1 claim. (ci. 11a-1) This invention relates to trimmings, edgings, and like materials of the type known as fagoting and commonly used byworkers in the needlecraft arts for the adornment of articles of wear- 5 ing apparel and stitched household draperies,

linens, etc.

The invention has for an object to provide an ornamental trimming or fagoting strip which may be readily made in any desired length in l a variety of patterns by an unskilled person with the aid of a simple hand forming frame used in conjunction with a household sewing machine.

Another object of the invention is to provide a trimming strip of openwork formation which l may. without distortion, be readily and accurately guided to the needle of a sewing machine in the attachment of the trimming strip to fabric material, either as a surface ornamentation, as an edging, or as an insertion.

With the above and other objects in view, as will hereinafter appear, the invention comprises the devices, combinations and arrangements of parts hereinafter set forth and illustrated in the accompanying drawings of a preferred embodi- 25 ment of the invention, from which the several features of the invention and the advantages attained thereby will be readily understood by those skilled in the art.

This application is a division of applicants 30 copendlng application Serial No. 713,843; filed March 3, 1934.

It is to be understood that the term strand" is used herein in a broad sense including any narrow strip-like material, such as tape, ribbon,

35 cord, thread or yarn, of woven, knitted, braided or twisted texture.

According to the preferred embodiment of the invention illustrated, there is provided a trimming strip forming frame or forked member comprising an end-member or handle I having a long centrally projecting prong or tongue 2 terminating at its free end in a T-head 3. Fulcrumed on the pivot-pins 4 which are fixed to the handle I are the side-bars or prongs 5a, 5'0 each of which has the cross-'sectional form of an angle-bar having a flat base-portion 5 and an upstanding toothed portion 5 at an acute angle to the baseportion, as shown in Fig. 4. The toothed upstanding portions 5 of the side-bars are spaced apart and each is spaced from the intermediate tongue 2 to provide narrow stitch-receiving gaps 6. There is pivoted at l to the free end of the side-bar 5a, a distance piece 8 of U-shaped crosssection having a channel 9 which embraces or receives the ends ofthe side-bars, as well as the T-head of the tongue 2. The tip end I0 of the side-bar 5b projects through a hole II in the distance piece 8 and is thereby held in contact with one side of the T-head 3y which latter is held in contact with the other side-bar, as shown in Fig. 1. The Width of the T-head 3 is such that when the distance piece 8 is closed, the tooth-rows of the side-bars are in parallelism. The distance piece 8 may be formed with one or more additional holes I2 to receive the tip-end Ill of the side-bar 5b when it is desired to adjust the sidebars to angular or tapered relationship with oneanother, as shown in Fig. 2.

There is secured in fiat superposed relation upon the handle I, by the riveted Shanks of the pivot-pins -4, a leaf-spring I3 which is provided 55 with rib-forming-strand-positioning slots I4 each in line with a respective stitch-receiving gap 6, Fig. 1. The distance piece 3 also has rib-forming-strand-positioning notches I5 each cut in line with a respective one of the gaps 6. The distance piece l may be'further provided with a notch I6 for the starting end of the trimming-base-forming-strand I1, Fig. l and with one or more additional notches I9, Fig. 2, for one of the rib-forming strands I9.

Referring particularly to Fig. 6, it will be seen that the upstanding portions 5" of the side-bars are provided at equidlstant intervals with vertical slots 2II to form the teeth 2I the upper ends of which have slightly beveled corners 22; the teeth 2i being substantially rectangular in form but without sharp corners or edges. 'I'he iirst few teeth 2|' at the starting end of the frame, remote from the handle I, have their upper ends rounded on more than the remaining teeth 2| to more easily receive the end-loops of a previously formed and stitched length of trimming strip for continuation of the manufacture of the trimming strip to any desired length. The slots 20 extend substantially all the way down to the base portions 5' of the respective side-bars, so that the trimming base strand I1 will, when looped upon the teeth of the frame, lie substantially in contact with the intermediate tongue 2. It will also be noticed that the flat base-portions 5 of the sidebars lie in a common plane with the intermediate tongue 2 so that both the side-bars and tongue may rest iiat upon the cloth-plate of an ordinary sewing machine with which the device is intended to be used.

The sewing machine may be of the usual family or domestic type having the needle-bar 23 carrying the needle 24 which reciprocates vertically through the needle-hole 25 in the throat-plate 26. The machine has the usual flat bed or cloth-plate 21 and four-motion feed-dog 28 which operates through the usual feed-dog slots in the throatplate 26.

For use with the present trimming strip-forming frame, the usual spring-pressed presser-bar 29 of the sewing machine is preferably fitted with a special presser-foot 30 having a flat sole-plate 3i and upturned toe 32. The sole-plate 3| is provided in its longitudinal center line with a needle-hole 33 and on each side of its longitudinal center line with a guide slot 34 for the upturned toothed portions 5" of one or the other of the side-bars of the trimming strip forming frame, there being between the slots 34 a narrow central bar 35 which is provided in its under face with an inverted V-shaped groove 36 adapted to automatically guide the rib-forming strands I9, one at a time, to the needle so that the latter will stitch through and longitudinally of such strands. The slots 34 in the presser-foot are so spaced laterally of the needle-hole 33 that the rib-forming strands I9 will be guided longitudinally above the respective stitch-receiving gaps 6 in the forming frame.

To use the device for making a trimming strip with parallel edge lines, the frame is adjusted with its side- bars 5, 5b in parallel relation, as shown in Figs. 1 and 7. A trimming base strand I1 of material is then knotted at its starting end and engaged in the starting notch I6 in the distance piece 3 remote from the handle I. The strand I1 is then looped back and forth by hand around the teeth of the side-bars and progressively lengthwise of the latter to form the desired pattern. The substantially rectangular form of the teeth 2I and the inclination of the teeth of each row away from the teeth of the other row,

-are of great assistance to the'operator in the hand-looping operation, as the loops may be formed upon and close to the upper ends of the teeth and readily slide down to the bases of the teeth. The rib-forming strands I9 are next placed in the notches I5 of the distance piece I and stretched lengthwise of the frame and slipped into the notches I4 of the spring I3 so as to overlie the legs of the loops of the base strand I1. 'I'he rib-forming strands I 9 should be initially cut into lengths at least equaling the length of the trimming strip desired to be made. which may be many times the length of the forming frame. The same or different strands or cords may be used for the base and rib-forming strands. The side-bars 5a, 5b are 'preferably stiffened, to resist bending or deformation under the cross-strains of the looped base strand I1, by having their fiat base-portions 5 widened beam-fashion centrally of the lengths of the side-bars, as shown in Figs.' 1 and 2. l

When the frame has been wound as directed it is presented to a sewing machine fitted with the presser-foot 30 and a line of stitches is passed through one rib-forming strand to secure the latter to the legs of the base-strand loops. The stitching thread or threads are then cut and a second line of stitching is passed through the other rib-forming strand to secure it to the legs of the base-strand loops in parallelism with the first rib-forming strand. After both rib-forming strands have been stitched to the looped base strand the frame is removed from the machine. and the stitched length of finished trimming is stripped from the teeth of the frame.

To assist in the stripping operation there may be provided a stripper 31, Figs. 11, 12 and 13, made of two pieces of sheet-metal riveted together at 38 and having lower and upper offset portions 39, 40 spaced apart to form a passageway 4I, Fig. 12, for the base-portion 5', of the side-bar 5b. The offset portions 39, 40 of the stripper have spaced upstanding lips 42, 43, respectively, forming a passageway for the upstanding toothed portion 5" of the side-bar 5b. Each of the lips 42, 43 has an inclined edge 44 which cams the loops of the trimming strip upwardly, Fig. 1l, and dislodges them from the teeth of the side-bar 5b. The trimming strip may then be readily removed from the teeth of the other side-bar 5*. It is of course understood that the starting ends of the strands in the positioning notches of the piece I must be severed and the distance piece 9 opened before the stripper is applied to the side-bar 5b. 'I'he inner lip 42 of the stripper should preferably fit rather closely against the toothed upstanding portion 5" of the frame side-bar. so as to hold the outer upstanding lip 43 of the stripper closely thereagainst in order that the inclined edge 44 of the outer lip may engage and lift the ends of the loops of the trimming strip. It may be desirable to provide the stripper with a spring tongue 45, Fig. 14, to resiliently engage the inner face of the toothed upstanding portion 5" of the frame side-bar 5b through an opening 46 in the inner lip 42.

After the stitched portion of the trimming strip is removed from the frame, the last few loops stitched may be easily applied by hand, aided by the pointed tongue 41 of the stripper, to the specially rounded end-teeth 2|' adjacent the distance piece 9, which is then closed to the position shown in Fig. 1. The hand-looping of the base strand l1 is then continued to again fill the frame, after which the rib-forming strands are drawn taut and slipped into the positioning notches Il and under the spring I3. The stitching is again resumed at the points where it was previously stopped and continued to the handle end of the frame. There is no danger that the stitching will be carried too far since one or the other of the upstanding pivot-pins Il will engage the upturned toe $2 of the presser-foot and arrest the feed of the frame before the needle reaches the end of the respective stitchingreceiving gap 8 in the frame. The stripping, looping and stitching operations may be repeated until the trimming strip attains the desired length.

It will be observed in Fig. 8 that the rising feeddog 28 engages the intermediate tongue 2 of the frame and lifts the -latter under the downward yielding pressure of the spring-pressed presserfoot 30. It is found in practice that the frictional engagement of the feed-.dog teeth with the under side of the tongue 2 'exceeds that of the looped base-strand Il vwith the under face of the presserfoot 30, so that the feed-dog effectively feeds the loaded frame through and under the presser-foot. Of course, the tongue 2 may, if necessary, be sand-blasted or otherwise roughened on its under face to increase the grip of the feed-dog thereagainst. To make a tapered trimming strip, the frame is set up with the side-bars 5*, 5b inclined to one another, as shown in Fig. 2. The trimming base strand Il is wound or looped around the teeth of the side-bars in any desired pattern and the ribforming strands I! are stretched longitudinally of the respective side-bars between the notches I5, I8 and slots il in the spring Il. The tongue 2 is then shifted into parallelism with the side-bar i and one intermediate rib-forming strand Il is stitched to position across the legs of the base strand loops. When the stitching of the first ribforming strand is completed, the side-bars are swung from full to dotted line position, Fig. 2, to shift the other side-bar i* into parallelism with the tongue 2. 'I'he stitching of the second ribforming strand to the looped base-strand is then proceeded with. A

A great variety of trimmings may be produced by use of the present device. In Fig. 15 there is illustrated the ladder" type of trimming having spaced parallel cross-bars 4B. Fig. 16 illustrates the closely formed figure 8 type of parallel trimming with the angularly related or zigzag cross-bars 49. Fig. 17 shows an open form of figure 8 tapered trimming. The parallel type of trimming oi' Fig. 18 is formed by using an additional base-strand I1 which is looped onto the frame so that the legs of the loops cross the legs of the loops of the base-strand I'I to form a series of Xs between the rib-forming strands II.

Any of the trimming strips according to the invention may be readily and accurately applied as an edging to a body-fabric by merely superposing the trimming strip upon a body fabric, and presenting the two to the sewing machine, as shown in Figs. 22 and 23, using the special presserfoot 30 to automatically guide one of the rib-forming strands of the trimming to the needle which sews the trimming to the body-fabric Il with a line of stitches il. The body-fabric Il is then folded around the line of stitches Si to the position shown in Fig. 24 and pressed to position or additionally stitched by a line of stitches l2. Fig. 19 illustrates a face view of the edged body-fabric of Fig. 24. Obviously by repeating the operation and using an additional piece of body-fabric Il' the trimming strip may be applied as an insertion. This effect is shown in Fig. 20 in simulation of zigzag cross-bar hemstitching, and in Flg. 21 in simulation of parallel cross-bar hemstitching. Inasmuch as the trimming strip may be initially formed with strictly parallel rib-forming strands I8, and inasmuch as such strands are used to guide the subsequently formed lines of stitching 5I and 52 used to attach the trimming strip as an edging or as an insertion, it follows that a hith degree of accuracy is readily attained in making insertions of uniform width or in applying edgings with uniformity.

variously colored threads, cords, twists. yarns and the like and combinations of the same may be used in forming the base of the trimming. The rib-forming strands may be of any suitable cylindrical cord-like material having sumcient size or thickness and body to be automatically.

guided by cooperation with a grooved guiding element of a sewing machine.

So far as I am aware. I am the first to provide an open-work trimming strip and means for chine guiding element to control the position of a subsequent line of sewing machine stitches in the attachment of the trimming to a body-fabric.

The invention is not to be understood as limited to the specific forms and arrangements of parts or to the details of construction shown and described as such forms, arrangements and details Having thus set forth the nature of the 'in-vention, what I claim herein is:-

A sewed trimming strip comprising, an ornamental base-strand of material looped back-andforth widthwise of the strip and progressively lengthwise `oi! the strip. a pair of cylindrical ribforming strands of material disposed wholly on one outer face of the strip and extending straightaway lengthwise of the strip across the legs of the base-strand loops wholly within the ends of the loops, and lines of sewingmachine stitches penetrating the respective rib-forming strands and securing the rib-forming strands solely to the looped base-strand. said rib-forming strands having sufficient thickness and body for subsequent cooperative engagement with a grooved sewing mafabric material.
