To all whom it may concern:

lie it known that I, Jam's Mane-vac, a citizen of the ignited States, and resident of Pawtucket, c unty of Providence, State of lthode Island. have invented an Improvemeat; in Thread-Parting Mechanism for Looms, of which the following description, in connection with the accompanying drawing. is a specification. like characters on the like parts.

This invention 're ates to thread parting mechanism employed on automatic fillingrc ilenishing looms to sever the old or spent filling adjacent the shuttle. upon a change of tilling, the filling thread being parted and clamped by a suitable device and while clamped the severed pit-cc is hrougl", into positlrm to be out adptcent the cloth lay a temple thread-cutter. Looms so ecuipped are well known in the art, and United States Patent No. 701,988 granted June 10, 1902 to Roper is one example of such a structure, and means is therein shown for catching between jaws the severed piece of thread and gradually working it forward and out of the way. This is to prevent such iec'e of thread from being caught bv the fresh riding unit carried by it into the cloth.

a my present. invention the con-mined thread pnrter and clamp is bodilv movable into position to act upon the old or spent filling adjacent the cloth, and between the parting and clamping device and the edge of the cloth I provide a novel thread-removcr comprising a fixed support for the severed piece of thread and a cooperating, intcrmitting'y rotated brush ,to sweep the severed pieces forward on the support and out of the we" of the fresh filling.

The novel eatures of my invention will be fully described in the subjoined specification and particularly pointed out in the following claims.

Figure 1 is a transverse sect ion of a portion of an automatic fillin -replenishing loom provided with threati parting and clamping mechanism, and with a thread--- mover emhmlying one form of my present invention; Fig. 2 is an enlarged detail in' side elevation of the thr'ead-remov er; Fig. 3 is a top plan view thereof, also enlarfd.

Referring to Fig. 1 the lay A, llin feeder F, tranafcrrer J, controlling roc shaft 11' turned in the. irection of arrow 50 to eflect filling mplenishlnent, the shuttlefeeler Y mounted to rock-on stud a and also to move laterally thereu n, the arm a'" fast on the rock-shaft d an bearing on the pin 30 on the ahuttle-feeler, and the spring S", may be and are all substantially as in the Roper patent and operate as therein set forth. The combined threadmrter and thread-clamp, indicated as a who e at C, Fig. it, may also be substantially such as shown in said patent, and neither the patter and clamp nor the other part of the mechanism described forms any novel part of my inventiomand as all are well known no further description is necessary. Herein I have retained the upright, stationary arm E, Fig. 1. which forms a part of the thread-catcher of the patent, dispensing with the other parts, the rearwardly extended head c of the curm herein constitutin a. support for the severed piece of thread and serving as the fixed memher of the thread-remover. The cooperating member, in accordance-with my invention, is shown as a brush comprising a huh 1 provided with hriutlzca 2 and mounted to rotate on a horizonta mind 3 between ears 4 of a stand 5 rigidly mounted on the breast-beam B of the loom and extended rcnrwordly above the sup )ort a, so that the bristlco oi the rotatable rush will sweep ow the top of said support. A circular ratchet 6 is 2:2- cured to one end of the brush hub,tobe acted u mn by a awl 7 formed on the rear end of e nt paw -carrier 8 having a. slot 9, Fig. 2, to receive the stud 3, a spring 10 between the stud head 11 and pawl-carrier priming the 9 letter against a boss 12 on the outer side of the adjacent ear 4. The front end :of the pawl-carrier is pivotally connected with one end of a lever 13 fulcrumed at 14 on the stand 5, the other end 01? said lever being connected by a link J15 with the pin on the shuttle-feeder Y, as shown in Fig. 1.

When filling rcplenislnuent. is called for the rock-shaft d is'turn l in the direction of arrow 50, Fig. l. and t to sliuttle-l'ecler Y is swung rearward on its fulcrum a to o ratively maition the thread parter and c amp C to act upon the old filling thread and part and clam it near the shuttle. the shuttle-fee er swings rearward the pin 80 rises and through link 15 the lover13 is rocked to do rem its rear end, thereby rockin the raw merrier 8 to elevate the pawl 7 am onal ile it t tat-1c hold of a new tooth of the ratchet (3, the slot 9 permittingsi necest ry sliding motion of the pawl-carrier on the etutl 3 at such time. The spring 10 fit-l lo I the pawl clicks over the ratchet teeth. and when the shuttle-feel" returna to normal position the lever 13 and pawl-catirier ts are returned to the position shown, thereby eti'ecting a per-ml rotation of the brush in the direction of arrow 6Q, Figa. 1

so that they etlnnot be caught by the fresh filling and woven into the cloth. To prevent undue freedom f movement of the hru h a friction spring 16. Fig. i.-' provided. mounted on one of the enr. l and tearing again-t the adjacent end of the brmh lull: l.

The shuttle-feeler he. as lateral as well as a rocking movement on the stud u and the pin 20 partakeof these movement.-. .-.o that the link 15 is loosely connected with the pin,

nnd by a guide 17 the link is h ld from improper f-"lL' lH! movement. the guide being fixed on any part of the loom frame.

After the severed pieces of thread are swept forward by the )ru-h to n ptmtion in front of it the -hn'tin" or jarring of the loom soon causes them o drop ff the support while they annot movelm kward thereon on account of the bruab.

The structur is -imple and etl'e 'tiv and the wear is eompar-itivelv slight. inasmuch as rotative mm-en'iem of the bru-h is effected only when filling i:- replenished.

Having fully described my invention. what I claim as new and de-xire to s cure by Letters Patent is:-

1. In an automati tillingreplenishing loom having: a d vi -e to part and "lamp the spent thread of filllht. "pm. tilling replenishment. and means to actuate uiddevice. in con'ibinntion. n fixed suppor. for the -evered piece of thread. a rotatable member to sweep the -ev -ted pi ce of thr ad frontwurd alontqthe supp rt. and m ans to efl'cvrt intermittent rotation of aid member.

'2. in an automaticfilling-re :lenishing'. loom having a thread-parting and clamping device bodily movable upon filling, replenabandoned. in combination.

: of lillin to r. thread-removacomgiaing a tired sup- (or aavcrcd member iece e a cobperating, intermittent y rotatable member to am the icon ct thread I tctrward along the men and means to elect rotattvo movement of the rotatable member when filling ia re leniahed.

8. In an automatic ing-re lcniahtng loom havi a thread parting an clamping i device bodt v movable upon fillinfiereplenishment into position to act upon t thread 3 of filling to be abandoned, in combination, a thread-remover comp a support for the severed piece of t d, a rotatable brush mounted above and to awcep the upper face of the aupport. and mcana to cflect rotative movement of the bruah to thereby on the aupport.

In an automatic filling-re lcnishing loom h'avin a threcd parting an clamping device hodi y movable upon tillit'ig repleni.-hment into position toact upon 0 thread of fillinf to be abandoned. and operating means or said device, in combination, a fixed support for the piece of thread severed by the rting device. a rotatable brush to sweep the severed piece of thread frontward along the support. actuating connections between the brush and said operatin means, to eflect intermittent rotation of t e brush when replenishment of filling takaa place.

5. In an automatic filling-replenishing loom having a shuttle-feeler, a thread parting and clamping device thereon bodily movable upon filling replenishment into position to part and clamp the filling thread to be abandoned. and means to govern movement of the ehuttlefeeler, in omnbination, a thread-remover comprising a substantially horizontal. stationary thread support adjacent the shuttlc-feeler path, n coil rating, rotatable brush having an attac ratchet, u pawl. is pivoted carrier on which it is mounted. and actuating means for aid marl-carrier. connected with and operated by movement of the s huttle-feelcr into and out of operative itt on, to eflect. intermittent rotation of t e brush.

In testimony whereof. I have signed my name to this specification in the presence of two subscribing witnesses.
