TEXTILE-MACHINE.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application filed November 12, 1914. Serial No. 871,824.

To all whom it may concern:

Be it known that we, EDGAR F. HnTiIAWAr and CHARLES LEA, both citizens of the United States, and residents of Boston, county of Suffolk, Commonwealth of Massachusetts, (whose post-office addresses are 195 Freeport street, Dorchester, lllassachusetts) have invented an Improvement in Textile-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to the manufacture of carpets or rugs of the Axniinster or similar types, and aims to provide a simple and effective mechanism whereby the comb or yarn spacer may be applied automatically to the yarns to maintain the same in their "established pattern arrangement after being wound on the spool iiith'elspooling machine and until they are drawn through the tubes of the tube frame which is ordinarily employed with carpet looms of this class.

The character of the invention may be best understood by reference to the following de scription of an illustrative embodiment thereof shown in the accompanying drawing, wherein:

Figure 1 is a vertical longitudinal section through an illustrative spooling machine shown herein as embodying the invention;

Fig. 2 on an enlarged scale is a view partly in elevation and partly in section of a portion of the comb holder and the lifting mechanism therefor;

Fig. 3 is a plan of the machine shown in Fig. 1; and

Fig. 4 on an enlarged scale is a portion of the comb used in the machine having a clamp applied thereto for holding the yarns therein.

Referring to the drawing, the illustrative machine shown therein as embodying the invention comprises side frame plates 1, 1 on which are mounted standards 3, 3 in which is journaled the shaft of a. spool 5 drivenby a gear 7 fast thereon, said gear in turn being driven by a larger gear 9 journaled in bearings in the side plates .1, 1. Suitable rolls 11, 13 and 15 are provided to contribute to the proper winding of the yarn on the spool 5.

The yarn is led to the wlndlng mechanism described from bobbins (not shown). To

17 mounted on atransverse bar 19 secured to the side plates 1, 1.

To measure the length of yarn wound, upper and lower measuring rolls 2'1 and are provided intermediate the reed 17 and the spool lhe lower roll 23 is mounted on a shaft journaled in bearings in the side plates 1, 1. The upper roll 21 is mounted on a shaft 27 journaled in boxes 29 adapted to slide vertically in guideways 31 in uprights projecting upward from the side plates 1, 1. Thus the upper roll 2-1 may rest on the yarn and give the same sullicient traction on the roll 23 to rotate the latter. To lift the upper roll 21 up away from the yarn the boxes 29 are connected by links 35 with cranks 37 on a shaft 39 journaled in bearings in the uprights 33 referred to.

After the appropriate length of yarn has been wound on the spool a comb 41 is projected upward to present its teeth between the yarns to maintain the same in their proper relation. This comb is mounted in a holder bar 43 adapted to slide vertically along the face of the reed supporting bar 19 referred to. The comb when in the holder fits between two pins 43 adjacent the ends of the holder, thereby locating the comb so that its teeth aline with the pegs of the reed and insure the passing of the teeth of the comb between the yarns when the comb is elevated, as more fully hereinafter described. To guide the holder 43 in its vertical reciprocation it is provided .with studs 45 projecting from said holder into vertical slots 47 in the bar 19.

o elevate the holder cam levers 49 are provided pivoted on pins 51 projecting from the bar 19. The upper ends of these levers are rounded and adapted to engage the under edge of the holder while their lower ends are connected by a link 53 so that said levers may be rocked in unison. 53 is connected by a shipper bar 55 with a handle 57, said ba-r'being adapted to slide through an opening in one of the side plates 1. When the holder is pulled outward it will rock the levers 49 from their full to their dotted line positions shown in Fig. 2, there- 'by elevating the comb and its holder upward to present the teeth of the comb'between the yarns. When the handle is shifted inward it will rock the levers back from their dotted The link to their full line positions, thereby permitting the holder to gravitate downward to its original inactive position.

An important feature of the present invention relates to mechanism for automatically elevating the comb to present its teeth between the-yarns. To accomplish this the shipper lever is provided with a helical sprmg 59 confined between a ring 61 fast thereon and the outer face of one of the side plates 1. This spring tends to shift the shipper bar to the left of Fig. 2 and thereby elevate the comb and holder. To lock the shipper bar against such movement a latch lever 63 is pivoted on a stud 65 projecting inward from one of the side plates 1 and is adapted to engage a spur 67 on the shipper bar. A spring 69 tends to rock the lever and hold the same in locking engagement with the spur 67.

To trip the lever after a predetermined length of yarn has been wound, the shaft of the lower measuring roll 23 has a pinion 71 fast thereon adapted to drive a large gear 7 3 fast on a shaft journaled in the machine frame. Projecting from this gear is a trip pin 75. After the pinion 71 has rotated a sufficient number of turns to imparta complete rotation to the gear 73, the trip pin 75 will engage the tail of the latch lever 63 and rock the same up out of engagement with the spur 67, thereby releasing the previously energized shipper bar 55 to the action of the spring 59 which will shift said bar to the left of Fig. 2 and automatically elevate the holder and comb to present the teeth of the latter between the yarns.

To prevent the yarn from slipping out of the comb a cap piece or retainer 77 is provided adapted to slip over the points of the teeth and be held by a resilient linger 79 secured adjacent each end of the comb.

After the comb is removed from its holder it is attached to the spool by any suitable means to prevent inadvertent displacement thereof in the handling and transferring of the spool from the setting machine to the machine in which it is to be used. Then the handle 57 is pushed inward against the resistance of the spring 59 and automatically locked by the engagement of the latch lever 63 with the spur 67. This inward movement of the handle shifts the shipper bar and rocks the cam levers from their dotted to their full line positions, the empty comb holder following the same under the influence of gravity. The holder is then in position toreceive another comb in readiness automatically to apply the same to another set of yarns in a manner similar to that described.

By this invention the comb is applied automatically to the yarns by a very simple and cheap mechanism which is effective in operation and not likely to get out of order.

Having described one embodiment of the invention without limiting the same thereto, what we claim as new and desire to secure by Letters Patent is:

1. In a yarn setting machine, the combination with spool holding means, of means for turning the spool to wind on the yarn, a. yarn spacer with means for automatically applying the same to the yarn, means normally locking said spacer against its automatic application, a measuring roll engaging the yarn in its passage to the spool and a apted to be turned an amount proportionate to the length of yarn delivered to the spool, and means operated by a predetermined movement of said measuring roll to release said locking means.

2. In a yarn setting machine, the combination with means for holding the spool, of means for turning the same to wind on the yarn, a yarn spacer, means for automatically applying the same to the yarns, a measuring roll adapted to engage the yarn in its passage to the spool and to be turned an amount proportionate to the length of the yarn delivered to the spool, and means actuated by said measuring roll for controllingthe automatic application of the yarnspacer to the yarns.

In testimony whereof, we have signed our names to this specification in the presence of two subscribing witnesses.
