' Threading Tape into Edgings, of which the following is aspeciication.

The principal objects of myinvention are rst, to providein a machine forinsertingtape in lace or edgings a star-wheel'the star-like projectionsv4 of which en gage each alternate bar of the laceor edging 'to-raise anddelive'r the barfupon a 'needle andrtoppermitpassing of a succeeding bar under theneedle to interlace the body of the needle into the lace v or edging as the same is advanced upon the needle; second, to actuate the star-wheel by each alternate bar of the lace or edging to permit .the proper insertion of the needle under and over the bars independent of the varying or unequal distance of the bars from.

each other, and, third, to provide in such a ymachine a groovedtape-bar adapted to receive and'hold'the tape and to be readily engaged and clampedas well as disengaged from the needle.l A n l The nature and scope of my invention will be more fully understood'froin the following description, taken in connection with the accompanying drawings, fo'rming'part hereof, in whiehr- Figure lis a'longitudin'al sectional Iview of a machine embodying main features 'of my invention.

sion-rollers for the lace or edging. Fig. 4. is

a top or plan viewof Fig. 3. Fig. 5 is an enlarged detail view illustrating a portion of the needle rand tape-bar and the tape inserted into the bar; and Fig. 6 is a side elevational view` of Fig. 5, partially sectioned, illustrating the-mode of uniting the tape-bar with the Y A needle-body and clamping the end of the tape My invention has relation to that class ofl between the said bar and body.

Referring to the drawings, inthe machine as illustrated the lace or edging ct is univound from a reel ct and passes under a guide a2 and flattening and friction rollers a3 and a4 vto stretch the lace or edging laterally and to maintain its bars a5 in a flat or straight condition before presenting the same to a table h. 'To the under face of the table b is secured a guide b', which is adapted to engage the barswa` of the edging and to guide the same to two upwardly-projecting and curved guide-fingers 'b2 and b3, between which a star-wheel C is adapted to rotate. The table bis 'furthermore provided with a springarmlii, the curvedend hof which is centrallyilocated between the guide fingers b2 and h3 and which is adapted to depress the tape a between said bars a5 of the fingers for a purpose to be presently more fully explained. The star-wheel C is loosely mount.- ed on a shaft o', secured to a standard c2 and held in frictional contact with the same by a spring c3, mounted on the shaft c, as illustrated in Figs. V3 and 4. The star-like projections cf of the star-wheel rotatebetween f the curved guide-lingers b2 and b3 and between which the curved delivery end d of the threading-needle D is located, so as to permit the free rot-ation of said wheel andits projections.

tal position by milled feed-rollers e, e', e2, e3, e4, and c5, which also engage'theedging a and y-rintheirrotation` feed the edging forward from left to right of the machine. In orderto insure lthe proper and alternate presentation of the bars a5 of the edging ot to the star-wheel C, the bars a5 in the forward travel of the lace or edging beneath the table b areu first The threading-needle D is held in a horizon- ICO asbetween the star projectionsc4 of the starwlleel C, which projections, however, are only permitted to engage the bars a5 after the same have traveled over the forward portion of the guide-fingers b2 and b3, as illustrated in Fig. 3. The free ends of the guide-fingers are depressed, permitting the star projections to project above the fingers in such manner that a forward sliding bar will first engage the straight portion ci of the notched end of the projection c4 until it is prevented from further movement thereon b v abutting against the linger c6 of the notched end. The bar a in its forward movement will now rotate the star-wheel C until the projection cV1 has delivered the bar a5 of the edging a upon the downwardly-projecting end d. ofthe needle D and until the fingers c of the projections c4 are disengaged from the bar a5 by the bar a5 sliding forward on the needle D, at which time the star-wheel C comes to a standstill. The next succeeding bar a5 of the edging, however, will not be engaged by a star projection c4 of the star-wheel C, since the distance of the projections c4 from each other is greater than the distance of the bars a5 of the edging a from each other. The succeeding bar a5, fol lowing the bar raised by the star projection e4, will slide forward over the fingers b2 and and b3, and the end b5 of the tension-arm h4 by depressing the bar a5 will conduct the same under the end d of the needle D and in this manner interlace the needle D into the lace or edging. The star-Wheel being rotated by the bar a5 of the lace or edging a, which has been deposited upon the needle D, brings another of the star projections c4 in such a position that a bar a5, following the bar fed under the needle D, will engage the projec- Lion c4 and rotate the wheel C, as herinbefore described. In other words, each alternate bar a5 of the edging a will be engaged b v a star projection c4 of the star-wheel C and placed upon the needle D. The rotation of the star-wheel C by alternate bars of the lace or edging avoids the necessity of having the bars a5 arranged a predetermined'distance apart from each other, since the proper operation of the star-wheel is made entirely independent of location and distance of the bars a5 from each other. It therefore follows that the proper interlacing of the threadingneedle D into the edging will in all instances be accomplished whether the bars a5 of the edging follow each other in regular or irregular sequence. The lace or edging delivered upon the needle D is fed over the body of the same by the milled rollers e e', e2 and e3, and e4 and e5 and onto a grooved bar l, adapted to receive the tape f to be inserted into the edging. In order to connect the grooved bar E with the needle D, the same is provided with a contracted extension d2 of such shape that when the extension is inserted into the grooved bar the sides and upper and under face of the needle-body will be in alinement with the grooved barE, as illustrated in Figs.

5 and 6. The end of the tapef is at the same time securely clamped between the extension (Z2 of the needle D and the grooved bar E by placing the tape around the edge of the grooved bar, which slides under the extension d2 and between thc same and a leaf-spring d3,

preferably integral with the needle D. The' leaf-spring d3 furthermore holds the grooved bar E in engagement with the extension cl2 of the needle D and at the same time adords means of ready connection and disconnection of the needle to and from the grooved bar E. The groove e in the bar E is of sufficient depth to prevent the contacting of the bars a5 of the lace or edging a with the tapef during the feeding of the bars aGover the grooved bar E. To maintain the body of the needle D and the grooved bar E firmly in position in the machine during interlacing of the needle into the edging and during'feeding of the same over the needle andthe grooved bar, the first two sets of milled feed-rollers e e' and e2 e3 are grooved to receive the contracted body of the needle D, whereas the last set of milled rollers e4 and e5 is channeled to accommodate the flat grooved bar E. The tension exerted upon the lace or edging ot by the tensionrollers (t3 and a4 and the milled rollers c e', c2 e3, and e4 and e5 is sufficient to hold the edging a with the required amount of friction down upon the curved guide-fingers b2 and b3 and to maintain the same also in a dat condition. After all the lace or edging has thus been placed upon the grooved bar E the needle is withdrawn from the bar-and the edging removed from the bar, during which manipu-v lation the tape f is properly inserted in the edging in the usual and well-known manner.

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. In a machine for threading tape into lace or edging, a wheel having radial projections, the peripheral face of said projections having a straight portion terminating in a finger, all arranged so that the distance between successive bars of the lace or edging to be fed is less4 than the distance between successive projections on said wheel.

2. In a machine ot the character described, in combination with means for feeding the edging, a star-wheel, the projections of which having a straight face terminating in a finger, said straight face adapted to engage and to permit a movement of alternate bars of said lace or edging and to be rotated by said bars by abutting against said fingers.

3. In a machine of the character described, in combination with means for feeding the edging, a star-wheel having projections and straight faces terminating in a finger, the straight faces of said projections and the intervening spaces between the same adapted to receive and to permit a certain forward movement of the bars of said lace or edging.
