THREAD PARTER AND CLAMP.

Application led January To all whom t may concern.'

Be it known that I, ALONZO E. RHoADEs, a citizen of the'United States, residing at Hopedale, inthe county of Vorcester and State of Massachusetts, have invented an Improvement in Thread Parters and Clamps, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

' This invention relates to thread parters and clamps for use in filling replenishing looms.

It is now the general practice to provide filling replenishing looms withA a shuttle feeler having associated therewith a thread parter and clamp for parting the filling between the shuttle and cloth selvage when filling replenishment is effected and positioning the end of the llling leading to the cloth selvage for the action of the temple thread cutter. 'Ihe shuttle feeler thread cutter or parter is now ordinarily formed of a fixed and a movable member, the latter of which is actuated by the lay when the shuttle feeler is in its rearward shuttle lfeeling position, and mounted on the shuttle feeler at the side of'the thread parter there is usually a thread cla-mp between which and the movable thread cutter or parter the thread end leading to the cloth selvage is yto be clamped and held, so that when the shuttle feeler returns to its frontward position the end leading to the cloth selvage will be presented to the temple thread cutter.

As heretofore ordinarily constructed, the thread clamp and movable member of the thread parter have been arranged face to face, that is, the side of the thread parter bore against the side of the thread clamp, with the result that when the parter was actuated to part the thread, the end of the filling leading to the clothl selvage would fail to be clamped between the parter and clamping member. or the movement of these members past each other during the kclamping operation would causel breakage of the thread at the clamp and consequently the end of the filling leading to the cloth selvage would not be positioned'for the action of the temple thread cutter.

One of the objects of the present invention is to provide a thread parter and clamp wherein a space is provided between the side faces of the parter and clamp to r6- 15, 1925. Serial No. 2,573.

ceive the end of the filling and thereafter clamp the filling end by movement of the parter and clamp relatively in a lateral direction to pinch the thread between them.

In accordance with the present invention, the clamping member underlies the thread leading from the shuttle to the cloth selvage when the shuttle .feeler is in its rearward shuttle feeling position, and upon actuation of the parter to partthe thread the clamp itself is moved in an opposite direction to lift the filling end that it may be clamped between the parter and clamping member before the filling is cut or parted. Y

The invention and novel features of the structure will best be made clear from the following description and the accompanying drawings showing one good form thereof.

Fig'. 5 is a section on the line 5 5 of Fig. l.

The shuttle feeler may be of any usual character and mounted for movement into its rearward shuttle feeling position on call' for replenishment ofiilling. As'shown, the loom frame has'secured thereto a bracket 1 which may be adjustably mounted onv the 'loom frame by a bolt 2 entering a slot 3 formed n the bracket member. The shuttle feeler 4 is shown as mounted for rocking movement on a stud 5 extending from the bracket 1 as usual in this type of shuttle feeler, and extending from the bracket 1 is a guide 6 for directing the movement of the shuttle feeler as it is turned to and IQIX! its shuttle feeling position,

Extending from the shuttle feelei ll-is a pin 7 which is engaged between the two arms Sand 9 for moving the shuttle'feel'elr to' and frbm' its; 'rearward position, usual in this type of" mechanism, The arms 8 and 9 are connected to the transverse or rock shaft (not shown), but since such Vdetails form no essential part ofthe present invention and are now well uiiderstood'in the' art, they' are not-hereinafter described. v

The shuttle feeler l has its end portion 10 extending rearwardly d and isl provided with the-usuall opening,` 11 for engagement with the' shuttle, Yprovided thev latter is not properly boxed, and securedto the inner face of the end Vportion 10 of Vthe kshuttle feeler is the lixed threadpart'er '12, which may be conveniently formed as a blade'secured as usual to theshuttle feeler. The cutting edge portion-Hof the fixed blade 12 is shown `as slightly below vthe surface 111 y"of the shuttle feder, on whichthe filling end a is supported when tlie shuttle feeler is in its rrearward feeling position. y I A "'Pivotallymounted on thepin r15 extending laterally from the end l0 of the shuttle feeler istheimovable threadA parter 16, the frontwardly extending end portion of which is provided with an actuating member or toe 17 -`which -isadapted tobe sti'uclrby thejlay or a,1 lpart f carried1 thereby, to actuate the movable member of the parterto part the thread a between theshuttle 18 and cloth Aselvage.

A I

The threa-'dparter 1.6 has a rearwardly extending end portion A24 which Aunderliesthe thread a -when the shuttle feeler "with V the thread parterand clamp are moved to rearward ^fi"1nction-ing position. v

The 'clamping member 19x is provided with. aslot Q5 into which extends a pin 26 projecting from the movable thread parter 16,

the construction being such that when the thread parier 16 1s actuated, as hereinbefore described7 it `will impart to the thread clamp 19 movement in an opposite direction,

to therebylift the filling thread a as the threadf parjter V'is actuated. y

1f'n accordance 'with the present invention, the thread parter and clamp have a relative lateral movement to first provide a space betive movement of theparterand clamp until the thread tobe partedandclamped has been placed' in a'spa'ce between'the parter 16 'and the clamp 19.

In the present instance of the invention, as

indicated in Fig. 5, the clamp 1,9 is provided with a spacer 29 which i'iorinally: b'e'ars'upon the face ofthe parter 16 and 'maintains the partei1 16 and clamp1f9'i'n separated relation Ytoy provide 'a space 30 betweentl'ie'm for the reception ofthethread to be partedand Pf clamped, and 'to permit the parterand clamp to be moved relatively in Aa lateral direction to clamp thethread when, once'it has been placed in a space between theftwo `and preferably before the thread lis parted, tlien'iovf' ableI member 16 ofthe part'er is VVprovided with` a recess Blv'lwliich, 'asY the plarter 16 is actuated Itorlpiart the tlireadfcomes opposite v@thespacer 29'and permits rthe parter and clamp to move laterally into` thread pinchingposition, as indicated in Fig. 1. v lie spacer 29 shown as rformed byaliea'died bolt or rivet passed through theclamp 197 as a convenient nieanspf forming the spacer to hold the *clamp andvparter in 'separated L relation during the preliminary entering of thetliread between thet'wo, and the recess 3.1 is shown as formedby a depression 'in' the adjacent .side face of the parter'16, the construction bein'g such that when theshu'ttle feeler is in its rearward feeling position and the filling to befparted is restingr in the recess 11 of the shuttle feeler :and on top of the'underlying portionQi ofthe clamp and .the partei is factuated7 the A,thread will zbe lifted by the clamp19 and vpass freely into the open space/*3Q lbetween .the parter and clampas the parter performs yits parting function5 whereupon, orfpreferably kjust prior tothe parting of theythr'ead74 ther recess 31 of the parter 4will pass infront of Vthe spacer *'29ya`nidl permit relative lateral movement of the Yparter and clamp* to ypinch or them., After the 'ltlii'zead has thus been clamped beween the parter and clamping member' and is securely held, the parter 16 will part the thread by coact-ion with the fixed parter member l2, as indicated in Fig. 4.

By preliminarily entering the filling to be parted in the space between the parter and clamp and then causing relative lateral movement of the parter and clamp to pinch and hold the thread, all liability of the thread being broken between the parter and clamp is avoided and the filling end leading to the cloth selvage will unerringly be moved into position forV the action of the temple thread critter.

Preferably the thread will be clamped, as described, before it is parted, but these two operations may take place simultaneously if desired.

As indicated in Figs. 2 and 3, it will be noted that the filling thread is first located in the space between the parter and clamp, as the former moves in the performance of its cutting function, and that thereafter the relative lateral movement of the parter and clamp will hold or pinch the Filling already placed between them before the thread itself is parted.

The lay 32 may if desired be provided with an opening 33 for the entrance of the end of the shuttle feeler parter and clamp when these members are moved to their' rearward functioning position.

Extending from the front portion of the movable member 16 of the parter is a pin 34 which serves in connection with a swinging trip member 35 to open the parter as the shut-tle feeler moves towards rearward position, and after the parter has been closed and the thread has been clamped, as described, such pin 34 will pass the trip 35 by swinging the latter as the shuttle feeler moves to its front position. y

As indicated, in the present form of the invention the trip 35 is pivotally mounted at 36 on an arm 37 which may be conveniently secured to the bracket 1, as usual in this type of mechanism. The trip 35 has a lateral projection 38 adapted to engage a stop 39 on the arm 37 to limit its rearward swinging movement but permit frontward swinging movement of the trip.
