This invention relates to improvements in thread parters forlooms and it is the gen eral object of the invention to provide a simplified device of this nature which shall act to sever the thread at the eyeend of the shuttle, preferably by advance movement of the shuttle. i

In weft replenishing looms there usually remains at the time of transfer aweft end which extends from the selvagealong the front shuttle wall to the weft delivery eye,

through the latter and down through the bobbin slot in the lay to the bobbin can. 'Unless this weft end is extracted prior to'the pick immediately following transfer there is a likelihood that it will be whipped into the shed to form an imperfection in the cloth. It has been proposed heretofore to cut the end at the shuttle feeler, clamping way it is necessary to deal with but one end,

the part extending beyond the shuttle eye being extracted by the expelled bobbin.

It is a further object of my present invention to provide a cutter or thread parter which shall reside in part in a plate oranvil on the shuttle and in part in a movable weft parting edge which is brought into contact with the anvil preferably at the time of transfer. The anvil is carried by the front wall of the shuttle and disposed so as to extend across the weft end which usually ere tends longitudinally in alignment with the front delivery eye. In this connection I find it convenient to control the cutting edge through the transferring mechanism by a connection which normally holds the cutter out of contacting position'with respect to the anvil but acts when the transferrer arm descends to permit the cutting edge'to move rearwardly toward the anvil. In thisway the cutting elements move'towar'd each other alone.

In multicolor'weft replenishing mecha' nisms it is customary to locate the. weft de tector under the magazine where it may enter a slotin the front wall of the shuttle to de ployed it is desirable to insure a free path of and the cutting is accomplished by mo ,tion which is faster than that of the lay H extends from the shuttle eye to the thread I clamp. If the detector is not retracted sufiiciently removal of this part of thethread be rendered difficultby entanglement with the feeler finger. This is particularly true with high twist yarns." It is according ly another object of my invention to control the thread cutter and detector in'suoha way that when the cutter acts to release the thread at the shuttle eye the feeler will be moved forwardly to a point'where it cannot interfere with that part of the weft which may tend to snap from the eye toward the shuttle feeler clamp. It is desirable to accomplish this result whether the binder be on the front -with a shuttle carried groove for the-weft or whether the b nder be on the back and the front wall of the shuttle box engages only the upper part of the shuttle.

Another ob'ect of my invention is to ar-.

range the cutter so that two coacting parts I will have relative sliding motions,' either vertically or horizontally,'to assist in parting the weft, the relative motion being produced bya force derived from the shuttle and transmitted preferably through the anvil.

It is a still furtherobjectof the invention 1 to provide a cutter or parter which. will be des pendent for its operation uponthe actual presencein proper position of the shuttle, preferablythe shuttle eve, before a cutting operation can'occur. I I

Still another ob'ect of the invention is to rely upon pinching theweft between a part-- ing edge and a relatively hard surface The latter may be of a form such that it can be thought of as having beengenerated by the parting edge.

With these and other obje'ctsin view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth in the claims.

--"Referring'toFig. 1 I have shown a breast beam 10 and a lay 11 pivoted-at L, see Fig. 6. Front and rear walls 12 and 13, respectively, define the shuttle box for a shuttle S.

A loom frame 15 supports a multicolor weft replenishing mechanism 16 which may operate as shown in'Pate-nt No. 1930,7418. This 'inechanism comprises a'fiXed stud 17 on which is pivotally mounted atransferrer arm 18 having'a hub 19. The latter has a pair of depending legs 20 between which is pivoted a latch holder 21.jcarrying a latch 22., The latch can be raised by appropriate mechanism into the path of bunter 28 on the lay'forthe this invention.

purpose of depressing the transferrer arm 18.

Any form of weft detector may be used, that form shown herein being designated generally at D and comprising a rearwardly extending feeler finger 24 pivotally mounted on a slide-25 the forward end of'i'vhich is upturned as at 26. The detector ofitself may be as shown in my prior Patent No. 1,738,198

and formsno part of my present invention,

although the control therefore i s a 'feature of It is sufiicientfor present purposes to say that. the detector and slide 25' will move forwardly without angular movement whena working supply of weftis present, but when exhaustion approaches the finger will move angularly about its slide carried pivot and along a denuded bobbin to initiate a subsequent depression of the transfe'rrer lever forthe "purpose of effecting a change of bobbins in the active shuttle.

As shown in Figs. 5 and 6, the clamp which I use maybe mounted on a shuttle feeler of the type shown in Patent No. 1261,41? and comprises a stand 27 to which is.;pivoted a lever 28. The latter is connected to a link 29 which is raised when a transfer is to occur.

A shuttle feeler arm 30 is pivoted to'the lever and is resiliently held in'normal position by tached *toan operating rod guided in a swivel 36 on thestand 27. A spring-.87 between theswivel and a-collar38 on therod permits a limited yielding of the rod. Stop swivel and acts to open the j aw when the link 29 is raised. Forwardmovement of the shuttle feeler by engagement with the lay, as

reset the magazine, although this latter result need not. be accomplished by the shuttle feeler. Forward motion of the shuttle feeler caused by a misplaced shuttle will prevent transfer. i s The mechanism thus far described is of, common constructi m being substantially the same as that. found in the ordinary well-1 known stationary-magazine loom and in the aforesaid patents. I In carrying my invention into effect 1 provide two separate thread parting members whichyare brought into coaction at the desired time." The first member ccnsists of ahard or metallic plate 40 which, as shown in F 3, may be set slightly into the front wall of the shuttle and extend both above and below the delivery eye 41. Where a thread groove 4-2 extends longitudinally along thefront surface of the shuttle it will be interrupted by the plate. The plate is very close to the delivery eye and may be held in position on the shuttle any approved means. Q

Thesecond member C is mounted indea pendently of the shuttle. the loomside carriesa stand 51 which is adjustably mounted both for vertical and horizontal positioning on'the bracket. An up Wardly extending stud 52 on the stand, pivotally; supports a cutter lever 53 the hubof A bracket 50 on which is surrounded by a torsion spring 54 having such relation with the stand and lever asinormally to urge said lever in a counterclockwise direction as viewed in Fig. 1. The

effect of the spring is to move the member C 1 rear end of which may be provided with a knife edge 58. The latter extends above and below a'horizontal line passing throughthe delivery eye 11, and as suggested in Fig. 4,

the pivot 59 for the cutterblade is so placed with respectto the forward end of the bifurcation as to allowa limited angular :movement in a vertical plane on the partof the plate.* l j The left hand arm 60,0f the lever extends behind a depending-finger 61 cast integral with the hub 19 of the transferrer arm. The spring 54 holds this arm against the finger, but the transferrer arm is not moved bythe spring because the position thereof is determined by a relativeiy heavy torsion spring, 62 surrounding the stud' 17. These two torsional springs oppose each other, the

spring 62 being strong enough to overpower spring 5e. The finger 61 is so placed asto engage the upturned end 26 of the slide 25 at the'time of transfer tomov'ethe feeler finger 24 forwardly away from 'the'front wall of the shuttle. While the thread clamp which I employ near the inner end of the shuttle may be placed as set forth in the aforesaid Patent No. 1,261,417, yet it d iffers from that patent in that it has no cutter. -The jaw 34 moves angularly between two Clamping elements on the arm 30. One of these elements is guided onpins 71 carried by the arm and is held against the jaw by a leaf spring 72 anchored tofthe arm. The other clamping element 73 may be formed as part of the arm. While I have shown two different clamp elements 70 and 73 to coact with the jaw, yet one will suffice.

In operation, so long as a workingsupply of weft is present, the feelerwill move forwardly on detecting beats and will return without calling for a change. When Weft is depleted, however, a" change is called for 1 which involves raising the latch 22 into the path of the hunter 23 by lifter rod .80. At the same time the clampmoves rearwardly to the position shown-in Fig. 6 with the jaw in open position to define a thread receiv ing notch with the clamping elements. Un-

der these conditions, andwhile the bunter is still out of contact with the latch, the lever 53 is held with its right hand end forward because of engagement with the finger61.

Asthe lay advances, engagement of the hunter and latch will depress the transferrer arm, at which time the finger 61 will move forwardly. This action accomplishes two results, namely, spring 54: is permitted to move 1-;- the cutter C rearwardly,'and the feeler D is moved forwardly. As the cutter member G moves toward the advancing shuttle it will be approximately in the position shown in Fig. 4 with the cutting edge 58 slightly in I" clined. Before the lay reaches its foremostposition the edge 58 will engage the plate or anvil 4:0 and move'to the. dotted line position shown in Fig. 4:, to place the knife edge in contact throughout its length with the plate on "the shuttle. At this'time the the rate of cutting weft end T is extending acrossthe plate 40 so thatengagement of the latter :with the edge 58 will sever the thread at a point'close: lyadjacent to the eye of theshuttle. 1-" V v As the lay swings forwardly it will turn" about its pivot L, but the cutter G will nevertheless be able to remain "in contact with the face of plate 4 -0 despite tliechan'gingangular position of the latter. Duringthe forward motion of the lay subsequent to engagement 5 of the cutting members the edge 58 will slide along the plate 40 away from the'clamp,thus giving additional assurancethat the weftwill be cut.

It is important that the clamp shallcatch the thread prior to the parting at the eye, and to this endthe rear of the arm 30 is engaged and moved forwardly by a part of the lay. early enough in the advance movement of the latter to clamp the thread at the desired time; 7

Prior to cutting the feeler finger has been moved forwardly sufficiently so that; if the thread be of ahigh twist and tends to snap toward the clamp the likelihood of entangle ment with the feeler finger will be reduced if not entirely eliminated. f

' It will be seen that the relative movement between the cutter blade and: the shuttle wall is determined by two factors, -.first',' the advance movement of the lay and, second, the rearward movement of the cutter'C, so that is greater than that of thela-y.

A templecutter 81 of any well-known construction may be employed to sever the weft end. T adjacent the selvage on. a subsequent pick. ,7

From the foregoing itwill be seen thatI have provided a simpleform of threadparter which depends upon pinching the weft between a hard surface on the'shuttle and a relatively sharp edge'on a cutter blade, and'the" latter is so mounted as to align itselfvertically with the shuttle surface to have contact therewith as the lay moves around its pivot.

Itwill also be seen that the weft detector is retracted a sufiicient distance to be out of the path of the weft which is released by I V the parter should it tend to snap back toward the thread clamp. Furthermore, the thread is clamped at a point intermediate the selvage and the shuttle eye sothat this entire length of weft remains intact, thereby making it necessary to manipulate but one piece of thread; aAgain, it willlbe noted because of the control eXcercised by the finger 61 the cutter contacts with the anvil only during I the act of transfer and the rate of cutting is greater than the rate of motion of the T25 lay. F urthermore,:the.members may be interchanged without departing from the'spirit of the invention. :Also, the edge 58' slides along the plate while in contact' therewith, and in this connection it is convenient to 130 think of the plateas having a surface that couldhave. been generated vby the cutting 5 each other..
