provements in and Relating to Weft-Replenishing Looms, of which the following is a specification.

My invention relates to looms and comprises a device which, in common looms, enables the operating shuttle to be replaced by a shuttle with a fresh filling, and which, in the manufacture of cross-striped fabrics, for the purpose of introducing a differently colored weft, enables the operating shuttle to be replaced by a shuttle with a filling of this color, without stopping the loom. Applied to change looms the device enables each of the operating shuttles tobe exchanged, according to requirements and in a predetermined manner, for a shuttle with the same or a different weft thread, also without stoppage of the loom; In case the pattern to be Woven comprises more'colors than the number of shuttles which may be placed at the same time in the respective shuttle changing mechanism, the device, owing to the exchangeability of each shuttle for any other desired shuttle without stopping the loom, may also be employed for carpet looms and the like.

According to my saidinvention I arrange on one side of the loom, preferably on the right hand side, two special shuttle boxes or cells in addition to the common shuttle box or cell in the case of loom for plain fabric. In

the case of change looms, I arrange the two now to be removed, in order to catch this shuttle for subsequent removal by hand, whereupon it is replaced, prior to the next pick, by the second special cell holding the fresh shuttle, the placeof the latter cell being then taken by the ordinary cell immediately after the pick. p

In the caseof change looms the arrangement must be such that the two special cells will be placed in line with the shuttle race one after the other just at the moment when the shuttle to be removed is thrown to that side of the loom where the two special cells are situated. For this purpose I provide a special device comprising a card hereinafter named a controlling card. This card controls the change of the shuttles, in lieu of the ordinary change card, in accordance with the successive locations of the special cells,

as soon as the shuttle to be removed is thrown to the side of the special cells. In this case the action upon the shuttle changing device by the controllin card is commonly prevented by separate locking devices corresponding each to one of the operating shuttles and adapted to be released by hand. i With the object of rendering the device available for all cases, that is to say not only where two similar wefts follow each other at the moment the shuttle is exchanged, such as is requisite if the special cells are displaced one immediately after the other, I provide two controlling cards, namely one card for each special cell. Instead of these two cards, use may also be made of a single card with two sets of needles, each set corresponding to a special cell. In this case it is necessary that the two controlling cards or the two sets of needles shall be dependent on each other in their action in such a manner that the cell designed to catch the shuttle to be removed shall first be located in line with the shuttle race. This may be accomplished by a motive power device, such as a spring, be-

ing wound up when the cell for the shuttle to be removed is located in line with the shuttle race,through the intervention of the corresponding controlling card or the corresponding set of needles, the said motive power de vice eflecting the cou ling of the means for locating the cell whici serves for the insertion of the fresh shuttle, the release of the motive power device taking place by the second controlling card or by the second set of needles.

To facilitate the explanation of my invention, Ihave embodied it in a device shown in the accompanying drawings, to the precise construction, however, I do not wish to be understood as limiting myself, it being obvious that changes of construction may be made without departing from the spirit of the invention and the scope of the claims.

In these drawings, Figure 1 is a front elevation of the entire device applied to a loom having a drop shuttle box mechanism of any desired construction on either side. Fig. 2 is a side elevation of the device as seen from the side of the special cells. Fig. 3 is a side elevation of the device as seen from the other side. Fig. 4 is a front elevation of the shuttle-changing mechanism With the special gells. Fig; 5 is a section on the line AB of i 4. on the line 0-D of Fig. 4. Fig. '7 is a view of the chain of controlling cards, detached. Fig. 8 is, on an enlarged scale, and partly in section, a front view of the controlling device. Fig. 9 is a plan-of the-same, and Figs.

--10 and 11 are, on an enlarged scale, and

partly insection, front elevations of the said controlling device in different positions so as to explain its mode of operation. In Figs. 8, 10 and 11 the sides and other parts of the frame are indicated by broken lines in order that the essential features of the invention may be clearly shown.

In the constructional form represented by Way of example the two special cells Z and Z are united with the cells Z Z Z situated on the side from which the loom is driven and appertaining to-a drop shuttle box mechanism arranged on both sides of the loom and having its other cells Z Z Z Z Z arranged on the other side of such loom.

The lifting box B com )rising the cells Z Z Z Z, and the lifting box A comprising the cells Z Z 91 ,71 Z are adapted to be moved independently of each other in the Well known manner by any suitable change mechanism in accordance with the pattern so that one of the cells Z Z Z, Z", Z and one of the cells Z", Z, Z will be located in line with the shuttle race (Figs. 1., 2, 4, Sand 6'). The cells Z ,Z Z Z Z Z, Z, Z are of the ordinary construction, as shown by the cells Z J, Z Z (in Figs. 4 and 5.) The rear Wall 97 is common to all cells Z, Z7, Z Z". The front wallof-each of the; cells Z, Z Z is formed by a tongue or binder 98, 98, 98", eachof which is adapted to be turned in a horizontal plane upon a hinge 99, 99, 99 furnished at oneend in the usual Way. To this turning movement, Which is caused in the Well-known manner by the-entering shuttle, is opposed a spring 100 or 100,-or 100, whereby the-entering shuttle is subjected to a brake action. The tongues or binders 98,, 98, 98', when the corresponding cell is at the height of the shuttle rac'e, act in the Well-known manner upon thefeeler 101 arranged on a transverse shaft 101Wl]l0l'l is supported in hearings on the lathe. At the otherend of the transverse-shaft 101 and rearwardly thereof is secured an arm 101 connected by a rod,

cord or the like, 102, with the catch or pawl 102 of'the tappet 103 for the shuttle driver on the other side of-the loom, the-connection being such-that the catch or pawl Will be released,-if a shuttle is in any one of the cells Z Z Z Whichcell is inline with the shuttle race at the time of picking, the

Fig. 6 is a plan and partial section finger 101 is pushed outwardly, and the rock shaft 101. is rocked, and through connection 100 and the lever 101', the pawl 102 is raised free from the tappet 103, allowing the tappet to revolve without operating the picker stick 104. Through a similar rock shaft and connection, the picking motion on the opposite side of the loom is operated in a similar manner, as is well understood. if however after the passage of a shuttle into one of the cells Z Z or Z an empty cell as Z is located in line with the shuttle race there will be no release of the catch or pawl 102, and the driver 104, according to the pattern, throws a shuttle, meanwhile placed in position through the top of the upper cell Z, or through the outwardlyextending open end of the cell Z see Fig. 6, for this driver, to the side of the special cells Z", 7).

The cell Z is the one wherein the shuttle is put which replaces the shuttle to he removed. The tongue or hinder 08 of this cell Z serves to hold the fresh shuttle until the location of the cell Z" at the shuttle race and the throwing of the shuttle by the driver 104 take place.

The cell Z shown in Fig. 6 in longitudinal section, has its rear Wall, from its inner receiving end, made inclined 0111111 ardly, and extending at an angleto the rear all of the other cells, so that the shuttle entering said cell may be conveniently ren'loved by the Weaver from the outer end thereof. The shuttle cell Z receives the shuttle to be exchanged when located in the shuttle race. In order that the brake action may be applied to the shuttle entering the cell Z", the .rear'u'all of the cell is covered with a stri of leather 106, while the front of the cell is closed by a tongue 107. This tongue is constantly under the action of a spring 105 which for this purpose is arranged. upon a rod 108 connected with the tongue 107 and adapted to bear on the one hand against an adjustablering 109'upon this red, and on the other hand against a guide .1 10 secured-to the shuttle box.

In Fig. 1 the cell Z is shown as in line with the shuttle race To prevent the shuttle which is to be caught in the cell Z" from flying out, I provide outside this cell on the carrier E of the lifting box provided with the guide for the latter a buffer 111, against Which the shuttle is thrown when the brake action is insu'l'l'icient. This buffer 111 is furnished with a soft cushion 11 1 and arranged at the free end of an arm. 1 12 adapted to turn upon a horizontal belt 113 on the box carrier E, so that the projecting arm can yield on receiving a-hlovv from below (F 4 and 6).

For guiding thechangc box B vertically, its vertical sides are provided with ledges 115, 115 adapted to engage with correspond.- ing grooves in vertical guides 116, on the change box carrier. This latter is secured to the leg 117 of the lathe which is pivoted u on a pin 118 fixed below to the frame of the oom (Fig. 1).

The change box B is carried by a push rod 119 guided in an eye 120 on the change box carrier E. To the said push rod is connected, by means of the rod 121, one arm 122 of a bell crank lever 122, 123 arranged to turn upon a horizontal in 124, on the frame of the loom (Figs. 2 an 3). The arm 123 of this bell crank lever is connected by a push rod 125 with an arm 126 fixed upon a transversely oscillating shaft 127 held in bearings at the lower part of the loom. On the left hand side of they loomthe said transversely oscillating shaft 127 carries an arm' 128 coupled by the push' rod 129 with the lever 130 belonging to the shuttle box changing device and serving to place the cells in position. The lever 130 is fitted to turn upon a cross bolt 131 of an arm 132 which can oscillate upon a transverse shaft 133 firmly held upon the frame of the loom. Upon the cross-bolt 131 is moreover provided a twoarmed lever 134, 135, the ends of which are connected through the medium of push rods 136 and 137, see Fig. 3, with bell-crank levers 138 and 139, the other arms 138 and 139 are jointed to push rods 140 and 140. In like manner the lever 130 is connected by a push rod 141 with a bell-crank-lever 142, the

5 and the wheels 159, 160, 161 uponpins fixedl tion cell Z in the shuttle race.

other arm 142 of which is connected with a third push rod 140. Each of the three push rods 140, 140, 140 is jointed by its other end with the crank pin 143 of a toothed wheel or vibrator gear 1.44, 144, 144 which is carried by a lever 145, 145, and 145 respectively. All these vibrator levers turn upon a transverse shaft 146 firmly held in the frame of the loom, and are connected by springs 147 with the push rods 140. At its upper end each vibrator lever 145 is furnished with a triangular head 148 having one of its points directed upward, with which a ratchet lever 149 acts together in such a manner that it stops the vibrator lever in either of its two operative positions. The ratchet lever 149 is adapted to turn upon the pin 151 fixed to the frame of the loom, and has an arm 150 which under the action of a spring 152 is forced against acam 153 ar ranged upon the shaft 154 and adapted to cause the release of the ratchet lever 1.49, in order to release the vibrator lever 145 for the purpose of enabling the latter to be moved from one position to the other.

The vibrator levers oscillate between two toothed drums 155, 156, the former of which is arranged upon the shaft 154, and the latter upon the shaft 157. The shafts 154 and 157 are actuated from the driving shaft 24 of the loom through the agency of toothed wheels 158, 159, 160, 161, 162, 163, the latter two being arranged upon the shafts 154 and 157,

to the frame of the loom, while the wheel 158 is secured to the driving shaft 24.

Each of the aforesaid toothed drums 155, 156 is provided with teeth only upon half the periphery, the division of the teeth corre sponding to that of the wheels 144 on the wheel-carrying levers. The shafts 154 and 157 with the toothed drums 155, 156, as indicated by the arrows I and II, Fig. 3, turn in opposite directions. When the vibrator levers 145, as in Fig. 3, occupy such a position that their wheels 144 come intoengagement with the toothed drum 156, half a revolution will be imparted to them in the direction of the arrow Ill, thereby moving all the push rods 140 to their lowest position. In this case the insertion cell Z is placed in line with the shuttle race, because the drop box B passes to its lowest position. When all the vibrator levers occupy. the other position, wherein the toothed drum 154 comes into gear with the toothed wheels 144 these toothed wheels will have communicated to them half a revolution in the opposite direction to that of the arrow III, and all the push rods 140 are moved to the highest position. Then the drop box B will be'in the highest position and the catch cell Z will be at the height of the shuttle race (Fig. 3).

The movement of the vibrator levers to one or the other operative position, see Fig. 3, takes place by a blade 91 adapted to move constantly to and fro and by lifting wires 90; 90, 90, of which each wheel-carrying lever has one. These lifting wires 90, 90 and 90 are actuated in accordance with the pattern by a roller card 165 which is upon the cylinder 166. The roller card 165 acts upon levers 167, 168, 169 connected by wires 170, 170, 170", see Fig. 1, with the lifting wires 90, 90, 90 and submitted to the action of springs 171 which force the levers against a stop 172 limiting their downward movement. The movement of the cylinder 166 is controlled by a turning hook 173, the rod of which is connected with a bell crank lever 174, 1.75, adapted to turn upon a fixed pin 176 and moved through the medium of an eccentric 178 on the driving shaft of the loom.

In addition to the customary'mode of acting upon the lifting wires 90, 90, 90 I provide according to this invention for the second mode of acting upon the same by the controlling device, whereby only the location of the cells Z and Z in the shuttle race is effected. This latter device will hereinafter be more particularly set forth.

For placing the special cells in position, in addition to the seven lifting hooks P, P", 1, P P P P corresponding to the seven shuttles, I employ another lifting hook P". This lifting hook P is joined to the lever 2 designed for placing the inser- By the shaft 3 mounted in the frame of the mechanism, the lever 2 is firmly connected with a lever 4 which, in opposition to the action of a spring 21, Figs. 1, 8, 9, 10, 11, transmits the operative movement of the lifting hook P, through the draw-rod 5, Figs. 1 and 8, 9, 10, 11, the bell-crank lever 6, 7, adapted to turn upon the pivot 19, the draw-rod. 8, lever 9, shaft 11, lever 12, push-rod 13, Fig. 1, and the lifting-Wire lever 14, 18 adapted to turn upon the fixed bolt 16, to the liftingwire 90 of the drop mechanism, in order to "lift it from the blade 91, whereby the insertion cell Z is placed in line with the shuttle race.

The movement of the blade 1.7 of the controlling device takes place, and also that of the supporting arm 1.9 of the cylinder 31 for the controlling card, from the oscillating shaft 20 supported in the frame of the mechanism. This shaft is actuated by an eccentric 23, Figs. 1 and 3, from the driving shaft 24 of the loom. Upon the oscillating shaft 20 are arms 25 connected by pushrods' 26 With the supporting arm 19 of the cylinder 31, and arms 27 connected with the blade 17 bymeans of push-rods 28. To one of the arms 27 is also connected the rod 29 of the eccentric 23, Fig. 1.

The operative movement of the lifting hooks P P, P, P, P, P, P, is transmitted to the lifting wire by the frame 32 fixed upon an oscillating shaft 30 and having a lower transverse rod 33 on which the lifting hooks P P, P, P, P, P, P, are pivotally mounted. The oscillatory movement of the shaft 39 is transmitted by the arm 34 also fixed upon it, the draw-rod 35, the bell- crank lever 36, 37, adapted to turn upon the pivot 10, the draw-rod 38 and the arm 49 of the two-armed lever 39, 40 on the shaft 11 to the lifting wire 90 in the direction in which the same is hooked to the blade 91, whereby the cell Z for a shuttle to be removed, is placed in position. A spring 41, see Fig. 1, acts upon the bellcrank lever 36 37 in opposition tc-the operative movement of the lifting hooks P, P, P, P, P, P, P on the frame 32. By a fixed stop 22 the movement of the aforesaid frame 32 is limited in the direction of the action of the spring 41, see Fig. 8.

A locking device is provided for each of the lifting hooks P P P, P, P, P, P, this device being adapted. to be released by hand. The devices may for instance consist of stop levers 53, which, being arranged to be turned upon a common fixed shaft 46, take below the respective lifting hooks P P, P, P, P, P, P, and are usually raised by springs 42 to such an extent that the liftling hooks P P, P, P, P, P, P bearing upon them cannot engage with the blade 17.

The action of the springs 42 upon the levers 53 is limited by stops 43 on the indicatingspindles n W, W, it, 1 7. 11", 1V bearing against corresponding ribs 44 on the frame of the mechanism. The indicating spindles 1Y 1V, li, .1 .1, W, W are retatably mounted, and have the disks or engaging surfaces on their front ends, see F 1, and 2, which are furnished with numbers, in this instance, 1., 2, 3, 4, 5, 6, and 7, corresponding to the number of o erative shuttle box cells. Each rotatable spindle W, W, V, TV, W, 1 1 W has secured thereon a crank 45, which. is pivotally connected with a rod or connector N I, 1 N, N, N. N, see Fig. 8, to the stop levers 53.

For locking the stop levers 53 in their released position (at 11', Fig. 19), use is made of a stop bar 46 which by means of arms 47 is fixed upon an oscillating shaft 48 supported in the frame of the mechanism. The free ends of arms 49 firmly connected with the stop levers 53 pass behind the stop bar 46. A stop bar 50 likewise arranged on the arms 47 of the stop bar 46 limits the releasing movement of the stop levers 53. The stop bar 46 is constantly forced to the looking position by a spring 55 attached. to an arm 56 likewise fixedv to the oscillating shaft 48. This device for locking the stop lever 53 in the released position is liberated by the corresponding lifting hook P, P P, P", P, P, P in the operative movement of the. same, a lever arm 93, see Fig. 8, secured upon the oscillatory shaft 30 being adapted to act upon a lever arm 94 which together with the stop bar 46 is fixed upon the oscillatory shaft 48. The stop lever thus left to the action of its spring 42 returns to its operative position and raises the corresponding lifting wire again out of the reach of the blade 17. In the'same manner as the lifting hooks P, P, P, P, P, P, P, the lifting Wire P is usually kept out of ei'igagement with the blade 17. This is effected by a bell-crank lever 51, 71 arranged. to turn upon the shaft 48, and the arm 51 of which is subjected to the action of a draw-spring 52 se cured to the frame of the mechanism. The free end of the arm 51 engages by a pin 96 with a longitudinal slot 54 in the lifting wire. P and usually holds the latter from engagement with the blade 17.

For hooking the lifting wire P to .the blade 17, a turning movement of the bellcrank lever 51, 71 is accordingly required to take place in opposition to the action of the spring 52. This turning movementis imparted to the bell-crank lever 51, 71 by a motive-power device which is put in tension only in. the operative movement of one of the lifting hooks P, P, P", P", P, P, P. This motive power device consists of the spring 55 which on the one hand, as before stated, is attached to the arm 56 upon the oscillatory shaft 48 and on the other hand to a frame 58, arranged to turn upon a shaft 57 fixed in the frame of the mechanism. The lower transverse side of the frame 58, is arranged in front of the blades 17 and usually bears against intermediate levers 60, 61, 62, 63, 64, 65, 66, which have a common fixed stop consisting of a bar 95, see Fig. 8, serving as an abutment in opposition to the action of the spring 55, and which correspond each to a lifting hook P P P P I, P, 1. Theselifting hooks are furnished at their heads with extensions 67 which on the termination of the operative movement of the lifting hooks engage with corresponding notches 68 in the intermediate levers 60, 61, 62, 63, 64, 65, 66, thus causing the respective intermediate levers together with the frames 58, to swingin opposition to the action of the spring 55. In this movement a lifting wire 70 jointed to an upwardly extending arm 69 of the frame 58, engages with the free knife-shaped end of the arm 71 of the bell-crank lever 51, 71 ada ted to turn loosely upon the oscillatory sha t 48.

In order that the frame 58 may not, in the return movement of the lifting hooks P P", P, P P 1 P, at once give way to the action of the spring 55, it is locked in the posi tion to which it has been moved, and wherein the spring 55 is quite under tension, through the agency of a stopping device which may be released by the second controlling card provided for placing the insertion cell Z in line with the shuttle race or, as in the constructional form shown by way of example, by the second row of needles of the controlling card 31. For this purpose the intermediate levers 60, 61, 62, 63, 64 65, 66, 67 have at their lower end a lateral projection 72, and for each of the intermediate levers 60, 61, 62, 63, 64, 65, 66 I provide a stop lever having three arms 73, 74, 75, these levers being arranged to turn upon a common shaft 76. The arm 73 of the stop lever 73, 74 75 forms a hook which se zes and holds the projection 72 of the intermediate lever which has swung outward. To the arm 75 is attached the end of a spring 77, the other end of which is secured to an arm 78 of the corresponding intermediate lever, .forcing the latter to. the position of rest, but the stop lever to the 01perative position. The third arm 74 of t e .tpip lever 73, 74, 75 is connected by a drawro 79 with the corresponding needle levers 80, 81, 82, 83, 84, 85, 86of the second row of needles N N N, N", N N", N, in such a manner that it takes part in the swinging movement of the respective needle lever on the corresponding needle being forced back in the direction of the arrow, Figs. 8, 10, 1 1. By this means the locking device 72, 73 is released, and the spring 55 becomes free. By the turning movement of the oscillatory shaft 48 through the medium of the frame 58, the arm 69 of this frame, the lifting wire 70 and the lever 71, the said spring causes the lifting hook I to be hooked to the blade 17 Like the lifting hooks P P, P, P P P, P, the lifting wire 1? is unhooked automatically at the end of its 0 erative movement. For this purpose the sha 't 3 of the lifting-wire lever 2 carries a third arm 87 having a pin 88 adapted to engage with a slot 89 in a draw-rod 92 jointed to the lifting wire 70. By reason of this slot connection the arm 87 may have an independent upward motion, until at the end of its upward movement it unhooks the lifting wire 7 O, and the lever 71 is turned by the spring 52 so much farther in the direction wherein the lifting wire P is unhooked that the hook of the lifting wire 7 O on falling back cannot take behind the same (Fig. 8).

The controlling cards 31, Figs. 7 and 8, are punched to follow the shuttles, and each card has two indications for each shuttle, and two needles for each shuttle are operated by and under the control of the cards. One set of needles, in this case, the lower set of needles, N etc., engage one end and have under their control a set of angle levers 15, one of which levers is shown in Fig. 8; the opposite end of the lever 15 forms one support for a hook P The hook P has also a second support 53. Both of these sup orts 15 and 53 must be lowered so that the 100k P may dro and be engaged by the reciprocatin bla e 17, as it is moved forward. Said Tilade 17 has a constant reciprocating movement. The hook P when it is allowed to drop and engage the blade 17, is pulled forward, and rocks the lever 32 about its fulcrum, which operates the lever 34, having attached to its end the hook connector 35. The hook connector 35 is connected with mechanism on the box motion end of the loom, which has been hereinbefore fully described, to cause the necessary vibrator levers to be brought into action to cause the lower cell Z to be raised in line with the shuttle race, to receive the shuttle to be removed.

The operation for inserting a new shuttle will be as follows :When the time comes for the insertion of a new shuttle having filling corresponding to the filling in the shuttle removed, the blank space in the card of the pattern chain 31 which corresponds with theshuttle to be inserted, will be operative to push a needle N back, and rock the lever 80 about its fulcrum, causing the attached connector 79 to rock the latch lever 73 about its fulcrum, and release the latch 73 from the hook 72 on the frame 58, which frame will then be moved inwardly by the spring 55, causing the lever 69 to be moved outwardly, and through connector 7 0 to rock the angle lever 71, and cause the lever 71 to lower the hook I in the path of the blade 17. On the outward movement of said blade 17, the hook P is carried forward, rocking the lever 2, shaft 3, lever 4, and connector 5 to the pro er vibrator levers on the box motion end of the loom, to cause the said vibrator levers to lower the box cells, and to bring the spare shuttle cell Z to the line of the race for the insertion of a new shuttle. By the arm 87, fast on the shaft 3, and the draw rod 92, the connector is raised, and the lever 71 unhooked; the spring 52 acts to rock the lever 51, and raise the hook 1 out of the path of the reciproeating blade 17, and it remains in this position until another shuttle is to be removed, and then the operation is repeated. The forward movement of the hook P causes the 5 end of the hook F to engage the V shaped recess 68 in the frame 58 and move outwardly said frame and the projection 72 thereon until said projection 72 engages the notch on the lever 73, see Fig. 8, to lock said frame in its outward position, ready to be released as above described.

It will be observed, that it is necessary for one of the hooks, marked P P P, P, P", P, P to be lowered into the path of the reciprocating blade 17, to cause the first operation, to Wit,-the movement of the cell Z", to receive a shuttle to be removed, to the line of the race-way. As these hooks, P P P P P P P have two supports, it is necessary that both supports should be lowered out of the way of said hooks, before they are dropped on the reciprocating blade 17. One of these supports, 15, as above stated, is under the control of the set of cards 31, which continuously follow the shuttles in their operation, and therefore the said support, corresponding to the shuttle being at the time in operation, will be lowered by the cards each time a shuttle is picked. T he other set of supports 53 are under the control of the hand operated spindles W, W, V W Vi, W therefore when one of the supports 53 is lowered from a hook 1?, etc., by a partial rotation of the spindles W Vi W W", N W, W and the corresponding shuttle and the corresponding indication on the cards 31 comes into position with the needles, marked N N N N N", N, N and lowers the other support 15, corresponding to the support 53, which has been lowered through the turning of a spindle W W WV", W, Y, Vi V the hook P P P P F, P, P", commonly held up by the two supports 53 and 15, will be lowered, and will be allowed to catch the blade 17 on its forward movement.

From the above description it will be plain, that each hook P P P P, P, P P is under the automatic control of a card of the chain 31, and also under the control of one of the spindles W W VV Vi, W Vi to be manually operated.

The advantages of my improvements will be readily appreciated by those skilled in the art. I provide mechanism, which has therein and as a part thereof, a set of indicators, as the spindles N to be operated by hand at the option of the weaver, the operation of which will, through mechanism connected therewith, cause the particular shuttle indicated, which may be any one of the shuttles, the next time said shuttle is called into operation, to run into a special cell from which it can be easily removed by hand, and also to bring into operation a. fresh shuttle which has previously been placed in a special cell for the purpose.

It will be understood that the details of construction of my improvements may be varied if desired, and they may be adapted to be applied to looms of ordinary and well known construction, with. change or drop shuttle boxes, at one, or both ends of the loom.

I have used herein the words manually controlled, in connection with the means for operating the shuttle b xes, but it will be understood that I do not limit myself to a manual or hand. controlled means, as I may sub stitute foot controlled means, with a foot pedal, etc. I intend to cover broadly in the claims, non automatic means, as distinguished from automatic.
