minaretmea -ember, 5, 192 s. Serial No. 312,700;

The present invention relates to looms'gfoi" weaving cloth, and has particular reference to animproved holder for the threads which areleft on the-selvage edges 'oi thecloth, so

that the temple may cut such threads; I Heretofore'," no satisfactory means or method; has been foundto out thefltli'r e'ads on the left hand o or box side of the loom, although successful devices have" been utilizedi' forcutting the threads on" the right hand 'sid'e' of the cloth. I I

It is thereforethe prime purpose of the present invention to provide an improved holder and: operating m eans therefor to: a c 1'5' complish theobject off-cutting the threads on tlie'lftihand' or box sideof th'e loom.

Another object; of the invention is to ro vide an improved; holder for use connection with a-left hand temple cutter which operates in the regular manner, so that the device is inthe form of anattachment'whiohniay be applied to looms already constructed and which are being manufactured according to the present construction, I v I The improved holder-holds the thread after the-temple has" cut'the' thread apart from side of the cloth hyth'eregulai" method,and continues to perform its function for all' changes thattalie place in filling threadsiand 3o: enables the temple to cutv thread'clo'se tosel vage of the cloth;jthus'sa ving the time here tofor'e used in cuttingotf'threads bj1,l1and aswe llas the loss off ma'teria'l where the singee ing=methodis used" instead. of cutting, off by, ss han'd. Theimproved holder works in connec'tifon with the. box change and performs its duty just as accurately, and is actuated bythesa'me chain that works boxes to put in thevarious fillings;

Theinvention further aims at the provision' ofa temple'cutter', holder and'operating mechanism therefor which is adapted to save the laborf'ormerly used in cutting or singein'g ofi thread s' on the box side 'ofthe selvage, 45 'as well as the saving of material hitherto lost by siiigeiii'gg'also saving the'y'arn which is 'used up in the 7 usual method" by the yarn. followingalong the selvageuntil itis again" used for fillingi I I I The i-nveii tion also aims to provide device" offthi's character which eliminatesall waste onthe'selvage of the loom and which heretofore wasa total lossa'sthis waste'has to be either singed" o1" cutoff with scissors hand, an operation which is very 'ex'pensive' as well as ivery trying'fon'the hands who had to'use scissors in Clipping this vthread' from the selvage of the cloth.

Other objects and advantages will be ap' parent' from. the following. description when considered in connection with the accompanying drawings and will be more par-c ticularly pointed'out in the appended claims,

Referring now tothe drawings, 15 desig? nates' the selvageedge 01" cloth bing w0v*eh,', the same/being shown in' dotted lines, 16, shows aconventional temple 'cutter'in dotted lines and which is providedwithcutting jaws 17. The holder of'this invention is located opposite to the temple cutter 16, andis constructed-as follo'ws': The holder has an arm 18,'loest shown'inFigures 6 to 9, andwhiblt.

projects rearwardly in a vertically edgevvis e' f pos'ltlon, and which ,at 1ts rearnd pro ects downwardly at an angle and is provided near its lower edge portion with a laterally extending fixed jaw 19.

As shown in Figure 1, the thread which extends from the selvage edge 15 of the cloth being woven, passes over the face of the aw 19 and through a guide notch 21 in the rear edge of the arm 18 and which is disposed opposite to the jaw 19. The arm 18 carr es a side plate 22 which is located at the side of the arm 18 from which the fixed jaw 19 projects. This side plate 22 is provided at its inner side and near its rear end with a bushing which constitutes a spacer as shown at 23 for holding the plate 22 in desired spaced relation from the side of the arm 18. A machine screw 24 or the like engages through the arm 18 and into the spacer 23 for securing the parts together in the form of a frame. A yielding or movable jaw 25 is disposed between the arm 18 and the side plate 22, and is pivotally mounted at its forward end upon a pin 26 which is secured to the arm 18 and the side plate 22. The jaw 25 is normally urged downwardly by a spring 27 which is interposed between thespacer 23 and the jaw as shown in Figure 6.

Between the arm 18 and the side plate 22, and forwardly of the pin 26, is a retaining lever 28, which is pivoted at its upper end upon a pin 29 and which has its upper end adjacent to the pin 29 curved rearwardly and upwardly so as to offset the upper end of the lever 28. The retaining lever 28 is also provided, at its bend or angle portion, with a lug 30 which projects forwardly from the lever 28 substantially opposite to the upper end thereof.

The rear forward end of the lug 30 is pivotally connected to a headed or shouldered rod 31 which is mounted at its. forward end in an upturned guide flange 32 of a bracket 33. The rod 31 is provided with a coil spring having one end bearing against the head of the rod and with its other end engaging the guide flange 32 of the bracket so as to normally urge the rod 3lrrearwardly and thus yieldingly hold the lug 30 in its raised and lowered positions.

To the lower end of the retaining lever 28 is pivotally mounted the forward end of a thread catching loop or hook 35, the same being pivotally mounted on a pin 36 carried upon the retaining lever 28. The hook is in the form of a double hook and may be constructed of a single piece of sheet metal which is folded over upon itself at its forward end and which has parallel arms which project rearwardly for engagement at the opposite sides of the movable jaw 25. The forward closed end of the hook is curved downwardly beyond the retaining lever 28 a.

disposed substantially opposite to the pin the rear end of the holder.

36, while the forward shoulder 38 is curved on a relatively long radius and extends downwardly beyond the retaining lever 28 and terminates at the lower end of the hook 35. The bills 39 of the hook 35 open downwardly and are adapted to slide in grooves or ways 40 which are formed in the upper face of the fixed aw 19 at opposite sides of the movable jaw 25.

From Figure 8 it will be noted that the movable jaw 25 is of less width thanthe space between the arm 18 and the side plate 22 so as to provide guideways or recesses at opposite sides of the movable jaw 25 for the reception of the spaced arms of the hook 35.

The bracket 33 is provided at itsrear end with an upstanding slotted guide flange 41 through which the forward end of the arm 18 slideably passes. so that the arm 18 may move forwardly under pressure. The outer extremity of the arm 18 is headed to limit the rearward projection of the arm through the guide flange 41 and is also provided with a guide rod 42 which slideablyv engages through the forward guide flange 32 of the bracket. A spring 43 is mounted on the rod 42 and bears at one end against the guide flange 32 and at its other end against the head on the forward end of the arm 18 so as to normally project the arm 18 rearwardly from the bracket. The bracket 33 is provided, at a point between the guide flanges 32 and 41 with a longitudinal slot 44 through which engage headed set screws 45 secured in a bracket plate 46. The bracket plate 46 extends-transversely beneath the bracket 33 and is provided with a rearwardly and downwardly inclined bearing face upon which the bracket 33 rests. The bracket plate 46, Figure 1, is provided with an at taching lug 47 for receiving a screw 48 for adjustably mounting the bracket plate on the base plate 49 carried on the breast beam 50 of the loom.

The holder thus described is so mounted upon the loom, as shown in Figure 1, that the lay beam 51 operates toward and from receive the thread 20 at the side of the holder opposite to the temple cutter 16. It will be noted that the thread guide 52 has its arms flaring or diverging rearwardly with one arm disposed above the other so as to catch and hold the thread and permit of the move ment of the lay beam 51 without losing the thread 20. The lay beam 51 is disposed substantially in line with the rear shoulder 37 of the hookand as the lay beam 51 approaches the end of its forward stroke it strikes the shoulder 37 and actuates the hook 35.

For the purpose of tripping the hook 35 rearwardly, by operation of the'box change A suitably ammo:

mechanism, a bearing bracket 53 is mounted on one side of the loom frame 54' and a rocker shaft55 is mounted in the bracket 53 with one end extending beneath the holder. The inner end of the rocker shaft 55 is provided with a trip arm 56 which extends upwardly and has a curved upper end adapted to engage the forward shoulder 38 of the hook 35. The outer end of the rocker shaft 55 is provided with an upstanding arm 57 pivotally connected at its upper end to a connecting rod 58 suitably bent or shaped to avoid contact with the adjacent parts of the loom and which at its other end is pivotally connected to an arm 59 of a bell crank lever, the arm 59 extending upwardly and normally inclined forwardly to a slight degree. The other arm of the bellcrank lever extends downwardly and forwardly, in normal position, and is pivotally connected at its lower end to a vertical rod 60. A bracket 61 is secured to the loom frame 54 and pivotally supports the bellcrank lever 59.

The vertical rod is provided at its up- I per end with an adjustable coupling head 62 which has pivotal and rocking engagement with the outer end of a cam lever 63 pivotally mounted at its outer end upon bracket arms 64 or the like. The intermediate portion of the lever 63 is provided with a clownwardly extending cam 65 the shoulder of which faces toward the inner or pivoted end of the lever 63 and lies in the path of a travelling cam 66 mounted on the chain 67 which operates the box change -mechanism. The travelling cam 66 may be in the form of a link inserted in the chain 67 so as to be operated thereby in predetermined timed re lation for engaging the cam 65 under lever 63.

From the above description it is thought that the operation of the machine as applied to a loom will be clearly understood, Briefly stated, when the chain 67 travels sufficiently to bring the cam 66 beneath the cam 65 of the lever 63, the interengagement of the cam lifts the free end of the lever 63 and draws the vertical rod 60 upwardly with the result that the bellerank lever 59 is rocked and the connecting rod 58 is shifted to actuate the rocker shaft 55. This movement of the rocker shaft 55 brings the free end of the trip arm 56 against the forward shoulder 38 of the hook 35. The hook 35 is uplifted or swung upwardly on its pin 36 to free the thread 20 andthe hook 35 is also projected rearwardly from the holder arm 18, swinging the lever 28 rearwardly at its lower end and bringing the lug 3O beneath the longitudinal axial line of the pivot 29 so that the spring 34 comes'into play for yieldingly holding the hook 35 in a rearwardly projected position.

During this forward projection of the hook 35, the lay beam 51 is moved away from the holder so that the threakib.guidev 52" ca-rries;

the; thread 20 therewi-tln As;so0n',,l10Weve1, asathellay. beam. 5lbeats'up toward the hold-,-

en,;the; thread 20.:is carried into the regionv .ofthe holder and thebeam- 511toward; the end: of its inward strokestrikes against the front 35' doi'vnwardly: into the lower fixed l9 and causes the hook to engagethe thread 20- and pull it in-toposition between the fixed: jaw 19" and the upper movable jaw 25. At,

thisitim'e, the ling: 30 'is swung upwardly be; yondthehorizontal axis, of the pi'n 29 and= the spring-34- yieldingly holds the lever 28: in this new backward. position. noted that when the temple 16 cuts the thread, the improved holder will hold that thread for the yarious operations. of the box and other cooperatingfpartsof the loom.
