QUILL-WRAPPING MACHINE.

Application filed May 13, 1918.

To all whom it may concern:

Be it known that we, JEAN Josnrns and DAVID Tnnononn BERLIZIIEIMER, both citizens of the United States. and both residents of the city and county of Philadelphia, State of Pennsylvania, have jointly invented a new and useful Quillrapping Machine, of which the following is a specification.

()ur invention relates in general to winding machines of the ordinary spool-winding type in which it has heretofore been customary to take the threads from skeins mounted upon revoluble swifts and first wrap them upon spools and thereafter wrap them from the spools upon the cop-tube, bobbin or kindred tubular or other carrier, which when 'wrapped with the thread will possess the ultimate form of a, so to speak, doubly conical Wrapped product known in the art as a quill or cop.

our principal object is to so reorganize or reconstruct a typical spool-winding machine as to make it adaptable without the intervention of spools, to wrap a thread upon the cop-tube and form the ultimate cop or uill, by taking the thread directly from the skein.

Our machine is adapted to wind or wrap a thread, whether of silk, artificial silk, cotton, wool, or other fiber, directly upon a cop tube from a skein, and thereby, as stated, completely eliminate the intermediate operation of winding from the skein to the spool,with the result that our machine it self is exceedingly compact, takes up but very little floor space, and may be operated to the production of a large number of quills at a minimum of both power and labor costs.

A further object of our invention is to make our machine automatic in the sense that if in the course of the winding of any particular quill the feed of the thread should in any way be stopped. such mechanism of the. machine as relates to the feeding and the winding of the thread, will be automatically stopped and when again started will continue its work without leaving marks of identification upon the cop or quill where the stoppage has occurred. and without, therefore. turning out imperfect cops or quills. The result of this capacity is that Specification of Letters Patent.

Patented Mar. 25, 1919.

Serial No. 234,112.

the machine may be operating continuously as to given quills and yet not be operating as to a particular quill the thread of which has in feeding been broken, until after the thread has been repaired.

Further objects are a simple and compact construction of the elements which in their assemblage constitute our machine, and a general organization which permits of the winding of a very large number of quills.

The special features in which our invention is embodied and which constitute its essential subject-imitter, are specifically recited in the claiming clauses. Broadly considered, however, our invention comprehends an automatic machine in which a plurality of cop-tubes can be wound with thread drawn directly from the skeins without the intervention and operation of winding upon spools,which latter are dispensed with, and in which in the event of the breaking of any one of the threads from any one of the skeins, the operation of the winding of that particular thread upon its particular cop-tube is automatically stopped until the broken ends of the thread are united, and thereafter is automatically started again to complete the cop the winding of which has for the time being been stopped.

The invention further comprehends an organized machine in which the formation of the thread upon the cop-tube into a cop of double conical form. is uniform and accurate by reason more particularly of the accuracy and regularity with which the thread is caused to be presented to and wound upon the cop-tube.

For the purpose of illustrating our invention, we have shown in the accompanying drawings a certain type and embodiment of it which is atpresent preferred by us because in practic it will give satisfactory and reliable results.

It is to be understood, however, that the various instrumentalities in which our invention is shown as embodied can he variously arranged and organized. and that our invention is not therefore limited to the precise arrangement and organization of the instrumentalities typified in the construction shown in the accompanying drawings and hereinafter described.

In the drawings, a sufficient representation of a double machine is made to illustrate how the machine shown may be organized as a double machine, that is, as one which is operated from both sides,-front and back,with a plural set of swifts, thread carriers, spindles and spindle frames, on each side,and by the utilization of a single mechanism for operating duplicate carrier bars and feed shafts.

Throughout the description we at times use the expression quill as meaning the completely wound ultimate product which is otherwise technically known as a cop and use the expression cop-tube to refer to the conical tubular body which is slipped upon the spindle and upon which the thread is wound to form the product-being the quill or cop of commerce.

The framework and prime-moving mecham'sm.

consideredtogether as aframework,.all of bar and the feed shaft and for also occasioning the intermittent rotation of said feed shaft, are merely mechanisms convenient for the purpose, and other devices for effectin the same movements can obviously be su stituted for them;

It having already been explained how the spindle frames 9 which carry the spindles 11- and the cop-tubes 18 placed on said spindles, are rotated by the rotation of the friction Wheels 20 on the front driven shaft 21, it will be understood that when the cop tubes ,have been placed upon the sgindles and the spindle frames dropped a out their pivots 8 until the friction pinions 17 are caused to rotate by the rotation of the grooved friction wheels 20 on the front driven shaft 21, it is the rotation of this shaft 21 which occasions the starting of the rotation of the cop-tubes and their readiness to be wound with the threads which are to form the cops or ultimate products.

Assuming that instead of cop-tubes, spools were mounted upon the spindles and caused to be rotated by the friction wheels, it will be apparent that withthe devices already described, namely, the drivin shaft 27 and the bevel gears 25 and 26, Fig. 18,

' the driven

shafts

21 and 24 and the swifts 6,

the well-known found.

To this typical winding machine our invention first applies the reciprocating carrier'bar 38 and the reciprocating, intermittently rotating feed shaft through the operating mechanisms already described and the spindle frames,and then applies thedevices which in this specification are termed the thread-carriers an embodiment of which is the following winding machine will be The thread carrier and its adjwncts.

Referring now more particularly to Figs. 7, 8, 9, 14, 15, 16 and 17, the thread guide carrier which herein we call the thread carrier, is a device mounted upon and carried ythe carrier bar 38, and adapted to be reciprocated with relation to each cop-tubecarrying spindle and spindle frame longitudinally end for end of the machine to a right and left-hand traverse about equivalent to the length of the finished cop upon thespindle. y

' One of these thread carriers is applied to operate with each one of the spindle frames so as to carry and otherwise handle the thread from the skein to the cop-tube in a way about to be explained.

Each thread carrier is also operated upon by the intermittently rotating and reciprocating feed shaft 60, the essential function of which in connection with the thread carrier is to cause the latter to'stop in its traverse in the eventof the breaking of the As all of the desired plurality of thread carriers are of the same construction, a description of one of them will suffice.

Each of the operative elements of a carrier is mounted upon, and assembled with relation to, a carrier body 79 which may be cast as an entirety or made up as shown in the drawings of assembled and connected parts,-it being an essential, however, of the construction that the carrier body should be formed with a slot 80, which is transverse of the length of the carrier body as a whole, but parallel with the carrier bar 38 upon which the body is mounted and accurately fitted and held for frictional adjustment or slippage by means of a springcontrolled pin 81 shown in Figs. 9 and 10,by which adjustment is meant a capacity of controlled slippage or sliding end for end of and upon the carrier bar 38. V

The component operative elements of the thread carrier are (a) a vertically movable split nut,(b) a nut-control, or balanced counterweighted control of the split nut,- (c) a trigger mechanism for locking and unlocking the nut control,(d) a balanced oountemveighted thread-finger-carrying device, operative automatically when the thread which passes through the thread carrier from the skein to the cop tube, breaks, which locks and releases the trigger mechanism which controls the nut-control,(e) a series of fixed thread fingers which operate in connection with the movable thread fingers on the balanced counterweighted thread 1 finger-carrying device,(f) a. thread tension, (g) thread guides at-the front and at the rear of the thread carrier as a whole, and (h) an automatic thread cutting device for cutting the thread either first when it 10 breaks in being wrapped, or second when it has been completely wound upon the coptube to form the finished cop.

We will explain these elements of a thread carrier, sem'atz'm:

The split nut.

The split-nut 61 is internally threaded to correspond in pitch and number of its threads to the threads of the

feed shaft

60, 115 so that when the nut is engaged with the feed shaft and the shaft in rotation,- the thread carrier will be caused both to reciprocate lengthwise of the machine to the extent of the reciprocation of the carrier bar 2 being itself mounted upon a t-ongued slide 82 fitted in a grooved slide-way 83 vertically formed in the rear of the carrier body 79 behind the slot'80.

The split-nut control.

84 is the balanced counterweighted control of the nut, or nut-control, so called, which is composite of a lever 85 extending rearwardly of the counterweight proper to which the number 84 is applied, from pivots 86 formed near the bottom of the carrier body 79.

A spring 87 connects the rear end of the

balanced lever

85, 84, with the nut, and, when the balanced lever has been released from its manually placed normal position of Figs. 7 and 9, serves in connection with the weighted balanced end 84 to lift the lever, slide and nut from the normal position shown in Fig. 6 to the abnormal or elevated position shown in Fig. 14, and in so doing of course occasions the lifting of the nut from the screwshaft by the contact of the lever-with the lower end of the slide 82, as shown in all the views. I

When the nuthas been lifted, it occupies the position shown particularly in Fig. 14 where a bar 88 extending rearwardly from the slide 82 and to which the nut may be conveniently pivoted encounters a rearwardly extending plate 89 which is a part of the carrier body.- This'of course is a stop construction of convenience, and any stop to limit the upward movement of the slide and nut may be substituted for 'it.

The trigger mechanism for the nut-control.

ally from the counterbalance lever 84, 85.-

The lower front portion of the trigger 90 is formed with a 'rearwardly extending curved surface or curve 94 against which abuts and travels a pin 95 on a bell crank lever 96, pivoted at 97, to a depending portion 98 of the carrier body 79.

The balanced counterweighted thread finger device.

The bell crank lever 96 as to the front edge of its upper arm bears against a lever pin 99 extending laterally from what we have termed the balanced counterweighted threaded finger-carrying device, 100,which device itself is a flat plate paralleling the plane of the fore and aft length of the carrality, as shown, of three, horizontally disposed fingers 102, which are so placed that in the lift and drop of the plate about its pivot 101, they occupy a staggered relationship, as shown in Figs. 15 and 16, to a plurality'of fixed pins 103 on a forwardly extending horizontal plate 104 of said carrier body, as shown in Figs. 6,.7 and 14.

The thread tension and thread guides.

To the front and to the rear of the plate 104 are respectively connected an upwardly turned guide finger 105 and a downwardly turned guide finger 106, which, as shown 11 Fig. 7, cooperate in the. threading or passage of the thread 109 along the carrier,the thread being first passed from the cop tube 18 to which it is carried from the skein 7 and attached,the-nce through the thread guide 110,thence through the open cutter later on described,thence under the I'GELF' guide finger 106,thence over the fixed finger pins 103 and under the fingers 102 of the plate 100,thence over the front guide finger 105,thenc.e through a tension device 108 of any usual character,and thence through a front thread guide 107 and onward to the skein 7.

In the application to and the carrying along through the thread carrier of the thread between the skein 7 and the cop-tube 18, the carrying plate 100 has been raised,

as shown in Fig. 15, so that the thread has been passed over the fixed fingers 103 on .the plate 104, beneath the movable fingers 102 on the uplifted swinging plate. 100,

which is then droppeduntil its fingers -102 rest upon the thread and bend it as shown in Fig. 16. I

The tensionand strength of the thread when passed. completely along the thread carrier from the skein to the cop-tube is alone sufiicient to hold the finger-carrying plate 100 in its upper position, as shown in Figs. 6 and 7, and in such normal position of the operation the plate 100, the trigger 90, the bell-crank lever'96, and the

counterweighted lever

84, 85, are all in the locked positions represented in Figs. 6, 7 and 9,-

with the split nut upon the feed shaft, and in such position they will remain until the thread breaks and permits the plate 100 to drop and through the bell-crank and the.

the active elements of the machine are supported and applied.

Although the elements are in duplicate, we will describe only one set of them as applied to the front side of the machine, describing however an operating means by which such front set of elements and also a duplicate rear set may be simultaneously operated when the machine is a double machine operated by two operatives, one standing upon one side and the other upon the other.

3 are hangers extending obliquely outward and downward from the frame beam 1 and terminating in double socket bearings 1 into which the hubs 5 of the swifts 6 which carry the skeins 7 are adapted to be dropped and permitted to revolve. There are a set of swifts upon each side of the machine.

Mounted upon the frame beam through the carrying cop-plates 1*, by being pivotally connected thereto by the pivots 8, are a plurality of spindle frames formed each of a pair of pa 'allel side bars 9, 9* which are connected by a bar 19, which serves as a weight to hold the frames down.

To the outer or front ends of these spindle frames are adaptedto be removably applied the spindles 11, Figs. 11 and 13, the trunnion 12 on one end of each of which is adapted to be entered within a socket 13, Fig. 6, and the trunnion 11 on the other end of each of which is adapted to be entered and snapped within another socket 15, Fig. 12. and held therein by a spring 16.

Upon the inner end of each spindle is a preferably'removable friction pinion 17, best composed of fiber, adapted when the coptube 18 has been slipped upon the spindle 11 and the spindle frame has been dropped to its operative position, to make contact with a groove 19' in a friction pulley 20 mounted upon the front driven shaft 21 which extends longitudinally across the front of the machine and is mounted in bearings 22 supported conveniently by transversely extending standard arms 23, Fig. 3, or by some other preferred partT f the framework.

In the assembled machine when arranged to operate as a double machine, the front driven shaft 21 which, as explained, parallels the front face of the frame beam 1. has a counterpart rear driven shaft 21, shown, broken off, in Fig. 3, as mounted in the bearing 22*, and both of these shafts extend in parallelism with each other and with the frame beam for the length of the machlne, and terminate at the left-hand end as shown in Fig. 18 and are respectively connected through two bevel gears and 26 w1th a driving shaft 27 driven by a belt 28 and pulleys 29 from any source of power.

Obviously, in the rotation of the driving shaft through the bevel geais, the front driven shaft and the rear driven shaft. will rotate oppositely in the direction of the arrows shown in Fig. 18.

The thread carrier carrying-bar and its actuate-11g mechanism and adjuncts.

The actuation of the motive mechanism of the thread carriers through the carrier bars and feed shafts is effected and controlled in the following manner 2-21 designates a front driven shaft which at its righthand end is provided with a toothed pinion 30, meshing with a toothed spur wheel 31, mounted upon a fixed shaft 32 which extends horizontally and outwardly from the righthand standard 2 of the frame, conveniently by means of a bracket 33, as shown in Fi 1.

aonnected with the spur wheel 31, conveniently by being hubbed to it at 31, on the shaft 32, is an eccentric 35, Figs. 2 and 3, and also a side face cam 36, itself preferably hubbed at 37 to the eccentric,s0 that all three,spur wheel, eccentric and cam. are rotatable together on the shaft 32.

The function of the eccentric is to occasion the intermittent rotary movement of the screw or feed shaft 60, and the function of the cam to occasion the longitudinal reciprocation of both the carrierbar 38 and the screw shaft, as hereinafter explained.

Before describing the thread carriers which are mounted upon the carrier bar so as to be susceptible both of intermittent reciprocation with and of frictional movement endwise upon it, it should be explained that the carrier bar 38 itself is a horizontally disposed, verticallyset, metal bar pa alleling ,the frame beam of the machine. and supported for reciprocatory movement longitudinally of the machine in bearings 10 erected upon hearing supports 11 attached to the frame beam, its movement being made easy by providing for it to rest and move upon, within the bearings 10, anti-friction rolls 12, as seen in Fig. 1.

A given reciprocation of the carrier bar 38 will, as is obvious. occasion a given reciprocation of each of the thread carriers attached to said carrier bar. The desired reciprocation of the carrier bar may be effected by many means. but we find it convenient to effect it by connecting the bar by a link 13 with a compound system of rocker arms of the following construction 11 is a rocker arm fulcrumed midway of its length at 15 to a

bracket

16, 16*. attached to the right-hand standard 2 of the frame- \\ork.thc link 13 being pivoted at 17 to the right-hand outer end of the carrierbar 38, and by a nut and long bolt adjustment 18, Figs. 1 and 3, working through a slot 1!). connected to the upper end of said rocker arm 11 above its fulcrum 15.

The lower end of this rocker arm 11 is slottedatfit) and 1 another nut and bolt adjustment 51 is connected with a second rocker arm 52 pivoted at its lower end at 53 to a stud 54 on the standard 2, and extending upwardly to abreast the cam 36 against the outer side face of which it bears by a roller 55, Figs. 1 and 3, so that in the rotationof the cam, said rocker arm 44 is deflected about its pivot 53 and through its connection 51 with the rocker arm 44 will be deflected outwardly and inwardly so as to occasion the right and left, or out and in, movement of the link 43 and the consequent reciprocation of the carrier bar 38 to an extent determined by the configuration of the acting side face of the cam and the proportioning of the

rocker arms

44 and 52 relatively to each other throu h the fulcrum 45 and the pivot 53 and their nut and bolt adjustment or connection 51.

While, of course, the outer side face of the cam 36 by its contact with the roller 55 will occasion the right-hand or outward throw of the rocker arm 52, the roller 55 on'said rocker arm must always be retained against the cam face. This retention We conveniently accomplish by means of a transversely extending pressure-retaining bar 56 which extends between the outer face of the rocker arm 52 and the outer face of a counterpart rocker arm 57, which is provided with a roller 58, which also bears against the diametrically opposite working, side face of the cam 36. J p

The retaining bar 56 is held in contact withv both the

rocker arms

52 and 57 by being itself connected with a spring 59 fast to the framework.

Although we have fully illustrated only the rocker arm 57 which is the counterpart of the rocker arm 52, it is of course to be understood that in the dual organization of the machine, that is, when the machine is operated from both sides, there is provided another rocker arm, not shown, except as 44 in plan in Fig. 3, which is the counterpart of the rocker arm 44, and that the connection ofthese last-mentioned two

rocker arms

57 and 44 is similar, by a link, not shown, connecting them with a second carrier bar also not shown, to a link connection 43 already described with reference to the carrier bar 38.

The thread carrier feed .shaft and adjuncts;-

carriers occasioned by the reclprocation ofthe carrier bar, as also hereinafter explained. The feed shaft isa continuous, screw shaft the pitch and number of the threads of which are so calculated that the shaft is in eflect a worm shaft which operates to occasion the right-hand advance of each thread carrier by being engaged with a correspondingly threaded mutilated or split nut 61 connected with the thread carrier.

This feed shaft normally reciprocates with the carrier bar by which it is carried and to which it is connected conveniently by the shaft boxings 62, Figs. 3, 4 and 5, which are semi-cylindric bearings within which the feed shaft is free to rotate and which conveniently possess the form shown in Fig. 4 and are shaped to embodythe slots 63 so that the boxings can be slipped from beneath upwardly from the carrier bar and fastened to it by the bolts 64.

As shown in Fig. 5, the upwardly open socket 65 of the boxing 62 is fitted with a bushing 66 passing through it and having a smooth bore within which the threads of the feed shaft turn; Any desired number p of these boxings may be employed. The feed shaft 60 is adapted to have imparted to it normally both a movement of constant longitudinal reciprocation with the carrier bar 38, because its threads are normally in engagement with the threads of the split nuts 61 within the thread carriers on said bar,and also a movement of intermittent rotation by connection with a ratchet wheel 67, which is keyed upon a connecting shaft 68, Fig. 19. This connecting shaft is a continuous alined connection or extension of the feed shaft 60, bein connected to the latter by a coupling 69, ig; 3, and it is conveniently housed for rotation in bearings 70 and 71, Fig. 19, formed in a supporting loop 72 conveniently supported from the.

standard 2 of the framework and serving to house the ratchet wheel 67, which as is shown in Fig. 19, is connected by a key" carrier 75 .p1voted at 76 to the frame and connected by aneccentric link 77 and eccentric stra 78 with the eccentric 35, as best-shown 1n Fig. 2.

In-the throw 0 the eccentric 35 which the rotation of the toothed spur wheel 31 oocasions, the swinging pawl carrier 75 will obviously be swung about its pivot, and swinging the pawl 74 will cause a predetermined'rotation of the ratchet wheel 67 and a consequent predetermined rotation of the connectin shaft '68, as already referred to. All of t eforegoing instrumentalities for Occasioning the reciprocation of the carrier trigger and the nut lever all being released from their set position, will occasion the lifting of the nut.

The thread cutting mechanism.

The thread cutting] mechanism which when the thread has been passed through the guides, tension device and fingers, as already described, is normally open for the thread to pass through it. as shown in Figs. 6, 7 and 8,is composed of a fixed cutting blade 111 rightangular of the carrier body and extending preferably across the rear face of the plate 89, and of a pivoted cutting blade 112, the pivot of which is 113, erected in a vertically disposed cuttercarrying plate 114 erected from the carrier body 79, and which is adapted to be locked in its forward or non-cutting position, as shown in Figs. 7 and 8, by a pivoted latch 115 the pivot of which is 116 and which is formed with an upper notch 117 and a lower notch 118 into one or the other of which is adapted to be entered and engaged a notched pin 119 extending laterally from said pivoted cutting blade,as shown in the uncutting position in Figs. 6, 7 and 8 and in the cutting position in Figs. 14 and 17.

The normal or open position of the pivoted cutting blade being that represented in Fig. 8, it will be observed that beyond its pivot 116, the latch is formed with an unlatching arm 120 which in the travel of the thread carrier from the left to the right of the machine is adapted to encounter a stop 121 on the carrier bar 38 and be by it deflected so as to deflect the latch and release the notched pin 119 from the upper notch 117 by throwing the latch into the position represented in Fig. 17 in which position the pivoted cutting blade will then be thrown down by the action of a blade controlling spring 122, as shown in Figs. 7, 8 and 14.

The return of the cutting blade to its lifted position as in Fig. 8, from its dropped position as in Fig. 17, is effected by the operative who depresses the unlatching arm 120 inwardly from the position shown in Fig. 8 to the position shown in Fig. 17 with the result of lifting the cutting blade 112 against the resistance of its spring 122 until the upper notch 117 engages the notched pin 119, as shown in Fig. 17.

\Vhen at the completion of the traverse of a carrier with reference to the spindle and cop-tube with which it operates, it becomes necessary to sever the thread, the cop having been completely formed, the unlatching arm 120 encounters the stop 121 and occasions the cutting of the thread. 2

In the event, which is unlikely, that the finger carrying plate 100 should not have dropped at the completion of the operation of the winding of the cop, we assure its dropping by providing a cam stop 123 fixed on the carrier bar 38, which stop is adapted to be encountered by the bell-crank lever 96 andautomatically through the trigger 90 to release both the

nut lever

84, 85, and the finger-carrying plate 100.

T he operation of the machine.

Having now described the operative elements of our machine as a whole, and in doing so described more or less fully the operations of each element,the general operation of the machine is the following' Assuming the required number of coptubes to have been put in position upon the spindles, and assuming the threads from the corresponding swifts and skeins to have been drawn through the thread carriers and connected with the cop-tubes, the prime moving or motive mechanism of the machine shown in Fig. 18 is then put into operation with the result that it will, first, occasion the rotation of both of the driven

shafts

21 and 24, and through the pinion 30 and spur wheel 31, the throw of the eccentric 35 and rotation of the cam 36, so as also to occasion the throw of the ratchet wheel 67 and through the pawl 74 and pawl carrier 75, the intermittent rotation of the feed shaft 60,and also through the rotation of the cam 36 occasion the oscillation of the compound rockers,and with the further result,-second, that the feed shaft 60 will be caused both to intermittently rotate and to reciprocate, and the carrier bar 38 to reciprocate constantly,the operations of reciprocation and rotation referred to being predetermined by calculated dimensions and movements of the operative devices referred to.

Assuming, further, that the operation of the driven shafts through the friction wheels 20 will occasion through the friction pinions 17 the desired rotation of the spindles 11 in the spindle frames, it is obvious that the connection of the threads with the cop-tubes upon the spindles, will, in the rotation of the spindles, occasion the drawing of the threads through the thread carriers, the assembled operative mechanisms of which are initially in the position particularly represented in Fig. 7 with the thread 109 drawn through the thread guide 107, the tension device 108, the guide finger 105, beneath the fingers 102 of the finger carrying plate 100, above the fixed fingers 103 of the frame plate 104, beneath the guide finger 106, between the then separated cutting

blades

111 and 112 of the thread cutting mechanism, and, finally, through the rear thread guide 110 on to the cop-tube.

So long, then, as no break occurs in any thread from any skein, the continuing cal culated end for end reciprocation of the thread carriers will, under the proper timing of the rotation of the spindles and the calculated movement relative thereto of the thread carriers, cause in each right-hand reciprocation of the thread carriers a threadwrapping of such length of the cop-tubes as equals the then calculated advance reciprocation of the thread carriers, while after the return reciprocation of said thread carriers,their intermittent advance occasioned by the rotation of the feed shaft taking place simultaneously with the return movement of the thread carrier,there will follow a succeeding right hand advance of said thread carriers which will start and occasion the winding of the thread upon a new surface-layer, so tospeak, which will progressively overlie the underlying wound surface.

This operation is really one compound operation due rimarily to the conjoint reclprocation of t e carrier bar 38 and the feed shaft 60, but secondarily due to the intermittent rotation of the feed shaft which without regard to its reciprocation occasions a continuing although slight forward advance of thethread carriers through the action of the threads of the feed shaft on the split nuts, the same being a continuing advance throughout the length of the cop-tube, with the result that the winding is performed in a uniform way but layer upon layer, so to speak, the beginning of each layer at the basal end of the cop-tube being a progressiveadvance upon each succeeding layer until the cylindric central portion of the cop-tube has been covered and the cop as to such central portion made uniformly cylindric, while afterward the continuing forward laying is a progressively diminishing laying, so to speak, toform the diametrically narrower outer end portion of the ultimate cop.

The typlcal diagrammatic view of Fig. 20 while of course entirely. out .of proportion in both the numbers and the diametersof the threads as laid and wound, will give an idea of the operation as practically conducted at great speeds and with threads of the smallest commercial diameters. 7

Thus, as explained, if no thread breaks and the machine is in continuous normal operation, each of the cop-tubes will be wound in such a way as to have formed upon it a double conical cop or quill of a completed commercial character. I

'If, upon the contrary, during the progress of the operation one of the threads from any one of the skeins should breakflas typically indicated in Fig. 14, the instant effect of the break will be that the finger-carrying plate .100 which the normal tensile strength of the thread itself has been suflicient to maintain in the elevated position represented in Figs. 6 and 7 will gra'vitatively drop into feed shaft ;mechanism for

occasionin

84, 85, with the result of. occasioning the lifting of the split nut so as to free the thread carrier from the feedshaft and stop such longitudinal movement of said feed carrier as is due to the operation of the shaft upon the nut.

It will now be apparent that the abovedescribed machine is adapted to effectuate the objects which we have enumerated as de sirable, and that, as already mentioned, modifications in detail of the several elements may obviously be resorted to without departing from the spirit or scope of our invention or sacrificing any of its advantages.
