Fig. 15' is a view similar shuttle box at the weft-replenishing side of the loom. -5 is a shuttle of well known const ruction. 718, dated January 18, 1927), there is dis- 5 closed a spinning machine adapted to spin enough coils. of yarn on the upper end of In describing the embodiment of the in vention which is shown in the drawings, reference will bemade to bobbins, since they are the particular kind of weft carrier which is illustrated, but it should be understood thatthe invention may be embodied forms of weft carriers. Y 7 The bobbin 6 herein shown has a butt 7 which is equipped with a plurality of rings 8 to enable it tobe grasped and held bythe usual bobbin-holding jaws (not shown) in the shuttle. The tip 9 of the bobbin is provided with a suitable number of longitudi nal grooves 10 terminating upon the roundjed end of the tip." (See Fig. 14.) Preferably the grooves '10 are formed in the pe-v 'riphery of a metallic sleeve fitting upon the wooden tip of the bobbin. The periphery :of thesleeve is tapered slightly toward its outer end for a purpose to appear hereinafter. -The bobbin carries a supply yarn mass a and a small mass ofyarn Z), the yarn I) being wound upon the grooved portion of the 9 at a substantial distance from the yarn mass'o. The grooves 10 extend beneath the mass 6. Said mass bis connected to the yarn mass at by means of a strand 0.. d is the free end of the yarn.

The reserve supply of bobbins 'is contained I within amagazinewhich may be of any suitable character. Herein is shown a magazine 11 rigidly secured to the supporting framework and adapted to contain. a single column or stack of bobbins, the bobbins resting upon one another. The butt of the lowermost bobbin is' supported by the ledge 12 (Figs. 9

and 10) of a gate 13,,saidgate normally underlying the magazine 11 and beingrigid with an arm 14 which is mounted to swing 1 upon .theaxis 15. in the supporting frame work. The arm 14 Iand the parts carried thereby constituteomeans'for normally clos ing the :lower end oft-he magazine and for transporting bobbinssingly and successively into position to be placed in the shuttle; Rigid with the arm 14 is an arm 16' to which is pivoted a rod 17 that extends slidably through a stud 18 pivoted to a lever 19. The lever 19 is pivote to the loom framework at 20'and'has a roller stud 21that bears against a. cam 22 on a shaft A,contrac-' the machine frame.

Evil

tile spring 24 connected to the lever 19 and anchored to the framework serves to hold the roller stud 21 in contact with thecam 22.

An expansion spring 25 surrounding the lower portion of the rod 17 is interposed between a nut 26 on the lower endof the rod 17 and the stud 18 and serves to keep said stud pressed against a collar 27 on the rod 1'2. The gate 13 is thus yieldingly swung in both directions when weft replen- '28 is normally held in posit-ion to support the tip of the lowermost bobbin by means of a contractile spring 30, said spring holding the linger against a stop 31. W hen the finger 28 is withdrawn, the tip of the'bobbin descend upon a shelf .32 (Figs. 4, 8 and 7) liked to the magazine '11. and underlying the end of the linger 28. At one side of the shelf 32 is a wall 33 to prevent the displacement of the bobbin tip in that direction.

lhe meansyior swinging the finger 28 aside to allow the bobbin tip to drop upon the shelf .32 comprises a shoulder 34 (Fig. 4) on the gate 13 which is arrangedto engage a pin 35 on said finger when the gate is swung into the position shown in Fig. 5.- lhe bobbin tip is prevented from slipping off the shelf 32 by means of a guard plate 36 on the gate 13. The guard plate is shown in Figs. 6 and 8.- By the time the finger 28 has moved out from under the bobbin tip, the ledge 12 has moved out from under the butt of the bobbin, whereupon the bobbin butt drops upon a ledge 37 (Figs. 9 and 10) formed on a bracket 38 fixed in Means is provided to clamp the bobbin so that it shall be supported in proper position after the butt of the bobbin has been carried off the ledge 3? and has been moved off the shelf 32. The said means comprises a jaw 39 (Figs. 6 and 9) fixed to the gate 13 in prolongation of the ledge 12,the face of said jaw being made concave and grooved to it the bobbin butt and'lts r1ngs8. 40 (Figs.

9, 10 and 12) is a jaw fixed to a shaft 41.

carried bythe arm 14. The free end of the jaw 40 is socketed and grooved to correspond with the shape of the. bobbin butt.,. To the shaft 41 is finedv an arm 42 to which. is connected a contractile spring 43'which serves to move the. aw 40 to clamp the bobbin butt between the jaws39 and 40. When there is no bobbin between the

jaws

39 and 40, the action of the spring 43 is limited through contact of the jaw 40 with the, portion 44 (Fig. 10) of the gate 13. As the gate 13 swings in the direction to carry the ledge 12 out from under the lowermost bobbin in the magazine, a pin 45 (F ig. 9) on .the jaw 40 stops against the ledge 37. as indicated in dotted lines in Fig. 9, .thereby causing the jaws of the clamp to be separated to receive the bobbin butt. Asthegate l3swings back to its normal position, the clamp jaws close upon the bobbin butt andgrip the bobbin so as to support it. firmly. The clamp 39-40 constitutes the sole support of the bobbin while the latter being carried away from the magazine.

'Means provided for stripping the yarn niass-b oil the. tip. of the bobbin while the bobbin is being: carried from the shelf 32 and the ledge '37 to the position where it is to await transfer to the shuttle. This .ineans comprises a stripping element which may be of any suitable construction. herein-shown, said element comprises an annular series of-spring hooks 46 14).

The shanks of. said hooks lie within radial slots in a sleeve 47 with the points of said hooks extending toward the axis of the sleeve. The sleeve47 is slidably mounted in a bearing 48 in the gate 13, thesleeve being in axial alinement with abobbin held by the jaws 3S) and 40; The reduced outer end of the sleeve .47 and the shanks of the;

spring hooks 46 are clamped in an arm 49 (Fig. 8) which 1s fixed to oneendof arod 50 that is slidably mounted ina bearing 51 on thegate 13. The other end of the rod 50 is looselypivoted to a lever 52 (Figs. 9 and 10) which is pivotedto the gate 11.3 uponthe axis 53. The lever 52 carries a. roller stud 54.which is held in contact with acam flange 55 (Figs. 5 and 13) on the bracket 38 by means of a. contractile spring 56 (Fig. '10

Said spring is secured at one end to the 13-and at its other end to the rod 50. As the gate 13 swings from the position shown in Fig. 5'to that shown "in Fig. 4, the sleeve 47 is slid onto the tip of the bobbin and withdrawn tl'iere't'rom. When the sleeve 47 is moved toward the bobbin, the spring hooks 46 yield radially outwardly so as to pass onto the bobbin tip an d over the yarn mass 7), the points of most, if not all,

of the hooks entering the grooves 10. W'hen the sleeve 47 is moved away from the bobbin the hooks 46 carry the yarn mass 7) along with them, the strand 0 unwinding fromthe yarn mass a. The devices just described may be termed mcansfor extendingthe end of the thread on the bobbin. The reason for slightly tapering the grooved portion of the bobbin, tip is toprevent the yarn mass 1) from being pushed toward the yarn] mass a,

by the hooks 46.

Then the arm 14 reaches. the position shown in Fig. 4, it is locked in such position by means of a latch 57 (Fig. 4) which is pivoted at 58 to the maclnne framework. said latch having a shoulder 59 which adapted to en age a pin 60on thear'm14.

The latch is yleldingly held'in engagement with the pin 60 by means of a bowed spring '61 which is connected to the machine frame at 62 and to an arm 63 at 64, the arm 63 being rigid with the latch 57. i

The loom may be provided'with any suitable means for initiating the automatic transfer of the bobbin from the clamp 3940 to the shuttle when the running weft becomes exhausted through breakage of the 7 thread or unwinding of the yarn on the bobbin in the shuttle. Since such means iswell "known in the art andniay be'of jvarious types, it has been deemed unnecessary to illustrate any such mechanism herein. Itmay be assumed that the 100111 is provided with the usual starting shaft 8, which is rocked in order to set in motion'the filling or weft-changing mechanism whenever there is a necessity for the replenishment of filling or weft in the shuttle, due eitherto the exhaustion, breakage 'orapproaching exhaustion of the weft in use. The efli'ectofthe movement of this starting shaft is to bring into action a transferrer which transfers a' fresh bobbin from the clamp 39-40 into the shuttle 5 on the lay, at the same time ejecting the spent bobbin from theshuttle- Referring now to Fig. 5, 65 is the transferensaid" transferer consisting of a lever or armwhich is pivotally mounted "upon the axis'66 and is normally held uplifted as shown inFig. 5 by a torsion spring :67 (Fig. 8). The transferer further comprises a rod 68(Fig. 8) fixed to the lever 65 and carryinga fork 69. The end 70 of thelevcr 65 is adapted to engage the butt of the bobbin, while the fork 69 is located in positionto engage the tip of the bobbin. Preferably the fork 69 on the transferer (see Figs. 5 and 8). When the transferer descends. the bobbin is transferred from the position indicated at w in Fig. 9 to the shuttle 5, the spentbobbin being forced from the shuttle by the incoming bobbin. In passing from the clamp 39.4O to the bobbin-holding 'jaws in the shuttle the butt of the bobbin is guided by a stationary member 72 (Figs; 9 and 11),;

the face of said'guide member being grooved for the passage of the rings 8 on the bobbin butt. The bobbin butt is further guided and restrained by a finger 73 (Figs. 9'and 10) whichis pivoted to the gate 13 at 74 and is normally held in contact with the lower side of the clamp jaw 39 by a torsion spring '75.

The end of the finger '7 3 partially underlies the bobbin butt when the bobbin is held in the clamp 3940 and it swings downwardly as the'bobbin isforced out of the clamp.

As the bobbin is transferred to the shuttle, l

the tip of'the bobbin is guided and restrained by" means of a finger'76 (Figs. 5 and 8) which. is pivoted to a stationary support 77 M78. A torsion spring 7 9 normally holds'the finger 76 in the positionshown in Fig. 5, the action of the spring being limited through contact of a stop 80 onthe finger 76 with a stop 81 on thesupport 77.

. The means. for disengaging the latch 57 from the pin 60 comprises an arm 82rigid with said latch'and extending in position to be engaged and moved by the pin 71 when the transferer 65'pushes the new bobbin into the shuttle. Thepin 71 causes the arm 63 'to swingintocontzictwith a stop pin 83 where'it is held'by the action of the bowed spring 61.

position whereit can engage the pin 60 upon the return movement of the arm 14 comprises a link 84 (Figs. 4 and 11) having an elongated opening 85 into which extends '85 The means for restoring the latch to a a pin 86 on the arm. 14. The link 84 also has an elongated opening 87 to receive a pin 88 set in the arm 63. v A contractile spring 89'stretched between the pin 88an'd a lug on the link 84 yieldably connects thearm63 to" the arm' '14. I ,7

Assuming the parts to be'in the position shown in Fig. 4 the operation is as follows:

hen a fresh bobbin isto be substituted for the onein'theshuttle, the transferer 65 is given, a rapid oscillation,whereby the bobbin held by the clamp 39-40 is driven out of said clamp and into the shuttle. Thestrand 0 is later. parted in the usual or any suitable manner. The engagement of the pin 71 with the arm 82 causes the'latch 57 to move into the position shown in Fig. 9. 1 In the rotation of the'cam 22, the arm 14 is moved into the position shown in Fig. 5 and then back to the'normal position illustrated in Fig. 4. As

the arm 14 moves into the position represented in Fig. '5, the ledge 12 moves out from under the butt of the lowermost bobbin in the magazine, whereupon the butt of the bobbin drops onto the ledge 37 (Figs. 9 and 10) and lies between the clamping

jaws

39 and 40. "At the same time, the finger 28 moves out from beneath the tip of the bobbin, which thereupon drops upon the 1 shelf 32-and lies between said finger and the guard plate 36. "normal position, the bobbin. being supported inhorizontalposition by the clamp 39-40.

The arm 14 then "swings back to In the return movementofthe arm'14. the sleeve 47 is slipped over the'tip ofthe bobbin and withdrawn, carrying with it the coil of yarn Z) and unwinding thestrand c from the yarn massia. l I I As the arm 14 swung into the position represented in Fig. 5, the'link 84 and spring ill) said coil from the tip.

89 caused the latch '57 to swing down into the position shown in said figure. In the return movement of the arm 14, the pin slides under the latch and moves into engagement with the shoulder 59 as the bobbin reaches, the position for transfer to the shuttle. Here the bobbin stands with the Strand 0 held. by the hooks 46 until occasion arises for-weft .replenishment.

The waste yarn which collects on the hooks 46 maybe removed at convenient intervals.

The reason for yieldingly connecting the

arms

14 and 63 is to allow the arm 14 to makeits full movement even though the arm 63 should be accidei'itally held against movement. 7
