6 Claims.

This invention relates to a sewing machine attachment, and more particularly to a feeding guide attachment for simultaneously forming a hem and a pleat spaced from said hem on material fed to the machine.

While the feeding guide of the present invention may be used in connection with a wide variety of fabrics, it is of particular advantage in the fabrication of lightweight curtains of netted material having improved hanging properties. It has previously been customary to form curtains of this type with a wide hem which added considerably to the weight along the edge of the curtain and caused the hemmed edge of the curtain to roll and undulate thereby contributing to a distorted and unsightly appearance. It has therefore been found desirable to form the curtain with a hem of reduced width and also with a pleat spaced from the hem in order to distribute the weight of the curtain more evenly, the pleat having the tendency to straighten out any undulations in the hem. It

s is important that the stitching of the hem and the pleat be done simultaneously so that the hem and pleat will be formed under an even pull to eliminate any possibility of distortion of the pleat with respect to the hem or vice versa.

Accordingly, it is the object of the present invention to provide a feeding guide attachment for a conventional double needle sewing machine for forming the material being fed into a hem fold and a pleat fold spaced from the hem fold, the attachment being securable forwardly of the stitching mechanism of the machine.

It is a further object of the invention to provide a feeding guide attachment of the character indicated which may be easily secured to a conventional double needle sewing machine without modification or alteration of the machine other than the provision of a simple mounting bracket or mounting screw which will not interfere with the normal operation thereof.

Another object of the invention is the provision of a feeding guide attachment wherein the member forming the pleat fold is adjustable with respect to the member forming the hem fold in order to vary the width of the pleat being formed.

The foregoing objects as well as additional objects and advantages inherent in the invention will be readily apparent in the course of the following detailed description taken in conjunction with the accompanying drawings which disclose a preferred embodiment of the invention and wherein:

Fig. 1 is a front view of a feeding guide embodying the features of the invention.

Fig. 2 is a top plan view of the feed guide secured to a double needle sewing machine in operative position the presser foot and a portion of the bed plate of the sewing machine being illustrated.

Fig. 3 is a rear view of the feeding guide.

Fig. 4 is a cross sectional view of the feeding guide taken along line 4-4 of Fig. 2 together with material positioned within the guide for forming a hem fold and a pleat fold spaced therefrom.

Fig. 5 is a perspective view showing the feeding guide and a portion of the sewing machine, the material being fed to the guide and machine being shown partly broken away to illustrate the initial formation of the hem and pleat folds and the final formation of the stitched hem and pleat.

Referring in greater detail to the drawings, the feeding guide is formed with a mounting arm H) for adjustably securing the feeding guide directly to the bed plate I l of a double needle sewing machine !2 or to a mounting bracket l3 secured to the bed plate I I and having a supporting arm lac, the latter arrangement being shown in Figs. 2 and 5.

Secured to mounting arm ID in any suitable manner, as by soldering, is the hem-forming member of the feeding guide generally indicated by reference numeral l4. Hem-forming member l4 may be conveniently made from sheet metal suitably formed to define a substantially plane, horizontal portion l5 for supporting the fabric and a curved portion I6 looped or turned over upon itself as shown at H to define an upper wall Mia and a lower wall I617. Plane portion I5 is preferably provided with a rearwardly inclined feeding edge l5a terminating in a straight folding edge lib for forming a pleat as will be fully described hereinafter. The inner end of curved portion 56 is also looped or turned over upon itself inwardly and downwardly as shown at l3 and preferably tapers gradually from an opening of maximum width l8a at the front or mouth of the feeding guide to an opening of minimum width I8bat the back or delivery end of the feeding guide for the purpose to be fully indicated hereinafter. A U-shaped inner member i9 is disposed within curved portion It between upper and lower walls Ilia and I 6b respectively thereof, as by soldering the free ends of said member to the inner looped-over end 18 of curved portion 16. It will be noted that lower wa l 1. a 9i inner member l9 projects for some distance into mouth opening [8a in order to turn the raw edge of the fabric inwardly in forming the hem thereon, as clearly shown in Figs. 4 and 5. Thus a curved, U-shaped recess or channel is formed between curved portion I6 and inner member H) of forming member l4 whereby the edge of the fabric F, when introduced within said forming member, is folded back upon itself to form a hem fold which is secured by a line of stitching 20 (see Fig. as the fabric is fed through the sewing machine. In its passage through forming member [4, the raw edge of the fabric is turned inwardly over lower wall I911 of inner member l9 and since the inner loopedover end I8 of curved portion I'6 tapers gradually from the relatively large mouth or entrance end l8a to the relatively small delivery or exit end [819, said raw edge of the fabric is progressively tightly rolled inwardly and finally secured in place by the same line of stitching 20 which forms the hem, as clearly shown in Fig. 5.

The pleat forming member 2! may be mounted directly on the bed plate ll of the sewing machine by means of a slotted arm 22 adjustably secured by a set screw 23, as shown in Figs. 2 and 5 or alternatively may be adjustably mounted on a portion of hem-forming member I a such as mounting arm I 0 thereof or even on an extension (not shown) of mounting bracket 13. In any event pleat forming member 2! underlies hemforming member l4 and is formed with an inwardly turned, overhanging portion 2 adapted to overlap plane portion 15 of said hem-forming member in order to form a pleat fold in the fabric spaced inwardly from the hem fold.

Portion .24 is preferably formed with a rearwarolly inclined feeding edge 24a terminating in a straight folding edge 24b. The width of the pleat fold will be determined by the extent of overlap between folding edge Z lb of pleat forming member 2! and folding edge I52) of plane portion l5 of hem forming member it. The particu-, lar width of the pleat to be formed in any given case may therefore be predetermined by adjusting the pleat forming member 2| with respect to folding edge I51) of hem forming member M by means of set screw 23 passing through slotted arm 22.

As the fabric or other material is fed through the f eding guide and sewing machine, the pleat fold will be secured by a line of stitching 25 spaced inwardly from and substantially parallel to the line of stitching 25 simultaneously forming the marginal hem. Thus, any undue pull or distor tion of the pleat with respect to the hem or vice versa is minimized.

The presser foot 26, needle bar 21; the pair of needles 28, and sewing machine housing 25 are shown in sufficient detail to appreciate the cooperation of the feeding guide therewith.

Since certain modifications may be made in the feeding guide of the invention without departing from the scope thereof, it is intended that all matter contained in the foregoing description and shown in the accompanying drawings be interpreted merely as illustrative and not in a limiting sense.
