Be it known'that I, JOSEPH A. GRoEBLI, a citizen of the-United States, and a resident and'State of New York, haver iiivented aV certain new and useful Bead-SewingMachine, of which the followingis a specificationi 'i y invention-relates to anew sewing maf i chine'j adapted to attach small'art-icles such Strung i "thread was wound spirally aroundthe beads tachment and in this as beads to .a fabric; ing beads to fabric, thebeads were first l`upon a thread and then a second and first thread, the purpose of the second thread being to space the beads apart. This simply prepared the string of vbeads for atcondition the string of eads was used in connection withfa zigzag sewing machine which. latter secured the string to a fabric by forming stitches over the bead threads. i There were' othermethods employed but I cite this as it is'thebest i method used up to the time of my present inuch inferior under my invention. 'The fabric supplied with a beaded'decoration in this manner was itself tothe product made possible invention, because `the beads were i' not very regularly v,spaced apart and owing effect.

The object of my present uinvention is to v"construct a machine which `will produce a more artistic and'v n pleasi 'product' reduce and, simp1ify theV 'ng operatlon, and increase speedofmanufacturing as well as redue the cost thereof I accom, l

tached to t-he fabric on which they are originally strung,- thereby the second as well as the separate sewing thread. At the same time Il make it possible to. manufacture a. product of better appearance. I accomplish this by spacing the beads lon their original thread, as they are att-ached by the inthe full embodiment of my invention I not only space the beads, but vI do so in such a way that the stitching mechanism of the machine will form a lstitch `between each bead, and a succeeding beadof `the very thread on which the beads are strung. This eliminates tw'o of the threads heretofore used. Furthermore, asl Athe stitches are formed of the thread on which the beads are strung, and between the bea-ds, the latter are properly and regularlyspaced apart, and

they are caused to lie 1n -a very pleasing manner upon the .fabric 'to` give thev most brilliant `and desirable effect. There is' no possibility of a.' thread coming over thesurthe bead. I preferably employ a nection with the stitching-mechanism so that the beads stitching operation upon and I have shown in the present example of my invention, this separating device arranged, wherev the looper of the stitching mechanism willL coperate with the'separator, to feed the beads'. y

The Inovement is imparted to the needle shaft from the main shaft 5, through a pin 24, on al disk 25, which pin is connected by a link 26, with a pin 27, on the needle shaft. The

The needle 28, or more correctly, -in the present illustration the hook is secured to the needle shaft in any desired way, as by screw thread- The particular manner of attaching the needle to the needle shaft can be varied, and it is Well understood in the art. The needle itself is here shown as having a hook 29, on its upper end for engaging the thread, and it travels through a nipple 3(7), attached to the under side of the work support.

On the main shaft 5, I have shown an eccentric 31, operating upon a st-rap 32, to reciprocate av rod 33, and the latter 'in turn rocks a bellv crank lever 34, which is shown mounted onalstudf. To one arm of this bell crank lever 'is fulrilmed a rod 36, which operates the looperl" :The-looper is arranged to oscillate inside a casing 37, which' l.forms a bearing therefor and this casing isarranged to hold the looper above Athe needle.

The looper is provided With a collar 43, which is `secured thereto above the casing, and with an integral collar 44, nearl the bottom which collars secure the looper in '80 its casing, but allows the looper tov revolve lThe looper itself may be variously formed, but I prefer to use the simplest construction and I have therefore shown a sim- .ple'tube 45, Vextending oif the center line of '85 the looper body and runningfrom the -bottom of the latter."

A It'vvill be observed thatthere is a plate 49, Which isA prefto be secured preferably to the casing 37 by means of 4' a f bracket 50, -Which'is secured to the plate 49, i by the screws 51, and which is itself secured to the casing by means ofscrews 52. On

the-under sideof the plate 49, I have pro- 110 vided a t'ongue 53, which inclines downwardly from the point 54, Where itlis attached to the plate 49,'to its end 55. The n l and is provided with an aperture 56, for the free passage of the '-needle therein. The tongue 53, is generally circular in. its outer contour, Which is. the active part, andatone partit projects laterally beyond the plate 49, and then'- gradually re- 12o cedes4 Within the outer line 'ofthe plate 49, incliningr downwardlyffrom` that part Where it extends beyond the. plate '49. The edge 57,

The beads 48a, on the thread trein-rather loose Jformation, and., the v'thread may be drawn more or less through the beads,

while the beads may be moved relative to their position shown to whichthread, and separated apart on their thread. Let it be assumed that the looper isin the it is'brought `when the rod 36, is inl the'left hand position in will lie through thelooper body,

` At about Qthe same time the looper will be reversed in" its cuts in .between the lowermost bead and the one above it.- HWhen the lowermost bead is carried around far ,enough sothat the thread -1s engaged V'by the plate49, and not by the tongue the lowermost bead will lose the sup- 'port of the tongue, p the edge ofthe plate, it will therefore drop down the thread and against the fabric -near the stitch just formed by the needle. lfThe bead which was next to the one thus spaced will be held up by the -edge ofthe plate 49. We now have a stitohformed o-f the thread,

The fabric will now be fed forward in wel] fknown ma; ner by a suit-able feeding device. The? needle will nowibefagain advanced through the fabric and the looper will be rotated as needle.

This second stitchwill formed in the thread beyondthe. bead which was separated in the previous operation, so

As it does so the bead which dropped tothe tongue will ride downl thereon, and finally dropdown to the fabric, leaving the Ones above it held up by the plate 49.
