CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS NEEDLE Application filed August 23, 1929. Serial No. 388,020.

This invention which relates generally to needles for darning or embroidering is concerned particularly with certain features of construction by which such needles are rendered adaptable for producing a stitching of novel and attractive character. By way of exemplification, I have illustrated in the accompanying drawings a needle having certain improved features, Figures 1 and 2 being face and edge viewsthereof in'elevation, and Figures 3, 4 and 5 examples of single, double and cross weaving or stitching which may be performed with such a needle.

Referring now to Figures 1 and 2, the present needle A is shown in the general form of a thin flexible blade having one end suitably shaped or pointed at 6 for insertion into the work. The opposite needle end or head 7 which may be very slightly wider than elsewhere is preferably rounded, and close to this end of the needle, I provide two or more slots 88, side by side or offset, forming eyes through which to receive the darning or embroidering yarn or cotton which is to be woven or stitched into the work.

The opposite, edges of the needle are substantially parallel, and the width of the needle, as compared with others commonly in use, is considerable. The other cross sec tional dimension of the needle, that is its thickness, may be uniform, or substantially so, from end to end. Because of the unusual width of the needle it is possible to obtain from the use thereof certain interesting results, but the work or fabric which the needle is required to penetrate in performing a darning or embroidering operation should desirably have its warp and /or woof threads spaced apart a distance which corresponds generally to the width of the needle. Such -a fabric construction is suggested in Figures 3, 4 and 5 to which further reference will now be made. 1

. The fabric material to be worked with th needle of this invention permits of several variations in the weaving which is performed. By the cross marks in Figures 3, 4 and 5, I have indicated diagrammatically the juncture points of theinterwoven Warp and woof threads which togethercompose a figures of the'drawings Inserted into the I eyes 8-8ofthe needle are duplex threads at and b of yarn, cotton, or the'like, and such threadswhen worked in the fabric lie side by side,'as at a: and y. The number of eyes to be formed in the needle will be determined according to the number of threads to be handled by the needle at one time, and .con-

sequently more than twoeyes, if desired, may be employed.

In the operation of my needle with duplex threads, as above suggested, a single weaving may be performed. Such an operation is illustrated in Fig. 3 wherein it will be noted the needle is worked always in a single direction to draw the duplex threads in and out in parallel rows, the exposed portions of the darning or weaving being desirably in the form of staggered squares to provide a tessellated effect. By double weaving, as suggested in Figure 4, the fabric material is covered completely with squares of the embroidery or darning thread which are disposed transversely in alternation. A further example of possible weaving is set forth in Figure 5 wherein I have shown a cross stitch, one that is produced by working the needle and duplex threads diagonally'crosswise back and forth to provide open squares or diamonds bordered by stitching that tends to expand slightly in its middle portions which are remote from the juncture points of the woven threads forming the fabric matewhich is more readily susceptible to die or stamping operations. A needle of this fiattened character also possesses the advantages of spreading more easily the warp and/or 7 woof threads of the fabric material, and of sliding with less resistance through the spaces thereby provided. In so doing the a needle may be flexed, as required in the single direction of its thickness. Furthermore,

the substantial width of the n'eedleitends -al-' ways to facilitate its use in the same plane; that is, any twisting or turning thereof in the weaving or darning operation is automatically resisted. This is of importance where, as in the present case, duplex threads are to be worked, and the smooth, parallel, and non-twisted?disposition of such threads is a contributing factor inthe appearance of the finished product.

I claim:

A needle of the kind described, relatively fiat and flexible in one direction only, and provided adj acentone endwith transversely spaced unconnected eyes for receiving and, drawing a multiplicity oflthreads between the threads of a fabric without twisting of the drawn threads. r

In testimony'whereof, Ihave hereunto set my hand this 7th day of August, 1929. :20 LEONARD G. DAHM.
