BUILDING-MOTION FOR SPINNING-MACHINES.

Specification of Letters Patent.

Patented Feb. 25, 1913.

Application led April 25, 1910. Serial No. 557,354.

To all whom it may concern Be it known that I, DUnEm. O. Pease, a citizen ofthe United States of America, and resident of Hampden, in t-he county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Building-Motions for Spinning- Machines, of which the following is a. full, clear, and exact description.

This invention relates to spinning machines, and more especially to that class in which a traverse is employed for the purpose of laying-on or building-up the yarn on the bobbins which may be disposed at opposite sides of the frame and which are driven at a high rate of speed, these machines being generally known as ring-spinning frames.

The invention is especially applicable to a machine in which the bolster-rail or spindlesupporting rail is vertically movable so as to move the bobbins or spindles through and relatively to the ring-rail which latter will remain stationary, so that consequently the distance between the drawing-rolls or the thread-guides and the ring-travelers will remain constant, and therefore, eliminate any Variation in the twist which is to be given to the yarn preparatory to its being laid on the bobbin.

The object of the present invention is to provide such means of traversing or reciprocating the spindle rails of spinning frames as will obviate ditliculties which have been experienced to such a degree in the past as to have rendered such devices operatively defective and of little of no value commercially; and to combine with such improvements a further device or attachment which during the formation of the base or butt of the bobbin will enable the traversing or reciprocating motion of the spindle rail to be initially short and gradually lengthened until the base of the bobbin of required shape has been formed, when the spindle rail has its normal length of traverse, and so continues until a complete bobbin has been formed.

Previously constructed spindle rails have been traversed or reciprocated by the common or conventional method known as a rocking arm. This has never been successful for the reason thatl the spindle rail is of so much greater Weight than the ordinary ring rail that anv so far discovered method of balancing has necessitated such heavy weighting that the frictional resistance has rendered it impossible to build a frame that has, been commercially salahle. The present invention overcomes these defects by reason of the fact that the two opposite rails are mounted upon pillars with very short .and very loosely fitting slides. They are lifted or pulled upward instead of belng pushed upward by the conventional rocking arm. This method reduces the frictional resistance of the reciprocating operation to such a material degree that the frames can be builtl of a length which enables them to be sold on a commercially successful basis.

Another improvement attained by the use of the present appliances consists in the fact that the reciprocating motion is always of the same length to whatever length it may be desired to build the bobbin, whereas in the old, method the longest point in the reclprocation is usually so arranged and set that it is in the middle of the bobbin, becoming shorter toward the base, and again shortening at the top of the bobbin.

The common practice in building` frames of this description is to have two opposite spindle rails mounted upon fixed vokes which extend across the frame making what may be described as a cradle, carried upon four perpendicular pillars, two on each side of the machine; and'simultaneously lifted by a so-called builder lever which is operated by means flexibly connected therewith.

A further result of my device is to neutralize the inward pull of the Spindle bands and enables me to use the above mentioned short and loosely fitting sleeve which merely acts as a guide. Past methods have employed a heavy and cumbersome method of slides in order to overcome the inward pull of the spindle bands.

The invention has been fully illustrated in the accompanying drawings in which similar characters denote similar parts, and in which- Figure l is a side view of the spinning frame illustrating merely the ring-rail and also the bolster-rail, together with its actuating mechanism. Fig. 2 is a horizontal section on line 2, 2 of Fig. 1. Fig. 3 is a vertical section through the frame illustrating the bolster-rail actuating devices. Fig. 4 is a diagrammatic view showing the manner in which the spindles on opposite sides of the frame are driven from a single device. Fig. represents on an enlarged view one end of the bobbin frame mechanism. Fig. 6 is a vertical section on line 6-6, of Fig. 5. Fig. 7 represents a top view of Fig. 5. Fig. 8 is anend view of the same. Fig. 9 shows one of the guide rods for the vertically movable 'bolster-rail, in detail, and illustrates the'manner in which the same is properly lined for its work. Fig.. 10 shows across section of the ringrail, together with the bobbin and bolsterrail in its highest position. Fig. 11 illus- A trates the cam whereby the bolster-rail is l5 raised or lowered so as to give longer or shorter traverse to the spindle rail during the laying-on operation, and, consequently,

giving the desired shape to the lower end of the built-up bobbin. Fig. 12 is a view corresponding to Fig. 10 but shows the spindle and bolster-rail in a lower position. Fig. 13

is a view similar to Fig; 11, showing the position of the cam which the latter occupies to correspond to the position of the holster-rail shown in Fig. 12, and Fig. 14 is a diagram illustrating the connections between the coperative elements.

In general practice ring-spinning frames comprise a pair of rows of spindles disposed at opposite sides of a frame which supports near the center thereof a longitudinally disposed cylinder which is generally made out of tin and from which hands run over the spindle-whirls. As a rule, each spindle of the series has its own driving band, while in the present instance the mechanism is such that the same band )perates one or more spindles on each side of the machine. Furthermore, in machines of this kind as ordinarily constructed, the spindle-supporting or bolster-rail is normally stationary, while the ring-rail is moved vertically relatively thereto so as to lay the yarn on the bobbin. In contradis tinction to this construction the machine here illustrated comprises a frame in which the conditions are reversed inasmuch as now the ring-rail is normally stationary, while the bolster-rail with its spindles is moved vertically relatively to the ring-rail.

Referring now to the drawings, the numeral 20 denotes a pair of end frames which are connected by ties in the usual manner and which support near the top thereof roving ,rolls 21 of the usual construction and operation.

From the roving rolls 21 the yarn is guided to twisting mechanism or twisterheads indicated in a general way by 22 from which the yarn is conducted to delivery rolls 23 which may also be of usual.

construction.

Disposed verticallybeneath the delivery rolls 23 are the usual thread guides and the spindles upon which the yarn is tov be wound. These :spindles are herein designated by s s and the whirls lw, fw (see Fig. lt) which are connected and driven by a band b passing from the whirl 'w thence over an idle pulley z', thence over the driving cylinder d, thence over the whirl fw of the spindle s and thence back to the whirl fw. The idle pulley i is journaled in bearings on an arm 24 which is pivoted on a 'shaft 25 extending between brackets 26,

each arm 24 having a rearward extension 24 adapted to receive a weight 27 whereby proper tension may be applied to the band and which also permits vertical movement of the driving band with the spindles, while the driving cylinder d remains stationary so that in this manner the vidler performs the double function of a band-tightener as well as a take-up for the same.

Extending between the end-frames 20, are a pair of ring-rails 30 which are stationary and secured to said end-frames in any desired manner. Each ring-rail is provided with a number of ring-sockets 31 (see Fig. 10), the anges 32 of which are adapted to guide the travelers 33 through which the yarn passes preparatory to its being laid on the bobbin B which may be of universal construction and placed upon the spindle s.

The lower end of each spindle s is stepped into a bearing or bolster 34, all of which bolsters are supported in the bolster-rail 35 which, as above stated, isin the present instance adapted to be moved vertically so as to move the spindle, and thebobbin mounted thereon, vertically through the ringrail 30.

While, as above described, the ring-rails 30 extend between the end-frames 20 of the machine, the bolster-rails 35 are comparatively short in length and comprise alined sections each of which carries a certain number of spindles, it being understood, however, that each bolster rail section (comprising the two opposite rail-portions thereof) will be moved simultaneously. In order to provide proper guiding means for the bolster-rails, a support-rail 36 is provided extending from end to end of the machine and suitably supported in the end-frames 20 (see Fig. 1). Extending upward from the support-rail 36 are a series of guide-rods 37, preferably four in number for each spindle-s'ection, and having their upper ends secured in the stationary ring-rail 30 which also extends from end to end of the machine. In order to bring these rods. 37 into perfect parallelism with each other so as to guide the bolster-rail properly, the lower support-rail 36 (see Fig. 9) is provided with apertures 38, the diameter of which is larger than that of the rod 37, so that as a matter of fact, the lower end of the guide-rods 37 has suiiicient freedom to be moved about vuntil perfect parallelism between the rods is obtained. The lower ends of these rods are then rigidly secured in position b v means of brackets 39 within which the rod 37 may be clamped, as for instance by a set screw 40, while the bracket 39 itself may be rigidly secured lto the support-rail 3G by bolts such as 41a (see also Fig. 1).

From the above, it will be understood that each spindle-section may be guided on four rigid rods. The particular manner of operatively connecting the opposed bolster rails and for guiding the same on the guiderods 37 is clearly shown in Fig. 9, in which is shown the end of a yoke 41 which extends from side to side of the machine, and surrounds with its ends the rods 37. At these points the yoke 41 is provided with a thimble 42 having its upper end flanged as at 43 and bored so as to have a sliding fit on the rod 37. The flange 43 rests upon the top of the bolster-rail 35 and the latter, together with the yoke, are firmly drawn together by means of a clamp-nut 44 applied to the thimble 42. Each yoke 41 preferably consists of cast iron end-pieces which are united by a Stringer 41 and the two yokes which support each spindle-section are raised and lowered by mechanism as follows: Refer-- ring to Figs. l, 2 and 3, it will be noted that tie-rails 45 connect the two end frames 20, and on these tie-'rails are supported brackets 46 which in turn support carrier-rails 47 on which are held a series of studs 48 upon which a series of pulleys 49 are mounted for rotation. These pulleys 49 are arranged in pairs to receive a band or chain 50 which by one end are secured to the yokes 41, are intermediately connected to the tie or equalizing rod 53, and which carry at their other ends counterweights 52 of sufficient capacity to nearly counterbalance the weight of the yokes and bolster-rails carried thereby, this weight, however, being such that when no pull is exerted on the band'50 other than that of the counterweight 52, said yokes and parts carried thereby will gravitate. In other Words, in order to raise the yokes, a pull must be exerted upon the band, such pull being exerted upon all the d'it'i'erent bands simultaneously by a single member on each side of the frame which may be con nected with, or disconnected from, the several bands 50.

By referring to Fig. 1 it will be seen that an actuator 53 is disposed above the horizontal section of the several bands 50, and means are provided whereby the member 53 may be readily attached to, or disconnected from, the bands 50, so that in this manner any one of the bolster-rail-sections may remain stationary, while the other bands pertaining to other spindle-sections may be operated without interference. Attached to the end of the member 53 is a flexible band 55 passing over a pulley 56 which is journaled on a stud 57 also held in the rail 47. The lower end of the flexible band 55 is attached to theperiphery of a cam 58 (see- Figs. 1l and 13) mounted upon a shaft 59 which may be suitably journaled on the rail 45 of the machine. The cams 58, chains 55, and chain guiding pulleys are duplicated as manifest for a balanced action of the devices. Also mounted upon the shaft 59 is a drum 60 whereby rotation is imparted to the shaft 59, as for instance by a band or chain 61, the upper end of which is secured to the drum 60, while its lower end is connected with a traverse and buildingup mechanism which latter is clearly illustrated in Figs. 5, G, 7 and 8. The lower end Vof the chain 61 is attached in an indirect manner to the traverse mechanism which comprises a vertically oscillatory bar 65 (see' Fig. 3) pivoted at 6G to the frame of the machine and carrying at its free end the building-up mechanism to which reference will be had hereinafter. Leaving this mechanism ont of consideration for the present and considering for a moment that the chain 6l were permanently attached to the free end of the bar 65,the means whereby the latter is oscillated would produce simply an up and down movement to the chain 61, so

that `consequently, the bolster-rail would be ent instance of a cam 67 (see Fig. 5) secured upon a shaft 68 (see also Figs. l and 2) which is journaled in suitable brackets 69 and 70, supported in any appropriate manner. The shaft 68 carries a bevel gear 71v in mesh with a bevel pinion 72 on a shaft 73 which is journaled in bearings 74, 75, secured to the frame. The shaft 73 is provided at its upper end with a worm-gear 7 6 engaged by a worm 77 on a horizontally disposed shaft 78 which has driving connection with the drawing rolls in the usual manner. The cam 67 engages a roller 81 (see Fig. 5) journaled on a stud 82 which is secured to the arm 65 above referred to. Now, it will be seen that the weight of the several yokes will cause an upward pull on the chain 6l, so that consequently the roller 8l will be maintained in contact with the cam 67 so that the rotation of this cam will produce a vertically oscillatory movement of the arm 65, and, therefore, substantially raise the bolstenrail 35, while the latter will gravitate again as soon as the return por tion of the cam 67 comes into coperation with the roller 81. The amount of movement which is given to the bolster-rail by the cam 67 produces the traverse or layon of the yarn on the bobbins which latter are in the present instance intended to receive the filling f or the loom shuttles; or in other words, the yarn is laid onto the bobbins for a dist-ance of approximately one and one-half inches ot its length and consecutive layers are laid on in successive zones until the entire bobbin is filled.

Means are provided whereby the zone of movement of the bobbins relatively to the ring-rail will be varied to produce the result just now mentioned, and in the present instance, I preferably attach these means to the free end of the arm 65 in such amanner that at each `full reciprocation of this arm, the chain 61 will. be unwound for an amount equal to the dierence between the starting points of the several layers of the bobbins. This result is achieved as follows: The lower end of the chain 61 is attached as at 83 Fig. 6, to a drum 84 keyed on a shaft 85 which is journaled inY bearings 86 on a bifurcated bracket 87 which may be secured to the end of the builder-arm 65. The shaft 85 has, furthermore, secured thereto a worm-gear 88 in engagement with Aa worm 89 mounted on a shaft 90 which is also journaled in bearings of the bracket 87 and which carries at its outer end a ratchetwheel 91 whereby a step by step movement is imparted to said shaft, as for instancel by a pawl 92 pivoted on an abutment-arm or pawl carrier 93 which is fulcrumed on the shaft 90 at a point intermediate the ratchet-wheel 91 and the bracket 87 and the downward movement of which is limited and controlled by an adjusting screw 94 in screw threaded engagement with an ear 95 projecting from the bracket 87. The free end of the arm 93 is so located that during the descent of the builder-arm 65, it will come into contact with an abutmentepin 96 which is vertically adjustable in a slot 97 provided in a bracket 98 supported on the supporting-rail 36 above mentioned (see Fig. 1). When it is now considered that the amount of oscillatory movement of the builder-arm 65 is always the same and as controlledby the cam 67, it will be understood vthat by varying the position of the abutment-pin 96 and also by proper adjustment of the screw 94C, the mechanism in its entirety may be changed so as to produce a feed movement Aof the ratchet-wheel from nothing up to tive or six teeth thereof, so that consequently every time when the arm 65 descends, the ratchet-wheel will be partially rotated, which movement will result .incorrespondingly moving the drum 84 and thus unwind the chain 61 for a proportionate amount. This means in other words, while the actual amount of movement of the bolster-rail will remain the same for each oscillation of the builder-arm 65, the location or zone of such movement depends entirely upon the position of the drum 84 which, as above stated, varies constantly and progressively until it has reached its limit of movement and the bobbin is full.

Mention has above been made of the provision of a cam 58 and its actuating-drum 60, both of which are secured upon the shaft 59. The organization being such that while the lower chain 61 is attached to the drum and will, therefore, rotate the shat 59 evenly with the rotating movement of the drum 84, yet the movement ofthe pull-chain 5() is variable as controlled by the cam 58 a. portion of the periphery of which is disposed at dierent distances hom the center. The particular purpose of this organization is to enable me to vary the formation or building-up of the yarn on the lower" end of the bobbin. It' being evident that the number of rotations of the spindle remaining constant, the thread to be wound onto the bobbin, or in other words, its buildingup will be controlled entirely by the rapidity of movement with which the naverse takes place. In other words, the shorter the traverse movement. more thread will be wound onto a certain bobbin-space and the duration of the traverse being always the same, and vice versa, the longer the traverse movement is, the less yarn will be woundron the bobbin in the same space in the same time.

By referring to Figs. 10 to 13 inclusive, it will be noted that in Fig. 10 the yarn is wound onto the bobbin at the bottom thereof, the bolster-rail being in its highest position so that the cam 58 in its movement in direction of arrow a Fig. 11 will permit the bolster-rail to descend at a gradually increasing rate, as for instance between the lines I; and c (see Fig. 11) after which the cam is concentric and the movement is uniform. The result of this cam movement is the building-up *of` the bobbin as indicated by m in Fig. 10 to correspond with the movement ofthe cam between lines b and c while m corresponds to the laying-on ofthe yarn during the rest of the travel of the cam 5,8, that is while its concentric part has coaction with the pull chain. By means of varying this movement I am enabled to form a full round bottom on the bobbin in any desired marmer, as shown in Fig. 12, and without in any way interfering with the movement of the traverse.

The let-out cam is so shaped that the first portion b-c of its chain-unreeling movement will allow the bolster rail to drop for a distance m smaller than the actual travel of the chain-end e ailixed to the cam, and so that the remaining portion c-e of itschainunreeling movement will drop the bolster -rail evenly and for an amount equal to the travel of the chain with the cam. in other words: while the cam 58 is yrotated at an even speed, the chain is unreeled from a peripherally reduced portion so as to allow the` bolster rail to drop a shorter distance within the given period until a certain point c has been reached, and then the let 0E is uniformly at the attained higher speed and in longer extent during the rest of the cam rotation vwhile the chain is unreeled from the concentric portion of the cam.

The particular manner of operating or 'driving the main cylinder of the machine which, as above stated, operates the spindles disposed on opposite sides of the floor, respectively, is immaterial in the present case, it being understood that said cylinder is driven from the main shaft in the usual manner, which main shaft is also connected with the driving shaft 78, so that the spindle speed and the traverse movement will remain at the same ratio throughout the operation of the machine.

Many changes may be made in the organization and construction of the several elements `of which my improved machine is composed, without departing from the spirit of the invention.
