9 Claims. (Cl. 1122) This invention relates to sewing machines and, more especially, to an improved attachment for sewing machines to facilitate the sewing of endless neck bands, arm bands and the like to marginal portions defining openings in garments, such as T shirts, polo shirts, sweaters and the like.

As is well known, garments of the character described are usually knitted and the neck bands and arm bands therefor are also knitted usually in the form of a rib knit, whereby the garments and the neck bands or arm bands are inherently elastic. Sewing machines currently used for securing neck bands, arm bands, and the like to knitted garments are provided with a reciprocating cutter blade immediately adjacent the needle thereof for cutting away excess material from the garment and the band being attached thereto immediately in advance of the needle, which needle usually forms an overedge seam. A sewing machine of the type usually used for this purpose is disclosed in U. S. Patent No. 2,157,373 to J. P. Weis, dated May 9, 1939.

Heretofore, in order to attach an aim band or neck band to the marginal portion of a garment, it has been necessary for the operator to guide the garment and the band simultaneously, by hand, while maintaining the garment and the band under tension and, due to the human element, it has been impossible to maintain the garment and the band under uniform tension throughout each sewing operation and it has also been extremely diflicult for the operator to accurately position the band and the garment relative to the sewing needle throughout the sewing operation. Consequently, this sewing operation has been excessively time consuming and expensive and, in many instances, the stitches have been irregularly formed and unevenly spaced and the overedge seam has been irregular.

It is, therefore, an object of this invention to provide an improved attachment for a sewing machine of substantially the character described comprising a frame adapted to be removably attached to the frame of the sewing machine and which may be swung into and out of operative position and also having releasable means thereon for latching or locking the frame in operative position. When in operative position, a first or primary guide element, preferably in the form of a roller projecting horizontally from the frame of the attachment, is positioned closely adjacent the sewing needle and in front of the presser foot and the frame also has at least one additional guide element which is adjustable relative to the primary guide element to vary the displacement therebetween for accommodating garment openings and corresponding bands of various sizes whereby the marginal portion of the garment defining a parti ular opening and the corresponding band may be positioned about the guide elements and held under tension therebetween with the portions of the marginal portion of the garment and the band being positioned beneath the presser foot immediately adjacent the primary guide element.

ice

At least the primary guide element has an abutment or enlarged portion thereon immediately adjacent the frame of the attachment and against which the marginal edge defining the opening in the garment and the edge of the endless band is positioned whereby the garment and band are maintained in a uniform position relative to the sewing operation and also whereby the marginal portion of the garment and the neck band are maintained under uniform tension throughout the sewing operation as they are moved past the trimming and sewing instrumentalities by the usual feed dog.

It is another object of this invention to provide an attachment of the character described wherein the frame of the attachment comprises an upright portion and a substantially horizontally extending portion disposed intermediate the ends of the upright portion and extending substantially rearwardly therefrom. The portion of the upright portion disposed below the level of the horizontal portion of said frame of the attachment has a primary roller or guide element attached thereto and the upper portion of the upright portion of said frame and the horizontal portion of said frame each have respective second and third guide elements or rollers mounted thereon for adjustment longitudinally of the corresponding frame members.

Novel means are provided for simultaneously adjusting the second and third guide elements relative to each other and relative to the primary guide element including respective first and second threaded shafts extending longitudinally of the upright and horizontal portions, respectively, of the frame which shafts threadably penetrate respective guides or supports for the first and second guide elements and wherein gear means are provided for interconnecting corresponding ends of the two threaded shafts with a manually rotatable member, such as a hand wheel or knob, provided with a gear thereon for engaging the firstnamed gear means whereby, upon rotating the manually rotatable means, both the first and second guide elements are moved toward and away from each other simultaneously.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds when taken in connection with the accompanying drawings, in which Figure l is a top plan view of a sewing machine showing the improved attachment mounted thereon and in operative position;

Referring more specifically to the drawings, the improved garment-and-band guiding apparatus is shown in association with a sewing machine of a type manufactured by Willcox & Gibbs Sewing Machine Company, 214 West 39th Street, New York 18, New York, and substantially as disclosed in said Patent No. 2,157,373. Accordingly, only so much of the sewing machine will be described in the present application as to provide a clear understanding of the present invention.

The sewing machine comprises a main platform or bed plate 1%) which is supported on a main frame broadly designated at 11,'said main frame being in the form of a housing containing conventional operating mechanisms therein, not shown, for driving the sewing and trimming instrumentalities. It will be observed in Figure 1 that the front edge of the platform or bed plate is cut away to form a recess 13 therein which also defines a substan:

tially rectangular projection 14 on the platform 10, this projection 14 being spaced to one side of the sewing instrumentalities and being used in this instance for supporting the improved garment-and-band guiding apparatus to be later described.

The sewing machine illustrated in the present drawings is of a type particularly devised for forming a socalled overedge seam and the improved apparatus is provided for guiding endless bands such as the band B in Figure 2 and the marginal portions of garments'such as the portion of the garment G shown in Figure 3 past the sewing and trimming instrumentalities during the forming of the overedge seam, to attach the marginal portion defining an opening in the garment G to the band B.

The sewing instrumentalities include a reciprocating or oscillating needle 15 supported by a conventionally driven oscillating needle carrier 16. Yarn Y is directed to the needle 15 in a manner fully disclosed in said patent. The

.needle 15 reciprocates or oscillates through a suitable opening provided therefor in a conventional throat plate carried by the bed plate or platform 10 and cooperates with a conventional looper, not shown in the present application, but being clearly shown in said patent, to form stitches.

The band B and the marginal portion of the garment G are fed in timed relation to movement of the needle 15 by means of a conventionally driven feed dog 21 (Figure 2) which reciprocates in the usual slot provided therefor in the throat plate 20 and the work is held against the throat plate at the stitching zone by means of a conventional presser foot fixed on the front end of a spring carrier-arm 23 whose front end is resiliently urged downwardly by conventional means, not shown, to thereby resiliently urge the presser foot 22 toward the throat plate20. 9 V

The trimming mechanism is disposed closely adjacent and forwardly of the free end of the needle 15 and comprises an upper movable cutter 26 adjustably mounted on the front end of a cutter carrier arm 27 mounted for pivotal and axial movement with a shaft 30 supported in upstanding lugs 31 (Figure 2) and 32 (Figure l) on the bed plate or platform 19. The upper cutter 26 co operates with the cutter 34 (Figure 3), as shown in said patent, for trimming excess material from the edges of the garment u and band 8 immediately prior to the forming of the overedge seam thereon.

-The improved work guiding attachment or garmentand-band guiding attachment comprises a frame broadly designated at 49 which is preferably made from rigid strap material such as strap metal and which comprises a main upright or substantially vertical arm 41 and a main substantially horizontal arm 42 which projects rearwardly from the medial portion of the upright arm 41. It will be noted that the arm 42 extends at an angle rela tive to the longitudinal axis of the sewing machine and, thus, the upright arm has a lower portion 43 integral therewith which is bent slightly in a helical manner immediately below the arm 42.

The lower end of the portion 43 of the upright arm 4?. has an outwardly projecting plate 44 integral therewith whose outer end-has a hole 45 therein (Figure 5) for reception of a bolt 46 for pivotally securing theouter end of the plate portion 44 of the frame 40 to the lower surface of the projection 14 on the bed plate or platform 10. It might be stated that the projection 14 has a pair of spaced holes 47, 48 therein (Figure 1), these holes 47, 48 normally being provided in the particular type of sewing machine illustrated in the drawings when such sewing machines are manufactured whereby the improved guiding apparatus may be readily attached to the sewing machine without any alterations being made to the sewing machine. The hole 47 is penetrated by the bolt 46 heretofore described.

In order to releasably lock the improved guiding apparatus in the operative position shown in Figures 1, 2 and 3, a spring-loaded, manually operable detent 51'is provided which is adapted to fit in the hole 48 heretofore described when the frame 40 is in the operative position. The spring-loaded detent 51 is best shown in Figures 4, 5 and 8 wherein it is shown in the form of a vertically disposed rod or pin whose lower end is rounded and which is mounted for vertical sliding movement in an angle clip or angle plate 52 and a restricted portion 53 in the upper end of a tubular guide 54. The lower end of the tubular guide 54 is suitably secured to or formed integral with the horizontal portion of the angle, clip or angle plate 52 and the lower end of the vertical leg of the angle clip or angle plate 52 is suitably secured to or integral with the horizontal plate 44 of the frame 40.

The detent 51 has an enlarged medial portion55 thereon whose upper surface is engaged by a compression spring 56 whose upper end bears against the lower surface of the restriction 53. Thus, the compression spring 56 normally urges the pin 51 downwardly, such downward movement being limited by engagement of the enlarged portion 55 with the upper surface of the horizontal portion of the angle plate 52. The upper end of the pin 51 preferably has a suitable knob 57 thereon which is adapted to be grasped by the operator for lifting the pin 51 out of engagement with the hole 48 in the projection 14 on the platform 10 when the operator desires to swing the entire improved guiding apparatus out of the way of the stitching zone for the purpose of threading the needle or for any other desired purpose.

It will be noted that the vertical leg of the angle clip or angle plate 52 also serves as a stop for limiting rearward movement of the frame 40 when it is swung to the operative position shown, since the vertical portion of the angle plate 52 then engages the front edge of the projection 14 on the platform 10 and thus positions the pin or detent 51 so it will readily drop into the hole '48 when the knob 57 is released by the operator.

When the improved apparatus is in the operative position shown in Figures 1, 2 and 3, it will be noted that the portion 43 of the vertical leg of the arm 40 extends through the recess 13 heretofore described and is disposed forwardly of and to one side of the sewing zone. Theframe 44 carries a plurality of spaced article guiding elements which are shown in the form of rollers including a lower or primary guide roller or guide element 69 and second and third or upper and intermediate guide elements or guide rollers 61, 62. Each of the rollers 60, 61, 62 is preferably provided with an enlarged flange 63 on its inner end adjacent the frame 40 and, although the rollers 60, 61, 62 are shown asbeing smooth at their medial portions in Figures 1 and 3, it is to be understood that they may be roughened or knurled or treated in any desired manner so they may have a relatively high coeflicient of friction to maintain the marginal portions forming.openings in garments in engagement therewith. In this instance, the outer end of each of the rollers 60, 61, 62 has a tapered enlarged portion 64 thereon which is preferably relatively sharp at its outer periphery and is of substantiallyless diameter than the diameter of the corresponding inner flange 63. 'I

These sharp flange portions 64 on the rollers 60, 61,

62 tend to hold the fabric on the rollers 60, 61, 62 after it has been properly positioned by the operator. It will be best observed in Figures 5, 6 and 7 that the guide elements or rollers 69, 61, 62 are mounted on respective substantially horizontally disposed spindles or shafts 70, 71, 72. The inner end of shaft 70 is adjustably secured in a vertical adjustment slot 74 provided in the lower portion 43 of the upright arm 41 of frame 40 by means of a pair of lock nuts 75 threadably mounted on the threaded inner end of the shaft 70 and which engage the distal surfaces of washers 76 and which washers, in turn, engage opposite sides of the portion 43 of the upright arm 41 of the frame 40.

The outer end of each of the shafts 70, 71 72 has an enlarged portion 77 thereon whichis shown in the form of a washer fixed on' the outer end of the corresponding shaft by means of a screw 80. Thus, the washers or enlarged portions 77 retain the rollers 60, 61, 62 on the respective shafts 70, 71, 72. It will be observed in Figures 6 and 7 that the inner ends of the shafts 71, 72 are also threaded and have respective pairs of lock nuts 81, 82 threadably mounted thereon which serve as enlarged inner portions on the respective shafts 71, 72 for limlting endwise movement of the rollers 61, 62 on the respective shafts 71, 72.

It Will be noted that the vertical and horizontal arms 41, 42 of the frame have respective longitudinally extending slots 83, 84 therein which are loosely penetrated by the inner ends of the respective shafts 71, 72. Shaft 72 also loosely penetrates the web portion of a substantially U-shaped or channel-shaped indicator element 85, the web portion of which is loosely disposed between the innermost lock nut 82 and the upright arm 41 of the frame 4%. it will be observed in Figure 3 that one of the legs of the indicator element 85 is pointed, as at 86, to indicate the position of the roller 61 relative to the upright arm 41 of the frame 40, the pointed portion 86 of the indicator element 85 being adapted to traverse an indicator plate or bar 87 fixed relative to and extending longitudinally of the upright arm 41 of the frame 40. The indicator plate or bar 87 is suitably graduated as shown in Figure 3 to indicate the position at which the roller 61 should be located relative to the roller 60 for accommodating bands and garment openings of predetermined sizes.

Suitably secured to, or integral with, the arms 41, 42 of the frame 40 are respective pairs of spaced bearing blocks 90, 91 and 92, 93, the bearing blocks 90, 92

being disposed adjacent the free or distal ends of the respective arms 41, 42 and the bearing blocks 91, 93 being disposed adjacent the junctures of the arms 41, 42 with the bearing block 91 spaced above the level of the arm 42. It will be noted in Figures 1, 2 and 4 that the arm 41 of the frame also has a bearing block 94 fixed to the front portion thereof and extending in spaced substantially parallel relation to the block 93. 7

Thus, the bearing blocks 91, 93, 94 are arranged to provide a space therebetween in which bevel gears 95, 96, and 97 are disposed, the two gears 96, 97 being relatively large as compared to the gear and disposed in substantially axial alinement with each other and engaging opposed sides of the smaller bevel gear 95. The gear 95 is fixed on the lower end of a shaft 100 which is threaded substantially throughout its length and the gears 96, 97 are fixed on the proximal ends of respective shafts 101, 102. A substantial portion of the shaft 101 is also threaded.

The distal ends of the shafts 100, 101 are journaled in the bearing blocks 90, 92 and the proximal end portions of the shafts 100, 101 are journaled in the respective bearing blocks 91, 93. The indicator plate or bar 87 is suitably secured to the front surfaces of the hearing blocks 90, 91, as by screws 193. The shaft 102 is journaled in a sleeve or bushing 104 fixed in the bearing block 94 and a suitable hand-wheel, knob or crank 6 means 105 is fixed on the outer or front end of the shaft 102.

Now, referring again to Figures 6 and 7, it will be be observed that the shafts 71, 72 on which the respective rollers or guide elements 61, 62 are rotatably mounted, have respective reduced threaded inner .portions 106, 107 which are threadably embedded in respective guide blocks 110, 111 threadably penetrated by the respective threaded shafts 100, 101. The guide blocks 110, 111 are adapted to slide against the respective arms 41, 4-2 of the frame 40.

It will be noted that when the improved guiding apparatus occupies the operative position shown in Figures 1, 2 and 3, the lower or primary roller 60 is positioned closely adjacent and forwardly and above the level of the presser foot 22. It will be noted in Figure 2 that only the band B is shown mounted on the guide elements 6%), 61, 62 for purposes of clarity although it is apparent by referring to Figure 3 that both the marginal portion defining an opening in a garment G and the band B are mounted on the guide elements or rollers 60, 61, 62 during the sewing operation.

It is thus seen that, in operation, the band B and the marginal portion defining an opening of a garment G are positioned about the guide elements or rollers 60, 61, 62 and extend downwardly from the lowermost of the guide elements 60 and beneath the presser foot 22. In order to accommodate bands B and marginal portions defining openings in garments of varying sizes, it is merely necessary for the operator to rotate the knob or hand-wheel 105 in either direction to vary the displacement between the three guide elements or rollers 60, 61, 62. For example, by rotating the hand-wheel 105 in one direction, the two variable guide elements 61, 62 may be moved downwardly and forwardly, respectively, to

decrease the distance therebetween and the distance from each of the latter elements to the primary element 60. Since it is desirable that the intermediate roller or guide element 62 remains relatively close to the vertical plane of the presser foot 22 so the article being sewn extends at a relatively steep angle from the rear edge of the presser foot to the intermediate element or roller 62, it will be noted that the gears 97, 96 are substantially twice the diameter of the gear 95 so the upper roller or guide element 61 will move twice as far, in either direction, as the intermediate guide element or roller 62 whenever the hand-wheel or knob 105 is rotated in either direction. It is also apparent that the point 86 on the indicator element 85 readily serves to indicate to the operator the proper position for the upper roller or guide element 61 to accord proper displacement between the rollers 60, 61, 62 to accommodate garment openings and bands of predetermined sizes.

In the drawings and specification there has been set forth a preferred embodiment of the invention and, although specific terms are employed, they are used in a generic and descriptive sense only and not for purposes of limitation, the scope of the invention being defined in the claims.
