SPECIFICATION forming part of Letters Patent N o.h 701,934, dated June 10, 1902.

Application led March 11, 1901. Serial No. 50,539. (Nomodel.)

To LZZ whom iv' may concern:

Be it known thatl I, J oHnF. RIDDELL, a subject of the Kingof England, residing at Clinton, in the county of Worcester andv State of Massachusetts, have 'invented a new and useful Tuft-Yarn Spoolyfor Use in Looms for Weaving Tufted Fabrics, of which thev following is a specification. f; Y

This invention relates'pto an improved construction for `supplying 'differentcolored yarns to a loom for weaving tufted fabrics; and the especial object of this invention is to decrease'the amount of labor and'lessen the expense required in winding different-colored yarns upon the spools employed in these looms. l p ,y

To these ends this invention consists ofthe construction for supplying different-colored yarns to a loom and the combinations of parts` therein, as hereinafter described, and more particularly pointed out in the claims at the end of this specication.

In the accompanying drawings, Figure 1 is a side view of a ruft-yarn spool constructed according to this invention for use in looms for weaving tufted fabrics, the sections of differently-colored yarns being indicated thereon upon an exaggeratedfscale. Fig. 2isa plan view illustratinga portion of a design' for a fabric, that pick or portion of the fabric corresponding with the spool illustrated in Fig. 1 being shown upon an exaggerated scale. Fig. 3 is a side vie'w,"partially broken away, of one of the spool-sections, illustrating the manner in which the removable heads may be secured thereto while said spool-section is being wound `or supplied with differently-colored yarns. Fig. 4 is a perspective view of the parts which may be employed in a complete spool constructed according to this invention, and Fig; 5is an enlarged perspective View of one of the split spring-rings which may be employed for removably securing the spool-heads and vthe connecting-,dowel to the spool-sections.

In that class of looms which are employed for weaving Axminstercarpets or similar tufted fabrics the tuft-yarns are supplied by spools which are mounted in spool-frames normally connected to and carried by endless chains or carriers, which endless chains or carriers are moved or advanced intermittently to present paratively high-priced labor has beenrequired to selecty the properly-colored yarns according to the designers chart or pattern of the fabric to be woven, the successive yarn endsbeing attached to the' core of the spool and the spool then being turned to wind the required,lengthsI ofyarn thereon. In thus loading orwi'nding'the spools for use in looms for weaving tufted fabrics it has heretofore been' requisite to exercise an individual se# lection or picking out of the proper colors of yarns across the entire width of the fabric-to be woven.

The especial object of my present invention is to decrease the labor required in loading or'winding the spools for certain classes of fabric designs, and I accomplish this result by reason ofthe fact that in a Very large percentage ofdesigns the, ligures or colors are repeated "at different `points across vthe width of the fabric, requiring they Lsa'mesequence of colors in the tuft-yarns for weaving the same. For example, in nearly all stair-carpet designs the fabric is symmetrical with respect to its central line`,"and whenv such a fabric is to be woven I proposeito take *l advantage of this fact by dispensing with the necessity of requiring a selection of properlycolored yarns for the entire width'of thevfabric, and insteadV of requiring such selections of yarns I propose to employ. forweaving each line oftufts of a fabric of `this classtwo independent spool-sections having yarns in the same sequence of colors wound thereon, the spool-sections being journaled end to end, but inverted with respect to each other, so that the sequence of colors on the spool-sections will be symmetrical with respect to the adjacent ends of the spool-sections and the spool-sections will be turned in opposite directions when a supply of yarn is being drawn therefrom. The application of my invention is not limited, however, to designs which are symmetrical with respect to their center line,` but is equally applicable to all designs in which there is a repetition of the gures across the width thereof requiring either the same sequences of colors or inverted sequences of colors.

In practicing my invention I propose to employ spool-sections having sockets at their ends for receiving detachable heads or for detachably receiving a connecting-dowel for holding two adjacent spool-sections together while permitting them to rotate independently. The detachable heads and the connecting-dowel are preferably held in place by means of split spring wire rings inserted into sockets in the spool-sections, although it is to be understood that the mechanical details of the construction which lI have herein illustrated for the purpose of practicing my invention are in no way essential to its successful application, and that I do not desire, therefore, to be limited to the particular features of such devices which I have herein illustrated.

Referring to the accompanying drawings and in detail, the spool illustrated in Fig. l comprises two spool-sections A and B. The spool-sections A and B are provided with recesses l0 near their ends for receiving split spring-rings 1l, and the ends of the spool-sections A and B are bored out or provided with sockets for receiving either the connectingdowel 12 (illustrated in Fig. 4) or a shank let of one of the detachable heads 13.

Referring now to the design illustrated in Fig. 2 for an understanding of the application of my invention, it will be seen that this design is symmetrical wit-h respect to its center line, as is also the case with a great majority of staircarpet designs and certain other fabrics, designs of this class being especially common for rugs.

To load or wind a spool according to my invention for such a design, each of the spoolsections A and B iirst have detachable heads secured thereto, as illustrated in Fig. 3, and then have the same sequence of colored yarns wound thereon.` The spool-sectionAis then inverted with respect to the spool-section B. The inner removable heads are taken off, and the two spool-sections are connected by a connecting-dowel 12. This will bring the sequence of colors on the two sections A and B in inverted order with respect to each other. For example, the colors a, b, c, and d appearing on the spool-section B also appear on the spool-section Ain the reverse order in the same manner that the colors of the tufts a, b, c, and CZ (illustrated on an exaggerated scale at one side of Fig. 2) appear in the reverse order at the opposite side of the design. Vhen two spool-sections are thus loaded or wound and associated together to form a line of tufts for a symmetrical design, one spoolsection A will be turned or rotated in one direction when the yarn is being drawn therefrom, and the other spool-section B will be rotated or turned in the opposite direction when the yarn is being drawn therefrom, and it is on this account that it is desirable to provide a connection between the two spool-sections which will permit them to revolve independently of each other. l

From this explanation of the application of my invention to produce a design symmetrical with respect to its center line it is believed that the use of my invention for all designs in which a repetition of color-sequences occur will be obvious to those skilled in the art. For example, where the pattern is repeated at two or more places across the breadth of a fabric being woven two or more similar spool-sections would be associated together; but in such cases the spool-sections would turn in the same direction when yarn is drawn therefrom instead of turning in opposite directions, as when weavinga symmetrical design.

I am aware that numerous changes may be made in practicing my invention by those who are skilled in the art, and in many cases it is not essential that the spool-sections should be of the saine length, and for many uses spool-sections of different lengths may be employed for different portions of a design across the breadth of the fabric. I do not wish, therefore, to be limitedtto the construction I haveherein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, is-

l. In a construction for supplying differently-colored yarns to a loom for weaving tufted fabrics, the combination ofspool-sections having yarns supplied from the saine yarn ends wound upon each of said spool-sections, so that said sections will have the same sequence of colors thereon, said sections being connected together so as to be independently rotatable.

2. In a construction for supplying differently-colored yarns to a loom for weaving tufted fabrics, the combination of two independently-rotatable spool-sections having yarns of the same sequence of colors wound thereon, said spool-sections being journaled in line with each other, so that the color sequences on said spool-sections will be symmetrical with respect to the adjacent ends of the spoolsections, and said spool-sections being arranged to turn in opposite directions when supplying yarn for a design symmetrical with respect to its centerline,substantially as described.

3. In a construction for supplying differently-colored yarns to a loom for weaving tufted fabrics, the combination of spool-sections, a dowel-for connecting said spool-sections so that they may rotate or turn independently of each other, and spool-heads adapted to be detachably connected to the ends of the spoolsections, substantially as described.
