15 Claims. (Cl. 139-232) This invention relates to improvements in bobbin selectors for weft replenishing looms and it is the general object of the invention to permit a plurality of stacks of bobbins to supply weft for the replenishment of a single shuttle.

The usual multicolor weft replenishing loom employs a magazine having several vertical stacks of reserve bobbins each assigned to one of the shuttles of the loom. The selecting is accomplished by means of a rocking and sliding member or selector under control of the box motion or some part moving therewith for the purpose of registering the selector with the stack corresponding to the active shuttle. When coarse weft is being woven, such as the roving in ourtains, the stack supplied with the roving becomes rapidly exhausted and requires frequent renewal on the part of the attendant.

To meet this condition it has been proposed heretofore to assign two or more stacks to the same type of weft, but under these conditions it is necessary to alter the control which would otherwise be exercised over the selector by the box motion and also provide for uniform de pletion of the stacks. It is an important object of my present invention to provide means by which bobbins are drawn alternately from a pair of stacks for successive replenishments of the coarse weft shuttle when the latter is placed in action by the box motion. In order to draw bobbins alternately from said pair of stacks I use a stop mechanism movable into and out of stopaing position relatively to the aforesaid selecemploys four stacks of reserve bobbins one of which will be provided with flne weft and the others of which will have coarse weft when certain types of curtains are being woven. The fine weft provides the open mesh ground weave while 4 vention to provide control means for the selector which will permit the use of two stacks of predominant roving, one stack for the fine ground weft, and the last stack for a less frequently usedroving.

In order to locate the selector correctly with 60 respecttotheseveralstacksofthe magazine it a necessary to modify the usual connections betweenitandtheboxmotionand itisafurthe:- object of the invention to construct these connections in such a way that the selector will 55 The usual multicolor weft replenishing loom as be moved to three different positions by a box motion operating with three different shuttles. but wherein the selector can occupy a fourth position without requiring an additional indication from the shuttle box. In this feature of my invention the connections operate upon a single shift of the shuttle boxes to move the selector from the first of the aforesaid positions where it registers with the first stack into resistry with the third stack for the second of the aforesaid positions, a two-box shift moves the selector into registry with the rear stack in the third of its positions, and a lost motion connection absorbs the excess motion of the shuttle box indication, while the fourth of the aforesaid positions is obtained by the previously mentioned stop mechanism.

With these and other objects in view which will appear as the description proceeds. my invention resides in the combination and arrangement of parts hereinafter described and set forth.

In the accompanying drawings; wherein a convenient embodiment of my invention is set forth,

Fig. l is a side elevation of a multicolor weft replenishing mechanism having my invention applied thereto.

Fig. 2 is a vertical section on line 2-2 of Fix. 1.

Figs. 3 and 4 are enlarged side elevations of the front pair of vertical bobbin releasers made according to my present invention and shown in different positions,

Fig. 7 is a fragmentary top plan view taken in the direction of arrow 1, Fig. 2.

The invention is used in connection with a loom having shifting shuttle boxes at one side and a single shuttle box and multicolor weft replenishing mechanism at the opposite side. In the present instance I show three shuttle boxes in, ii and i2 mounted on the usual box lifter rod it which is under control of the pattern and shuttle box operating mechanisms not shown. Any one of these shuttle boxes can be moved to active position with respect to the lay it and picking mechanism not shown of a usual type will pick the shuttle in the active box from the left to the right hand side of the loom on one pick and then pick the shuttle back to the shut tie boxes on the next pick. The boxes can then either shift to render another shuttle active or they can remain stationary to permit the weaving of two more picks by the first shuttle. In Fig. 5 I have shown the top and bottom shuttles at R and R for carrying two diflerent kinds of roving, while the middle shuttle G is for the fine ground weft.

The magazine at the right hand side of the loom comprises a frame 20 having an inside plate 2| with a supporting foot 22 on which is mounted a transferrer stud 23. The transferrer arm 24 is provided with the usual transferrer latch 25 liftable by rod 28 into position for engagement with th lay carried transfer bunter 21. Ordinarily the latch is in the down position shown in Fig. 1 and the transferrer arm will be in its idle raised position as the lay l5 moves toward front center position. When a transfer is to occur the rod 26 is depressed while the lay is in a rearward position so that the subsequent advance movement of the lay will cause descent of the transferrer arm by engagement of the latch by the bunter.

Mounted for vertical movement on the plate ii are slides 80, SI, 22 and 33 each cooperating at the lower end thereof with a cradle 34 which controls the discharge of the lowest bobbin in the associated stack of bobbins. It is to be understood that there will be a stack for each of the vertical slides 30 to 23 and that rocking of any cradle advances a bobbin from the corresponding stack to transferfposition under the transfer-reiarm. Each vertical slide has a wedge 85 cooperating with a spring plunger 36 to complete the movement of the slide to either of its extreme positions. A dog 31 is pivoted at 28 to each slide and is acted upon by a small compression spring 38 to move to the left from the position shown in Fig. 2 when the slide is raised. Ordinarily when the slide is down the dog engages a part of the magazine plate 2i and is held in the retracted position of Fig. 2 out of the path of a shelf 40 formed as part of a casting 4i secured to a horizontal rock shaft 42 iournaled on the plate 2|. This shaft carries a forward arm 43 connected to the previously described rod 28 and also has a rear arm 44 connected to a depending rod 45 attached to a thread cutter and shuttle feeler 45. The dogs 31 have their lower ends below the shelf 40 when the latter is in its normal raised position and the slides are down, but as the slides rise the dogs swing outwardly and over the shelf in position to lower the latter when the slides are depressed.

The selector and slide actuator 60 is mounted on a horizontal rod ll slidably mounted on the plate 21 and has front and rear operating fingers 52 and 53, respectively. Each vertical slide has an upper lug II by means of which the slide can be raised by one or another of the selector ilngers preparatory to a replenishing operation, and each slide also has a bottom lug 58 by means of which the selector can depress a previously raised slide to discharge a bobbin from the corresponding stack 'and engage the shelf II to rock the shaft 42 in a clockwise direction as viewed in Fig. 2 for the purpose of depressing rod 2! and raising rod 4!.

The rear end of rod Ii has secured thereto a collar 80 provided with a groove Bl to receive the upper end of a positioning lever 82 pivoted at a on a fixed part of the magazine frame. A light tension spring il acts to move the lever ill in a clockwise direction as seen in Fig. 1 for the purpose of urging the selector toward its foremost position.

As shown in Fig. l the loom is provide with weft detecting mechanism D for the purpose of lifting the fingers 52 and 53 from their normal position when exhaustion of weft is indicated. The detector mechanism includes a rod 85 connected to an arm 66 operatively related to the selector and attached at its lower end to a vertically moving lever 61 floating on a rod head 68 which is caused normally by rod 69 to rise and fall in a two pick cycle during loom operation. The rising motion of rod I59 causes rod 65 to transmit a force to the selector to give the downward movement of fingers 52 and 53 to lower any previously raised slide registering with one of the fingers while the shuttle is on the drop box end of the loom. On non-indicating beats of the loom when the shuttle is at the magazine end the lever 61 is moved downwardly without interruption, but when the detector indicates weft exhaustion the lever is prevented from having its normal downward movement and acts to depress rod 65 and thereby rock the selector ill in such direction as to raise its fingers I2 and 53 and lift whichever vertical slide registers with the fingers.

The matter thus far described is of usual construction and operates in an ordinary manner and is set forth more particularly in the following patents: 1,030,748; 1,510,765 and 1,912,523.

In carrying my present invention into effect I modify the vertical slides 38 and Si by adding thereto additional dogs for cooperation with an oscillating lever which controls a stop or positioner for the selector, and I also modify the usual connection between the drop boxes and the lever 82.

Projecting upwardly from slide 30 is an arm Ill having a head Ii and a dog 12 pivoted thereto as at I2. A spring ll similar to spring 89 is interposed between the head II and the dog and tends normally to move the lower end 15 of the dog to the right as viewed in Fig. 1. In similar manner the slide M is provided with an arm 80 having a dog 8| similar to dog I2 and tending to move to the left as viewed in Fig. 1. When both of these slides are down the dogs 12 and II engage the shelf 82 of a plate 83 secured in vertically adjusted position on a second plate 84 by screws 85, the springs ll being compressed under these conditions. When either of the slides 20 or 3i rises its spring 14 rocks the corresponding dog from normal idle to projected working position.

Setting lever 86 swings about a stud 81 mounted on the plate Ii secured to the magazine plate 2! and located preferably midway between the slides 30 and ii. The front and rear ends of lever 86 are provided with studs iii and 89, respectively, which project toward the plate 2i sufficiently to be in the path of their respective dogs 12 or Bi when the latter are projected to their working position.

A stop 90 which may be in the form of a sheet metal plate is pivoted as at Bl to magazine plate .2! and extends outwardly from the latter to overhang the selector ill. The upper end of a link 92 is pivoted as at 93 to lever 86 while the lower end of the link is hooked as at 95 and passes through a hole 96 in the stop 90. The latter pivots freely about its axis 9| and has an outer end .1 which can be held above the selector ill or fall in front of it to stop forward movement thereof under action of spring 64.

The connections between the shifting shuttle boxes and the lever 02 are shown In Figs. 5 and 6 and include a lever I mounted on the stud 63 in front of lever 52 as viewed, for instance, in Fig. 6. The upper end of lever I00 has a lug I 0| extending laterally therefrom into the plane of movement of lever 02 so that it lies in front of the latter lever when the parts are viewed from the right or the front of the loom. A light spring I02 has the lower end thereof connected to lever I00 and has its end fixed at I 03 with respect to the magazine frame. Lever I00 is attached to the drop boxes by aconnector designated generally at I which includes a relatively strong spring tension I05 which is stronger than the combined strengths of springs 04 and I02. From the lower end of spring 105 the connector I05 extends downwardly around sheaves I01 to the opposite side of the loom and then upwardly to be attached to the drop boxes. The magazine plate 2| carries a stop IIO for engagement with the lever 02 as will be described hereinafter. In Figs. 5 and 6 I have shown connector I05 attached directly to the drop boxes, but it is to be understood that I am not limited to this means of causing the connector I05 to move in unison with the shifting of the boxes.

In operation, the shuttle boxes R, G, R shift according to any predetermined sequence, and in their shiftings operate through the mechanism shown in Fig. 5 to slide the selector back and forth. When the boxes are down so that shuttle R is active, spring I02 rocks lever I00 to its right hand full line position shown in Fig. 5, and spring 50 tends to move lever 62 to the right or full line position shown in Fig. 5 into engagement with lug l0i, with finger 52 in register with'slide 30.

When the boxes rise to place shuttle G in active position the downward pull of connector 35 exerted through spring I06 moves the lever 300 to the left or rearwardly to the dotted line position shown in Fig. 5, and the lug IOI at the same time causes lever 52 to move rearwardly to place finger 53 in register with slide 32. The proportions of the levers with respect to the amount of movement of the shuttle boxes is such that a one-space box shift will cause movement of the selector from registry with slide member to register with slide member 32. When in the dotted position shown in Fig. 5 lever 52 is spaced forwardly from the stop H0.

When the boxes rise to their highest position to place shuttle R in active position the connector I05 has a further downward movement to rock lever I00 in a left hand direction and cause lug I0l to move lever 52 against stop H0. This last operation occurs during an intermediate stage in the shifting of the shuttle boxes which places shuttle R in active position, and when finger 53 is in register with slide 30. Continued rising movement of the shuttle boxes causes the heavy spring I06 to expand because of the engagement of lever 52 with stop H0, hence finger 53 remains in register with slide 33. Since a onespace shift of the shuttle boxes produces a movement corresponding to a two-space shift of the selector with respect to the vertical slides, it is necessary to provide some means for absorbing the excess movement of the shuttle boxes when the latter are moving to place shuttle R in active position after finger 53 has moved into registry with the rearmost vertical slide.

In the previous description of operation it is assumed that the stop 90 is raised with the lever 00 in the full line position shown in Fig. 4,

hence the stop does not interfere with the selector and the latter can assume its front position in register with slide 50. When a transfer is initiated the selector 50 will have a rocking movement to lift whichever of the vertical slides 30 to 33 registers with it. Assuming that lever 80 and stop 00 are in the position of Fig. 4 and that shuttle R is active and exhausted and finger 52 registers with slide 00, the latter will be raised when the shuttle R is at the magazine end of the loom and the dog II will move from the full to the dotted line position of Fig. 4, the dependill ing end 15 of the dog overhangingstud 88.

When slide 30 is subsequently depressed to eflect release of a bobbin from the front stack, the descending dog I2 will engage the stud B0, and rock lever 00 to the full line position shown in Fig. 3, and as slide 30 assumes its lowest position the dog I2 will be reset by the shelf 02 of plate 03. This resetting of the slide 30 to its normal low position occurs while shuttle R is at the magazine end of the loom and box I0 is in active position, and the shifting of lever permits the end 01 of stop 50 to fall on the hub 5 of the selector 50.

Since the shuttle R carries roving or decorative coarse weft it is called only occasionally, and upon arrival at the left hand side of the loom the boxes will shift upwardly one space to place shuttle G in active position for the weaving of ground mesh and there will be an accompanying shifting of the selector 50 rearwardly to the dotted line position shown in Fig. 5 with finger 53 registering with slide 02 which corresponds to the third stack of bobbins carrying the fine ground weft. If this shuttle is depleted it will be replenished in the usual manner.

During rearward movement of selector 50, the end 91 of stop will fall from the dotted to the full line position shown in Fig. 6 and in alignment with the hub H5 of the selector. If after the required amount of ground mesh fabric is woven, shuttle B should again become active, the boxes will descend and spring I02 will move the lever I00 to the full line position in Fig. 5, and spring 04 will attempt to turn the selector to its forward position, but stop end 01 will prevent full forward movement of selector 50 and will hold finger 52 in register with vertical slide 3i. Lug IIlI at this time is spaced forwardly from lever 62.

Shifting of the selector due to alternate activity of shuttles R and G will go on until shuttle R is again depleted, whereupon slide 3| will be raised by finger 52 due to the fact that the stop 90 is holding the selector in the position shown in full lines in Fig. 6 and dog BI will spring out to working position as shown in Fig. 3. Subsequent descent of slide 3| will cause dog 0| to engage the stud 00 and rock'the lever 86 to the dotted line position shown in Fig. 3, which corresponds to its position shown in Fig. 4. The link 92 will be raised at this time to lift the stop 90 out of the path of the selector hub I I5. This upward movement of the link 92 occurs toward the end of the rocking of finger 52 which depresses slide 3i and 7 any endwise movement forwardly of the selector 52 under the action of spring 54 will occur after the slide 3| has been moved downwardly far enough to permit the spring plunger 36 and wedge 35 to complete resetting. The front slides 30 and SI are now back in their starting position, one bobbin having been drawn from each of the front pair of stacks for the replenishment of shuttle R. and subsequent replenishments of this same shuttle will draw bobbins alternately from these stacks.

While I have shown shuttle R my invention is not necessarily limited to its use, but when employed its replenishment will occur in the usual manner, the connections shown in Figs. 5 and 6, particularly the spring Hi6 and the stop ili'l, cooperating to align the finger 53 with the rear slide 33 as already described.

It is to be understood that the present invention is useful more particularly in those types of looms which weave a fabric having coarse and fine weft and in which the coarse weft is consumed much more rapidly than the fine weft, and also in which the characters of weft alternate in such a way that either shuttle G or R will always be active after a short period of activity of a shuttle R. The selector 50 will therefore be moved rearwardly from its foremost position at frequent intervals to permit the stop 90 to fall to its operative position with respect to the hub Ili between successive calls for replenishment of shuttle R.

It will be apparent that when stop 90 is raised its weight tends to turn lever 86 in a clockwise direction as viewed in Figs. 2 and 4. In order to hold the lever and stop with the latter raised, there is provided a small friction spring 94 on stud 81 held against lever 86 by head 11 of the stud and forcing the lever into frictional engagement with the plate 16. Nut it affords adjustment for spring pressure. This spring acts to hold the lever in either position to which it is moved and yields to permit rocking of the lever by dogs 12 and ti.

From the foregoing it will be seen that I have provided simple means by which a shuttle carrying coarse weft can be replenished with bob bins drawn alternately from two stacks of a magazine. It will also be seen that when the selector controls permit it to be moved forwardly from registry with slide 32 it can assume either of two positions depending upon the location of the stop Ill. The lever 86 is mounted on a plate which can be constructed as a small unit or subassembiy to be applied to the usual type of magazine. It will also be noted that the forward pair of slides are modified by upper extensions which carry the additional dogs 12 and 8| for operation of the lever 8!.

In a weft replenishing loom having a pair of stacks of reserve bobbins and a bobbin relesser for each stack, a selector registerable with said releasers. one at a time, and having a movement upon initiation of a replenishing operation to move the releaser registered therewith in one direction and having a subsequent movement to move said releaser in the opposite direction, a

aseases controller for said selector movable to determine with which releaser said selector shall register. and an actuator on each releaser moving to position for cooperation with the controller when the corresponding releaser has said movement in one direction and cooperating with said controller to change the position of the latter when the releaser moves in said opposite direction.

15. In a weft replenishing loom having a pair of stacks of reserve bobbins and a. bobbin releaser for each stack and wherein a selector registerable with either releaser gives the releaser registered therewith a movement in one direction when the active shuttle indicates exhaustion and is at the magazine end of the loom and gives the releaser a return movement in the opposite direction incident to return of the depleted shuttle to the magazine end of the loom on a later pick. a controller for the selector movable to determine with which releaser the selector shall register, and means operated by the return movement of either releaser to change the position of the controller and cause the latter to effect registry of the selector with the other releaser.
