My invention relates to controlling and indicating mechanism for looms. .Y

Diiculty has heretofore been experienced in weaving lengths of cloth of detinite yardage. In an effort to obtain such lengths, the practice of measuring the warp yarn and marking it in the slasher with colored or socalled cut marks has been followed, but this method is unsatisfactory since with diierent filling and different numbers of picks per inch different lengths of cloth are produced from a given length of warp. Further, the weaver is required to watch each loom closely in order to shut it down when the cut mark comes up in the process of Weaving. Thus, in y many cases, and particularly where the weaver has a large' number of looms to serve,.

`the cut mark is passed. As ra result, the Weaver has to shut down the loom and roll back the cloth to find the, mark. This results in serious loss, arising lnot only from the short pieces thus produced and the delay, but fromthe doubling and Wrinkling of the cloth during the rolling back process, which frequently requires the rolled back cloth to be classed asseconds. Another method of determining the length of the cloth woven has been to have the operative responsible for removing the cloth measure the diameter of the roll, as by a stick or the like. This method is also inaccurate, as no two looms are alike in 'the density with which they roll the cloth, so that, as a result, on different'looms the same"` diameter of roll will represent quiter'adically different yardage. This method isalso fur:

ther inaccurate since an error in measurement of only a sixteenth or an eighth of an inch,

when the roll of cloth is twenty to forty inches in circumference, causes a variation of several yards of cloth. Further, the operative whose duty itis to remove the cloth and who ordinarily has several hundred looms,` under his care, has to cover all of the various looms and does not know without an actual inspection of each looml and measurement with his stick which loom is ready to have vthe cloth removed. Y

. My invention has among its objects to pro- 'I yvide van improvedcontrolling and indicating mechanism for looms, which is adapted to req PATENT orisiclaiv FREDERICK GORDON COBB, CELANCASTER; SOUTH CAROLINA, AssIGNoR To vi'ianrin- 4' move the. above difficulties and substantially y to reduce production ,costs and which is,vfur ther, particularly adapted to use under modern conditions where many looms are caredf for by each weaver and each operative whose duty it is to remove the cloth. A more specific object of my'invention is to provide anfimf,

linvention are to provide anlimproved `and simplified structure wherebythe above obn ljects are obtained'andwhich, further, is capable ot' being produced economically and l readily applied to a wide variety of looms in general use without change in the loommech'- V 00 f anism. These and still other objects and advantages of my improved construction will,y

however, hereinafter more fully appear. `In the accompanying drawings I have shown, for purposes of illustration, two. em-

bodiments which the same may assume in practice.. v. Y L i ofa loom equipped with my improvement Fig. 2 is a'plan view of my improved con- Figure 1 is a perspectiveview of a portion i broken away to facilitate illustration;

Fig.- 6 is a detailend elevational View of the drive mechanism connected to the counter, the view being from the left at the top of Fig. 5, and y Fig. 7 is a perspective View of my improved controlling mechanism applied to a different type of loom, certain of the looml mechanism being removed to facilitate illustration.

In the .illustrative construction shownin Figsrl to 6, it will be noted that I' have shown a loomvof a standardtype including the usual frame 1, take-up roll 2, Aand Draper type stop motion 3, 4with my improved" mechanism carried vvon the framel yand operatively connceted between the take-up roll 2 and stop motion 3, yas hereinafter more specifically, described. f j

' Considering f'my 4 improved mechanism` more particularly, it will be noted that it in# chicles a Vcounter or register 4,comprising transfer' mechan sm having usual operatively connected transfer members or number wheels, *carried in-,a suitable casing 5 and herein attached tothe upper cross member of the loom `frame`1 in a readily'visible position and driven from the usual gearing which drives the ltake-up roll 2, an'diincludes the changegear which regulatesthe number of picks offilling. Herein, the roll 2 is driven by usual spur gears G and of that gearing, of which the former is coaxial with the roll v2 while the meshing intermediate gear 7,

driven-by the change gear (not shown),v is larger and located below the gear 6, and both are, as usual, journaled on'the *frame 1. As

showrnthe gear 7 herein lalso meshes with a ylaterallydisposed, rmuch smaller pinion 8 suitably supported and journaled inside the frame 1 in a `suitable horizontal supplementary frame 9 fixed tothe frame 1. This pinion 8 preferably also has integral-with it a l 'coaXial beveled pinion.` 10 which in turn meshes with a cooperating'beveled pinion 11' on ahoriZon't-ally extending shaft 12 perpendicular to the axis of the roll 2 and likewise journaled in the frame 9. This shaft, on the opposite end from the pinion 11, also carries ay similarA beveled pinion 13. This herein meshes with a cooperating, similar beveled number of yards.

pinion 14 likewise journaled in the frame 9 ybut vertically disposed. This pinion 14 is connected through shafting including a universal joint 15 with an upwardly disposed drive shaft 16, which is in turn connected through a corresponding universal joint 17 Y with the -lower end ofv a vertically disposed counter'driving shaft 18 suitably journaled in the-.frame 19 of the counter 4. Herein, it

will also be-noted that this shaftV 18 carries on its upper end and 'within the counter casing a worm k20 which 1n turn meshes with a gear 21, carried on-the transverse counter shaft 22 and operating the counter mechanism 4. The latter mechanism being of usual construction, it will thus be evident that, the size ofthe take-up roll 2 vbeing known, andthe counter 4 being driven from the driving connections of that roll through the driving connections described, the counter 4 willindicate at a glance in terms of yards the yardage completed at any given time. Also, the relation between the roll 2 and vits drive being constant, it will be evident "that the'yardage count will be accurate irrespective ofthe sizeof thel pick gear used, and that no corresponding adjustment of the mecha` nism is necessary whenv the pickv gear is changed.

Associated with this yardage'counting mechanism is also improved setting mecha-v as desiredand ,operable after nism adjustable the c'oinpletimil age. Hereinit nism includes of any predetermfned yardwill be noted that this mechadisposed at right angles to the counter shaft 22andjournaled in a vertical portion 27 of the counter support-ing traine 19. This shaft 26l herein extends to the oppositeside ofthe frame 1 from the portion 27 through an elongated bearing `28fin the' frame 1S).

a gear 25, likewise meshingl with the Worm 2() but carried on a shaft 26 loo It also carries on its oppositeend a'wor1n129 which Y in turn meshes with `a cooperating gearO suitablyv fixed tothe upper end ofia vertical shaft 31, vas by a nut 32. turn is Yjournaled in a'suitable bearing 33 at right angles to the bearing 28 .and carried on a supporting member 34' adjustably connected, as by bolts 35, to the verticalportion 27 of thefcounter frame. Herein, these bolts35 no This'shaft V31 inV` i extend through suitable sleeves 36 formed on theA frame portion`27` and extend below the frame 1, while the portion 27 has lugs 37 suitably attached to the counter carrying side of the frame bysuitable means, as for example bolts`38. Thus,"it ,will be noted that depending upon the gear and worm combiy nation 29,80, the shaft Sluill be rotated slowly so as to make ay complete revolution during the completion of any predetermined Further, by releasing the boltsV 35, laterally j 30 of different size to engage with the Worm the member 34 may be adjusted in suchmanneras toenable gears f 29, while obviously further variation may be obtained by changing the worm.

Associated with the mechanism just described and operative in vany. setting ofthe latter, is improved trip actuating mechanism, which is in turn operative through mechanism controlled thereby and hereinafter described, to stop the loom after a predetermined yardage has been com leted. Herein, it will be noted that the shaA t 31 has pivotally mounted thereon near its lower end a horizontally swinging pawl 40. It, further, carries below this pawl a disc 41 suitably adjustably attached to the shaft, as by aisetscrew 42, so j that it rotates with the shaft. This disc in turn carries an upstanding pin 43 which is adapted, upon rotation of the disc, to'engage the pawl 40 and cause it to swing about its axis on the shaft 31. Thus, it will be evident that with the parts suitably adjusted, after a predetermined yardage has been .completed the disc 41, which is slowly rotated throughout the operation of the counter, will be rotated in such manner as to drive the pin 43 and the pawl 40 to complete a revolution upon the completion of the predetermined yardage determined by the gear and worm 'setting then in use. Obviously, the same result will also occur when different gear and worm sizes are used.

Associated with the trip actuating mechanism above described, is also improved stopy 47 also has a coiled spring 51 thereon acting,` between the extension 50 and anv adjustable collar 52 carried on the rod above the member `48, while the rod also carries, nearerits lower end, a similar adjustable collar 53 engageable with the top of the extension 49. Herein, the rod 47 is bifurcated at one end and between its ends provided with a resilient vertical extension 54 which, like the rod 47, also moves in the extension 49, herein in a suitable perforation 55. -,Herein, this portion 54 is also provided near its .upper end with a notch 56 and adapted to interengage,

in the elevated position ofthe rods and when the spring 51 is compressed, with a cooperating ledge 57 on the portion 48, a knifeedge connection preferably being provided for accuracy. It will also be noted that it is provided with a, beveled upper end 58 adapted to pass up along the ledge while springing the portion 54 outward into notch engaging position, and that this end 58 extends into the path of the pawl 40 whenthe notch 56 is hooked over the ledge57. Thus, it will be evident that whenever the pin 43 causes the pawl 40 to complete al revolution, i. e. upon the completion of any.predetermined-yardage 51, until the collar 58 on the member 47 en-` gages the lateral projection 49 on that frame. ssociatedmwith the members 47 and 54 above described, and movable 4therewith and herein carried, through means hereinafter described, at the lower end of a bottom portion 59 thereon, is improved means adapted to c ooperate with the loom stop motion in interrupting the operation of the loom. Herein, these means, assume the form of a member 60 adapted to move vertically with members 47 and 54. lVhen used with a well known Draper stop motion, as illustrated herein, this movement of the wire stop 63 connected therej to, which, it will be understood, in turn controls the eccentric bushing and clutch lever common to' such Draper stop motions but which are not shown herein. Thus, the member 54 acts, when in its own'elevated position, to hold the member 60 in an elevated position above the fan 62. In this position, the stop motion will be free to operate normally whenever a thread breaks and one of they drop wires 61 carried on the thread falls between its comb and the tan. It will be evident, however, thaty whenever thev pawl 40 so engages the upper end`58 of the member 54 as'to cause-the notch 56 to release the portion 48, the members 47, 54 and 59 will move quickly downward in such manner as to klower the member 60 and, through the resultant interruption of loscillation of the fan 62, and the consequent operation of the clutch, shut down the loom justas if a thread had broken.

While non-adjustable means may be used under certain conditions, I have also showny improved adjustable connections between the member 59 and the member 60 whereby, while retaining a simple and rugged character, the mechanism may be made adaptable to various conditions in various looms. More particularly, it will be noted that a suitable adjustable collar 64 is attached, as by a setscrew, to the lower end ot the rod 59, and that this' collar has pivoted thereto, as at 65 and on an axis at right angles to the-rod, a. similar setscrew held collar 66, which in turn carries a rod 67. This rod 67 in turn carries a collar 68, similar' to the members 64 and 66, and is connected by a pivotk 69 at right angles to the rod with another collar 70 which is attached to the upper end 71 of the vmember 60. Thus, it will be observed that a wide range of adjust-ment is made possible between the portion 59 and the member 60 in such manneras to enable the latter member to be disposed at various elevations and various angles adapting it to a wide range ofadjuetment in service. 1 ,"l

Associated with themechanisn so far described is lalso improved indie-ating mechanism movable into indicating position whenever the part 60 'is dropped and movable into inoperative position vafter the cloth has been removed and the mechanism re-set. This mechanism herein is carried on the frame 45 and moves into indicating position upon downward movement of the member 47. More particularly, it will be noted that an indicator in the form of a so-called flag or disc 75, ordinarily painted brightly to attract attention 'extends upward from a pivot 76 on an upward extension 77 on the upper end of the frame 45. Herein, a short curved lower end 78 is provided on this member 75 on the other side of the pivot from the flag. This portion 78 in turn extends into the path of a lateral lug 79 preferably carried on a collar 80 adjustably fixed on the upper protruding end of the rod 47. Attention is also directed to the fact that the flag portion 78, when depressed by the lug 79, causes the flag 75 to swing over center, as shown` in Fig. 4.

,Also, when the lug is raised, the fiag is free to be swung back manually into its inoperative horizontal position. Thus, when the Hag 75 is up, it will remain up even if the rod 47 is raised. On the other hand, when the flag is down and the rod 47 is dropped down by the raction of the pawl 40, the lug 79 will engage the portion 7 8 of the flag and elevate the latter into the indicating position illustrated in Fig. 4. Accordingly, whenever a predetermined yardage hasbeen completed', not only will the loom be stopped, but the indicator or flag 75 will be raised. Thus, the operative having charge of cloth removal on the looms in a room will be able to tell at a glance over the room which looms are ready to have the cloth removed, while production is greatly increased by causing the looms which have made a predetermined length of cloth to have attention at once and thus prompt-ly be 4put back into operation. Attention is also directed to the fact that my register is so located in the drive of the tripping mechanism that it totals the output of ,the loom, i. e. the yardage of the successive predetermined lengths, and does not require resetting. More particularly, it will be noted that no resetting whatever of the register is required, the vsame instead continuing to y.count the yardage in the predetermined the operation of the several mechanisms will be clear from the foregoingdescription, and

that a detailed description of the operation is accordingly unnecessary. Instead, it is be` lieved to be suflicient to say that, depending upon the gear and worm combination 30, 29

in use to predetermine the numbcrof yards desired, the loom will be stopped by the member 6() engaging its fan 62 whenever the predetermined yardage has been completed and the Hag or indicator 75 simultaneously raised to call the attention of the operative' to .the need for removing the cloth. Further, it will be evident that when the cloth has been removed, it will only be necessary to raise the member 59 and its associated rods 47 and 54, so that the notch 56 on the latter engages the ledge 57 on the member 48, and press down the flag 75 by hand,A in order to re-set the whole mechanism. It will of course also be evident that at any stage the yardage which has already been completed will be indicated on the yardage counter 4, thereby giving the operators an yadditional indication of the rogress of the loom toward ycompletion of its'predetermined yardage.

In Fig. 7 I have illustrated my improvement applied to a stop motion of the Grompv conditions, each of these men has to lookl after man looms, running, lfor example, in the case o the weaver, from 50 to 100, and in the case of the operative who removes the cloth, from four to eight hundred in number.,v

The weaver by a glance at the counter can keep track of the yardage completed. Further, whenever a loomis stopped, if the flag ispup, he knows, even fromadistanoe, that it has woven its yardage, and accordingly does not need to go to 1t; whereas, .when a loom is shut down and the `Hag is not raised, he knows that a broken thread or other diiculty makes it necessary to go to that loom.

Also, it will be noted that in this construction the mechanism operates without change irrespective of the size of pick gear, thereby 'eliminating all delay incident to adjustment ofthe yardage counter after a change in pick 'i gears. The weaver also is wholly freed from the necessity for watching for the cut marks on the warp yarn heretofore used to indicate 'based upon length, and consequently, can leave the looms to their own devices in that regard. As a result of these and other advantages obvious to those skilled in the art, it will be evident that each weaver can attendto a substantially greater number of looms. As for the operative Whose duty it is to remove the cloth, he can ata glance over the room ascertain which looms have their flags raised, and thus concern himself only with those looms and go directly from one to another. Further,as compared with the previous stick method of determining yardage, the human element is eliminated and accuracy ot yardage assured. Attention is also directed to the act that due to my improved construction, evenl should a weaver raise the rods and re-set the mechanisni. the flag will stay up and thereby call the cloth Vremovers attention to the loom. From the mill standpoint, also.fnot` only is the mill enabled to lill quickly and efficiently orders for rolls ot a given yardage, but the time loss required in rolling back rolls is eliminated. and the creasing ott-he cloth incident thereto is also avoided, asis also the time required to cut oft the excess yardage and the large losses incident to the sale of the short excess portions as shorts, remnants, etc., which must be sold at a discount. An Overseer coming into a room is also enabled at a glance to determine by the number of raised flags Whether the cloth remover is keeping up with his work. Attention is further directed `to the fact that the average worker prefers the mechanism since no figurin, T is necessary. and he can keep better ltrack of production in terms of yards than be can in terms ot picks, as Aindicated in certain previous devices. lso, since pay isv production, disputes which are frequent where pick measurements are used, are minimized by my improved mechanism. Other advantages Will also be apparent to those skilled in the art.

Thilo I have herein specifically described two embodiments which my invention may assume in practice, and have particularly described the same as driven from the takeup roll drive and acting uponthe stop motion ot the loom ordinarily operative to stop the loom when a thread is broken, it Will be un-v derstood that these embodiments are described for illustrative purposes and that in certain embodiments the invention may be modified and cooperate With other elements and also include speciiically different mechanism, all Without departingr fromits spirit, and that I intend to include all such modifications wit-hin the scope of the appended claims. f y
