Patented May 27, 1930 UNITED STATES PATENT FFEE EDGAR F. HATHAWAY, OF WELLESLEY, MASSACHUSETTS, ASSIGNOR TO- SHAWMUT ENGINEERING COMPANY, OF DORCHESTEB, IVIASSACHUSETTS, A CORPORATION OF MASSACHUSETTS YARN CARRIER es TUBEFRAME Application filed May 1,

My present invention deals with the handling of sets of threads or yarns, especially tuft yarns for moquett-e or other pilefabric looms such as Axminster carpet looms, and more particularly aims to provide improved means for holding and presenting such threads or yarns in preparation for and during the weaving operation. This application is a division of my co-pending apslication Serial No. 817,728, filed November 7 1928, the latter in turn being a con tinuation in part of my application Serial No. 290,916, filed July 7, 1928.

In the drawings illustrating by way of example one embodiment of my present invention. r

Fig. 1 is a plan of a portion of a tuft-yarn carrier or tube-frame in accordance with the invention v Fig. 2 is a vertical cross-section through the same; and i Fig. 3 is a bottom perspective View of a portion of an attaching strip.

In the illustrative embodiment of the invention, the tuft-yarn carrier or tube-frame comprises a frame or main longitudinal supporting element 1, shown as a tubular metallic member or bar but which may be of other material or otherwise formed, for instance, as a wooden bar. The length of this frame or carrier proper is such that it may support along it one or more tuft-yarn spools of customary length. Each such spool is rotatably supported upon the frame and the latter is adapted for connection with the carrier chain of a loom, in any desired or usual manner, for example, as illustrated and described in 1y applications above mentioned.

The ends of the series of yarns or yarn units depend from the supported spool or spools across one face of the frame 1, that at the left as viewed in Fig. 2. For the purposes of the present application that side or face of the frame across which the yarn ends extend is referred to as the frame front, whilethe face or portion of the frame at an angle thereto and below it is'termed the.-

under portion or bottom of the frame.

Along one face of the frame, the bottom face as herein'illustrated, I provide means 192s. seen No. assess.

for spacing the yarns and for guiding the yarnengaging devices or grippers of the loom. This means as shown comprises a longitudinal series of wall-forming barriers, guide members or guides 9. are preferably metallic strip-like devices or bars distributed along the frame in edgewise relation thereto, each having one end extending outwardly or laterally beyond the bottom face of the frame and at the side across which the yarn ends extend.

The barriers or guides 9 are removably secured in their relation substantially as illustrated as by means of'an'attaching strip 10 having apertures 11, see Fig. 3, at suitable intervals for receiving fastening means such as screws or. bolts 12, Fig. 2, which extend through corresponding openings in the adjacent face,herein the bottom face, of the,

frame 1 and removably engage the opposite frame wall through the medium of lock nuts 18 or the like. The edge of each such opening 11 in the attaching strip preferably is up-set as indicated at 1 1, Fig. 2, to facilitate and insure accurate'positioning of the attaching strip relative to the frame.

The attaching strip 10 as illustrated comprises a flange 15 depending along one side portion of the strip. I This flange, together with the adjoining portion of the strip if desired, is provided with a series of formations such as slots, notches, perforations or the like 16, each adapted to receive the adjacent portion, herein. the inner end portion, of one barrier or guide 9 of the series. The inner end portions of said barriers are adapted to be received in these formations, preferably with a slightly loose fit, each having at their 'exs tremity a tongue 17 for reception in the appropriate formation 16 of the attaching strip.

These guides Additional means for positioning and reand of the carrier bar, and adapted to ha rib 18, in the form illustrated and described,

thus comprises in effect a series of straps or eyes aligned lengthwise of the attaching st'ap passed through and beneath them a lockiin pin or bar 20, the latter passing through locking formation or aperture provided fo the purpose in each of the guides 9. th s. holding or looking the latter removably in assembled position.

The outer or projecting end portions of the several barriers or guides 9 are formed as substantially straight noses S0 of a somewhat reduced vertical dimension as compared with the main portion of each. Cooperating with these portions of the several barriers or guides l have provided means for retaining the respective yarn units in proper spaced relation, one between each two adjacent guides, this means beingconstructed and arranged to permit broadside threading or positioning of the yarns in said relation when desired. This yarn retaining means may be formed as a part of the attaching strip 10 or as a separate longitudinal element or plate 31 posi tioned flatwise against'the adjacent portion, herein the under face, of the frame 1, intermediate the latter and the attaching means 10, being provided with like-spaced apertures as the attaching'strip 10 for the passage of the securing means 12. This plate 31 projects laterally at the front face of the frame and inprorzimity to the projecting portions of the several barriers 9. At its outer or projecting portion it is stamped, sheared or otherwise formed to provide a series of frontentrance passages 32 into which the yarns may be threaded in a broadwiso manner and wherein they will be positively retained by deflected portions, teeth or barbs As clearly seen in Fig. 1, these off-set portions or barbs extend across and completely close in the spaces intermediate the respective guides '9, thus providing substantially continuous walled or inclosed guide passages from which the yarns may not escape in a broadwise manner unless they are intentionally bent or deflected about the respective barbs. They may. however, readily be entered into said guide spaces in a broadwisefashion as previously described. 7

It will be understood that my invention is not limited to the particular illustrative means shown and described, its scope being set forth in the appended claims:

1. In a yarn carrier or tube-frame, in combination with a main frame or carrier bar,

frame, having one side portion overlying the projecting ends of the barriers and formed Wltll' a correspondlng series of broadsidethreadable yarn passages, one between each two adjacent barriers, and with a deflected or barb-like portion for each such passage to prevent reverse escape of the yarns, and attaching means comprisingtwo series of formations along the frame for individually receiving and positioning the respective barriers, the formations of theseries nearer the frame front being of less vertical extent than the barriers.
