THREAD- PARTING MECHANISM FOR LOOMS.

Specification of Letters Patent.

Patented Sept. 17, 1907.

Application filed January 16, 1907. Serial No. 362,480.

To all whom it may concern:

vide the running shuttle with a fresh supply of filling.

Such a replenishing loom is, for example, shown in United States Patent No. 529,940, granted'to Northrop November 27, 1894, looms of this type being technically known as Northrop looms. 1

When a change of filling is effected the old fillingend, (that is, the length of filling leading from the cloth to the filling-supply in the shuttleand about to be abandoned,) must be severed and removed in order to prevent it from being carried back into the cloth, or

from fouling the fresh filling inserted in the shuttle.

Means have been provided heretofore to part such filling-end adjacent the cloth by means of a temple thread,-

cutter, and to part it near the shuttle by other means.

In my present invention I have provided means to part the old filling adjacent the cloth, causing the operation of such means positively and definitely at the proper instant, instead of depending on the somewhat uncertain action of a temple thread-cutter. Herein such parting means is operated a second time to part the new filling-end which eirtends from the fillingfeeder or hopper to the cloth after the first shot of the replenished'shuttle, after which second operation the parting means remains inoperative until the next filling replenishment is called for. Ihave alsoprovided novel means to part the old filling-end at the shuttle,- and as will appear hereinafter such parting 0r severance takes place at a point nearly opposite the head of the filling-carrier in the shuttle and about to be ejected. This insures-a very short length of filling to be drawn out of the shuttle eye by the ejectedfilling-carrier,

eliminating any fouling of the fresh filling simultaneously inserted in the shuttle.

The length of filling severed by the two parting means is, inthe present embodiment of my invention engaged by a thread-catcher, conveniently mounted .on the shuttle-feeler, the thread-catcher grasping'the scvcred piece of filling and drawing it forward out of the way as the part on which the catcher is mounted returns to normal position -normal position.

Referring to Figs. 1, 2, 3, 4 and,6.- thefilling-ieeder The opening and closing of the clamping members or jaws of the thread-catcher is effected automatically at the proper times.

The various novel features of my invention, one

practical embodiment whereof is illustrated in the accompanying drawings, will be fully described inthe subjoined specification and particularly pointed out' in the following claims.

Fig. 15 is a similar view but showing the blades or cutters as having closed to part a filling-end, and in readiness to be retracted or restored to to hold a plurality of filling-carriers or bobbins b, in-

The tip-support] shown best in Fig. i is of usual con struction and is pivotally mounted on the bracket f X rigidly secured to the outer end of the stud f, and operates in usual manner. I v

In Figs. 4 and 6, I have omitted the tip-support and broken off the stand in order to show more clearly the parts which would be otherwise hidden.

The notched dog m pivotally connected at 2 with the downturned bifurcated extension f of the trans ierrer, the hunter 0 on the lay to cooperate with the dog when filling-replenishment is to be effected, the shuttle-feeler arm y. fulcrumed on a short rocker-shaft i mounted on the loom-side, the shuttle-ieeler arm having a lug 3 Fig. 7, with Which-cooperates the arm 11-, and the arm y having a cam-slot y to cooperate with the lug m on the dog at are all substantially as shown in United States patent to Stimpson No. 718587, dated 7 January 13, 1903, the lower end of the arm 1 being rigidly connected with the rocker-shaft y in any suitable manner. I/

In the present embodiment of my inyention, the 'shuttle-feeler arm g not onlyis arranged to feel for and ascertain whether the shuttle is properly boxed in the box B when replenishment of filling is called for, but

. 1 A it also carries a thread-catcher, to be hereinafter dethe shuttle.

An upturned arm 5 is rigidly bolted at its lower end at 6 to the inner face of the bracket f said arm having an inwardly and horizontally extended pin 7 at its up-. per end, on which ismounted an elongated sleeve-like hub 8, shown as a part of a casting constituting a blade- -earrier, said casting comprising an elongated depending key 9, having a forwardly extended offset 10 to tho apex of which at 11 is attached a spriifg 12, clearly shown in Fig. 4, the lower end of the spring being in turn secured. to a lateral lug 13 on thetransferrer, and

extended L-vlow. the face 14 of the-offset 10.

The blade-carrier is adapted to swing onthe pivot or fulcrum pin 1. reward and from .the lay, and when the transferrer is is normal or retracted position, see Figs.

,3 and 4, the lug 13 acting uponthe iace 14 positively moves the blade-carrier forward into inoperative position.

When the transierrer is operatively moved, to transfer a fresh supply of filling from the feeder to the shuttle, the yielding connection l2 between the transferrer and blade-carrier operates to swing the latter rearwardly into operative position, shown in Fig. 6.

The blade-carrier swings in a path parallel to and near the path of movement of the transferrer, as will be manifest from an inspection of Figs. 1 and 2, and as the transierrer engages the head of the filling-carrier or bobbin to be transferred, it will be manifest that the bladecarrier will move toward or from the shuttle at a point near the head of the filling-carrier therein.

The lower end of the blade-carrier is rearwardly extended at 15, and is provided with a cutting blade 16,

see Fig. 5, to cooperate with a relatively movable blade 17pivotally mounted on a stud 18 extended through the blade-carrier.

The stud is held irom movement in the blade-carrier and at its inner end is enlarged to form a head 19, Fig. 5, and a barrel 20 around which i's'coiled a spring 21.

one end of the spring being attached to the head 19 at.

22, and the other end of the spring is held a pin 23 on an enlargement 17 of the blade. The spring not only serves to press the cutting edges of the blades 16 and 17 together, but also normally 'acts to hold the blades open, tho movement of .the blade 17being lim ited by a pin'24 on the blade-carrier extended through a slot 25 in the enlargement 17 The said enlargement its upturned at its front portion to present a cam-like face 26, and at its rear portion the enlargement 17 is upturned at 27, and provided with a lateral offset 28 extended above the toe 15 and across-the rear face of usual opening for the introduction of the 'feeler in a socalled feeler loom, the opening being near the head of the filling-carrier, and I have herein'shown the front wall of the replenishing shuttle-box B as provided with an opening b so located that when the shuttle is properly boxed lor replenishment, the openings s and b will register, 7 I

The blades on the blade carrier are arranged to move rearwardly into the aperture b when the blade-carrier is operatively positioned, and the lay beats up, as shown in Fig. 6, it being understood that the blades will be open when they enter the aperture and they will remain open until they enter the opening-8 in the shuttle, receiving between them-the o'ld filling-end.-

. It will be understood of course that the old filling-end leads from the eye of the shuttle between the front wall of the latter, and the inner 'facegof the box-walhthehce tejthel eloth at the replenishing side of'the loom, and when the blade-c ier'ismoved into operative position by or through the actuz ition of the replenishing mechanisin, the old filling-end must be brought between the edges of'theblades;

. way portion A of the lay, so that there is practically To those skilled in the art, it will be plain that the lay must move forward from the position shown in Fig. 6, in order to complete the transfer of a filling-carrier from the feeder to the shuttle, a filling-carrier in process thereby turn the blade 17 on its pivot into the position shown in Fig. 6, to part the filling-end. As a matter of fact, the filling-end is parted before the transfer of filling is completed, but the completion of the forward movement of the lay will swing the blade-carrier forward slightly, the spring or yielding connection 12 between said blade-carrier and the transferrer permitting such movement. As the lay goes back and the transferrer f returns to normal position, the bladecarrier is returned to its normal, inoperative position, and the end 4 of the rod 3 acts to insure the opening of the blades, as has been described. As the .old fillingend is parted substantially opposite the head of the filling-carrier about to be ejected therefrom gt will be clear that a very short length of filling will remain to be drawn out through the eye of the shuttle, as such ejected filling-carrier is discharged through the guideno chance for any fouling of the old filling with the fresh or incoming shuttle and absolutely no chance for the old filling to be carried back into the cloth.

If the shuttle-feeler. to be hereinafter referred to prevents the operation of the replenishing mechanism,

the blade-carrier. will not be moved into operative,

position.

The operative positioning of the means for parting the old filling-endfat t-he'shuttle is effected by or through the operation of the filling-replenishing mechanism, as has been described, and the actual closing of the parting members or blades to partthefilling-end is positively effected by or through the lay on its forward beat' at the time of filling-replenishment.

It is necessary to part the filling-end adjacent the cloth at the replenishing side of the loom, and this has been accomplished heretofore by so-called temple thread-cutters and by other devices more or less'positive' or definite in theiraction, but in actual practice these devices have. at times failed to part the old filling endwith the certainty and positiveness which is desirable, and at a definite time.

The parting means embodied-in my present invention for. parting the filling-end adjacent the cloth is controlled as to its operation by or through the actus tion of the replenishing mechanism, and is actuated positively and at a definite time, and I have so arranged the mechanism that it not only parts the old filling-end,

but it also parts the new filling-end'du'eto filling 50, Fig. 1. I The link member 49 extends to. the fight toa bell- "crank 51, 52, mounted to in a substantially liori-- replenishment.

\ Referring to Figs. 1, l2 and 13, I have shown a temple T of suitable construction, mounted on the-breastbeam of the loom at thereplenishing side thereof, the

temple shank having the usual dependi ng heel tto be gated slot 31 in its top, the housing having slidably see Figs. 14 and 15', to the extremity of which is rigidly attached an upper blade 33, a cooperating blade 34 being pivotally mounted on the blade-carrier at 35, and having an upturned lug 36, extended through the slot 3]: A fiat spring 37' on' the blade-carrier presses at its free end upon the pivoted blade 34 and maintains it yieldingly against the cooperating blade 83, to insure proper cutting action. The blade-carrier is provided with a depending heel 38 and isalso forwardly extended topresent a flattened and elongated extension 39 longitudinally slotted at 40 to receive a guide-lug 41 extended laterally from the temple stand T .The extension has an upturned shoulder or abutment- 42, and a forwardly extended, rigid rod 43, slidable in a guideear 44 on the temple-stand. I Between the abutment or' shoulder 42 and the guideear, a spring 44 isco'iled around the rod 43 to move the blade carrier in the direction of the arrow 45, Figs. 12 and 13, when the spring is free to act.

When the blade-carrier is in its normal position, Figs. 12 and 13, and full lines Fig. 14, the two blades are Iretracted within the housing and are open, see Figs. 13 and 14, the opening of the blades being caused by engagement of the lug 36 with the front end of the slot 31 in the housing.

When the blade-carrier is moved rearwardly by the action of the spring'44 the blades willmove out of the housing bodily and in their open position, see dotted lines Fig. 14, until the lug 36 strikes the rear end of the. slot 31, whereupon the blade 34 will be swung upward on its pivot 35 into the closed position, see Figs 15,

such positive closing thereof will part the filling posi- "in Fig. 1 3, and in full lines Fig. 14.

I have provided a detent instrumentality to normally retain the parting means in the position shown in Figs.

12 and 13, and also in Fig. 1, the detent in the presentoperative position byor through the actuation of the "replenishing mechanism.

The temple stand T hasa rigid,'laterally-extended pinyifi behind theshoulder or abutment 42, and upon the piii is slidably mounted a detent shown as a block 47; rigidly attached to one member as 48 of an adjust- .able link 48', .49, the overlapped ends of the two link members being adjustably connected by clamping bolts Zontal plane on'an upright post 53 on the filling-feeder stand, a suitable spring '54 acting'upo'n the bell-crank to normally maintain itin the position shown in Figs.

tively and effectually. If new the. parts are in the position shown in Fig. 15, and the lay beats up, a part a of the latter willstrike the heel 38 and will move the embodiment-0f my invention being withdrawn mm mounted within it the rear end-of a blade-carrier 32,

and if the filling is caught betweenthe open blades,

the parts will thereby be restored to the position shown '1"andI2, with the detent 47 in cooperation with the Y The bell-crank arm 52 is downturned at 53, adjacent to and in front of the depending extension f 3 of the transferrer, so that when the latter is rocked to effect filling replenishment, the bell -crank will be turned in the direction of the arrow 54, Fig. 1, to pull the link 48, 49

to the right, and thereby withdraw the detent 47 from the filling extending from the cloth to the shuttle in -'the shuttle-box B), and thereafter to close the blades upon and part such filling-end.

It will be" understood that when the lay is fully forward, the engagement thereof with the heel 38 prevents the operation of the parting means until the backward swing or movement of the lay following replenishment, but when the transferring mechanism and'lay are in the position shown in Fig. 6, the detent 47 is withdrawn and the blades 33 and 34 would operate to part the filling adjacent the cloth.

.By the two separate parting means above described, the old filling-end is parted in twoplaces, at the edge of the cloth and at the shuttle respectively, and after replenishment the shuttle is shot across the lay, and the fresh filling is laid while the new filling-end, leading from-the hopper or filling'feed-er to the nearer edge of the cloth is left, and I have provided means which i I will now explain whereby on the next forward beat of the lay, a second'operationof theparting means adjacent the edge of the cloth.will be effected to part' the'new filling-end. If nothing were provided to prevent it, the next forward beat of the lay after replenishment would cause the blade-carrier to be moved.

forward'and the spring 54 would return the bell-crank and the adjustable link 48, 49 to normal position, to

' thereby return thedetent 47 to operative positiomand there could not'be two successive operations of the partirig means. Herein, however, I retard the restoration of the parting means to normal or inoperative position,

. and during the retarded period, the lay acts to cause a second parting operation, to part the fresh filling-end; "An upturned and rearwardly extended linger '55 is foimed on the slotted plate 56 which rests uponthe' member 49 of the link and 'isclamp'ed thereto by the bolts 50, the said finger being'normally' on the left of a retarding member 57', Figs. 1 and; 12, and in the present embodiment of my invention," I have shown such retarding member as a prolongation of the upper end:

' of the vibrating actuator or weft hammer W of the filling-detector or fork w at the right hand side of the loo'm. v

The vibrator W is at its extreme rear position, and is just about to move forward when theshuttle is picked -across to the replenishing-side of the loom, so that if the When the vibrator is in its rear-most position, there- 'tarding levice57 is beyond therear end of the finger 55, so that the actuation of the replenishing meehan'ism of the throw of the detent,

is free to withdraw thc deteni. 47, and thereupon the finger 55 is moved to the 'right'ef' thpaeieof movement of the retarding device 57 viewing l, and such retarding device willbe moved forward into position to engage the finger, but on the opposite side thereof, before the'return-of the replenishing mechanism to normal position has released the bell-crank 51, 52. Con= sequently as the vibrator or weft-hammer W moves forward, it will then wipe over the; left hand face of the finger 55 and will prevent the return oftlie detent 47 to operative position for the time being. i

The fresh filling having been shot across, the new filling-end is present between the cloth and thefillingfeeder, and as the lay beats up, it engages the heel 38 of the blade-carrier, the parts then being in the position shown in Fig. 15, and the parting mechanism 'is restored to the condition shown in full lines Fig. 14, as the lay completes its forward movement. The fresh filling is thereby beaten in, and as the lay swings backthe spring 44 operates to project the blades 33, 34 in'open position, see dotted lines Fig; 1.4, to receive between them the fresh filling-end, and as the lug 36 hits the rear end of the slot 31, the blades will be closed upon'and will part such'new or freshfilling-end. By this time,

however, the vibrator W has again assumed its rearmost position, releasing the finger 55 and thedtent, which latter by the action of the spring 54 will press against the side of the shoulder or abutment 42;

When on the next forward beat of the lay, the heel'BS is engaged, the blade-carrier and'shoulder or abutment- 42 will "be moved"forwa1-d, the latter beyond the detent,

so that the detent will snap into place in its operative "position, as in Figs. 12 and 13, so that "when thelay swings back the abutment will bring up against the detent and the parting mechanism is' thereby retained in inoperative position with theblad'es retracted or housed,

untilthe-next replenishment of filling-is called for. When such'parting mechanism is 'in normal position,

the two heels 38 and tare so positioned with relation'to each other as to bepractically engaged simultaneously on the beat-up ofthe lay, so that the temple is moved forward and the parting means bodily therewith, the temple shank-sliding in the stand T in usual'manner, but as the parting means move forward with the temple, the bladesj'will remain 'retractedwithin the housing, and heneecannot interfere with the filling when "the shuttle is boxed at 'the replenis'hing'side of the loom and the loom is running properly.

The adjustable connection between the two parts 48, 49'of the link and the blade .56 prov'idesfor adjustment and for regulation of the retarding finger 55. i f

So far as theretarding device is'concerned, it need not necessarily be a part of the weft'hammen as any vibrating member timed 'to vibrate properly will operate in'the same manner, but in the case of adouble fork loom, the weft hammer of the right hand fork affords at once a-proper and very convenient retarding device to operate as has been described.

, When the detent has been withdrawntopermitthe spring 44 to operate the parting means, the rearward movement of the blade-carrier 32 is limited by the engagement of the shoulder or abutment42 with the pin 46 on the temple stand.

This branch has pivoted to it at 61 a jaw-carrier 62 provided with a downturned heel 63 and with an overhanging broad jaw 64, longitudinally grooved on its lower face at 65, and preferably provided with pads 66, see Fig. 10, of leather or other suitable cushioning material.

in the former the jaws being closed, and in the latter the said jaws are open. The shuttle-feeler arm y moves rearwardly when fillipg-replenishrnent is called for, and

if the shuttle is properly boxed, the jaws 58 and 64 will move across the raceway oi the lay close to the inner end of the shuttle, and fillingsreplenishment will follow,

but if the shuttle is too far out of the box, the ends of the jaws will engage the side wall of the shuttle, and prevent filling-replenishment in a manner common to looms of this type. A lateral pin 67 on the jaw-carrier 62 passes loosely through aslot 68 inthe branch 60, see

Fig. 8, the projecting end of the pin bearingagainsta spring 69, tohold the jaw 64 in open or in closedposition until positively removed therefrom.
