Specification of Letters Patent.

Patented Aug. 6, 1918.

Application filed November 28, 1816. Serial No. 133,982.

To all whom it may concern:

be it known that I, Howann D. COLMAN a citizen of the United States, residing at Rockford, in the county of Winnebago and State of Illinois. have invented certain new and useful In'iprovements in Yarn-Carrier Supports, of which the :tollmving is a specitieation.

Spools, cheeses or other yarn masses, when taken from the spooler or winder on which they were produced, have heretofore been deposited in suitable receptacles for transportation to the warpcr creel. where the yarn masses were placed in position in the creel, oneby one. When the spools or cheese cores were empty, they were removed, one by one, "from the creel, and placed at points adjacent to the spooler or winder. These operations necessitated much rehandling oi the yarn masses and empty spools or cheese cores. One of the objects of this invention is to reduce the amount ot handling ot the yarn masses andcontainers, and avoid the possibility of injury to the yarn which is incident to the previous methods of handling and transporting yarn masses. This object is attained by constructing the warper creel with removable sections adapted to be used at the spooler 0r winder as a receptacle or support for the yarn masses when removed from the spooler or winder. and adapted. to be transported to and placed in the creel.

Another object of the invention is to provide a yz'trn-earrier support which shall permit rotation of the yarn carrier with a minimum amount of friction.

The invention also relates to the further improvements hereinafter described.

In the accompanying drawings Figure 1 is a fragmental. vertical sectional view of a creel embodying the features of my invention, showing a trident in place in the supporting :l"rame. Fig. 2 is a vertical sectional view taken approximately in the plane of dotted line 2 of Fig. 1. Fig. 3 is a fragmental longitudinal central scctional View of a spindle and rollers comprised in the trident. Fig. lis a sectional view of the trident.

While the invention may be used in connection with various forms of yarn masses, it is herein illustrated as embodied in apparatus for supporting yarn masses in the form of cylindrical chooses a. Each cheese consists of yarn cross-wound upon a tubular core Z). In the illustrative :lorm herein shown. the axial opening of the cheese core is defined by inturned flanges Z).

In the creel the cheeses are rotatably supported upon spindles 1. four cheeses. in the present embodiment, being carried by each spindle. The cheese cores are not mounted directly upon the spindle. but are carried by rollers 2 which are rotatably supported upon the spindle. Tn the construction herein shown, each roller is formed of sheet metal. It" desired. ball bearings may be interposed between the roller and the spindle. In the construction selected for illustration. a sleeve 3 is mounted upon the spindle 1, the ends of said sleeve being" expanded to form ball races 4. Each roller 2 comprises inturned end flanges 5 which are bent to form ball races 6. Between the. ball races 4; and (3 are placed balls 7. Tuwardly ol the ball races 6 the roller is provided with an annular flange or lip 8.

To lubricate the ball bearings a small. quantity of oil :11 is placed in each roller 2 before the roller is placed upon the spindle. the oil being; introduced through an opening 9 in the sleeve "i. The quantity oi? 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 oil level be ng such that when the spindle is tilted at any angle. the oil never reaches the lip 9. iv reason of the well-known tendency of oil to creep over a surface. sutlicicnt oil reaches the ball bearings to keep the latter properly luln'icated. than the cheeses are rotated. the oil a: is spread over the inner periphery oi the rollers 2. and when the cheeses are stopped some ot the oil creeps over the flanges 5 and the lips 8 and thus enters the bearings. The lip 8 increases the distance the oil must creep and thus reduces to the desired extent the amount of oil that reaches the bearinns. llhe amount o'l oil that reaches the bearings at any ,efiven stoppage is so small that the supply contained in the roller lasts for a long time.

The opposite ends of each' roller are slightly reduced in diameter to provide surfaces 10 for supporting the bearing flanges 6 of the cheese cores, these surfaces being connected to the remainder of the periphery of the roller by means of annular tapering shoulders 11'. By reason of such reduction in diameter the roller has a generally crowning form which prevents the cheese from moving laterally into contact with the adjacent cheeses when revolving in the creel, and restores the cheese to central position if displaced. WVhen' one of'the flanges 5* is on the highest portion of the periphery 01?;13118 roller, that side of the cheese moves a little faster than the other side, and hence the cheese is caused to cant, as a result of which the cheese moves sidewise as it revolves until both flanges Z) are again on the surfaces 10.

As shown in Fig. 3, the surfaces 10 on the adjacent ends of the rollers extend so close to each other that there are no gaps between the rollers into which the flanges b can drop.

The greatest diameter of the roller 2 is suificiently less than the smallest internal diameter of the cheese core so that the latter may be readily slipped on and off the roller by the operative.

In the construction herein illustrated, the spindles 1 are arranged in groups of three,

each group being fixed to an. elongated base 12. Thespindles 1 are secured to the base 12 by means of attaching members 13. Upon the outer end of each spindle is a tubular tip or cap 14 which, for convenience in manufacture, is rotatably mounted upon a sleeve 15, said sleeve having an outturned flange upon its inner end. The sleeves 3 are spaced away from each other and from the attaching. member 13 and the tip 14 by means of sleeves 16 having out-turned end fie nges which abut the flanges of the sleeves 3 and 15. The series of 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 Fig. 3, the ends of the rollers2 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 l't. In case some yarn should becomewound 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 is withdrawn.

, Each base 12 with its row of spindles 1 will hereinafter be termed a trident.

The tridents are adapted to be used at the winder as a'receptacle or a support for the cheeses when the latter are removed from the winder. When in use at the winder, the tridents restupon the bases 12' with the spindles 1 in upright position. l/Vhen in such position t-hecheese cores]; on a given spindle rest uponone another, as shown in,

Fig. 1. then the tridents are in use in the creel, the spindles occupy a horizontal position. lVhcn the warp-beam is revolved, thecheeses move laterally until each is properly located on its roller as shown in Figs. 1 and 3. As indicated in Fig. 1, when the trident is placed in the creel frame, the cheese nearest the tig of the spindle is so positioned that its bearing flanges b are both on the high portions of two adjacent rollers, and hence said cheese does not tend to move laterally, but the'cheeses nearer the base 12' push said cheese laterally until its bearing flangesare at different elevations, whereupon said cheese centers itself upon its roller. All of the cheese cores are thenout of contact with each other, as represented in Fig. 1. It will be seen that the cheeses need not be manually placed in running position upon their respective rollers.

The framework of the creel may be of any suitable character. For example, the framework may be composed of a plurality of bays each including a compartment adapted to support a plurality of tridents arranged one above the other as fully disclosed in Patent No. 1,207,138, granted De cember 5,1916. Herein only a portion of the creel frame is illustrated. At the left-hand side of the bay is a socket 19 to receive one end of the base 12- of a trident. At the righthand side of the bay are sockets 20 (Figs. 1 and 2) to receive the tips 14. Each bay is provided at one side with a gate 21 hinged at 22. The gate is held shut by means of a projection 23 on the gate adapted to lie in a recess 24 on a locking member25 fixed to the creel-frame. Each gate is provided with without giving any attention to the matter 7 of seeing that the yarn unwin'ds from the upper part of the cheeses. v

It will be apparent that the creel, comprising as it does tridents each ofv which is supplied with twelve cheeses atthe winder, may be filled and emptiedvery quickly, andwith a minimum of handling of thecheeses;

Suitable means may be; employed to arrest the rotation of. the cheeses when the warperstops. Herein I have indicated .inllig. 2 brake devices 27 located at the rear side of the creel-frame:andarranged to engage the peripheries of the yarn masses upon the cores 6, saiddevices beingsimilar to those spindles.

fully described in my copending application Serial No. 27,093, (Patent No. 1,207,138).

It Will be evident that the construction herein disclosed simplifies the handling of the cheeses and permits the cheeses to be rotated in the Warping process with a minimum amount of friction.

This application is a continuation in part of application Serial No. 781,919, filed July 30, 1913, and application Serial No. 27,093, filed May 10, 1915, (Patent No. 1,207,138).
