PICOT EDGING FOR FABRICS.

To all whom it mayconcern:

Beitknown that I, LANSING ONDERDONK, a citizen of the United States, residing at New York, in the county oft-New York, State-ofJNew York, have invented certain new and useful Improvements in Picot Edgings for'Fabrics-, of"which the following is a description, reference being had to the accompanying drawing and to the figures of referencemarked thereon. 1 1 "The invention relates to'new and useful improvements in edgin'gs' for fabrics, and more particularly to a picot edging, that is an edging wherein-there are at intervals spaced projecting loops.

An object of the'invention is to provide a machine-constructed-- picot edging, that is, an edging for fabrics wherein the overefdge stitches are formed with a series of spaced loops which'project laterally beyond certain of the over-edge stitches and :the' ed e of the fabric. 7

the invention is to provide a picot edging'of the above character wherein one ofthe stitching threads is formed into loops which project laterally beyond certain 5. of the i over-edge stitches andtheedge of-the fabric.

"The invention conslsts broadly ama chine-constructed. picot edgingi=- that 5 is, i an edging wherein certain of-the threads -are formed intoenlarged loops which "aresofdis-I posed as to project' 'latera'lly from'i the other loops of the overseamingLst-itchesand later ally from the edge of the fabridand in'the plane offthe fabric." This edging may be con-1 structed from two-thread -orj'three-jthread overseamingf stltches 'and either the needle thread or one:ofthelooperthreads-maybe formed into loops which project beyond the edgeof the fabric sofas to produce-this p'icot edging. The edge'o'fthe fabric may also be folded back Within the limits of the over; seaming stitches, if desired, so that-the -overseaming stitches will inclose the foldededge of "the fabric. H

Referringmore in detailto Figs lto 4,

inclusive,'- of the drawings, my improved" picot edging consists of two threads;: a

needle thread land alooper thread 2; 1A fabric, indicate'd at F, has 'the edging formed thereon. The needle thread is'form'ed into loops 3-which are passed down' through the fabric at. the points 4, and these needle. loops are carried-tothe edgeofthe fabric. The looperfthread is 'formed into loops 5 which pass throughthe respective loo'ps formed in the needle threads. These looper I thread loops are laid on the upper face of the fabric, and the needle thread 'loop asses down through the looper thread loop. This is a well-known form of two-thread over-edge seam and will not need further descri tion. g j v In B lof thedrawings, I have shown the needle at N, the threaded looper at L, and the s reader for spreading the needle loop at Cooperating with the needle,

Thisloop retainer is timed so as to engagea needle thread loop at every third-stitch or puncture of the fabric by the needle. TlllS retainer holds the needle thread loop when the stitch is being set, so that the resultant loop is enlarged or extended, as clearly shown at 6 in Fig- 1. These enlarged or extendedloops 6 project beyond, the other overseaming stitches and the edge of the fabric and lie in the plane of the fabrlc, as shown diagrammatically in Fig. 4.

41 have produced. an edging, therefore, wherein the overseaming stitches encircle the edge of thefabric-and'at intervals of every three stitches, as shown in Fig. -1, the needle loop is enlarged and extended and projects fromthe edge of the fabric, thus forming thepicotedging. WhileI have shown inFig. 1 the loops projecting from the edge of the fabric at every third stitch,

it'will be understood that this spacing of the loops may be'varied without departing from the spirit of the invention.

In Fig. 5 of the drawings, I;have shown a two-thread overseam of the character described in connection with 'Figs. 1 to 4, in-

elusive. In thisshowing of the invention, however, the'retainer'R engages the looper thread between the loops which are projected through the needle thread loops and holds the thread, out so as to form a projecting loop in the looper thread. The projecting loops areindicated at 7 in Fig. 5 of the drawings. These loops are shown as being: formed at every third stitch or puncture ofthe fabric by the needle, but

it is obvious that they may be spaced any desired number of stitches or needlepunctures. This may be accomplished by varying the timing of the movementof the retainer. I

In Fig. 6 of the drawings, I have shown diagrammatically the arrangement of threads shown in Fig. 5, and it will be apparent that the projecting loops 7 lie in the plane of the fabric. 7

In Fig. 7 of thevdrawings, I have shown a slightly modified form. of the invention illustrated in Figs, ,1 to 4, inclusive, in that the edge of the fabric is folded back at F.

- This foldingback of thevedge of thefabric is. within the limits. of the overseaming stitches, and the overseaming stitches enside of the fabric a looper'thread' 8 is formed into a series of loops which are passed through the respective needle loops and these loops 8 are brought tothe edge ofthe fabric where the looperthread 2 is formed into a seriesof loops, each of which is passed through a loop in the looper thread 8, and the looper thread 2 is laid on the upper face of the fabric and secured by the needle threadas described inconnection with Fig. 1. V In this form of the invention shown in Fig. 8, in place" of the spreader, a thread carrying looper L is used and the retainer is timed so as to engage the looper thread,-of;this looper L; The retainer enlarges "or extends the loops into projecting loops '9 which are shown as spaced three stitches or three needle punctures apart. This spacing of the loops may be varied, as. abovestated, 5 i

In F'g. 1 0 of the drawings, I have shown an edging having picotloops formed'which is similar to that shown, in Figs: 8 and 9, with the exception that the tension on the threads have. been changed so that the needle loopsare drawn to the ed e of the fabric and the thread having'the picot loops formedtherein lies wholly along the edge of the fabric. a

Itwill also be understood. that the other looper thread, as in thetwo-threadstitch, may be extended, if desired, to form the projecting loops.

From the above, it will be apparent that I have provided a picot .edging which may be made by a sewing machine, andwherein one of the stitching threads of. theoveredge stitches is formed into loops which are extended or enlarged so as to J project laterally from the edgeof the fabric and lie in the plane of the fabric. These loops are spacedso'as to give the appearance of the well-known picot edging. Y

By making the picot loops from the me dle threads which form the overseaming stitches, said loops are locked so that one loop does not draw thread fromthe' next adjacent loop ifastrain is placed-thereon, that is to say that the thread betweenthe loops is interlocked or concatenated-"with the stitches intervening between the picot loops, and this holds the picot loops at a predetermined size. 4

Having thus described the invention, what is claimed as new is The combination of a fabric and a picot edging therefor, consisting of a needle thread formed into a series of loops extending through the fabric, a looper thread formed into a series of loops extending through the needle thread loops and over the edge of'the fabric where said looper thread loops are entered by the needle loops prior to the passing of the same through I the fabric, one of said threads being formed into loops projecting laterally beyond the i edge of the fabric, said last namedloops being spaced two or more thread concatena- 15 tions apart. I Y In testimony whereof I affix my signature, in the presence of two witnesses.
