 36 of the power table. While the showing of Fig. 8 positions" edge 8 of the guide member toward edge 31 of presser foot 3, it will be understoodthat edge '9 of the guide member likewise may bepositioned contiguous edge 3? of the presser foot, and under such circumstances, the rabbet 6 may be correlated with the said presser foot edge 31. By advantages attainable from the rabbet, especially that of affording. an extremely narrow, uniform hem, tuck or the like, is provided when the guide 5 is located on the left of the presser foot with the said rabbet'fi, on guide, adjacent edge .31 of the presser foot.

Accordingly the positioning of the guide to the left ofthe presser foot perm-its the forming of very narrow, accurate hems, tucks, seams, or any desired stitched spacing of improved uniformity similar to that-afforded by the attachment of the guide to the right of the presser foot, the requisite being that the rabbet 6 shall be contiguous the pertinent presserfoot edge Thus while positioning the uide on the-right-ofthe presser foot afiords the possibilitiesfor progressive variations in the widthof the stitched spacing that are essentialiy limited to the distance between line 35 and the base 2 of the machine superstructure, exclusive-oi the surface width 49 of the guide, the progressivewidth variations at- .tainable through locating the guide on the left of the presser foot are substantially determinable by the distance between line 35 and edge 380i the power table, iikewise' exclusive cfthe' surface width 40 of the guide 5.

Accordingly in View or its flxibili tyiri adaptatio'n both to the right of the presser foot and to the left thereof, the guide 5 comprises a simplified, adjustable device permitting accurate, uniformed stitched spacings, which are subject to predetermined and widely diversified dimensions relative to the needle path or stitching line 35. This is evidenced by its sphere of function extendin longitudinally of the machine power table substantially from edge 38 thereoffto the said superstructure base 2, or difierently stated, from said tableedeete to median line 35 'on the left or the presserroct-ana rromsaio finest-to the superstructure base 2 on the right of the presser foot.

The above description has illustratively referred to guide 5 in the consideration of the various adjustments attainable, as exemplified in reference to Figs. 6, 7, and 8. However it will be clear that guide It is subject to similar adjustable positioning and affords comparable at tributes of flexibility in its adaptations, as well as accuracy and uniformity as a power table guide, since the said guide Ill is to all intents and purposes fundamentally similar to guide 5. As indicated hereinabove, the difference between guide 5 and guide it is predicated on the positionin of the rabbet 6, this being essentially determinable by the characteristics of the sewing machine, particularly with respect to the pertinent location of the machine superstructure together with the presser foot location relative to the transverse dimension of the power table. Differently stated the position of the presser foot with reference to the side or edge 1 or 1' of the power table i determinative of the position of the rabbet along the longitudinal dimension of the guide.

As for the dimension of the guide, its length will be determined, as previously indicated, by the transverse dimension of the power table, with the angularly disposed portions l6, l6 thereof being of sufficiellt length to permit the engagement of the attached clamping means with the sides 1, 1 of the power table. Since the width or transverse dimension of sewing machine tables is essentially standardized, the regulated production of appropriate length guides, pursuant to the invention will be apparent to those versed in the art.

Merely by way of example, the longitudinal dimension of a desirable fabricated guide embodiment applicable for a known sewin machine power table, measured between the inner surface of angularly disposed portions l5, I6, is approximately 16.5 inches. As for the surface width thereof, this dimension may be substantially subject to the dictates of preference, and for the said fabricated guide embodiment, this dimension is approximately /8 inches. As in the case of the other guide dimensions, the height or thickness of the guide may be determinable largely on the basis of preference, and the relevant dimension of the said guide embodiment is approximately inches.

In connection with the angularly disposed pertions I 5, it, the effective length thereof may likewise b subject to variation dependent, for example, upon the dimensional characteristics of the power table, and in the aforesaid guide embodiment the length is approximately 1 /8 inches measured from the under face of the guide-that is, along the inside surface of said portions iii or it and thus excluding the thickness or depth of th longitudinal portion of the guide, which as indicated, is positionable transversely of the tables and may be approximately /4 inch in height or thickness. By way of reiteration, the designated dimensions are merely illustrative of a desirable embodiment and are in no sense critical or in any manner intended to be restrictive of the invention.

The guide member may be fabricated from diversified materials, such as metals, synthetic resins including artificial rubber-type materials, as well as from natural rubber, et cetera. While the clamping means shown in Figs. 4. and 5, preferably of metal derivation, are applicable to any of the indicated types of guide materials, the modification of Fig. 4 is more expediently adapted for metal guide members than for resin or similar guides, in view of the greater amenability to threading manifested by metal articles. As for the clamping attachment of Fig. 5, this is entirely effective with synthetic resins, rubber-type materials and the like, as well as with metals.

While it is not intended to be restricted to any particular type of material for fabrication of the guide, quite desirable metals have been found to be aluminum as well as various alloys thereof, and steel, et cetera. Similarly effective are resin guides, such as those derived from Lucite, phenolaldehyde resins, polystyrene resins, etc.

The procedure involved in the utilization of the invention will conform with the fundamentals pertaining to the supply of fabric to the power table of a sewing machine for the purpose of applying predetermined stitched spacing thereto. Thus the fabric is normally fed transversely of the power table-that is, across the same, and a folded end of the fabric, determinative of the width of the stitched spacing may be positioned adjacent the edge 8, or 9, in accordance with the predetermined adjustment of the guide 5, while the line of stitching is determined by the position of the presser foot. As the folded edge of the fabric is passed across the power table in contact with the pertinent edge of the guide, the stitching, conforming with line 35 is provided by the usual function of the needle in coordination the presser foot.

Whether the guide 5 will be placed to the right of the presser foot or the left thereof, and the relevant positioning of the rabbet S with respect to the presser foot will be subject to the nature of the spaced stitching requirements and determinable by the operator versed in the sewing art.

- Where the distance between line 35 and base 2 of the machine superstructure is approximate? 7 inches, and the spaced stitching desired is less than 7 inches, the guide 5 may effectively be located on the right of the presser foot. This location of the guide is desirable, where it is expedient as above indicated in view of the predetermined width of the spaced stitching, since it permits the length of zone 33 of the power table, extending from the line 35 to edge 38, for the handling of substantial lengths or masses of fabric. Similarly this location of guide 5 is effective for extremely narrow stitched spacings attained through the positioning of rabbet t to the right of and contiguous presser foot 4.

Where the spaced stitching desired exceeds that attainable with th positioning of guide 5 to the right of the presser foot, it is essential that the guide be placed to the left thereof. As previously indicated, this location of guide 5 permits the production of spaced stitching from that of an extremely narrow width when rabbet 5 is contiguous edge 31 of the presser foot, to an unusually enlarged width attainable by the adjustment in the location of guide ii toward the edge 38 of the power table, as aforesaid. As previously indicated the maximum widt of stitched spacing with the positioning of guide 5 to the left of presser foot 4 corresponds with the distance between line 35 and the edge or side of the guide which faces the presser foot, the opposing side or edge of the guide being aligned with edge 38 of the work or power table.

Pursuant to the invention, there is provided a comparatively simple, sturdy guide member, especially applicable in a combinative association :9 witha sewing machine, attachable to the ma- :chine power table, and .afiording .aldiversified rflexibility in (its adjustmentand function not heretofore attainable. Thus the adjustable and variable positioning of the guide member permits an unusually wide latitude in theforming .ofstitched spacings of enhanced accuracy and uniformity, from those of extremely narrow width progressively to those of extremely enlarged width. By virtue of its characteristics, the invention is adapted for use by any sewing machine operator and without any unusual requis'ites of mechanical skill. Moreover indicative of the features and utility of the invention are the many adaptations and flexibility thereof pertinent to'the formulation of spaced stitching of improved accuracy and uniformity and subject to extremely wide variations in the relevant dimensions such as the spacing'width. As previously described, the ramifications of the :said stitched spacings illustratively include the ,production of hems, tucks, seams, edging, as well as the attachment of diversified types of itrimmings .to a garment.

In accordance with the disclosure herein, the details of description pertaining to the various figures of the drawing are directed to preferred modifications of the invention. It will, however, "be understood that these desirable embodiments are intended to be essentially illustrative, rather than restrictive or limitative, and are subject to substantial variation within the purport and scope of the invention herein.
