ROCAMORA, or SAZBADELL, SPAIN MACHINE non CLEANING; nvrrnovme, AND sorrnmne WOOL AND o'rirnn TEXTILE i MATERIALS i Application filed February 1,'1929,' Serial No. 336,762, and in Spain November 20, 1928.

My invention consists of a machine for improving, soittening "and cleaning wool or other textile materials on leaving the card or the combing machine, either in the form of a lap or sheet of fibres orin the form of a ribbon, or sliver. This machine, applied to the wools, to which it is speciallydestined, separates by beating-andshaking combined, the

so-called dog hair or dead-hair, as Wellas theshortand ,thick'fibres,-straws and other solid impurities, which invariable proportion, according to classes, are contained by the wools, even after being submitted to the usual processes of'cleaningand preparation.

Spanish Wools, especially the middling fine qualities, contain an important quantity of dog hair which considerably depreciates the industrial value of thistextile matter, chiefly due to theimpossibi-lity ofbeing able todye by any means as yet known, the defective fibresg Besides which, from whatever origin theymaybe, wools always contain a certain proportion of thick and short fibres, likewise defective, whose length varies between one andthreecentimetres, which it has also not been able to eliminate until now, in sufficient proportion, even by means of the :most improved combers, which are the only machines with which it is possible to separate these fibres, although in an insignificant quantity.

i The presence of short and thick fibres in the rovings obtained with the preparation spinning of the wool, becausewhen passing through the organs of the spinning machines they occasion frequent breaking offlthe.

thread, .which represents an important shrinkage in production anda conslderable waste of raw material. On theotherhand-,.

these shortelengthenedpfibrespossess a rigidity. which is observable inthe textures, specially in cloths, which the said fibres,

cut by the cloth-shearing machine, give them a -certainlroughness to the touch, whichis;

' The machine of my invention essentially comprises a succession ofhorizontal rulers longitudinally grooved, supported by arms; having a rapid oscillatory motion, and intercalated between couples of rollers whichcarry the fibres submitted to treatment.

The fibres, when combed or carded and disposed either in the form of lap orof sliver which are developedffrom a usual creel, or from an adequate support, pass bya guide of the machine which juxtaposes them in order to form one or more laps, andin this form the fibres are carried bythe guiding rollersof the machine, passing alternately through the grooves of theoscillating rulers, which with their rapid motion, beat on both sides and intensively shake lthelap of fibres separating byinertia, due tothei-r greater density, the defective fibres and solid impurities which were not elilninatedvby the combingor cardin". i

In the accompanying dravvings is shown a form of execution of the machine of. this in-j vention. A. y.

Figures 1 and Qshow an elevation and paringmachine, mounted with its corresponding feeding apparatus and auxiliary; engine for: the finalcomplementary processes. In sands-is showmon a'larger scale,

zillion and pl n iew respe tivel tee shaft lfi laterally mounted lengthwise to the 1 part of the machine which comprises the 'just unit or group of shaker rulers and guide rollers corresponding to the entry of the machine.

Fig. 5 shows'on a still larger scale, the

mechanism which actions the shaker rulers,

seen in vertical section through line of Figure 6.

Fig. 6 1s a vertical section of this mechanism, through line VI-VI of Figure 5.

"Fig.1? is a vertical section through line VII-VII of Figure 6, and finally Figure 8, a variation of this same, in which the shaker comprises a sin le ruler mounted on simple arms. i

The machine shown comprises, as an example, a framework 1 which carries, suitably distributed, a series of framework supports 2 which support the shaking mechanisms.

Mounted upon bearings 3 leaning alternately on the upper part of the frames'2 and on the bases of the foundation 1 of the framework, the machine comprises several pairs of guide rollers 4 whichturn at the same speed, driven simultaneously by means of a transmission chain'5 coupled'to wheels 6 fixed on to the axles of the lower rollers'which act as motors to each couple and to another wheel 7 fixed to a driving shaft 8 transverse to the machine. Each of the supports 2 supports, upon the sides thereof by means of bearings 10, 18, two transverse axles 9. These axles 9 driven by means of a mechanism described later, have a rapid oscillatory motion which is trans- 'mitted to two horizontal rulers 11 slotted longitudinally, fixed on to the ends of arms 12 V mounted on the said axles 9. By providing.

the slots and passing the fibre therethrough.

the fibre rulers will be so related that when movement is imparted to the rulers, the fibre, will be effectually shaken.

These axles 9 are oscillated by a driving machine and'provided with pulleys 17. These pulleys 17 are coupled by means; of semicrossed straps or' belts with thepulleys 15 each of said pulleys being fixed. to a crank shaft 14 (Figs. 5 and 6) which gyrates'between the branches of a fork 13 fixed to the end ofeach axle 9, the crank shafts 14 hearing onthe. same bearing supports lOwhich support the said axles 9. v

, The oscillating arms 12 which support the rulers, may be arranged fsingly' (Fig. 8) each axle 9 moving a single ruler or double (Fig. 7)

arranged like a balance-beam with a ruler ateach'end. 1

At the endcorresponding to the entry. of the machine and supported by meansof supq 'p'orts '19 fixed to the frame of-thefsame, a

guide is placed formed by a horizontal ruler 20 placed transversely with a series of'holes This guide serves to close to one another. juxtapo'se-in an orderly 'way the slivers, passing them through the said holesfatthe outlet of the creel in order that they may reach the first couple of conducting rollers 4: of the machine in the shape of one or more la s.

The entire installation set as an example of the cleaning machine which is the object of the invention, with its auxiliary feeding apparatus and complementary stretching ma- ;chine, (Figs.1 and 2) comprises a cree1'21 of the already known type, provided with four superimposed rows of pairs of rollers which develop by friction the slivers of the bobbins 22 arranged in horizontal series and leaning on the said pairs of -rollers,with a tangential speed equal to that of the guiding rollers 4c of the machine. The slivers suitably arranged by the exit guide of the creel, pass through guide 20 which juxtaposes them, forming the laps and enter into the machine already described, composed of three groups of three units each group. Between the inter mediate group and the first and third groups,

. and fixed on to the framework of the machine,

laps or. sheets of fibres instead of bobbined slivers, in which case the creel is substituted by a suitable support to develop the rolls of lap, and the perforated guide ruler 20 placed at the entry of the machine, is substituted by another which has two grooves like those of the oscillatingshaking rulers.

I claim: 1 I

1. A machine to soften carded and combed textile fibres and to separate from them the defective tfibre's and impurities, having in combination a series of rulers to impart shaking movement to the fibres, said rulers being supported by arms, means for rapidly oscillating said arms, and a series of guiding and feeding rollers for presenting said fibres to the action of the rulers which beat and shake them repeatedly. y

r 2. A machine tosoften carded and combed textile fibres and to separate from them the defectivefibres and impurities, having in combination a series of arms, means for rapidly oscillating said arms, rulers mounted on said arms, each one of said rulers being provided witha slot through which the fibres pass, said rulers serving to shake the fibre,

and a series of rollers which guideand feed the fibres'through the grooves of the rulers to be thrashedand'shaken, and thus obtain the separation of the defective fibres and impurities. a

3. A machine to soften carded or combed textile fibres and to separate the defective fibres and impurities, having in combination a series of shaking rulers mounted on arms, 7

means for rapidly oscillating said arms in order to beat the fibres repeatedly, each one of said rulers being provided With a groove through which pass the fibres to be shaken by the motion of the ruler, guiding and feeding rollers which cause the fibres to pass through the grooves of the thrashing rulers, and means to invert the'position of the fibres after having passed through a certain number of shaking rulers in such a Way that the upper face of the lap or sliver remains at the lower side and thus the impurities accumulated on this side are more easily dislodged,

4. A machine to soften carded or combed textile fibres and to separate the defective fibres and impurities, which comprises a stand which supports rolls of fibres previous ly carded or combed, a guide which carries these fibres to the shaking units, a series of shaking units, each of which is formed by rulers mounted at the end of rapidly oscillating arms and provided with which are made to pass the fibres in the shape of a lap, said fibres being shaken by the rulers, combined with couples of guide rollers slots through which determine the advance of the lap of fibres and oblige it to pass through the shaking rulers, means to invert the position of the lap of fibres in such a Way that the face which was above remains below, another series of shaking units and a Gill intersecting or other auxiliary apparatus which collects the fibres already cleaned, submits them to a combing and stretching, finally rolling them into bobbins, in order to submit them later to the customary spinning processes.

In testimony whereof I have signed my name to this specification. I

FERMIN 'ROCAMORA.
