WEFT-REILENISHING LOOM.

Specification of Letters Patent.

Patented Dec. 21, 1909.

Application led March 3, 1909. Serial No. 4811,030.

To all whom it may concern: A

Be it. known that l, BENJAMIN F. Mc- (li'ixnss, a citizen of the United States, residing at lVorcester. in the countyof \Vorces ter and State of Massachusetts, have invented certain new and useful Improvements in lVeft-Replenishing Looms, of which the following is a specification.

My invention relates to a weft replenishing loom, and particularly to a ii'iechaiiical lling detector mechanism for weft replenishing looms, ot' the class which is located at the magazine end of the loom, and onv the loom side or end, and is provided with a feeler to feel through an opening in ythe binder and in ,the front wall of the shuttle box, and through an opening in the shuttle, and engage with the filling on the bobbin, or filling carrier in the shuttle, on every other forward movement of the lay.

The. objcctoff my invention is to improve upon the construction of the filling detector mechanism of the class referred to, and more particularly to provide a more sensitive and delicate filling detector mechanism. having a feeler to feel for and detect the practical or substantial exhaustion of filling on the bobbin in tli'e ruiming shuttle, without regard to the size ot the bobbin on which the filling is wound, or .he position of the bobbin in the shuttle.

In myimproved filling detector mechanism, which is preferably located on the frame or stationary part ot' the looiii, l providea slide having a reciprocating movement, and which is moved into the shuttle to engage the filling on the bobbiii, through an opening in the binder and inthe shuttle box' and iii the side of the shuttle. second slide is attached to the first mentioned slide,

4.and is loosely held thereon, and is adapted to finove iii a direction lengthwise of the bobbin, and at right angles to the direction of movement ot' the first-mentioned slide. When the first-nientioned slide engages the lling on the bobhin in thc shuttle, it de- Ipresses the filling andycauses the secondn'ientioned slide, by its engagement with the filling, to he held in its inoperative position. When the tilting on 'the hobhin pra ically or substantially exhausted. the few layers of filling on the bohbin will not he depressed suflioiently io prevent `the transversely moving slide from operating. and :i lever, which yieldingly Aoperates said slide, will moveI it.

.- ix'teiiding arm t along the filling on thel bobbin, and cause a bunter on the ti'ansferrer arm, which is connected with and operated by said lever, to be moved into the path of a rdagger on the lay, to be engaged by said dagger, to operate the transferrer arm and cause a t'resh filling to be inserted vinto the running shuttle on the san-ie pick, all as will he hereinafter fully described. l

My invention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

l have only shown in the drawings a detached portion of a weft replenishing looin with my imprveinents applied thereto, sut'- ficient to enable those skilled in the ait to understand the construction and operation thereof.

Referring to thel drawiiigs:-11`igiire l is an end View of a detached portion of a wettreplcnishing loom with my limprovements` combined therewith; also a section, on line 1, l, Fig. 2, looking inthe direction ofarrow a, same figure. Fig. 2- is a section, on line 2, 2, Fig."1, looking in the direction ot' arrowrb, same` figure. Fig. 3 corresponds to Fig. 2, but shows some of' the parts in a different position; some. of the parts shown in Fig. 2 are not shown in this figure.` Fig. 4 corresponds to'l'Fig. 2,'but shows some of the parts in a differentJ position, and, Fig. 5 corresponds to Fig. 3, but shows some ofl theI parts in a ditierent position.

In the accompanying drawings, l is a portion of the loom sideI or end fiaiiie,having a stand i2- secured' thereon, on which is mounted the lower portion of' the stand 3 fotI the rotarv .magazine 4,5 which carries the hobbins'.orQfilliiig carriers 5, having A.filling (3 thereon.

The shuttle binder, not shown, has an opening therethrough for the passage of the filling detector. p

All of the above mentioned parts may be of the usual and well known construction.

'l`he stand il has an extension 2. sec Fig.

'2. on which is secured a downwardly extending hracket l2, sec Fig. l, having a boss l2', see Fig. Q, carrying a stud 13. on which iS pivotally mounted the hub 14 of' a Shoe ingr the filling on the 14. An arm 14 extends out from the hub 14', and has connected thereto one end of a heli-ally coiled eontractionspring .15; the other end of said spring is' connected to some stationary part of the loom, not shown. 'lhe spring l'jis adapted to yieldingly move the shoe 14 in'one direction. Secured on said shoe 11 is an u wardly extendingarm 16,-whic'h is operated) every other piek from some moving part of the loom, not'- shown, through .a connectorl?, which has o. rod#V head 17 pivotally mountedjon a stud 19 on the arm 16. The upper end of the'arm 16 is ada described.

Secured on the bracket l2 and extending vupwardly therefrom is a bracket or-stan 20, see Fig. l, the upper end of which has 'a boss 20', on which is adjustably secured by a bolt 21, theboss 22 of-a stand 22, see Fig. 1. The upper enlarged portion 22-of the stand A22 is adapted to hold and guide the slide plate 23 of the filling feeler mechanism. The outer end of the slide pla-te 23 isl bent upwardly at 23', see Fig-1, to re ceive `and hold the rod 24, which through the upper bent odset end 16 on the lever 16. The inner end of the slide late 23, enters through an opening inthe ront wall of the stationary shuttle box, and through an opening in the shuttle, to engage the filling. I ts engaging end may have teeth thereon, if preferred. 'Adielically coiled expansion springl 25 encircles the rod 24 and bears at one end againstthe oi'set end 16 on the lever 16, and at its other end against the vnuts 2l on the rod 21, see Fig. v2. The inward movement ot' the arm 16,' through the spring 25, acts to vieldingly move 1nwardly the slide plate 23, and cause its inner end 2:1 to engage the bobbinin the vshuttle when the lay is on its forward movement, see Fig. 3. It' the slide plate 23 .enters tar enough into the shuttle ll, `see Fig. 2, the inclined edge 23 on said plate 23 will engage a pin 11, which in this instance is se cured in the shuttle at the inner end of the openinpr 11" in t-he'shuttle, to positionthe shuttle, preparatory tothe feeler 23 engagractically or substantially` exhausted bobbin, seeliig. 2. A second slide 26 is mountedon the inner end ot theslide 23, and 'is held thereon by a headed @pin or l through an elongated slot 26 in the slide 26. Said sllide 26 has a movement with the slide 23, alu rig-ht. angles to the 'movement of the slide 23. The projections 23 and 23b on the slide 23, see Figs. 'lhe inner end ot' the slide 26 is adapted to ei'ig'age with the filling on the bobbin: Suid .nd may he provided with teeth if desired.

hub 28 pivotally mounted on a stud 28 secured on the plate 23. llxtending out from one side of the hub 28 'having an' carer/lug 28C thereon, V'which is adapted'to loosely receive a rod 29, which extends through the upper end 16 of the The rod 29 has two nuts 29il on its inner end. which engage the lug 28c to rock the lever 2S. A helically coiled expanencireles the rodA 29, and bears a-t one end against the lug"or-projection 28,` and yat its other end against the upper end ot'v thearm. or lever 16, and actsl to the left, seeFig. 2, and also the lever 28 on its ivotal stud 28 to move the slide 26 lengthwise of the bohbin,` when said' lever 28 is unlocked fronrthe slide and the filling is practically orpsubstantiallv exhausted, as shown in Fig. 2.

On t-he outer end 28 of the pivotally mounted lever 2S is a'stud or pin 28a, which extends upwgndly into an elongatedslot ory opening 30` in the outer end of an arm 30. which slotl hasan offseton one side. .The inner end of, the arm v30 is secured upon the bunter 31, which is pivotallyf mounted at 31 on the downwardljyfextending arm 7 on the transferrer'arm T. see Fig. l. f

On-the front otl the lay beam 9 is secured a stand 33, and a ,dagger 32' is adjustably mounted on said stand, and is adapted to engagethc bunter 31. as the lay beats up,.vvhenA said bunter moved into the path of said dagger, as shown in Figs. 2-and 4. Near the inner end of the lever 2S is in this instance a stud or pin 2S extending np from said lever. and preferably ot' curved4 or camlshape on one side. and flat on the other, The stli'dor pin 2S on the lever 28 coiiperates with a lever 37. havin;v the curvedor cam-shaped"engaging end Bia," back ot which the pin 2S" Iis adapted to pass, to hold the lever 2S and the Islide 2 6 thereon in their' normalA inoperative position. as and. The lever Sli' has its hub 37' in this instance pivotally mounted on a stud or pin 3S, serured on the lower securedtothe lay beam. and a s iral s )ring 4th-attached at one end' to a col 'ar-42 ast on said stud 3S, and at. its other end to the hub 37 on the arm 37, acts toyieldinglyhold the arn1 37 in its normal raised position, and against ya stop, not shown. By means of' the helieally coiled toiiiin springgl, the arm 37 is its ralsed position, and may be moved backward, to allow the pin 2,8" to pass by it, in` case said pin not properly positioned to pass back ot' thercurved arm37 on said arm 37. e

From-'fthe above description in connection wjththe drawings the operation of my irn-v is an arm 28.I

. 55 also mo ve provenients will those skilled in the art, and briefly is as i'ollowszy When the loom is' operating normally and there is a sutiicientfainountof lling on the bobbin, as the lay `lmoves forward, the slide 23, carryingthe` lever 2S, and the second y ,sjlidGQGTWilLQbe,moved c opening at the front of the shuttle box and 1o the opening in the'shuttle, as shown in Fig. 3, bythe' inward movement of the upwardly extending arm 16, through 'the spring on the rod 24. The arm 37 carrying the en- A gaging end 37, willremain in its normal l position, and the pin 28b extending back of the extension 37a` will holdI the leverl 28 in "its normal position, against' the action of 4.the expansion spring 29 on the rod 29, and

:the a'rin 30' will reniainin its normal posi- ."ition, with the bunter 31 ont otY the path of Fig. 3. After the engag- 'ing ends of the slides 23 and 26 have enaged the filling on the bobbin, as shown in ig. 3. the slide. 23 and the lever 23 thereon,

and the slide 26, are moved outwardly by the outward movement of the arm 1G,

n -Athrough the engagement of the upper end of said arm with the spring 34 on the pir 29, and also its engagement with the roll 35, as

-b shown' in "Fig 5; tlielseveral parts are held jin their'sanie relative positions, and this operation is repeated every other forward movement of the lay, sutiicient amount of filling on the bobbin.

yWhen the filling on tically or. substantially exhausted, 'as shown in Fig. 2, the slide 23 iskmoved forward suticiently to allow the pin 28b to pass by the engaging projection 37a on the arm 37, and 40 allow the expansion spring 29 to act, to move the lever 28 on its pivotal pin 28'", and cause-the slide 26 to,` be moved to the left, by the engagementof the inner end of slide, and the arm 30,

said lever 28 with said .1.5 connected with the bunter 31, will be moved to the right, to bring the bunter 31 in theY path of the dagger 32, as shown in Eig. 2.

Inthe continued operation of the loom, the outward movement of the arm 1G will move the slide 23 outwardly and away from the. shuttle, as shown in Fig. 4, and the engagement of the inner nut 29 on the rod 29, with the extension; 28 on the hub 28', will move th lever 28 on its pivotal Support, and

' the slide 2G back to its normal position at theiight, and also bring the `pin 28b back of the extension' 37'1 on the arm 37, so that in the continued backward movement of theslide the pin 28" will be moved back f theexteision 37a, to lock the lever 28 and the Slide 26 in their inoperative position. :The iext forward will move the pin 23*t on the'lever 28, in the in the lever' 30, to the front narrow 1 of said slot, to move said lever 30 into be readily understood by forward to entei` the as long as there is a` the bobbin is prac` shuttle to position the shuttle,

movement of the slide 23 its normal inoperative position,

as shown in on tliebobbin is substan When the filling tially exhausted, -as shown in Fig. 2, in caso the shuttle is not in propel' position in the shuttle-box, the inclined edge on the slide 23 will engage the pin 11 in t-he shuttle, and acty to move outwardly, or tlc, preparatory to the removal of the bobbin from the shuttle, andthe transfer of a new bobbin.

The advantages of my improvemei'its willl be readilyl appreciated by thosc skilled in the art. The transversely movable slide 26,

f which, when the filling is practically or sub.

stantially exhausted acts to put into operation the filling transferring mechanism, is, through lever 28 and with the bunter 31 ivotallyvmonnted on the downwardly extending arm-7 on tlietransferrer' arm 7 'so slide 2G 'on detecting the practical'or substantial exhaustion of filling inl thev active shuttle, is communicated, through interino-.u i90 diate connections, directly to a partof the transferring mechanism, to canse the immo-- diate' operation of the transferrer arm, asv the lay advances on its forward movement and the dagger 32 engages the bnnterlflt will be understood that the details of construction of my improvements may be varied if desired.
