To all whom 2'25 may concern;

Be it known that. I, DANIEL. YOUNG, a citizen of. the United States, residing. in Brooklyn, in. the county of Kings and State of New York, have invented. certain new and useful Improvements in Apparatus for Treating and Forming Weighted. or Loaded. Sheet Fabrics, of which the following. is a specification.

The objects of my invention or inventions herein disclosed are to provide a. new and improved apparatus for treating sheet-fabrics, of'any and all forms,.in wliichuin the course. of such treatment the fabricesheet is unroilediand' rerolled, and in its passage from feed. to receiving or take-up. roll is supplied with any required impregnating, loading,

weighting or surfacing material, the proper amount of such: material supplied to the fabric-sheet,..of which,.it is necessary to determine from time to. time by. weighing the. same, until, the required grade of: the finished material has been reached by. the depositionv or, impregnation. of the fabric with the required quantity of theimpregnating. or. loading material; and may be applied to sheets of woven or knitted fabrics,

leather,. etc..; paper of all forms including.

sensitized photographic papers, etc..; but. as

shown and described. herein my. said improved1 apparatus are those especially adapted for the: water-proofing or. as it 1s commonly known inthe' art, rubberlzmg of I woven sheet-fabrics.

My said improved apparatus is fully shown, described and claimed in the fol lowingv specification, of which the accom panying drawingforms a. part, wherein' similar. letters, or. numerals of referencedesignate like or equivalent parts wherever found'throughout the several news, and 111 which:

Figure 1 is a front end. view. in elevation.

of improved combined weighing and roll-shifting, apparatus, for carrying my:

saidv method. into effect, in position ready to be operated;

Fig. 2 is a side view of such apparatus looking toward-the left of;Fig,.1inthe direction of the arrow,.in position upon the roll-supporting mechanisms showing the roll' of fabric in position thereon.

Referring to. the drawing The reference letter A,.. designates the front. end of a fabric-sheet waterproofing or. rubberizing. machine of: an old andwell known. form, showing my improved combined roll-shifting and. roll-weighing apparatus B attached thereto;v C designates the steam-coil fabric-sheet supporting: and. drying. bed; D the combined trolley-carriage andweighing scale of B; E. the. combined lifting and roll-swinging, shift frame;- and F, a roll of the sheet-fabric about. to. be. treated, in, position upon the. supportingshaft. I

In the treating or rubberizing machine, the reference numeral 11 designates the knife-roll shaft, supporting and: rotating the knife-roll 11, such shaft 11 being rotated tothe right as shown by the arrow. by the pulley 12, connected. with a drivingpulley. l3v by a belt 12. Such knife-roll 11 is sofcall'ed for the reason that just above it is located a spreading-knife, which extends longitudinally thereof with just space enough between it and the peripheral. sur-' face of the roll, to permit the. passage of the fabric-sheet H (shown in dotted lines) and the required quantity of rubber or other impregnating material superposed thereon, the surplusbeing held back by such knife, whichwhile not shown, is adjusted to the proper height by the screw-shafts I operated by the hand wheels I, which shafts are attached to the knife at either end; K designates the upper or feed-rollmechanism carrying the roll F, of sheet-fabric H, about to be treated, from which roll the fabric H passes up over the knife-roll 11, just before it reaches the knife, being fed with a sufficient quantity of the rubberv Or other treating material or fluid, usually delivered automatically from any suitable automatic feeding-receptacle, the surplus being held back by the knife; and from the knife roll the top-ply of fabric H, passes over the drying bed C, usually of the steamcoil form shown, at the extreme end of which it passes downward over an idler-roll (not shown), and the bottom-ply H, returns to the front, and is Wound up on the take-uproll L, all as clearly indicated in Fig. 2; the lengthzof the hot drying steam-coil bed being such that by the time the treated fabric has passed over it to the end-roll (not shown), the rubber, etc., will have been thoroughly dried. The feed-roll K, and take-up-roll L, are of identical construction, being at one period one, and then the other, and are each comprised of a rectangular roll-shaft, 20, upon which is mounted a roll-sleeve 21, usually for the sake of light ness of wood, having a squarecentral longitudinal bore to receive the shaft 20 so the shaft and sleeve will rotate in unison.

Axially mounted on, or connected with the shafts 20, at eitherend so as to rotate in unison therewith are wheels, which according to the varied positions of the shafts, in the feeding or take-up positions as hereinafter described, serve either as drive or brake-wheels, according to the exigencies of their particular position at the moment. The roll shafts are supported in position upon the main-frame A of the machine upon supporting-brackets 15 and 15 respectively, formed integral with the securing base-plate let, secured by bolts 31 to the front end side-pieces or flanges 80 of the mainframe A; which supporting-brackets are provided at their outer ends with suitable journal-boxes P in which such shafts 20 are revolubly supported. And in the forms of fabric-treating apparatus hitherto used, upon which my apparatus is an improvement, the wheels 28, 28 and 29, 29 are secured to the outer ends of the shafts 20, which extend through such journalbones P, which are provided on the upper sides or faces with slots (not shown), per mitting of such shafts, wheels, etc., being lifted out of such journal-boxes. And hit-herto in the operation of the machine this is done by two men each taking hold of an end of the shaft and lifting the same clear, the lower take-up shaft L, carrying the finished roll of fabric F, (Fig. 3), after being taken out and placed upon a scale so as to determine the increase in weight of the fabric, being then replaced in the upper and feedroll journal-boxes of the brackets 15, while the empty feed-roll shaft of K, removed from such upper boxes is then placed in position in the like journal-boxes of the lower-brackets 15, to act as a take-up or finish roll. And in this shift, by the machines and processes heretofore used, for the reason that there may be some difierences as to the thickness or quantity of the treating material fed to the two side edges of the fabric being treated, in order that such discrepancies of feeding may be overcome in order to make a smooth and perfect coating or impregnation, etc., of the fabric (especially, when as in the higher grades of rubberized fabric). it is necessary to run the fabric a number of times through the ma- --chine, sometimes as many as five or six, when the take-up roll is shifted into posimethod herein disclosed, described, and

claimed, by the form ofapparatus for carrying the same into effect, also of my 1nvention set forth herein, the brake and drive-wheels of the roll-shafts remain permanently in position in their journals, and

only the center removable fabric-holding wooden slip-sleeves 21, and shafts 20, constitutin the fabric-roll supporting por tions or such shafts, are removed, thus greatly lessening the weight necessary to be shifted; and by my improved combined roll-shifting and weighing apparatus, I obviate the necessity of removing the roll to be weighed from the vicinity of the machine to a separate scale or weighing mechanism.

in my improved form of apparatus the combined drive and brakewheels 28, 28, and 29, 29, instead of being secured upon the shafts 20 are secured in'any desired manner usually by means of cotter pins or set screws 22 upon short studshafts 17, 17, and 19, 19. The wheels 28 and 29 being rigidly secured upon the outer ends of the studshafts 17 and 19, formed'integral with the stud-shaft socket-heads 22, having at their inner ends a square or rectangular orifice to receive the like shaped securing ends 22 of the roll-shafts 20, upon which are formed the cylindrical portions .23 for the securing thereto (as hereinafter described), of the lifting releasable twin-hooks 52 secured to the ends of the two depending portions 51 and 51, comprising the lift-chains N. The stud-s1ipshafts 11 and 19 are each formed integral with a boss 27, against the outer face of which the pulleys 28 and 29 abut, which boss is provided with the journal inner portion or stud shaft sleeve P which passes through the journal-box in its particular bracket 15 or 15 and is provided at the end with the central axial sliphollow 26, in which is slidingly held by means of the securing-pin 26 passing through the slot 25, the rear cylindrical slip extension of the reciprocating studshaft socket head 23; a coil-spring 24: being interposed between the end of the main portion of the stud-shaft and the socket head 23, normally forcing such socket-head 23 out to the limit of the play of the securing-pin 26 in the slot 25, as clearly indicated in Fig. 8; and after insertion in place in the bracket-journal, the stud-shaft sleeve or journal inner portion P is secured in fabricstrip becomes place by a collar 27 secured thereto by a set-screw, or in any other desired manner.

Secured above the brackets 15 and 15 usually and preferably parallel with the axes of rotation of the shafts 20, is an overhead trolley-rail 33 usually of the I-beam form shown, suitably supported in position, usually by being secured to the ceiling upon which travels the carriage-yoke 3%, having the supporting traction-wheels 35, which yoke supports the main-bar 36 of the combined supporting trolley-carriage and weigh ing-scale D. Pivoted to a downward extension of the main-bar 35 by a pivot 36, is the vibrating scale-lever 37, the outer free end of which vibrates up and down between the two lock-cam supporting yoke-pieces 28 formed integral with the scale-lever 37, carrying at the lower end the lock-cam pivotshaft 41, vibrated by the lock-cam lever 39, and carrying the lock-cam 39 shown in the vertical scale releasing. and unlocking position, in Figs. 1 and 2.

Formed integral with or rigidly secured to the scale-lever 37 at its outer free end adjacent to the lockcam 39, is the scale actuating-rod 40, connected with the scaleplunger or vertically reciprocating-shaft 41 by a pivot-bolt 42; the scale-mechanism and dial being indicated'by 43. Pivotally supported by the scale-lever 37 adjacent to the center, is the supporting scale-hook as, carrying the roll swing-lift supportingchains 45 and 45, the outer ends of which are hooked or otherwise firmly secured to the end journal-box pieces 46 and 46 of the lift swing-frame E, formed integral with the cross bar 47 and central journal-box piece 47', journaled-in which is the driveshaft 4:8, rotated through a sprocketwheel 4c9,by an endless hand-chain 4:9, or by a power-pulley 50, driven by a belt. Also revolubly supported in lower journal-boxes formed in such pieces 4E6, i6, and 6L7, is the lift-chain shaft 55, upon the ends of which are secured the lift-chain gear- wheels 56 and 56, meshing with like smaller drive gear wheels 57, rigidly secured to the drive shaft 48; and secured upon the ends of the ilift-chain shaft 44:, are the liftchain sprocket-wheels 5%,actuating the roll supporting-chains N, provided at their ends 51 and 51, with the twin-hooks 52, for supporting the roll shaft 20 by being slipped over the cylindrical end portions 23 thereof.

Formed integral with the journal-box piece 4L6, of the lift-swing-shaft E is a bar 61 formed integral with a housing 60, through the center of which passes the drive-shaft 48,- which housing contains within it a two-way reversible and releasable stop-pawl drive-shaft locking-device, and mechanism actuated and shifted by the shiftlever 62, whereby, by the throwing of such lever 62 into the vertical position shown in Figs. 1 and 2, the drive-shaft 48, and con-- sequently the shaft 55 will be locked against rotation, and when shifted to the horizontal in one direction, will act as a stop-pawl against rotation in one direction, and when in the opposite direction, reversibly, whereby as the chain 49 is operated such ratchet and pawl-mechanism will maintain the rolls being shifted at any desired height without danger of accidental displacement.

In carrying out my improved method herein disclosed, and operating my improved apparatus therefor, I take the following steps:

A roll of the fabric F yet untreated by my improved process mounted upon the wooden axially rectangularly perforatedsleeve or mandrel 21, is slipped upon a rectangular feed-roll shaft 20, and the twinhooks 52 of the ends 51 of the chain N are thrown over the cylindrical lift portions 23, of said shaft and by manipulation of the drive chain &9, and the consequent rotation of the shafts t8 and 55, such fabric-roll and supporting-shaft are lifted into the space between the feed-roll studshafts l7 and 17; and the right hand rec tangular end 22 of 20, being thrust into the like-shaped stud-shaft socket of the reciprocating stud-shaft-head 23, the shaft is thrust back into the socket 26, against, the tension of the spring 24:, and the right hand end of such shaft 20 being brought into registry with the like socket of the stationary stud-shaft 22, it will be forced into the same by the tension of the spring 24: and maintained in such position during rotation by the tension of such spring 24; or any suitable locking device (not shown) may be added to prevent accidental slipping of the roll-shaft. When so placed in position, the end of the sheet of fabric forming the roll F is passed up from the under side of the roll, over the knife roll 11, and between the same and the knife (not shown), and over the steam-coil drying-bed C, and after passing over the end roll (not shown) is threaded back underneath the drying-bed O and secured to a like wooden slip-sleeve 21, mounted in like manner upon the finishroll or take-upshaft 20, which has been placed in position in similar stud-shafts located in the journal-boxes of the lower outer journal brackets 15. The manner of securing the end of the sheet to the takeup sleeve is immaterial and may be done by tacking, or any other desired manner; or even only by turning the take-up roll a number of times so as to wind several layers on the slip-sleeve 21. The take-up finish-roll L is rotated by either the wheel 28 or 28, usually by 28, usually by means of a belt O, (Fig. 1), driven from any suitable p0wer-supply source. The feed-roll wheels 29 and 29 are provided with suitable adjustable braking mechanisms of any suitable form by which the fabric sheet is steadied and lrept under tension in its passage through the machine.

The wheel 28 and talre-up-sha-ft 20 and sleeve 21 being put into rotation to the right in the direction of the arrow in 2, the fabric is drawn off from the feed-roll and as it passes over the knife-roll 11, the fabric at the knife-roll is suppiied by hand or by an automatic-feeding-device, (not shown), with the required quantity of the impregnating or surfacing material to be deposited in or on such fabric, the surplus being removed by the knife (not shown), located above such knife-roll hereinbefore referred to; and being thoroughly dried in its passage through the machine upon, over and along the steamcoil drying-bed G, is wound up on the takeup roll L; and l efore the last end is allowed to pass over the knife-wheel, a threadcr leadsheetof other material is attached to such end in the manner well known in the art, and such lead-sheet left in the machine to act as a leader for the insertion of the same or another sheet, and when the front end of the lead-sheet is wound three or four times around the take-up-roll, the take-up-roll is reversed in rotation and the threader leadsheet separated from the treated fabric, thus preventing the labor and time that would be taken, in threading the fabric sheet by hand through the machine upon the continuation of the operation.

The combined weighing and liftswing mechanism B carried by the trolley-carriage D, is then moved into position and the chains N having had their ends 51 secured to the empty-feed roll-shaft 20 at K by the placing of the twin-hooks 52 upon the cylindrical portions 23 of such shaft, as clearly indicated in Fig, 1, while the filled take-up and finish-roll carrying the treated fabric-roll F,

is secured in like manner to the ends 51, by.

he twin-hooks 52. The lock cam 39 is then by the movement of the lock-cam lever 39 to the horizontal-vertical and toward the right of Fig. 1, thrown into upward locking position so as to lock the scale-bar 37 against downward movement, thus rendering the scale-mechanism inoperative, whereupon, by rotation of the drive-shaft 28, the lift-shaft 55 is (after the removal of the shafts 20 from their respective stud-shafts) rotated so that the roll shafts are reversed as to vertical position; and also swung horizontally a half turn upon the pivot-hook ri, to bring about end for end reversal of the rolls, when they are again inserted in place in the studshafts by which operation the rotation of the feed-roll K will be reversed; that is if the fabric sheet H has been first fed from the under-side of the feed-roll K, as indicated in Fig. 1 this reversalwill cause it tobe fed from the top so as to bring what was the under and races-r3 untreated side of the fabric-sheet uppermost, and in position to be itself treated, in the manner hereinbefore set forth. In some cases, and when only one side of the fabric is to be treated or coated, there is of necessity no such horizontal swinging of the rolls. During this swinging operation the lock chains having the securing-hook 53 one of which is secured to the middle of the endportions 51 of the lift chain l having been hooked into the end 51 of such on either side as indicated in dotted lines at 53 of Fig. 2,

which will prevent swinging apart of the rolls during the swinging reversal; while the rolls are, upon unhooking of such chains maintained in any desired vertical position by proper manipulation of the pawl and ratchet shift-lever 62. in position, (usually when the rolls are in quarter turn position) the lever 39, is thrown down in to the vertical position shown in 1 and 2,. so as to unlock the scalelever 37, when the weight of the finish-roll, of the two-rolls and the fabric, and the swing shift-mechanism will be indicated upon the scale-dial 43; and the tare of the supporting mechanism, and the weight of the fabric and its square-yardage surface being known, this weighing between each passage through the machine, by a simple math" ematical computation, will at once determine, when the required grade of treated fabric has been reached, whereupon the finished-roll of fabric F is removed, and a new and untreated roll inserted for like treatment.

it is evident that many changes and modiiications in my improved method of fabric treatment, and also in the construction, arrangement and combination of the several elements of my improved apparatus for carrying the same into efiect, herein disclosed, may be made without departing from the scope of my invention, and I do not intend to limit myself to the exact construction of apparatus, nor to all steps, nor to the exact sequence of steps herein disclosed, shown and described.
