Application filed' February 5, 1915. Serial No. 6,313.

ing of paper or fabric as it is being wound upon the reel or spindles of a winding machine. In machines of this character, such, for instance, as shown in my Patent No. 952,282, March 15', 1910, there is more or less difficulty in forming rolls with even ends. This difiiculty is mainly due to the non-uniform character of the wall paper or other fabric which is being reeled. The paper, for instance, is apt to vary in thickness, and there is also more or less variation in the length of the edges of the strip,

due to uneven shrinkage or differences in the manufacture. These varlatlons 1n the length of the edges, or looseness. of one or the other edges of sides of the strip, tend to cause the paper or fabric to feed unevenly on the spindles. For instance, where one side is tight, the paper being wound on the roll tends to travel toward the side having the greatest tension, and therefore makes an uneven end on the roll which is being wound.

The objects of the present invention are to provide a governor or guide to overcome such difliculties, and which will tend to regulate the movement of the strip of fabric so as to feedthe same properly and form even rolls on the spindles:

In the accompanying drawings illustrating my invention; Figure 1 is a top view of the governor or guide as applied to a machine such as shown in my prior patent, parts being broken away for convenience in illustration; Fig. 2 is a rear elevation of the device; Fig. 3 is a sectional end view; Fig. 4 is a detail illustrating the method of operation; and Fig. 5 is a modification.

As illustrated in these drawings, 6 rep resents the frame of the reel or winding machine, which may be of any ordinary or preferred form of construction, and which is provided with a guide roller 7 for guiding the paper or fabric 8 to the spindles 9. Any suitable means may be used for driving or operating the spindles, such means forming no part of the present invention. The fabric 8 passes over the guide roller 7 and down to the spindle 9, upon which it is wound. As the roll on the spindle increases in size, the position of the portion of the strip between the guide roller and the roll gradually shifts to the left, as seen in Fig. 3. This much of the machine has been fully disclosed in my prior patent.

.My improved governor construction comprises a cross barlO having arms 11 at the ends thereof, which are pivoted concentric with the roller 7, as upon the shaft .12, which supports said roller. Two bolts 13 are connected with the bar 10 at either side of thecenter thereof, and are connected at their lower ends with a plate 14. A yoke 15 is provided with pivots 16, which engage with the bar 10 and plate 1 1, so that the yoke may swing freely in a substantially;

horizontal plane. Springs 17 are fixed in the bolts 13, and engage with the yoke 15 to steady the movement of the yoke and tend to hold it normally in central position. The yoke 15 carries a roller 18, which is roftatably supported betweenthe ends thereof,as clearly indicated in the drawings, and particularly in Figs. 3 and 4:. It will be noted that the roller 18 and connected parts being pivoted .on the shaft 12 will swing 1 under, the influence of gravity until the center of gravity is directly below the center of the shaft. The parts are preferably so proportioned that, at such time, the outer portion of the roller 18 will pro ect slightly -within the path of the fabric 8 at the .be-

ginning of the winding movement. Then as the lower portion of the fabric shifts to the left, due tothe increasing size of the roll on the spindle the roller 18 and connected parts willbe. swung by the fabric slightly to the left. In order to adjust the position of the roller 18,-I provide an adjustable weight which may be arranged in any convenient manner. bar 10 is shown as provided with a rearwardly extending screw 19, upon which a threaded weight 20 is mounted.

In some instances it may be desired to hold the roller 18 in fixed position. This may be done by means of the arrangement shown in Fig. 5, in which the bar 10 is shown as provided with an arm 21, which is connected bymeans of a screw 22 with the frame 6. A plurality of holes may be provided for the For instance the V screw, so as to adjust the position of the bar 10, and consequently of the roller 18.

When in operation, the fabric 8 passes over the roller 7 and engages with the governor roller 18, and then passes down to the winding spindles 9. The roller 18 projects slightly within the path of the fabric, and is free to turn as the fabric passes over the same. As long as the fabric is of uniform texture and both sides are of the same length, it will merely pass over the roller 18, and will be evenly wound on the spindles 9. If a portion of the fabric is loose along one side,

that is, one side is stretched relatively longer than the other, the tight or shorter side will act against the roller 18 and swing the roller and yoke on the pivots 16. As the roller 18 swings in a horizontal plane the opposite end places an additional tension on the loose side of the fabric. This additional tension on the loose side would tend to cause the fabric to move longitudinally of the spindle toward the side having increased tension, but the resultant action causes a uniform winding of the paper or fabric on the spindle.

1 have found in actual operation that this governor or guide will serve to correct the tendency toward irregular winding, and will enable the reel or winding machine to 'wind straight ended rolls even where the paper being wound is of greatly varying texture, and particularly where the paper being wound is stretched or elongated, in portions, as along one side and then the other. The operation of my improved device will be readily understood by those familiar with the art, and it is obvious that the construction and arrangement of the same may be greatly modified to adapt it to different machines or different conditions, and therefore I do not wish to be limited to the exact construction or arrangement herein shown and described, except as specified in the following claims, in which I claim:

1. The combination with a reel or winding machine having a guide roller and having a winding spindle, of a yoke pivotally mounted concentric with the guide roller, a

second yoke pivotally mounted to the ii named yoke and swinging in a plane at right angles to the first-named yoke, a roller mounted in said second-named yoke and adapted to engage with the fabric to be reeled, at a point between the guide roller and the winding spindle, and to eXert pressure thereon.

2. The combination with a winding machine having a guide roller and having a winding spindle arranged below the roller, of a cross bar having arms pivotally mounted on the guide roller shaft, a yoke having a central vertical pivotal connection with said bar, and a guide roller mounted in said yoke and adapted to guide the paper or fabric being wound as it passes from the guide roller to the spindle.

3. The combination with a winding machine or the like, having a guide roller and a winding device arranged below the same, of a bar having arms pivoted concentrically with said guide roller, a yoke pivoted to the center of said bar and adapted to swing in a substantially horizontal plane, a roller mounted in said yoke, said roller projecting forwardly to engage with the paper or fabric passing from the guide roller to the winding device, the arrangement being such that the roller may swing in both horizontal and vertical directions in order to equalize the tension on the fabric, and means for adjusting the pressure of the roller against the fabric.

1. The combination with a winding machine having a guide roller and having a winding reel, of a cross bar pivoted to swing in a plane at right angles to the reel, a yoke pivotally mounted on said bar, springs tenddescribed.
