'YARN-CARRIER BUPPQBT..

To all whom zt may concern:

Be it known that I, BURT A. PETERSON, a citizen of-the United States, residing at Rockford in the county of Winnebago and State of Illinois, have invented certain new and useful Improvements in Yarn-Carrier Supports, of which the following is a speci- .iicatlon In application Serial No. 781,919, led July 30, 1913, by Howard D. Colman, is shown a warper creel comprisin sections therein termed tridents Eac trident comprises a base to which is fixed three parallel spindles, each spindle being of suiicient length to support four yarn masses termed The tridents are adapted to be used at the spooler or Winder as receptacles or su ports for the yarn masses when remove from the spooler or Winder, and are adapted to be transported to and placed upon the framework of the warper creel.

In order that the cheeses maybe rewound upon the section beam of the warper at high s eed and under low tension, it is necessary tliat the cheeses shall be so sup orted by the tridents as to rotate with the east possible friction. It also is very important that the pivotal supports o'r bearings of the cheeses in the tridents 'shall be of such nature as to require no attention in the way of adjustment or lubrication during relatively ,long periods Aozf' use.

One of the objects of this invention is to improve the trident shown in said application Serial No. 781,919 with a view to reducing friction and minimizing the attention necessary to maintain the pivotal supports of the cheeses in satisfactory working condition. This object has been attained by providing ball bearings for the trident rollers and y providing means for eiliciently lubricating the bearings, the lubricating means being of such character as not to reuire replenishment of oil or other attention uring relatively long periods of use. When the tridents are in use at the Winder or are'being transported from the Winder to the warper creel frame, the Itridents stand u on their bases Withthe spindles in upright position. When "in such pos1t1on the yarn carriers on a given splndle rest upon l one another. When the tridents are in use Bpeoloation of Ilettera Patent.

to move the yarn carriers laterally until each is supported entirely upon its individual roller.

.Another of the objects of the. present inventlon is to provide means whereby the necessity for such manual positionin of the yarn carriers upon the rollers sha be obviated, and whereby, when the section beam to which the cheeses are attached is revolved, the cheese shall move laterally until each is properly located upon its roller.

The lnvention also relates to the other features of improvement hereinafter set forth. In the accompanyin drawings, Figure 1 1s a fragmental view 0% a trident and a part of the means whereby the trident is supported in the warper creel frame, the yarn masses and yarn carriers being shown in longitudinal central section. The yarn carriers are illustrated in the osition'l which they may 'at first occupy in t e creel. Fig. 2 is a view generally similar to Fig. r1, but showing the yarn carriers ashaving been moved laterally into operative position upon their respective rollers. Fig. 3 is a fragmental longitudinal sectional view upon a larger scale. Fig. 4 is a fragmental v1ew` of0ne of the trident rollers showing the position of the oil level when the trident is in use at the Winder or is being transported to the creel. Fig. 5 is a fra mental view illustrating the constructiont at enables the cheeses to cross the spaces between the rollers.

'In the drawings a indicates a cheese consisting of yarn spirally wound upon a tubular core b. In the form of cheese core herein shown, the axial opening of the cheese core is defined by inturned end flanges b. Within the core is a sleeve b that extends from 'one flange b* to the other and surrounds said `flanges.

In the creel the cheeses are rotatably supported upon spindles 1, four cheeses, in the present embodiment, being carried by each s indle. The cheese cores are not mounted directly upon the spindle, but are carried by rollers 2 which are rotatably supported upon the spindle." In the construction herein shown, the roller is formed of sheet metal.

Ball bearings are interposed between the Azo through an opening 9 in the sleeve yhas a generally crowning periphery.

roller and the spindle. While the ball bearings may be of any suitable character, the construction selected for illustration comprises a sleeve 3 which is mounted upon the spindle 1, the ends ofsaid sleeve being expanded to form ball races 4. Each roller 2 comprises' inturned llanges 5 which are bent toV form ball races 6. Between the ball races d and 6 are placednballs 7. lnwardly of the ball races 6, each flange 5 is continued to form an annular lip 8. To lubrcate the ball bearings, a small quantity of oil wis placed in each roller 2 before the roller is placed upon the spindle, the oil being introduced fllen quantity of oil is such that the level of the oil never touches the sleeve 3 Whether the spindle is in horizontal or in vertical position, the level of the oil never reaching the lip As shown in the dra-wings, the rolle; 2 hail@ end portions of the roller are tapered to provide surfaces 10 for supporting the bearning langes'b* of the cheese core. The remainder of the periphery or the roller is cylindrical.. As indicated in Fig. 3, the rollers are relatively close together.

lin the construction herein illustrated, the trident comprises a base 12 which may be ci wood. The spindle 1 is secured to the base 12 by means of an attaching member 13. Upon the outer end of each spindle is a tubular tip or cap 14: which for convenience in manufacture is made rotatable, said tip being mounted upon a sleeve 15 having an out-turned flange upon its inner end. 'The sleeves 3 are spaced away from each other Aand from the attaching member 18 and the tip 14 by means of sleeves 16 having outturned end flanges that abut the flanges of the sleeves 3 and 15. The seriesof sleeves 3, 15 and 16 is clamped against the attaching member 13 by means of a nut 17 screwed upon the outer end of the spindle 1.

A.' spool 18 is rotatably mounted upon each sleeve 16. As shown in F ig. 3, the ends of the rollers 2 are countersunk so as to overhang the spools 18. These spools receive any yarn which may get 'between the rollers 2 or between said rollers and the attaching member 13 and the tip 14. In case some yarn should become wound upon one of the spools 18, the yarn may be readily unwound therefrom by the operative, since the spool will rotate freely as the yarn isvvithdrawn.

As heretofore stated, when the tridents are in use at the Winder or in transit between the Winder and the warper creel, they stand upon their bases 12 with the spindles 1 in upright position. When in such osition the cheese cores on a given spindle rest upon'one another. As positioned in the creel the spindles are horizontal. The threads of the cheeses having been connected to the section beamv of the warper, said beam is rotated to Wind the threads'thereon. Re-

ferring now to the cheese core which is near- Y est vthe, base l2 in Fig. 1: It will be observed" than the other end of the cheese core, and

hence the cheese is caused to cant, as a result oi which the cheese core Amoves sidewise as it revolves until it has reached a central position upon its roller, when both ends the sleeve b5 rests upon the cylindrical por-,

tion of the roller 2 at the time one of the llanges b4 is directly over the space between the rollers, so that itis impossible for the flange b4 to drop low enough to catch on the end of the roller onto which the cheese is icc moving. inasmuch as the contacting porroller and takesthe load od the sleeve b5.

Referring to. the self-oiling feature'. When the cheeses are rotated the oil is spread over the inner periphery of the rollers 2, and when the cheeses are stopped some of the oil creeps over the anges 5 and the lips 8 and thus enters the bearings. The lips 8 increase the distance through which the oil must creep and thereby reduce to the desired extent the amountof oil that reaches the bearings. The amount of oil that reaches the bearings at any given stoppage is so small that the supply contained in the roller lasts :tor a long time.

1t will be seen thateach roller 2, with its sleeve 3 and series of balls. 7, constitutes a self-contained roller unit which `may be readily placed upon or Withdrawn from the spindlel when necessary.
