This invention relates to circular looms, and is concerned more particularly with means for supplying weft in such looms.

The principal object of the invention is to enable circular looms to operate with a continuous weft supply, this being effected according to the invention by replenishing the, or each; shuttle with Weft automatically on weft exhaustion, a spool containing the requisite amount of weft being applied to the shuttle in replacement of an exhausted spool. With advantage, the removal of the exhausted spool from the shuttle and the replenishment thereof take place without cessation of the relative circular motion between the shuttle or shuttles and the warp threads.

In this manner delays for weft replenishment are avoided, and the loom requires much less attention than hitherto has been the case. Because of the weft replenishment taking place automatically, spools of large dimensions are not necessary in order to obtain high efliciency. On the other hand, the spools may be of relatively small size with the consequent advantage that the shuttle dimensions may be reduced also, and therefore a large number of shuttles accommodated round the loom. Therefore a large number of picks may be laid at each revolution, resulting in a high output of the loom.

Conveniently, a shuttle containing an exhausted spool is brought to the outside of the warps for replenishment, means being provided in association with each shuttle for controlling the warp shedding mechanism in its vicinity, on weft exhaustion, so that the warp threads are drawn to one side of the shuttle, and the shuttle can emerge from the warps.

Since such replenishment can be effected with advantage without cessation of the relative circular motion between the shuttle or shuttles and the warps, it is preferred to retain the replenished shuttle outside the warps for one weaving revolution of the loom before reinsertion, the remaining shuttles continuing to weave in the normal manner during such revolution.

When weaving plain fabrics such as hopsacks, taffetas and the like, it is preferred, in order to prevent the formation of a double pick in the fabric, to allow an adjacent shuttle also to emerge from the warps, and to allow this shuttle also to remain outside the warps for a weaving revoluvention may be used for spool replacement on weft breakage, as distinct from weft exhaustion, by the provision of a suitable weft detector, it is generally advisable to bring about stoppage of the loom on such breakage, especially when producing'pick-found cloth. Of course, in the event of weft exhaustion, sufficient weft remains on the spool at detection to complete the pick before the spool is replaced.

Apart from the advantages of substantial continuity of operation and high efliciency resulting from the invention, the lighter and smaller shuttles which may be used are of service in enabling a high rate of weaving to be attained and also rapidly operating weftand warp-stop mechanism to be employed. Thus, when such mechanisms operate to clutch the shuttles and warps together to bring weaving to an end, the lightness of the shuttles enables this to be done in a very short time, thus minimizing the risk of the warp being stretched or broken by the shuttles engaging the jam in the warps resulting from an end breaking and preventing change of shed.

One form of apparatus according to theinvention will now be described in greater detail with reference to the accompanying drawings, in which Figure 1 is a sectional elevation of part of a circular loom of the same general type as that described in U.

Referring to Figures 2 and 11, sheets of warp threads l0 unwinding from warp beams HH proceed downwardly in cylindrical form past lease rods I I to the fabric I2, which is drawn over the edge of a ring I3 by take-up roller I2I disposed at the bottom of the loom.

Between the lease rods I I and the fabric I2 the warp threads are passed through the eyes I4 of hook-like shedding members I5, which pivot about a stationary ring I6 extending round the loom. The members I5 divide the warp threads into two sheets I1, I8 at intervals round the loom for the reception of a number of shuttles I9,

(three shown in Figures 1 and 4), which rotate about the axis of the loom. j'

Each shuttle I9 is driven round the loom by pairs of vane wheels 2I, (Figures 1, 2 and 11), fixed to a shaft 22 which is rotated by gearing 23 driven from a vertical spindle 24. The spindle 24 is encased within an upright bearing 25, and

is provided at its lower extremity with a pinion 26 which engages the teeth of a circular rack'21 outstanding from a stationary ring 28. The bearing 25 is secured to a rotatable ring 29, the motion of which carries the pinion 26 around the stationary rack 21 and rotates the spindle 24.

The vane wheels 2| penetrate the warp sheet I8 and by engaging the flanges of rollers 39 rotatably mounted within the shuttle propel the shuttle forwardly through the warp shed. At the same time, the rotation of the vane wheels allows the threads of the warp sheet I8 to pass into the slots between the vanes and so move freely past the shuttle. The shuttles I9 are supported from behind the warp sheet I1 by a ring 3I, the edge of which forms a raceway for a roller 32 freely rotatable about an axle fixed in each shuttle. The warp sheet I1 thus passes freely between the edge of the ring 3| and the roller 32. As shown in Figure 2, each shedding member I5"is formed with an outstanding arm 34, the extremity of which rides in one of two cam channels 35, 36, (see Figure 1), cut in undulating tracks 31, 38 respectively, which are secured to a rotatable ring 39. The ring 39 is freely supported on brackets 40, which are supported in turn by brackets I49 outstanding from pillars I4I (Figs. 10 and 11), and is rotated about the loom axis at the same rate as the shuttles I9 by a shaft 42 and pinion 43, the pinion 43 engaging a rack 44 formed in the ring 39. The shaft 42 is rotated by a belt pulley I42 secured to the shaft near the lower end thereof (Fig. 11)

The rotation of the ring 39, and consequently of the undulating cam tracks 31, 38, causes'the shedding members I5 to rock about their ivots I6, and to divide the warp threads into sheds in accordance with the positions of the tracks,

in the cam channels 35, 36 in accordance with the pattern to be woven. Thus, in the case of a plain weave, alternate arms will be placed in opposite cam channels, while in the case of a2 and 2 weave, for example, alternate pairs of arms will be placed in opposite cam channels, in a manner which will readily be understood by those skilled in the art. If desired, more than one warp thread may be threaded through each eye I4.

Each shuttle I9 contains a stationary weft spool 46 (Figures 1, 8 and 9) which is fixed in an open-ended case I46, the case being secured in the shuttle by spring clips 41. The weft thread is unwound from the spool 46 by a guide arm 48 arranged to rotate within the case I46 about .the axis of the spool, and proceeds from an eye 49 in the extremity of the guide arm through a passage 56 in the centre of the spool to the rear side of the spool. From the rear side of the spool the weft is led downwardly to a guide hook 5| from which it proceeds to the fell 52 of the fabric I2 preparatory to being beaten-up in the fabric by the succeeding shuttle after "change-over of the warp threads.

On exhaustion of the weft spool 46 the empty spoolis extracted from the shuttle I9 and rolls away from the shuttle down an inclined chute 53 (Figures 1, 5, 6, '1 and 11), a fresh spool from a magazine 54 being inserted in the shuttle in its place. In addition to allowing of purchase by the clips 41, the case I46 containing the spool 46 protects the guide arm 48 from damage during the rolling of the spool down the chute 53.

The initiation of the spool-changing step on exhaustion of the spool is effected by the action of a plunger 56 which is freely housed within a radial bore 51 formed in the barrel 58 of the spool. Weft on the spool holds the plunger 56 in the sunken position shown in Figures 8 and 9, where the lower end of the plunger holds a ball 59 in an annular groove 69 formed in a springurged plunger 6|, which is disposed co-axially with the spool.

As the last few windings of the weft are being taken from the spool, the plunger 56 is freed from restraint and releases the ball 59, with the result that the spring-urged plunger 6I is allowed to move outwardly for a short distance from the spool. A pin I56 penetrating a slot I51 in the plunger 56 limits the movement of the plunger in the barrel 58.

The outer end of the plunger 6| is formed with a button 62, which, on emergence of the plunger from the spool 46, is pushed outwardly to a point in line with one end of a pivoted lever 64, (Figures 1, 3, 4 and 11), which is disposed close to the warp sheet I8. The threads of the warp sheet I8 slide freely over the curved outer face of the button as the shuttle I9 proceeds towards the lever 64.

The function of the lever 64 is to indicate to the warp shedding mechanism the exhaustion of a weft spool so that the shedding mechanism can operate to allow the shuttle containing the exhausted spool to emerge from the warp shed for replenishment.

The warp shedding mechanism is controlled at a point immediately in advance of each shuttle by a lever 61 (Figures 3 and 4) which is pivoted at 68 on the cam ring 39, and is connected by a link 69 and a spring-urged crank 19 to one end of a spindle H which penetrates the cam ring 39 at a point in advance of the shuttle I9. Secured to the other end of the spindle II is a track switch 13 which, on rotation of the spindle, operates to change the contour of the cam channel 35 by diverting the cam channel to a new channel I13, with the result that the extremities of the arms 34 of the shedding members I5 are directed to the new channel I13 and-push the threads of the warp sheet I8 to the rear of the shuttle I9,

in line with the sheet I I so as to allow the shuttle to emerge from the warp threads.

The lever 91 is restrained normally against the pull of the spring-urged crank I by a springurged latch 63 which is pivoted at 66 on the ring 39 and is formed with an arm I93 which projects from the ring 39 to a point closely adjacent to one end of the pivoted lever 64.

On exhaustion of the weft in a spool, the expelled button 92 is carried by the shuttle against the lever 64 which rocks and strikes the projecting arm I83 of the latch 93. The latch is thus rotated about its pivot 68 and releases the lever 8'? to rotate about its pivot 68 under the infiuence of the spring-urged crank III, with the resuit that the track-switch I3 is operated and the threads of thewarp sheet I8 commence to pass' to the rear of the shuttle l9.

The continued rotation of the ring 39 has, by this time, brought outwardly projecting teeth I2 of the lever 61 into engagement with a pin-wheel 15, which is fixed to a rotatable shaft 16 mounted on a stationary supporting bracket 11, (see Figures 3 and 4) to cause the pin-wheel 15 and shaft 16 to make half a revolution.

A crank I8, fixed to the bottom of the shaft I6 is connected by a link I9, spring BI and collars 82 to a double bell-crank lever 83 (Figures 5, 6, '7 and ll) which is pivoted about a fixed point 84 on a support I 84. On rotation of the crank 18 by the pin-wheel E the lever 83 is caused to rock in a clockwise direction about its pivot 84, and in so doing releases from a restraining catch 85 a spool extractor member 88 which is pushed towards the shuttle I9 by a spring-urged cranked lever 81, and guided by a link 88.

The extremity of the shuttle extractor member is formed with a claw 89 into the grip of which the expelled button 62 is brought by the con-.

tinued motion of the shuttle I9. The exhausted spool 49 is thus secured by the extractor 86.

The continued forward motion of the shuttle l9 in its circular path round the loom causes the shuttle to draw away from the extractor 86, and since the claw 89 still retains its grip on the button 62, the spool 46 is withdrawn sideways from the clips 47. A stop 9I positionedin the shuttle 9 at the rear of the spool 46 pushes the spool forwardly, and in doing so, pushes the extractor 86 backwardly, causing the cranked lever 81 to rock in a clockwise direction. The link 88, however, prevents direct backward motion of the extractor and causes the clawed extremity to follow a sweeping path towards the chute 53 where the extractor 86 is brought into contact with a pin II5 upstanding from the support I84. The stop 9| continues to push the spool 48 (Figure 7) which is then expelled from the claw 89 of the extractor, and rolls down the chute 53 to a suitable receiver (not shown).

The clockwise rotation of the lever 81 under the influence of the extractor 86 pushes forwardly a spool injector member 92 which normally rests with its operative extremity near the discharge opening of the magazine 54. The operative extremity of the spool injector member 92 spool 99 in a casing 95 runs out of the magazine and engages its button 62 inthe claw 93 of the injector. The injector 92 is slotted at E53 and is guided by a pin I54 which penetrates the slot. On being pushed forwardly again by the backward motion of the extractor 86 under the influence of the stop 9I, the injector 92 places the fresh spool 99 directly in the path of the approaching shuttle I9, the continued motion of which causes the casing 95 to be engaged by the clips 47 which carry the spool out of the claw 93 and away from the injector 92.

The backward motion of the extractor 85 under the influence of the stop 9! causes the extractor again to be engaged by the catch 85 on the lever 83, with its operative extremity out of the line of the warps, ready for further operation, as the occasion demands. A stop I89 on the support I84 prevents the extractor 89 moving too near to the shuttle i9, and an adjustable stop I92 on the lever 83 allows the inoperative positions of the extractor and the injector 92 to be adjusted.

The weft ends from the several-reserve spools in the magazine 54 are drawn through an opening 55 in the magazine to an anchoring point 65 P to which they are secured. Thus, with the newly inserted spool 98, the end IGI of the weft extending therefrom is secured at 65, and by reason of the continued motion of the shuttle I9, the weft is unwound from the new spool 99 and lies against the warp threads. Weft from the new spool 99 is not inserted in the warps until the shuttle 59 has made one revolution round the loom, as will be explained later.

Since the warp shed-ding is effected according to the plain system, that is to Say, all the warp threads lying to one side of one shuttle are changed-over to the other side of the succeeding shuttle, continuously round the loom as in the manufacture of hopsack and taffeta fabrics,

it will be understood that the warp threads 00- tle I9) will be exposed by what, in effect, will be an unshedding operation, and as a consequence weft from shuttle 91 will be laid on top of the weft l=aid-by shuttle I 91, and a double pick will be formed in the fabric. V

In order to prevent this, the warp threads I0 are passed to the rear side ofthe succeeding shuttle 91 also, weft from the shuttle being floated round the loom outside the warps. Thus, on the exhaustion of the spool of any shuttle and consequent emerging of the shuttle from the warps for replenishment, the succeeding shuttle also is caused to emerge from the warps.

In this connection a cam 89, (Figs. 3 and 4), secured to the shaft I3 beneath the pin-wheel I5 bears against one end of a'pivoted, spring-urged rocking lever 98 on rotation of the pin-wheel by the toothed lever 67 controlling the shedding for the shuttle I9. The other end of the rocking lever 98 is arranged closely adjacent to the upper extremity of the lever 64 and pushes the lever inwardly again, so causing the lever to strike the latch 63 controlling the shedding mechanism for the shuttle 91, which latch has been brought near the lever 64 by the continued rotation of the cam ring 39. The striking of the lever 64 by the rocking lever 98 is shown in Fig. 4.

This latch 63 releases its leverfil which rotates about its pivot 68 and, through a link 99 and a lever 51.

spring-urged crank I (see Fig. 3) rotates. a spindle I02 in the cam ring 39. A track-switch T4. (Fig. 1) is fixed to the inner end of the spin dle I92, and, in the manner explained with reference to the spindle II and switch 13 diverts the channel 36 to a new channel I14 with the result that the threads of the warp sheet I8 are pushed to the back of the shuttle 9'! also. Both the replenished shuttle I9 and the succeeding shuttle 91 then proceed idly round the loom the whole warp sheet. I9 passing behind the two shuttles.

In the meantime, the teeth I2 of the second lever 61 have been brought by the rotation of the ring 39 into engagement with the pin-wheel I and have rotated the wheel through another half revolution, bringing the wheel into, the position it occupied before its engagement by the first The shaft I6 and crank 18 are thus rotated again, the rotation occurring just as the spool extractor'86 has engaged the button 62 of the exhausted shuttle, so that the catch 85 of the lever 83 is brought into position again for engaging the extractor 86.

The cam 80- on the shaft 16 is also rotated with the shaft and enables the rocking lever 98 to release the pivoted lever 69 which is then allowed to. hang freely with its end clear of the path of the arms I63 of the catches 63.

The continued forward motion in its circular path of the replenished shuttle I9 draws across the fell 52 of the fabric I2, the length of weft 'IOI (Fig. 1), which extends from the spool 90 directly to the anchorage 65 prior to being depressed to the fell of the fabric.

At this point in the operation of the loom, the teeth I2 of the lever 61 controlling the shedding mechanism for the shuttle I9 are brought against the pins of a second pinwheel I93 fixed to a shaft I04 which is rotatably mounted in the support I1. On rotation of the wheel I03, a crank I05 secured to the lower extremity of the shaft. I04.

'is caused to operate an articulated push rod I06,

the outer extremity I01 of which is pushed partly across the path of the replenished shuttle I9 (Figs. 1, 4 and 11)..

Secured to each shuttle. I9 in the. path of the rod I9! is a cranked catch I08. which pivots about a point I09 and is connected by a link IIO to a pivoted thread guide arm II I. On engagement 'of the catch I08 by the rod I01 the motion of the shuttle causes the catch to be rotated about its pivot I09 with the result that the. guide arm I II is swung upwardly to the position shown on the left of Fig. 1, where the hook 5|, which is formed at the end of the arm III, engages the weft length Ifll extending from the new spool 90 directly to the anchorage 65. The catch, I08. quick- 1y passes the rod I01 and drops to its normal position under the influence of a spring H4 so that the guide arm III descends to the vertical position shown in the middle of Fig. 1',. with the weft thread IOI engaged within the. hook. The weft thread thus proceeds from the new spool 99' to; the fell 52 of the fabric I2 where it is laid bythe shuttle I9 as it proceeds round, the loom. On passage of thelever 61 controlling the shedding mechanism for the shuttle 9-? past the pinwheel I03 the crank I05 is again rotated and draws the extremity I01 of the push rod out of the path of the shuttles.

After the replenished shuttle I9 has. completed. one revolution round the loom, it is admitted into the warp threads at the point from which it. emerged, so that it can continue to weave at precisely thesame point at which it ceased.

On completion of a revolution round the loom, a pin I I2 depending from the lever 61 controlling the shedding. mechanism for the shuttle I9 is brought against an inclined cam face I13 formed at the end of the support 'I'I (Fig. 4) with the result that the lever is rotated in an anti-clockwise direction about its pivot 68 and the track switch 13 is re-set in its original position, the lever 6T being engaged and held by its catch 63. Warpshedding for the: shuttle I9 thus starts again in the normal manner.

The shuttle 9'! is similarly admitted into the warps again, a pin I I2 on the lever 61 controlling the shedding mechanism for that shuttle being similarly engaged by the cam face. II3 to re-set the track switch 14.

If necessary, to preserve the even spacing of the weft during the revolution of the loom immediately following replenishment of a shuttle, in spite of the omission of the two weft threads, thet-ake-up mechanism of the loom maybe caused, by any suitable means (not shown), to take up a slightly reduced amount of fabricv during such revolution.

At the point beneath which the shuttles enter and leave the warp threads: is fixed a toothed weft cutter II6 (see Figs. 2 and 7) arranged so as to operate close to the surface of the: fabric. Thecutter H6 is actuated by a rotatable spindle II'I having an upstanding extremity I I8 which is engaged by a catch II9' projecting from the re.- tating ring 29 (see Fig. 2). The cutter H6 is. thus caused to sever the weft length extending from the fabric to the ejected spool 46, together with the anchored weft I01 and the floated weft ends left on the surface of the warp threads, which ends proceed from, and re-enter the warps at the same point.

Breakage and jamming of the warp threads I0 is detected by a feeler I (Fig. 1) which is pivoted at the top of each shuttle and projects forwardly from the lower portionof the shuttle. On encountering a jam of the warp threads, the feeler 120 is pushed backwardly towards the. shuttle, and actuates a push-rod I2I which operates to bring to an end relative motion between the shuttles and the warps conveniently in the manner explained in detail-in U. S. application S. No. 655,561 filed 7th February, 1933.

In a circular loom, a plurality of shuttles between which and the warp threads there is relative circular motion with respect to the loom axis, a weft spool in each shuttle, means operable on substantial exhaustion of the weft in any spool to manipulate the warp threads in the vicinity of the shuttle containing such spool so as to stop weaving by said shuttle during a predetermined interval without interrupting said relative circular motion between said shuttles 'and said warp threads, means to extract the exhausted spool from its shuttle, and means to replenish said shuttle with a fresh spool during said interval.

16. In a circular loom, a plurality of shuttles adapted to lay weft in the fabric, weft replenishing means, warp-shedding means, control means for said warp-shedding means in association with each shuttle, means disposed in each shuttle and controlled by the weft therein adapt- 10 ed on weft exhaustion to actuate the corresponding shed control, means to permit said shuttle to emerge from the warp shed, means actuated by said weft-controlled means for operating said weft replenishing means on emerl5 gence of said exhausted shuttle from the warp shed, and means to render the warp-shedding means operative after replenishment of the shuttle and allow the replenished shuttle to re enter the warp shed.

17. In a circular loom, a plurality of shuttles between which and the warps there is relative circular motion, said shuttles being adapted to lay weft in. the fabric, weft replenishing means, warp shedding means adapted to divide the warp threads into two sheets for the reception between them of a shuttle and to change over said sheets for each consecutive shuttle, control means for said warp-shedding means in association with each shuttle and adapted on weft exhaustion to actuate the corresponding warp shedding means so as to bring to an end warp shedding at that shuttle to allow said shuttle to emerge from the warp shed, means to actuate said weft replenishing means on emergence of said exhausted shuttle from the warp shed, means to bring to an end warp shedding at a shuttle adjacent the exhausted shuttle to cause said shuttle also to emerge from the warps, so preventing the laying of weft in the fabric by said shuttle, and means to return the warp shed controlling means of both shuttles into operation after the replenishment of the exhausted shuttle.

18. Circular loom according to claim 17, comprising means operable after one revolution of the loom to actuate the means by which the warp-shed controlling means of the exhausted shuttle and the adjacent shuttle are returned '0 into operation.
