Further objects of the improvement are set forth in the following speci?cation which de scribes a preferred form of construction of the invention, by way of example, as illustrated by the accompanying drawings. In the drawings: Fig. 1 is a front View of a conventional type of winding machine showing the present im proved supply holder as applied to use therewith; Fig. 2 is a plan view of the supply holder shown in connection with thetension-device with which it cooperates; _ Fig. 3 is a side elevation of the supply holder showing the bobbin chute or runway in section; Fig. 4. is an elevational view of the supply hold er looking inthe direction indicated by the ar-_ row 4 in Fig. 2 and showing a supply-bobbin in position to deliver the yarn tothe winding ma chine; v Fig. 5 is a View similar to Fig. 4 illustrating the manner in which the-empty bobbin is doffed or ejected from the supply-spindle; and ' Referring to the drawings, the winding ma chine herein illustrated, by way of example, is of conventional type in which the package is ro tated by peripheral contact with a drive-roll or drum. The present supply-holder is adapted for use with practically all types of Winding and like 25 machines however, and thereforethe illustrated machine will be described only briefly as relating to the operation of the improved device. A plurality of winding ‘units are usually mounti ed upon a bed or frame 2 supported from the 30 ?oor by legs 3 spaced along the machine. The bed 2 carries brackets 4 which, in turn, support bearings for the rotative elements of the winding mechanism. The winding mechanism of the in dividual unit herein illustrated comprises only 35 two principal elements, namely, the winding mandrel or spindle 5 on which the yarn-receiver or cop-tube C is rotatably supported and the drive-roll l0 for rotating the yarn-receiver; and in which is embodied means for traversing the’ 40 yarn back and forth axially of the package being wound._ This particular form of traversing means is fully shown and described in United States Letters Patent No. 1,749,355, dated March 4,1930. The drive-rolls ID for the several winding units 45 are carried on- a horizontal shaft I3 J'o-urnaled in bearings supported by the brackets 4 and con tinuously driven from a suitable source of power. Theimachine is herein shown as adapted for ‘winding packages of conical form vin which the 50 yarn body or_ package is built up on a ‘suitable core or receiver, a wooden or ?ber cone 0 being illustrated as mounted to rotate on the winding » spindle I 5.

The chute or runWay‘I'SOVprovidesmeans 375 2,124,499‘ for guiding a full bobbin B into place on the supply-spindle 50 when it is desired to replenish the supply. The chute 90 is inclined to the V81‘? tical at a slightly greater degree than the spindle Cl 50 to provide that after the bobbin B has slid down the chute into position with its lower end impaled on the end of the spindle, further sliding movement of the bobbin will cause it to tilt up wardly away from the chute as shown in Fig. 3. The, improved supply holder having now been de scribed in detail its method of operation will next be explained. Assuming that a full bobbin B is in place on the spindle 5!! of the supply holder as shown in 15 Fig. 1 of the drawings, the strand y is drawn up wardly through the slit 28 in the bracket 25, threaded between the tension-disks 21, laid across the traverse-roll I I] and its end attached to the cop-tube C. The spindle-arm I5 is then lowered 20 to place the periphery of the cop-tube C in con tact with the rotating drive-roll Ill. The roll [0 rotates the cop-tube to wind the yarn thereon as the grooves in the roll traverse the strand back and forth to deposit it in helical coils which As the winding proceeds and the yarn is taken off from the bobbin B, eventually the end will run out and the operation of the machine is automatically arrested through the action of a suitable stop 30 motion, not herein shown. The supply-spindle 50 is normally maintained in substantially vertical position, as viewed in Fig. 1, under its own weight and that of the bob 25 build up in layers to form the package. bin B and the arm 41 with the arm resting 35 against the stop 16. Owing to the‘ inclination of 3 droponto a'traveling conveyorwhich removes them from the machine. 1 ‘It is to be particularly noted that although the ejection. of the bobbin is above explained as being caused by the action of the ejector-member 60, the use of this element is .not essential. That is to say, if the spindle 50 is swung upwardly rapid ly, as provided for by the relatively short leverage of the arm 64 to which the push-rod 65 is con nected, the force of momentum will propel the bobbin 01f from the end of the spindle. On the other hand, the ejector-member 60 is provided 10' as a precautionary measure to insure a positive ejection of the bobbin should the operator press the push-rod 65 down too slowly. ' 15 Immediately the empty bobbin 1) has been doffed'in the manner as above-explained the op erator releases the push-button 10 and the weight of the arm. 4‘! and the parts carried thereby re turns the member 45 to ?rst position as illus 20v trated in Fig. 4, with the arm 41 resting upon the stop 16. During the return of the member 45 the counterweight 55 acts to control its movement to prevent rebound as the arm 41 strikes the stop 16. With the arm 41 at rest the supply-spindle 25 50 will again be alined with the delivery point 23 of the tension-device l8 to insure proper delivery of the yarn thereto. It will be understood that during the return movement of the parts in the - manner above explained the ejector-member 60 swings downwardly about its pivot 51 under the action of gravity to position its pointed end 6| in the recess 54. After the supply-spindle 50 has been returned‘ to ?rst position the operator places a fresh bob 35 bin B in the chute 9|] and releases it to permit it to slide downwardly under the action of gravity the stud 43 the spindle 50 is‘ inclined slightly with respect to a vertical plane extending longitudi nally of the machine, see Fig. 3, to provide that the bobbin B will be axially alined with -the deliv 40 ery point 28 in the tension-device l8. It will be observed by reference to Figs.'1 and 4 that with a bobbin B in place on the spindle 50 the pointed end 5| of the ejector-member 60 is positioned impale it thereon. Due to the angular relation ship of the chute 90 to the spindle 5|] the bobbin in the recess 54 of the arm or extension 41 be 45 neath the head of the bobbin. . When it is observed that the yarn on the bob B is canted upwardly away from the chute as it slides onto the spindle in the manner indicated 45 by full lines in Fig. 3 to aline its axis with the bin B' is almost exhausted the operator takes his station at the front of the supply holder and immediately the winding has been arrested the‘ 50 push-button or ?nger-piece 10 is pressed down wardly. The downward sliding movement of the control-rod 65 rocks the member 45 on its pivot 63 to cause the arm 41 to rotate in a clockwise 55 direction as viewed in Figs. 1, 4 and 5. This movement of the member 45 is aided by the counterweight 55 so that only a slight pressure is required on the push-button 10 to perform the operation. As the arm 41 and spindle 50 are 60 swung upwardly the ejector-member 60 moves with them until its toe 62 strikes the stop 80. Further upward movement of the arm 41‘ causes the ejector-member 60 to be rocked upwardly about its pivot 51 with a quick action. The 65 movement of the ejector-member 60 is more rapid than that of the spindle 50 and its toe 6| ejects the empty bobbin 1) from the spindle 50 and propels it to one side of the supply holder 70 or in the direction indicated by the arrow in Fig.v 5. The swinging movement of the several parts is limited by the engagement of the push-button ‘it against the projection 61 of the collar 68. A box or like receptacle may be provided to receive 75 the ejected bobbins b or in other cases they may while he holds the end of the yarn. As the bob-» bin B slides downwardly in the chute in the man ner indicated by the dash lines in Fig. 3 the 40 beveled end of the spindle 50 enters its bore to delivery point 28 in the tension-device I8. The fresh bobbin Bis then in position to supply yarn to the winding unit and the end of its strand is led upwardly through the tension~device I8 and 50 spliced to the trailing end on the package being wound. > ’ -'~ ‘ ‘ > . gIt will be observed‘ fromrthe foregoing that the present invention provides a particularly simple yet ei?cient device for the purpose. speci 55. ?ed. The improved supply holder is practically entirely ‘automatic in operation, the operatorhav ing only to press the button to e?ect the dof?ng of the empty bobbin ‘and to then place a fresh bobbin in the chute to cause it to be impaled on 60 the spindle in delivery position. > ' The bobbin-chute is placed in inclined posi tion to enable the operator to quickly and,con— veniently drop the bobbin thereinto. The holder is placed in close‘ relationship with the tension 65 device and iii-elevated position to provide that the end of the strand may be readily threaded through the tension-device without requiring stooping or reaching on the part of the operator. The invention thus provides for a substantial ’saving in .the'time usually required‘ for dof?ngv spent bobbins and supplying fresh ones in. their place. ‘Moreover, less effort and energy is used and the operator’s strength conserved for other duties.
