Specification of Letters Patent.

Patented Jan. 16, 1912 Application filed June 22, 1910. Serial No. 568,290.

6 all whom it may concern it known that I. Joxas .\oRTunor,-a

citizen of the United States. residing at Hopedale, in the county of \l'orcester and State of Massachusetts. have invented an Improvement in Filling-Replenishing Looms,

' .of which the following description, in connection with the accompanying drawings, is a specification. like letters on the drawings representing like parts.

v.The invention to be hereinafter described relates to looms and more particularly to looms of the filling replenishing type, wherein at times a fresh supply of filling is furnishedautomatically. Inthis type of loom ii 'uchtrouble has been experienced in properly controlling the-end of the filling threads leading'fromthe carriers in the supplying means. 'On 'the one hand, the ends of the filling threads must be held'at some point in order-that filling be-laid by the shuttle on the firstpick a t er replenishment and the Shuttle be threaded automaticallvthe "otherhand these ends are liable to be caught which they have been wound. but regardless of whether means were provided to take care of any slack occurring between the carriers in the supplying means and the stud, these thread ends when severed ator near the selvage would dangle in the path of the lay or ioker stick with consequent liability of bemg carried or thrown into the shed. Another serious objeetion resulted from the constant accumulation of waste ends about the ,stud in *that it required to be cleaned frequently, and often before the operative would get around to'clean the stud; itbecame so clog ed that the new thread ends wound on it w en the supplying means was refilled would not remain in pjroperposit-ion, thus causing misthreads when the filling. carr iersweretransfe'rred to the shuttle. These troubles have becomeso "serious in some mills, particularlythose using coarse filling, .that many attempts have been made to over come them, butwithout success.

objects of the invention will best be made clear from the following description and accompanying drawing of one form of means for carrying the invention into practical effect-it being understood that in matter of details the invention may take many forms and that other means than those shown may be employed to carry the invention into effect within the true character thereof as defined by the claims.

In the drawings :-Fi'gure' 1 is aplan view of one end portion of a loom embodying one form of the invention. Fig. 2 is an end view at the filling replenishing side of a loom containing the present invention, only 'so much of the loom being shown as is necese.-. a

sary to properly indicate .the association of the invention therewith; Fig. 3 is a detail sectional view on the line 33. Fig. 1: Fig. 4 is a like sectional view on the line p-4, Fig. 1: Fig. 5 is a sectional view of the thread take-up and one form of means for retiring a thread after it has been severed from its carrier: and Fig. 6 is a top or plan view of the shuttlebox at the fillingreplenishing side of the loom.

The com frame 1 may be of'uny usual or desiredcharacter 'to which is securedthe bracket 2 by suitable means. such as the bolt and nut said bracket having in the present fornrof the invention a web 4 acting as one of the-supports for a filling carrier su'p plying nieans or hopper 5. Sustained by a bearing 6, Fig. 1, is a rod or stud/Z secured by. bolts 8, 8, or other appropriate means, and affording a support for a web 9 which may sustain a part of the hopper 5-: The hopper may obviously be supported in any manner desired. the webs 4 and 9 constitut-.' ing only one of the various means which may be employed/ The hopper 5 is preferably of the character shown; wherein filling carriers may be 'sustained in staggered or plural line formation, although features of the present invention may be employed with other types of filling supplying means. At its lower portion the-hopper 5 is provided with a throat 10, Fig. 4, through which the filling carrier 11 may be forced by a transferrer'12, Figs. 1 and 4. This transferr'er may be of any desired character, its function being to force a filling carrier 11 through the throat l0 and into a shuttle atdesired times. In the present representation, the transferrer is shown as mounted on the stud or rod 7, Figs. 1 and 2, and provided with an arm13, Fig. 2, which, when the filling is to be changed, may be actuated in a manner well understood by those skilled in the art, and substaiitially as pointed out by my prior application Ser. No. 516,240. If desired also a filling carrier ositioner let, Fi 4, such as fully describ in my said app 'cati on or otherwise, may be employed to move a filling carrier into position forpassage through the throat 10. The throat has a fixed front wall 15, and a movable back wall 16, the normal dimensions of the throat being too small to permit assage of a filling carrier therethrough. n order, however, to permit a carrier. to pass through the. throat when forced downward by the transferrer, the back wall 17 of the hopper is mounted to yield. This yielding action is preferably secured by forming a lug 18 on the back wall of the hopper and pivotally mounting the lug at 19, Figs. 1 and 4, to a fixed part, such as an end wall of the hopper, so that the back wall may swing about a center preferably near its upper portion.

- The back wall may be normally retained in position as indicatedrby full lines, Fig. 4, thatis in position with the throat l0 closed to the passage of afillin carrier, by means ofa spring 20, Figs. 1 an 4, suitable uiding flanges 21 being provided to guide t e back wall 17 as it is moved. The lower ortion of the back Wall 17, Fig. 4, is turne frontward and if desired may be provided with a guidin notch to engage a lug or projection 22 on t e end frame of the hopper, the construction and arrangement being such that as the transferrer forces a filling carrier through the throat 10, the back wall of the hopper may swing about its pivotal mounting against the tension of the spring 20, and be suitably guided in its yielding action to- Ward and from the front wall of the hopper. When filling carriers are in the hopper, it will be apparent that this back and forth moyement of the backiwall will serve to agitatesuch carriers sufliciently to insure their properfmovement toward transferring osition and their passage into single line ormation in the lower part-of the hopper.

the

.rests upon the l 1 and 2.

' As thefilling carriers move downward in the hopper; toward transferring position, it

is ap arent that slack will be produced in ling ends if the terminal ortions thereof are secured or held at a point in a plane near the lower poron of the hopper; and slack may sometimes occur in the individual threads by unwinding from the individual carriers. The present invention, in addition to meansfor taking up such slack either in the series of filling threads or-in any individual threads, -contemplates means for separating or retiring any thread end that may become broken or severed, as for instance after a transfer when the filling end is out or broken at or adjacent the cloth selvage, and as one meansto these ends the following has been devised. Mounted on the rod or. stud 7, Fig. 1', is a bracket. armor support 23 'havin 8 lug or'fing'er 24 which arm 23'has a rojecting portion 261 h; which} is provided a aring r'a shaft litend ing through the web 9 and carry' at its outer'end rtion the take-up wheei i he take-u wheel 28 is. preferab y providd with ayielsing surface which may 9 appropriately be formed of felt, cloth,- or, other suitable material. In cooperatingire-i lation with the take-up wheel 28 a 29 mounted 'on an arm 30 which r-gfl tion 31 hearing in the bracket iii-1x123,

1, 2 and 5, the rtion 31 of said arm,- conveniently rmed (with. a a against which acts the spring 33, tffchnstruction being'such that the 3 ring 381201" mally. acts to force the whee 29;into '00- 1 0 acting relation with the take up wheel 28. Extending from the bracket arni 123*is the thread guide and separator 34, over which the filling ends 35 pass from the fillin carriers 11 in the hop er to the bite' between the take-up w eel 28 and ft-he wheel 29. The thread guideand se'iii'ator curved about the take-up wheel' 8-0 that the series of thread ends' lea from the 1 carriers to the take-u wheel mayr'be held in separated and sprea relatiomjs shown in Fig. 2. From the thread 'guide and S6P&-' rator 34 the spread and se arated threads 35 pass about the take-up w, eel 28-between it and the wheel 29 and then pass over another guide 36, Fig. 2. -i By the construction thusfardeseribed it will be apparent that thethreadsdo notpass between the take-up rolls in a bunched relation but'maintain (it libstanti'all separated or spread conditi ;t hat t is condition may be furthe tained b the guide 36. From the" fi ",SG-the t ead. ends .35 ma pass abouta-guide 37 1 Figs. 1 and 2, sai guide 37 pro ecting o'm' the. arm 23 and being itselfconnecte to an arm 38 projecting from the spreader guide 'or other stationarysupport, the construction being such that-{the threads, after bein spread by the" 36,, are bunch together at the union between the guide 37 l the take-up wheels 28 and wheel '29 will, be and part 38, said part 38, while forming with the guide. 37 a receiving notch at their junction. has its end portion extended downwardly somewhat. as indicated in Fig. 2.

Projecting below the take-up wheel 28 and the wheel '29 is a deflector 39, Figs. 2 and 5, the edge portion of which, see. Fig. 5, projects beyond the plane passing through the end faces of the takeup wheel 28 and wheel 29. The derlcctor 39 may be of any usual or desired character, but is herein represented as extending from or between the lower part of the two guides 34: and 36,

though, as will be obvious, it may be vari-' ously formed. From the Construction dcscribed, regardlessof the particulars thereof, it'will be apparent that, if a filling end beoomasibroken and hangs downward. as

indicated in Fi 2' and 5, such filling end willpass over t e edge of the deflector 39, and as the wheels 28 and :29 rotate, as will hereinafter appear, such deflector will cause the severed end to pass from between the nip of the wheels 28 and 29 and drop downward, where such ends may be finally collected in a suitable receptacle, if desired.

As a means for causing rotation of the take-up roll 28 and perforce its coacting roll 29, the shaft 27 has secured thereto inside or the bracket 9, Figs. 1 and 3, a ratchet wheel 40, the ratchet teeth of which are adapted'to be engaged by the end of a pawl ferrer moves in transferring a carrier from the hopper to the shuttle, the lower one of these lugs will more downward and permit the arm 42 to drop downward and substantially in the line of the upper surface of the shuttle box, and, as the transferrer rises after a transfer, said lug will lift the arm 42.into its upper. position again.

by Figs. 1 and the 'transferrer has the lugs 43, 44, between which is disposed the lug 45 of the arm .42, Fig. 1. the action of such parts being substantially as indicated in said prior application. From the con st-ruction thus described it will be apparent that when the transferrennnoves down in transferring a carrier from the hopper to the shuttle, the arm 42 will be lowered'and the pawl 44 will more over the ratchet 40 into engagement with the 'next ratchet tooth, whereupon, by upward movement. of said arm 512 as the transferrer returns to initial position, the shaft 2'? and perforce caused to rotate to take. up both collectively and individually the slack in the'iilling ends leading from the filling carriers. In order that the ratchet 40 and the shaft 27 may not be turned in reverse direction, there is pro vided a holding pawl-'48, Fig. 3, which, as the arm 42 and pawl ll move down to their lowered position, will hold the ratchet 40 from rotative movement but permit such ratchet to rotate contra-clockwise when the arm 42 and pawl 41 return-to initial position. Suitable stops 47 and 48 may be provided to limit the movement of the arm #2, and the stud 49 may sustain the pawl ll from dropping too far to the left when the arm 42 is lowered.

The tip ends ofthe fillingcarriers, as indicated in Fig. 3, are supported by arib 50 formed preferably as a part of the hopper. but when the filling carriers are moved in Fig. 3, and the coacting surface of the I tilting arm 51, pivoted at 52 and normally sustained in position indicated by means of a spring 53.

It. is essential at all times that neither the lay nor the picker stick or other moving partcatch upon any of the filling threads which extend'from the. hopper to the akeup or filling end controller, and as a. further means to this end the present invention provides an arm 5-4, Figs. 1 and 2, which will sustain by its upper surface any sagging thread as it approaches the plane of laying movement.

After a filling carrier has been transferred, it is important that the filling end which extends between the take-up wheel and the shuttle before it is cut or broken at the selvage of the cloth be not caught by any part connected to the lay, such as bolt heads and. other projections thereon. To

this end the front wall of the shuttle box is In the I present form of the invention. as best shown provided at its upper portion with a guard 55. Fig. 6, extending longitudinally of the shuttle box and preferably overlying the bolt head or other rejection 56 or other projecting part 0ft e shuttle box. At .its inner portion, that is at the portion nearest the fellof the cloth, the guard 55 has rim 57 which further serves to protect the filling tluead'from being caught by a moving part connected to the lay.

As the lay moves back after filling replenishment and the shuttle is picked to the opposite side of the lay, the filling end extendmg from the shuttle, if not properly guard-- ed. may catch upon the hunter to guard vv'r Ich there is provided a guard piece 59, the

'50 transfer fil front edge ortion of which extends down:

ward, as indicated in F ig. 2, and effectively prevents the filling end rom injurious contact with the hunter.

i After the loom hasoperated one or more following filling replenishment, the

icks filling end, still held between the take-up roll and roll 29, is severed or'broken at the selvage, whereupon the severed end drops downward, as indicated in Fig. 2. As the lay moves back and forth, this end portion of the filling end is liable to be caught in the shuttle box or to become entangled -there with the. shuttle .or the pickingdevices and to be carried into the shed. To guard against this, during the time that the deflector 39 is acting upon this filling end to retire it from between the wheels 28 and 29, there is secured to the lay a plate 60 having an inclined portion 61 adapted to deflect the I filling end toward the outer edge 62 of the plate and the shouldered portion 63,-Fig. 6,

the construction being such that after the end has been broken or severed at the selva such broken or severed end portion will and ride over the incline 61 to the outer edge- 62 of the plate 60 where it .will graduall move outward as the deflector 39 retires t e threadifrom between the wheels 28 and 29, as will be readily understood.

It will be apparent that many changes may be made in the details of; the present invention without departing from the gen; eral character and spirit thereof, and it 18 to '6 be understood that the invention is not re stricted to the articular means herein shown and descr bed as one embodiment thereof, but that it is definitely set forth in its true scope by the claims.
