2 Claims.

My invention relates to stitch sewing and relates particularly to making a spaced cross stitch by machine, simulating a hand made cross stitch.

It is, therefore, an object of my invention 'to provide a method for making spacedcross stitches on a quantity basis.

It isanother object of my invention to provide a simple method for manufacturing spaced cross stitches by machines which are readily available.

.Qther objects of my invention are to provide an improved method of forming cross stitches which is economical in quantity production and which meth'od'is relatively simple.

With the above and related objects in view, my invention consists in the details of construction and combination of parts as will be hereinafter more fully described and which will be more readily understood when the description is read in conjunction with the accompanying drawings in which:

Fig. 1 is a plan view of the back of fabric showing the formation of the back of the cross stitching; a chain of loops on the left hand side and a series of threads on the right hand side. The

formation of threads on the right hand side is slightly exaggerated and out of position so that V the steps of the process will be more readily understood.

Fig. 2 shows the front face or the bottom of the Fig. 8 is a view of the back of the fabric, both the threaded needle and hook needle being omitted, showing the position of the loop which has been drawn through the fabric and which loop by the oscillation of the needles from the position indicated as in plane 3-3, has been moved forward, also thread T has been moved backward.

Fig. 9 shows the back of the completed cross stitch; The steps of the process have been repeated so that the threaded needle and the hook needle in unison have pierced the fabric; the looper has come into operationdrawing the extended thread and looping it around the hook needle; the newly formed loop has been drawn through the previously formed loop thereby completing the cross stitch. I Fig. 10 is a schematic View showing the continuityof the thread. 1

fabric wherein a series of cross stitches have been completed. I

Fig. 3 is a fragmentary view showing the threaded needle and hook needle, both needles have pierced the fabric and they are in the position indicated by the lines 3-4 of Fig. 1.-

Fig. 4 is a fragmentary view showing the threaded needle, the thread, and the hook needle, with the looper moving into position to grasp I the extended portion of thethread.

Fig. *5 is a View showing the next step in the V series of operations wherein the looper has carried the extended portion of the thread and looped it around the hook needle.

Fig. 6 shows the relative position of. the

threaded needle and the hook needle after the threaded needle and hook needle have moved in unison in an upwardly direction, the hook needle drawing the loop through the fabric thereby forming one portion of the first cross stitchon the face'of the fabric.

Fig. 7 is a fragmentary view showing the previously formed loop encircling the hook needle,

and both the threaded needle and the hook needle piercing the fabric.

Fig. 11 is a modification of the type of cross stitch that may be made with my "invention.

Referring now in detail to my invention and the steps of the method involved in making my series of cross stitches, each cross stitch being generally designated as X, wherein each cross stitch is spaced from one another on the fabric,

and the cross stitches resemble hand made cross stitches although made by a machine.

My invention is carried out with the use of a sewing machine (not shown) having a threaded needle l0 and a hook needle l2 which are spaced apart in one needle bar (not shown), and the needles bein rigidly held to move together in a vertical reciprocating direction, and both threaded needle l0 andhook needle l2 also may oscillate 0 together in a horizontal plane.

Throughout this specification both the threaded needle l0 and the hook needle I2 simultaneously move as a unit vertically, and oscillate horizontally since they are rigidly held in the same needle bar. Hence, reference to a vertical movement of one needle means that the other needle moves likewise in the same direction, and reference to the oscillation of one needle in a horizontal plane in one direction means that the other needle oscillates in the opposite direction in the same plane.

The movements of the threaded needle l0 and the hook needle l2 are predetermined and move in a cycle of events which are repeated for each successive cross stitch. Hence, a suitable camaction may be embodied in the sewing machine (not shown), to repeat the series of steps embodied in my process.

A piece of fabric, generally designated as F, is placed so its face II- is down on the bed of the sewing machine, and the back of the fabric is up. The fabric F is held face downwardly and it is advanced by a suitable work advancing feed (not shown). The threaded needle It carries a thread, generally designated as T, which thread forms the cross stitch on the fabric F. The thread T supplied from a cone or spool (not shown) is fed down from between the needles and is threaded through needle 10 from the same direction.

As Fig. l is viewedboth thethreaded needle l and the hook needle [2 simultaneously pierce the fabric F along the plane 33, which view is represented in Fig. 3, both needles reach their lowest position, and start upwardly, and a looper, generally designated as L, see Fig. 4, suitably timed, carries the extended portion of the thread T to loop it around the hook needle I2, see Fig. 5. Hook [2A of the hook needle [2 holds and draws the loop upwardly simultaneously with threaded needle I0 carrying a new portion of thread-T supplied from a cone or spool (not shown). The

threaded needle l0 and hook needle I2 are elecated as shown in Fig. 6 thereby forming one face portion XI of the cross stitch X. Both the threaded needle l0 and hook needle I 2 are oscillated horizontally counterclockwise to the desired angle of crossing which generally would approximate 90, so that loop Li, held in hook |2A of hook needle I2, is carried forward; simultaneously thread T is carried backward and is shown as short thread Tl, see Fig. 1. Loop Li Y is shown as the first link in the chain of stitches appearing in Fig. 1; In the new position aforementioned the point and hook of the hook needle 12 as well as the threaded needle i0, pierce the fabric as before and the looper L moving in position to grasp the newly extended portion of thread T, loops it around the hook needle l2 as before, which needle is encircled on the back of the fab.- ric by the aforementioned loop Ll, see Fig. '7.

' The newly formed loop L2 is pulled through the fabric and the previously formed loop Ll to form a stitch-the second portion X2 of the cross stitch X is formed, thus completing cross stitch X on the face ll of the fabric.

The movement of the fabric F by the work advancing feed (not shown) a suitable distance carries the fabric backwardly, thus bringing a new section of the fabric in position for a new cross stitch. p

Simultaneously with the movement of the fabric F by the work advancing feed (not shown), both the threaded needle and the hook needle l2 are oscillated horizontally clockwise; the

movement of the fabric F carries the loop L2 for ward although the hook needle oscillates backward; simultaneously thread T is carried forward and is shown as long thread T2, seenFig. 1.-

The loop L2 above the fabric F becomes the feed space loop connecting the completed cross stitch X with the cross stitch that is to follow. Another link in the chain of stitches, see Fig. 1

Both the needles l0 and I: again are oscilangle or; degree of crossing which approximates lated horizontally counterclockwise to thedesired designated as thread T3, see Fig. 1, and then.

the other side, the drawing Fig. 1 shows the right hand line of thread T somewhat zig-zag but this is exaggerated, for cross stitches shown in Fig. 2, as the line is nearly straight on the fabric, the stitches being almost superimposed one on the other. However, on the face of the fabric a series of equally spaced attractive crossstitches, simulating hand embroidered cross stitches is formed.

The cross stitch may form an X-like cross stitch, as cross stitch X in Fig. 2, or a type cross stitch, as cross stitch A in Fig. 11, or a cross stitch in any position from X to +,wherein the cross stitches are spaced from ,one another.

The plus stitch A of Fig. 11 is made by the same action as the X stitch of Fig. 2 except that the needles are shifted to an angle of approximately 45 when the stitch is started.

My invention may be employed to hold two separated pieces of fabric together or it, may be used for ornamental purposes.

Although my invention has been describedin considerable detail, such description is intended as illustrative rather than limiting, since the invention may be variously embodied, and the scope of the invention is to be determined'as claimed.

I claim as my invention:

1. A method for making across stitch by machine simulating a hand made cross stitch comprising the steps of moving a threaded needle and a hook needle in unison through a fabric,

looping a portion of thread from the threaded needle around the hook needle, withdrawing both of said needles, whereby the hook needle draws said loop upwardly. through the fabric, oscillating' said needles in unison, said loop remaining on said hook needle, and dropping both of saidneedles through said fabric, forming a new loop on said hook, beneath said fabric, and withdrawing said new loop through said first mentioned loop to complete said cross stitch.

2. A method for making a cross stitch by machine simulating a hand made cross stitch comprising the steps of moving a threaded needle and a hook needle in unison through a fabric, looping a portion of thread from the threaded needle around the hook needle, withdrawing both of said needles through said fabric, oscillating said needles in unison, moving both of said needles in unison through said fabric, forming a new loop on said hook needle, withdrawing said new loop through said fabric and said first mentionedloop to complete said cross stitch, moving said fabric to a new position and simultaneously oscillating said needles in unison, and forming a new cross stitch as hereinbefore set forth.
