293,903. 1940, Serial 26, 1938 A 2 Claims.

This invention relates to edge ornamentation for fabrics and also to methods of producing such ornamentation, the present application belng a division of `a copending patent application Serial No. 293,903, filed -by me on September 8, 1939.

My present invention has for its aims the provision of an ornamental edging in which spaced projecting figures simulative of sunbursts with radiating digits, are formed by a continuous succession of chain stitches; and to evolve a simple method whereby such ornamentation can be produced.

In the drawings,

Fig. I is a view showing one type of my improved fabric edge ornamentation on an enlarged scale.

Fig. II is a view similar to Fig. I, showing a modification.

Fig. III is a fragmentary diagrammatic view in plan of the sewing machine with the aid of which the ornamentation can be produced; and

Fig. IV is a fragmentary view in section taken as indicated by the angled arrows IV-IV in Fig. III

Referring first to Fig. I of these illustrations, the ornamental edging of my invention there shown, is characterized by spaced serially-connected gures M `each simulating a sunburst or palm leaf with radially-extending digits L, L and L2 anchored at a kcommon point P immediately inward 0f the edge E of the fabric designated F. Each digit is inthe form of a iiat, substantially-closed loop composed of a succession of chain stitches Ht, IH, H2, H3, H4, and H5, the ornamentation being formed, in this instance, from two threads T and T whereof one is stippled for convenience of distinction from the other. It is to be particularly noted that the two threads are continuous, and that the first and last loops H0 and H5 respectively of each digit penetrate the fabric F at the common point P to which reference was made above. The connections C between the Sunburst figures M are likewise composed of a succession of chain loops H1, H8, H9, |20, |2| and |22, and are of a length in excess of the spacing of said figures, and take on the appearance of obtuse angle projections beyond the fabric edge E, the component segments or arms of each such angle projection radiating, like the digits from the free or center points P of contiguous figures. In the example shown, each figure M has three digits; and each digit L, L' and L2 and each connecting portion C is composed of the same number of chain Divided and this'application May 6,

In Germany October stitches. This uniformity is, however, not necessarily essential to my invention since variations are possible within the scope of the appended claims both With regard to the number of stitches in individual digits and in the connections, as well as with regard to the number of digits in each gure.

In forming the edging, the initial stitch 'I l0 of the rst digit L of a figure M is formed through ceeding free chain stitches H I, H2, H3 and H4 are made beyond the fabric edge E, stitch H5 formed through the same the'fabric, with resultant completion of said first digit. The second and third digits L and L2 are formed in the initial is formed through the point P and succeeded by four free stitches H8, H9, |20 and |2| beyond the fabric edge E. The anal stitch |22 of the connecting portion C, instead of being run through the point P, however, is passed through a point P further along the fabric edge for the start of a succeeding design figure. Repetitions of this cycle obviously result in the formation of the edging along the entire edge of the fabric.

The fabric of Fig. I can be produced With a sewing machine having, as shown in Figs. II-I and IV, a needle 1 which is operated from above a Work support I6 and carries the thread T, and a looper S6 which cooperates with the needle below the work support in forming the chain stitches and carries the thread The needle T. 1 is guided up and down movement in an and over which the digit loops L, L and L2 are formed as conventionally shown in Fig. III. The feed dog of the machine indicated at 31 in Fig. IV

Assuming the vvfabric F to be =stationary, and

the needle .1 inthe position 1a in Fig.` III whichA is determined by the step 23a of the` cam 25, see Fig. III. In making its first reciprocation, the needle 1 passes through the fabric F imrnedi` ately inward of the edge E, and, as a consequence of lits coaction with the looper B6, the

; '-jshift .of the fabric F as stitch IIB is formed. As the cam 25 rotates in the direction of the arrow in Fig. III, the needle is moved laterally to the position 1b by the step 23h of said cam, and in making its succeeding reciprocation passes down through the interval between the fingers 83, B4 beyond the edge of the fabric, With the result that the stitch H0 is completed over the finger 83 and a new stitch lll is formed. As the cam 25 rotates further, the needle is brought to the position 1c by the step 23C and reciprocated in the interval between the fingers 84, 85 With completion of the stitch IH over the finger 84 and the formation of another new stitch H2. Upon further movement of the cam 25, the needle is brought to the position 1d by the step 23d and is reciprocated beyond the finger S5 with attendant completion of the stitch H2 over said finger` and the formation of another new stitch HS. During the completion of the instant rotation of the cam 25, the direction of lateral needle shifting is reversed as the roller 22 successively passes through the step 23e (which A corresponds to step 23C) and the step 23j (which corresponds to step 23D) and finally re-enters the step 23a, with attendant positioning of the needle successively in the positions 1c, 1b and 1a and formation of the stitches H3, H4 and H5 over the fingers 85, 84 and 83. In this excursion or the needle, the rst loop L of six chain stitches is formed, whereof the initial and last stitches ll'and H5 pass through the fabric at the same point P. By two more needle excursions in precisely the same manner, with the fabric F still stationary, he second and third loops L and L2 are formed. with the initial and last stitches ofv each likewise passing through the fabric at the same point as the first and last stitches of the first loep L. Due to the coinplemental curving of the stitch fingers 83-8'5 and taking up on the needle and looper threads T, T' incident to stitch formation, the chain stitch loops L, L and L2 are caused to shift toward the edge of the fabric as shown in Fig. III, but are detained by the reversely curved ends of the fingers 84, 85. As a consequence of this control, it will be seen P. at which the fabric is Cil yadjusted as to determine that the individuality of the loops L-L'a is maintained. During the next rotation of the cam 25 after completion of the three loops L-IF, a chain C of siX stitches Il1, H8, H9, |20, I2I and |22 is produced. However, just before the formation of the last stitch |22 of this chain C, the fabric 4,F is shifted by thefeed dog 31, so that the 'said ylast'` stitch"l22 is caused to penetrate thel fabric at a point u'rther'along the edge of, the latter, with the intermediate loops of the chain entirely free of the fabric edge. By the just explained, the loops I r-IP are pulled 01T and away from the stitch fingers 83-85. Upon release, the fiat loops L-L2 `constituting the unit figure M of the ornamentation take radial positions relative to the point penetrated by the needle, and thus create the Sunburst effect.

The throw of the feed dog 31 is preferably so breaking of each chain C at the middle with its two segments extending radially to the centers of the two adjacent figures M which it connects.

The modified type of my improved edge ornamentation shown in Fig. II is like the first described, except for being formed from a single thread. The modified edging can be produced with the machine above described by use of a spreader instead of a looper in connection with means in a manner which Will be readily understood by those skilled in the sewing art.

Having thus described my invention, I claim:

l. The method of ornamenting the edge of a piece of fabric which comprises the provision of a plurality of loops in chain stitch formation, said loops projecting outwardly from the fabric edge with the inner ends of the loops penetrating the fabric at substantially a single point, continuing the chain stitch formation from the lastformed loop along the edge vof the fabric-to the first loop of a like plurality of loops in 'substantially spaced relation to the rst plurality, and continuing the cycle along the edge of the fabric.

2. The method of ornamenting the edge of a piece of fabric which comprises the formation of a group of successive independent loops in chain stitch formation radiating laterally from the edge of the fabric, the inner ends of said loops penetrating the fabric at substantially a single point,

continuing the chain stitch formation from said point in the provision of an elongated stitch chain free of the fabric, penetrating the fabric at a second point spaced from the rst point and then continuing the chain stitch formation in the provision of the first loop of a like plurality of outwardly diverging loops.
