To all whom 'it ma concern:

Be it known tint I, BENJAMIN F. Mc- (iliixnss, a citizen of the United States, residing at 'orcester, in the county of Worcester and State of Massachusetts, have 1nvcnted certain new and useful Improvements in Filling-Detector Mechanism for llfeft-Replenishin Looms, of which the following is a sieci cation.

My invention relates to a fillin detector mechanism for weft replenishin ooms, and particularly to a mechanical fil mg detector mechanism havin a feeler, which is prefer ably located on tie end of the lay, at. the magazine end of the loom, and at the rear of the stationary shuttle box at said end of the lay, and which is adapted to enter through an opening in the rear wall of the shuttle box, and throuf'h an opening in the shuttle, to engage the lling on the bobbin in the shuttle, preferably at. every other forward movement of the lay, and on the substantial or practical exhaustion of the filling in the active shuttle, operate mechanism connected with the weftre lenishing mechanism, to cause a fresh bogbin to be supplied to the active shuttle, in place of the subat initially exhausted bohbin, in the usual and well known way.

The object of my invention is to improve upon the lilling detector mechanisms of the class referred to, and more particularly to provide n. filling detector mechanism for weft replenishinw looms, comprising two members, both a n )ted to enter an openin in the shuttle, an en nge the filling, and means to move one o said members rela,- tively to the other member in the direction of the length of the bobbin, and connections l intermediate one of said members and thc weft replcnishing mechanism, to canse a fresh bobbn to he supplied to the active shuttle on the practical or substantial exhaustion of the filling on the hohbin in the active shuttle.

In mi' im|novements as shown and dcscribed herein I provide as one member of my filling detector mechanism, preferably a slide having a reci rocatiug movement., which is moved into t le shuttle in a direction at. right angles lo the axis of the bohlrin to engage the filling on the hohbin und is yieldingly held in contact with the filling. l provide as the second momia-.r of my filling detector mechanism, which is adjacent to the first-mentioned member, refer-ably a second slide which is prefer-ab y supported on the first-mentioned slide, and is moved therewith, and is also moved in the direction of the len h of the bobbin. When the first mentions slide en ges the Elln on the bohhin in the shutt e, 1t depresses t e filling and causes the second mentioned slide, by its engagement with the filling, to be held in its inoperative position, but when the filling on the bohbin is practically or substantially exhausted, the few levers of filling romaining on the bobbin will not be depressed sufficiently to prevent the transversely moving slide from o erating, and nn actuating s ring for sai slide will move it. along the fi ling of the bobbin, and put into operation the mechanism which operates the weft replenishing mechanism which may be of any ordinary construction.

My invention consists in certain novel features of construction of my improvements, which may be ada ted to be applied to and used on any well own weft replenishin loom having a magazine for bobbins or fil ing carriers, either stationary, or movable.

have only shown in the drawings a de- `tai-.hed portion of a stationary shuttle box at the magazine end of a loom, with my improvements a lied thereto, suflicient to enable those skll ed in the art. to understand the construction and operation thereof.

Referring to the drawings Figure 1 is a plan view of a detached portion of a stationary shuttle box with my im )rovements applied thereto, lookin in the irection of arrow a, Fig. 5; some o the parts are broken away and others shown in section, and some parts shown in Fig. 5 are not shown in this igure. Fig. 2 is an underside view of the parts shown in Fig. l, looking in the direction of arrow b, Fig. 5. Fig. 3 corresponds to F ig. 1, but shows some of the parts in a different position. Fig. 4 is an underside view of the parts shown in Fi 3. Fig. 5 is u Section, on line 5, Fig. 1, ookng 1n the direction of arrow c, same figure, and also shows n portion of the lay beam, and some other parts not shown in Fig. l. Fig. 6 is a plan view, eorrespomlng lo Fig. 1, but shows somo parts in n different position, also shows some parts which are not. shown in a the necompan ing drawings, l. Fig. la n portion of the ny beam, E! is a detached portion of the back wall of a stationair shuttle box, 3 is a shuttle, carrying a bo bin 4, havin tillin 5 thereon. Secured on the rear side of t e back wall Q and extendin out therefrom is a stand 6, the np er side o which has undercut or rooved (3', see Figs. 2, and 4, which Orm a trac or way for a slide 7, having a reeiprocatin movement. toward and away from the ling in the shuttle, through an openinghfl in the back wall 2 of the stationary s uttle box, and an opening 3' in the rear of the shuttle 3. The en ging end of thc slide 7 is preferably rou cned or corrugated.

The sli e 7 has a rearwardly extendin arm 7', carrying at its end a pin 8, to whic is connected one end of a helically coiled contraction spring 9; the other end of said spring t) is connected to a pin 1 0 on a lever 11 having a hub 11' which 1s adjustabl fastened by a set screw 1'2 on a vet-tica y extending shaft 13, which has a bearing in a stand 14 secured to the back wall 2 of the stationary shuttle box. Extending out from the hub 11' of the lever 11 is an arm 11 having pivotally connected thereto a rod head 15', on a rod or connector 15, sce Fig. 6. The other end of the connector 15 has a rod head 15" thereon, which is pivotally connected with one arm of an angle lever 16 having its hub 16' ivotally mounted on a stud 17 secured to e back of the lay, see Fig'. (i. The other arm of the angle lever 1G carries a pin 16" te which is pivotall connected the end of, a connector t8, in t lis instan leading downwardly, and connected with operating parts of the loom, not shown.

Through the connector 18, angle lever 16, connector 15, and arm 1l", the lever 11 is rocked or moved at. regalar predetermined intervals, toward the stationary shuttle box, and through the sprin t), attached to said lever 11, the slide 'i' wil be yieldngly niovul toward and into engagement with thclilling 5 on the bobhin -l in the shuttle 2l. The backward or outward movement of the lever 11 will canse it to engage a pin or stud 7" on the slide 7, and positively move back or outwardly said slide. to carry its.: inner cnaging end ont of and away -from the. opening through the shuttle il. as shown in Fig. t'i.

On the underside of the slide 'i' is in this instance a screw 15), scc Figs. 2 and 4, on which is loosely pivoted a three armed lever 20. One arm .10 of said lever 20 has a pin 2i, see Fi 2 and 4, to which is attached one and ov a lighthelically coiled contrae tion spring 32. The other ond of said spring 22 is attac wd to a in 23 on the carved or cani shaped und zt of an arin or lever 24. The Indi 2l" of tlalever 24 is set-.inval hy o sot; screw "J5 on the lower und of the vertically extending shaft. lil, non Fig. 5, to :novo with said shaft, which shaft is rotated or rocked hy tho arln ll", and the connections to said arm above described. The curved or cani shaped end 24 of the lever .24 is adapted to engage a pin 2G on the arm :20' of the three armed lever 20. On the three armed lever Q0 is a second arm 20, which extends toward the shuttle box, and has an elongated slot 20 therein, into which extends a pin 27 on the transversely moving slide 2S, see Figs. f2, and 4. The slide 28 extends in this instance upon the underside of the slide 7, and has an elongated slot 28' therethrough, through which extends a stud or pin 2t), sec Fi 5, secured upon the nndeiside ofthe sli e i', and having a head 29 which extends over the edges of the slot 28 and acts to attach the slide :28 to the nuclei'- side of the slide T. A projection 28" on the slide 28 extends in a notch or recess in the underside of the slide T, at one edge thereof. see Figs. '2 and 4, and acts to hold the slide 28 relative to the slide T, so that said slide Q8 may have a transverse motion relative to the slide 7, or in a direction at right angles to the motion of the slide 7 and also in n direction lengthwise of the bohhiii 4 having the filling 5 thereon.

The slide 28 has an engagin end 28* thereon, which is preferably ma c inclined, as shown, and also preferably roughened or corra ated and is adn ted to engave with the fi ling 5 on the bebhin 4, when tie slide 7 is moved toward the bobhin. as shown in Fig. 4. The engaging end of the slide Q8 preferably does not extend to the extreme end of the slide 'i'.

The stand (l has an elongated opening 6* therethrough, thron rh which extends a pin 30, which is adjustalily secured in said o ening by a nut 30', see Figs. 2 and 3. he pin 30 has in this instance a square shaped owcr end, see FMH. 2 and 4, which is adapted to engage the onter edge of the arm 20" of the lever 20, as long as there is a certain amount of filling 5 on the bobbin 4, sce Fig. 2, to prevent the slide 28 from Ii'iovng sidewise. 0n the three armed lever 20, a third arm 20' carries a pin B1, which extends into an elongated slot 32 in a lever 32, having the huh 32" pivotally mounted on a screw :S2-l secured upon the upper side of the stand (i. The outer end of the lever 32 has in this instance a sind 32 thereon, which is adapted to be moved into the patti of a lever 34, shown in section. in Figs. l, and 3, to move said level', on the forward niovenient of tho lay, and canse it. through intermediate connections. not shown, of any nsaial and ordinary construction in watt. re denis-hing looms` lo pnt into operation the weft re|lilunishing olechnnisan, to supply a fresh lio hin in plat-r of the solist-anim ly exhausted liolihin, in the nsnal way.

Fast on thi' connector rod l5, son Fig. (i. is a collar 3.1. having an extension 215' thereon, which extends in the path ot' and is adapted to engage an arm 36 having its hul Bti' fast. on the shaft 3T, which is loosely mounted in a bearing 2" on the hack wall of lthe stationary shuttle box. Fast on the 5 other end of the shaft. 3T is the huh 38' of an arm 38. The arm 38 extends npwardly from said shaft 37, (see Fig. 5,) and is adapted to be en ed by the transferrer arm, not shown, o t e transferring meehanism, not shown, or other suitable |nechanism, when the bobbin is being transferred, 'to cause, through the movement of said lever 38, shaft 3T, and arm 36, the move ment of the connector 15, and through arm 11, the movement of the arm 1l, to canse it to engage the pin T on the slide T, and move said slide away from and out of the shuttle, as shown in Fig. 6.

From the above description in connection with the drawings the o eration of my improvements will he rea ily understood bythose skilled in the art.

When the bobbin has a sutlicient supply of filling thereon, as shown in Figs. 1, 2, and

the engagement of the engaging end of tho slide T with said bobbin,.- through the movement of the arm 1l, and its operating mechanism, and the spring 9, at regular predetermined intervals, preferably at ever' other forward movement of the lay, wi l form a slight depression in the filling on the bobbin, and will car the engaging end 28' on the transverse slice 28 into en agement with the filling, and the friction o. said end with the filling, will hold the slide 28, as shown in Figs. 1, 2, and 5, and revent any transverse movementthereof, re ative to thc slide 7, until the filling on the hobhia is sohstantially exhausted.

W'hen the filling 5 on the bobbin 4 is )ractieally or substantially exhausted, as s town in Figs. 3 and 4, the increased movement of the slide 7, carr ing the lever 20 thereon, will cause the. #e of the arm 20" of said lever to pass b the stud 30, and as there is not snicient lling on the bobbin to hold the engaging end 28 of the slide 28. the light spring: '22 will act, to move the lever 20" toward the loft, Fig. 4, until the pin 26 engages the cam shaped end 24" of the arm 24, and also more the arm 20'", and through the pin 31 thereon, the lever 32 will be moved, to carry the stud 32 thereon into the path of the lever 34, see Fi". 3, so that on the.

forward movement of t e lay said lever 34 will be operated. and through connections to the weft replrnishing mechanism. will put into operation said mechanism, to supply a fresh hobhin in place of thel substantially exhausted bobbin.

lt. will he understood that the. detailsl of construe-tion of my improvements may ho varied if desired.

l do not limit my invention to the )articu- 05 lar form and instruction of the filling lletector mechanism shown and described, as my invention is intended to cover broadly, a fillimlr detector mechanism for weft replenishmg looms, com rising two adjacent members, both adapted) to enter an opening 79 in the shuttle and engage the filling, and means to move one of said members relatively to the other, in the direction of the length of the bobbin, to cause the operation of the weft replenishin mechanism on the Eractical or substantia exhaustion of the lling in the actiw shuttle.
