sp cification of Lettcr s iatent. Patented Sept. 9,1919,

Application filed December- 10, 1917. l Serial No. 206,436;

To (ZZZ whom it may concern lie it known; that I, MAR IN Swanson,

citizen of the United States, and resident of Passaic, in. the county of Passaic and State of New Jersey, have invented certain new and useful Improvements in Falnric-(lnuling ea in on.

My invention relates to fabricguiding devices and more particularly to an automatic mechanism whichwill keep a strip of fabric free from wrinkles, and prevent such lateral,

movement thereof as would interfere with the rcwinding of the fabric in a neat roll or bolt.

Devices made in accordance with my invention may be used in connection with a variety of mechanisms for handling strip fabrics, the purpose of theinvcntion being to so control the fabric while it is being fed through this other mechanism, or :in relation thereto, as to exert sufficient lateral stresses thereon to remove any wrinkles in the fabric, while preventing latc'al movement of the fabric in its entirety, or aside deflection thereof, which might interfere with the rewinding of the fabric or cause the formation of wrinkles thercin. 1

Devices made in accordance with myinvention derive the power for actuating same from the fabric operated upon, thus avoiding the dil'lieulties .which rnight' be encountered if said devices were used toactually feed the fabric as thcfresult of the "direct application. of power to the devices.

I so construct devices made in accordance with my invention that they may be so. set as to become operative upon the slightest deviation of the edge of the fabric from a straight line, the regulating means beingcapable of such variance in. its operative relation to the fabric as to permit nicety in the adjustment of the mechanism to adaptit to different conditions of use.

The invention consists prhnarily in a fabric guiding device eml'ioijlyiug therein a pair of oppositely di posed, cooperating rollers, movable supports for said rollers, means adapted to engage a strip of fabric, and operative connections between said means and said supports respectively,said supports being so nmunted as to have variable pivotal movement with relation to each other, where- Deriees, of which the following-is a specifiby movement of saidsupportsin one direction willrmake said rollers operative upon the fabr c and movement thereof 1n the op posite direction will make said. rollers inop .i

erative thereupong and in such other novel features of construction and combination of parts as are hereinafter set forth and do in the claims heretonppended.

Referring to the drawmgs: Figure 1 1s a front bodying my invention;

. ig- 2 is a top view thereof with. portions broken away;

I Fig. 3 is aside elevation showing the rollers in theoperative relation;-

Fig. 4 is a sim1lar.v1ew showing the rollersin the inoperative relation; and

view of a device em 1 scribed andgmore particularly pointed outw Fig. 5 is a view showing the device inits entirety in relation to a strip of fabric Like letters lefer tolike parts throughout the several views. a i Devices made in accordance with my invention are ordinarily used in pairs, one upon each side of the machine, the construction being such thatrboth devices of a pair will.

act simultaneously but with the opposite operative effect, a condition which will more fully appear when descr1b1ng the function ings of the device.

The dcviceupon each side of the machine, I however, is a;dnphcate ofthat upon the other side, sothat only a detailed desorip-fl tion of one device is necessary. J

In the embodiment of the invention shown in the drawings,the guide device comprises a fixed bracket a adapted to bemounted. upon the; frame of a machine in connection with which the guidingdevice is tobe used.

This bracket. has abifurcated extension or upon which is pivotally mounted a frame 0 having rotatably mounted therein one roller (Z of a pair of cooperating rollers. The frame 0 1s pivotally mounted in the extension 7) by means ofbearing screws or in any other desired manner, the axis of pivotal supportinn. extending obliquely to the axis of the roller 03 and substantially parallel with the line ofmovement of the edge of the fabric.

Carried by and movable with the frame. a awbracket c having pivotally. mounted therein a yoke f carrying the other roller 9 of the pair, said roller 7 being oppositely disposed to and cooperating with, the roller (Z.

Carried by the bracket a is a rigid arm h, a link It being connected by means of suitable universal joints with said arm h and an extension f of the yoke 7". By this construe tion it will be observed, the support for the roller cl (consisting of the frame 0) and the support for the roller 9 (consisting of the yoke f) are so mounted as to have variable movement with relation to each other, while being capable of simultaneous actuation, this variable movement resulting in the automatic actuation of the rollers in a manner to either separate them to make them inoperative upon the fabric, or to bring them together to make them operative according to the direction in which the f nine 0 is tilted.

-A guide plated is positioned between the rollers (Z and g, saidrollers nomnal.lyengaging the cloth through a slot in said plate. This plate is so mounted as to have move ment with" said rollers, asby means of the studs 9 carried by the frame 0. As a matter of fact, the maximum movement of the rollore is very slight.

The opening and closing of the rollers (Zg to make them inoperative, or operative withfrelation to the fabric is accomplished by means of a member adapted to engage.

the edge of the fabric, which member 1s operatively connected with the tilting frame 0. In the embodiment of the invention shown, this member comprises a cam plate 7' carried by one of the arms is of an oscillatory shaftl mounted upon one of the arms of the bracket I). Said shaft Z is provided with a slotted crank arm m cooperating with a pin a arranged eccentrically of the axis of the tilting frame 0.

The cam member is adjustably mounted upon the crank arm is, so as to be capable of beingmoved transversely of the planeof the fabric, to permit itrto be brought into, the desired engagement with the edge of the fabric, an adjustment to accommodate the device to fabrics of different widths, of different thicknesses. This construction also fa'cilitatesthe setting of the device when assembling it in relation to the mechanism in connection with which the-deviceis used.

The roller (Z is preferably a metal roller having a knurled surface, andthe roller 9 has a surface of rubber or other yielding material.

The operation of the herein. described fabric guiding device is substantially as follows Guiding devices made in accordance with my invention are ordinarily used in pairs upon opposite sides of the machine in connection with which the devices are used. In assembling the devices in relation to this machine, the brackets a aremounted upon lVhen the frames at and the parts carried thereby are set in the manner described, the fabric is threaded across the guide plates 2' with the opposite edges thereof between the rollers (Zg of each pair, one of which rollers has a knurled surface, as shown and the other of which is provided with a rubber or other flexible surface. In threading the fabric thrmiglrthe machine, when originally installing the guiding devices thereon, this fabrlc should be drawn taut. Thereafter the cam j on each device is so set as to bear upon the edge of the fabric, the manner of mounting this cam upon the crank arm it permitting this adjustment.

hen the parts of the. device have been properly set with relation to the machine in which they are used, and to the fabric itself, power may be applied to this machine so as to draw the fabric therethrough.

So long as the fabric runs perfectly true, the edges thereof will have no operative effcct upon either cam, j, but instantly upon the fabric running out of true, or skewing slightly. the pressure from the fabric will be increased as to one of the cams j, and relieved as to the other. The increase of pres, sure above referredto will have a tendency to rock the haftl through the crank armin and pin 91, thus tilting the frame a and bracket aabout the pivots supporting said frame 0 in a manner to force that portion of the rollerd adjacent the portion thereof engaging the body of the fabric or toward the center line thereof, away from the fabric. The movement of the bracket 6 simultaneously with the frame (3 will have a tendency to move the yoke f and the roller 9 in synchronism with the roller dfbut the link it operative upon the other" end of the yoke f will restrain such yoke in a manner to limit the tiltingaction of said roller, the rocking of the yoke f about its pivots and the 'universal connections in the link It compensating for the resulting differential of movei ngsr. i

the shaft Z controlled thereby in thedirection] opposite to the movement of the shaft 1 of the other device of the pair, thus insuring a,

continued engagement of therollers of the 1 last named device,,with the fabric, with a possible increase of pressure, The operatrons of the two devlceswill be simultane g ous and consequently nstantlyasthe rollers cl and g of one device separate, the rollers oi? the other device of the paiimwillimpart lateral movement to thefabric, thus permit-p ting the camy of the device in which the.

rollers are separated to. resume its norrnal position thereby bringing the rollerscl and y upon the fabric. y y I The cams j maybe set with suflicient nicety to prevent any substantial deviation of the fabric from a straight line. thus per-' mittmg the correction instantly of any tend- 011057 of the fabric to run out of true. y

\Vhile I have referred to such a separation of the rollers (l and g of one pair as will per-,

mit the, fabric to passifreely therethrough without any tendency of the rollers to imy part lateral movement thereto, nevertheless, it must be understood that a partial sepaqtweenisaidmeans and said supports, means ration of these; rollers willhave the effect of developing a differential of the lateral stresses applied by the rollers of one device support, whereby said rollers are caused to have variable pivotal movement with rela tiongtoeach other, and connection between said supports whereby movement of said .supportsinaone directionwill make said .1 rollers ,OPGltLiZlVB upon the fabr c, and movement in the; opposite directionwill make said i. i

. rollers inoperative thereon.

2. A. fabric guiding device embodying therein ;a pair of oppositely disposed, cooperating rollers, a pivotal support for each i of saidrollers,,means wherebymovement of i one of said supports transmits movement to the other, means acting upononelof said} supports whereby movement of one end a thereof in one direction is restrained to cause said supports to have variable pivotal movement wlth relation to the other, means adapted to engage a strip of fabric and and the rollers of the other. device, which i will result in sufficient lateral movementof the fabric to cause it to runfperfectly true.

It will be observed thatithe power for actuatinga device made in accordance with n 1y invention, is derived solely from the fab-. 1'10 and that the device n its funct onings is purely mechanical throughout.

The tilting of. he gulde i. when the rollers are separated will have a tendency amuse;

the fabric to move laterallyso that aiguide mechanism made in accordance with .my i11 vcution might be used with narrow stocln:

utilizing the guide xplate i for imparting lateral movement thereto, in lieuof the use of devices in pairs, as, herein described.

It is not my intention to limit the invention to the precise detailsofconstruction shown in the accompanying drawings, it being apparent that such may be varied with: out departing from the spirit and. scope of the invention.
