Application filed June 28, 1913.` Serial No. 776,237.

To all whom it may concern.'

Be it known that vI, HOWARD 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 Improvements in Creels, 'ot' which the following is a specification.

This invention relates to creels such as are used in connection with warpers or winders, the object of the invention, generally stated, being to provide a.' creel which may be operated at much higher speed than has heretofore been possible. The creel herein ldisclosed is especially designed for use in connection with thel warper described and claimed in my copending application, Serial No. 776,238, filed June 28, 1913. Said application discloses and claims the combination of means for obtaining a determinate amount of coasting of the cheeses or other individual yarn masses with means for obtaining a determinate amount ofv coasting of the warp bea-m. claims to the construction ofthe creel, the cheese brakes, and the means 'for operating said brakes.

Fig. 2lv is a side elevation of a portion of the brake-controlling mechanism. Fig.,22is a sectionV on line 22-22 of Fig. 21.

The embodiment herein shown of=the invention is arranged to operate upon yarn masses of ythe form termed cheeses, but it will be understood that thelinvention is not limited to use with such yarn masses.

A cheese (a Fig. 6) comprises yarn wound spirally upon a tube b (Fig. 13). The form of tube herein `disclosed comprises two sheet-metal sections, each consisting of a peripheral portion c, an .annular -end wall d and an inturned annular flange c. One of the peripheral portions o has a driving fit upon the other. 4.The flanges c fit tightly within a sleeve f.' The construction just described provides a lightftube of the desired internal' and external diameter.

The cheeses are rotatably mounted in a creel A (Fig. 1) positioned in front of the warper B (Fig..19). The threads g extending from the creel pass through a comb L (Fig. 20), thence over a guide roll i, thence through the detectors j and over guides 7c,

thence through a comb Z and over a guide roll m to the warp beam o.

The creel, in this instance, is a V-shape structure comprising two sections 1. Each section comprises a rectangular frame consisting of a lower bar 2, an upper bar 3, and uprights l. The creel sections may, if desired, be mounted on rollers yin order that when the cheeses have been unwound the sections may be quickly replaced with other sections previously loaded with cheeses.

Each creel-section comprises a plurality of trees 6 (Fig. 2) upon which the cheeses are supported for rotation. To facilitate the placing of thecheeses on the trees, the latter are mounted so that they may be turned from the operative position illustrated in Figs. 2 and 6 to a position at right angles thereto as represented'in Fig. 8. Each tree is composed of a bar 6a having at its lower end a pivot 7 mounted in a plate 8 on the frame bar 2, and provided at its upper end with a pivot portion 9 located in a bearing 10 in the upper frame bar 3. In the plate 8 is a shallow groove 11 (Fig. 9) to receive the lower end of the tree and hold the tree in operative position. To assist in holding the tree in place there is provided a coiled spring 12 that bears against a pin on the pivot 7 and the lower side of the plate 8. l

The cheeses are supported upon bushings or spindles 13 (Fig. 10) of wood or other suitable material. The spindles are each rotatably mounted upon a pivot pin 14 fixed to a guide sleeve15 slidably mounted on the bar 6a. A screw 13a having its inner end lying within an annular groove in the pivot pin 14 prevents longitudinal displacement of the spindles. All of the sleeves 15 on each bar 6a are supported by a bar 16 extending parallel with the tree and having vertically elongated openings 17 to receive lugs 18 (Fig. 12) on the sleeves. rlhe bar 16 is connected by means of a hanger 19 and a link 20 to one arm 21 of a bell crank lever 22 (Figs. 2 and 4). The series of bellcrank levers are supported above the top bar 3. The other arms 23 of said bell-crank levers are arranged to be moved by a rod 24 which is supported by the bell crank 22 at one end of the Creel-section and a bell-crank 25 at the opposite end thereof. The bell crank 25 is arranged to be moved by the warper, for a purpose which will presently appear.

In order to permit a determinate amount of coasting of the cheeses when a thread breaks, I provide braking means comprising polished metal plates 26 fixed to the trees in position to underlie the respective cheeses. )When the cheeses are to be braked, the bell cranks 22 are operated to lower the bars 16, thereby lowering the cheeses into peripheral contact with the plates 26, and thus braking the cheeses.

As hereinbefore indicated, the cheese-supporting sleeves 15 are loosely connected to the bars 16 by means of the lugs 18 extending through slots 17 in the bars 16. l/Vhen the cheese brakes are to be applied, the bars 16 are permitted to move down far enough to allow every cheese to rest upon its plate 26, but not far enough to bring the upper end wall of any slot 17 into contact with a lug 18, thus insuring that the braking pressure applied to each cheese shall be that due only to the weight of the given cheese and its which fact a large cheese is stopped with approximately the same amount of coasting as a small one. it any given time the cheeses are all about the samesize, and the amount that they coast is approximately equal. This would not be true but for the fact that the brake is a polished metal plate applied to the surface of the yarn; The rubbing of the yarn against the plate, in stopping, keeps the plate polished so that the surface condition of the plate remains very nearly constant. The other braking surface is the yarn itself, and as a new surface is constantly being presented (owing to the unwinding of the yarn) there is no change .in the characteristics of this surface due to wear; other changes due to such causes as temperature and humidity, aiect all the cheeses alike. On account of these circumstances and conditions the coasting of the cheeses, even when stopping from a very high speed, is nearly uniform.`

Means to be hereinafter described act to lower the cheeses as they are unwound, in order to maintain them at a uniform distance from the braking plates 26, and thus render substantially constant the time required to bring the cheeses into contact with said plates, and minimizing the shock caused by the fall of the cheeses. A series of'vertical thread-guiding bars 2T is stationarily supported at the outer side of each Creel-section, said bars being notched, as shown, to retain the strands in definite position.

The means for applying the cheese brakes when a thread breaks comprises two rods 28 (Figs. 2 and 16), connecting the bell cranks 25 of the'creel-sections with two bell cranks 29. The bell cranks 29 are pivotally mounted upon an arm 30 fixed to a shaft 31 (Fig. 1). rlhis arm is automatically adjusted in position for a purpose to appear hereinafter. The bell cranks 29 are connected by rods 32 to two arms 33 (Fig. 16) rigidly mounted on a rock shaft 34. Fixed to the shaft 34 is an arm 35 which is connected by a link 86 (Fig. 18) to an arm or bracket 87 loosely mounted on a continuously rotated shaft 88. Journaled in said bracket is a pivot pin 89 to which is fixed an arm 40 carrying 'a stud 41.

On a rock shaft 42 is fixed an arm 43 which is provided with a lateral projection 44 (Fig. 16) against which the stud 41 is arranged to bear. When the stud 41 bears against the projection 44 (as indicated in dotted lines in Fig. 18 and in full lines in Fig. 16), the bracket 37 is supported against the influence of gravity, thereby holding the cheeses off the brake plates 26.

When a thread breaks, the arm 43 is swung downwardly to carry the projection 44 out from under the stud 41, whereupon gravity causes the bracket 37 to swing downV into the position represented in full lines in F ig.- 18, the cheeses dropping onto the brake plates 26. The arm 43 is moved out of sup j )orting relation to the stud 41 by meansto be now described.

Fixed to the shaft 42 is an arm 45 (Fig. 21) which is connected by a rod 46 to a bell crank 47 supported on a stationary bracket 48. Attached to one arm of the bell crank 47 is a rod 49 carrying a nut and washer or otherI projection 50. The rod 49 is preferably screwthreaded for a considerable distance in order to permit adjustment of the' position of the nut. A weight 51 is slidably mounted on the rod 49. This weight is provided with a hanger which is normally supported by a rod 53. One end of the rod 53 rests on a bracket 54 and the other end is connected to an arm 55 fixed on a shaft 56. Also fixed to said shaft is a bell crank 57 (Fig. 19) arranged to be moved by a spring 58. The bell crank 57 is normally held against the force exerted by said spring by a lever or detent 59 having a stop shoulder 60 (Fig. 19a) against which the bell crank bears. Such, detent is arranged to be raised to release the bell crank by an electromagnet 61, the armature of which is attached to said detent. The electromagnet is energized whenever a thread breaks, which result is attained by the means to be now described.

Referring to Fig. 20: Each detector j is located in a vertically extending tube or conduit 62. Contact bars 63 carried by arms 64 fixed on shafts 65 normally extend within openings 66 in the tubes 62, into position to arrest any detector that may drop. Said contact bars are included in the circuit of the magnet 61. When a thread breaks, its detector drops into contact with the adjacent contact bar 63, thereby establishing a grounded circuit through the electromagnet. The bell crank 57 is thereby released to the action of the spring 58, whereupon the shaft 56 is turned clockwise as viewed in Fig. 19.

The rod 53 is thereby slid out of engagement with the eye of the Ahanger 52, whereupon the weight 51 drops. When the weight strikes the projection 50, it tilts the bell crank 47, the movement of which is transmitted by the rod 46 and arm 45 to the shaft 42. The arm 43 is thereby Withdrawn from the stud 41, whereupon the cheeses drop upon the brake plates 26, the bracket 37 assuming the position shown in full lines in Fig. 18.

The brake (not shown) for the warp beam o is applied by the movement of the shaft 56 caused by the spring 58, as fully explained in my said copending application. In the present embodiment of the invention, it is desirable that the application of the beam brake occur before the cheese brakes are applied, hence the use of the weight 51 to Awitlnlraw the cheese brake detent 43. The length of the interval between the application-of the beam brake and the application of the cheese brakes may be regulated by adjusting the projection 50 on the rod 49. 1 would have it understood, however, that other means may be used to cause application of the cheese brakes after the beam brake has been applied and that in other embodiments of the invention the beam brake and the cheese brakes may be simultaneously applied.

The shafts 65 are connected by gear segments 67 (Fig. 20). To one of said shafts is fixed an arm 68 which is connected by a rod 69 to a Crank arm 70 (Fig. 21) on a shaft 71 which is alined with the shaft 56. On the shaft 56 is an arm 72 carrying a pin 73 that underlies an arm 74 fixed on the shaft 71. It will be seen that when the shaft 56 is turned to apply the cheese brakes, the contact bars 63 will be withdrawn from the openings 66.

As explained in my said copending application, the beamecontrolling brake is designed and adjusted to permit a little less coasting of the beam than the cheese that coasts the least. The resulting slack in the individual threads is taken up by the descent of the detectors j in the tubes 62.

When the contact bars 63 are moved out of the openings 66, the detector belonging to the broken thread drops through its tube into a receptacle 75 (Fig. 19).

After an application of the cheese brakes, the shaft 56 is reset by means of a hand leve1z77 (Fig. 19) pivoted at 76 and engaging a link 78 pivoted to the bell crank 57. The parts 77 and 78 are united by a pin-andslot connection, so that the bell crank 57 may move under the influence of the spring 58 without moving the hand lever. After the machine has stopped by reason of thread breakage, the operator uses the lever 77 to restore the bell crank 57, the shaft 56, and the rod 53 to normal or running position. The operator then raises the weight 51 and engages the hanger 52 with the rod 53. As soon as said weight is lifted, a weighted arm 79 (Fig. 18) fixed on the shaft 42 turns said shaft into normal position, thereby placing the arm 43 in normal position. Fixed on the shaft 42 is an arm 80. )When the shaft 42 is tui-ned into normal position, the arm 80 strikes a pin 81 fixed to a pawl 82, said the movement of the pawl into engagement with said wheel. As soon as the pawl engages the wheel, the latter swings the arm 37 up into normal position as shown in full lines in Fig. 16. As the arm 37 approaches its normal position, the pin 81 rides up on a stationary cam plate 86, whereby the pawl 82 is withdrawn from the ratchet wheel, and the stud 41 is placed in position to stop against the projection 44. In the movement of the arm 37 from the thrown-out position shown in full lines in Fig. 1S to the normal position represented in Eig. 16, the bars 16 are raised to lift the cheeses olf the plates 26.

The warp beam 0 is rotated by a rotatory drum S7 (Fig. 19) which has peripheral contact with the yarn mass on the beam. The beam trunnions are engaged by bearings 88 formed on slides 89 that move upon the upright frame members 90. The drum 87 is fixed upon a shaft 91 arranged to be driven by any suitable means, such, for example, as that shown in my copending application. The driving means shown in said application is arranged to be automatically thrown out, and the beam brake and the cheese brakes applied, upon the breakage of a thread. The shaft 38 may be driven in any suitable way as by intermeshing gears 92, 93, the gear 93 being fixed to the continuously driven pulley 94.

ln order to automatically adjust the position of the cheeses as they are unwound, so as to maintain them at a uniform dis tance from the brake plates 96, I provide the means to be now described.

A roll 95 rests upon the yarn mass on. the warp beam o and is of sufficient length to extend from one end flange or head of the beam to the other. (1n Fig. 19 a portion ofone flange of the beam is broken away to show the roll 95 in end elevation).

The roll 95 is controlled or guided -by means of yokes 96 attached to a bar 97 which in turn is fixed to slides 98 vertically slidable on the upright frame members 90. (See Fig. 1). One of the slides 98 is connected. by means of a link 99 to an arm 100 fixed on a rock shaft 101. Rigidly mounted on said shaft is an arm 102 which is connected by a rod 103 to the arm 30. lt will be seen that as the cheeses are unwound, the yarn mass on the beam increases in diameter, and the roll 95 rises, thereby lowering the arm 30 and thus lowering the cheeses, so as to maintain them at a substantially uniform distance from the brake plates 26. The length of time required to bring the cheeses into Contact with the brake plates is thus rendered approximately constant, and excessive shock due to the fall of the cheeses is avoided.

When the creel sections are to be withdrawn for replenishment, they may be disconnected from the warper in any suitable way, as by removing one of the pivot pins of each of the rods 28.

I would have it understood that the invention is not limited to the precise arrangement of parts herein shown, the embodiment illustrated herein being susceptible of considerable modification.
