To all whom it may concern: a

Be it known that I, CHARLEs B. JOHNSON,

a citizen ofthe United States, residing at Paterson, in the county of Passaicand State of New J ersey, have invented certain new and useful Improvements in Machines for Treating Fabrics. of which the following is a specification. i

This invention relates to machines for ad-.

One part of my invention consists inlnovel means for effecting the advance ofthe material in its own plane; another part con sists in a novel means for controlling the relation between the material and means to operate thereon, as brushing means, par

ticularly with reference to reversingthe die. rection of traverse of the: material 1 another part consists in novel means for controlling i the relation between the material and means to operate thereon, as'singeing means, par-.

ticularly with reference to stoppingfand starting the advance of the material; another part consists in novel means for disposing of the product, as the charred lint, ofthe brushing operation. The invention further con sists in certain combinations and arrangements of parts whereby various operations necessary to reverse the machine a're all ef- .fected from a common control means.

My invention is shownherem 1n connec: tion wlth-a machine fors1nge1ng-andhrushingfabrics wherein the fabric isadvanced in its :own plane from; one end .to the other thereoffirst in one. and then in the-other direction past a singeing means and alsopast two brushing nie'ansrarranged on relatively! opposite sides of the slngeing means and so controlled that in which ever-direction the fabric is advanced" the brushingmeans first approached will be inactive and the other active. 1 q

Fig. 8 is a sectional view on line 88 of Fig.2; and 3' Figs. 9 and 10 are detail views of the feed or nip? rolls.

a is a suitable frame having atthe front bearings for a horizontal drive-shaft I) having a pulley 0 whereby it is driven. and splined to it a friction wheel dswhich may be shifted thereon by a screw 6 journaled in the frame and carrying a nut suitably engaged with the friction wheel. At right angles to shaft 6 there is journaled in the frame a shaft '9 movable in its bearings toward and from shaft Z) to bring the face plate 7L thereon into and out of driving contact with the friction wheel. The thrust of shaft 9- toward shaft 6 is accomplished through a lever 2' (Figs. 2, 4: and 5) from a cam on a shaft is jouriialeol, parallel with shaft 5, at the back of the machine. The speedof shaft 9 may be varied by adjusting tllie friction wheel with respect to the face p ate.

Parallel with shaft 9 and at opposite sides of the frame there are journaled two rolls Z which are driven in relatively opposite directions by sprocket-and-chain connectionsflfronrthe shaft 9, i. e., a sprocket m on one roll and a sprocket n on said shaft are connected by achain 0, and a sprocket 79 (Fig. 4) on the other roll and a sprocket g on a counter-shaft r are connectedby a chain 8, shaft 9 and counter-shaft 1 having intermeshing pinions t-u, respectively. The fabric extends over the rolls 1. Over each roll Z isa pressure roll 4) journaled in a bracket 'w fulcrumed' in the "frame. The brackets form a part of a toggle means whereby when one roll '0 is allowed to bear on the corresponding (continuously rotat ing) roll .Z' the other will be elevated out of r .coactingrelation to the corresponding (continuously rotating)" roll Z. Thetoggle means includes? a rocker consisting of a transverse shaft mcarrying a pair of V-.. shaped cranks/y, and links 2 connecting corresponding arms of the cranks with the:

levers. w (Fig. The rocker has also a crank or arm 2, andgwhen it is moved one Way or the other by means (to be described) connected with said arm 2 it will obviously cause one roll 1) to be elevated and the other depressed. In practice, the right hand advancing means serves to feed the fabric to, the right, at which time the roll 4) thereof. is coacting with its roll Z, the roll a: of the other advancing means being elevated and 4) holds the first in effect locked against withdrawal and pressing against its roll Z.

In accordance with the well-known principleof machines of this type the leading end of the fabric is wound on-a take-up beam, there being two such beams,- one for each end of the fabric, and there are clutches whereby the beams may be disconnectively connected with means forrotating them, so

that one may be driven to wind up the at vancing endr'of the fabric and-the other run free todeliver the fabric. The beams are each removably supported at one end- (being suitably journaled at the: other end in the frame) by a head stocklor mandrel 3 (Fig;

6) ijournaled in the frameand carrying, revoluble thereon, a driving'clutch member a and splined thereon a driven clutch memi berior fork 5 adapted to: be shifted by a bell-crank lever 6 into andout of clutching engagement with the member 4. hlember a, which is also a pulley, 1s drlvenicontlnuously from a pulley 7011 the adjoining roll Z through the medium of a belt There-V .is a stirrup rod 9 having;a{ universal-joi-nt l connection. with each bell-cranlrleyer 6 and it carries a cushion spring10'and above the spring a collar 11, the object of which will be explained later.

is pairof parallel levers, one at each' side of and sultably fulcrumed in themachlne, and-13 a bar pivot-ally connecting them and also p ivotally connected with the rocker arm' 2 andihavingits movement with the levers in each direction dim-fired by a;

springstop 14L engaging insuitable notches in the bar (Fig.1). a The levershave out-f wei dly projecting cranks 1.5 to which are pivoted collars 16 penetrated by the rods 9 and interposed betweensprings 10 and collars llithereonm hen the: system of parts 12, 13 :isshifted'to buckle one and straighten a the other toggle connection, thus depressingone roll a and elevating. the other roll} 0, the rod 9 corresponding tothe first toggle connection will be depressed and the other elevated to'respectively engage and disengage the corresponding driven clutch members 5 with respect to the (continuously rotated) clutch members l. The cushion spring 10 allows yielding should the fork 'be forced inward when opposite the lugs 4 of the driving clutch member.

There is a pair of horizontal suitably cooled guide rollers 18 arranged in the verticalicentral front to-rear. planeofthe machine,andfulcrumed on axes in this plane is a pair: of singeing devices 19, one below each roller 1-8, the Vdevices 19 have reversely projecting cranks'20 whichare connected by a link 213so that thessingeing devices may be conjointly shifted on their fulcra'into and out of operative relation to the rollers 18 which, as will be understood, afiiord a suitable backing for the fabric while being singed- The shifting? ofvthe sin geing de vices is efliectedfromthe shaft by aworm 22 thereon and an arnr23 onthe lower crank 20, the arm 23 having a roller Ql-engaging the worm (Fig. 8). Shaftlc is turned in one direction .to start and in the other direction to stop the machine, through the medium of parts j, g, h and-, by the means whereby the. system of parts including the singeingi devicescare connected "with; saidshaftIZc, when the latter isrotated to stop the machinefthe singeingdevices are shifted out of'pos-ition for singeing (where, with the fabric stationary, it would ofcourse be burned). and whenit is rotated to startthe machine they are shifted into position for singeing. r 1' it At leach endof the machine there-is a pair of: levers '25 having their upper and lowerendsiconnectedby the pairs of links 26; A parallel lever system is thus formed; Eaclrpair; of links carries two guide rollers 27, one near each end thereof Thefabric A in thepresent instance extend-s under and over the lower-and upper'right-hand guiderollers 27,1'espectively, then; under the lower guide-roller -18, thenover anidlerrollerEZS,F

thenunder the guide-roller 18; then over an i idler roller 29, and then down to the right side of-the -left-hand guide-rollersf27. The pairs of upper and lower rollers27, one'pair at the right and the other at the left, afford means to maintain separatetautstretches A of the fabric, and on shifting the parallel lever systemon itsfulcra said stretches will shift from the planes indicated by the solid lines to thosefindicated by the dottedlines inF1gn3'. This has to do with the brushing means, and a "further explanation thereof,

n'i eonnectionwvithf S means: will follow The shifting ofthe lever-system iS y nated with thereversing of the directionof advance of the fabric by the following" means 30 is a lever fulcrumedin the frame its other end connected with the lever system by the link 33. T o vary the throw of the lever system pin 31is adjusted in the. slot of lever 30.-- i

. The brushes 34 revolve on horiz ontalaxes a to which an exhaust means may be attached.

V the left-hand roll 1.

and are contained in housings 35open to-- ward the fabric. Each housingjis also provided with a delivery outlet 35 at one end,

So far as I am aware this feature is new in machines of this kind, in which-space is wasted by exhausting means being'attached radially instead of axially of the housing in the usual construction. -Each brush has a pinion 36 and the several brushes are continuously rotated through a chain 37 from a gear 38 (Figs. 1 and 4) fixedtorotate with There are four brushes, a pair (relatively-to the length of the fabric) on each side of the singeing means. The'brushes in each pair are adapted to brush the opposite faces of" the corresponding stretch A ofthe fabric, and such stretch and the plane in which "the axes of the brushes lie form edgewise an X. The two lower brushes are betweenthe stretches and the two upper brushes outward of them.

Whenthe parallel lever system is shifted one'way or the other from bar 13 it will be apparent that each planiform length or stretch A will move from one to the other of the solid and dotted line positions thereof shown in Fig. 3, so that according to the direction in which the shifting takes place it will be moved'into contact with or away from each of the corresponding brushes. By placing the pair of lower brushes between and the pair of upper brushes outward of the stretches A the shifting of the lever system in either direction brings one stretch against its brushes and the other clear of its brushes." The connections between the lever system and thebar Bare such that according to the direction in which the fabric will be advanced the brushing means that is approached by the fabric after passing the singeing means will be active and the other rendered inactive (so'as not to brush and thus abradethe fabric tono purpose) Varying the throw of the lever system by adjusting pin 31 in lever 30 changes the degree of pressure of the brushes on the fabric; thispres'sure'may'be alto;

gether eliminated by adjustingthe pin into coincidence with the fulcrum-of lever 30.

- now be apparent. Having arranged two stretch (A) shifting means corresponding to the empty beam will be active and the corresponding means appertaining to the full beam will be inactive. Shaft I) being in rotation, shaft is is turnedto move the face plate against the friction wheel and throw into action the singeing devices. From now on, until the process is completed, the two rolls Z, driving clutch members 4 and the two sets of brushes remain continuously rotated. Each time the fabric has been un-, Wound from one beam and wound up on the other the operator reverses the machine by shifting bar 13 so that the advancing means, beam and brushes that were previously active become inactive and the other corresponding parts become active, repeating the reversing process as many times as may be necessary in order to complete the singeing. I

Suitable means is employed for supplying a combustible to the singeingmeans and a cooling medium to the rollers 18, but these form no part of my invention.
