invented a new and useful Take-Upfor Narrow-WareLooms, of which the followingis a specification.

My invention relates to take-up devices fornarrow-ware loomsloms forweaving ribbon, tape," and similarnarrow fabrics.

Thepurpose of my inventionis to provide means whereby during the weaving'and in conjunction therewith tape, ribbon, and similar narrow fabrics shall be wound, preferably in helicalcoils, to form a self-sustaining package of greaterlength than the width of the fabric, thereby overcoming the entan l'ement and, loss of-time which occurs wheret 'etape iswound in unstable flat; coil's.

For convenience I shall in the following specification and claims refer to narrow'fabric ofwhatever description as tape.

1 The essence ofmy invention is the winding of? tape on a loom in conjunction with the weaving coils, preferably helical. coils, to form self su'staning ackages. of greater axial ofthe tape. This-may be" accomplished by various devices, the folstructure and certain modifications thereof.

helical coils that cross and recross each other,

forming a substantial self-sustaining package of greater aXial'length than the width of the tape, the uniform rate of delivery of the tape causing the spools to rotate with graduallyretarded'speed because of the gradually-increasing diameter of the packages wound upon them.

It is obvious that in order to adapt my invention to various types and structures of looms modifications must be made in the character and relation of the parts constituting my invention. It is also obvious that my invention may be embodied in various forms of structure, and some of these different embodiments and modifications are herewith illustrated and described.

The guides instead of being formed in one long rod, as shown in Fig. 1, may be short individual rods 7", one for each package, and

each mounted in its own individual arm t, as shown in Fig. 3-. The lower-end of the arm t is forked, and between itsbranches is located the collar '8, whereby the arm is restrained from longitudinal movement on its red n.

i The guides may be reciprocated independently of each other, as shown in Fig. 7, by providing for each'guide a cam 4, to which is fitted a sleeve 5, adapted to slide thereon and supporting the guide-arm 20. The cam 4 has formed inits periphery a continuous heliitself centrally thereon.

cal groove 8, extending the length of the cam in one revolution and back again, crossing The sleeve 5 carries a stud or 'pin 6, extending into the groove or track of the cam, forming a journal or bearing for the roll 7. (More plainly shown in Figs. 9 and 10.) When the cam is rotated within the sleeve 5, the latter being held from rotation by the guide 1" on the arm 20 bearing on the package is caused to reciprocate by the roll 7, following the track or groove 8. To prevent the roll from being diverted from its proper course at the crossing 9 of the groove,

a switch '10 is provided. The switch is in the form of a wedge pivoted intermediate its extion indicated by the'arrow, Fig. 10.

'tremities, the latter comprising a tongue 11 and head 12. The cam 4 rotates in the direc- The pressure on the roll is from 'that side of the groove to which the tongue of the switch is swung, as shown by full lines in Fig. 9 and the roll is guided by said tongue at the crossing-point 9 of the groove. As here shown, the spreading-head of the switch extends across the portion of the groove with which the roll is engaged, and after passing the crossing-point the roll makes contact with said head and swings the switch on its pivot into the position indicated by the dotted lines. After the roll has accomplished the full extent of its traverse in one direction it returns in the opposite direction, is guided through the crossing-point of the groove by the tongue of the switch, and again engages the head of the latter to set the switch in the position indicated by the full lines. The shaft 13, on which the cams 4 are mounted, is rotated from the shaft 0 through suitable gear connections, the direction of rotation being toward the latter and tending to maintain the guides against the packages. Again, both guide and package may be reciprocated in conjunction, as illustrated in Fig. 5, in which the spools or holders are shown mounted on a sleeve 14, keyed to the winding-shaft 0, but free to slide thereon. The lower shaft 71. is reciprocated from the cam h, as previously described, and carries the arms 0, supporting the guiding-rod p. Fastened to the opposite end of the loom-frame from that adj acent the cam h is a bracket 15,in which is fulcrumed a lever 16. At either end of the lever 16 are fastened the pins 17, adapted to engage grooves in the collars 18, secured on the shaft n and the sleeve 14. By this means the motion of the shaft 17. is transmitted to the sleeve 14, so that both the guide and the spool are reciprocated. Their movement is 1 in opposite directions, and hence the length of traverse of the tape is equal to the traverse of the guide plus that of the spool. It is therefore only necessary to employ a cam with half the length of throw that is employed when either the spool or the guide is reciprocated singly to secure a package of the same length.

Different provisions must be made for conducting the tape to the winding, depending on the structure of the loom and the relation of the parts. Figs. 8 and 4 show the tape conducted down from the sand-roll and under a guide 1), over a second guide g, which is more clearly illustrated in Fig. 8, and thence under the main guide 1" to the package. In this instance the pressure of the tape on the guide g maintains the guide 1" against the package. As shown in Fig. 7, the spool or holder 9 rotates in the opposite direction from that shown in Fig. 4 and the tape is passed directly from the guide 1) over the guide 1", dispensing with the guide g.

In order that the winding-shaft may be readily disconnected to remove the spools or holders 9, the brackets 19 are formed with one side of the bearings open, the shaft being retained therein by pins or other suitable devices. In the form of device illustrated in v means for depositing -invention Fig. 5 after the shaft has been disconnected it is necessary to remove the collar 18 on the sleeve 14 to free the spools or holders from the latter. Without limiting myself to the precise character, arrangement, or relation of the parts hereinbefore described, I claim as my 1. In a loom for weaving narrow-ware fabrics, the combination with thewinding-shaft,
