$PINNIIIG 0E WINDING MAUI-11H E.

. 0 uZZ whom. it may concern:

. L known that .l, Hanna? A; LEONARD, a citizen of the United States, residing at Hopedale. in the county of lVoij'cester and State of iilassachusetts, h ve invented an linprovement in Spinning: or "B inding Machines. of which thefollowing description, in connection with the accoinpan i 1 inns, is a specification, like characters on the drawings representing like parts.

This invention relates to machines for winding yarn on yarn receivers, and .more particularly to machines for winding the yarn on the yarn receivers for use as weft or iilling' in feele looms.

ln one type of feeler looms now extensively used, it is the usual practice to replenish the filling prior to complete exhaustion of that in the running shuttle This replenishment maybe effected either by sulr stituting for the shuttle in play another having a supply of filling init, or by ejecting the yarn receiver or carrier in the shuttle and substituting another having a working supply of yarn or filling thereon.

In order that perfect cloth may be woven, it necessary that the final piclr prior to replenishment shall be a full pick that is. that a full length of filling or weft thread shall be laid throughout the width of the shed; and to effect this it has been usual heretofore to cause the feeler mechanism to call the chan e and replenishment when there Stilt remained upon the yarn re ceiver or carrier a greater length of filling than necessary to provide a full final pick and tension on the final pick laid in the shed. Any surplus yarn or filling remaining on the eiected varn receiver or carrier constitutes waste. and economy in the production of cloth dictates that such waste be as small as possible, consistent with the desired results.

In some types at feeler looms, it has been suggested to provide the yarn receivers or carriers with a bunch of yarn or filling, and to have cooperate therewi h the feeler mechanism to effect a change of filling}; when the bunch has been reached. The. bunch, however,usually contains more filling than is necessary to lay a final full pick, and moreover, difficulty is experienced in providing; filling carriers or receiverswith a bunch properly located and of proper amount. In forming; the bunch the oraw- Specification of Letters Patent. Pwmgnitqgqfl Apr 11, 1922. Application filed January 17, 1921. Serial No. 437,749.

practice to traverse the yarn or filling l0ngiriers and to then pass to the full service traverse after the bunch is completed. This expedient is liable to cause the ends (that is, the yarn) to be broken, and is otherwise objectionable.

An important feature of the present invention, therefore, consists of means for providing the yarn receivers or filling carriers with a reserve supply of filling sufficient in amount to insure a final perfect pick prior to the change of filling, and to Wind the reserve supply upon the filling carriers or receivers without traverse and then to resume the traverse when the reserve supply has been wound.

A further important feature of the invention consists in means for rendering the traversing mechanism ineffectual during the winding of the reserve supply of filling on the yarn receivers or carriers and to bring the traversing mechanism automatically into action when such reserve supply has been Wound.

The amount of reserve supply that is Wound upon the filling carriers without traverse should vary under certain conditions, and another important feature of the present invention, therefore, consists in means for predetermining the number of windings that shall be wound upon the filling carriers or receivers to constitute the reserve supply without the traverse.

When the traversing mechanism is brought into action to lay the yarn upon the yarn receivers or carriers with a traverse longitudinally thereof, it is desirable that the winding of the yarn up-on the yarn receivers or carriers be commenced at the base of the filling carriers or receivers; and another imof a machine for winding yarn upon yarn receivers, showing the present invent-ion associated therewith;

to support one or more spindles for rotating the yarn receivers or bobbins 4, on whichthe yarn is to be wound. As the yarn is wound upon the yarn receivers or bobbins 4, it is directed thereto by the yarn guiding means which, in the present instance, consists of a ring-rail 5 carrying one or more rings 6 on which are the travellers 7, through which the yarn passes from a source of supply to the yarn receivers or bobbins 4.

When the yarn receivers or bobbins are to be supplied with yarn to be used as the filling or weft in the loom, the yarn is given a traversing movement longitudinally of the receivers or bobbins of a predetermined amount, and the path of such traversing movement is gradually changed from near the base toward the tip end of the yarn receivers or bobbins, in order that the yarn may be laid upon the yarn receivers or bobbins by a filling wind.

Depending from the yarn guiding means or ring-rail 5 are the lifter rods 8, of which there may be one or more, the lower end whereof rests upon a roll or stud 9 carried by an arm 10 mounted at 11 on a bracket 12 supported by the machine frame, Fig. 1. Since the weight of the yarn guiding means or ring-rail 5 is considerable, it is usual to counterbalance the arm 11 by weights (not shown) mounted on a counterbalancing arm 13; but since such counterbalancing feature is old and well known, its further illustration is not deemed necessary.

Mounted on the shaft 11 in fixed relation .to the arm 10 is the arm 14, to which is con- I nected at 15, the traversing mechanism. The Fig. 3 is a -perspe'ctive view with certain which, in effect, forms part of the builder arm 17. There is an adjusting screw 20 between the arms '17 and 19.

The arm 19, which as above described, constitutespart of the builder arm, is provided with a roll 21 which bears-upon a .buildercam 22, the construction being such that as the builder cam rotates, its periph eral cam surface 23 will cause the builder arm to oscillate upon its pivotal support 16. The roll 21 carried by the builder arm,

is held in contact with the. builder cam by means of the weight of the ring rail and connected parts.

Mounted for rotative movement on the builder arm is the builder screw 26, Figs. 1 and 3, upon which is the travelling threaded head or nut 27 A flexible connection or chain 28 is secured to the heador nut 27 and passes over a roll 29, Figs. 1 and 3, from which it leads to a link 30 secured to the arm 14 by adjustable connection 15 hereinbefore referred to,

From the construction thus far described, it will be apparent that upon rotative movement of the builder cam 22, the builder arm will be oscillated on its support, and through the chain 28 and connections, will cause traversing movement to the ring-rail or yarn guiding means 5.

In order that the traversing movement imparted to the ring-rail may be shifted longitudinally of the yarn receivers or carriers, or given a gain toward the end of the yarn receivers or carriers, the builder screw 26 is given a rotative movement through means that will now be described.

The builder screw 26 has secured to its lower end the bevel gear 31, Figs. 1 and 4, which meshes with a bevel gear 32 carried by the shaft 33, Fig. 4, which is rotatably mounted in the bearing 34. The shaft 33 has mounted thereon the pick wheel 35, Figs. 3 and 4, which is connected to the shaft 33 to rotate therewith. The bearing 34, Fig.4, is extended to form a bearing for a sleeve 36, to which is fixed the chain wheel 37. The sleeve 36 has the disc 38 secured thereto and carries the working pawl 39, best shown in wheel is rotated by the actuating pawl 39 from the sleeve 36, the holding pawl 40 will prevent retrograde movement of the pick wheel.

The chain wheel 37, Figs. 1 and i, has se cured thereto one end of a chain or flexible member 41, which passes around a guide wheel 42 mounted on the machine frame at 43, Fig. 1, and thence the chain passes downwardly about a roll 44 mounted on the part 19 of the builder arm, and the end chain is connected at a fixed point 455 which, in the present instance, is the front bearing of the cam shaft 46. From the construction described, it will be apparent that upon actuation of the builder cam, the builder arm will be oscillated and through the mechadescribed, the builder screw 26 will be rotated to'vary the path of travel of the yarn guide or ring-rail 5, and the yarn will be laid upon the yarn receivers or bobbins with a traversing movement which gradu ally approaches the tip end portion of the receivers or bobbins, or in other words, with a filling wind.

The present invention contemplates that the yarn receivers or bobbins shall have wound upon them a reserve supply of yarn without traverse of the yarn longitudinally of the yarn receivers or bobbins, and that the traverse mechanism shall then be rendered efiective to continue the winding of the yarn upon the yarn receivers or bobbins with a traverse longitudinally of the yarn receivers or bobbins.

The builder cam 22 is mounted upon the cam shaft 46, Figs. 1 and 3, and has depressions 47, of which there may be one or more, three being shown in the drawings. These depressions 47, when engaged by the roll 21 of the builder arm, and when the screw head or nut 27 is in its upper position, Fig. 3, indicate that the yarn guiding means or ring-rail is at its lowest position.

Secured to the cam shaft is the worm wheel as, Figs. 3 and 5, through which a train of mechanism operates to actuate the builder cam.

Rotatably mounted in the sleeves 49 and 50 is the operating shaft 51, Figs. 5%, Sand 6. The bearing 50 is mounted on the brackets for rocking movement about the pivotal connection The bearing 49 is carried by the arms which are secured to the shaft Figs. 5 and 6. The arms 54 are preferably connected to the bearing 49 by means of the rod 56, which is extended to one side of the bearing i9 and there connected as at 57, Fig. 6, to a weight carrying arm 58 which is itself loosely mounted upon the shaft as shown in Figs. 5 and 6, and is provided with astop 61 which limits the clockwise movement of the arms 5% about the supporting shaft 55. is a further means for supporting the weight when it is in its lowered position, as indicated in Fig. 5, a buffer pin 62 is mounted on a bracket 63 and rests upon a spring 64, the tension of which may be adjusted as nesired, by a set screw 65.

Secured to the shaft 51 is the worm 66 which is adapted to be en 'aged with and disengaged from the cam operating worm wheel as, the construction being such that when the weight 60 is in its lowered position as indicated in Fig. 5, the shaft 51 wi i be lowered to cause the worm 66 to be engaged with the worm wheel 48; but should the weight 60 he lifted, the bearing 4-9 carrying one end of the shaft 51 will likewise be lifted. through the arms 54:, and the worm 66 will be disengaged from the cam operating worm wheel an d the cam will be freed from its ope means. Under the conditions last stated, that is, when the cam 22 is not being operated, the yarn guide or ring-rail will not be traversed longitudinally of the yarn receivers or carriers, and consequently any yarn wound upon the yarn receivers or carriers at such time will be wound thereon without traverse. Tnasmuch, also, as the roll 21 of the builder arm rests against the builder cam 22, when the builder cam 22 is freed from its operating means it will be caused to rotate to place the roll 21 in one of the depressions a? of the builder cam, with the result that yarn wound upon the yarn receivers or carriers without traverse, as described, will be wound upon the yarn receivers or carriers at the base portions thereof.

The shaft 55, Fig. 3, is extended laterally. and has its end portion 67 supported in a bearing in the machine frame, 1* 19s. 1 and Secured to the shaft 55 is the hub portion (38 of an operating'arm 69 which is preferably formed integral with the hub, as indicated in Fig. 3. The hub 68 may be secured to the shaft 55 by any appropriate means such as the set screws 70. The operating arm 69 has a tloot-piece 71, Fig. 1, adapted to be engaged by the foot of the workman for rotating the shaft 55 under manual control, the construction being such that should the'attendant dcpress the foot-piece 71, the shaft will be rocked, thereby lifting the weight-carrying arm 58 and disengaging the worm 66 from the worm wheel 48.

After a suflicient reserve supply of yarn has been wound upon the yarn receivers or bobbins without traverse, as above explained, it is desirable that the main windings placed upon the yarn receivers or carriers be started with the desired filling wind traverse, and to this end the present invention provides auto matic means for engaging the builder cam with its operating means after the reserve supply of yarn has been wound upon the yarn receivers or carriers.

The shaft 51 may be rotated from any suitable source of power, and as shown in the present instance of the invention, the shaft 2O 53 hereinbeftore describe 51 has sprocket wheel 72 about which passes a sproclret chain 78. and by which the shaft 51 is rotated.

Mounted ior rocking movement about the 5 supporting rod or shaft 74:, Figs. 1, 3 and 5,

is the latch 75, the upper portion 76 of which is adyustably connected to the lower portion by a slot and bolt adjusting means 74. The latch 7 5 has a weight supporting 10 shoulder 78 which. when the weight 60 is raised as hereinbe'lore explained,is CtIIlBCl beneath the weight 60 by means such as the weighted arm 79 of the latch. The weighted arm?!) provides a convenient form of means for throwing the latch into the weight-supporting position, as indicated in .llig. 8, but it will be understood that any equivalent means such as a spring for instance, might be employed instead of the weight T9. The bracket may be convenientlysecured to the latch 75, as indicated in'Fig. 5, by the adjusting bolt 80.

W hen the weight 60 is engaged with the shoulder 78 and the reserve supply of yarn is being wound upon the yarn receivers or carriers without traverse, it is desirable to trip the latch automatically and free the weight to cause the builder cam operating mechanism againto become effective. To

this end the upper portion 76 of the latch has adjustably secured at its upper end the trip 81. Adjustment of the trip 81 with relation to the arm 76 may be variously effected, but in the present instance of the invention the trip 81 is provided with a slot '82 through which passes the securing bolt 83, Figs. 1 and 7.

Secured in the brackets 8d, mounted on the machine frame adjacent the shaft 51 are the 40 Tguide rods 86 on which is mounted the trip slide or carriage 87, the lower face portion of which is provided with a series of teeth 88, Fig. 7. The trip slide 87 is normally under the influence of a spring 89, one end of which is connected to the slide at 90, and the other to a fixed part as at 91, the construction being such that the slide 87 will normally be held in a position indicated in Figs. and 7. A buffer spring 92 may be interposed between the slide 8'? and the bracket 84; to absorb the shock when the slide is freed for the action of the spring 89 as will presently appear.

The cam operating'shatt 51 has secured to it a second worm. 93, Figs. 8, 5 and 6, which 55 is normally below the teeth 88 of the trip slide 87, but when the shaft 51 is moved upwardly to disengage the shaft 51 from the train of mechanism between it and the builder cam, it will be brought into engage ment with the teeth 88 oi the trip slide 87 Under the conditions stated, the trip slide 87 will be thereupon moved along the guide rods 86, since the shaft 51 continues in operation. The trip glide 87 carries a pin 94 which is adapted to engage the trip 81 when the-trip slide has been moved the predetermined extent. -The trip 75 will be turned about its axial support '74, to the right, Fig. 5, or to the left, Fig. 1, by the pin 9a, and the weight 60 will be released, thereupon lowering the bearing49 and bringing the worm 66 into operative engagement with the worm wheel l8 and starting the builder cam and traverse mechanism.

Since the trip 81 is a usta-bly secured to.

1 the latch or upper member 76 of the latch, it follows that adjustment of the tr p 81 Wlll determine the number of windings that hall be made upon the yarn receiver or carrier to constitute the reserve supply of windings without traverse; and when the .latch has been tripped as here'inbctore described, to permit the weight 60 to drop, the worm 93 will be disengaged from the trip slide 8? and the latter Will be moved to its initial position, Fig. 7, under the impulse of the spring 89.
