LOOM FOR WEAVING TUFTED FABRICS.

SPECIFICATION forming part of Letters Patent No. 609,638, dated August 23, 1898.

Application filed May 24, 1897. Serial No. 637,819. (No model.)

To all whom it may concern.-

Be it known that I, EUGENE TYMESON, a citizen of the United States, residing at Yonkers, county of Westchester, and State of New York, have invented certain new and useful Improvements in Looms for Weaving Tufted Fabrics, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

Much difficulty has heretofore been experienced in the weaving by power-looms of tufted fabrics of considerable width, as in weaving tufted carpets of a Width much greater than that of a breadth of such carpet as now usually Woven, on account of the bending of the tuft-yarn spools and spoolframes when the ends of yarn for forming the tufts are beinginserted in the body of the fabric. The object of this invention is to overcome this difficulty and to provide for the weaving of tufted fabrics, and especially tufted carpets, of a greater width than such fabrics are now usually woven; and the invention consists in the features of construction and the arrangements and combinations of parts hereinafter pointed out in the claims.

\Vhile the invention, broadly considered, is applicable generally in looms employing tuft-yarn spools, Whether the spools be removed from the carrying-chains or other spool-carrying devices in inserting the tufts or the yarn drawn off the spools without thus removing them, the invention has been designed in connection with a loom employing transferring-arms by which the spools are carried to and returned from the fabric in inserting the tufts, as shown, for instance, in my prior Patents Nos. 529,636 and 571,418, and the invention includes certain combinations, including transferring-arms, for this purpose.

In the accompanying drawings, illustrating the preferred construction embodying the invention as applied in connection with such transferring-arms, Figure l is a view in elevation of a spool-frame and spool and so much of the transferring-arms of a loom for weaving tufted fabric as isnecessary to show the invention. Fig. 2 is a section of the spool and spool-frame on line 2 of Fig. 1. Fig. 3 is a section of the spool and spool-frame, taken a central longitudinal section through the meeting ends of two of the spools, showing a modification in the arrangement of the bearing-pin for convenience in placing the spools in the frames.

Referring to the drawings, and first to Figs.

1 to 3, the spool-frame is formed of a bar 10, which carries the usual tins 11 and is provided at each end with supports or bearings .12 for the tuft-yarn spool A and the usual catch spring 13 and arm 14 for securing the frame to the carrier-chains, as shown in my patent No. 529,636. The yarn-spool A is formed of two sections a a, having their outer ends formed in the usual manner with a flange and pin and journaled in the supports 12 and having their inner ends formed and supported as follows: Each of said ends is provided with a flange 2, and from the flange on one of the sections a extends a central bearing-pin 3, which enters a socket A in the end of the other section. Around the socket 4 is a collar 5, which enters an opening 6 in a support 15, which extends from the bar 10 between the flanges 2. The end of one of the sections a thus has its bearing in the support 15 and theend of the other section a has its bearing in the first section. A secure bearing may thus be provided with the use of a support 15, formed of a comparatively thin sheet, and this is of great importance, since it is desirable that the end zones of yarn in the two sections of the spool be as close together as possible.

The pin 3, socket 4E, and collar 5 are so proportioned as not to hinder the flanges 2 being pressed against the two faces of the support 15, so that if pressure be applied to the outer ends of the two sections of the spool, so as to hold the ends from moving apart, the end flanges2 will be held pressed against the supporting-plate 15 and it will be impossible for the spool to bendwhere the two sections join, except under a tension great enough to overcome the pressure on the outer ends of the sections, since there can be no bending at this point unless either the flanges move to-' gether on one side, which they are prevented from doing by the support, or the two sections move bodily from each other, which they are prevented from doing by the pressure on the outer ends of the sections.

/ the spool be bent slightly at this joining point arms 22.

of its sections the applicationof pressure to its outer ends will cause the spool to straighten. When the sections a are pressed together also, the support 15 will be gripped between the end flanges 2, thus securing a rigid connection between the spool and the bar 10 at this point.

The transferring-arms 20, only partially shown, by which the spools and spool-frames are carried between the carrying-chains and the point where the ends of yarn are inserted in the fabric to form the tufts, maybe of any suitable construction-as, for example, that shown in the patent above referred toand carry the usual clutches 21, having gripping The clutches 21 are also provided with members under spring-tension, preferably spring-pressed forked arms 23, similar to the spring-pressed arms shown in said patent, which when the transferring-arms are moved toward each other to grip the spoolframe bear on the ends of the spool, so that the sections of the spool will be pressed toward each other longitudinally of the frame, so as to press the flanges 2 against the supporting-plate 15, whereby the spool will be straightened or held from bending and the support 15 gripped between the flanges.

When the spool-frame is carried by the transferring-arms, therefore, the sections of the spool form, in effect, a single spool connected at its ends to the bar 10 and having at an intermediate point by the supportingplate 15 a connection to the bar 10, which is rigid as against any strain less than a strain strong enough to overcome the pressure on the ends of the spool. By making the pressure of the arms 22 sufficient I thus provide, in effect, a frame having two longitudinal bars having a rigid connection at a point intermediate their ends. I thus secure by my invention a construction by which the tuftyarn spool and spool-frame will Withstand the bending strains to which they are subjected and remain practically straight at the time when it is necessary that they should remain so, and this without any objectionable increase in the size or weight or change of the form of the parts. The same result is secured by pressure upon the ends of the spool in the supports in those looms in which the spools are not removed from the chains in inserting the tufts.

The flanges 2 are preferably, for the purpose of securing greater rigidity, of metal and are preferably formed and secured to the ends of the spools as shown.

Fig. 4 shows a spool formed of three sections and a frame therefor constructed according to the invention as above described,

So, also, if

the construction and connection of the spool being the same as in,Figs. 1 to 3, except that one end of the middle section is preferably provided, as shown in Fig. 5, with a springpressed bearing-pin 3 for convenience in placing the section in the spool and similar ,to the spring-pressed pins commonly employed in tuft-yarn spools for this purpose.

It will be understood that the invention as claimed is not limited to the exact construction shown, but includes modifications thereof Within the claims which will secure the results described.

While I prefer to provide the meeting ends of the sections of the spools with bearingfianges, as shown, and while such flanges will generally be found necessary to secure satisfactory results, yet when the spool is of large diameter it may be found sufficient to depend merely on a bearing-face formed by or of the size of the end of the spool. While I prefer to form the flanges 2 as continuous circular flanges and the support 15 of a corresponding form, it will be understood that the flanges may be only partial or broken-flanges, or the support may be of other form than the preferred circular form shown.

What I claim is- 1. The combination of a tuft-yarn-spool frame having end spool-supports and one'or more intermediate spool-supports mounted in the frame on one side of the spool and unsupported on the opposite side of the spool, and a spool formed in sections journaled in said supports and having at their meeting ends opposed bearing-faces to bear against and grip the intermediate supports to prevent bending at the points of juncture of the spool-sections, substantially as described.

2. The combination of a tuft-yarn-spool frame formed of a single bar having end spool-supports and one or more intermediate spool-supports projecting from the bar and unsupported on the opposite side of the spool from the bar, and a spool formed in sections journaled in said supports and having at their meeting ends opposed bearing-faces to bear against and grip the intermediate supports to prevent the spool bending at the points of juncture of the sections, substantially as described.

3. The combination of a tuft-yarn-spool frame having end spool-supports and one or more intermediate spool-supports, and a spool formed in sections j ournaled in said supports and havingtheir meeting ends formed to bear against opposite sides of the intermediate supports and each pair of meeting ends being provided, one with a central socket and a collar around said socket forming a bearing for the spool-section in the support, and the other with a pin entering said socket, substantially as described.

4:. The combination of the bar 10 having end supports 12 and one or more intermediate supports 15, and the spool A formed in sections at journaled in said supports and hav- IIO ing flanges 2 bearing against the intermediate and with a socket 4 and collar 5, respectively, 10 supports 15, substantially as described. substantially as described.
