BEAD-SF- Wnof MACHINE. s

ladap'ted to attach' any Vsmall articles such as beads' which are vstrin'ig yupon a thread. to a fabric, by means of `stitches formed with the thread on Whichvthe articles are strung. ln the following description and claims l'use the term beadsin the broad sense to cover any formof article which may be vstrung on a thread.

Inpl.V S. Patent VNo. 1,041,780 dated October 22, 1912, l showed andV describeda machineV for attaching beads or similar articles to fabric by formingjstit'ches in the fabric with the thread on which the beads are strung. That machine is .adapted to attach the beads Without the .useV of separating threads Wound spirally aroundV the V:beadsv and original thread and Without the use'of a separate or stitching thread in addition to the one on which the beads are originally strung.Y In U. S. Patent No. 1,073,344 dated September 16,11913,I showed and described a machine of asimiliarv nature. but With the additional advantage that the beads 'could be attached not only in a straight line' but in any desired formation.

VThe present invention isiadapted for the samel general purposes asV ther machinesl of my said prior patents. In thepresent machine l have provided additional features which insure the regular and unfailing. feedingof the beads and their advancement-to the point of theirattachment tothe fabric.

One branch of my invention relates to the means for `primarily, holding back the beads from the source of supply'and for allowing them to advance singly'towardthe stitching mechanism. This branchl'of my invention is intended to provide a simpl'e'and eflicient automatic device for feeding or separatingv the beads as they first leave the' source of supply in order that the operator will not be obliged to Igive any attention to' thefeeding of the beads Where the stringof beads moves into the'vertical position, during the operation of the stitching mechanism. This preliminary feeding or separating device is' `PatentNo. 1,073,344,

preferable in order that the Whole supply of beads shall not rest upon or collect in too great numbers near the final separating 'device and the stitching mechanism. This'preliminary feeding-or separating device not onlyV regulates or "controls the separation of the beads Yas they leave the source'of supply Y but it also assists in the: feeding or advancement of the beads as they areseparated. A

The final separating' rdevice is not` only adapted to separate the beads on their thread as they approach the stitching position but it is intended to positively move the beadsv down to the'pint of attachment-to the .fab-

ric, so that the beads Will not be .heldb'ack by any friction on the' thread but each one ivill beA advanced to'fin'al position in proper' time in relation'to the stitching o'perations u Thisbranchof the invention is disposed tol operate on the beads between the final sepa-v rating device (if more thanoneseparating.

device is used) kand the fabric `and it is preferably so constructed that the action of the thread loo-per vvill cooperate? tofeed the-` beads to the fabric.

Another feature of improvement relates to the lfilial bead 'separator' and this is' intended to rprevent the beads frompas's'ing the separator except as intended, even -if-the thread should'become momentarily slack.

1,073,344 and in so-pfai" as the rparts in the present case correspond .with vthose of said' primary sepais an elevation yof the principal' v patent they are similarly numbered. Tn-

asmuch as the present invention may be applied to a machine like that of said` Y such parts as may be necessary to the proper understandingV of thev additional or substituted features. Y i

Asis set forth in my said Patent No. 1,041,780 the machine Vis intended to attach strung articles, such as beads, to a fabric by stitches, and as set forth in my PatentNo. 1,073,344 the machine may be employed to attach the articles either in straight lines or in any other formation. V

In the present case VI have shown an upright rod 98 near the right hand end of the machinev and supported from `,the frame thereof. This rod forms a support'for a bracket 99 which isradjustable thereon; and forV a second bracket 100 which is also adjustable thereon. The bracket 99 carries the forks 101 provided with anY arbor 102 on which the reel 103 with the supply of thread and beadsis adapted to revolve. A friction shoe 104'Y is pressed against the reel 103 to vput a slight tension thereon to prevent the reel from turning yfaster than required to let ofi" the string of beads. The beads 26 are yloosely strung on a thread 26""L and the strung beads on the reel 103 are intended to furnish Vthe supply necessary for the operation of the machine. Y

The bracket 100 forms one of thefsupports (the upper one) for a trough 105 which guides the beads fromthe reel 103 to a point Vover the stitching mechanism. There is a bracket 106 fixed to the machine frame near the left hand end, andat its top there is arranged a stationary arm 107 which -forms one of the supports for the trough. n

The trough 105 is intended to form a guide and support for the beads. It has upright side walls 108 spacedsuiiiciently to receive the largest beads likely to be used, and

it `has a V.shaped bottom 109 which will cause the string of beads to center in, the trough so that they will approach the primary separating device in Vregular order, i. e., in a row. Y

The device for primarily separating the beads upon theirl thread consists of the following: Y

The bracket 106 has a bearing for a shaft 110 and the latter has an arm V111 fixed thereto andeXtending outwardly. A link 112 is fulcrumed to the arm 111 at one end and at its other end it is fulcrumed to anarm 6() whichl is an extension of the lever arm of theV lever 60-62 of my *saidV Patent fNo.V 1,073,344.v As this lever is operated periodically Vby the cam 48 on the main shaft 3, the

arm 60 operates the link 112 and thus rocks the shaft 110 intime with the stitching operations of thevrnachine. It is to be understood that the arm 60 in the present case' is used to move thev shaft 110 in'addition to the function which it performs in'my said patent. Y

There are fixed on the shaft 110 twO, plates 113 and 114 one lying in advance of the other a distance equal to the length of an individual bead. The inner edges 115 of these plates break joint or are arranged in overlapping planes and each plate has an arcuate slot 116 curved concentrically with the shaft 110. These slots extend from the edges 115 of the plates andeach is wideV enough to allow the bead thread to passk Y position, viewing the parts in plan, then the bead thread will extend from the trough 105 'j through slot 116 in the plate 114 and the lowermost bead will rest vagainst the Yplate 114 (the remaining Vbeads `resting against this lower one) and the inneredge 115 of Y the plate 113 will `be in line with the rear end of the lowermost bead. If the shaft 1104 is now rocked toimove the plates 113, 114 to Y the right, the plate 113, will cutkin between thevlowermost bead (the one just heldback by the plate 114) andthe bead just behind it. The beads in the trough will now be held back by the plate 113 instead of the plate 114, and when the latter moves toward the righty hand position it will have cleared the lowermost bead. Y The latter being no longer held back, will move down on the thread. Upon the reverse motionA of the shaft and plates, 113, 114 (toward the Vleft when viewed. as in Fig. 3)- then the plate 114 will again straddlethe thread and come into the path of the beads; andthe plate113' will withdraw from ,the path of the beads, allowing them to move down against the plate 114. Each time the plates 113, 114 make a complete movement to the right and left .a bead israllowed to pass intheV manner described, but only one'eanV pass as the others are held back. If two or more beads are to be fed at each operation it is only necessary to separate the plates 113, 114 so that the one lies behind the other the length of two or more beads The bead thread leads, from the upper separator to a novel guidingdevice which permits the thread to change to a vertical or nearly vertical direction. On the bracketV 10G there is' iiiied an arm 117 which extends around the separating device andfwhich has its free end 118 extending-at right angle to the bead thread. There is anA idler 119 mounted on the end 118 and adapted to beturned freely, by the beadthread; rIfhis idler has transverse groovesv 120 which may be spaced to correspond substantially withtheA length of a beadY and it has a peripheral groove 121 in which the thread may lie.

As the threadtravels 'around the'idler 119;.

' thread and throughtheshaft STtowardthe stitching mechanism.

rlhe lower separator which. is associated directly with the stitching mechanism may. beoperated in a similar manner to the separator in said Patent No.'1,073,344. There is an annular ring 69 which is supported from the'bracket 69a and this ringv formsa bearing for the separatorlplate 73. The lat-- ter includes` an annular ring portion` 66 which Ahas gear teeth 67 on its upper surface and the gear 90 on the shaft 89 is adapted to act on these teeth for the purposeof revolving the separator pla-tete corespond with the changes in the direction offfeedfof the fabrieand the changes in the direction of stitching. The gear 90 may be connected to and operated bythe same actuating devices as those shownv in my said later patent to operate the presentv separator in a similar manner and for the same purpose that the separatori-is operated in my said`v later patent. Y The separator inaddition to the ring- 66 has an inwardlyV extending neck 'T2 which carries the inner. plate 73. The latter has a central. aperture 73a `into which the sewing needle or hook 10 may pass. The outer edge 122 ofthe plate 73 is circular for the greater portion of itscircumference, preferably con- Ycentric with :the path ofthe needle, and itv Y extends inwardly at 12? from the circular portion. separating a beadbetween successive stitches comprises a plate 124 secured to the plate 73 and below the upper circular edge-122 of-fthe latter. The distance ofthe plate12t below that of the edge 122 corresponds with the length of a singlef bead Viflone bead is to be fed after each` stitch, or,' if two or more beads are .to be fedvafter each stitch then the plate 124 will be lowered accordingly. This plate 124 lies under the-.cut away portion 123 ofthe plate 73 and it is. slotted at 125 to provide the supporting portion 125^and an outer supporting portion 126.

The under side ofthel plateTS, Iis provided with means for advancing the beadsdown along-their. thread and ,itis` arranged to act*v on the beads between the separator` andfthe.

ispreferably'the sameasthat shown in my saidv Patent No. 1,()731t` Vand it may .be4 operated by the same mechanism and: for more detailed description thereof reference may be had to said patent.

The sewingvneedle or hook 10 shownhere-y iii-may be operated the same manner asin-my said laterA patent and in sofar as the operating parts are sho-wnlh'erein they-are lettered'` the same .as-insaid patent.

I have previously setforth the. operation of .the primary feeding and separating device and I will here .set-forth the` operation of those parts which finally separate and feed the beads.V l l TheV looper body 23V is o'scillated by the complete revolution and-,the looper oscillations are controlled according to the change in the direction offeeding of the fabric, by

revolving the shaft 28 in the manner set forth in my said later patent. understood that the'worm 271opera'tes ona Worm 22-on the looper body23 the same as been made in, the fabric, each complete op` eration of'the'machine may be traced as follows: The beads, generally at Aleast. several in number, which have been fedto the vertical run of: the threaddrop down so that the lowermostbead rests on the plate "73 lor the plate V124 andi several others rest ldown'on the lowermostbead. If the delivery end 'of' thelooper25- is near the inner end of the. slot 125y in the plate 124the beads will rest on this plate, the thread leadingV from the yend of the looperthrough the slot 125' and to the point 0f the last, stitch in the- At about this moment* or immedi-l fabric.l ately after,the .sewingfhoolr 10 is Lmoved upwardly through the fabric 'and intoA the aperture 73a.

Si i

A Vworm 27'which reciprocates with thesha-'ft- 28., so that it makes somewhat less than a;

loop the thread around the sewing hook 10. The latter will then be withdrawn downwardly through and out of the fabric, forming a switch. On the return oscillation ofv the looper theV thread will be carried around the circular edge 122, countercloclrwise, from the point 132 to the point 131 within the slot 125. When the first or clockwise movement of the looper takes place, the lowermostbead is resting on the plate 124 and when the thread commences to rest against the circular edge 122 of the plate 73V this edge cuts in between the lowermost bead and the one next above it and as the lowermost bead slides off the plate 1211 it is no longer Vsupported and it isfree to travel down the thread to the fabric below.` Thesucceeding beads, however, are supported on the edge 122 of the Vplate 73 while the looper is completing its oscillation back and forth around this plate. A's soon as the lowermost bead referred to has been cut off or separatedrby vthe'edge 122 it may slide down the thread asV above set forth, but if it should not drop immediately of its own weight'it will be engaged by the cam edge 128 and as the looper carries the thread around the edge 122 the edge 128, acting somewhat like a cam, will force the separated bead down the thread so that it arrives at its pointl of attachment to the fabric by the time the looper carriesthel thread to the point 132. This insures the positive feed of the bead to rits point of attachment at the proper time.

In theA embodiment of my invention shown herein no action to feed the bead downwardly is required other than `the action of the looper in castingz the loop around the sewing hook and the cooperation of the cam edge 12S; so that thevdevice is not complicated by cumbersome mechanism.

Vhen the looper makes its return'movement from the point 132 to the' point 131 the beads above the separator will first rest on t the edge 122 of the plate 73 and then they will drop one bead length and besupported by the plate 12a until the commencement of another operation of the looper. At each complete oscillation of the looper the above described operations will be repeated. After each stitchthere Awillbe a bead fed down the thread to the fabric so that each bead will lie between successive stitches, thefsamev be a slight thrust of thebeads as the looper reaches the slot 125 the beads will not be cast off the support 73 and travel down' the thread other than as intended.

vExcept as herein set forth theinachine as a whole may be constructed and operated as set forth in mysaid patents. i
