, Application filed May'7,

Be it known that Gnonen citizen of the United States, residing at 'us eful Improvements in Attachments for.

Augusta, in the county of Richmond and State of Georgia, has invented new and Slashers and Finishers, of which the-following is a specification.

The object of the invention is to provide an attachment for the slasher and finisher commonly used in the textileart whereby the warp threads may be so operated upon that those lying in the 'selvage are ofi'set at specified points, thus providing a gap in thewarp which will serve, in conjunction with a stopping device appliedto the loom,

to positively stop the latter. Warps runin the ordinary way will not accomplish this result. The improved device herein shown and described works with the usual cut marker and each time a cut mark is made with die in the usual way, the improved 'device operates upon the selva-ge warp threads to ofi'setthem. The use of the device relieves the operator of the trouble of watching for out marks and in this way allows a ting referred to.

one operator to increase the number of looms which he or she may run and the operator can devote all his or her attention to the general stopping caused by the warp threads breaking.

Another objectof the invention is to pr0- vide means for the purpose specified whichis 811111319111 construction, durable and ef-;

fective in operation and inexpensive to manufacture and apply.-

Other objects appear in the following description'wherein the invention is set forth in detail. The invention is illustrated and described in a specific embodiment, to which,

however, it is not to be restricted. The

right is reserved to make such changes or alterations as the actual reduction to prac tice may suggest'insofar assuoh changes or alterations arecompatible in spirit with the annexed claims.

Referring to the drawings, there is show'n' v in- Figs.-1iIand 2 a slashing and finishing machine which comprises theusual sizing apparatus 1, theheated drum 2, the usual guide rolls 3, the leash-rods 4 and the removable beam 5. This" apparatus just de scribed follows the ordinary well-known construction, the warp being led from ape".

propriatebeams (not shown), thence to the SlZQebOX 1 thence lover heated druin'2 and: around same to the uppermostfof the fguide rolls 3, soi that-it completely encireles the if drum, thence around theother guide rolls and around the Qleashrods toremovable beam-'5. The-warp threads inthis'apparatus are of course separated between "the leashing means and. the beam by an appro-' V priate combbut the latter-forms no partof the present invention. Thepresent inven-I tion resides in means :for offsetting the outermost warp threadson-one-edge, so jtha't a gap-of specified length 'will occur in the "selvage on one side. "For the purpose or. 7

providing means for'automatica'lly stopping the loom when'this gap appears ,onthe latter, the gap is formed where the usualf-cut mark is made with an appropriate marking apparatus or die and the improved apparawe can be used with or without the die marking apparatus. The referred ."to

indicates that a point inthe warp has been" reached where acut is tobe made.

The guide rolls are of course put in'motion in the usual way and that rolleron't'he extremeleft' hand end of the apparatus has attaohe'dto its shaft a worm wheel 6 meshing with aworm 7 carriediby the shaft '8to 'ioo i which power is transmitted byfappropriate 7 means (not shown) This shaft Bfisan; essential part of the us'ualform' of slasher and the improved device is operated partly by this shaft and partly by 'theshaft' 9 which is-also an essential' 'part of the usual form of slasher; Shaft?) terminates adjacent the comb 10 and carrieson its extremity agea-r 11, this gear meshing with-a gear 12 which is mounted onone' extremity of a a 60' diagrammatic view to illusshaft 13 journaled in appropriate bearing standards 14 carried by the frame of the slasher. I The'warp threads pass between the teeth of the comb 10.and over the roller 3 which carries the Worm gear 6 and the selvage warp threads are operated upon by the improved devicebetweenthe comb and the roller 3 this device operating at specified intervals indicating that a certain number of yards of warp have passed this point.

The warp threads having been treated in the size-box andpassed over the heating 1 drum 2, if the outside threads be pressed r in after such operation, the sizing will cause of an arm 19 which is slidingly carried in V the legs of a U-shaped'member 20, the latter:

being carried by an appropriate bracket 21 by means of which it isseparated on the frame of the machine. v,

The U-shaped member 20'is disposed in Y I the direction of the width of the machine-- that is, in the direction of the length of the guide rolls and the combs-and it is provided with an upturned supporting arm 22 at whose upper extremity a stud 23 is attached, the latter serving to support the double flanged pulley 24 whose axis is dis:

posed in the direction of the length of the '7 frame of the slasher-that is, in the direc- 4 tion of the length of the shaft 8. The pulley 24 is disposed between the-U-shaped member 20 and the arm' 23 and carries on that side facing the U-shaped member an eccentrically disposed boss or'projection 25 1 a which is provided with a wrist pin 26 with latter shaft carries a double flange pulley. the latter,

which one end of a link 27 pivot'ally connects.

The pulley. 24 is rotated through the medium on the shaft 8 and to that end the 28' over which a belt 29 is turned, being turned also over the pulley 24. Ohviously when the shaft 8turns rotary motion will be imparted tothe pulley 24 with, theresult that the link27 will be reciprocated and this link is designed to reciprocate the bar 19 at certain specified intervals of time during the passage of the warp threads from thecomb to the roller 3 f To this end there is mounted on the arm 19 a bracket member 30 which is formed with an upturned ear 3l to which the remaining end 1 draw formed with the of, the link 27 is pivotally connected. This,

bracket 30 is formed with any extension 32 extending in the direction of the length of the arm 19 and toward the pulley 24, the

"bracket being provided with pairs of spaced lugs 33 and 34 which straddle the arm 19 on the upper edge. The bracket 30 is mounted so as to slide along the arm 19 as the pulley is provided a spring 35having one'end con nectedto a laterally extending bracket36 formed with the U-shaped member 20. The other end of this spring connects at an intermediatepoint with a small red member 37 which is made preferably of a single piece of vwire and formed with an eye 38 with which the end of the spring 35 con nects. One extremity of this rod member 37 is pivotally connected to the arm 19 at 39 but the other extremity of this red member is free. Obviously thespring will serve to the latter contacts with one leg of the U- shaped member 20 I moved against the tension of the spring to space the lug from the said leg and to force the roller 16 inward where it-will contact,

with the selvage thread of the warp.

Pivotally mounted on the arm 19 on one which is engaged by the free'e'nd of the rod member 37 to keep the nose of the pawl depressed, the tail and nose of the pawl. being on opposite sides of the pivot connection.

'The pawl is designed to be engaged on the nose by a lip 42 formed on the extension 32 of the bracket 30 but this lip may only engage the pawl when the nose of the latter is raised and means'hereinafter described is provided for raising the'nose. The lip 32, however, with the periphery of the toothed disk 43, the latter beingrotatably mounted on a stud 44 carried by U-shaped member20. This disk is provided on its one side with a plurality of axially disposed pins 46 designed to operatively engage a lever 47 carried by a register or counter 48 whichis supported on a bracket portion 49 also formed with the U-shaped member20. When the pawl 41 has its nose out of engagement with the lip 42 of the extension 32 of the bracket 30, the bracket willonly slide backward and forward 19 as the pulley 24 turns, the spring 35 0b and the arm will be is always operatively connected an upstanding support 45.

along the arm" the arm 19 inward until the lug 40 on V a side thereof thereis a pawl41 the tail of viously serving'to keep the arm IQ-"inaposition whereits :lug. 410 "contacts with one leg of the U-shaped member. By'the provision of the free "extending en'd' of the rod 7 37, :the' spring: also serves to. keep the pawl passed the roller 16, however, the arm 19 is designed to be forcedin toward the Warp until the roller contacts with'the outermost warp threads 'and -forces'them in. toward adjacentthreads to provide the 'gap 15 pre viously referred to. To this end there is mounted :on the shaft'13 a cam "50 the periphery of which follows the outlinelof a spiral, thus providing a direct dropffrom the highest pointto'the lowest point of the cam,"as indicated at 51 in Fig. 5. Playing on the periphery ofth'is cam'50 there is the extremity of one arm of -a bell crank lever '52; Thislever is pivotally mountedpas at 53, ona bracket 54' formed with one of the bearing supportsl. "The extremity :of-the remaining arm of this lever 'pivotall-y con} nects with one end of a bar 55, the other extremity of this bar passingslidablythrough a slot formed transversely through the arm 19. That end 'of'thebar 55 passing through the arm-19istapered ofi' as'indicated at 56 and this tapered end or-nose of the bar passes under the nose end'of the pawl 41. Obviously as the shaft 13 turns the cam 50 is turned with it and the bell crank lever 52. is rocked on its .pivot 53 against the pressure of a spring 57 which is, attached on the bracket 54 and bears against-thatarm of the lever 52 to which the bar '55 is connected. The spring-serves to keep thebellcrank lever in contact withthe periphery of the cam and thus provides for; the rocking of the lever during the movement "ofthe cam, this rocking of the lever, of course, lmpartinga I'BCIPIOCELtIIig movement to the bar 55 causing the latter tomove in and out through the slot formed in the arm '19; When the bell crank lever is on-the highest point of thecam, 1 the bar- 55 reache's""the limit of its movement through the arm 19- inthe directionof the disk 43.- In such a position of the bar the under edge of the pawl 41 adjacent the nose is engaged by the tapered end of the bar andraised so 'thlat the nose'reaches' a point where it mayfbe engaged by the lip 42 of the extensionof the bracket 30." When the bracket 'moves forward due tofthe turning of the pulley 24, it serves," byengagement of the'lip 4:2 with the pawl-41, to carry the arm' 1-9--forwardwvith it ag'ainst' the tension of the V againstthe adjacentl'threads, the sizing-0n adjacent threads causing'them to a'dhere'together andpro'duce the gaps 15. When the arm of the bell crank] lever drops to the lowest "point on the cam 50 as indicated at 51, the bar '55 is withdrawn from its former position and the pawl 41 is permitted to assume its normal'position, the spring v35 V at this time drawing the arm 19 backward and raising the tail and depressing the nose of'the pawl; The arm '1 9 thus remains inert until the cam 50 again effects the operation ,of the 7 bar 55. jOb-viously tthe angular' velocity of the shaft-(=13 is low and its speed ratio with reference to the speed ofthe shafts on other parts of the slasher is {such that the bar 55 is operated at the proper injtervals to raise the roller-16 to produce the gaps 15 at the=desired pointson the warp.

Aftertheiwar'p has been prepared in 'th'e I slasher and finis'her, as before described, and has been wound upon the-beam 5, the beam is transferred 'FtO the;loom, as is'the usual practice, and thegap's formedfiin the'selvage edge of the warp permit the actuation of a jmember traversing the 'sel'vage edge, this member dropping each timeajgap is encountered, and, being operatively connected "to the loom stopping mechanism, serves-to bring theloom to' a stop; Such" a member and its means for operating the loom stop are shown in the applicants copending application, filed May 13, 1920 and bearing SerialNumber 381,072
