Specification of Letters Patent.

Patented June 20, 1911 Application filed April 16, 1908. Serial No. 427,489.

To all it may concern:

Be it known that I, ROBERT J. HILL, a citizen of the United States, residing in Camden, New Jersey, have invented cerscrap gunny bagging flax orsimilar fibers but it will be undersitooddhat other fibers.

may be treated on the machine made in accordance with my invention.

The object of my invention is to'provide a machine which will rapidly and economically condense such material as jute, scrap,

gunny bagging, flax and similar fibers.

The invention 15 particularly adapted for,

condensing fibers from jute coverings used on cotton bales, so that this jute coverin can be used over and over again, but it wi be understood that my invention can be used for other purposes as well.

The fabric of cotton bale coverings is formed from very coarse fibers and the jute, if properly treated, can be used ov and over again by separatin the fibers and passing them through car ing machines and condensers, and weaving the coverin find that b the use of my improve machine the fi er is not destroyed to any a reciable extent and can be used repeated or the purpose for which it is intended: viz., for the covering of cotton bales.

.In the accompanying drawings :Figure 1, is a side view showin an im roved condenser for carding mac ines- *ig. 2, is a vertical sectional view on the line 22, Fi 1, the plates J W and W having been le i of? for clearness; Fig. 3, is a plan view ofcertain of the parts shown in Fig.2; Fig. 4, is a. plan view showing the cansand the mechan sm connected therewith;' Fi 5, is an enlarged sectional plan view on t e line 55; Fig. 6, is an enlar ed vertical sectional view on the line 66, ig. 2; Fi 7, is a erspective view of the trough; an Fig. 8, 1s a perspective view of the guard.

A is .t chine, which supports the condensing apparatus.

e rear-portion of a carding ma-- a is the main cylinder of the carding enme. g B, B are the dofiing rolls which, in the present instance, are mounted on shafts B, B and the rolls are narrow and sta gcred as shown in Fig. 2, so that the cylin ers of the lower shaft B alternate with the cylinders of the upper shaft B: extending from one edge of the main carding cylinder to the other. In the present instance there are six distinct dofiing rolls taking off six distinct slivers from the main cylinder. The lower rolls slightly overlap the upper rolls so as to remove all the fibers from the cylinders, and the end rolls are wider than those at the center so that each roll will remove about the same amount of material.

The shafts B, B are mounted on brackets b, 5 res ectively. The brackets are secured to the rame A and on one end of each shaft is a gear wheel I) and each of these gear wheels meshes with a pinion c on a driven shaft C having a belt wheel 0 around which passes a driving belt for the condensin end of the machine, so that both doflin ro s turn in the direction of the arrow,d l *ig. 6, and preferably at the same s cc Extendin in front of the dofiiu rolls B are the com shafts D, D, mounte in bearings in the frame A, and on each of these sha'fts is a series of combs d consisting of arms d and the comb proper d", which extends the full width of the dofiing roll,-and these combs are given a limited vibrating motion so as to comb the fibers from the dotting rolls to produce the slubbing. The ordinary mechanism may be used to give the necessary vibration to 't e combs.

Directly undereach comb and in front of each doiling roll is a trough E having a base portion 6 and a side flange e, as clearly shown in Fig. 7, and the trough has a downwardly extending projection e by which it is attached to the cross member A of the frame by a bolt. The bolt passes throu h an opening in the trough and through a 5 0t in theframe so that when it is desired to remove any one of the troughs the bolt can be slackened and the trough lifted out of its lace. It will be noticed that each trou h as an extension e Fig. 7, forming a etit) tier-tor for preventing the air currents carrying the stabbing over the walls of the trough. lly means of this delleetor the slubbing is directed in a straight. line to the twisting head without liability of knottin Set-tired to the frame A is a transverse stop plate I Fig. 8, which has an extension perforated for the pas age of the bolt by whit-h it is seemed to the frameA', and this stop plate extends between the troughs a shown elearlv in Fig. 2, so as to prevent the slubbing from one trough eoming in eontaet and mixing with the slubbing in the other troughs. the troughs are spaced apart sufliriently to allow for the introdnet'ion of the twisting head (i and the. roll homings l. whieh a're located at one side of each trough, as clearly shown in Fig.

v'lhe twisting head is shown in Fig. 5, and eonsistsot' a head (i having a tapered opening r with a bell mouth to reeeire the slut)- hing; the small end of the opening is oral or otherwise out of the round. ()n this twisting head is a pulley y over whieh passes the driving band y from a pulley g" on a shaft ti-'; the twisting head being mounted on a suitable brarket; (i' mounted on the frame A'iol" the tnaehine to which the arm l\' is st-eured. lhe large end of the tapered openii-ig g) being next to the trough the shtblnng freely enters the opening aml as it moves forward is eontraeted by the walls of the opening and, owing to t ie it'- regular shape of the small end of the opening, it. is given a alight twist as it, passes through the twisting head. in dealing with a tiber sueh as jute it is not necessary to give the slubbing very nun-h twist, simply enough to keep it together sothat it ran be worked.

The upper shaft- (l is mounted on a brneket A supported on the frame and the lowershal't (i is mounted on a braeket secured to the frame A. amt these shafts ean he driren in any suitable manner. At; ne end of the shaft ti is a driving pulley 1* around which passes a belt leading to a driven shaft on the earding niaehihe and on the opposite-end of the shaft (i iS a belt pulle v 5 around whieh passes a belt y" to a pulley y Qon the shaft ti.

Adjoining eaeh twisting head (i is a vertieal pair of rolls i mounted in the housings I. and these rolls are driven from the shall i on 'lllt'lt is mounted a beveled gear wheel a" meshing with a beveled wheel i on the spindle of one of the rolls amt the two rolls are geared together by pinions r so that both rolls turn in unison and draw the slubhuig through the twi ting head ti.

lhe .-lnbbing turns around one of these rolls and is led between guides on a bar I" and over a lran-versetv arranged roller m on a. frame ;\l \ihidi is supported by the main frame ol' th nelehine and from this r ll the dubbing pas es into the rains N deseribed hereafter. On the end of each shaft, I is a gear whee I" which meshes with an intermediate wheel I on a stud i. This intermediate wheel meshes with a gear wheel 5 so that the vertical rolls are driven from the shafts 13'. ll. It will be understood that the driving meehanism for the various shafts may he moditied without departing from the essential featuresof my invention.

.\s remarked above, the stabbing passes from between the vertical rolls to the drum in earried by liraekets or frames M secured to the main frame A, and the spindles m of this drum are mounted in hearings on the braekets M and on one spindle is a belt pnl'le v at around which passes a belt m" to a pulley v" on one end of the shaft I, although it will he understood that the drum may be driven from another point, if desired. llest ing upon the drum in is a roller n haringjrnnnions 1: adapted to vertical slots In in the hraekets M. lhis roller is a pressure roller for holding the slubbii'ig onto the drum at so that the drum will direet the slubbing from the condensing portion of the maehine.

Mounted on a )latform bi preferably enretl to the lloor in the position indicated in Fig. l. are disks .5 upon whieh the (ans N are mounted. ()n the under side of each disk is a gear wheel .s', indieated clearly in dotted lines in Fig. 4. and meshing with the gear wheels arm. intermediate pinions 8 lfiaeh intermediate pinion meshes with the two wheels on eaeh side of it. Atone end of the platform 5 is a vertical shaft t on \\'lllt'lt is a gear wheel I" which meshes with the tirst gear wheel a, so thatthe several disks .sare driven from one )Ullll and turn in uni on. ()n the upper end of the shaft. t i a'beveled gear-1' meshing with a beveled gear 1'" on a shaft 'l" on whit-h is a sprocket wheel 21 around whieh passes a chain I to a sproeket wheel in on the shaft or.

in making the several dotting rolls, I coir strut-t the two outside rolls wider than the renter rolls. as mentioned above, as the stock is not fed the full width of the-main eyliuder and eonsetptently the greater body of the sleek is at the renter of the main eylinder, but by making the end rolls wider as shown in the drawings, lilt'll dol'l'er removes about. the same amount of stoel(,1naking the several slnbbings equal.

in order to prevent the liber wrapping around the drawing rolls. I provide serapers I whieh are supported by the hangers and rest against the rolls. and any fiber which may adhere to the rolls is seraped otf, thus preventing the earrying ol' tiber around the roll llung from a eross bar I! mounted in si|it able supports and extendingla-tween the doil" ing rolls of the lower series are detletting plates \V. Fig. I), whieh prevent the enrto the otheris a deflector 7' arranged at an gether in the drawin action as it angle so as to prevent any fibers dropping from the upper set of dofl'ers onto the lower set. These deflectors can be made of any material and arranged in any way desired.

I preferably mount in front of the main cylinder between each of the upper dotting rolls, a guard J of sheet metal attached at its upper end to thecover X of the carding machine, and extending down in close proximit to the face of the main cylinder.

Directly under the upper row of doiier. and close to the main cylinder is a fly roll J for directing any loose material which drops from the upper dofling rolls back to the main cylinder, and it also lays the fibers on the main cylinder which are not taken up by the upper doflers. There is another fly roll J 2 under the lower doflin rolls so as to direct any loose material which falls from the lower dofl'er back to the main cylinder. These fly rolls can be driven, as indicated in Fig. 6, from the dofl'er shafts B and B by providing the dofl'er shaft and the shaft of the rolls with pulleys around which pass driving belts.

The operation of the machine is as follows :-The fiber is removed from the main cylinder of the carding machine by the dotting rolls and then combed from the d05- ing rolls by vibrating combs, forming the slubbing which passes into the trough, then throu h the twisting head; the head 'vin it suf cient twist so that it may be he d tosses between the vertical ro Is. The slob ing then passes from the vertical rolls onto the drum m and into the cans and as the cans slowly rotate the slubbin is coiled within the cans. As each can is fified it is removed and another can substituted for it. After the slabhing is removed from this machine it is formed into a yarn of the proper size.
