' ..comprisinga creelthat embodies the features of my. invention.

Fig. 2 is a fragmental side elevation of the ..creel.

Fig..-3 .is agfragmentaliplan view of the creel. Fig; 4 is a frag-mentalelevation. -Referring to.-Fig. 1:. Aydenotes a warper which v :20 maybe of any preferred characterand B is a creel embodying the .features of my invention.

.While-thecreel may. beof various. forms,.I have -herein shown it:-as comprising two upright frames 1 hand; 2-.which.are adjacent each other at the end 5lnear theiwarper and separated from each other at the opposite end so as to forma V-shaped "structure. :Eachframe comprises means for sup- :;porting. andcmovingan endless series of yarn- .mass carriers.

lReferringnoW toFigs. 3-and 4: 3 denotes an upright bar. toone side of which is attacheda columnor vertical series 'of yarn-mass supports 4. .These supports may beof any desired nature =-.,appropriate..to the character, of the yarn masses :35. to be supported. In the present drawings, I have shown. cross-wound yarn. masses or cheeses a,- formed uponcores b, the .bar 3 being provided with devices 5 which non-rotatably support the 1 cores with their axes in horizontal position. Survv40 rounding each yarn mass a is a cylindrical casing 6 having a. closed end I which is rigidly secured to the bar 3;:the opposite end of the casing being .:open for the insertion of full cheeses and the removal of cheese cores. The casings 6 enable the 45 ballooning yarn to set up air currents that blow .:the lint out toward the front of the creel and thus :prevent lint from accumu lating on the yarn masses. The casings also serve to keep the ballooning threads out of contact with one another. .60 As shown in Fig. 2, the yarn-mass supports 5 and the-casings 6 onone bar 3 are staggered with relation. to the supports and casings on the adjacent bars, so. as to economize space.

Attached to theupper end of the bar 3 is a ;5 l -roller v8. which .is. arranged. to .run upon. a. track member 9- that is secured in the upper portion of the vcreel frame. Said roller is located {at the outer side of the bar 3.

The bars '3 are secured together to form an endless series by means of two flexibleelements herein shown as chains and II secured to the inner sidesof said bars near the upper and lower ends thereof. Each chain extends around sprocket wheels l2, I3 and I4 mounted in the creel framework for rotation upon vertical axes. The two driving sprocket wheels l2 are fixed upon a shaft I29, the-sprocketwheels I3 and I4 being idlers. The lower chain II is arranged to run along guide flanges I (Fig.4) in. the creel frameat points between the sprocket wheels.

A guide plate [6 is secured to the upperend of each bar 3 to extend inaverticalplane, the lower edge of said plate being arranged to move in close proximity. to theinner-edge of the track 9 and the upper edge of said plate I6 being arranged to travel in close proximity to the..outer side of a guide flange l'I fixed in the creel frame. It will be seen that the-series of plates l6 serve to prevent the upper chain In from moving out of a substantially straight line between the sprockets I2 and I3 and between-the sprockets l3 and I 4 and betweenthe sprockets l4 and I2. The plates I6 also prevent the bars 3 from swaying on the chains and thus hold the yam-mass supports 5 stationaryduring warping. That porhaving on its armature shaft a pulley 2| from which power is communicated through a belt 22 to a pulley 23 fixed upon-a shaft 24. On each end of the shaft 24 is fixed a bevel gear 25 thatv meshes with a bevel gear 26 that is fixed to one of the sprocket wheels l2. Any desired or conventional means may be provided for starting and stopping the motor and for running it at the desired speed.

-At the outer side of each of the creel frames I and 2 is located means for guiding the yarn from the cheeses to the warper. If desired, ,means may be associated with the yarmguiding means for detecting exhaustion,v breakage or ex- .43 tion of the inner edge of the track9 which is 10 purpose comprises an electric motor 20 (Fig. 1)

cessive slackness of the yarn. The means herein shown for this purpose consists of vertical tiers or columns of yarn-guiding and detector units 21 similar to those described in my Patent No. 1,790,318, dated January 27, 1931, to which reference may be made for a full disclosure. The spacing of the columns of yarn-guiding units corresponds to the spacing of the bars 3, there being one unit in axial alinement with each cheese which is in running position.

The mode of operation is as follows: Assume that those bars 3 which are positioned at the outer side of the creel frames 1 and 2 are provided with yarn masses, the yarns of which are guided to extend to the warper. While those yarn masses are being unwound, the operative places yarn masses upon all of the other bars. When the yarn masses at the outer sides of the creel have been unwound completely or to the desired extent and have been disconnected from the warper, the operative operates the motor 20 to cause the series of yarn-mass supports to move in the direction indicated by the arrows in Fig. 1, whereby yarn-mass supports carrying full cheeses are brought to the outer side of the creel and the yarn-mass supports with the emptied or substantially empty cores are brought to the inner side of the creel. When the full cheeses have been brought into approximately unwinding position, the operative runs the motor intermittently so as to inch the series along until the full cheeses are in axial alinement with their respective yarn guides. The yarns of the full cheeses are then connected to the warper and warping resumed, after which the operative proceeds to remove the empty cheese cores and substitute full cheeses.

It will be seen that the construction herein disclosed greatly facilitates the reloading of the yarn-mass supports, that the time required to replace (in unwinding position) unwound cheese cores with full cheeses is reduced to a minimum, and that the operation of bringing full cheeses into unwinding position requires no appreciable physical exertion on the part of the operative, as all that is required is the operation of the electric motor 20. It thus becomes possible to reduce to a minimum the time the warper is idle.
