Specification. of Letters Patent.

Patented Mar. 26, 1918.

Application filed October 15, 1914. SerialNo. 866,783.

To all whom it may concern:

Be it known that I, ARTHUR L. Gunmen, a citizen of theUnited States, and resident of Newton Highlands, county of Middlesex, State of Massachusetts, have invented an Improvement in Button-Cards and Independent Lock-Stitches Therefor, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

My present invention is a lock stitch made by employing a plurality of loops and resulting in the formation of a locked stitch having three strands of thread in holding engagement. novel double loop-stitch formation is particularly useful in attaching buttons to clothing, or to button cards, or the like, as each button is held by an individually locked stitch, and by means of a plurality of thread parts, each comprising a portion of the double loop-stitch. An important advantage of this feature, wherein a plurality of thread parts engage the button, is that the button is held firmly and squarely on the article to which it may be attached, whereas a single thread part necessarily gives more play, or looseness in the attachment than is desirable. With three strands of thread, however, engaging the button and with these thread parts all looked, a very strong, secure and satisfactory stitch is made. In the particular line of work of carding buttons, it is important, for many uses, that such buttons be attached by thread, instead of by wire as shown, for example, in my prior Patent 1,055,523. Prior to the invention of my loop-stitch shown in copending application Serial No. 824,907, filed March 16, 1914, it has been necessa to card buttons, when thread was employs by hand, but this has of course been very slow, expensive and unsatisfactory. The present invention is especially valuable in carding buttons with thread and by means of my novel machine, wherein a single continuous line of thread is employed, and the double loop stitches of the present invention are made therefrom. A further feature of the present double loop-stitch is that it may be formed successively in lines of indefinite length, and at the completion of each stitch the thread severed, leaving both ends of each stitch locked in the double loops of said stitch. This is especially advantageous in attaching buttons, as any number of successive buttons may be secured, each individual button. being independently attached with both ends of the attaching thread locked. Furthermore in button carding, it is often desirable to remove a single button in order to replace it by another which will match better in color and shade with the rest of the buttons on the card, and my present stitch enables such removal and replacement to be made without disturbing the other buttons or their attaching stitches. And, while one button may thus be severed, all the buttons may also be severed by one sweep of the knife when desired, or an entire row may be out off. In the drawings I have illustrated the stitch as applied to a button card,

Figure 1 being a view of a card with a plurality of buttons attached thereto by means of my novel double loop stitch;

Fig. 2 is an enlarged view showing a button and the adjacent part of the card in cross section with the threads forming the double loop-stitch loosely shown for the sake of a clear disclosure;

Fig. 3 is a view similar to Fig. 2 with the threads drawn tight; and

Fig. 4. is an enlarged view of the under side of the button card showing both ends of the thread locked in the double loops respectively engaging the same.

Buttons are usually carded in groups of a dozen, being attached in successive rows, the

card 1 herein illustrated having a series of rows of buttons 2, each attached by my double loop-stitch passing through opposite eyes 3 and 4 in each button. The double loop-stitch is made from a single thread on my carding machine illustrated in copending application Serial No. 72,054 filed Jan. 14, 1916, and is made quickly and automatically. The completed stitch comprises the double loops 5 and 6 passing through the button eyes 3 and 4 respectively, the loop 6 catching and binding a single part 7 of the thread which is passed through the opposite eye 3 and the loop 5 encircling and catching the free end 8 of the thread which is passed through the eye 4, the completed stitch comprising the free end portions 7 and 8 and the intermediate connecting loop portion 9. All three parts 7 8, and 9 engage the button and pass through the eyes 3 and 4;,

constituting three thicknesses or parts of the thread to hold the button on the card 1. In forming this double loop-stitch from a single thread, the free end 7 is passed clownwardly through the eye 3 and caught while the needle is withdrawn and moved (or the button and card are moved) to next go through the eye l, leaving a loop of thread 6 caught on the under side of the card 1, the needle then being withdrawn and again moved downwardly through the eye 3 where the loop 5 is formed and caught preferably by automatic mechanism as explained in my said machine application. The needle is once more moved through the eye at where the thread is cut as the needle is withdrawn, leaving the free end 8, the thread being at all times carried while through the eye of the needle. The loop ends 7 and 8 of the thread are drawn through the loops 6 and 5 respectively, 2'. 0., the loops extending through the eyes opposite to the eyes through which the free ends respectively pass, and the entire stitch is drawn tight, locking both the loops 5 and (3 and the free ends 7 and 8. ll prefer to draw the first free end 7 through the loop (3 as soon as that loop is formed, and while the needle is in the operation of forming the second loop 5, thus drawing the end 7 and loop 6 into locked or knotted engagement before the completion of the stitch. i also provide mechanism to hold the loop 5 and receive the final end of the thread, drawing the same through said loop as the final operation in forming the stitch. This process of formation of my double loopstitch is not herein claimed specifically, nor is the mechanism which forms it, the presand claiming the ent application describing completed seam of double loop-stitches. This stitch may be employed to hold any two or more articles together, or to attach buttons, or for other purposes, as will readily occur to those skilled in the art. I believe that a double loop-stitch having each free end locked by one of the loops of the stitch, and also having a plurality of three or more thread parts uniting two articles together securing the stitch incident to such multiplicity of parts, to be distinct novelties in this art, and I therefore wish to claim the same broadly. Fin'thermore, the use of such a scam in the art of button cardingto which the invention primarily directed-is of distinct commercial advantage. One advantage is that in stripping buttons from a card it is desirable not to leave any loose thread ends or dangling buttons, and the present invention accomplishes this by having each button secured separately from the rest and each stitch firm and complete in itself, not dependent for its firmness upon Enrica at this patent may be obtained for any other stitch, as all the stitches are entirely separate and unconnected, so far as their holding power is concerned, While nevertheless a row of stitches can be made by a continuous thread.

Having described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A seam for sewed articles, comprising a plurality of articles secured together by a double loop stitch having a plurality of looped thread portions passing through the articles to be united, at least three thread parts being in engagement with the articles about which the loop is made, and each loop being locked by an end portion of the thread passing therethrough.

2. A seam for sewed articles, comprising a plurality of articles secured together by successive independent stitches, each stitch comprising two thread loops spaced apart, each loop being adjacent an end portion of the thread forming said stitch, and with said end portions being locked under its adjacent thread loop.

3. A button card, comprising a card of sheet material, a plurality of buttons secured on one side thereof by a corresponding plurality of independent stitches passing through the buttons and the card, each stitch comprising a plurality of looped thread por tions formed to lock its button firmly onto the card and irrespective of aid from the stitches or thread of adjacent button-holding means.

4. A button card, comprising a card of sheet material, a plurality of buttons secured on one side thereof by a seam consisting in successive stitches, each stitch having a plurality of looped thread portions passing through both card and button, the loops of each stitch being spaced apart and with each of the ends of the thread of each stitch being locked by a loop of said stitch.

5. A button card, comprising a card of sheet material, a complement of buttons, each button having a plurality of perform tions and being secured to one side of the card by stitching passing through at least two of the button perforations, each stitch being formed of a plurality of thread loops and engaging said button by a plurality of thread parts, said stitch being inde aendent in its button-holding action from other devices or adjacent stitches on the card.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses. 1
