7 j A TTORN'EY Patented July 18, 1933 UN'ITED'STATES PATENT I E-1 LOUIS OSKOW, or BRooxLYN, NEW YORK, assmnon TO BARL O nnemnnlimo-oo. inc, or LONG ISLAND CITY, NEwYoRK, A'CORPORATION WINDING MEC ANISM Application. filed Janet, 1930, Serial No.459,0521. Renewed ariam.

This invention relates to windingmechanism. It is directed to a creel mounting a plurality of bobbins" from which threads are fed to-the warp beam in the usual manner, and contemplates the provision of signal means forindicating the tearingor breaking of one or more threads passing to said beam and the particular bobbins from which said torn threads wereunwound. The operator may thus be. quickly apprised of the factthat one or more of the threads are broken so that the further operation of the machinery may in'miediately be stopped and the broken threads mended, thus obviating the necessity for reversing the operation tounravelaconsiderable length of the threads.

An objectofthis invention is to-provide in mechanism of the Character described, wherein the bobbins are mounted in rows,

means for indicating the row in which thread fromone of the bobbins has broken, and

means for indicating the particular bobbin in i said rowlmving the broken thread, and furtheir mastersignal means for indicating when any thread on the entirecreel has broken.

In windingapparatus now in use, the warp beam to which the threads from the bobbins are fed, is usually; stopped as soon as a break of anywof the threads is discovered andthe rotation of said wheel reversed, to permit mending of the broken thread, thus causing slack of the threads often resulting inlen-f tanglement thereof, and usually diificultto unravel or undo. It is accordingly, a further object of this invention to provide means for automatically stopping the rotation of the warp beam as soon' as any thread has been broken, whereby entanglement of the'threads is effectively prevented. a

Another object of this invention is to provide in apparatus of the character described, means for preventing operation of the signal means when the warp wheel is idle and the threads are not being unwound from the bobbins "so that the signal system is only operative when the warp beam rotates and the weaving machinery is inuse, said means further being arranged for permitting the signal indicating the row having a bobbin, with a broken thread to remain in signalling ,inm' v t I Fig. 5isa view similar to Fig. 4, but showing the. position of the condition even when the warp wheelhas stopped rotating upon breakage ,of I said thread, the'signal indicating theparticular bobbin with the broken thread likewise remaining in indicating position until returned. manually to, normal position. v i

Still another object of this invention is to} I provide apparatus of the character described,

which shall be comparatively simple ,a'ndinexpensive in construction, pos tive in'opera 'tion and practical and eflicient to aihigh degree 1n use. g

Other objects of this invention will inpart be obvious and. in part hereinafter/pointed out; v The invention accordingly consists in ,the features of construction, combinations of elements, and arrangement ofIparts which will be exemplified in the construction hereinafter described, and of which the scope of appli-' l cation will claims.

designates a metal creel mounting, as. hereinafter described, a plurality of bobbins 11 feeding thread to a rotating warp beam. 12

usuallyjmounted adjacent and above the creel. The creelsnow in use usually are constructed for supporting a large number of bobbins ar iranged in a plurality of closely/adjacent 70 a v be indicated the following j;

" 5 tion'30 bent at right angles to saidportion rows. For the purpose of illustration only,

four vertical rows having four bobbins in zontal cross bar 16. For rotatably supporting the bobbins 11, there is provided a plurality ofhorizo ntal rods or pins 18 attached to the backing member 17in any suitable.

manner and projecting forwardly therefrom. The pins 18 are preferablyarranged in a number of'vertical rows. Mounted on each ofthe rods 18 at a point thereon adjacent to andsomewhat spaced from the backing member l 7,-as by spacers 17a, is a fixed bushing 20 made of electrically insulating material and comprising atubular member 205; received on said rod and a vertical flange 20?) adjacent the spacing member 17a. Mounted on the tubularportion 20a of the bushing 20 is a tubular metal sleeve 22 preferably made of coiled wire construction and having an arm 23 extending outwardly therefrom for the pur pose hereinafter appearing. I v

f Rotatably mounted oneach of the rods 18 adjacent the bushing 20' is a centrifugal switch mechanism 24. Said mechanism24 comprises a' tubular inetalsleeve 25 rotat-' ablyreceived' on the fixed, rod 18 and a disc 26 extendingat right angles to the sleeve portion Pivotally mounted on the disc 26 as on pin 27 at an eccentric point on'said I disc, is an arm 28 comprising a plate portion 29 lying 'flat against the disc 26 and a por 29. The disc 26 is provided with an outwardly extending portion 31 adapted to limit the outward rotation of said arm'28 and with a second outwardly extending portion or lug .32 to which is attached one ,end of a small tension spring33. The opposite end of the spring 33 is attached to a lug 34 extending outwardly from the plate portion 29 of said arm 28 whereby the spring 33 normally tends to rotate said arm 28 inwardly or to- Ward the rod 18. Integrally-formed with said plate portion-29 is a projection35 extending at right angles therefrom and adapted to contactxthe sleeve22 uponbeing r0- tated inwardly toward the rod 18 by tension spring 33. f Y

It will now be noted that when the arm 28 contacts the sleeve 22, said sleeve which I is mounted on the insulating bushing 20 is electrically connected to the rod 18 and from which the thread 1 be attached to the disc 26 for rotation therer with by means of interengagement of pins. or lugs 38 integrally formed with the disc 26 and received within openings 39 formed in the end wall 40 of the bobbin 11 adjacent I said disc. I It will now be, noted that when the bobbin rotates in the direction of the arrow shown in Fig. at, as the thread therefrom is being unwound by the rotating warp wheel the switch mechanism 24 rotates with said bobbin and the arm 28 by reason of centrifugal. force rotates or flies outwardly away from- -the rod and hence breaks contact between the projection 35 and'the sleeve 22. In this manner; electrical connection between the sleeve 22 and the ground, is broken. "It will be noted also that during rotation of the bobbin, air ,pressure against the portion 30 of arm 28 will aid in causing the said arm to fly outwardly to break the contact.

It will now be .understood that each of the rods 18 is provided with switch mechanism 2 1 and the bobbin ll and with the threads 37- unwinding from the bobbins, extend upwardly andover the roller 11 suitably supported at the top of thecreel-frame and to the rotating warp beam12 in the wellknown manner. Rotation of the warp beam 12 obviously pulls the threads for unwindmg the freely rotating bobbins during the winding operation. As long'as the threads are being unwoun'd' andj remain unbroken,.

the bobbins ll'will continue rotating and the arms 28 will remain in an outwardly swung position as shown at Fig. 4 and hence the electrical connection between the sleeve 22' and the ground will remain broken.

However, when the thread 37 from. any bobbinbreaks, the speed of rotation of the'bobbin from which said thread was unwinding will decrease and the bobbin will then gradually stop rotating. Upon decrease of the speed below a predetermined point necessary to maintain the arm 28 in the position shown in Fig. 4, the spring 33 will pull said arm into contact with the sleeve 22 for closing the switch.

It will now therefore be obvious that'the switch mechanism 24 for any bobbin will be closed automatically upon the event of 32 and normallyurging said arm toward the sleeve 22. 7

Signal means is provided for indicating which switch has been closedyin which row a switch has been closed, and alsowhen any switch on theentire creel has been closed. To this end there is a lamp '50 mounted adjacent each vertical row of bobbins, preferably fixed on the top cross member16. Su table electro-m'agnetic annunciators 51 of the type having a swinging plate adaptedto drop upon energizing the magnet thereof, are provided for each bobbin, said 'annunciators and bobbins being correspondingly numbered. The wiring for the annunciators 51 and lamps 50 are illustrated by diagram shown, in Fig. 1 of the drawings.

Each annunciator is connected'by wiring 66 to the arm 2-3 of the terminal 22 for the bobbin corresponding thereto. The annunciators 51 for each row are connected in parallel electric circuit to each other by WIN Hg 51a and in series circuit with the lamp 5 0 for said-row by wiring 52. The lamps 50 are connected in'parallel with each other and a from the electrical power "source 53' thru in series with a suitable electric power source 53 by wiring 55. Said power source-53 is connected by wiring 56 to'one terminal 57 of a switch, the other terminal 58 of which is connected means of wiring 59 to the'backing frame 10 which acts as aground for the centrifugal switch mechanism 24-. Thus, when the fixed spaced terminals 57, 58 are interconnected by the switch arm 105, hereinafter described, the power source 53 is grounded to the backing member 10fand hence to each of therods 18.

It will now be understood that when the thread from any bobbin has broken, the

speed of rotation of said bobbin is decreased and the-arm 28 of the switching mechanism for said bobbin contacts the-sleeve 22 for completing the electrical circuit thru'theannunciator corresponding to said bobbin and thru the lamp for the row in'which saidlbob bin is located. The current may the'n pass wires 56 and 59, to the ground 10, thru the rod 18, switch arm 28, sleeve 22, and-wire 66,

thru the annunciator forenergizingthe electro-ma'gnetthereof and causing the numbered plate to drop for indicating the bobbin with the broken thread. The current ner so that the broken thread may be "mended.

Rotation of the warp beam- 12 is usually controlled by a beam which in any suitable 11121-111181 operates a clutch (not shown) lorclutching the warpwheel in or out withrespect to a suitable rotary -,membei"o ierated by motor means (not shown). Thus, when I a the beam 70 is in the downward position as shown in Fig, 1, the warp beamis clutched to itsmotor means and is hence being rotat ed. For retaining the beam 70 in position for operating the warp beam 12, there may be provided a member pivoted at the low er end thereof to anyfixed member such as j the floor 76. Said member 75 isprovided with a hook portion 77 adapted to engagea resilient pro ection 79 fixedjto one end of the beam 70. Said member 75 is furthermore provided with an upstanding projection 80 having a curved orcammed'surface 81 on the side thereof adjacent the projection? 9. It will thus be seen that the pro-- jection 80 .se'rvesas the means for releasing th'ebeam, the same being. ada'ptedto be engauged by theoperators foot, for disengaging the hook from the beam for declutching the warp wheel and stopping operation thereof. Upon moving the beam'70downwardly to again cause rotation of thewarp I I beam, the spring projection 79, contacts the curved surface 81 of member 75 for pivotalj 1y moving the llatterto permit said "movement of the beam, Compression. spring 82 serves in the manner hereinafter appearing,

to snap the member 75 back to its normal position after the. beam 70 has been moved to its lowermost position. Means'is provided for of the warp wheeljmay be automatically I automatically hooking the member 75 upon breaking of the thread on any of the'bobbins so that rotation stopped as soon as any thread is broken and v thus obviating the necessity for reversing dij r'ectionof rotation of the warp beam as usually: necessary with Winding apparatus now' in use for mending the broken thread.

To this end there is interposed in said wiring an electro-magnet adapted .to attract when energized a switcharm 91having th ere: one contact member92. tl Vhen the arm 91 is attracted by the .magnet90 the contact 92 is adapted to'contact a fixed terminal 93'con nected by wiring source 95. Said switch arm 91 is normally unaintained' out ofcontact with respect to sai d terminal- 93 by any suitable means, such as spring 96. Sand switch arm 91'is prefer- 94- to a suitable. power.

iii-5 ably made of electrical conducting-material and 1s connectedby wiring 97 to a relay 98, p

thelatter being connected by-wiring 99 to said power source for completing the.

circuit.

It willnow be seen thatwhen the 90fis=energized, upon the breakage of any oi the threads. the circuit thru relay 98 is automatically closed. Saidrelay 98 is ad anted to actuate an armature 100 connected by arni 101 to the pivoted arm 75. p The compressionspring 82 for maintaining ltheswitch arm 75 in; normal hooking position shown in Fig. 1, may bemounted on the armature 160 and isipreferably interposed-between the relay 98 andaiiange 102fiXedto one end of' d armature. Obvimisly, when the arma- .'ef1OO is attracted it will compress the e threads f ormending, 1S

threads is a from re beam unravel-th 1 for an tam a ti cal lyv cuttern except the lit lamp 5- litzuirm slu arulautomatic lly with the event of a broken threadand the stopping of the rotation of the warp beam; so that the s alirrimerative whenever n w i in is 'ale and the centrifiugul s .viich-:,. drop into contact with terminals 22. To this end the switch arm 105 is conncc .(l h arn .70 and is adapted to iinals .3? "nil id-unify. n F0 1.. in its low. a mostposition shown in Fig.1. lVhen a thread has broken and the beam iin ti ed to me upwardly, above, for storming switch arm 105' will likebrcak the circuit thru the it; and hence the electrical ciraround 1 and aiuiunciators 51 121 by closureof the ch ari tor will drop and I eatingposition until moved up dly manually in the well known n: nfer. Thus, even 1 thru the z. nunciatr has been it out, the annunciatm" which by *ason of the broken th ead W1... n1. n in Qnalling' position.

Means is provided however, for retaining the lamp in the row having the bobbin Wlilll has been acts the broken thread insignalling position even,

when the circuit thru the ground 10 and anthe wire 52 leading to each. lamp is directly connected as at 110 to an electro-magnetlc core 111. A shunt '1152'is coiled about the core 111 and is aiso connected directly to said core and to the wiring; 52 as at 110. It will thus be seen that when any thread has broken and the centrifugal switch mechanism for the bobbin having the brokentl'iread has been moved to closing osition for coniplcting the circuit thruthe lamp 50, the shunt 112 which is connected in parallel tothe lamp 50 will also receive current for magnetizing the core 111. Each core 111. is adapted to at tach a switch arm 114 made of conducting material and adapted "to directly contact-the v therewiththe arm 75.

the same ate for said ann uncia- 'n'al indinunciators 51 hasbcen broken. To this end core upon being attracted. Saidswitch arms 114 are interconnected by means of wiring 115 in parallel circuit and are further connected bywiring 116 in series circuit with said power supply 53. A master signal means 117, such as a lamp or the like,may beinterposed inthe wiring 116. Ahand switch 118 may likewise be interposed between said wiring 116 for the purpose hereinafter appear 1 ing. v

It will ,now beunderstood that when the thread of anyqbobbin has broken the core 111 in the rowbeing said bobbin is energized for attracting the switch 114 and hence connecting the lamp 50' for said row in series withthepower supply 53 by means of wiring 115, 116 and 55; Thus, although the switch 105 when moved upwardly with the beam 70 the broken thread. The annunciator for the bobbin having the broken thread will also indicate the bobbin corresponding thereto until the plate thereof is moved upwardly, as is well understood. v With this construction therefor, although the warp beam is stopped automatically upon, breakage of any thread i and all of the bobbins hence stop rotation to permit closing movement of the switching arms 28, the slgnalhng means nevertheless will not be actuated, byreason of the open circuit thrutheground 10. i v

. It will now be understood that when any thread breaks, the annunciator, correspondingthereto is actuated, the lamp therefor is illuminated, thewarp beam is automatically stopped, the-rest of the signalling system is deenergized, andthe masterlamp 117 is also illuminated. I Obviously, the hand switch 118 must be closed during this-operation;

, For permitting opening of the switch arm 114, which has been moved to closing position, under the infiuenceof the energized core 111, there is provided a circuit breaker 120 interposed in the wiring 55, preferably in the form of an ordinary, push button switch which merely need be pressed once for completely deenerglzing the entire. signalling I system. r

I When a broken thread has been mended, thebeam 70 may again be moved downward 1y toward the position shown in Fig. 1 to start rotation of the warp beam and hence unwinding of the bobbins which are thereby rotated for causing the switch arms 28 to fly outwardly. Preferably, the beam 70 upon being movedoutwardly causes rotation of the warp beam 12 before the same is at its lowermost positionso that the bobbins may be rotatmg and the centrifugal switches open before theswitch 105 closes the contacts 57 58. With said construction, when the circuit thru the ground is closed by means of the switch 105,

the circuits thru the annunciators and lamps will be open until a thread breaks.

It will further be understood that when the relay 98 is energized upon breakage of a thread, the pivoted arm 75is moved to the right, looking at Fig; 1] Upon movement of the beam however, upwardly'to stop rotation of the warp wheel, the switch 105 breaks the circuit for electro-magnet 90 thus releasing switch arm 91 under influence of spring 96.- This action automatically deenergizes relay 98 and permits return of core 100 and hook arm under influence of com? pression spring 82, back to the position shown inFigl. V i 7 It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meetthe conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense,
