Application'June 12, 1941,'Seria1 No. 397,807 10 Claims. ((31. 28-28) This invention relates to an attachment for textile machines and more particularly to a device for marking the warp, while passing through the slasher with apiece of tape so that the'tape will engage a part of the attachment, applied to a loom, forstopping the 100m when the portion of the warp carrying the tape reaches a certain point in the loom, thus'eliminating the necessity of having thewarp constantly watched while passing through the loom, so that the loom will be stopped when a cut mark on' the warp reaches a certain point in the loom,

It is important that the cut marks show on each end of a roll o'f'cloth to insure that the cuts aretaken off at uniform and specified lengths,

Other objects and advantages of the invention will hereinafter become more fully apparent from the following'description of the drawings,-which illustrate a preferred embodiment of the inven- 5: tion, and wherein:

not only to satisfy the buyer of'the cloth, 'but also to afford a check on every'yard of cloth woven, to insure that no cloth hasbeen' destroyed or stolen from either end of the roll. Where cut marks are not provided, employees frequently tear'off cloth from the ends ofia roll for use for towels, aprons and other purp'oses'and this cannot be checked to prevent it without the use of a cut marking system, and unless checked creates a very large loss.

forthe cut marks, due to the large number of looms which each weaver looks after and consequently many mills have abandoned the" cut marking system for this reason.

It is therefore a primary aim ofthis invention to provide an improvement in the cut mark ing system which will operate automatically't'o apply an object to the warp, while passing through the slasher, which object will engage" means carried by the loom for stopping theloom" automatically as the portion ofthe warp, carrying the object, passes through the 100m.

More particularly, it is an aim of the irivention to provide an attachment including adevice mounted on the slasher andactuated by the cut marker shaft thereof for cutting apiece of a drop wire of the stop mechanism of the loom to be engaged and actuated by the tape while passing with the warp through the loom, for releasing said drop wire'to permit it'to' move to a position for actuating the stop mechanism for stopping the 100m.

However, it is verydifiicult and practically impossible for weavers to'watch' Figure 7 is a top plan view of the same.

Referring mor particularly to the drawings, wherein like reference characters designate like or corresponding parts throughout thedifferent views, l2 designates generally a portion of the entrance end of a conventional slasher, including 0 a portion of aside member I3 of the slasher frame, a portion of the cut marker shaft M, which is' connected by gears, not shown, to the delivery roll l5, at the front or entrance end of the slasher. These parts are of conventional merely to better illustratethe application of the invention, designated generally Hi. The attachment l6 includes a portion, designated generally [1, which is associated with the slasher I2, and

, which includes a frame IS, the base [9 of which is disposed above and adjacent the warp 20 and near the delivery roll l5, as best seen in Figure 1. Referring particularly to Figures 6 to 11, the

frame I8 is provided at one end thereof with uprights H which form the ends of a U-shaped member 22, the intermediate portion of which is fastened to the upper side of the base l9 by fastenings 23, as seen in Figure 9. A roll of adhesive tape 24 isdisposed between the uprights 2| and is mounted on a shaft 25 which extends outwardly through said uprights and which is provided with a head 26 at one end thereof. A coil spring; of-the expansion type; 21; is-mounted onthe shaft 25, and has one endlbearing against the head 26 and its opposite end bearing against the adjacent side of the roll of tape 24. The upright 2| through which the spring 21 extends, is

provided with an enlarged opening 2-6 for-accom modating the spring, and the other upright Z I tion on the head by means of detachable strap members 55, which are formed of metal, and which are fastened at the lower end of the head 49 and which are provided with inturned upper ends which engage against the upper side of the solenoid 52.

A core 56 of the solenoid 52 is slidably mounted inthe bores, 45,5 and 53 and is formed of sectionsconnected, as seen at 51, in end to end relationship. The lower section of the core 56 has atrectangular cutter 58 at its lower end. A rod 59"extends transversely through the. lower sectiorvof 'thecorez56. The ends of the rod 59 project outwardly through the slots 41 and are atis provided with a smaller opening-29- in which.a'..15.,tached. to the lower ends of contractile coil portion of the shaft is journaledz Afmit and washer, forming abutment means 36 are adjustably mounted on the opposite; threaded 'end of the shaft 25 to form a stop for an expansion coil last mentioned upright 21 to combine with the" springlf to resist the rotation'of"the roll"oftape= 24', for a purpose which will hereinafter become apparent.

The base'l9 -is provided-with*upright bearing stands "32'," adjacent its opposite end, having baseportions which are connected to the base l9by additional fastenings 23., The bearing stands-32 are" disposed in transversely spaced relationship tcr'one' another and are provided" with" alined openings 33 in which a shaft 34 is journaled. A roller 35iskeyed to the shaft 34 and disposed between" the bearing stands" 32? 'I'he-roller 35 is springs 66,1.the upper ends of which are attached to fastenings 6| in the head 49 for normally holding the-core 56 in a raised position, as seen inFigures 6, 9 and 10.

Between the member 22 and the standard 44, the base |9 :isprovided with an openingor recess 62 inwhich is disposed: a :receptacle 63nwhich is adapted: to contain water-and which is providedv withan'openingfiminthe top thereof, and ad- 5: jacent the standard 44. A roller :65 is journaled in'the receptacle. 63 and projects slightly through thesopeningi 64. A-. rod 66 extends over the top of". the) receptacle-63;. adjacent the roller 65, and

between: the-roller: and the member 22. As best .39 seenin: Figure 9; the free end of the tape of the roll is passedzunder the -rod 66, over the roller 65, through the opening/46,. under and partly around the-roller-35, and (is wound on the roller 36;.

Alshaft 61 i's'r'provided' witha" head 66, atone end thereof, which is-csecured to the outer side of one-ofi'the bearing stands 32; A gear 69 is journaled on the-innerend of the shaft 61 and a ratchet wheel-.10; which is fixed to the gear 69, is r journaledon the: intermediate portion of, the

shaft 61. A leverfl l: is pivotally mounted intermediate off its endsaon'the shaft 61, on the outer side-of the ratchetwheel 16; The parts carried by: the: shaft 61 are detachably retained in positions-thereon by means of a removable collar 12 5-whichis: secured to the outer end thereof by meansofa SGUSCIBW'TS'; As seen in Figure 6, the teeth of. the: ratchet wheel 16 are all curved or inclined in" a counterclockwise direction. A spring I pressed pawl 14 is pivotally connected to thelinner-endof the lever 1|, or to the end thereof adjacent to the: standard 44 and is disposed to; engageithelteeth of the ratchet, wheel 10, so astoturn theratchetwheel when the lever 1| is. swung inya clockwise direction; as seen in 5 Figure: 6; and to ride over the teeth of the ratchet wheel" when-thelever1-| is swung in a counterclockwise direction. As best seen in Figure 7, the head 68 is: extended in a direction away from thepawl 14-and'a spring pressed dog 15 is piv- 70 otallyconnectedto the'free end of the head 68 and has its free: end disposed to engage selectively-in the teethof theratchet wheel 10 to prevent the: ratchet wheel from turning in a counterclockwisedirection when the lever 1| isthus the head 49 and the" solenoid is retainedinepositurned. Likewise, the dog 15 isayieldably mounted to ride over the outersides of the teeth of the ratchet wheel I when it is being turned in a v clockwise direction. As seen in Figure ;11 a

pinion I6 is. keyed to oneend of the shaft .34 and disposed to mesh with the gear 69 for turning the roller 35 in a counterclockwise direction when the gear 69 and ratchet wheel III are turned in a clockwise direction for drawing the tape 24 from the roll which is disposed between the uprights 2|. I u e The frame I8 may be supported in any suit: able manner, as by means of a bracket IT, as

seen in Figures 1 and 2, which is attached to the which engages theshaft .89, near its opposite end. a Set screws 84 are provided for adjustably keying the levers 82 and 63 to the shaft 20. The cut marker shaft I4 and the cam I8 turn in a counterclockwisedirection, as seen in Figure 2, or in a direction as indicated by the arrow 85, in Figure l, and the free endof the lever 85 is disposed to be engaged by the cam I8. The lever 82 is provided with a longitudinal slot 85, atits opposite, upper end through which extends thelthreade d end. of a link or connecting rod 81. Said threadedend is provided with nuts 88, which are disposed'one on either side of the upper end of the lever 62 for adjustably connecting the rod 87 thereto. The nuts 68 are disposed sufiiciently loose so that the threaded end of the link or rod 81 can slide relatively to theslot 86. The opposite end of the connecting rod B'I is pivotally connected to the end of the lever ll, opposite to the end thereof which is provided with the pawl It and which end is normally disposed below the horizontal axis of the shaft 51, as best seen in Figure 2. A contractile coil spring -89 is attached at one end to the lever 82, adjacentits upper end and is anchored to the side I3, at its opposite end, for urging the lever 82 to swingtoward the frame I8 for turning thelever H in a clockwise .direction, as seen in Figures 2 and 6.. It will thus be apparent that a push will .be exerted on the connecting rod 8? by .the action of .the spring 89 while a .pull will be exerted thereon by the action of the cam I8 rocking the lever 83. in a clockwise direction, as seen in Figure 2,.to there.- by rock the shaft and the lever 92 in a clockwise direction. Q

A switch 90 is mounted above the cut marker shaft I4 by means of a bracket 9I which is secured to and depends from the member I3. .An electrical conductor wire 92 leads from a source of electric current, not shown, to one post of the switch 99 and a conductor wire 93 leads from the other post thereof to the solenoid 52. A return or ground conductor wire 99 leads from the solenoid 52 back to a suitable ground, not shown, of the source of electric current. The

switch 99 may be of any suitable construction and which is normally open to interrupt the circuit to the solenoid 52. An arm 95 projects outwardly from the switch 99 and is adapted tobe pivotally mounted to swing downwardly, when pressure is applied thereto, for closing the switch 'edge of the crank 96.

and when released is adapted to return" to its raised position for again opening the switch.

Any conventional construction of switch possess- ,ing these features may be employed, as no claim is made to the switch, per se.

A crank 96 is provided with a hub' 91 which is turnably mounted on the shaft I4 and which is disposed between collars 98, which are secured to the shaft I4, for preventing'the crank 96 from and which is disposed adjacent to the crank 96. A stud or pin IUI projects laterally from the arm of the crank 99, adjacent its free end, andis arranged to engage against the rounded, back It'will thus be obvious that thecrank99, as it turns in a counter clockwise direction, as'seen in Figure 3, with th'e shaft I4, will engagethe back edge ofthe crank 96" to swing it upwardly from a depending position slightly past an upright position, or slightly past the position, as seen' in Figure}, aftirwhich the crank '96 will be swung down wardly' in a counterclockwise direction by gravity back to a depending position. The lever 95 of the switch 90 is disposed in the path of the arm of the'crank 95 to be engaged thereby dur-.

.passing through the tape 24 will cut a piece therefrom corresponding tol the shape of the lower end 58 and will carry this piece of tape I92 downwardly through the lower end of'the bore. 45 and apply it to the warp 20,,as seen in Figure 4. An opening I03 will thus be formed in the. tape 24, as. seen in Figure 7, which, however, is not sufiiciently wide to weaken the tape 24 sufliciently so that it cannot continue to be wound onto the roller 31. As previouslypointe'd out, the portion, of the tape which is cut out to form thepiece I92 will have been just previously moistened on its coated side by theroller 65 so that it will readily adhere to the warp 20. After the solenoid 52 is deenergized the springs 69 will react to return the core or plunger 56 to a raised position, ready for another downstroke when the solenoid 52 is again energized. Between the downstrokes of the core 56;v the lever 82 is rocked outwardly by the cain 'I8enga'ging the lever 93, as previously explained, to move the levers 82 and H to the positions, as seen'in Figure 2, so that when. the. cam I8 rides under the free end of the lever 83 the spring 89can react to draw the lever 82' inwardly for exerting a pushon the connecting rod 81 to turn the lever H and the ratchet wheel. I6 approximately a quarter of a turn in a clockwise direction. This will advance the tape 24 toward the roller 35 to position another portion of the tapebeneath the cutter 58 to be cut by the next stroke of the core 56. The roller 35 is provided with the felt periphery 36 for frictionally engaging t e, apeand i ri h r so f i n y nd ld b i hii f eie l i i i isai i iui inf theoppds e direction to thelroll'er 35 for' Wind n l iaziiih wt, bi i m fi i im the setscrewsWZ 'may he looseneditoallowfor? the tape being wound ontheirollerffl and so' that said roller" canbef inovedsliglitlyf away from M a he ait se ri h fi l 4; eve i s n w wly and it will be apparent that the: niechar'if" ev o l r ibei en: e dj st d 9- justingj the cam lit by the set, screw," l 9 and the cranlg 93 by its seij 'screw lg to cause the parts," previously described, tov be operated at the desiredtime during [@chl 'revohitioh of the shaft wh h s nq ioes e ir??? am: tional cut mark ng me n not shown, of'the slasher l2 which applies a mark, by means of dyejto the WarpZB;
