To all whom it may concern Be it known that I, GEORGE E. SPOFFORD, a citizen of the United States, residing at Newmarket, county of Rockingham, and State of New Hampshire, have invented an improvement in Slashers, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

The invention to be hereinafter described relates to Slashers for treating warp yarns or threads and winding them upon a beam to be afterward placed in the loom, and more particularly it has reference to means for insuring a proper relative position of the warp threads as they are wound upon the beam.

As Well understood by those skilled in the art, the slasher is designed to size or treat each thread of the warp, to dry the sheet of warp after. sizing, and then wind the dried sheet of Warp onto the warp-beam in such manner .that the threads will properly unwind therefrom and pass to the Shed forming and cloth making devices during the weaving operation. To these ends the warp threads from the desired number of section beams are led through the sizing device and thence tothe drying medium, such as heated cylinders or drums, and, as the sizing and drying operations tend to cause the threads to stick together, certain splitting or separating barsare .used to divide the dried warp horizontallyin-to several sheets. The divided warp is then passed through the slasher comb, the teeth of which divide the warp into a series of flat bands or sheaths as they are termed, each band or sheath, being formed of a plurality of warp threads arranged one above the other in a substantially vertical plane, and the several bands or sheaths thus travel toward the beam in substantially vertical parallel planes. Since the axis of the beam is horizontal, each band or sheath must turn through an angle of substantially 90 in order that the threads may be wound upon the beam side-by-side in a single sheet.

From the slasher comb the warp passes between evener or smoother bars and then about tension rolls from which it is delivered to the beam in the form of a singlesheet.

Between the slasher comb and the warp beam, however, the warp threads are liable ,to become relatively disarranged or to roll over one another so that one or more threads on the warp beam may be crossed. or overlaid by others. As a result of this irregular winding much trouble is frequently experienced when the beam is unwound in the loom, all as well understood by those skilled in the art.

tion into practical efiect, it being understood that features of structure and details may be modified and changed within the true scope of the actual invention which is defined by the claims.

In the draWings:-Figure 1 is front or end view of a slasher looking toward the right, Fig. 2, unnecessary details and parts being omitted for better exploitation of the invention; Fig. ,2 is a section on the line 22, Fig. 1; Fig. 3 is a detail showing features of the present invention in side elevation on -an enlarged scale, and Fig. 4: is a cross-section showing one form of the arranging comb that maybe used and its preferred relation to the warp threads.

The general character, construction, and operation of the slasher may be the same as now in general use and being well under-- stood by those skilled in the art, it will not be necessary to Show and describe the Section beams from which the warp threads are taken, the liquid or sizing device, nor

the means for drying the treated threads.-

Only three of these splitting or separating bars are shown, butit is to be understood that the invention is .not restricted in this respect, and that any appropriate number may be employed to properly separate the warp threads, and such bars may be supported in any desired manner,-as from the mainframe 1 of the machine.

.The slashercomb 9 may be of usual construction, preferably of the well' known ex pansion type,- having the teeth, as shown,

which divide the warp into a series of bands or sheaths, the threads of which are substantially'in a vertical plane one above the other.

i and smoothing bars 11 and 12, two of which I Mounted in suitable sustaining means, such asthe brackets .10, are the flattening are shown, although it is to be understood that any appropriate number of such bars may be employed. From the slasher comb 9 the warp is delivered to the action of the flatteningand smoothing rolls which turn or flatten the bands or sheaths into hprizontal position, and from the flattening and smoothing bars'the sheet of warp passes to g the tension rolls 13, 14, 15, as indicated in Fig. 2. These tension rolls. may be of any appropriatecharacter and. number, and I may be supportedby any appropriate means Asshown, the roll 13 is of larger thebarrel 19 having, the heads 20; The Q warp beam may be appropriately mounted i on the shaft 21 sustained in the'bearings 22 employed for rotatingthe beam to wind the "we. thereon, are well understood by those carried bybrackets 23 projecting from the mam frame, and suitable means may be warp thereon. 1 The parts so far described may be all as usual, and-since they, as wellas the means for rotating the warp beam to wind the familiar with such machines, no further explanation or illustration of, such devices is v.

deemed-necessary.'

Ais thebands or sheaths of war, threads pass from theslasher comb to an between the flattening and smoothing bars the I bands or sheaths are turned into'horizontal position, and during this turning movement the threads are "liable to become irregularly arranged onto roll over each other to a.

. greater or lessextent. This same tendency nt even after the threadshave passed between'the flattening and smoothing bars and while they are traveling from such bars to and around the tension rolls and toward the warp beam, so that even should the bands or sheaths turn to horizontal position in the same direction and without disar- 'rangement of the relative position of the warp threads due to said turning movement, such warp threads are still liable to become moreor less .crossed or irregularly arranged before. they reach and are wound upon the.

warp beam. In either case, and quite regardless of how the warp threads become thus irregularly related as they reach and are wound upon the warp beam, this condi- 1 tion of the warp threads, when the beam is placed in the loom, forms draws which interfere seriously with the proper weaving operation, and one of the purposes of the present invention is to provide means to effectively prevent the occurrence of such irregularity and insure that .the threads shall be wound upon the warp beam in a single sheet and in uniform order side by side. As one form of means to these ends the present invention contemplates separating the warp threads horizontally by a comb disposed closely adjacent the warp beam, and after the threads have passed the tension rolls, so that no matterhow much crossing or irregularity of threadsmay have occurred between the slasher comb and the last' ofthe tension rolls, the comb acting upon the threads just before they pass onto the warp beam, will insure their uniform arrangement side by side as they are wound upon the beam. In the form of the invention shown, the said comb, which for identification maybe referred-teas the arrang ing comb, is mounted to maintain itsrelation with the sheet of warp asthe warp beam increases in diameter and is preferably movable to and from operative posi-" tion to facilitate'dofling, as will hereinafter more fully appear.

The arran' g comb comprises the comb bar 24 from" which project they teeth" 25, F1 .--2,3, a thesaid teeth beingsuitab yfspa ced-apart'to receive between them v .onefor more warp, threads 26; The arranging comb is sustained in close proximity "to the-'wa beam and between it andthe tension ro ,so that, just as the warp asses onto'thebeamthe teeth ofthe'com will separate and arrange the warp 'threads in uniform relation side by side, and as one form of ,means for .thus'sustaining the arranging comb the-end portions of the comb I bar 24 may be extendedto engage bearings I 27 in the, arms 28, pivotally supportedjfrom the machine frame. In the construction shown as a good practical embodiment. of the invention, the supporting arms 28 are securedby means of aset screw 31 or otherwise, to arock shaft 29 mounted in suitable supports 30 rising-from one ofthefl atten- Lassa Y beam, the latter increases in diameter, so.

that thepath of the warp from the tension rolls to the beam varies in inclination or direction, and the described mounting of the arranging comb upon the swinging supporting arms 28 thus permits the comb to move with the sheet of warp in a direction transverse to the axis of the warp beam and maintain its operative relation with the warp sheet during the variations in diameter of the load on the beam. It is to be understood, however, that while the particulars of structure thus far described furnish a good practical form of the invention, the invention itself is not restricted thereto, but

in its broad character embraces various,

modifications and equivalent means for sustammg the arrangmgl comb in operative relation to the warp closely adjacent to the warp beam. I

In dofling, it is desirable that the arranging comb be moved out of operative position and to this end the supporting arms may be turned upward, as indicated by the dotted lines, Fig. 2. At such time, an arm or lug 32 secured to the rockshaft 29, as by the set screw 33, Figs. 1 and 3, contacts with an appropriate stop, such as the edge of the flattening and smoothing bar 12, to main tain the arranging comb in raised or. inoperative position. Obviously the means for permitting the arranging comb to be moved from operative position during dofi ing may be variously formed.

The teeth of the arranging comb are preferably provided with the pointed ends whereby as the comb is brought into operative position the teeth will more readily insinuate themselves between the threads of the warp.

Itoccasionally happens that fiufi or a knot may be carried by a warp thread'as it approaches the arranging comb, and since this comb is comparatively fine. such fluif or knot may not readily pass between the teeth of the comb. To meet this condition and guard against breakage of threads, the comb is preferably" arranged or adjusted so that when in operative position, as indicated by Figs. 3 and 4,the face 35 of the teeth 25 will be at an obtuse angle to the path of approach of the warp, see Fig. 4, the construction and arrangement being such that should a knot or piece of flufl? or the like be carried by a' warp thread against the inclined face 35 of the teeth, it will cause,

the warp thread to move outwardly until the knot or flufi or the like passes over the end of the teeth, whereupon the thread will The arranging comb is shown as preferably comprising the bar. 24 and attached teeth 25, but it is tobe understood that the invention is not restricted thereto and that any preferred comb may be employed. In the illustrated form of the invention, the comb rests or bears upon the sheet of warp threads and is preferably supported thereby so that as the beam load increases in di' ameter the comb will be moved in a direction substantially transverse to the axis of the beam, its teeth being thus maintained in intersecting relation with the warp sheet as the path thereof changes. As the teeth. of

the comb are preferably to remain in submeans be employed to control this angular relation throughout the winding operation. Various means may be employed to this end, and as one convenient and practical form thereof, the present invention contemplates a controller or bar connected to the arranging comb and bearing upon the warp sheet.

In the form of the invention illustrated, the controller comprises a rod or bar 36 extending to a more or less.,.extent transversely of the sheet of warp and connected to the arranging comb. In the present instance this connection comprises the split sleeves 37 which embrace the comb bar 24 to which they ma be adj ustably clamped by the set screws 8. The controller 36 is adjustably secured to the sleeves 37 and to this end is preferably formed with side arms 39 and end extensions 40 which engage suitable sockets in the split sleeves 37 to which they may be adjustably secured by suitable llQ oration in a manner to insure the proper passage of any knot or find carrying warp thread over the end of the comb teeth.

From the construction described as one form of the present invention, it will be noted that the warp threads, just prior to their delivery to the warp beam and after the various means for arranging the warp a single horizontal sheet in the slasher have acted, are separated and arranged in parallel, relation side by side, thus avoidingany liability of overlaying as the'threads are wound upon the beamand the resulting objectionable draws when the'threads of the sheet in parallel relation side by side are taken from the beam in the loom. I It will be noted'also that in preparing the warp for drawing in, that'is- 'assing the individual threads in regular ordbr the heddles or shed forming means, the lease forming comb may be engaged with the vvvarp closely'adjacent the arranging comb through before the warp is'taken from'the slasher,
