' YARNWINDING APPARATUS.

Application filed November 23, 1926. Serial No. 150,185.

This invention relates to winding appato support the control instrumentalities for rat-us of the kind wherein yarn ends are drawn from individual supply packages in a supporting creel, and wound as a continuous sheet with the aid of a beam warper upon beams for convenience of transferv to looms or other textile machinery for further processing. Such beam warpers are ordinarily equipped Vwith automatic mechanical stop mechanism controlled by broken yarn end detecting means located close to the beams on which the yarns are wound. Under these conditions, it is impossible to effeet stoppage of the warper before a broken end is taken in and lost on the beam; or, in other words, by virtue of the location ofthe detecting means aforesaid, there isnt avail.

able a sufcient reserve length of the yarn tosatisfy overrun of the beam resultant upon sudden stoppage, particularly in view of the tardy action of the linkages, etc., lbketween said detecting means and the stop mechanism,

The present invention is, in part, directed toward overcoming the diiculties pointed out by provision, for maintenance, before the creel, of a reserve length in the yarns capable of compensating for the overrun of the warping beam incident to automatic stoppage of the apparatus with insurance.

against the loss of the broken end yor ends'.

A further obj ect ot' my invention is to improve the cooperative action between the stop mechanism of the warper and the coorf dinated yarnengaging stop control to the end of securing theabove desideratum withl increased speed of the apparatus and correspondingly greater productive output.V

Still another object is to provide for lateral distribution oi' the yarnsv incident to their passage between the supply creel and the warper such that any defective or broken ends may be easily observed and repairs readily` made without inconvenience to the operative, and for the further purpose of promoting ready mergence of the yarns into one continuous sheet at the warper. Y In the drawings, Fig. I shows more or less diagrammatically, the plan view of a yarn winding apparatus conveniently einbodying my invention.

Fig. II is a side elevation of the organization shown in Fig. I.

VJit-h more Vdetailed reference to these i-llustrations, 10 indicates comprehensively, the generally speaking, is,

trip means 18, which, when actuated, allows a spring 19 to draw theshipper 20 for trans fer of the driving belt 21 from the tight pulley 22 to the loose or idler pulley 23.k I`he trip means 18 may be of any approved design, for example, a latch bolt 25 retractable against spring or gravity influence vfrom normal engagement with a lug 26 on the belt -shipper rod 27 by means of a solenoid such as conventionally delineated at 28in Fig. I.

lThe creel, generally designated by the numeral 80, is longitudinally aligned with the beam warper 10, but spaced therefrom by a liberal interval as shown. vThis creel 30 is oi' the sort known in the textile art as a"magazine creel, with its wing sections 31V disposed to opposite sides of the longitudinal center of thel apparatus, and .coinplef mentarily adjustable angularly to suit various conditions of practice. vEach such creel wing section 31 stationarily supports a multiplicityoil yarn packages or cones 32 arranged in vertically-spaced horizontal rows and grouped in .pairs whereof the two components have their` axes convergent relative to common yarn guides 33 located at the focal point. By tying the. leading end `of thereserve cone 32 to the trailing end of-its active companion, it Will be apparent that a continuous supply of yarn may be had by successive y substitutions, when the reserve cones become exhausted, Without necessitating stoppage of the apparatus. The Vuseof a `creel 30 of the described type is favorable in the present connection, firstly, because it r 2 Y Levi-i975 the packages or cones are individually rotated bodily by draft induced in the yarns. lt is however to be understood that other types ot creeis 3() may be employed in con` nection With my invention it desired, or it any special conditions of mill operation should Warrant or require it.

is means to guide the yarn ends en route trom the creel 30 to the beain warper 10, l provide, in accordance with my invention, supplemental boards 35, associating one such with each ot the creel'ivings 3l. These boards are sustained in a vertical. position, contiguo-us to the i'ront end of the creel 30, with capacity for relative adjustment transversely of the apparatus in the interval between said creel and the Warper 30, by means of positionally lined upper and lower channel guides 3G, 37. ln their construction, the boa-rds 35 comprise trames 38 that periinetrically .engage and sustain inset panels 39 of insulate material; and, levels corresponding to the elevations ot the several horizontal yarn pac `rage roi'vs inthe creel 80, said `boards are equipped with transverse lines et uniformly-spaeed guide eyes 4() through which the yarn ends from Vthe respective rows of cones 82 areV led and incidentally distributed laterally 'for niergence subsequently into one continuous sheet in rounding the guide rods'4l, 42 in advance of the leading reed 43 olf the ivarper l0. ln order to facilitate access to Yopposite sides or' the boards .35 for the purposes ot ready threading, elongated horizontal openings -are provided bet-neen adjacent rows of the n eyes 40, see lll and lV. "itt the back,

and beneath each row ot guide eyes theV boards 35 are 'further equipped `with serially` arranged electric stop control instrumentalities llia-to a corresponding number which are ulcrumed upon a common pivot rod 46 supported by a bracket plate 47. These control instrumentalities are preferably fashioned to the angular conliguration shown in Fig. V from stout Wire, with loops at their outer ends t'or suspension individually by the yarns inan interval between the guide fifi eyes 40 and a directional guide rod 4S. lVhen released consequent upon yarn break age7 the controls 45 drop to the dotted line position shown in l! ig. V, thereby electrically bridging the bracket plate 47 and a spaced parallel contact plate'49 immediately 'therebelow. As shown inFigs. lll and lV, the bracket and contact plates 47, 49 of the sev-V eral. groups of controls 45 are respectively connected in parallel by conductor vstrips 50, 51 that entend to terminal posts 52, 53 at the fronts of the boards 35.

The opera-tion of the apparatus is as follows: wWith continuous movement of the driving roller l1 in the beam Warper l0, the yarns areeontinuously drawn troni the ereel 30 and Wound upon the driven bea-in 16. Iniinediatelyupon rupture of one ol' the yarns at the creel 30, the corresponding electric control 45 eii'ects closure of the circuit through leads 54, 55 (Fig. l) and energization of the solenoid 28, which actuates the trip means 18 associated with the stop meehanisin 17 of the Warper l0, thereby causing stoppage of the apparatus with current supplied by conductors 56, 57 extending trom a suitable source of electricity, not shoivn. lAs a consequence oit the uniform separation and lateral distribution of the yarns at different levels by the boards 35, Vthe usual `ditliculty ot' locating broken endsris obviously entirely avoided. Moreover, the liberal spacing oft the Warper l() and tliecreel 30 `when taken in connection with the'allocation of the stop controls 45 on theeye boards 35 in close proximity to the creel 30, provides an ample reserve before the Warper l0 so that the apparatus can be safely operated at high speeds without danger ofthe broken yarn ends be` coming lost on the Winding beam 1G ineidentally to sudden stoppage, in the manner hereinbeiore explained.
