Textile' 'industry necessitates. the usatsyms free from defects (thick placesor beads; staples,

pads, kinks; double'threa'ds; difierences ofztwistsy prejudicious to theproper operation-of the ma ohinesr utilizing them; and twtha appearance. ofv

the fabrics obtained.

It is therefore necessary to clear either upon spinning, or uponepooling;

Use is madefor-that purpose of apparatus: called clearers; these apparatusare usuallypros; vided' with: slots through which. the; yarn; passes, and 1 are constituted;- for that, purpose: qeitheri-iby two paral-lel blades arranged in oneand the-same planeandthe-spacingiapart of which is adjusted as desired, or byatdisc': having :IIadiaI- slotsof different widths, or; finally; by :two;-:b1ades arrangedinoneand theisame plane; andgfiorming". together-a v shaped-slot; j=- 1 r ""-j; I t

These apparatus: have thiainconvenience that they clear the yarn only in'oneplana'gthus producing'ia" kindofrollingwhich' ensures but-an imperfect clearing.

It has .been' attempted, to clear yarns" two different planes, by compelling. them to-successively pass between: two sets ofz blades-having two" slots at right-angles ,to eaclr other and giving. in projection on a plane parallel to the blades, an orifice-of trapezoidal: shape-I closelyapproximats ing-a square'shape: I I

I But the distance which: mustbe left between the two sets of blades for allowing the insertionof the yarn isusua'lly such that it allows the yarn to tum over while tit is-passing. between thetwo slots, so'thatit: is subjected only-to' two successive rollings and that clearingzis still-far, from perfect. q i I v I I I The present invention has for its object a de-' vice-so arranged as-to avoidthese inconveniences and to ensure: a complete clearing of, I the yarn, by' passage; .not through a' slot,,=or' through two slots spaced apart, but through :an' oriflcetof ad' justable cross-section constituting a' die ordlak-W- piate capable "of cofitrolling the 'diameter of the yarhtojb'ecleared I I f w W The; deviceflaccor ing to the invention comp se twp .sm l ffll'at s; ch" biqv' id with mac -ans fltted against each"other", st that both notches are'located'opposite each other and form aii-orifi'ce in which the yarnjis engaged. I I I During normal operation, these small late's 'are lockedagainst each otherin the desired position, so that the device is the equivalentof a die or draw-plate arranged inqthe plane of contactoi both plates, and stops any defect giving. to the these yams,

.; In the first form, of construction; Fig.1 1-: shows asupport 1 having two slots: one, 2, verticaLIthe other, 3, slightly oblique. I I

A smallplate 4 ('Fig. 2) has. a .r ightang1ed notch 8, forming: two of the sides oithe square, and-carries two pins or studs 5, 6 adaptedtto be fitted the slot 3 and 1 to slide inth-ej latter ;1 in this plate 4 is also provided a slot '7; parallelwto the diagonal of the square.;-

Fig; 4 shows a smallplate l lzI carryingguon one of its faces, a resilient blade 9, and, on the other face, two pins or studs 12, 13.

In position of assembly, the pin, 12 passes through the slot 7 and extends into the slot 2, and the pin 13 fits into this slot 2.

The blade 9 is provided -with a right-angled notch 10, adapted to cooperate with the notch 8 in order to constitute the two other sides of the square. i 4 I The pin 12 is provided with a screw-threaded part adapted to receive a locking nut 14.

The operation is as follows:

The small plate 4 is fitted against the plate 1 so that the pin 12 enters the slot '1 (Fig. 5);" The blade 9 is bent so as to compensate for the thick 1; ness of the plate 11 and to exactly iit against the plate 4. The entire structure is fitted-behind thei'f support 1, so that the pins 5 and 6 enter the slot" f 3, and the pins 12 and 13. enter the slot 2; .11; If a vertical movement, for instance an upward movement, is imparted to the pm I 12 this causes-a the upward sliding movementofthetwo members 1 device.

I The inclination" of the slot 3 compelsthe plate 4' to slide towards the left of the draw'ings, and

owing tothe inclination of the slot-"7 parallel to' the diagonal of the-square; this slidingmovement causes a displacementl of the notch 8' relativelyto the notch' 10-paralle1flto one of the diagonals of the square, so that both 'notehesform-asquareof increasingydimensions. I Y

Rev'ersel'y', when the pin'12 is'move'd downwardly, the dimensions 'of' the square decrease. lL When the cross-section of {the square is-zadjusted, the nut 14 allow's of clamping the 'various members against each other and'f to lock the This nut can be so arranged that it can be venting any fraudulent use. h In order tofacilitate theadjustment," a scale, forinstance; can be traced onone ofthes'ides of the member 1, and an index movingover this operated only b -means of a special wrench pre- 7 scale can be securedto one of the pins 1'2 or T3.

I support in position.

For passing the yarn, it sufiices tomove the spring or blade 9-away from th'e member-4 by a; slight backward pressure; to then cause the yarn to enter the interval formed betvven the 't'Wo members "thus spaced apart; tobring it 120 the bottom of the angle '10, 'and to letthespring or blade come back again against the member 4; The relative displacements of the'notches 8,10 can be rendered more or less rapid by moreor less incliningthe slot 3 relatively to the vertical.- It is to. be noted' that by giving to thisslot" a relatively small inclination, the displacement'caln' be rendered very slow; and,c0n seq11ently, a very accurate adjustment can-be efiected. i F

In the secondform of construction, the-notcl'i' 10-is provided inthe support-15 of the apparatus. This support is provided withside lugs '15: m" which are formed holes 15 for securing the'said Its front face carries an oblique projecting guide-wand, in alignment with the axis of this guide, it also carriesa pin17.

' With thesaidguidecooperates an adjusting-"bar 18 provided with a slot 18 aQ having the same obliquity as the guide 16. lii position of assembly (Fig.8) this-guide extends into the slot 18d, and

Finally,:'the plate-19 has a notchcl9 yparailel to the diagonal of the square and through which the pin 12 passes. 1 p Inthese conditions, if the adjusting bar 18 is vertically moved, upwardly for instance, it slides at the sametime on the support 15 towards the right 9f; thgdrawings, at the same time as the plate 19.

' The l'atter is then compelled, by the pin 1'7, to move parallel to a diagonal of the square orifice,

y the crossfsection of which diminishes.

Reverseiy, this cross section increases when the: adjusting bar 18 is moved downwardly.

'Theadjustment-is facilitatedj'by apscale 18c" carried by the adjusting bar '18, andthe graduationeom 'esponding togthe desired adjustment is read for instance opposite the lower edge of the;

plate19. When'this adjustment is effected; the apparatus is locked,- for:instance by'means ofa lock nut- 20 screwed on a screw-threadedextension of "rmsmu; zo-rests on the plate iii-"through the: intermediary'oi ai'libearing washer 21 and 'of a' Grover washer- 22. The washer 21 constitutes moreover a socket 21a whichsurrounds-the nut 2'0 and: preventsacc'ess to be had theretoifother-w wise {thanwith a? 'wrerich23' of suitable shape thusrenderingany fraudulous use'impossible.;

It is to be understood that," without departing from the scope'of the" invention, the square orifice can-be replacedbyan orifice having the shape o'f any quadrilateral; for instance of a triangle of any shape.
