Application led May 4, 1915. Serial No. 25,710.

To all whom it may concern;

Be it known that I, ALoNzo E. RHoADEs, a citizen of the United States, residing at Hopedale, county of Worcester,- vand, State of Massachusetta have 'invented an Im provement in Filling-Replenishing Looms, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

The invention to be hereinafter described relates to filling replenishing looms, and more particularly to the means for preventingdthe ends of filling being carried into the she f In looms of this general character, 'when replenishment of the filling is effected, prior to the complete exhaustion of the filling in the running shuttle, there is an endl of filling leading from the outgoing filling carrier to the cloth selvage, which is generally denominated the old filling, and there is another filling end leading from the fresh filling carrier to some securing means where the end of the new filling is secured, and such length of filling is generally denominated the new filling end.

Various attempts have been made with more or less success, to prevent the old filling end from being carried into the shed after a replenishing operation, and some efforts y have been made to' effect a similar result with respect to the new filling end. In all these latter attempts, however, the new filling end has been parted at a point so far from the place where the end of the new filling was secured, thata long end of new filling dangled from the securing means and was liable, duringwv the back-and-forth movement of the lay, to be caught by the shuttle or vthe working filling, and lbe carried into the shed.

With the above generally-stated facts in mind, the aims and purposes of the present invention are to provide means whereby the new filling end may be parted at such point of the operating parts, or bythe working filling, and consequently cannot be carried into theV shed. Another important feature of the invention in connection with the part- A ing means referred-to, the provision be- Y that the details may be vari tween thev selvage or temple thread cutter and -said parting means of means for carry-- ing out of the loom the piece of new filling after it has been parted. from the securing means and the cloth selvage.

A further purpose of the present invention is to provide parting means' for the new filling end which shall be setlfor. action only upon call for filling replenishment, and shall thereupon part the vnew filling on the' for-i ward movement of the lay subsequentto the replenishing operation.l

- The present invention also embodies other.

important features, all of which V will be more fully understood from 'the following description and accompanying drawings of one form lof means for carrying the invention into practical effect, it bein understood ed within the true scope of the actual invention. In the drawings g Figure 1 is a view looking toward the end.

Fig. 4 a perspective view of parts at the filling" replenishing side of the loom showing. Ithe hopper, the securing means for the ends of the new filling, the parter, and associated elements, some of the hopper v stand or bracket being broken away to dis-fy -close parts beyond.

The frameof the loom may be of any suitablecharacter' for supporting the operating parts, and as shown comprises the usual standards or uprights 1,l and .breast beam 2.

The filling replenishing mechanism may be of anyusual or desired character, but as herein shown, it comprises the hopper stand or bracket 3 rising from a base plate 4 which may be secured to the breast 'beam 2,as by suitable bolts ,5. Pivotally mounted at 6 upon the usual supporting stud is the transferrer 7, the end 8 of which is adapted to engage a filling carrier 9 mounted as usual in a rotary hopper-10 supported by the hopper' stand or bracket 3 as usual. A. portion of yone end of the hopper is shown at 10,

Figs', 1 and 3.- Depending from the transferrer 7 is the arm 11 having the dog 12 piv.

otally secured thereto, as usual, and adapted when in raised position'to be engaged by a suitable bunter 13 carried by the lay to cause the transferrer to transfer a filling carrier from the rotary hopper to the shuttle in the shuttle-boxbeneath and by such action also, to eject the spent or practically-exhausted filling carrier. v

The positioning of the dog 12 is effected from the ltransverse shaft 14, Figs. 1 and 4, as the'latter is rocked by well -understood mechanism when the usual indicator indi` v cates substantial or complete exhaustion of filling in-the active shuttle. The arm 15, the spring 16, the arm 17 pivoted at 18 and o having a finger 19 and the connection of the arm 17 with the dog 12-as at 20, may all be `as usual, and since such parts and their operative relation are well understood by those skilled in the art, further elucidation herein is unnecessary.

One of the purposes of the present invention, as hereinbefore indicated, is to part' the new filling end at such point that the portion thereof which extends-from the securing means for the end, cannotbe engaged by any of the operating parts and be carried into the shed. To this end,-it is within the contemplation of the invention that the parting means for the new lling endv shall part such filling end after a filling replenishing operation at a point nearer to the securing means for said end than the distance between the said securing means and the lay or shuttle-box. Under these yconditions, it will be' apparent that the end whichis held by the securing means after the new- .filling has been parted, cannot reach any of the operating parts, and consequently, danger of its being carried into the shed is entirely overcome. The part of the new filling between the cloth selvage and the point at which it has been parted, as hereinbefore noted',` is subjected to the action of a controlling means such that as soon as the new A filling has been parted at the point designated, the loose end leading from the cloth selvage is at once drawn away from the operating parts of the loom and when such `loose'end is parted from the cloth selvage, it is bodily carried outl ofthe loom, or away from all danger of beingenga'ged and car-A ried into -the shed. v

ln carrying the invention into effect, the

parting means is formed of .two relatively' l movable members which are preferably maintained in closed or.. inoperative relation during the normal operations of the loom,

andare separated or placed in position for' performing their parting function upon call for filling replenishment.

In carrying this feature of the invention into effect, the hopper stand or'bracket 3 is 70 provided with a guideway 21 extending from the front toward the rear portion of the hopper stand, as indicated in Figs. 2 and 3, and in said guideway 21 there is mounted the parter operating member shown herein as a rod 22 Figs. v2 and 3 extending toward the rear of the loom in the guideway 21 and having'secured to or formed as part',l of its rear end portion, a parting or cutting memf ber 23, Figs. 1 and 4. `This parting or cut- 80 ting member 23 is preferably slotted, as at 24, Fig. 3, to straddle the stationary part-Y ingor cutting member 25 Figs. 1 and 3 when the .cutting member 23 performs its parting stroke, as will hereinafter more fully appear.

' The'stationary member 25 of the parter is'preferably formedA as a lplate secured by appropriate means such as the screws 26 in l. a' recess or cut-away portion of the hopper 90 stand 3, Vsubstantially as indicated in Fig. 3, the construction being such that when the panting or cutting member 23 moves to the front from the position indicated in Fig. 1v, the stationary member 25 will enter the slot 95 24 of the member 23 and the new filling end a will be parted,V as will readily be apparent from Fig. 1.

Extending downwardly from the rod 22 isA a head 27, Figs. 1 and 4, having a facing 100 28 of yielding material, such as leather, rubber, or the like, to be engaged by a bunter 29 carried by 4the lay. The head 27 is normally under the influence of a spring 30 which tends to move the rod 22 and its at- 105 tached parting member 23 rearwardly, when said rod and parting member are free to movement. This spring 30 may preferably be seated in a recess 3l formed in the hopper stand, one end of said spring being seated upon a wall at theend of the recess 31 andL the other end of'the spring against the head 27, substantially as indicated in Fig. 1, the construction being such that the spring 30 normally acts upon the head 27 to project it 115 andthe connected rod 22 and the parting member 23 toward the rear of the loom.

The rod 22 is provided with a notch 32 near its outer end, ,adapted to be engaged by a latch 33 pivoted at 34 Fig. 2 to the 120 base portion 4 of the hopper stand, a spring 35 .normally acting upon the latch 33 to move it into engagement withthe notch in the ,Jrod 22, the construction being such that when the rod 22 ismoved toward the front, 125 of the loom and the movable member 23 of the parting device is moved toward and into coperative relation with -the fixed member 25 thereof, the latch 33l will drop into the recess 32 of the rod 22 and thereafter main- 130 tain the rod and its attached movable member 23 toward the front of the loom.

The condition of parts described is that which4 they maintain during the normal operation of the loom, that is, while a sufficient supply of filling is present for weaving purposes; and it will be noted that the fixed and movable members of the parter are then in closed relation, substantially as indicated in Fig. 3. lVhen, however, a call forfilling replenishment is made, it is thespurpose of the present invention that the fixed and movable members of the parter shall be rela-` tively moved into the position substantially.

as indicated in Fig. 1; and as a convenient means to this end, there is mounted upon 'the transverse shaft 14, a rocker arm 36, the upper portion of which is provided with a lifting cam 37 normally positioned -below the end 38 of the latch 33, the construction being such that when the transverse shaft 14 is rocked contraclockwise, viewing Fig. 1, upon call for filling replenishment, the lifting cam 37 will lift the end 38 of the latch 33 and free the rod 22 to the action of the spring 30, whereupon the latter will move the rod and its attached movable parting member 23 to the rear into substantially the position indicated in Fig. 1.

The extreme front end portion of the rod 22 is provided lwith an incline v39, Fig. 3, so vthat upon frontward movement of the rod 22 after the replenishing operation and the new filling'has beenparted, such incline portion 39 will lift theend 38 of the latch 33 until the arrival of the notch 32 beneath the latch, whereupon the latter will drop into its locking position, substantially as hereinbefore described, it being understood, of course, that the rocker arm 36 at suc-h time will have moved clockwise again tov carry the low part of the cam-37 beneath the end 38 of the latch, therebypermitting the above control of parts.

In order that the latch 33 may be `properly guided and steadied in its movements,

under the' action of the spring 35, and the cam 37, it is embraced by the two steadying posts 40, Figs. 1 and 2, which maybe appropriately secured to =the base port1on of the hopper stand, as 'by screws or other means 41. f

As hereinbefore noted, it is one of the purposes of the present invention that the end of the filling which may hang or dangle from the securing means for the said end.

after the new lilling has been parted, shall not be caught by any of the moving parts and pulled from the securing means or broken and carried into the shed.

In effectively carrying out this 'feature of the invention, the ends of the fill-ings leading from the carriers 9 which are mounted in the rotary hopper 10, are secured to appropriate securing means to hold this end Y of the filling as the shuttle is picked after Y the replenishing operation andthe part'4 ing mechanism is located with respect thereto so that after its action, the end of the filling held by the securing means cannot reach the operative parts of the loom, which would endanger its being carried into the shed. A s one' vappropriate and 'good form of' securing meansto this end, the rotary hopper 10 is provided withra series of spring-actuated securing pins 42, Figs. 1 and 3, which'are adapted to hold the ends- 1) of the new filling extending from the carriers in the hopper. Ordinarily. there will be suilicientslack in the filling-between the securing means, such as the pins 42, and

the carriers in the hopper to permit 'the carj p riers to be transferred to the shuttle without breaking the filling,butfin the present instance of the finvention af guide or delector 42, Figs. 1 and 4l is provided on the hopper adjacent each llingcarrier in the hopper. 'The filling from the carriers may be Apassed over'the guide or deflector 420 near the tip end of the filling carriers in the hopper, thenlabout the guide or de-. Hector 420 near the base of the -iilling carriers or itmay be passed about only one of these guides or deflectors and then secured to the pins or other securing means 42 mounted on the head of the rotaryhopper; In either case the -g'uides or deflectors insure suflicient` slack thread for the transfer without liahopper or hopper `stand and the top of the shuttle-box. On rotary movement of the hopper .1Q tobring a new carrier into transferring position, the severed end b of the carrier just transferred will be withdrawn st ill` farther from :the shuttle-box,

and this of course, will continue as the hop.- i

per further rotates.

From 'the construction described, it will be noted that upon call for filling replenishment, the rocker arm 36 will be moved contraclockwise into the position indicated in Fig. 1, and Willlift the latch 33 from' locking engagement with the rod 22, whereupon the latter, under the action of the spring 30, will be moved rearwardly, thereby separating the fixed and movable members of the thread parter into the positionl indicated in Fig. 1. After the replenishing operation, thelay moves backward and the shuttle is picked to the opposite box, whereupon the/end of the new filling leading from the securing means or pins 42 and under the hopper stand, will bel drawn into the space between the fixed and movable mem- .bers of the 'thread parter, and upon the next forward or beatup movement of the lay, the head 27 secured to the rod 22 will be moved by the bunter 29; frontwardly,

thereby closing the movable and fixed members of Ithe parter and parting the filling in the position indicated at a, Fig. l. Thus 'filling replenishment.

forward movement of the .movable parter 23 and its connected rod 22 positions the notch32 beneath the latch 33, so that after.

this beatup movement of the lay and parting of the filling as described, the fixed and movable members of the parter will re main in close relation until another call for The vnew.` filling having been parted in the manner described, it is desirable that that A portion of the filling leading'from the cloth f selvage which still remains intact, shall not be drawn into the shedby the shuttle on asubsequent'pick; and to this end there is.

mounted upon the breast beam, the pneumatic illin end controller 43 which may be of substantlally the same character and construction as that described in a priorap-v f plication filed by-me October 297 1914, Se-

rial No. 869,206. In the present invention, however, the tubularportion 43 of the pneumatic controller is provided with an end rest 44 having a turned-up or lip ortion 45 at the end, so that when the plece of y' filling c, Fig. 3, has been parted between .the hopper and shuttle-box, as hereinbefore described, it will drop upon the end rest 44 and by the ingoing air currents'be sucked..

into the tube 43. In order that the rest 44 may project sufiiciently far rearwardly towardv the lay 45", said lay is providedwith a'groove portion 46 extending transversely 45.

thereof, .substantially as indicated in Fig. 3, the construction being such that as the la beats up, the portion c ofthe new filling l a' er it has been parted between the top of the shuttle-box and the bottom of the hop- -per stand, will drop upon the rest 44 and be unerringly carried into) the suction tubey 43 by the ingoing air currents. t

When the portion c ofthe new filling is thus engaged by the filling end controller 43 and held therein, by the air'currents as described, it will be positioned for the acthe lay, will, sever the new filling atthe tion of the temple thread cutter 47 which, upon a subsequent forward movement of cloth selvage and permit the parte, .now

' bodily free, to move into the controller 43 A and be carried out of the loom. It will be noted from the construction descrbed as a convenient form or'embodimet *of the present invention that the new filling end is `parted above the shuttle-box, the

front /wall 46x thereof being indicated in Fig. 3; and that the severed portion b will .not be in position forengagement by the shuttle. It will also be noted'that the`loosel portion c, Fig. 3, will at once be brought under the control of the filling end controller 43 and will be drawn by the air currents thereinto, until the selvage'or temple thread parter has acted, whereupon the free piece of filling e willbe carried out ofthe loom.

I'n order that the movable and fixed mem bers ,23 and 25 'of the 'parting mechanism shall be limited in their degree of separation, g

a stop 48 may be provided at the end of the guideway in which the 'rod 22 is movable,

` so that the head 23 ofthe movable'member It will be evident, ofcourse, that changes I parting the new filling in such position with yrelation to the filling end securing vmeans that the end extending from the securing means cannot be reached by any of the parts liable tol carry theshed.

In the present instance of the invention, the filling'parting means isillustrated adjacent the buttV ends of the filling carriers in the hopper, and such disposition of the parting means and securing means has been found in practice to be well adapted to the intended purpose, but it is to be understood, of course, that thisA location of the parting -means and securing means is not essential. and they may be otherwise dis osed relative to the filling carriers, as wil belearly obvious to those skilled in the art.
