Specification of Letters Patent.

Patented Sept. 14, 1915.

Continuation in part of application Serial No. 533,408, filed December 16, 1909. This application filed July '18, 1912. Serial No. 710,124.

To all wiz am it may concem Be it known that I, CHARLES LEA,a citizen of the United States, and a resident of Boston, county of Suffolk, State of Massachusetts, (whose post-oilice address is corner of Freeport and Beach streets, Dorchester, Massachusetts) have invented an Improvement in Yarn-Holders, of which the following description, inconnection with the ac oompanying drawings, is a specification, like characters on the drawings representing like arts. p This invention relates to yarn holding devices employed in connection with the manufacture of carpets or rugs of the Axminster or similar types, being more particularly concerned with the provision of improved means for maintaining the tuft yarns in.

their established-pattern arrangement after being wound on the spool in the spooling machine and until they are drawn through the tubes of the tube frame Whichisordinarily employedwith carpet looms of this class.

The invention will be best understood by reference to the following description when taken in connection with the accompanying illustration of one specific embodiment thereof, while its scope will be more particularly pointed out in the appended claims.

the drawings: Figure 1 shows in perspective, partly broken away, a yarn holder embodying one form of my igvention; Fig. 2 shows the same yarn holder applied to a spool; Fig. 3 shows on a larger scale in plan the construction of one end of the holder;

and Fig. 4 shows the same end in side elevation.

In the preparation of the tuft yarns for the tubing operation the yarns are Wound upon the spool of the spooling machine while held separated by the usual reed or separator and in a prearranged pattern. At such time it is customary to apply to the yarns a toothed comb or holder whereby in yarns to the tubing machine, they may be maintained in the same separated condition and drawn accurately through the tubes of the tube frame.

In actual manufacture, considerable time usually elapses between the spooling operation and the tubing operation. It is customary to wind on a large supply of spools in advance of actual requirements and these to the spacing of the 7 ing machineand the spools are then stored away and may be kept for long periods of time before they are placed in the tubing machine. It is,.however, requisite that in whatever condition the spools are kept or however long they are kept the yarns be maintained separated in the same fashion as they originally came from the spooling machine. It is also requisite that they be so constructed that when applied to the spool and the latter is stored With other spools, or transferred from one place to another, they have no tendency to catch upon or otherwise disarrange the yarns upon their own or adjacent spools with which they may come in contact.

Referring to Fig. 1, I have there shown a transfer comb or holder 1, preferably formed of sheet metal. and presenting a series of projecting teeth 2, the latter being predeterminately spaced according to the spacing of the tuft yarns with which the comb is to be employed, which spacing will correspond reed teeth in the spoo1- tubes in the tube frame. applied in any suitable yarns in the spooling yarn will enter between This comb may be manner to the tuft machine, so that the theteeth 2. The lower ,edge 3 of the comb,

may be curled over as shown, which causes the comb to present a smooth lower edge and also serves to give stiffness to the comb, and permit its ready application to a suitable holder in the spooling machine.

WVith the yarns entered between the teeth of the holder, they are then prevented from slipping out of the comb by the application thereto of a cap-piece or retainer 4, the lat ter consisting preferably of a sheet metal strip bent into a U-shaped cross section and adapted to slip over the points of the teeth and close the mouths of the slits against the exit of the yarn strands. The cap may be so proportioned with reference to the depth of the slits as to clamp the yarns therein, but

preferably the slits are deeper than the sides of the cap so that the free, longitudinal .draft of the threads between'the teeth is not be employed for securing the resilient finployed bottom' of the groove,

ready application of the cap to gers in position, but herein each finger is shown as provided with a bottom projection or tang 6. The finger being seated upon the the tang projects 7 in the bent-over edge 3 throu h an opening g rovided to hold the and a single rivet 8 is finger firmly in place, t e its displacement. The end of the finger is bent'at Q and prolonged to overlie the end of the cap-piece. To provide a secure fastening for the cap-piece the end of the bend in the finger is curved so as to lie transversely over the cap-piece at 10, and the end of the cap-piece is formed with a shouldered or flattened portion 11 to form a seat for the bent retaining end, of the resilient finger. The described construction permits the the comb, the fingers easily snapping into flposition upon the seat on the cap, serving e ectively to retain the cap under the severest conditions of usage. The locking finger, however, is sufiiciently resilient to permit its projecting portion to be pressed back for the release of the cap and the withdrawal of the latter from the comb or work. With the retaining cap in position the holder may be then attached to the spool by suitable means, so that no matter how much the spool may be handled in transference or how long afterward the tubing operation may be comb cannot he accidentally displaced.

Inthe described embodiment of the invention the comb is shown provided at each end with an attachment member, hereinin the form of a spring 12. The latter hasan eye 13, which may be slipped over the small pintle at the end of the spool 14 and emto attach the comb to the spool, the former having first been laid fiatwise against the wound-on yarn. The comb being drawn fiatwise against the wound-on yarn acts as a or covered. T

clamp preventing the unwinding of the yarn from the spool.

In order to prevent the entanglement of portions of the comb with the yarn strands, all projecting arts are carefully protected lie bent over edge 3 and the U-shaped cap provide smooth edges for'the comb. At the ends the projecting corners are rounded at 15 and 16, as is also the corner 17 of the resilient finger, 18 of the cap. The retaining member 10 of the finger is also rounded, as is the shouldered ortion of *he ca seat, so that there are le t no pointed pro ections apt to catch in the yarn. This provides which may be used in connection with the spools with entire safety and security.

A I While I have herein shown and. described one specific embodiment of my invention for illustrative purposes, it is to he understood that the invention is not limited to'the construct onal details herein shown, but that extensive deviations may be made from the tang 6 preventing.

performed, the

. ranged pattern to and the corner a yarn holder form herein shown without departing from the spirit of the invention.
