YARN OR THREAD WlNDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 558,314, dated April 14, 1836. Application filed ay 11, 1895. Serial No. 548,912. (No model.)

To all whom it may concern:

Be it known that I, EPPA H. RY ON, of Waltham, county of Middlesex, State of Massachusetts, have invented an Improvement in Yarn or Thread Vinding Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object the production of a machine for winding yarns or glazed threads upon a receiver of preferably conical form and'made of any suitable material, the receivers being positively rotated and arranged in adjacent pairs.

A thread-guide delivers a yarn or thread to each receiver of the pair at a point between them, and the said receivers are rotatably mounted in separable bearings, whereby they are mutually separated as the diameter of the wound mass of thread or yarn on each increases, the said wound masses being in rolling contact with each other.

It is very desirable for many reasons to wind yarn or thread into conical masses, and it is well known that in the rotation of a cone the surface speed decreases from the base toward the apex of the cone, and when such a conical surface is being rotated by a cylindrical surface the yarn or thread laid upon the cone toward its base is subjected to such strain and abrasion as to produce in many classes of yarns and threads cuts or weak thin places, which is highly objectionable. This has been overcome in part by interposing between the cone and the driving-roll an intermediate roll made in sections or rings, loose upon a shaft, which is rotated by the driving-roll, the rings slipping more or less upon the shaft, according to their position toward or away from the base of the cone. This construction necessitates the use of sectional rolls, which are expensive, and but one cone can be driven by each roll, While in this invention I have obviated not only the format-ion of cuts or abrasions, but also the use of section-rolls, by winding the conical masses in pairs, with their surfaces tangent to each other and their axes converging toward the apexes of the cones. Each cone thus serves as a prcsscr-roll for its fellow, laying the thread or yarn hard and evenly thereupon with a uniform friction and strain from one to the other end of the cone, the two masses of yarn increasing in diameter in the same ratio, and opposite or adjacent portions of the two cones have a constant speed ratio from base to apex. ing the finest or most delicate yarn or thread can be wound into hard compact masses without the least abrasion, strain, or friction, obviating completelycuts or weak places.

The thread or yarn is delivered to each mass close to its point of contact with the other mass, means being provided for traversing the threads or yarns during the winding.

As the wound masses of thread or yarn increase in diameter they mutually press their supports away from each other, and by a very simple device the counteracting pressure upon them may be regulated to any desired degree.

I have provided a stop-motion, controlled by the slackening or breakage of either yarn or thread, to automatically stop the rotation of the supports or spindles, and means are also provided for stopping the machine when a predetermined length of yarn or thread has been wound.

Myinvention accordingly consists in a machine for winding thread or yarn constructed and arran ged as will behereinafter described, and particularly pointed out in the claims.

Figure 1 in elevation, for the greater part, represents a winding-machine embodying my invention, but one pair of spindles and their cooperating mechanism being shown, the parts above the line a: 00, Fig. 3, being shown in elevation. Fig. 2 is a View of the parts shown in Fig. l at the left of the line 0: m, the driving-pulley being omitted entirely. Fig. 3 is a top or plan view of the machine shown in Figs. 1 and 2, the means for controlling the stoppage of the winding when a given length of yarn or thread has been wound being omitted for the sake of clearness. Fig. 4 is a side elevation of the thread-guide with its supportin section and the masses of thread or yarn indicated by dotted lines. Fig. 5 is a side view, with the cover-plate removed, of the measuring and controlling mechan- By this method of windism; and Fig. 6 is a transverse sectional View thereof.

I have herein illustrated the machine as adapted for winding conical masses of yarn or thread, and, referring to Figs. 1, 2, and 3, the front and back frames A A are connected by parallel cross girths or braces B B, of suitable shape and location to sustain the operative parts of the machine, it being understood that the frame may be of suitable length to support any desired number of pairs of cooperating spindles.

The braces B B form tracks or guides, upon which are mounted bearings a a and I) b" for spindles s and s, the under sides of the bearings being grooved to embrace the tracks, as clearly shown in Figs. 1 and 2, to prevent lateral displacement.

Each bearing has, as herein shown, a boss 6 thereon, slotted at its inner side, as at 7, Fig. 1, to form open seats for the journals of the spindles, whereby they can be readily inserted in or removed from the seats, and when conical masses are to be wound the seats in each pair of adjacent bearings are inclined toward each other, as shown best in Fig. 3, so that the spindles s s when mounted therein will converge.

Hubs c on the braces B B serve as guides for two vertically-movable slide-rods c, to which are rigidly secured substantially A- shaped yokes 0 the inner faces of the yokes engaging projections, preferably rolls, as 20, on the outer sides of the bearings, each yoke cooperating with the two bearings at the same side of the machine.

A weight w is attached to each slide-rod to normally d raw the yoke secured thereto downward against the rolls 20, thereby tending to move the bearings comprising each pair toward each other and resisting their separation proportionally to the weight and the angle formed by the yoke-arms.

To lift the slide rods 'c and their yokes quickly and in unison, the said rods are con.- nected by cords e or other suitable flexible connections to a treadle T, pivoted to the frame at T, the connections passing over sheaves 0 secured to the braces, whereby depression of the outer end of the treadle will raise the slide-rods and lift the yokes c from the bearings.

From an inspection of Fig. 1 of the drawings it will be obvious that separation of the bearings of each pair will, through the projections or rolls 20, acting on the inner sides of the yokes c raise the latter gradually, while a constant tension is maintained upon the bearings, and byincreasin g or decreasing the weight "w the resistance to such separation of the bearings can be regulated with great nicety.

Receivers r1", shown herein as tapering or conical in shape, are slipped upon the spindles s s to rot-ate therewith, and upon these receivers the thread or yarn is wound, and at the beginning of the winding operation the receivers will be substantially tangent to each other to receive the threads or yarnst t, and as the latter are wound upon the two receivers the gradually-increasing masses of yarn will, acting upon each other, press thesupporting-spindles away from each other, the bearings sliding on the tracks or braces 13 B.

To deliver the threads or yarns to the receivers close to their peripheries and as near as possible to the line of contact of the two masses of yarn or thread G O, the yarns are led through suitable drop-wires d (1, up over the preferably grooved sheave D, (see Figs. 1 and 2,) supported on a suitable overhanging arm A of the frame, and thence down through guide-eyes e e of a traveler e (shown separately in side elevation in Fig. 4,) the traveler being provided with a delivery-nose e provided with a guide-eye a through which the yarns or threads t t are passed in 0pposite directions to be laid upon the masses of yarn or thread (3 O.

The under side of the upper portion of the traveler is convexed at e to rest in a longitudinal trough or groove f in the top of a transverse support 1", mounted upon the upturned ends g of standards, provided with hubs g to embrace and slide upon the sliderods 0, the standards being provided with preferably adjustable collars 9 upon which thesupport f rests.

The traveler e is moved back and forth on its support f by suitable mechanism, to be described, to traverse the yarn from one to the other end of the receiver, and it will be obvious that as the diameter of the Wound masses increases the delivery-nose e of the traveler must be slightly raised in order to clear the yarn, and for this purpose I have secured, preferably to the hubs g of the standards, laterallyextended yokes the arms of which make an obtuse angle with each other, and which rest upon the projections or rolls 20 on the separable bearings. As the said bearings are separated for the i11- crease in diameter of the yarn masses the rolls 20, acting upon the yokes 9 will tend to raise them slowly to thus lift the standards g, and thereby the traveler e to maintain the guide-eye e at the proper point between the yarn masses, the latter thus controlling, automatically, the position of the traveler relative to their line of contact.

The traveler is slotted at its upper end at 6 (see dotted lines, Fig. 4) to receive therein the reduced end of an arm 6, longitudinally movable on and supported by a bar 6 secured to the braces B B, and retained on said bar by a suitable cap-plate c said arm below the bar 6 being provided with a pivoted foot c", which enters a crossing groove E in a suitable cam-roll E, mounted on a shaft E rotatable in suitable bearings B B on the framework. Loosely mounted upon said shaft is a belt-pulley H, driven by a belt E on a pulley E on the main driving-shaft (See Fig. 1.)

As the cam-roll E is rotated the crossing groove E therein will move the arm a back' and forth on its support to in turn actuate the traveler e and traverse the yarn, and to avoid shock and to assist the traverse mechanism in changing its movement from one to the other direction spring-buffers 50 (see Figs. 2 and 3) are located at the ends of the groove f.

The belt-pulley H is mounted loosely on the shaft E and its hub it forms one member of a clutch, the other member it being longitudinally moyable on but rotatable with the shaft E so that by movement of the member 77. into operative or inoperative position the shaft and cam-roll E will be rotated or remain stationary, as desired.

Fast on the shaft E and beyond the pulley II is secured a preferably grooved pulley or sheave S about which is passed an endless band or cord .swhich is also passed over grooved sheaves S and S on the inner ends of spindles s and s, respectively the manner in which the band is passed over and about the sheave being clearly shown in Fig. 1, the band passing from the sheave S to S, then down in a loop or bight up over the sheave S from the outer side, then back to the sheave S and in order to maintain the band taut at all times and yet to allow separation of the sheaves S S an idler-sheave S is mounted upon the band at its loop or bight and has attached thereto a suitable weight W, which constantly takes up any slack in the band and also aids in holding the inner ends of the spindles toward each other.

By connecting the sheave S with the shaft E the traverse mechanism and the rotating device for the spindles, just described, will always operate or cease to operate in unison.

It is of course necessary to provide means for automatically stopping the apparatus upon breakage or undue slackening of the yarns, and for this purpose I have provided devices controlled by such slackening or breakage to render the clutch mechanism h h inoperative upon such a change in the condition of the yarn, one or both.

The drop-wires d d are preferably enlarged or weighted, as at 30, and pass through holes in a guide-plate (Z and below the drop-wires and in their paths when not upheld properly by'the yarn I have extended a plate or shelf (1 mounted on an arm (1 pivoted to the frame at d and notched or shouldered at d to normally engage the toe of an arm d fast on a rock-shaft d supported in suitable bearings 15, and extending beneath one of the braces, as B, the front end of the rock-shaft having fast thereon a second arm (1 forked at its lower end to engage and operate the member h of the clutch in usual manner.

The casting to which the arm d is secured is provided with an extension d upon which is adjustably mounted a weight 10 to normally maintain the notch or shoulder d lifted to engage the toe of the arm (1 and thus maintain the clutch in operative position.

An arm c1 secured to the rock-shaft d and extended at an angle to the arm d is also provided with a weight w to maintain the toe of the arm cl in engagement with theshoulder dfland to correspondingly move the clutch into operation to start the machine I have provided the arm (1 with a lifter-bar d, (shown best in Figs. 1 and 2,) whereby the operator by raising'the latter turns the rock-shaft to cause the rounded under side of the toe of the arm d to pass over the shoulder d and to throw the clutch into operative position.

It will be obvious if one or the other of the two yarns i t slackens or breaks that its dropwire will fall upon the shelf d depressing the latter and tipping its arm 01* about its pivot d withdrawing the shoulder d from the toe of the arm (1 and permitting the rockshaft under the influence of the weight 10 to turn or rock and move the clutch member it out of engagement with the member h, thus automatically stopping the traverse mechanism and the rotation of the spindles, and then the operator can remedy the trouble and by raising the lifter-bar 01 will throw'the clutch into operative position to start the machine.

While not absolutely necessary it is desirable to automatically stop the winding after a predetermined length of yarn or thread has been wound upon the receivers, and I have herein shown one form of mechanism for controlling the machine according to the length of the yarn wound.

The sheave D, mounted at the'upper part of the machine, is rotated by the yarns or threads as they pass from the drop-wires to the traveler, and to one end of the shaft 70 of said sheave I have secured a disk 70, having thereon a wrist-pin k to engage at each revolution of the sheave a pawl-carrier it longitudinally movable in a bearing m, formed in the case M of a suitable counting mechanism. A pawl 70* is pivoted to the pawl-carrier k within the casing and controlled by a suit-' able spring 70 which also keeps the carrier in the path of the Wrist-pin 10 the pawl engaging the teeth of a series of ratchet-wheels m m m loosely mounted side by side on a shaft m in the casing M.

The ratchet wheels or disks are provided with a diiferent number of teeth, the number of teeth in the ratchet m being one less than those of the disk m, and the disk m has one less tooth than has the disk m and as the pawl It engages the teeth of the three disks simultaneously it will rotate the disks through different arcs at each-reciprocation of the pawlcarrier, so that the disks m and on will gain continuously on the disk m. If, for instance, the diameter of the sheave D is six inches and the disks m m m have, respectively, thirty-nine, thirty-eight, and thirty-seven teeth, it will take about fifty-four thousand eight hundred and thirty-four revolutions of the sheave D to bring the three ratchets in the same relative position as they were upon starting. I make use of this by slotting all three of the disks radially, so that when the slots are in alinement, as in Figs. 5 and 6, a plate a on the end of a shank 77., extended from the top of the casing M, may drop into them. The shank n has attached to its outer end an arm 02 (see Figs. 1 and 2,) to which is secured a depending rod 12 the lower end of which is slightly above the shelf d when the shank n is raised into the position shown in Figs. 1 and 2 and in dotted-line position, Fig. 5, such position being maintained while the masses of yarn are being wound.

When the desired number of yards of yarn has been wound, the slots in the three disks will be again brought into alinement and the plate '12 can drop into full-line position, Figs. 5 and 6, into the slots, thus depressing the rod 97, and causing its lower end to act upon the shelf 61 to release the stop-motion mechanism to stop the machine automatically.

In order to obviate resting the plate a on the toothed peripheries of the disk during the winding, I have cut away the lower edge of the plate to leave projections a which normally enter between the disks m m and m m and rest upon annular shoulders formed thereon, (clearly shown in Fig. 6,) so that the plate n will not be vibrating all the time that the ratchet-disks are being moved forward step by step.

WVith the dimensions hereinbefore given about twenty-eight thousand yards of yarn or thread may be wound upon each receiver.

It will be obvious that other registering mechanism may be used in this connection to actuate the stop-motion after a predetermined length of yarn has been Wound, and my invention is not limited to the particular re istering and controlling mechanism shown herein.

From the foregoing description and the drawings it will be evident that each mass of yarn of the pair will act upon its fellow as a presser-roll to wind the yarn or thread in a hard compact mass thereon, the two wound masses increasing in size in unison, and as the surface speed of adjacent parts of the two masses is equal there can be no abrasion or strain upon the yarn or thread at any time, thus obviating absolutely the formation of any cuts or weak places.

By my invention I am enabled to wind conical masses of yarn or thread with much greater uniformity and density and in larger masses than has heretofore been possible.

It will be obvious that by mounting the spindles in parallelism and using cylindrical receivers the yarn may be wound in cylindrical masses, the mutual action of the wound masses of each pair being precisely the same.

My invention is not restricted to the precise construction and arrangement of parts herein shown, as it will be obvious that the same may be modified or rearranged without departing from the spirit and scope of. my invention.
