4 Claims.

My invention relates to a cloth guiding device.

A primary object of the invention is to provide a cloth guiding apparatus or device for use with cloth finishing machines, such as brushes, shears, winding machines and the like, the device serving to prevent lateral deviations in cloth travel while simultaneously spreading the cloth transversely and preventing the same from wrinkling during its advancement.

A further object is to provide a cloth guiding device having a novel and simplified construction, and a new mode of operation.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this application, and in which like numerals are employed to designate like parts throughout the same,

Figure 7 is an enlarged fragmentary side elevation of one guide roller and holder.

In the drawings, where for the purpose of illustration is shown a preferred embodiment of the invention, attention is directed first to Figure l which illustrates a cloth winding machine having embodied therein my cloth guiding device It. In the machine shown in Figure 1, cloth I l is unwound from a roll 12 and rewound upon a roll l3. A weight M provides friction for the roll I2, and one or both of winding cylinders l5 which support the roll 5 3, is positively operated for rotating the roll it. The cloth I I during its movement in the direction of the arrows engages a plurality of guide rolls It, arranged so that the cloth passes horizontally through the guide device ID, as shown in Figure 1. g

The guide device l0 comprises a stationary horizontal transverse mounting bar [1, long enough to extend entirely across the cloth I l and somewhat beyond the longitudinal edges thereof. Near its opposite ends, the bar I! has adapters or blocks l8 rigidly secured thereto by any suit able means. The blocks is engage the corresponding vertical sides of fixed posts or uprights l9, and are rigidly secured thereto by bolts 26 or the like. The posts [9 are arranged outwardly of the longitudinal edges of the cloth H and extend above the horizontal run of the cloth as shown in Figure 1, for supporting the bar H in vertically spaced relation to the cloth.

Trunnion blocks or bearings 21 are rigidly secured to the mounting bar l1 and spaced inwardly 0f the opposite longitudinal edges of the cloth II for equal distances, as shown. Guide roller brackets or holders 22 are arranged adjacent to the bottoms of the trunnion blocks 2| and pivotally secured thereto for free horizontal swinging movement by screws 23 or the like, The brackets 22 are bodily mounted upon the trunnion blocks 2| by means of the screws 23.

The brackets 22 are horizontally elongated, as shown, and include horizontal tops 24 which underlie the stationery mounting bar ii. The pivot screws 23 engage the brackets 22 near their inner ends 25, Figure 4, and the bracket ends 25 are spaced inwardly of the longitudinal edges of the cloth H. The brackets 22 further comprise outer depending ends 26, integral therewith and spaced slightly outwardly of the longitudinal edges of the cloth H. The lower ends of the bracket ends 26 are arranged substantially at the elevation of the cloth I l, Figures 4 and 7, and the inner and outer bracket ends 25 and 26 are arranged in spaced opposed relation as shown. Spiked cylindrical guide rollers 21' are carried by the brackets 22 and disposed horizontally beneath the bracket tops 24 and between the ends 25 and 26. The rollers 21 have their ends freely journalled upon screws 28 and 29, secured within openings formed in the bracket ends 25 and 26. The guide rollers 21 extend longitudinally of the brackets 22 for the major portion of the lengths of the latter, and the rollers are provided at their outer ends with integral undercut extensions 30 forming annular shoulders 3 i. The rollers 21 are also preferably provided at their inner ends with undercut extensions 32, integral therewith and slidably contacting the adjacent bracket ends 25. The radial spikes or pins of the guide rollers 27 project below the bottoms of the bracket ends 25 and 26, for penetrating engagement with the cloth ll.

Flat horizontal blades or keepers 33 extend beneath the guide rollers 27 throughout substantially their entire lengths, and the outer ends of the blades 33 are rigidly secured to the bottoms of the bracket ends 26 by screws 34. The opposite ends of the blades 33 are free from connection with the brackets 22 so as to provide narrow passages beneath the guide roller 21 for the marginal portions of the cloth ll, Figure 4. The blades 33 are preferably somewhat resilient, although they are relatively stiff, and serve to hold the cloth I I in positive engagement with the spiked guide rolls.

inwardly directed. tongues or plates 35 are interposed between the bracket ends 25 and blades 33 and have openings receiving the screws 36, which rigidly secure the tongues 35 in place. Inwardly of the bracket ends 26, the tongues 35 are upwardly inclined slightly as at 35, Figure 7, and the inner inclined ends of the tongues 35 engage the shoulders 3i of the guide rollers and prevent end play of the latter. lhe inclined tongues also form with the horizontal blades 33 recesses or grooves 37 into which the adjacent longitudinal edges of the cloth ii may travel when the cloth tends to deviate or wander later-- ally during the winding operation. The brackets 22 and guide rollers Eli are generally parallel to the fixed mounting bar it, as shown, but are adapted to adjust themselves angularly with respect to the bar 5?, as will be further described hereinai'ter.

Horizontal arms 33 are rigidly secured to corresponding sides of the brackets 22 near their inner ends, and these arms iii are perpendicular to the brackets and guide rollers and extend generally longitudinally of the cloth ll. lhe arms 38 are of equal length, as shown, and freely swingable horizontally with the brackets 22 guide rollers 27. The arms 33 are pivotally connected near their ends remote from the brackets to the bottoms of bearing blocks lit, by means of screws 4E. The bearing blocks 3% have openings t! formed therein for receiving a horizontal transverse connecting or tie rod Q2. The tops of the blocks 38 are provided with slots 53 leading into the openings ll, and clamp screws 4d serve to adjustably rigidly secure the bearing blocks 39 to the tie rod as shown. The tie rod 22 is generally parallel to the fixed bar if in all adjusted positions, but is bodily shiftable a hori zontal plane with the arms 38 during the operation of the guide device.

In use, the bearing blocks 39 are adjusted longitudinally on the tie rod l2 until the arms 38 converge rearwardly slightly, as shown in Figure 2.

The brackets .52 and the guide rollers 27; are now arranged at slight equal angles with respect to the transverse bar ii and have their outer portions extending rearwardly beyond the bar Ill. The rollers 2? are therefore rearwardly inclined toward their outer ends with respect to the longitudinal of the cloth l l.

The cloth l i is fed longitudinally between the guide rollers 2i and blades 23 during the winding operation, and as the cloth moves in the direction of the arrows, the spiked guide rollers are rotated by the cloth. The angularly disposed guide rollers tension the cloth transversely and maintain it free of wrinkles as they guide the cloth in a straight line and minimize any tendency for the cloth to deviate laterally during the winding.

When the cloth does deviate laterally in one direction, as shown in Figure 3, my guide device functions automatically to correct lateral deviation and return the cloth to the proper straight line. travel shown in Figure 2. With the cloth deviating laterally, in the direction of the top of Figure 3, the longtiudinal edge of the cloth ll toward the direction of deviation enters the groove 31 of the adjacent guide roller bracket 22. The engagement of the edge of the cloth in this groove 31 swings the adjacent bracket 22, at the top of Figures 2 and 3, forwardly upon its pivot 23 and this bracket and its guide roller 21 are shifted to the forward angular position, with the outer end of the bracket extending upon the forward side of the bar H. The arm 38 near the top of Figure 3, now moves rod 62 toward the bottom of Figure 3, and the other bracket 22 is swung rearwardly from the normal rear position to a further rear position with repsect to the bar i'l. When the two rollers 21 are thus angularly adjusted, as the cloth is pulled forwardly, it will be shifted laterally from the deviated position toward the bottom of Figure 3 and returned to the normal transverse central position. The action of the cloth returning to the normal position, causes the rollers 27 to return to the normal position, Figure 2. Should the cloth deviate laterally in an opposite direction, toward the bottom of Figure 3 of the drawings, then the bracket 22 at the bottom of Figure 2 would swing forwardly so that its outer end would be arranged upon the forward side of the bar ll, and the bracket 22 at the top of Figure 2 would be swung rearwardly so that its outer end would be moved further from the bar ii. The action of the angu larly adjusted rollers it? carried by the brackets 22 would then shift the cloth laterally in an opposite direction, toward the tops of Figures 2 and 3 and the cloth would be returned to the normal position. in each case of lateral deviation of the cloth, as soon as the longitudinal edge of the cloth contacts sufficiently with the tongue 35, upon entering the groove N, the simultaneous swinging of the brackets 22 occurs and the correcting action of the cloth guide commences. The device will function automatically to maintain a true straight line travel in the cloth H, with lateral deviations so slight that they are unobjectional. The lateral deviation shown in Figure 3 is greatly exaggerated, merely for the purpose of illustrating the operation of the device, and practice substantially no lateral deviation will occur due to the control aiforded by the guiding device. As previously stated, the guiding device Eii maintains the cloth I i flat and taut transversely, so that it cannot wrinkle during the winding operation.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, and arrangement of parts may be resorted to, without departing from the spirit of the invention or scope of the subjoined claims.

Having thus described my invention I claim:
