larly to provide a fillingr` detector meehanism harinle` ,a part or member to engage. the filliupl in the shuttle. and means to operate said parl or member through the medium of air pressure.

ln making my improvements in filling,r deteetor mechanism. l preferabl)v have a mow able party or member, attached to or eonneeted with a pueumatie air device or bellows. whieh is preferal'ily located on'the end ofl the. lay at the magazine endof` the loom. and at the reai'of the stationary shuttle box at.

vsaid end of the lay. 'Said movable part is adapted to enter through au openiim in the rear wall of the shuttle box` and through an opening'in the shuttle. every time that the aetiye shuttle. enters the stationary shuttle box. and on the substantial or praetieal exhaustion of' the filling in the lqhuttle. opel'- atesl meeh'anism eonneeted with the we'f't. replenishing meehanism, to cause a` 'fresh filling' earrier or bobbin to be supplied to the lshuttle. in plaee of the substantially exhausted bobbin. in the usual and well known way.

.mentsl applied thereto.

teetor or ,leele'r is connected, is located atthe rear wall'of' the stationary shuttle box, and is connected, through an air tight passage or eontfiuit,",\\'ith a second bellows, also located aty the rear of the.' Stationary shuttle box. The secondi bellows has a larger eapaeity than the first; mentioned bellows, and is adapted to be filledw'ith air, or expanded, preferably by the active shuttle, when it enters the stationary shuttle box. 1ion of the larger bellows will cause the p artial exhaustion of air from the smaller bellows. and the. collapse, or partial collapse of said smaller bellows will operate the feeler, and through eonneetionsto the wefty replenishiug meehanism. will, on the substantial exhaustion of fillingl in the active shuttle, put. into operation 'sai'd mechanism to supply fresh filling.

My invention consists in certain novel' features of' construction of my improvements. which are adapted to be applied to. and used on any well known form ot weft reiilenishinp,a loom having a magazine for bobbins or fillinggl carriers, which magazine is either stationary, or movable.

l have only shown inV the drawings a detaehed portion of' a stationary shuttle box at the magazine, end of' the loom` with rny inlproveniente: appliedthereto, suftieient to enable those skilled in the art to understant'l the eonstruetion and operation thereof.

Fig. 5 '-orrespeuds to Fig". 1, but'I shows some of: the parte shown in Fig. 1, in a difl'erent position, and also shows some additional parts. Fig. t3 shows, on an enlarged seule. a modified eonstruetion of the filling deteetor or feeler shown in the previous ures, and Fig'. 7 is an end and sectional View ln the a eeompanying drawings, 1 is a pontion ot' theeaeefplate at the end of the lav@ The expanis the rear wall of a stationary shuttle box, 3 is a self-threading shuttle, which may be of any usual and 'well known construction, 4 is a bobbin, and 5 the filling thereon.

Secured to the rear side ofthe wall 2 is a plate (3, which in this instance has suitably mounted thereon two pneumatic devices, in

'the form of . bellows 7, and 8. The plate (3 is material 8 connecting said members. On

the movable member 8 of the bellows 8 is secured a plate 9 having an inwardly extending end part, preferably with a loop end 9 thereon, which is adapted to enter through an opening 2 in the rear wall 2 of the stationary shuttle box. The end 9 eX- tends in the path of, and is adapted to be l engaged by the outer end of the shuttle, as it enters the shuttle'box, as shown in Fig. 5.

A helically coiled expansion `spring 10 bears at one end against the plate 9, or the outer side of the movable leaf or member 8" of the bellows 8, and at its other end against a plate or extension 11 extending up from the rear of the race-plate 1, see

I' Figs. 1," and 5. The spring 10 acts to move inwardly the movable leaf 8, and to collapse the bellows, as shown in Fig. 1, after the shuttle has been picked from the shuttle,

box. A. plate l2 supported on the outside of the 'leaf 8 to have a rocking motion, is yieldingly held in its lowered closed position by a spring wire 12%, secured. to the movable leaf S, and said plate 12 forms an air tight cover for an opening 8a in the leaf 8. 'lhe plate 12 acts as a valve, which is automatically opened 'by the engagement of the inner end of a screw 1st, in this instance carried on the plate l1, whenever the movable leaf 8 of the bellowsvis moved outwardly, as shown in Fig. 5.

'Vhen the bellows 8 is expanded, through the action of the shuttle, as shown in Fig. 5, the air from the smaller bellows 7 is partially exhausted through the conduit 6, and

the bellows 7 is collapsed by theaexternal air pressure, against the action of the spring 15,

attached at one end to the i'novable leaf 7 erably of a frame or loop-like device 1G,

which is preferably made of a flat piece. of

metal bent into the shape shown, and secured y upon the movable leaf or member 7 of the vbellows 7, which has the stationary leaf 7 attached to the platevG, and the flexible material 7 connecting the two leaves, 7 and 7.. vThe filling detector or feeler 16 is adapted to extend through an opening Q in the'rear wall of the stationary-shuttle,

which is adjustablysecured in the end vof i an arm 18 having a hub 18 loosely mounted on a stud 19.

Extending out from the hub 18 is an arm or latch 20, having a hook end 20', which is adapted to hook over and engage a projection 21 on a lever 21. The lever 21 extends in a groove or recess -1 in the upper side of the race-plate, see Fig. 2, and has its attached end offset and provided with aA -hub '21, fastened on the upper end of a vertically extending rock shaft 23, which is mounted in bearings 1 on the lower side of the race-plate 1, see Fig. 2.

circles the stud 19, see Fig. 2, and is secured at one end to a collar 24 fast on said stud, and at its other en'd to the hub 18 of4 the arm 18, and acts to yieldingly move said arm and the hook arm 20, to cause rthe hook end 20 thereon to be held in engagement with the projection 21- on the lever 21, to hold said lever in the position ,shown in Fig. 1, and also hold the dagger'Q in its inoperative position, shown in Fig. 1.

The dagger 25 has a hub Q5 which is fast on the vertically extending shaft 23, see Fig. 2. The lower lend of the shaft 25 has thereon, in this instance, a torsion spring 20 which encircles the shaft and is attached at one end to the bearing 1, and at ils other end to a collar 27 secured-on the lower end of the shaft 23 by a set screw 28. The torsion spring 26 acts to partially rotate thc` 'shaft Q3 and carry the dagger 25 into operative position, when the lever 2l is released by the hook arm 20, as shown in Fig, 'l`he dagger 25, when in operative position, cxtends in lthe path of and is adapted to engage, in this instance an extension Q9. on the end of the transfer lever 29, see Fig. .5, which forms a part of and is connected with the transferring mechanism of the maga# zine, in any usual ainlwell known way. i

A helically coiled torsion spring 24 en- (in the outer end ol' the lever '21, on i stud 3 0. is in this instance mounted roll 2l, which is adapted to extend into the path of and engage the inclined (ir-beveled edge i12 on a stationary arm 32, on the baclnvard moven'ient of the lay, to cause the moi-ement of the lever 2l vand also the dagger 35, from the. position shown in Fig. 5,

to the position shown in Fig. l, and allow the eixgagement'ott the hook arm 20 with the projection 2t on the lever 2l, to loek or hold said lever and the dagger 25 in their inoperative position.

ln Figs. 6, and 7 is shown'a modified eon' struction ot my feeler or filling detector meehanism. ln said figures, the filling detector or feeler, instead of being made in one part, as shown in the previous figures, is made in several parts, and consists of a plate or strip 32:3, secure-d upon the movable member 7 ot' the bellows T. The outer end otA the plate 325 carries a stud or pin 3l, to which is pivotally attached one end ot' a Curved shaped strip or plate 35; the other end ot said strip 3.3 has in this instaure attached thereto two plates 35', havil'ig a spare between them, and preferably provided with teeth, or serrated edges 35 on their engaging sin'faees. The twoplates 35 carry a stud at their inner ends, on which is pivot-ally mounted a plate 3T, having teeth 3T on its engaging end. lhe plate 3T has an elongated slot or opening 37 therethrough. through which extends a stud 3S on an ear or lug Zit) extending clown from the plate 33, see Fig. (5. A helieally coiled expansion spring l() extends between au extension 37 on the plate 25T, and the outer'side ot' the plate 3?), and acts to yieldingly move the plate 37 on its pivotal support, to eause it to enter between the two plates 3o on the plate 35, and into its inoperative position.

lv'hen in the opeiation ot the loom, the plates 35 having-the tooth portions ilo thereon, are moved toward the bobbin to eugage the tilting. as shown in Fig. t), the tilling is depressed, and the engagement ot' the teeth 3T on the movable plate 237, will rause said plate. by its engagement with the tilling, to be held in its inoperative position as long as there is a sutlieient. amount' ol tilting on the bLobbin. lVhen the filling on the bobbin 'is praetieally or substantially exhausted. as shown in Fig. (3, the t'ew layers ot tilting on the bobbn will not. be depressed sntlieiently to eause the teeth 25T on the plate 2li to be held. and said plate will move awa v from the plates C35". as shown in Fig. t'. and allow the further movement o't' the plate 3T. and Consequently allow the extension itil on the plate itil to engage an adjusting Asei-ew. Corresponding lo the adjusting serew lo. shown in Figs. Land 5.and above dest-ritual. and release the lever ift and thil dagger 2.3, to put into operation the wett reptenishing meehanism. all as will be tully understood by those skilled` in the art.

with the drawingsl the operation otE my improvements shown in Figs. t to 5, will be ueaflil'v understood by those skilled in the art, and briet'ly is as tollmvseJlVhen the loomisaiii operation, and the shuttle is in the shuttle box on the opposite end otl the loom from that. shown in the drawings, or is in transit lrom said shuttle box to the shuttle box shown in the drawings, the parts of my tilting detector mechanism will be ni the position shown in Fig. 1. When the shuttle enters the'shuttle box shown in the drawings, and approaches the end of its travel, the rear side ot the shuttle, near the outer endv thereof, will engage with the loop end 2) on the plate t) lattached to the movable member of the bellows S, as shown in Fig. 5, the parts ot' the bellows 7 being in the position shown in Fig. l, and .will move out Said plate t) and with it the movable l mt' S of the bellows S, and cause the inner end of the screw t4 to engage the outer end ot the plate l2, to move said plate, against. the action of the spring 123, into the position shown in Fig. During the outward movement of the leaf 8, a partial vaeuum is formed in the bellows tu', causing the air in the smaller bellows 7 to pass out into the larger bellows S, and the pressure from the external air to move inwardly the leatl T of the bellows T, against the aetion ot' the spring 15, and collapse the bellows T, as shown in Fig. The inward movement ol the leatI 7 ot the bellows 7, ea rries inwardly the tilting detector or teeler lo, and eauses it. to enter through the openingr in tlte rear otl the stationary shuttle box, and through the openingl in tln` shuttle, and engage with the tilting on the bobbin in the shuttle. When the end of Athe valve plate l2 (comes in eontaet with the end otl the lever ll, the opposite end ot. said valvt` plate is raised s 'utiieiently to allow the air to enter the bellows S through the opening S, and through the eonduitl' enter and till the bellows 7. as the leal' i is being drawn bael by the spring l5 to its inoperative position. shown in Fig. l. As long as there is a sutlieient amount otf tilting on the bobbin, the loom eontinues to operate in the normal'way. and when the shuttle is picked Vtrom the shuttle box showl. in the drawings, the spring lt) arts to return the movable leatf H" ot. the bellows b', to its inward orolosed position, and the spring lill aets to elose the plate or valve l2 over the opening H, and the .spring to arts to move outwardly the leat' T on tlu` bellows T, and with it the fillingl detta-tor or lieeler lo, to earry the same out ot' the shuttle box. as shown in lfig. l. lVhen the tilting' on th aetive shuttle is praetieally or substantially exhausted, as shown in Fig.

, the inward movement ot' the tilting del i teetor or teeler ttt is snllieient. to cause the l* rom the above desrription in eoi'mmtlon f extended end ttt thereotl to engage with the screw 17 on the arm 1S. amlrork said arm, and with it the hoohY arm 20, to disengage it from' the projection )l on the lever 21, and
