i provide an improved and simplified means for supporting and presenting spooled tuft yarns in the course of Weaving. As to all common subject matter this application is a continuation in part of my copending application Serial No. 290,916, filed July 7, 1928.

In the drawings illustrating certain embod- Vents of the invention Fig. l is a front elevation of one end of a yarn Carrier or tube frame With supported yarn spool;

Fig. 2 is a. vertical section transversely through the carrier and spool of Fig. l, showing also a port-ion of a yarn engaging instrumentality of the loom in position about to Fig. 3 is a bottom plan of the carrier as in Fig. l;

Figs. et and 5 are respectively perspectives of a single yarn-spacing and gripper-guiding member such as 'llustrated in Figs. 1 to 3, and

a section of an attaching` element or strip therefor; and

Figs. 6 and 7 are respectively a vertical cross-section through a modified form of cariier, and a. plan of a portion thereof.

Referring more particularly to the drawings and first to Figs. l to 5, the tuft yarn carrier or tube frame as illustrated` comprises a frame l or main longitudinal sup- 5 porting element, shown as a tubular metallic member but which may be of other material or otherwise formed, for instance, as a Wooden bar. Said frame or carrier proper is of a length to support along it one or more tuft yarn spools, as required, a portion of one spool being shown at 2. The spool is rotatably supported upon the frame as by means of the bearing member 3 receiving the spool pintle e, similar means being provided at the opposite end of the frame, and at an intermediate point or points Where a plurality of spools are to be supported. The frame is adapted for connection with the carrier chain o the loom in any desired or usual manner as i by means of the chain engaging member 5 and the hook-latch G provided at each end of the carrier frame.

The series of yarns or yarn units 7 extend from the spool 2 upon which they are Wound across one face of the frame l, that at the left as viewed in Fig. 2. For convenience in description this side or face of the frame, across which the yarn ends extend, Will be referred to as the frame front, While the face or portion of the frame at an angle thereto and below it Will be referred to as the under portion or bottoni of the frame.

Along one face of the frame, the bottom face as herein illustrated, is provided yarn spacing and gripper guiding means herein comprising a longitudinal series of guide members, guides or barriers 9 illustrated as metallic strip-like devices or bars distributed along the frame in edgewise relation to it and each with one end extending outwardly beyond the bottom face of the frame, at the side across which the yarns 7 extend.

Suitable means is provided for attaching said yarn-s acing and gripper-guiding means to the frame l. Herein for the purpose there is illustrated a longitudinal element or attaehing strip l0t best seen in Fig'. 5, having at suitable intervals apertures ll for receiving a Afastener such as the screw or bolt l2, Fig. 2, extending through corresponding openings in the adjacent face, herein the bottom face, of the frame 1 and removably engaging the opposite frame Wall as by means of the locknnt 13. rllhe edge of the fastener-receiving apertures ll of the attaching strip may be 11p-set as indicated at le, Figs. 2 and 5 to insure accurate positioning` of the attaching strip upon the frame.

Said attaching strip as illustrated is formed with a depending flange 15 which, together with. the adjacent. portion of the strip, if desired, has a series of formations such as slots, notches, perforations or the like 16. each adapted to receive one end, herein the inner end, of one element or member 9 of the spacing and guiding means. The inner ends of said members or guides 9 are. adapted to be received in said formations 1G, pref-erably with a slightly loose lit, and as shown are formed each with a tongue l? for reception in llt) the corresponding formation 16 of the attaching strip 10.

Along a portion of the attaching strip spaced from the flange 15 additional means for positioning and holding the yarn-spacing and gripper-guiding members or guides preferably is provided. Said means as herein illustrated is of relatively small height as compared with the flange 15, being in the form of a hollow or approximately U-shaped rib 18 bent or struck up from the body of the strip lO and preferably rounded substantially as illustrated. Said rib 18 is formed with a series of slots, notches or the like 19 registering with the formations 16 of the strip flange and of a width to receive each a guide 9, also ireferably with a slightly loose lit, said rib thus comprising in effect a series of spaced straps or eyes aligned lengthwise of the strip.

The guides 9 are assembled with the attaching strip 10 so that an intermediate portion of each guide lies in a slot or recess 19 of the rib 18 and an end portion, herein the inner one, is received in the corresponding slot,

' notch or other formation 16 of the flange 15.

To hold or lock said guides in assembled position suitable means is provided, such as the locking pin or bar 20 adapted to be passed through and beneath the rib 18 and through a locking formation or aperture 21 provided for the purpose in each guide.

At the outwardly extending ends of the guides 9 means is provided whereby the respective yarn units will be retained in properly spaced feeding position, one between each two adjacent guides, said means being arranged to permit broadside threading or positioning of the yarns in said relation, when desired. In the present embodiment of the invention each guide 9, as best seen in Figs. 1, 3 and 1, accordingly has formed at or near its outer end portion a locking device or laterally deflected barb-like nib 22 having an inwardly inclined forward or outer edge, as indicated at 23. The nib 22 of each guide 9 projects above and to or across that of the next adjacent guide, but spaced suiiiciently from it to permit a yarn unit to be entered past the nib in a broadwise manner, being guided into position by the nib and the adj acent guides. After being entered beyond the nib, a yarn unit is located and retained positively against reverse escape in the yarn passage 2-l, see particularly Figs. 3 and f1, between the inner edge of the nib and the carrier frame.

Said passages 24, as herein illustrated, are further defined by means of additional offsets or shoulders 25 formed on the guides 9 and cooperating with the nibs 22 and with the adjacent portions of the guides 9 to provide a substantially completely surrounding wall for each yarn passage 24, see particularly Fig. 3, in which its yarn unit will be positively retained yet into which the yarn may be entered in a broadside fashion. Accidental lengthwise withdrawal or slipping back of the yarn may be retarded or prevented by forming either the nibs 22 or shoulders 25 or both, as shown, at their opposite under edges with depending and slightly converging burrs, lips or the lilre as indicated at 26 upon the nibs and at 27 upon the shoulders. While the yarns may feed freely downward between said formations 26 and 27, the latter will engage thc yarn libres and prevent upward retraction of the yarns.

lt will be understood that in the weaving operation an instrumentality of the loom, such as the nipper or grippers G shown in part in Fig. 2, is entered into and guided in each inter-guide space to engage or .grasp the yarn therein, to draw it into the warp. By giving the guides 9 a somewhat loose lit in their' supporting means, herein the strip l() as previously described, the resulting slight play affords a certain flexibility in the cooperation of the grippers with the guides, allowing the latter to adjust themselves to the noses of the grippers in case any of thc latter should tend to catch or bind while being inserted or withdrawn. The .shoulders 25 on the guides are also useful in this connection, acting as stops or guides for the inner ends of the grippers and further insuring their proper engagement with the adjacent yarns, as does also the adjacent rounded portion of the rib 18 of the attaching strip.

It will be further noted that the yarns may feed freely down through and between the several guides 9, the space between the latter being entirely free and unobstructed by the attaching strip or otherwise substantially from the outer ends of the guides to their opposite ends, and below the yarn retaining nibs 22 and shoulders of the guides 25 and the shallow rib 18 of the attaching strip 10. Also the guides 9 preferably are markedly recessed or cut away at one or both long edges, as illustrated at 28 in Figs. 2 and 4.

In Figs. 6 and 7, in which parts not otherwise mentioned may be similar as in precec ing figures, the vertical yarn passages and the means for retaining the yarns therein while permitting their broadsidc reception are formed integrally with the barriers or guides 9 as in the form of Figs. l to 5. In this inst-ance the upper forward portion of each of said guides 9 is recessed or stamped out, substantially as illustrated, to form a reversely extending finger or nib which is also laterally deflected, in a sinuous manner, as clearly seen in Fig. 7. The inner end of each of the lingers 35 extends across to and above the recess in the adjacent guide 9 thus barring a yarn positioned in the passage 36 against escape outwardly unless intentionally bent out around the inner end of the finger.' ln the opposite or threading direction, however, the yarns may readily be entered into the respective passages 36 broadwise.
