SPECIFICATION forming part of Letters Patent No. 389,013, dated September 4, 1888.

Application filed May G, i887. Serial No. 237.311. (No model.)

To MZ whom, may concern:

Bc it known that I, VERNON ROYLE, of Paterson, in the county of Passaic and State of New Jersey, have invented a new and use fnl Improvement in Machines for finding Shuttlc-Quills, Sac., of which the following is a specification.

My invention relates more particularly t0 machines for winding shuttle-quills with silk or other material; but certain features thereof may bc employed in machines for winding other spools or bobbins.

The machine which I have illustrated in the accompanying drawings is somewhat similar in its general character to the machine which forms the subject ol' my application for Letters Patent, Serial No. 206,194, tiled June 25, 1886, and my present invention may be said, in a general way, to consist iu improvements on that machine.

ln machines of this character there are usually arranged on opposite sides ofthe main frame of the machine two series or rows of spindles, cach spindle being combined with a ther, and one of said parts being rotated relatively to the other. In the example of theinvention illustrated in the accompanying drawings the tlicr is rotated relatively to t-he spindle andisd riven through a clutch from a wheel or pulley. Tilhcn the clutch is constructed with projections or members which positively yielding of one member relatively to the other, the sudden starting of the iiier at full speed sometimes breaks the thread, especially in winding liuc silk; and one feature of mypresent invention consists in novel combinations of parts which include a combined frictionclutch and positive clutch for driving the rotary part, or, in other words, a clutch which first engages by frictiomand when fully shifted or thrown on engages by positively interlocking portions. This clutch may be formed by a pair of laterally-yielding springsupported the flier-and a conical spreader' constituting the other part or member of the clutch. The conical spreader is preferably upon a whirl, and at the base of the conical or taper surface is a pin or projection which when the spreader is advanced sufficiently far between thelaterally-yielding jaws engages with one of said jaws and so forms a positive interlocking of the two parts of the clutch. By this construction the dier is started gradually, and in first starting an opportunity for slip between the two members of the clutch is afforded, and even delicate thread will not be broken. I preferably' construct the conical spreader with a reversed taper or conical surface at the base of the one which is active in engaging the clutch, so that the spreader will not produce a continued upward pressure upon the other member of the clutch and the hub of the dier. I also combine with the laterally-yielding member ofthe clutch a brake for arresting or retarding the rotation of the hier when the clutch is thrown off, and the brake may consist of a pin or pins projecting laterally inward from the two jaws, which form one member of the clutch,through openingsiu the flierhub, and which bear at the inner end upon a xed tube which surrounds the spindle and on which the flier-hub rotates.

The invention also consists in other novel combinations of parts hereinafter described, and pointed out in the claims, and which include a flier comprising an arm which is split or slotted lengthwise from ono end in ward, and a guiding eye hanged at opposite ends and held between the fingers formed by the slot in the flier-arms, which enter a circumferential groove between the flanges. This eye may be placed in position by laterally displacing one of the fingers formed by slotting the dier-arm away from the plane of the other ringer, as will he hereinafter described.

The novel combinations of parts also include hinged clutclrlevers which are upon the up per end of the spindle, and which engage a groove in the quill for holding it upon the spindle,and a bow-spring ofsemicircular form, the ends of which are engaged with or enter indentations in the said clutch -levers and cause them to spring into engagement with the groove in the base of the quill.

The novel combinations of parts also include novel features in a stop-motion, whereby the mechanism for throwing off or discngaging the clutch in order to stop the operation is antornatically rendered operative on the breaking of a thread. These novel combinations of parts also include, in connection with a cam and a canrlever operated thereby, and suita- TOO ble connections through which a traverse motion in one direction is imparted to the spindles in a row or series, springs applied one to each spindle for producing a traverse motion in the reverse direction, and which serve to take up all lost motion in the connections through which the spindle is traversed.

The novel combi nations of parts alsoinclude, in connection with spindles and fliers and means for driving one relatively to the other, tension-brackets having short guides of novel construction projecting from opposite sides thereof, as distinguished from guides consisting of long rods extending lengthwise of the machine. 'The short guides on opposite sides of the tension-brackets are much more advantageous than the long guide-rods, because in preparing the machine for operation, and in` replacing the thread in proper position after breakage, the thread may be passed endwise over the guides instead of being threaded through or over the guides, as is necessary when they consist oflong rods. The threadguides consist of porcelain, glass, or analogous smooth material which will not be readily worn, and the novel combinations of parts above freferred to also include novel features in the way of securing these guides or guidingsleeves to the tensionbrackets.

rIhe above novel combinations also include, in connection with a spindle to receive aspool or bobbin and a brake for acting on the spool or bobbin, said brake preferably bearing di.- rectly upon the material wound on the spool or bobbin, a support to which the brake is pivoted, and which is adjustable around the spindle to vary the action produced by gravity of the brake upon the spool `or bobbin. This support may bejournaled directly upon the spindle and provided with a set-screw, whereby it maybe secured in place after being adj usted around the spindle.

'Ihe novel combinations of parts also include, in connection with spindles and fliers on op posite sides of a machine, two cams having a common axis and having the projections or points of greatest projection of one arranged opposite the depressions or points of greatest depression in the other, and mechanism, substantially as hereinafter described, whereby the two spindles are traversed in opposite directions simultaneously. Where the spindles are upright, as is usual, the weight of parts assists the downward traverse and increases the resistance to upward traverse of the spindle, and

where one series is moved upward and the other series downward simultaneously the resistance to the traverse is rendered more unin form than itis where both series are moved simultaneously upward or downward. These two cams may be formed by circular cam-surfaces on opposite sides of the cam-wheel, and in machines of this class I prefer to form the cams of a series of long and short inclines arranged alternately, so as to produce a slow traverse of the thread on the quill in one direction and a quicker traverse of the thread in the other direction, the advantages of suc'h difference in traverse being well understood in the art. To render stil-l more uniform the resistance offered to the traversing movement of the spindle, I prefer to construct the camwheel so that the inclines upon one side or face, whichconstitutes one cam, overlap the inclines upon the opposite side or face, constituting the other cam, so that the inclines of one cam always commence their action before the termination ofthe action of the inclines of the other cam, and there will then be no time in the operation ofthe machine when there will be no resistance to the m-ovement, as would be the case if both cams acted exactly simultaneously.

In order to drive the cam-wheel, a worm or spur gear has been employed, and to secure simplicity and economy in construction and compactness of the machine I employ a combined spur or worin wheel, which consists of a circular series of worm or spur teeth and a zigzag web portion within such circular series of teeth, and having on opposite sides long and short inclines arranged alternately. The levers on which the cams operate are tangential to the circle in which the inclines are arranged, and in some cases the bearers on which the cams act consist of polygonal blocks mounted on levers.

It is obvious that points in the circle near the outer circumference of the cam move faster than points in the circle near the inner circumference of the cam, and where a solid block is employed it has not, during the entire operation of the cam, a bearing throughout its entire face upon the inclines. To enable this result to be secured, and therefore to reduce wear and prevent lost motion in the parts of the machine, I construct the bearingblocks for the levers, and on which the cams act, of a number of thin and freely turning plates placed side by side, and which readily adapt y themselves to the facesof the inclines, and I also provide a novel and simple construction whereby a forked link, through which the canr actuated lever transmits motion, may be connected with the lever.

All the tigures except Fig. 1 are upon a larger scale than said ligure, and similar letters oi' reference designate corresponding parts in all the iigures.

The main frame of the4 machine comprises cud standards, A, and longitudinal stretchers B, extending between them and supporting It will be understood that the series or row of spindles C is to be arranged ou each side of the ma chine, as is represented in my aforesaid application, Serial No. 206,19-t, and I have thought it unnecessary to here show aside elevation of the machine. Ten, twenty, or any other number of spindles may be arranged on each side of the machine.

I will iirst describe the construction of a spindle and ilier, together with its appurte nances,it being understood that the description applies equally to each spindleiu the machine.

To the longitudinal stretcher or rail B is secured aspindlebracket, B', and iu this bracket is secured in iixed position a tube, C', as in my aforesaid application. This tube may be secured in the bracket by a set-screw, c, or otherwise, and is ot'such size as to receive the spindle C freely and yet snugly through it. The spindle is tubular, and through it extends a iiXed rod, C, which is here shown assecured in fixed position at c in a bracket, C3, secured at c2 to the lower end oi the fixed tube tl'. The rod C'l extends upward through and above the spindle C, and supports at its upper end a hollow abutment, G, which is con centric with the spindle, and the function of which will be hereinafter described. The quill s is mounted on the top of the spindle C, and, as here represented, has at its base a circumferential groove, s', with which engage the ends of clntchlevers s, which are fulerumed at By means oi a bowsspring, 3*, of semicircular form with a coil, and which has its ends engaged with the levers 8"', the upper ends of the levers are automatically held in engagement with the groove s' in the base of the quill.

D designates a iier-hub, which,as best shown in Fig. 4, is journaled on the fixed tube C', and has an upwardlyprojecting arm, D', provided with a thread eye or guide, d. In machines of this character the spindle and iiier are rotated one relatively to the other, and in this example of the invention the spindle is nou-rotary and the flier is rotated rapidly upon the iixed tube C by power transmitted from a whirl or pulley, Dt. As here reprcsented,the dier-arm D is slotted or divided lengthwise from one end inward, as shown at d', thereby forming flexible lingers for grasping between them the guiding eye d, which at opposite ends or sides is danged, as shown in Fig. One of the fingers formed by the slot d' may be bent in the direction of its thickness out of the plane of the other finger, so as to separate them sui'- ticiently to insert the eye d between them, and the fingers, by their resilience, return into the same plane and thus hold the eye securely against displacement.

As shown in l, the whirls l)l ol' two spindles on opposite sides of the machine may be driven by a single band, D, vfrom a pulley or drum, D", upon the main shaft Di", and motion is transmitted from each whirl D to the flier-hub D by a clutch, which may be thrown off or on at will, in order to stop or start each spindle independently of the others, asmay be necessary, by the running out of the spool E, from which the thread o is taken by the breaking ot" the thread or by the quill s upon the spindle becoming full. Vheu the clutch is of such character that its two members engage independently by a positive interlocking of projections, one niember of the clutch is moved lengthwise and the iiier is instantly started at full speed, thereby not only bringing an increased resistance suddenly upon the drivingband D3, but producing a sudden draft upon the thread, which, it' it is thin, is liable to be broken. To obviate this difficulty, I employ a combined friction -clutch and positive clutch, the two members of which are construct-ed to engage first by friction on the first movement oi' the sliding member ofthe clutch, and subsequently, on the completion of such movement, by the positive interlocking ot' parts, and in this way I secure a gradual starting oi' the dier and an opportunity for the slipping of one part ofthe clutch upon the other part or member, which prevents any sudden jerk upon the thread and avoids breakage thereof.

As here represented, one. member of the clutch consists ot forked or bifurcatcd jaws di, which are pivoted at di on opposite sides of the tliervhnb andare connected by aspring, (1*. The other member oi' the clutch, which is formed upon the whirl Di, comprises a cen- IOO IIO

tral spreader having aconical or taper surface, d5, and at the base of such cone or taper one or more pins or projections, de. As here represented, the whirl D2 has an annular groove, di, which receives a fork, d8, on the upper end of `the pin or stem d, arranged to slide in a suitable socket in the bracket B and having a spring, dm, applied below the bracket and above a collar, d, on its lower end.

In the position of parts shown in Fig. 3 the clutch is thrown off or rendered inoperative, and the iiier D is supposed to be stationary. Then the whirl D2 is raised by the action of the fork d8, the conical surface d5 of the spreader enters between the laterally yielding and spring-supported jaws d2 and by its frictional engagement with the points of said jaws tends to rotate the flier D. Such rotation, however, is not positively effected, and there is ample opportunity for slip between the conical surface di and the jaws cl'l until the whirl has been raised, so that the pin or projection d is in the same horizontal plane with the jaws d2, whereupon such pin engages positively with the side of one of the jaws, and motion is thereafter transmitted to the flier positivelyT and without any slipping.

It will be observed that the action of the conical or tapered surface d5 on the yielding jaws d2 not only spreads them, but has a tendency to produce au upward pressure on them and on the hier-hub D, with which they are connected. In order to relieve such upward pressure and avoid unnecessary wear of the flier-hub D and thc fixed tube C', on which it isjournaled after the parts of the clutch are in positive engagement, I have shown the spreader on the whirl DAZ as having below the conical or tapered surface d a reversely-tapered or dow nwardly-tapering surface, and as soon as the pin or projection d6 is lifted into engagement with thejaws d said jaws are in contact with the downward or reverse taper d, and the Iller-hub is relieved of upward pressure.

In order to lay the thread 0 conically upon the quill s in the usual manner of building up cops, the spindle C has imparted to it a longitudinal traverse. As each layer ofthread is placed upon the quill, beginning at the base and progressing upward, it will be linderstood that the height of the quill is slightly increased, and,inasmuch as the traverse movement is through a definite range, the quill will at the termination of each upward traverse be brought in contact with the abutment C4, which is supported concentrically with the quill.

As described in my aforesaid application, I impart a traverse motion to the spindle by a frictionclutch, and as the winding of the quill progresses, and at the termination of each upward traverse of the spindle, the quill strikes the abutment C", and the spindle is pushed slightly downward.

As here represented, the mechanism for producing the traverse movement of the spindle in one direction consists of a rock-shaft, F, and cams or toes F-one for each spindlemounted on the rock-shaft, and also applied to the rock-shaft is an arm, F2, which by a link, F3, is connected with the lever Ft, carrying a block or shoe,f, on which acts a eamwheel, F5, as shown in Fig. 1 The lever F4 is, as here shown, fulcrunied at its lower end, f', and the details of construction of these parts will be hereinafter referred to.

For traversing each spindle C the arm or toe F pertaining thereto engages by a fork or notch,f2, a clutch body, H, which is fitted to slide upon the fixed tube C', and has at opposite sides levers h, drawn toward each other by a spring, h', and each carrying a shoe, h, which extends through a slot, h, in the fixed tube C' into contact with the spindle C within said tube. construction as is shown in my aforesaid application` and, although by the action of the spring h the shoes h2 are held with sufficient pressure upon the spindle C to prevent slip in performing the principal portion of the traverse movement, they will permit the spindle C to be slid very slightly' downward 'through the clutch-body when the quill comes in contact with the fixed abutment Ct. The `mechanism shown transmits upward traverse, or traverse in one direction to the spindle C, and for assisting and insuring traverse in a reverse direction I have represented a spring, h, as applied to each spindle or clutch-body H, this spring being here represented as secured at one end to a projection from the bracket G3 and at its other end to a projection from the clutch-body. The springs h* applied for the several spindles have their aggregate strength sufficient to insure the downward traverse of all the spindles on that side of the machine and to hold the bearing block or shoefof the cam-actuated lever F* against the cam-wheel F5, thereby taking up all lost motion due to wear in the connections.

As here represented, the cam-wheel F5 actuates two levers, F, which each operate all the spindles upon the side of the machine, and the opposite faces of the cam', which are at right angles to the axis thereof, may be considered as constituting two cams, which have a cour,

mon axis. For rotating the cam I employ a spur or worm wheel or circle of teeth,f3, with which engages a worxn,f, upon the main shaft D5, and I have here represented the camwheel F5 as formed integral with the circle of wormteeth or spur-teeth. In other words, Iconstruct and combine the worm or spur wheel and cam-wheel, which comprise the "circlef3 of worm or spur teeth, and the cam portion F5, which is formed by the web of the wheel within the circle of teeth, as is best shown in Figs. 16 and 17.

As represented, eachsurface of the camwheel F5, whichmay be considered as constituting a cam,is made up of :inclinesff which maybe termed long and short as compared with each other, and which are arranged This rlutch may be of the `same LII alternately in the circumference. N ot only may the inclines be considered as long and short, but the short inclines are of different lengths and the longinciines are also of different lengths, and the result of this construction is to produce a comparatively quick traverse in one direction and a comparatively slow traverse in the other direction, and to vary minutely the traverse in each direction, there by imitating as closely as may be the results produced in winding quiils when the traverse is produced by hand.

It will be observed that in the two earns which are formed by opposite faces of the zigzag web or wheel F5 the points of greatest projection in one cam or side are approximately opposite the points of greatest depression in the other cam or side, and hence the series of spindles at one side of the machine will be traversed upward si multancously with the downward traverse of the spindles on the opposite side of the machine, and the resistance to the operation of the machine will be more uniform, because more power is required to make the upward traverse than the downward traverse. 1n the former case the weight of the spindles and their quills is an additional resist-ance, while in the latter case the weight facilitates the downward traverse.

From Fig. 16 it will beseen that theinclines ff5 at opposite sides of the cam F5 do not terminate in the same plane axially of the cam, but overlap one another. This is best shown by the dotted lines o in Fig. 16, from which it will be seen that the incline on the righthaud side overlaps the incline on the left-hand side to the extent of the distance between the two lines. Consequently there is no point or instant in the operation of the machine when there is no resistance, because by the action of the cam the traverse of one series of spindles in one direction commences before the traverse in the other series of spindles in one direction terminates.

It will be observed that in the cam F5, which may be considered as a double cam, inasmuch :is its two opposite faces are operative, the points which are in circles at different distances from the center move at different speeds, and as the lever F is tangential to the earn the block orshoef, if made in a single piece, would not bear with its dat faces directly and evenly throughout their whole extent on the cam. To obtain a large bearing-surface of the block or shoef upon the cam, I construct it of a series of polygonal plates, as best shown in Fig. il, said plates being placed side by side and oflittle thickness, and adapted to turn freely upon a pivot or pin, f, by which they are secured in the holder f7, which is here represented as looped to slip over the lever F, and may be secured thereon by aset-screw, fs. As the cam turns relatively to the block or shoe jithefaces of thet-hin plates or sections ofwhich said block is composed each adjusts itself to a true bearing upon the cam, and by the in creased surface thus afforded the wear is reduced and less lost motion produced in the machine.

The preferred method which I have adopted of connecting the link F3 with the lever F* is shown in Fig. 15. I have shown each lever F* as formed with a slot, j, which is continued as a groove, f l", in opposite sides of the lever, and applied to the opposite sides of the lever are blocks or slides f, cach having a tongue or projection adapted to lit in the groovefw, and each having a trunnion, f,upon its outer side. The link F3 is forked or bifureated at the end f 13, so as to embrace the lever Fl, and the slidesfl1 and the two side portions of its bearing receive the trunnions fu upon the outer faces of the slidesffl. By means of a b0lt,f1, inserted through the slotsf in the lever and through the slides f, the latter may be clamped tightly upon the lever, and the freedom for swinging movement of the link F3 on the trunnionsjn2 remains unimpaired.

In assembling the parts the trnnnions f12 of the slides]C11 may be placed in position in the fork fm, and the slides may then be slipped downward over the upper end of the lever F4 until the slotfIJ is 1'eaclicd,wl1en the boltfM is inserted through the slidcsf, and they are clamped solidly against opposite sides of the lever. I have here shown the levers Fl as connected bya spring, flwhich may be used, if desired, although it is not essential, inasmuch as the aggregate strength of the springs 11.* applied one for each spindle will be suiiicient to produce the downward traverse ofthe spindles and to hold the lever F against the cam I will new proceed to describe the stop-motion and also the guides over which the threads are passed in unwinding from the spools E and the brakes which are employed to pre vent such spools from racing ahead. As here represented, the shipper di, before described, is supported by a shipper lever or trigger, I, fulerulned at t', and havin(r upwardly and downwardly extending armsi The arms i are connected by links is with the collar d. on the lower end of the rod or stem Rand it will be readily understood that when the lever or triggerl is swung to the position shown in Fig. 2 the draft upon the links i is directly in line with the fulcrum of the lever, and consequently the shipper di and the whirl DI2 are held in au elevated position with the clutch operative. When, however, theleveror trigger I is swung downward on ils pivotito the position shown in Fig. 3,the clutch is rendered inoperative and the whirl I)2 is moved downward by the action of the spring dl". Connected with the downwardlyprojecting arm i2 of the lever is a stop-finger, it, which is shouldered at irgend, as here represented, passes through a slot in an oscillating knocker mounted upon the rock-shaft- J. As shown in Figs. 2 and 3, the position ofthe slot through which the stop-fingen,4 passes is indicated by dotted linesand the oscillating lr hocker l has a shoulder or projection, i, which when it en- IOO gages the shoulder i5 on the stop-finger v1" produces a draft thereon in the direction of the arrow shown in Fig. 2, and thereby throws ofiI the lever or trigger I and stops the flier. There is a rock-shaft, J, on each side of the machine, each rock-shaft carrying a suitable number of oscillating knockers,I,correspond ing to the number of spindles on that side of the machine, and each shaft has an arm, i7, with which is connected a rod, 11S, operated by an eccentric, i, on the shaft J, as shown in Figrl. The shaft J' receives motion, as-here represented, by a pinion, im, and wheel i from the main shaft D5.

From the above description it will be understood that as long as the stop-finger i* is maintained with its shoulder i5 lifted above or out of the path of the tooth or shoulder i of the oscillating k nocker I the parts will reo main in the position shown in Fig. 2, and the flier will continue its operation.

As usual in machines of this class, the arrangement of devices through which the clutch is shifted to stop the spindle is controlled by i'aller J2, and I have in Figs. 8 and 9 shown the arrangement of fallers which is well adapted for the purpose.

The machine may be employed for doubling silk from two or more spools, E, and winding it upon asingle quill, and. in Fig. 8 I have shown four fallers, J2, as mounted in a fixed frame, J3, one such frame being employed for cach spindle. Each faller J'l consists of a wire having a thread-eye, j, at one end, and at its opposite end secured to a hub, j. The several hubs are journaled upon the pin or pivot ja. The construction of the fallers, however, constitutes no part of the present invention, but is the subject of a separate application for United States Letters Patent, Serial No. 282,179, iiled August 7, 1888. As here represented, the pinjs, which consists of awire, has its end portion, j*,bent lateraily and forked,as

Vatj", to engage one side portion of the frame J3 and to thereby hold the pin j3 in place. Upon the same pin, j, is journaled or pivoted a balanced frame, J4, the back portion of which is made of greater weight, as shown in Figs. 8 and 9, so that it normally maintains the position shown in Fig. 9, and, beingconnected by a wire, j, with the stop-linger t, holds the latter lii'tedout of the path of the oscillating knocker I. Vhen any thread breaks, the faller through which it is passed drops downward upon the frame J* to the position shown by dotted lines in Fig. 9, and by its weight tilts the balanced frame J downward and permits the stop-nger i* to fall into the path of the oscillating knocker I', so that at the next movement of the knocker the shoulder i5 will be caught by the knocker and a pull upon the finger i* in the direction of the arrow (shown in Fig. 2) produced. To secure the most advantageous operation of these parts, I give the wire or rod j a very loose connection with the balanced frame J4, such as may be obtained by ring or loop jl, interposed between the two.

This ring or loop j? gives the rod j more freei dom of movement when the faller drops upon the balanced frame, and this precludes the danger of the said rod failing to let down the shouldered finger it.

I have represented by the balance or balanced frame JL how the ilier of a spindle is stopped when a thread breaks or runs out from the spool E, and I will now describe how the flier is stopped when a quill is full. Extending parallel with the spindle C is a stop-rod, r, which is represented as iitted to slide in a bearing, r', applied to the spindle-bracket B and in a corresponding bearing, r', on the bracket C3. This stop-rod r is held in a normally-elevated position by aspringpd, as shown in Figs. 2 and 3, and it has near the top a shouldi-r or lateral projection, r, which is above the stop-finger i4, and near the bottom a corresponding shoulder or lateral projection, i, which is in the path of an arm, T5, which is on the spindle C and which moves along the rod r. As the spindle C is lowered very slightly at each upward traverse by the quill striking the abutment C", it follows that the arm T5 will at last come to such a point at the lower end of the spindle-traverse that it will strike the shoulder or lateral projection r4 on the stoprod r, and when this occurs the stop-rod will be drawn down against the action ofthe spring r2, and the shoulder or lateral projection r3 will, by striking the top of the stop-finger e, pull the same down, so as to bring its shoulder i5 into the path of the oscillating knocker I. This arrangement of devices for stopping the flier when a quill is full is very desirable, inasmuch as on the rst commencement of the upward traverse of the spindle the stop-rod 1 is relieved of pressure which tends to hold it downward, and its spring r2 will at once raise it off the stop-finger t The thread from the spools E passes downward over guides m, and thence is carried over and under guides m, m2, and m3 in a well-understood manner. As here represented, the several guides m, Ste., are projected from opposite sides of a tensionbracket, K, whereby they are supported, one tension-bracket serving to support the guides for two spindles. Short guides projecting from opposite sides of a tension-bracket, as shown in Fig. l0, are very much more desirable than long guide-rods, such as are more commonly employed, because the thread may be passed endwise over the guides, and the necessityof threading the thread overand underthe guides in succession, as must be done where the guides consist of long rods, is avoided. I desire to make the guides of porcelain, glass, or like smooth and hard material, which will not be cut by the continued passage of thread over them, and the means of securing such guides to and in the tension-brackets is best shown in Figs. l0, 1l, 12, and 13. The guides m are arranged in such position that when the fallers J 2 are raised their thread-eyesj come at about the level ofsaid guides, and byttingthe guides, so that they are adjustable upward and downward IIO in the tcnsionbrackets K, I provide for raising the guides to permit any one or more ofthe fallers J2 being placed behind them, as shown at the left hand of Fig. l, and for then lowering` the guides, so as to hold the faller in such elevated position and keep it off the balanced frame J" While it is idle. To this end each tension-b racket has a slot, k, through which passes a bolt, 7;', as shown in Fig. 12, and to opposite sides of the bracket are applied cup shaped slides k2, through which the bolt k' passes.

Upon the bolt are also placed guidingsleeves or tubuiar guides in, the ends of which enter the cup-shaped slides k2, and are supported therein by springs c, and by tightening the nut or nuts at opposite ends ofthe bolt la the springs may be compressed, so as to hold the cup-shaped slides i" with some considerable pressure against opposite sides of the tensionbracket K. This construct-ion permits of sliding the guides m, which are at opposite sides of the tensioirbracket, upward and downward within the limits of the slot 7c, and after the guide has been raiscdpand the fuller or fallers J'l placed in position behind it, as shown at the left hand of Fig. l., the guide or guides maybe lowered in the slot k, so that they are obtruded in the way of the fallers, and the latter will be held in their upright and inoperative position. As shown best in Fig. 11, the tension bracket K has divided bearings n, formed by a cap or clamp, n, secured by a screw, n?. Inoue of these divided bearings n is clamped a rod, m", to the opposite ends of which the guides nrz are secured each by a screw, mi. In the other divided bearing, n, is clamped a tubular sleeve or casting, m, havinglateral p rejections or branches mhon which are the guides in?. Through the sleeve in extends a bolt, mi. On opposite ends of the bolt or rod are the tubular guides m, secured in place cach by a screw,m. lf the screw n2 be slightly slackened, the tubular sleeve in may turn in its hearing, thereby lowering the lateral branches mT and the guides mi and pro ducing a greater defiection of the thread as between the guides in and nr.

The spools .E are or may be placed upon fixed spindles orjacks p at the upper part of the machine, and I have represented brakes p' as arranged to bear one upon each spool. rIhe term spooh as applied to the parts E, may be considered as including both the core or center,the body and the thread wound thereon; but I prefer that the brakes'p shall bear upon the material wound on the spool,because then as this material becomes reduced and the wei ght ofthe spool is decreased the action ofthe brake p becomes less powerful,inasmuch as it is eX- erted at' a point nearer the center ofthe spool. The brake p is, as here represented, pivoted at one end to a support, p2, which consists of a bracket adjustable circnniferentially about the spindlcp. As here reprcsented,the bracket isjonrnalcd directly upon the spindle,and may be turned thereon and secured in any desired suitable device. I have in Fig. 13* shown several positions into which the brake-supports or brackets p2 may be adjusted and by which the action ofthe brake p" upon the spool may be varied. If the brakesupportsp2 be brought to such position that the brake p'will bear only on the top of the spool, it will have the most powerful effect; but if it be adjusted to such position that the brake bears upon the side of thespool and exerts its pressure thereon in nearl)Y a horizontaliine it Will have much less effect, inasmuch as the gravity will not cause it to press so strongly upon the spool.

I have heretofore neglected to describe the action of the brake, whereby the [iler-hub is stopped when the clutch is thrown off, and which is best shown in 4. On one or both of the yielding jaws d, which compose one ofthe clutch members, are inwardly-projecting pins d1, which project through lateral openings in the Hier-hub D, and the innerends of Which are in close proximity to the fixed tube C', on which the flier-hub turns. W'hen the fork (is is lowered and the whirl D2 is drawn down, thereby lowering the conical spreader d5 and permitting the jaws dito move toward each other under the action of the spring (1*, the pins d13 are pressed against the surface of the lined tube 0 and constitute a brake for arresting the movement of the dier.

In Fig. 7 I have described a modification of the clutch, in which two spring-arms are secured at one end to the llier huh D and at their other ends are formed to bear against a conical surface, d5, on the whirl D2, and at the base of which conical surface is a pin or lateral projection, df'. When this whirl is raised, the clutch will act similarly to that shown in Fig. 2, motion being imparted to the tlier D through friction, and subsequently through the positive interlocking of the projection d" with one of the springs d2.

The slots j, or a corresponding series of holes, provide for varying the length of traverse niotion received from the cam F5.

I have before neglected to describe the man ner of securing the eyes in the fallers J2. rIhese eyes may he of porcelain, and the end ofthe wire may be bent to forni a hoolnjs, as shown in Fig. 8*, which at its beak j is niade to constitute a slight spring. l When the eye j is placed as shown in Fig. 8*, a turning niotion in the direction oi' thearroviT thereon will force the eye into the hook and it will bethere retained. This is particularly useful, because after the eye is in place in the hook it will be free to play or move therein, but cannot escape therefrom.

In connection with my eighth claim I am aware of French Patent to Tardy, No. 8,783, of June 4, 1842, and I do notseek toinclude in my invention anything shown in that patent. That patent shows, among other things, a thread-guide formed of wires twisted together and separated at the upper portions, so as to produce a fork which grasps the porcelain or osition b f means of a setscrew 9 or other i other 0nido-eve, thronvh which the thread is j 7 7 D u D IOC) directly conducted. My ierarm D is astrip of thin metal slotted from one end inward at d to forni the two elastic fingers, which embrace between them the guide-eye, and may either of them be deflected from its normal plane to facilitate the insertion of this guideeye thereinto and its removal therefrom.
