To all whom it may concern:

Be it known that I, JONAS NoR'rHRoP, a citizen of vthe United States, residing at Hopedale, in the county of Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Automatic Looms; and I do hereby declare the following to be a full, clear, and exact descrption'ot the invent-ion, such as W1ll enable others skilled in the art to which 1t appertains to make and use the same.

The present invention relates to an 1mprovement in automatic'looms. The object of the invention is to reorganizeand yimprove the construction of the automatlc loom in certain details hereinafter referred to, for the purpose of improving its operation, simplifying its construction and Afor producing a construction particularly adapted to attachment to existing plain looms,

vwhereby such looms .maybe-"iliade automatic. I l' To the above end Athe invention consists .in theimprovements hereinafter described andv 'iartieul'arly defined in the claims.

js's tion for transfer to the shuttle; and Fig.

The illustrated embodiment ofthe invenl tion is describedas follows: The` hopper, indicated in a. general way by the reference character H, is mounted onl the right hand end of the breast beam B. The breast beam B is supported bythe end frames F, theupper portions only of which are shown. The knock-off lever is indicated at K. The picker sticks are indicated at l. The temples are shown atl T, and the filling detector device D mounted upon'the the breast beam on the left hand side of `the cloth is connected by the usual rock shaft with the hopper mechanism on the right handside of the loom. This rock shaft l is supported in brackets on the frame of the loom and 'provided with a s rin 2 normally tending to turn it in the direction to cause the detector arm 3 and hopper arm .tato move toward the breast beam (sec Fig. 10). The filling detector. D may be any usual or suitable form ofdetectorpfor in'-` dicating filling absence. The hopper mechanism is mounted on the hopperplate 5, being provided with a bracket4 slot,6 which receives the bracket plate 7 of the bracket 11 bolted on the breast beam B- of the. loom. The bracket plate 7 is slotted, and bolts 12 are employed to secure the hopper plate to the bracket plate 7. The adjusting bolt 18 is screwed through plate 5 and engages the top of the bracket plate 7. It is secured in place by a lock mit and affords means, when the bolts 12 are loosened, to adjust the hopper-plate 5 to correct vertical position. Horizontal, lungi# tudinal and transverse adjustment of the hopper mechanism are secured by providing the toot of the bracket 11 Withy longitudinal slots and the breast beam with transverse slots through which the bolts pass, securing the bracket to the l breast beam;

It will be recognized as of importance t0 adjust the hopperto the loom, as .its proper positioning with religion' to the lay is equired in order to secure its coperation with the shuttle. The means which are pro'- vided for this matter' of United States Letters Patent No.

projection on the extension plate 46 has' an inclined end which engages the surface of the boss on they end of the lifter operating arm 43 and preserves a normal relation between thel two, which may be changed owing to the elasticity ot' the spring i4 when the occasionrequires.'

rThe lifter operating arm lifts ythe latch i Y on the indication ot filling absence and throws the shuttle feeler forward into feelingposition, then when the lay beats up, if the shuttle occupies lits correct position in the right-hand shuttle box, 'the :t'eeler does not engage the shuttle and the latch is 'struck by the bunter on the lay, thereby' causin'g an insertion oi a new vfilling supply in the shuttle. r But it' the shuttle is not correctly boxed, it engages the' feelcr, and, throughthe connections between it andthe latch, it depresses the latch, so that it is not' struck by the bunter on the lay. This feeler mechanism is described 'asicollowsr-` The feeler mounted on `the lower end of the fecler arm 51 pivoted at 52 on the hopper plate 5, is provided with an4 upwardly eX- tending arm 53 having a hole 54 in it which receives a pin projecting laterally from the adjusting nut 55 which receives the link 56 by which the feeler arm is connected' with the arm 43 stud 33. l i

The/above described arrangement is such absence is indicated by thel that when filling filling detector D, -the detector arm 3 is mounted on the transferrer operated by the detector D to oscillate the l rock shaft 1 so as to swing the hopper arm to the right, as viewed in Fig. 10, thereby exerting a pull upon the spring 44 and causing it to oscillate the shuttle feeler to-swing it into feeling position. It' when the lay beats up the shuttle isf properly boxed, the feeler is not engaged by" thc shuttle and lthe latch 36 is engaged by the lay and the transferrer is thereby operated to insert a new filling supply inthe shuttle. if, however, the shuttle engages the shuttleV feelcr, the direction to cause a pull tobe exerted upon the link .i6 thereby turning Vthefarrn 43 and 'the arm 4l so vas 'to drop lthe latch 36 out of the pathy ofyvmove'ment of the bunter, so as thereby to prevent the Theaoppergisadvaina ai rangement.

The -feed pawl (50 is also provided withl a right-angled hand 'hold f 65 which is adapted to be [engaged by the hand of the operative for withdrawing the tooth 5l from engagement with the ratchet 62 (the lugv d'limiting this withdrawing movement) when, is,tiesiietl. to turn the hopper backwardforany reason. The shape. ofthe feed pawl 60 1s illustratedin Fig. 5,

which represents the parts in the saine po- Sitlon as that -in which they are shown 1n Fig. A3lout with -the transferrer and trans-A 'ferrer itttch removed. The feed pawl isprovided with an opening' (S6 which receives the 'l end of the arno 67 of the feed pawl operating lever 70 pivoted at 71 upon the hopper plate 5. .The feed pawl operatinglever 7 0 is a' bell crank lever of which the arm 67 is vsubstantially horizontal and the other arm @substantially vertical. The Vertical arm 72 carries at its lower end a feed latch 73 which constitutes one arm of the feed latch lever 745 pivoted at 75 upon the verticaharinlever 70 occupies its advanced position, as

indicated in Fig. 7. The feed pawl 60 is provided on its under side with a projection v lnencircled by a spring 80' which engages the upper face oftheabutment stand 78 and" normally ends to move the feed pawl (3() in the direction to'cause it to advance ,the

. hopper, that is, to feed the hopper forward to bring a'new bohbin into position vto be inserted in the shuttle. Byreference to Figs.

5 and 7 it will be observed that the feed pawl operating lever and the feed pawl 60 are so articulated together that the movenient of the one will cause the movement of latch 73, it causes the feed pawl operating lever 70 to be turned to the Aposition yindicated in Fig. 5, thereby lowering the feed pawl, compressing the springrSO, and bringing' the feed pawl to the set position indicated in Fig. 5. Upon the retraction of the bunter 37 from engagement with the feed latch, 73, the latter falls to the position subsequent forward beats of t eEstAvAiLAeiEooP* shown in dotted lines in e lay, the feed latch 73 is untouched, the feedpawLrenain- 7, and upon i ing in its set position ready telf/eed the bopper when it is permitted .to doso by other conditions of the inaphine. W'hen the feed pawl GO is/in set position. the feed .latch 78 normally occupies its lowered or inoperative position, but when filling absence is indicated by the filling detector and the transferrer latchl 3G is raised, a pin 8G inside of4 the latch engages the feed latch 73 land .liftsl it into operative position, so that whenever the transferrer is operated owing to the lift'- ing of the bunter transferrer latch, both latches are presented to the bunter. As a result of this, when the bunter is forward, it engages both the transferrer latch and the feed latch, and while it is inforward position it holds the feed pawl operating lever y 70 in the position shown in Fig. 5 so that the feed of the-hopper does not take Place nlntil after the lay has retreated a'nd the transferrer has risen, so there is no impinge- 1ment of a bobbin against the face of the transfcrrcr. The arm 67 of -the feed pawlv operatinglever is provided with a downwardly extended' proection '81 4carrying upon its end a laterally extended stop dog which is adapted to engage the butt recesses H3 of the butt-,end disk G3, as indicatedv in Fig. 7, which shows' the position 0f the parts after the feed of the hopper following a holibin transfer. Thus it is seen that the enl@agement of thil endmost bobbin with the abutment S4 is not relied upon to stop the advance nioven'icnt of the hopper, lout the advance inovcnient of the hopper is positively determined hy llie engagement of the .stop dOAL'SJ with the advancingwall of the recess 83. The absence of rhololiins does not interfere with the operation of the hopper. It is still fed, step by step, one bobbin space at a time, in order to advance the hopper to a position where a full liobhin, if there be any in the hopper, will be presented to the transfert-er. The use of the stop dog S2 in the construction described secures this new molle of operation. Fig; 9 illustrates this operation. The bottoni of the hopper is empty and consequently the feed pawl is sot at cach beat of thel lay, and upon thew back stroke of the lay `the `feed pawl advancesl the hopper -onc notclnthe stop dog preventing it from adv'an'cilntg` more than one notch. At eaeh'timethe feed pawl rises it swings the feed latch forward and thereby lifts it into position to be engaged by. the

until the feed of the hopper by the feed pawl is prevented by the engagement of a bobbin with the abutment 84. 'With the parts in the position illustrated in Fig. 9, the feed .pawl 60 has just been raised by its spring, thereby completing a feeding stroke 'bunter on the lay. This operation'continues BEST AVAILABLE CQP and at the same timei swinging the feed latch 73 forward and raising it intofposition to be struck by the dagger on the lay. .It is apparent that with two bobbinspaces empty at the bottom of the hopper, as showmthe hopper will be racked forward two spaces before the bobbin 85 strikes the vided with a hand hold Sli? which projects outward a\va \Y from the butt-end disk G3 and is adapted to be engaged bv the hand of the operative in order to lift the pawl off the rack 62.' The feed pawl tl() and the stop pawl arc independent of each other. The feed paw-l may be lifted eti' of the rack 62 without disturbing or touching thestop pawl 90. No also the stop pawl El() mayy be with-A drawn from engagement with thc rack 62 without movement ot' tir-interference with the feed pawl (SO. Like the feed'pawl G0 a stop pawl 90 provided with the projection 93 which projects toward the butt-end plate G3 and enters the space'inside tlie ratchet. (i9. Se the stops (-t and H3 respectively prevent-,i the feed pawl and stop pawl from being moved so i'ai' as to canse either to engage and lift the other pawl.' The two projections or hand holds G5 and 92 are located near each other so that it is convenient for the operative to engage both with the hand so' that both may be lil'ted from the ratchet- (at the same time without' there being any mechanical connection between'the two pawls. t v- .'lhetsmall-end disk 100 supports the bobbin tips. The disk is provided with a hub 101 mounted on the stud 102 which supports the hopper. said Stud being mounted in the hopper plate 5 Vand secured therein by the set screw 103. The disk is provided withA slots'lOt which afford provision for supporting the tip springs 105 in place. These springs are 'loose steel springs of the shape shown in Fig. 2, cach having a grooved tip holding projection 10G near its end. At the inner end of cach spring is a hole which recelves the pin 107 `projecting.outwardly from the disk. The springs are sprung m A vplace and held by their elasticity in position.

The bobbing` are inserted in the hopperv by putting their butts in the recesses 83 within .the lip 110 of the hopper plate 5 and by placing the tip against-the projection 106 on the end of the spring and forcing the bobbin tip overthe projection against the portion 11i-of they disk. .The lip 110 extends fromthel'owettpart' of the front' of the pla-te 5 around the periphery of the plate weil lt0- ward the abutment where it terminates, as seen in -Figs. 3, et, 5,'7 and 9. u This brings us to the yielding bobbin snpport. which will now be described. The lip ll() cooperates with the recesses 83 to hold the butts of the bobbins in place in the buttend disk. At the bottom of the hopper where the bobbin is discharged from the hopper by being moved radially out of it. by' the transferrer, the lip 110 is omitted. but here the bobbins are prevented from falling or being-jarred out of the recesses 83 by the `vielding bobbin' support 112 which consists of astrip of metal having a rounded or bent end. as seen in I*`igs. 3, 5. T and 9, adapted to engage the butt of a bobbin at the time it is being transferred from the hopper to the shuttle. The body of the' bobbin support is, flat and extends rearwardly, being supported in 'the space 113 in the block 11st on the lower side of the hopper plate 5. The rear end vof the bobbin support is up'- turned at and a spring 116 engages such rear` end and normally presses it for.-

` ward into the position shown in the drawiiigs. while permitting it to be moved rearwardly* to.eompress the springwhen a bobbin isremoved from the hopper. A cover plate holds the device in its cavity in the block lll. 'lhis'bobbin support is, in a sense, a continuation of the lip 110 of the. hopper plate 5,'and has capacity to vield in a direction away from the abutmenti so as to permit the escape of the bobbin from the hopper.

'lhc abutment and the bobbin support. together with the transfcrrer 30 and tip depressing arm 1.177 comprise the, means for moving' and guiding the bobbin from the hopper into'the sliuttleyand an additional means for securing the correct placing ot' the bobbin in the shuttle is found in the tip holder, as it is called. In inserting a bobbin in the shuttle the resistance oi'ered to the insertion of the bobbin by the spring clamp which engages the butt of the bobbin is sometimes such as to cause an accidental displacement' of the bobbin in the slijnttle from its correct, position. Sometimes the tipl of the bobbin is so far depressed as to' l'project bclowthe surface of the. lay. 'It is desirable, therefore, to provide means for supporting the tip of the incoming bobbin duringthe time it is being inserted in the shuttle. The means which has been provided for accomplishing this; purpose is described as follows :-Upon the end of the stud 33, which supports the transferrer, is mounted the tip holder arm which is a vrigid arm secured by the set screw 121 to the stud 33. This arm projects in a general downward and rearward direction from the stud 33 and ieprovided at its end with a icaA ses? AVAILABLE coi interes which is slidingly mounted in the hole 122. The tip holder 123 is provided in' itsl front end with a hole which receives the lower end of a spring 124 which is secured to the arm 120 and resiliently presses the tip holder 123 into the position illustrated in Fig. 9 vof the drawings. When a vfull bobbin, is to be- -transferred from the hopper to the shuttle,

it is forced downward by the transferrer anditself displaces the spent bobbin to be removed from the shuttle, forcing it downward. vAtthistime, of course, the lay is for- `ward and the tip holder 123 projects `under the shuttle, so when the spent bobbin iirst emerges from the shuttle its tip hits the tip holder 123 and is prevented thereby from immediately falling or from vbeing driven with high velocity away from the shuttle and the tip end of the spent bobbin is iii position to be engaged by the tip of the bobbin being'inserted. It thereby prevents the tip of the new bobbinbeing inserted from kbein depressed .beyond a point from which vit will spring back into proper position in `as described so as "to yield iii-case anything A y as, for`example, t e
