MACHINE FORWINDING YARN FROM CHAINS ONTO FILLING-BOBBINS.

SPECIFICATION forming part of Letters Patent No. 573,288, dated December 15, 1896..

Application filed August 13, 189 i- To aZZ whom it may concern.-

Be it known that we, HERBERT LEANDER PRATT, of Lewiston, in the county of Androscoggin and State of Maine, and CHARLES THOMAS UPTON, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for W'inding Yarn from Chains onto Filling-Bobbins, of which the fol- IO lowing is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention relates to machines for winding yarn directly from the chain onto the tilling-bobbins for use in the shuttles for weaving, and thereby dispense with the spooling or beaming of the yarn.

In winding yarn, after the same has been dyed or bleached, directly from the chain onto the filling-bobbin the'individual threads of the chain have to be separated and connected each to its respective spindle. The machines for winding the yarn on the cop or bobbin have usually eight banks of spindles and contain as many spindles as there are threads in the chain. As the cops or bobbins must be wound in conical layers to the very end of the same and must form a well-wound nose at the end to make the cops or bobbins perfect and prevent stripping when used in the shuttle in weaving, it is essential to the practical and successful use of these machines that the tension on all the threads of the chain shall be uniform and all soft places in the cops or bobbins avoided.

The yarn during the process of doubling, dyeing, and splittingbecomes more or less entangled, and broken ends frequently occur in the chain. To successfully wind this yarn 40 directly on filling-bobbins, the operation of separating the yarn strands of the chain requires to be under the constant control of the operative, so as to prevent imperfect yarn passing through the machine. In these machines the successful operation of all the spindles receiving the yarn from one common source (the chain) requires mechanical refinements and automatic self-adjustments that in the ordinary spinning, twisting, or wind- Serial No. 520,132. (No model-l ing machines, in which each spindle is sup plied from an independent source, are either unnecessary or not of such importance as would make the machine useless without them. In machines for winding the thread directly from the chain on the cop or bobbin the great saving in time, labor, and mill-room has been made possible by close attention to the details of the machines, by which the uniform speed of the spindles, the accurate adj ustment of the tension of the yarn, the accessibility of the spindles in doffing, the starting of the machine to wind on the new bobbins after dofiing, the uniform and regular laying of the yarn on the cops or bobbins, the protection of the yarn from floss and fiber, and the other advantages are secured.

The invention consists in the peculiar and novel constructions and arrangements of the machine, as will be more fully set forth liereinafter and more particularly pointed out in the claims.

Figure 1 is a view of the end of the winding-machine and the chain-tension machine which delivers the yarn under the required tension to the winder. Fig. 2 is a vertical sectional view of the yarn-winding machine. Fig. 3 is a front View of the machine, in which only two vertical rows of spindles are shown, the other spindles being left off so as to show the construction of the machine more fully. Fig. 4c is a top view of the delivery-rolls, showingthe rods for concentrating the threads when dotting in the normal posit-ion. Fig. 5 is the same view as Fig. 4, showing the threads concentrated for doffing. Fig. 6 is an end view of the pinion connecting the cop-building mechanism with the driving mechanism, showing part of the gear and the stop-link by which the pinion is secured. Fig. 7is aview of the shaft and pinion and a sectional view of the stop-link shown in Fig. 6. Fig. 8 is a a view of one of the spindles, partly in section. Fig. 9 is a skeleton front view of the machine, showing two vertical rows of .spindles and guide-eyes placed much farther apart than they are in the machine, so as to more clearly show the paths of the severalthreads from the top rolls to the guide-eyes and the spindles and placed in the rear of the rail in front and above the same, so that the spindles form inclined bank or slope and can each be readily;

reached by the attendant for the purpose of doffin g or piecing.

The numbers 1 designate the end frames, and 1 the central frame,of the machine,which form the supports to which the bolster-rails 2 2 are secured, and also the supports for the driving cylinders and the mechanism by which the various parts of the machine are operated. The central frame 1 is an important feature. The large number of spindles require to be so closely grouped together that the driving-cylinders can be only of limited diameter, and therefore require a central support. The bolster-rails 2 each support a line of spindles.

In Fig. 3 only two spindles are shown as secured to each bolster-rail.; but in the machine as used the spindles are placed along nearly the whole length of the bolster-rail as close together as the practical working will permit.

The numbers 3 represent the spindles, the construction of which is more clearly shown in Fig. 8 and will be more fully described hereinafter.

Numbers 4 designate the bobbins or quills on which the yarn is wound in the shape of acop ready for use in the loom-shuttle.

5 designates the driving-cylinders turning in the bearings 6 in the ends 1 and center frame 1 of the machine. Each one of the cylinders 5 is made to operate two lines of spindles. The bands 7 7 pass partly around the driving-cylinders 5 and the whirls of the spindles 4, so that for a machine with eight lines of spindles four driving-cylinders are used.

The machine is driven by means of a belt communicating power from a prime motor to the pulleys 8 9, 8 being a pulley secured to the driving-shaft and .l a pulley loose on the shaft. The power is transmitted from the fixed pulley S, by means of the gears 10 and 11, to the main driving-cylinder 5. On the opposite end of this main driving-cylinder 5 the gears 12 transmit the power to the other driving-cylinders 5, so that all the drivingcylinders, and, by means of the driving-bands 7, all the spindles revolve with the same speed. To the projecting end of the shaft of main driving-cylinder 5 the sprocket-wheel 13 is secured, and from the same the chain 11 passes under the flanged gravity-binder 14: and over the sprocket-wheel 15, secured to the shaft of the roll 18, from which, by means of the gears 17 motion is transmitted to the roll 16. The top roll 10 rests on the two rolls 16 and 1S and turns with them. The iron center of this top roll 19 is very slender to allow it to deflect to conform to the deflection in rolls 16 and 18, and is covered with rubber or similar elastic material to secure a firm bearing at all points of the surface of the rolls 16 and 18, and is then covered with felt or otherfibrg us naterial to enable it to take u pTny broken threads. On the top of the machine, in the rear of the rolls 16, 18, and 19, is suspended the reed 20 by the rods 20', connected with the upper end of the posts 20 secured one to each end of the machine, or, when convenient, from the ceiling of the room in which the machine is located. This movable suspended reed 20 is specially made for this work and is equally spaced over its entire length to conform to the space of the spindles.

The swinging reed 20 can be moved backward and forward by the operative to facilitate the separation of the'threads of the chain, and when the strain on the reed is excessive the operative stops the machine. \Vhen the operative releases the reed, it swings toward the top rolls until it rests on the table 56. A bench is usually placed in front of the foottreadle 36 on which the operative stands, so that when the operative, whose hand is on the swinging reed, feels that excessive strain is exerted on the reed he can stop the machine with his foot.

WVhen the threads require to be bunched to facilitate doffin g, the reed 20 is moved back to facilitate the bunching of the threads. The point at which the rods 20 are pivotally connected with the posts 20 is in practice much higher above the machine, and the reed swings through an arc of greater radius than that shown in the drawings. The rods 20 are connected to eyes on the upper bar of the reed, so that the reed may swing independent of the rods.

()n the projecting end of the shaft of the lowest driving-cylinder the pinion 22, provided with a groove, is connected with the shaft, which has a spline and turns with the same while in the normal geared position, and

is held in that position by the stop-link 22', which rests on the shaft between the nut on the end of the shaft and the pinion 22, so that when the stop-link is removed the pinion 22 can be drawn outward and the pinion disconnected from the gear 22 thereby disconnecting the spindle-driving mechanism from the cop-building mechanism and permitting the winding back and independent adjustment of the cop-building mechanism. The chain 23 connects the sprocket-wheel on the shaft of the gear 22 with the sprocket-wheel 24, from which motion is imparted by means of gearing to the cop-forming mechanism by which the reciprocating guide-wires 26 are operated. These guide-wires are secured to the horizontal rods 27, extending from end to end and are supported on the inclined bars 27, which are in turn secured to the upright supports 29, the feet of which rest on the levers 30, which levers are provided with the balance-weights 31, by which the cop-building guide-wires, the horizontal rods, and the frame in which the rods are carried, as well as the upright supports 29, can be counterbalanced or slightly overbalanced, so that the cop-building mechanism can operate the same with the least practical strain. The counterbalanced levers 30 are placed near each end and the middle of the machine and are connected so as to be operated together by the cop-building mechanism, as is shown clearly in Fig. 2.

To secure the most economic results, the machines require to be of such lengths that the greatest number of spindles that can be attended to by one attendant are massed in one machine. To lay the yarn on all the quills or bobbins uniformly, the guide-wires must all move together. To secure this uniform motion of all the guide-wires, we construct a rigid frame in which the horizontal rods 27 are firmly secured to the inclined bars 27 27 27, near the center of the machine on each side of the center, and also secure the ends of the rods 27 in the end bars 27 27, the whole forming a rigid frame which is sup ported 011 six'vertical rods 29, three near the front and three at the rear.

The cop-building mechanism used in this present machine is the same as that described in Patent No. 416,495, granted to us December 3, 1889. The mechanism by which mo tion is imparted to the cop-building mechanism consists of the cam 40, revolved by means of the-shaft carrying the sprocket-wheel 24 and intermediate gears 49 and 50. (Shown in Fig. 2.) The edge of the cam 40 bears against a stud 51, projecting from the sideof the horizontal lever 41. On the opposite side ing from the said lever, is the pulley 42, having the worm-gear 45 secured to it. To the pulley 42 is secured one end of the chain 43, which, passing over a sheave, is connected with the arm 44, mounted on the lever 30.

The cam 40 in the cop-building mechanism shown in the drawings is a circular disk secured to the shaft at one side-of the center, so as to impart in revolving reciprocating motion to the horizontal lever 41. A heartshaped cam may be used, so as to impart a quicker motion to the guide-frame in one direction, preferably a slow downward motion, so as to lay the yarn on the quill or bobbin in close spirals, and a quicker upward motion,

so as to bind the yarn by an open spiral binding-thread. The motion of the lever 41 is transmitted by the chain 43, secured to the pulley 42, to the levers 30 and by the said levers to the inclined frame 27, upright supports 29, and rods 27,1 carrying the guide wires, which are reciprocated Vertically to guide the yarn on the conical base of the bobbin, thus layin g one layer of yarn as the horizontal lever 41, operated by the cam 40, moves upward and another as it moves downward, the weight of these reciprocating parts being counterbalanced or nearly counterbalanced by the weights 31.

By the use of the center frame 1 great stability is secured for the rails 2, on which the spindles are supported, and the driving-cylinders also are more firmly held by being journaled in bearings supported'in the central frame. To secure the same stability to the mechanism by which the cops are built and the yarn'is laid on the quill or bobbin, we have secured the rods 27 which carry the guide eyes or wires together and formed them into a substantial frame by the use of the three rails 27 and the end rails 27 and have supported this frame on three sets of counterbalanced lifting-rods 29.

In a machine for winding yarn directly from the chain where the spindles are ar ranged in. sloping banks close to each other it would be difficult to remove and replace the quills or bobbins, as the threads of yarn practically cover the whole of the front. To facilitate the doffing of the spindles, we support in suitable guides in the rear of the top rolls and close to the roll 16 the rods 55 and 55, as shown in Figs. 4 and 5. On these rods 55 and 55 we place vertically-projecting pins, so that the yarn of each two vertical rows of spindles passes between two pins, one on each of the rods, and we provide suitable means for shipping the rods 55 and 55, so that all the threads, namely, in a machine of the present construction, sixteen threads, leading to two vertical rows of spindles are brought or bunched together, as shown in Fig. 5, be tween the two rows of spindles, and so leave wide spaces between the bunched threads of yarn and free access to the spindles for dofling. of the horizontal lever 41,'on a stud project- In connection with the devices for bunching the. threads of yarn of two vertical rows of spindles between alternate vertical rows'of the spindles we place the guide eyes or wires for dofling the width between the bunched threads is the width of two rows of spindles, forming a wide path which permits the taking off of the filled bobbins and the replacing of the new empty bobbins.

We do not wish to confine ourselves to any particular means for operating these rods 55, but have shown them each atone end pro vided with a rack and have shown a pinion between the racks, so that by turning the pinion the bars may be operated. These. bars 55 may be shipped or operated by ha-ndor by any other suitable'means.

Practical experience has demonstrated that the reed 20 requires to be placed near the top rolls, so as to accurately guide the yarn onto the delivery-roll 18 and from the same to the spindles; but in bunching the yarn in dofling this close proximity of the reed to the top rolls interferes with the bunching. We therefore suspend the reed 20 by the rods 20 at each end from the vertical posts 20 extending at each end above the end frames of the machine, so that the operator on preparing for dofting, before he stops the machine, pushes the reed 20 backward from the position shown in Fig. 4 to the position shown in Fig. 5.

The spindles 3 are driven at a speed sufficient to wind all the yarn delivered to them at the smallest diameter of the quill or bobbin and to permit the automatic adjustment and uniform tension at all diameters of the quill or bobbin. The bobbin is not secured to the spindle, but to the bobbin-holder 4, which is loose on the spindle and is supported 011 the whirl 3, a friction-disk 3 of felt or other suitable material, being placed between the whirl and the bobbin-holder. The frictional resistance can be regulated by increas ing or diminishing the diameter of the friction-disk 3 thereby extending the frictional resistance farther from the center or bringing the same nearer to the center of rotation of the spindle, and the quills or bobbins will be wound as close and hard as may be required.

The bobbin-holder 4 consists of a lower circular flange 4, from which extends upward the cylindrical waist 4*, which curves outward to the upper flange 4, of somewhat larger diameter than the base of the bobbin. The bobbin-holder serves to hold the thread during dofling, as will be more fully set forth hereinafter.

The machine is covered in and protected from loose ends and floss, detached by the thread passing through the reed 20, by the table 50, whichextends over the length of the machine and the whole of the width, except the front portion protected by the top rolls. The table 56 forms the support of the end guide-bars 5G, placed on each end of the machine to form the end guides for the swinging reed 20.

The chain-tension device is placed in the rear of the machine and consists of the frame 57, in which the two cylinders 58 and 59 are journaled. Each of these cylinders is partially surrounded by a friction-strap, one end of which is secured to the frame 57 and the other .to one of the levers (i0, pivotally connected at one end to the frame 57 and provided at the other end with an adjustable weight. The chain 61 passes through the eye 62, under the roll 63, over the weight-roll 64, and then between the rolls 63 and 64, under the cylinder 58, then over the cylinder 59, thence two or more times around both the cylinders 58 and 59, and then over the roll 65. The chain is now split and the individual threads passed through the reed 20 over the top rolls and to the respective spindles.

These machines are usually built of greater length than the proportional length shown in Fig. 3, and as six, eight, or more lines of spindles are banked above and behind each other a very large number of spindles may be used and easily overlooked by the operative.

The machine is started and stopped by shipping the driving-belt to or from the driving-pulley by the shipper 32, which is connected by means of the bell-crank 33 with the rock-shaft 34, to which the levers 35 are securely fastened and provided at their end in front of and extending the whole or nearly the whole length of the machine with the treadle 36. The weight of these levers and connecting-board is counterbalanced by the weight 37, adjustably secured to the lever 38, which is fastened securely to the rockshaft 34. g

In a machine for winding yarn from the chain onto filling-bobbins such a very large number of threads have to be separated from each other and guided to the bobbins that it becomes difficult for one operative ,to overlook the separation of the threads and the winding on the bobbins. The vibrating threads passing through the swinging reed cannot be readily seen without a suitable background. The table 56 forms such a background and is used for this purpose, as also to prevent the loose ends separated by the reed from falling on the threads passing from the top rolls to the bobbins. In these machines, where as many as three hundred and seventy-six (376) spindles are used, it is impractical to connect all the ends after doffing with the new bobbins. Some arrangement is therefore required by which all the ends are automatically connected with the new bobbins. The arrangement which we preferably use consists in the bobbin-holder 4 and the arrangement for disconnecting the spindle driving mechanism from the copbuilding mechanism shown in Figs. 6 and 7. When the bobbin is completed, the stop-link 22 is removed, the gear 22 is drawn outward away from the splineby whichit is secured to the shaft and thereby disconnected from the gear 22, the machine which has been stopped is started and turns all the spindles, the frame carrying the guide-eyes is depressed until the yarn is wound around the waist 4 of the bobbin-holder 4, the belt is now shipped and the revolution of the spindles stopped, the yarn is bunched, as before described, so as to give free access to the bobbins, and the operative quickly jerks the bobbins off the spindles and, by reason of the corners of the upper flange 4 of the bobbin-holder 4, the yarn easily breaks.

\Vhen the new or empty bobbins have been placed on the spindles,the driving mechanism is started to drive the spindles, the frame supporting the guide-eye is raised, and the threads connected with the bobbin-holders.

are guided onto the bottom of the cone of the bobbins, the machine is stopped, the gear 22 is pushed in to connect it with the gear 22 so as to connect the cop-forming mechanism with the spindle-drivin g mechanism, the machine is started, and a new set of bobbins is wound. By this arrangement the operation of the machine is practically continuous, the savim eitected is large, as by reason of the improvements incorporated in the machine the operative has a complete oversight and control of the large number of threads as the yarn is delivered to the top rolls, as well as over the whole bank of spindles, being able to stop and start the machine while his eyes are on the yarn coming from the chain as well as 011 the yarn being wound on the spindles. Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.
