To all whom t may concern:

Be it known that I, J oHN LOWE, a subject of the King of Great Britain, and a resident of New Bedford, in the county of Bristol and State of Massachusetts, have invented an Improvement in Spinning-Mules, .of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to spinning mules, and in the embodiment herein selected for purposes of illustration, in order that the principle f the invention may readily be understood, it is an improvement upon the 4United States Patent to Henry S. Golland,

No. 873,422, December 10, 1907.Y

In the drawings ,-Figure 1 is a view, partially in side elevation and partially in section, of a portion of a spinning mule having my invention applied thereto; Fig. 2 is a front AView with parts removed, of a portion of the mechanism shown in Fig. l; Fig. 3 is a detail representing in side elevation a portion of the mechanism for operating the parts shown ink Fig. 1; Fig. 4 is a front elevation of the construction shown in Fig. l; Fig. 5l is a vertical sectional-view taken upon the broken line 5-5 of Fig. 4; Fig. 6 is a view partially in side elevation and partially in vertical section of a portion of my invention; Figs. 7 and 8 are views in side and end elevation of the preferred form of means for placing the faller locking lever in operative engagement with the copping rail; Fig. 9 is a view partially in side elevation and partially in vertical section and showing the preferred mechanism for operating the faller; Fig. l() is a diagram illustrating the movements of the cross wind guide and the faller to produce the cross wind formation of the cops; and Fig. 11 is a view mainly in side elevation showing the preferred form of spindle driving mechanism.

The patent to Golland, No. 873,422, discloses a spinning mule in which the yarns are vibrated as the mule carriage runs in, by means of a guide rod or wire placed between the winding spindles and the winding faller wire, thereby to lay the yarns in cross Wind- 'in'gs To this end, the cross wind wire had imparted thereto a number of vibrations during each winding run 'of the carriage.. The faller Wire, however, was held stationary during each wmdmg run and received only such very slight forward movement as was necessary to build the cops, such movement being synchronous with the gradual elevation of the cross wind wire. I have ascertained by practical tests that a cop wound in the manner described in ksaid patent is not of uniform hardness throughout, this defect being due to the factv that the cross wind wire docs not control the tension of the yarns but permits the formation of slack, particularly when said cross wind wire moves downward or toward the faller wire which, as previously stated, is stationary at this time, and therefore cannot apply proper tension to the yarns.

In order to overcome the defects to which I have referred I provide means to prevent the formation of slack during the cross winding movements of the cross wind guide and preferably accomplish this result by imparting to the faller wire a plurality of movements during a single winding run of the mule carriage corresponding in number to the cross wind movements of the cross wind guide, these movements of the guide and yfaller wire occurring substantially simultaneously but preferably differentiated in extent for purposes hereinafter described. It is apparent, however, that the said movements of the cross wind guide and faller wire need not be differentiated' but may be the same both in time of occurrence and in eX- tent.

The cross wind guide employed by me is preferably operated by the .same general mechanism disclosed in said patent and constitutes the cop building mechanism. The faller to which I impart the movements heretofore referred to as conforming substantially to the movements of the cross wind guide, is employed by me not as a cop building mechanism but as a tensioning and yarn direct-ing mechanism. In order to irnpart said movements to the faller, preferably I employ a copping rail presenting certain novel characteristics to be hereinafter Mmore particularly set forth.

Referring more particularly to the drawings, the mule carriage is represented at 1, it having mounted thereon the usual spinning spindles 2 driven in suitable manner. At each side of the head stock the mule carriage 1 is provided with a rock shaft or rod 3 rotatably mounted in bearings 4 provided by pokers 5 which are slidable in brackets 6 secured to the front of the mule carriage 1. At proper intervals along the length of the rock shafts 3 are carried bent Vfingers 7 through one en d of which pass the cross wind guide or guides 8, preferably intermediate the spindles 2 and the faller wire 9 shown in Fig. 9.

-In order to rock the shaft 3 carrying the cross wind guide 8 at each side of the head stock, I may provide any suitable mechanism but have herein shown in Fig. 4 a rack 10 fixed to the floor, and secure a bracket 11 to the front of the mule carriage 1 at the end near the head stock, said bracket providing bearings for a shaft 12 carrying a pinion 13 shown in dotted lines in Fig. 4 and meshing with the rack 10. The pinion 13 is here shown as carrying a beveled Wheel 14 meshing with a beveled wheel 15, shown in Fig. 5 as formed upon a sleeve 16 rotatable in bearings in the bracket 11. Preferably the bracket is of such construction as to inclose the pinion 13 and beveled wheels 14 and 15. The sleeve 1G is here shown as inclined to the vertical corresponding to the angle of inclination of the spinning spindles 2, and slidable within `the sleeve 16 but rotatable therewith by means of a slip feather and groove, as indicated in Fig. 5, is a shaft 17, the upper end whereof is loosely socketed in a cross head 18 shown in Figs. 1, 4 and 5. The said cross head 18 is loosely connected to links 19 which are also secured to an adjustable crank 20 shown in Fig. 1 as connected to the rock shaft 3 to rock the same, and thereby to impart to and fro cross wind movements to the cross wind guide 8.

' To enable the shaft 3 to be rocked through the medium of the crank 20, links 19 and connecting shaft 17, the said shaft 17 is reciprocated within the sleeve 1G, in addition to partaking of the described rotary movement of said sleeve. This reciprocatory movement should be the shortest when first commencing to wind upon the bare spindles, so that the throw of the cross wind guide 8 will alsobe short, in order to form a thick or blunt bottom. The throw or traverse of the said cross. wind guide 8 should be automatically and gradually increased during the formation of the cop bottom, the maximum traverse of the said guide being attained when the cop bottom is completed. After the cop bottom has been formed the maximum traverse of the said cross wind guide is maintained throughout the entire building of the cops. In order to effect this result, I have in the selected embodiment of my invention providedy the shaft 17 with a boss 21 shown most clearly in Fig. 5 and provided with two cam grooves 22 and 23. Inelosed within a casing 24, herein forming a bearing for the shaft 17 are two plates 25 and 26 shown also in Fig. 2, in which ligure the front of the casing 24 has been removed. The plates 25 and 26 are provided respectively' with bowls 27 and 28 rotatable on studs 29 secured to the said plates 25 and 2G. The cam groove 23 is of less pitch than the cam groove 22. If therefore'the plate 25 carrying the bowl 27 be held fixed while the plate 26 is allowed to rise and fall freely in the casing 24, the shaft 17 when rotated in the manner described will also be reciprocated within and relative to the sleeve 1G to its minimum extent, owing to the influence of the bowl 27 upon the cam 23. If the said fixed plate 25 bey gradually released so as to allow it to rise and fall within the casing 24 to an increasing extent and also at the same time the loose plate 2G be gradually locked within the easing to prevent its rising vand falling, the influence of the bowl 27 upon the cam 23 will be diminished while the efect of the bowl 28 upon the cam 22 will be correspondingly increased. As the bowl 28 engages with the cam 22 having the larger throw or pitch, the result is that the shaft 17 is gradually reciprocated to an increased extent until the cop bottom is finished, when the plate 25 is entirely released. The plate 2G is at that time locked so that the bowl 28 being substantially immovable, its influence upon the cam 22 of greatest pitch causes the shaft 17 to receive its greatest reciprocatory movement within the sleeve 1G, and thereby to vibrate the cross wind guide 8 through an arc of a circle to its maximum extent, as indicated in dotted lines in Fig. 1. To effect the locking and releasing of the plates 25 and 2G, they are each loosely pivoted by pins 30, 31 to slide plates 32, 33, shown most clearly in Figs. ,K2 and 5. said plates being provided with slots 34. W'ithin the slots 34 are positioned pins 35, carried by a boss 36 on a bar 37, here shown in Fig. 2 as slidable in a straight line within the casing 24. In the position shown in Fig. 2, the pins 35 come below the pin 31 which loosely pivots the plate 33 to the plate 2G, and said plate 2G is thereby' locked or held stationary. The plate 25 is free or capable of oscillating within the casing 24, but if the bar 37 be moved to the left viewing Fig. 2, to bring the pin 35 immediately below the pin 30, which pivots tbe plate 32 to the plate 25, the said plate 26 is thereby gradually released and the plate 25 is gradu-` ally locked, This movement of the bar 37 is preferably accomplished by a lever 38 having a slotted end 39, shown most clearly in Fig. 1, engaged with the pin 35 upon4 to be hereinafter described to direct the tion opposite thatv shown in Fig. 2.

Fig. 4, so that when the pin 42 of the lever 38 is engaged therewith the pin 35 is positioned beneath the pin 30, or in the poiy mechanism to be described, the casing 24is gradually elevated during the building of -the cops and the pin 42 upon the lever 38 is thereby moved into the vertical portion of the cam way 43, thus moving the lever 38 to the right as indicated in Fig. 2, thereby to position the pin 35 beneath the pin 3l and to lock the plate 26 into position. During the running out of the mule carriage in the operation of spinning. the yarns are delivered by the rolls in the usual manner. The yarns are then directed from the eX- treme tips of the spinningspindles 2 as is well known, and in this position the yarns are out of reach of the cross wind guide 8 which, although vibrating, cannot touch the yarns and is thus inoperative. The counterfaller shaft is indicated at 45 in the several ligures, the taller shaft being indicated at 4G, and the taller at 47 and carrying the faller wire 9. When the mule carriage runs in to wind the yarns on the spindles, the faller wire 9 is depressed by mechanism yarns to the bases of the cop noses. as indicated in Fig. 9, and the cross wind guide 8 ismoved to and fro longitudinally of the spindles a plurality of times during each winding run of the carriage, thereby to raise and lower the varns between the bases and apices of the cop noses. and thus to lay yarns upon the spindles in a cross wind.

In order to build the cops a coppingmotion is provided synchr mm|sly to raise the cross wind guide 3 and the taller wire 9 to the required slight degree each time the mule carriage runs in. For this purpose l have herein disclosed the following mechanism: rl`he shaft l2 carrying the pinion 13 meshing with the rack 10 upon the floor carries also as shown in Fig. 3 a disk 48 having a pivoted pawl 49 which is inoperative on the run out of the carriage, but which when the carriage runs in and the yarns are being wound upon the spindles comes into contact with and actuates a lever 50 carrying the pawl 51' which intermittently rotates a ratchet wheel 52 fixed upon a shaft 53 carried in suitable bearings in the frame of the mule carriage. The ratchet wheel 52 is locked by a d etent 54 shown in Fig. l. and the motion of the shaft 53, shown also in dotted line in Fig. 9, is communicated by a worm 55 indicated in dotted lines in said figure, to a worm Wheel 56 fixed on a vertical screw shaft 57 mounted in suitable bearings and having a worm 58 gearing with the worm wheel 59 on the shaft 60 mounted in suitable bearings in the mule carriage. The shaft G0 thus slowly rotated is provided with a pinion 6l shown in Fig. 1, which meshes with a rack 62 secured to the casing 24 so as gradually to raise the said casing and the vertical shaft 17 therewith as the cops are being formed, the casing having suitable guiding brackets permitting said sliding movement. The shaft GO, as shown in Fig. G, is also provided with a suitable number of pinions 63 meshing with racks 64 secured to the pokers 5 oarrying the rock shaft 3, as already stated. ln this manner, as vthe carriage runs in the cross wind guide 8, in addition to being oscillated through the arc of a circle as described, also is raised the slightdegree necessary to build the cops by the lifting of the pokers 5 and the casing 24, also actin@ as a oker. D

The taller wire 9 is not held stationary during the running in of the carriage, as disclosed in said Golland patent, but has imparted thereto during each winding run of the carriage a plurality of cross Wind tensioning movements equal in number to the cross wind movements imparted to the guide 8. lnasmuch as the cross wind guide 8 lays the yarns upon the cops, the taller wire 9 is employed to tension the yarns so as to prevent the formation of slack particularly at that point in the layin of the cross wind when the cross wind gulde, having been elevated repeatedly during each winding run of the carriage, is about to descend. Inasmuch as the taller wire in the Golland patent was held stationary during these repeated rising and falling movements of the cross wind guide, when the said guide began each downward movement the yarn became slack as the guide was withdrawn from beneath them, and the taller wire being stationary could not take up the slack nor maintain the tension. The counterfaller wire, which in the Golland patent was of the usual type, did not maintain this tension.

In Fig. 10, I have illustrated diagrammatically the movements imparted to the cross wind guide and to the taller during-a single winding run of the carriage. ln said ligure, the extreme upward position assumed by the cross wind guide 8 during a single winding run is represented. at 8a, there being,

iu this embodiment of my invention, four to and fro cross wind movements imparted to the said guide during each winding run of the carriage. The extreme downward position assumed by the said cross wind guide during each winding run is indicated at 8b. Similarly the extreme upper and extreme lowermost positions of the taller wire are indicated at 9 and 9b respectively,l it being evident that for each to and fro movement iniparted to the cross wind guide 8 a corresponding to and fro movement is imparted to the taller Wire 9. lVithin the scope of my invention, the movements imparted to the cross wind guide and to the faller wire may be identical both in time of occurrence and in extent of movement, but preferabl and as here shown they are somewhat di fcrentiated in order -to impart a slightly greater tension to 'the'yarns as they are laid upon the noses of the cops, or in other words, when the yarn is being wound upon the portion of the cop that is of the least diameter. In order to laccomplish this result, I have, in this embodiment of the invention, terminated the upward movement of the faller wire 9 prior to the termination of the corresponding upward movement of the cross wind guide 8, with the result that the continued upward movementof the cross wind guide imparts a slightly greater degree of tension to the yarn as it is laid upon the noses of the cops. Either simultaneously with or slightly after the commencement of the downward movement of the cross wind guide 8, according to which form of my invention may be employed, the faller guide 9 commences to move downward, thereby maintaining the proper tension upon the yarns and preventing the formation of slack, and thus absolutely controlling the angle of delivery of the yarns past Said cross wind guide to the cops. It will be evident that were the faller wire not moved in the manner indicated, that the angle of delivery of the yarns past the cross wind guide 8 would not be maintained when the guide is moved from beneath it.

Although I have described the tensioning of the yarns as accomplished during the cross winding movements of the guide 8 by the corresponding movements of the faller wire 9, this tensioning may be accomplished in any other suitable manner.

In order to effect the described movement of the faller, I have herein provided a copping rail 65 shown inFig. 9, the upper edge 66 thereof being in a horizontal plane and not generally inclined from front to rear, as customarily used in the formation of cops not of the cross wound character. At front and rear the copping rail is provided with lateral pins 67 riding upon inclined shoes 68 of equal slope, the said shoes beingpgradually moved longitudinally in the customary manner by screw shaft 69 engaging nut 70 upon one shoe 68 and having a ratchet 71, the pawl'72 whereof is shifted by a cam 73 upon the carriage of the mule at each winding run. The shoes 68 are connected by slide rod 74, so as to move in unison and to move the shoes 68 equally, thereby to but is employed merel to give tension to the yarns through the taller wire. 4

The faller shaft 46 is provided with the usual locking lever 75 provided at its lower end with a block 7 G adapted to be positioned during each winding run upon a bowl 77 mounted upon the upper end of a bracket 78 mounted for sliding movement in suitable guides in the mule carriage. The lower end of said bracket 78 is provided with a bowl 79`adapted to rideupon the upper edge of the copping rail 65. The locking lever 75 is provided with a monkey tail 80 adapted to be struck by a projection 81 at the end of the winding run to knock the block 76 from the bowl 77, and thereby to render the faller wire 9 inoperative during the outward run of the mule carriage.

Any ordinary means may be employed to elevate the locking lever 75 and thereby to depress the faller rail 9 at the commencement of each winding runof the carriage. For this purpose, I have in Figs. 7 and 8 represented the shaft as provided with a pinion 82 meshing with a gear 83 carried by a suitable bracket 84 and having co axial therewith a pinion 85 meshing with a rack 86 suitably guided in the bracket 84 and carrying a bowl 87 positioned beneath a shoulder 88 of an arm 89 keyed upon the faller shaft 46, thus rotating said faller shaft and elevating the block 76 of the locking lever 75 to a suitable raising to be received upon the bowl 77. The arm 89 projects downwardly into engagement with a bracket 90 upon the Hoor to guide the parts during the operation of elevating the locking lever 75 and permitting the block 76 to be moved inwardly upon the bowl 77 at the proper time.

In order to impart the described plurality of to and fro movements to the faller wire 9 during each winding run of the carriage, I provide the upper Surface of the copping rail with a series of swells 91 corres onding in number tothe number of to an fro cross windin movements imparted to the cross win each winding run of the carriage, in this instance four being shown. Each of the said swells is represented as a bracket secured to the copping rail, though if desired it may be formed integral therewith. Preferably and as indicated the copping rail is provided with a slight dwell or level part 92 between adjacent swells 91, these dwells permitting the differential movements of the cross wind guide 8 and faller wire 9.

It will, however, be understood that the swells 91 may be merged into each other, so that the movement of the faller wire is substantially continuous, and thereby may be wholly synchronous with the movement of the cross wind guide 8.

I provide means to arrest momentarily guide 8 during the upward movement of the faller wire 9. When it is opposite the apices of the cop noses to take up the yarn at this point as customary. This result I accomplish by providing the inwardV or right hand end of the copping rail with a downward ineline 93 below the level of the upper edge of said rail and merging into a level portion 94, onto which the bowl 7 9 rides, thereby maintaining the faller wire 9 momentarily arrested opposite the apices of the cop noses,l as indicated at 9c in Fig. 10. If desired, the incline 93 may be a continuation of the terminal swell 91. In this manner, I prevent the formation of slack yarn.c that would otherwise occur aty this point, and thus effect in part at least the function heretofore accomplished by driving the spindles at a faster speed during the nosing action.

In spinning mule cops not. of the cross wound type, each yarn iswound upon its cop by a succession of close and substantially contacting turns or spirals from base to apex of each conical layer, the yarn being returned from the apex to the base by a series of open turns of much smaller number. For exam ple, in spinning mules not of the cross wound type, there are customarily about twenty turns of yarn iny winding from base to apex and six turns from apex to base, the spindles 4'rotating more slowly during the twenty upward turns, although there is a constant acceleration. In the cross wound type of cop formed by the mule herein disclosed there` are fourupward and four (,lownward movements of the cross wind guide and the faller, and during each up and' each of the down movements, the mule as herein organized lays six turns of the yarn upon the cop. It may therefore be desirable to impart a more nearly uniform cr eien spindle speed during the said four upward winds and the said four downward winds, as said winds are not differentiated from each other as in the former type of cops. This result may be Aaccomplished in any suitable manner, as, for example, by so controlling the quadrant as to impart a minimum oscillation thereto through the usual gear meshing with the rack of thel quadrant. l. have. however, in Fig. 11 illustrated another form of mechanism similar generally to that heretofore used in twiners and by which the indicated result may be secured.` In said figure. I have represented a quadrant motion wherein the winding chain or band 95 passing to the nut 96 of the screw shaft 97 carried by the quadrant 98 is passed about a guide 99 carried by the framing of the head stock, the said winding chain or band passing first about the guide 10() upon the nut` thence about the guide 99, and then again to the nut where the end of it is secured as indicated at 101. In quadrants as heretofore constructed and adapted to Wind cops not of the cross Wind type, the quadrant moves in an extended arc and when at the downwaljd limit of its movement extends substantially horizontally, thus compelling greater movement of the Winding chain, because the quadrant itself gives off less chain. By the described construction, I am enabled to move the quadrant through a. much less are, approximating substantially one third o-f that heretofore made necessary and move the nut 9G to a much less extent than heretofore, thereby compelling a more uniform or even spindle speed during the run in of the mule'carriage. The winding chain or band 95 has its end opposite that secured upon the nut 9G wound upon a drum 109J which may be and preferably is of substantially uniform diameter throughout the greater portion of its length, but which at one end is provided with a scroll tapering from the diameter indicated to the shaft whereon the drum is mounted. During each winding run of the carriage and at or about the termination o f such winding runs the band or chain is received upon such tapering scroll portion of the drum, thereby to speed the spindles up and thus take care of the extra yarn during the nosing action. Such scroll may be used in lieu of the nosing arm of the quadrant commonly employed to bear upon the chain and increase the spindle speed.

From the foregoing description, it will be apparent that by imparting to the faller wire a series of movements during each winding run of the mule corresponding to and either synchronous with or differentiated from the cross wind movements of the guide S, the tension of the yarns is controlled and the angle of delivery of the yarns past said cross wind guide is controlled at all times. while at the same time by differentiating the movements of the faller and the cross wind guide I secure the effect of the nosing action by imparting increased tension to the yarns as the latter are being wound upon or closely adjacent the apices of the cop noses. By employing a preferably common or con- Iioint mechanism for imparting the cop building movements to the cross wind wire and to the faller Wire and by employing independent means to impart the cross wind nimYements to the guide 8 and to the faller wire 9, I am enabled absolutely to control the varns during suoli cross Winding movements and to differentiate the said cross winding movements of the guide 8 and faller wire 9 as may be desired. By employing a copping rail to impart the cross wind tensioning movements to the faller wire, I greatly simplify the construction of parts.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in ageneric and descriptive sense and not for purposes of li1nitation, the scope of the invention being set orth in the following claims.
