In general, the present invention comprises a spindle or other means for holding a bobbin or'the likein delivering position, a chute or runway for transferring the bobbin to the spindle, means for manually operating the spindle to dofi or eject a spent. bobbin, and

automatically-operated means to return the spindle into position to receive a fresh bobbin and to thereafter move it into'delivering po sition. The invention also contemplates the use of a traveling belt or. conveyor associated with the bobbin-receiving chute to continuously supply bobbins in position tobe placed in the chute to transier them to delivering position.

\ The invention as herein shown is applied to use one winding machine for winding thread, yarn and other strand material, but

the device .is also adapted for use on other typesml textile apparatus in which yarn or the like is transferred from one carrier to another in various and sundry processes of the textile art.

Referring to Fig. l of the drawings, the

winding machine as herein shown is supported on-legs or standards 2 and comprises a plurality of heads or units surmounting a horizontal bed or frame 3 extending between the legs. The winding mechanism as herein illustrated by way or example comprises a drum or drive-roll 5 for rotating the cop or package which is wound on a mandrel or the end of a swinging arm 7 which is pivoted at 8 to an upright 9 on the machine frame,

' the package being thus supported with its periphery in contact with the drive-roll 5 to adapt it to be driven therefrom as its axis recedes from the roll during the increase in diameter of the winding. The strand of yarn or other material, indicated at y, is traversed longitudinally of the cop-holderfi during the rotation of the latter by means of a reciprocating thread-guide 10. The thread-gu'de 10 is mounted to slide on horizontal tracks or ways 11 and 12 and connected thereto is a bowl or roller 13 which engages a helical groove 14 in the rotating cam 15 wherebyto reciprocate the guide. The construction of the winding mechanism as above described is well known to those versed in the present art and is therefore not herein illustrated in detail.

Each unit of the winding machine is usually' vprovided with a tension-device for applying resistance to the draft on the yarn as 1t feeds to the cop or package being wound, and the present drawings illustrate adisktension for this purpose. In Fig. 1 the tension-device is shown as mounted on a bracket 17 which is bolted to the front of the frame of the winding machine at 18 andprovided with a horizontal shelf or rest 19 supporting a vertical spindle 20. A pair of tension-d'sks 21 are mounted on the spindle 20, and a weight-holder 22 slidable on the spindle thereabove carries a suitable number of weights 23 which apply pressure to hold the tension-disks against the strand of yarn drawing therebetween. A spring'24 is preferably interposed between the weight-holder 22 and'the upper tension-disk to provide for the separation of the tension-disks whenknots and enlargements pass therethrough without moving t e tension-weights.

The strand of yarn y leads through an opening or guide-eye 26 at one side of the shelf 19 and draws across the top of the shelf to feed between the two tension-disks 21. From the tension-disks the strand 3 draws through a suitable slub-catcher 27, as usually provi ed, and thence leads to the threadguide 10 to be fed therefrom and traversed thereby onto the cop or package being wound.

In delivering am or other strand material from cops, obbins and other types of headless packages, the strand is usually drawn off over the end of the package and for winding machines the supplies are generally arranged below the winding units with their axes in line with the point to which the yarn draws as it feeds through the tension-device. In the present application of the invention to a winding machine thesupply-holders, one for each winding unit, are supported from a horizontal rod 28. which extends between arms or brackets 29 attached to the legs 2.

As shown in Fig. 1, the brackets 29 are his tened to the we of the legs 2 by means of clamps 30 secured in' place by bolts 31, and the rod 28 is held in hubs 32 at the ends of c the brackets by means of set-screws 33.

A series of inclined arms or brackets 34 are bolted to the front of the frame of the wind-' ing machine to extend outwardly above the brackets 29. Thebrackets 34 serve as upper supports for the chutes and runways into which the bobbins are placed and down which of the machine and is thereby continuously i i they slide to apply them to the spindles or driven to travel it longitudinally of the trough. The traveling belt 37 is provided asa means for conveying'bobbins from a source of supply into convenient position to be picked u .by the operator and placed in the chute w ich delivers them to the supplyholder. The bobbins may be fed to the conveyor-belt from a suitable hopper, not shown, or by manual means as desired.

The bobbin-chute 40 comprises a pair of wing-like sections or plates 41 curved to conform to the shape of the bobbin B and supported on upright inclined rods 42 and 43. The upper ends of the rods 42 and 43 are held in bosses or hubs 44 projecting from an arm or bracket 45 which is attached to the trough '35 by means of a screw or screws 46 extending through an overhanging flange 47 on the side of the trough. As shown in Fig. 3, the rods 42 and 43 are secured in the hubs 44 by means of set-screws 48 and the plates or wings 41 have hubs 49 surrounding the rods and fastened thereto by means of set-screws 50, see Fi 7. The plates 41 are thus rigidly attac ed to the rods at their upper ends while their lower ends have ears or projections 51 bearing against the sides of the rods to hold them in position thereon. The sides of the chute 40, comprising the wings or plates 41, are flared outwardly at the top to facilitate the insertion of the bobbins thereinto and as each bobbin slides through the chute it is guided by the two rods 42 and 43 in the manner as later more fully explained. It will be noted by reference to Fig. 7 that the roddesignated 42 is of hollow or tubular con-j struction whereby to adapt it to receive ahorizontal rod 28, before referred to. The

bracket 53 has ahub 54 encircling the rod 28 the hub 54 are two arms 56 formed with bosses at their ends bored to receive the rods 42 and 43 whichare secured fast therein by means of set-screws 57, see Fig. 5.

The plunger-rod extends downwardly through the hollow rod .42 and is bent at its lower end to form a right-angled arm 61 which projects outwardly between two lugs 62 on the under side of one of the arms 56 and then extends laterally in the direction of the rod 28. The two lugs 62 prevent the rod 60 from turning within the hollow rod 42 and the arm 61 provides means for operating the control-mechanism of the bobbin-spindle in the manner as later explained. Secured to the upper end of the plunger-rod 60' is a finger piece or push-button 65, beneath which is a elical spring 66 coiled around the rod. The spring 66 bears against a washer 64 arranged above the boss 44 in which the hollow rod 42 is held and serves as a means for normallyholding the plunger-rod in raised position, as shown in Fig. 1, with its arm 61 hearing against'the bottom of the bracket 53.

The bracket 53 serves as a supportfifor a bearing-member 67 which carries a pivot for rockably mounting the bobbin-spindle As shown most clearly in Figs. 4, 5 and 6, the bracket 53 is provided on one side with a rectangular portion 71, to which is bolted the member 67. The member 67 is formed with a longitudinal slot 68 through which extends a bolt 72 screwed into the bearing 71. The purposeof. the slot 68 is to provide for lateral adjustment of the member 67 which supports the spindle so that the latter may be set at different distances from the rods 42 and 43 in accordance with the diameter of the bobbins being used as supplies; it being understood that the bobbins slide down the runway formed by the rods 42 and 43 to impale them on the spindle 70.

On the bottom of the member 67 is a hub 73 which receives the reduced end of a pivotstud 75 held in'place in the hub by a set-screw '7 6, see Fig. 5. Pivoted to turn on the headed end of the stud 75 is a disk-like member 77 formed on its periphery with a socketed hearing 78 in which the end of the spindle 7 0 is stepped and held in place by means of a setscrew 79. The disk 77 is provided with a radial arm 80 formed with a weight 81 at its end which acts to rotate the disk on its pivot to move the spindle 70 from normal delivering position, shown in Fig. 1, down into inclined position as illustrated in Fig. 2, whereby to eject the spent bobbin-tube or yarn carrier 6 03 from its end. The disk or rotatable member 77is maintained with the spindle 70 in vertical position while the bob-- bin B isdehvermg its material by means" of a latch 85 which engagesa suitable detent-shoulder 86 on the periphery of the disk,

see Fig. 1.

The latch 85 shown in detail in Fig. 9, is

pivoted on a pin 87 fastened in a boss at the rearward end of the member 67 by means of a set-screw 88, see Fig. 6.. The latch '85 is formed with a weighted arm 89' projecting rearwardly from its hub and is provided with a forwardly and upwardly curved arm 90 which terminates in a fork 91, shown most clearly in Fig. 4. The fork 91 straddles the sides of the spindle 70 when the latter is either in vertical or slightly inclined position to adapt the latch 85 to be struck by the end of the bobbin-tube or carrier 5 as the latter slides down the runway and is impaled on the spindle. @n the underside of the latch 85 is a tooth or projection 92 which engages with the detent shoulder 86 on the periphery of the disk 77.

The periphery of the disk 77 is formed with a second notched shoulder 93 which is engaged by the toe 94 of a pawl 95 pivoted on the pin 87 on which the latch 85 is mounted. The pawl 95 has an arm extending rearwardly and downwardly from its pivot which provides a weight for holding its toe-portion 94 against the periphery of the disk 7 7 The upper forward edge 96 of the pawl 95 is adapted to be engaged by an abutment or shoulder 97 on the side ofthe latch 85, whereby when the latter is rocked by the engagement of the bobbin 5 with its forked end 91 the pawl 95 will be released from the notch 93 in the disk 77 to allow the weight 81 on the disk to turn the latter to shift the spindle. 70 from the plunger-rod 60 is normally maintained in position above the weighted arm 89 of the latch 85 so that when the finger-piece or push-button'65 is pressed to slide the rod downwardly the arm will act against the top of the weight to rock the forward end of the latch 85 upwardly to release its detenteprojection 92 from the shoulder 86 on the disk 7 7. As these detents are released the disk 77 will turn under the action of its weight 81 to swing the spindle 7 0 from the position shown in Fig. 1 to dofing position illustrated in Fig. 2. The

method of operation of the complete device is 7, therefrom led up through the guide-eye, 26 and thence drawn through the tension. device to the thread-guide 10. the winding proceeds in the usual manner. The'end of the strand being attached to the cop-holder 6 thelatter is lowered to place its periphery in contact with the rotating drive-roll 5 and the roll will therefore frictionally drivethe 'cop-holder'to wind the 'yarn thereon with osition shown in Fig. 3 to that illustrated in ltd lid

tea g weighted tail-piece or arm 89 of the latch 1 9 at such an angle that the tube 5 will drop bobbin.

the thread-guide 10 traversing the strand back and forth to deposit it in helical coils which build up in layers to form the package. As the winding proceeds and the yarn is taken oil from the bobbin B, eventually the end will run out and the operation of the machine is arrested through the automatic action ofinstrumentalities as usual] provided, but not herein shown or describe The spindle is normally maintained in vertical relation to support the bobbin B in delivering position by the action of the weight 81 which holds the disk 77 with its notch 86 engaged by the detent-projection 92 on the latch 85, see Fig. 1'.

When it is observed that the yarn on the bobbin B is almost exhausted t e operator assumes a station at the front of the suply-holder and immediately the winding has een arrested the push-button or finger-piece 65 ispressed downwardly to project the plunger-rod 60 through the hollow rod or tube 42. The downward sliding movement of the rod 60 carries itsarm 61 against the 85 to rock the latter into the osition shown in Fig. 2 whereby to release its detent-proection 92 from the shoulder 86. As the disk 7 is thus released from the latch 85 the weighted'arm 80 will turn it on its pivot to swing the spindle 70 to the right and downwardly into the position illustrated in Fig. 2 of the drawin It .will'be understood that as the weight 81 swings across center its momentum will carryit therebeyond, its motion being augmented by the. weight of the spindle 70 and the bobbintube 6 to continue the clockwise rotation of the disk 77 until the spindle is inclined off from its end..- A suitable bobbin-box or other receptacle, not herein shown, is usually placed below the-supplv-holders to receive the empty bobbin-tubes or yarn-carriers as they are ejected therefrom.

. Now, after thedisk 77 has been turned into the position shown in Fig. .2 and the bobbintube dotfed or ejected therefrom, the mo-' mentum of the weight 81 isfinally overcome.

and the arm 80, acting as a pendulum, swings the disk back in the opposite direction. This return movement of the weighted arm 80 carriesthe disk 77 around until the toe 94 on the pawl 95 snaps into engagement with the notch 93 in the edge of the disk. The disk 77 ,is thereby locked in the position illustrated in Fig. 3 of the drawings to hold the spindle 70 in parallel relation to the rods 42 and 43 which form the runway for the Stated briefly, after the dofiing of the empty tube 6 the disk 77 is automatically swung back under the action of the weight 81 to aline the spindle 70 with the axis of the bobbin-chute 40.

It will be understood that immediately the detent-latch 85 has been disengaged from the shoulder 86 on the disk 77 the finger-piece the traveling belt or conveyor 37 and entering it through the top of the chute, releases it to permit it to slide down the runway. As the bobbin B slides down on the rods 42 and 43 the end of the bore in the tube 1), which is usually beveled orbelled outwardly as shown at m in Fig. 3,v rides over the rounded end of the spindle 7 O and is impaled'thereon. The bobbin B gains momentum as it slides down the runway and aided by the action of gravity the end of the tube 6 strikes against the forked end 91 of the latch 85 with some force. This impact of forked end 91 downwardly with'a quick action and its lateral shoulder or abutment 97 strikes against the forward end 96 of the pawl 95 to rock thelatter to release its toe 94 from engagement with the notch 93 in the disk 77. The disk 77 is thereby released to be acted upon by its weighted arm 80 which tends to swing it in a clockwise direction. In the meantime, however, the latch 85 has been carried down until its projection 92 brings up against the periphery of the disk 77 and consequently the disk is turned only to a slight extent, or until the shoulder 86 on its edge brings up against the projection 92 on the latch. This last turning movement of the disk 77 carries the spindle 7O into vertical position where it is held locked by the latch 85 to maintain the bobbin B erect with its axis alined with the guide-eye 26 of-the tension-device, see Fig. 1. It will thus be apparent that after the dofiing of the empty bobbin-tube 6 through the manual operation of the push-rod 60 the bobbinholder is first turned into position to receive a fresh bobbin as it slides down the runway, and then'the action ofimpaling the bobbin on the spindle 70 releases the disk 77 to permit the spindle to be carried back into vertical position.

It will be observed fromv the foregoing that the invention provides a bobbin-holder which is almost entirely automatic in operation, the operator having only to press the button to effect the dofling of the empty bobbin-tube and to then place a fresh bobbin in'the chute to cause it to be impaled on the spindle and carried into delivering position.

The bobbin-chute is placed conveniently in advance of the tension-device of the winding wound. It will be observed by reference to. Fig. 7 that the side of the chute 40 is open cause it to be drawn between the tension-disks and into the slot of the slub-catcher without further attention on'the part of the operator.

The provision of the traveling conveyor adjacent the several bobbin-chutes arranged supplies, the bobbins being continuously'fed into position at the front of the bobbinchutes so that the operator has only to lift them off therefrom without stooping or reaching. The invention thus provides for a substantial saving in the time usually spent in dofiing the spent bobbins and supplying fresh ones in their place, it requiring only a few seconds to drop the bobbin into the chute and draw its end to the winding mechanism. Furthermore, the operator does not have to bend over to lift the bobbin-tube off from its spindle and thereafter place a fresh bobbin thereon, and thus less effort and energy is used and the operators strength conserved for other duties.

Recently there has been a notable trend 1n the winding art to greatly increase the speed of operation of the winding machines and, obviously, when the machines are stopped for replenishing the supplies the loss' of production is correspondingly greater. Conse uent- 1y, a saving in the time required for ofling spent supplies and placing new bobbins in delivering position is reflected in a proportionate increase in theproductiveness of the machine. The present invention therefore provides an important improvement in the art as economizing in time and labor and 1ncreasing the productive capacity of the machine.
