TRAVERSE-MOTION FOR YARN-SPINNING APPARATUS.

Specification of Letters Patent.

Patented Nov. 30, 1909.

Application filed February 13, 1909. Serial No. 477,532.

To all whom it may concern: I

Be it known that I, ALoNzo E. RiioAoEs, a

citizen of the United States, and resident of llopedale, county of Worcester, State of Massachusetts, have invented an Improvemerit in 'lraverse-Motions for Yarn-Spin- 'ning Apparatus, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing l ke parts.

This invention relates to apparatus for spinning yarn, and it has for its object thetion is of very simple construction, there befing but a single connection between the builder-motion and the usual rocker through ,which the vertical movement of the ring-rail is controlled. I

The construction and operation of the builder-motion herein are such that the yarn I .is laid at the beginning of the winding with g the minimum traverse, and such traverse increases automatically and gradually through V 'out the winding operation, but in order to give the proper and desired conformation to the yarn mass on the receiver or bobbin the gain starts at the maximum and gradually dccrcases throughout the winding.

V l t is well known to those skilled in the art .tlnitithe same quantity of yarn is laid at each traverse, hence a shorter traverse lays the yarn much more closely than a longer traverse does, so that. at the beginning of the winding, when the traverse is short, there is atendency in the yarn laid on one traverse to roll over the yarn laid .on the previous traverse, particularly at the lower end of the ,traverse, so that there is more or less interi ference between the two portions of the, yarn, causing it to draw ofi' improperly and unevenly in the shuttle.

With a gradually increasing traverse the increment of increase on successive strokes of the ring-rail is sosmall that such rolling over or crowding of the yarn cannot be obviatcd by the traverse alone, and in my present invention l overcome the obj cction noted by starting the winding with a maximum gain. By so doing I carry the ends of successive layers of yarn far enough to extend beyond those immediately preceding, and thereby lay each layer properly and evenly upon the yarn-receiver, without any rolling over or crowding of the turns of one layer into the. turns of the layer beneath, and

.the yarn in consequence draws ofl' evenly and without obstruction, in the shuttle, down to the very beginning of the winding if need be. The completed yarn-mass tapers gradually up to the body portion, at its lower end, and tapers gradually in the opposite direction at the top of the body-portion, obviating the formation of a pear-shaped yarn-mass, which shape, is highly objectionable. \Vhile the maximum gain at the be ginning of the winding obviates the fault referred to it is necessary to effect a gradual decrease of the gain during the winding, and

I have made provision therefor, as will appear hereinafter. Vere it not for such gradual decrease of the gain the structure embodying my invention would so. operate that the winding would be completedwith relatively a very small quantity of yarn laid.

The various novel features of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure l is a front elevation of a sufficient;

portion of a spinning-frame with one prac-' .tical embodiment of my invention applied thereto, the ring-rail being shown somewln t above its lowest point, but otherwise tl e mechanism is in readiness to begin the windmg of a set of bobbms; Fig. 2 1s a transverse section on the line 22, Fig. 1, looking toward the left, showingthe builderanotion and the actuating cam therefor in side elevation; Fig. 3 is an enlarged detail, partly broken out, of the builder-arm and parts carried thereby, but with the winding-drum and its gear removed; Fig. 4 is a transverse section on the line 44, Fig. 3, looking toward the right, but with the winding-drum and its gear in place; Fi 5 is a similar view on the line 5-5, also looking toward the right; Fig. 6 is a left-hand elevation of the builderarm, showing the ratchet by means of which the traverse is varied, and the shield to gov- In the present'embodiment of my invention the ring-rail is raised by a suitable lifting-weight and depressed by or through the builder-motion, the winding mechanism letting off the chain from the winding drum or barrel to govern the gain of the traverse, while the traverse itselfis gradually increasedby a gradual bodily movement of the drum from the fulcrum of the builderarm.

Referring to Fi s. 1 and 2, the spindle-rail 1, rotatable spind es 2, the vertically-reciprocating ring-rail 3 provided with usual rings 4, the lifter-rods 5 (one being shown in Fig. 1) the rocker 6 cooperating with the foot of the lifter-rod and provided with a weight 7 to elevate the ring-raiL-and the rocker-arm 8 rigidly attached to the rocker and transmitting reciprocating movement to the other lifter-rods through the link 9, may

be and are all substantially of well known or usualconstruction in splnning or similar apparatus.

flexible connection, preferably a chain 1Q, as herein shown, iscOnne'cted at one end tothe branch 11 of the rocker 6 and is led over a guide-sheave 12 mounted in a swinging support fulcrumed at 12 on the mam frame and thence to a winding-drum or bar-- rel 13, and attached thereto, said drum having attached to or forming part of it a concentric gear14, said drum and gear-being rotatably mounted on a laterall extended stud 15.fixed on a traveler 16, to be referred to again, which acts as a traverse-changer.

T e builder-motion herein shown includes a builder-arm 17 fulcrumed at 18 on the main frame and provided with a roller or other stud l9 constituting a follower to cooperate with an actuator, shown as a traverse-cam 20havingthree points, Fig. 2, the weight 21 connected with the builder-arm counter-balancing the weight of the parts thereon and maintaining the follower in engagement with-the cam.

As shown in'Figs. 2, 3 5, the builder-arm for the greater portion of its length isv shaped in cross-section, the u per and lower parallel flanges bein longitu inally grooved at22 to formgui eways for the top and bottom of the traveler or traverse-changer 16, as clearly shown in Fig. 4:, retaining plates 23 maintaining the traveler in osition while permitting movement thereo lon- 'gitudinally of the builder-arm. Manifestly the builder-arm has a constant stroke, hence it follows that the farther awa the traverseshifter 16 is moved from the ulcrum 18 the greater the amplitude of movement of the ring-rail, and vice versa, so that if the winding operation starts with the traverse-changer .rin -rail.

, at its extreme inward position, Figs. 2 and 3,

the minimum traverse will be g ven to the be starting point for the traverse-changer 16 is determined by means of a headed stoppin 24 adapted to be inserted in any one ol a series of holes 25 (see dotted lines Fig. 2-5,) in the top flange of the builder-arm, the lower end of the pin being adapted to engage an abutment 26 on the traverse-changer and thereby limit its movement when windingback is efi'ected.

By placing the stop-pin in one of the holes more to the left, Fig. 3, the starting point of the ring-rail will be raised more or less with relation to the butt or head of the yarnrcceiver or bobbin, to thereby adjust, the beginning of the winding of yarn thereupon, and after the stop-pin has been properly set the starting point of the winding will remain the same as one set of bobbins after another is wound, the treverse-clianger .113 being stopped at the same point upon winding back.

Inasmuch the traverse-elmnger moves outward along the builder-arm througluuit the winding the guide'sheave 12 is pivot ally mounted to avoid any cramping or twisting of the chain 10.

Referring to Fig. 2 it will be seen that the chain 10 leads tangentially from the periphery of the drum Iii-up to the sheave 12, which swings on the stud 12*, and as the traverse-changer moves outward the chain will gradually. ap roach a vertical line intersecting the stu so that as the angle between the chain and such vertical line gradually decreases there will be a slight decrease in the distance between the sheave. l. and the point on the drum at which the chain leaves So, too, as the traverse- I changer continues its outward movement beyond-the vertical line through the stud 12* the distance between the sheave 12 and the. point at which the chain 10 leaves the drum will slightly increase. Hence, during the gradual decrease in such distance there will be a gradual increase in the gain, and thereafter a gradual decrease in the gain the distance referred to increases, but in each case in actual practice such variations in the gain are so small as to be hardly appreciable.

As the gain in the apparatus forming the subject-matter of this application is started at a maximum, and gradually decreased throughout the winding, as will be explained hereinafter, it is only necessary to make the initial maximum gain large enough to compensate for the variations just pointed out, so that the change in the position of the traverse-changer with relation to the stud 12* can in practice be disregarded.

The builder-arni has transverse end- plates 27, 27 secured fixedly to the up )er and lower flanges, which plates provide earings for 'an elongated shaft,28 spirally threaded at 2 9 to pass through and engage a threaded hole 30, Fig. 4, 'in the traverse-changer. so

i upright rod 33 held adjustably that rotation of said shaft will slide said traverse-changer longitudinally along the builder-arm. I At its outer end, beyond the plate 27*, a ratchet 31 is secured to the shaft 28, the ratchet being intermittingly engaged and rotated step-by-step by a pick-pawl 32 fixedly connected with the lower end of an by set-screw 34 in a holder 35 pivoted at 36 to a bracket 37 secured to the main frame, Figs. 1 and 2. On each up-stroke of the builder-arm the pick-pawl engages and advances the ratchet, and thereby turns the shaft 28 to effect a slight outward movement of the traversechanger 16 along the builder-arm, but as the pawl is arranged to impart a gradually Ylecreasing advance movement to the ratchet it is pivotally hung, as has been described, 0 for reasons which will appear hereinafter.

Astop 38 on the bracket 37 is arranged to cooperate with the holder 35 and prevent movement of the pick-pawl 32 to the right, viewing Fig. 1, while said pawl can move in the opposite direction about the fulcrum 36 as a center.

The builder-arm has rigidly attached. to it by lateral brackets 39 a longitudinal rack- 1 bar 4O offset far enough to bring its teeth into mesh with" the drum-gear 14, so that as 'theftraverse-changer 16 gradually moves the a iiidingrdrum 13 toward the free end of the builder-arm the cod eration of the rack-bar and said gear 14 wil slowly rotate the drum 13b to letoif the chain 10 and effect the principal 5 gain of the'traverse. Thus the angular movement of the drum. about its pivotal support 15 determines,'in the main, the amount of gain, such movement. of the drumovercoming or compensating for the slight variations in'the gain due to the change in the posiiion of the drum relatively to the stud 12", ereinbefore referred to, and the amplitude of angular movement of the drum upon the support 15 is directly dependent upon the extent of eachadvance of-the traversechanger 16 away from the fulcrum 18 of the builder-arms So, too, such advance will depend directly upon the rotative'movement.

of the threaded shaft 28 imparted to it by each operativeengagement 0 the pick-pawl and the ratchet 31, and by making the ini- -tial ,or maximnmaction of the pawl and ratchet large enough the gain as a whole will be co trolled absolutely by or through the angularmovements of the drum.

Now the lengthJof the traverse depends upon the position of the'traverse-changer with relation to the fulcrum of the builderarm,-and' as the traverse-changer is moved step-by-step: away from such fulcrum from the. beginn V operation it will'be obvious that the traverse gradually increases in length, butof course fifi with a very small increment. This increg ing to the end of the winding ment is not of itself sufficient, with the slow. letting off of thechain, ordinarily resulting from the action of the winding mechanism to lay the yarn properly at the beginning of the winding, as has been stated, and therefore I have provided means to start the winding with the maximum gain and gradually to decrease the gain automatically as the winding proceeds at the same time overcoming or compensating for the slightirregularity or variation in the gain previously noted.

A slightly bent lever 41 is adjustably fulcrumed at 42 on the builder-arm between its upper and lower flanges and near the plate 27, the under edge of said lever resting upon a rounded and rearu'ardly extended cam-rib 43 on the traverse-changer 16, the fulcrum-stud 42- being fixed in posi- -tion in the vertical slot 44 by a nut 45, see Fig. 5. vSaid lever 41 extends along the builder-arm nearly to the end plate 27 and is then turned laterally to present a foot 4-6, which is arched to extend across and clear the threaded shaft 28, as clearly shown in Fig. 5, the extremity of the foot haviag a slot 47 in which is secured a headed stud 48, held in adjusted position injthe slot by a check-nut 49. The foot 46 is long enough to bring the stud beyondthe edge of'lhc end plate 27*, as shown in Fig. 3.

The ratchet 31 has an elongated hub 31*,

Fig. 3, embracing the projecting end of shaft 28, and upon said hub is rotatably mounted a collar 50, separately shown in Fig. 7, having a head 51 provided with a radial extension 52 having a slot 53 into which the stud 48 extends, the headed collar forming a support for the shield.

The shield 54 is shown as curved and overhanging the ratchet 31 at the right of the pick-pawl 32, Fig. 1, the shield being mounted on an arm 55 secured to or forming part of a hub 56 which embraces the collar 50 between the head thereof and the ra-tchel. said hub carrying a. set-screw 57, seedotted lines Fig. 6, by means of which the hub and the collar are fastened together to turn as a unit.

In Figs. 1, 3 and G the shield is shown in .the position assumed at the beginning of the Winding operation, the traverse changer 11) then being at the right-hand end of its stroke, nearest the fulcrum of the builderarm, and the lever 41 has its foot 46 and the stud 48 in their lowest positions.

Referring to Figs. 1 and 6 it will be apparent that when the shield is in the position shown the pick-pawl 32 will exert its greatest effect upon the pawl 31 and will effect the greatest angular movement thereof on the up-stroke of the builder-arm, because the maximum number of ratchet teeth are exposed to the action of the pawl as the builderarm oscillates, If, however, the

shield 54 be gradually moved to the left, l igs. l and t3, the number of ratchet teeth exposed to the action of the pawl will be decreased, and consequently the pawl will etl'ect a gradually decreasing angular movement o the ratchet and. connected parts. That is, ihe shield will be brought into engagemcnt with the pick-pawl and will push the latter away from a vertical line through the axis of the shaft- 28, so that the pawl can take up a less nui-nber of teeth of the ratchet 31. and such movement of the pawl by the shield is permitted by mounting the pawlrod 33 to swing about the pivot 36 as a fulcrum. As the shield may be set by hand, through the medium of the set-screw 57, the

- angular movement of the ratchet at the beginning of the winding can be increased or decreased at will, according to circumstances, and to properly compensate for the variation in the gain due to out 'ard movement of the drum, but whatever the initial set of the shield there will be a gradual diminution in the step-by-step movement of the ratchet from the maximum. 5

Inasmuch as the rotation of the ratchet controls not only the advance of the traverse-shifter 16 but the rotation of the drum l? to cttect the desired gain of the travverse the. operation will be understood with a brief description of the winding, starting at the commencement thereof.

()n the up-stroke of the builder-arm 17- the" as the cam-rib 43 is thereby moved to the left, Fig. 3, the lever 41 will be acted upon and its foot. 40 will be given a slight rise. This causes .the stud 48 to impart a small angular advance to the collar or shieldsupport: 50 m the direction of the arrow 100,

' Fig. ti, and the shield 54 is moved in the same direction, to uucovea smaller portion o'l' the ratchet. 31 to the action of the pickpawl 32. Consequently the angular movement of the ratchet will radually decrease in amplitude as the winking proceeds, and as the intermittent rotation of the threaded part 25) of the shaft 28 is correspondingly decreased the feed movement of the traverse-changer 16 gradually decreases.

The shorter the feed of the traversechanger the less amount of chain given off from the. winding drum 13, and therefore the less the gain, so that while the gain starts at its maximum it is gradually decreased as the winding progresses, notwithstanding the change in the position of the drum relatively to the stud 12*, and the traverse g 'adually increases, due to the feed of the traverse-changer away from the fulcrum of the builder-arm. The diminishing gain thus acts in connection with the increasing traverse to lay the yarn upon the yarn-receiver or bobbin 1), Fig. 8, with a taper from the lower end of the yarn-mass upward, as at m, to the substantially cylindrical body portion m of the yarn-mass, with an inward taper m" at the upper end thereof. A full winding of yarn is secured, with the yarn-mass of the desired shape, and so laid that the varn draws oti' smoothlv and evenly down to the very beginning of the 'windmg, the layers at the beginning of the the lever 41, and to preserve the proper relation between such parts the fulcrum 42 of the lever 'will be slightly raised in the slot 4st.

By setting the stud 48 toward or away from the center of the shaft 28 the angular movement of the shield 54 will be increased or diminished, respectively, for a given rise of the stud as the lever 41 1s swung up about its fulcrum by the feed of the traversechanger, to thereby retard or hasten the rate of change in the gain As to the traverse, while it is gradually increasing throughout the. windin its rate of increase is gradually decreasing, for it. must be remembered that the steps by which the traverse-changer is fed toward the outer end of the bnilde '-arm are greatest. at the beginning of the winding and gradually decrease. in length as such winding proceeds.

in view of the foregoing description and explanation of the operation of certain parts of theapparatus, having more particular reference to the gain of the traverse and its control, it will be manifest that the gain is controlled, broadly, by means mounted on the builderarm and acting upon the ringrail through the connection between the lat- :ter and the builder-arm.

This apparatus does not wind whatis technically known as a bunch by a preliminary windin of the yarn, as is done by some other builder-motions, the yarn-mass being completed by a main or service Winding, but in actual practice the first few layers of yarn lald upon the yarn-receiver by the present apparatus can in practice be utilzed in as feeler loom to perform the funcparting from the spirit and scope of my present invention as'set forth in the claims annexed hereto.
