To all whom it may concern.

Be it known that we, ARCHER EDWARDS and RICHARD JOHN EDWARDS, subjects of the Queen of Great Britain',residing at London, in the county of Middlesex, England, have invented anew and usefullmprovement in Machinery for Straightening and Winding Cloth or Paper or other Flexible Material in Long Lengths, (for which we have obtained a patent in Great Britain, No. 8,129, dated July 4, 1885,) of which the following is a specification.

Our invention relates to improvements in apparatus for straightening and winding emery or glass cloth or paper made in long lengths; but it may be applied also to wallor printing papers or other such flexible material which it is required to flatten and wind or reel easily in rolls.

The object of our improvements are, first, to provide means by which the irregular edges of the fabric are straightened or brought up to a true line, and this at the same time that the surface is being flattened under pressure; second, to provide means by which it is simultaneously wound into a roll while the surface is flat and the edges straight, and, third, to provide means by which the entire apparatus can be readily moved from place to place, as required, while the moving parts can be instantly set in motion or stopped wherever the apparatus may be placed. WVe attain these objects by the mechanism illustrated in the accompanying drawings, in which-- Figure 1 is a side view of the apparatus when in action; Fig. 2, a top view of the same; Fig. 3, a View of the opposite side of the apparatus when not; in motion; Fig. 4, a back view of the apparatus. Figs. 5 and 6 are side views upon a larger scale of the bearing for the reel-spindle closed and opened, respectively.

Similar letters refer to similar parts th roughout the several views.

Supposing our invention to be applied to emery or glass cloth which is made in long lengthsand in the process of manufacture is hung up to dry in folds suspended from racks or rollers and which it is then necessary to reel, so as to form rolls, it is found that such material, when dry, is somewhat stiff and inflexible, especially laterally, and that it is difficult or impossible to straighten it so that when wound or reeled the edges are uniform and even, its tendency in winding being to project irregularly at its sides or edges, which are liable to be damaged if the material when flatis forcibly pressed or guided laterally for the purpose of bringing its edges into a true and even line.

a a, are two vertical parallel frames of-metal' or other suitable material held together by stays where necessary. Across these frames at their upper endis arranged a strong shaft 17, upon which is fitted and firmly fixed, so that it cannot revolve, a cylinder or drum or part of a drum 0 of metal, or wood, covered with india rubber, leather, or other suitable material, of considerable diameter, and of a length somewhat, greater than the width of the material-to be operated upon. In front of the drum we fix a board or guide (I, up which the material is drawn in the way hereinafterdescribed, from a box in which it has'been stored, or from the fioor,'or from the racks themselves upon which it has been dried.

The guiding-board cl is hinged at 2', so that it can be turned up out of the way when required, and it has two parallel sets of pins f, somewhat wider apart than the Width of the material, which pins guide and tend to straighten the edges of the material 6, which passes from the board d over the upper side of the fixed drum 0, and around the latter to its lower side, and thence to a spindle or reel. g, revolving in hearings in the lower part of the frame a, around which reel it is wound as the spindle or reel is made to revolve.

For a sufficient part of its upper circumference the drum 0 is fitted with parallel projecting flanges it, between which the material is drawn, and these flanges being fixed at a distance apart very slightly greater than the width of the material 6 the latter ,is straightened by the pressure of-its edges against the flanges h, and is delivered from the drum 0 to the winding-reel g with its edges properly straightened, so that when wound upon the reel they'lie perfectly true. The lateral press ure against the edges of the material, being applied where the latter is stretched round the curved surface of the drum 0, is capable of giving sufficient force to straighten the material e without injuring or bending up the edges as would be the case if it were at tempted to force them laterally while they were lying upon a flat surface. The part of the drum 0, which is not passed over 'by the material 6, may be left open as shown.

In order to keep the material 6 in sufficiently close contact with the drum 0, while it is passing over the latter, a transverse shaft or bar i is arranged across the machine above the drum 0, and to this bar is hinged or pivoted a frame 7.: of cast-iron or other suitable material, the outer end of which is provided with bearings carryinga roller Z, which presses down the material 6 against the drum 0 below. The frame 7.; also carries between the roller and the bar 2', upon which it is pivoted, as described, two or more bars 721, parallel with the axis of the drum, their lower side being somewhat rounded and coming (when the roller is pressed down) within a short distance of the surface of the moving material, which is thus kept down and prevented from rising or buckling.

NVhen desired, the frame 7;, with the roller Z and bars m, can be raised, as shown in Fig. 3, from the material 6 around the centert'for the purpose of introducing or adjusting the material, and it maybe partly balanced so as to. be more readily so raised, when desired. The frame can be held down with any de sired pressure by adding or removing weights m carried by the bar m and the roller Z, which is preferably covered with leather, india-rubber, or other sufliciently soft and elastic material, is prevented by its friction from revolving too freely.

hen the edge of the material 6 is very much curled up we sometimes arrange lateral curved guides, (shown in dotted lines at 72. 7t in Fig. 2,) between which it passes so as to be gradually straightened or flattened to some extent before it passes between the flanges upon the drum, as already described; or where Very thin paper is being treated, the curled-u p edges may be so flattened down by a blast of air directed upon them from a fan or other convenient source, as shown at 71.2 in Fig. 1.

Before passing from the drum 0 to the winding-reel g, as already described, we make the material pass over a roller a, revolving in bearings carried by a lever n, the outer end of which is provided with a balan ce-weight n so that the roller is pressed up with any desired force.

In Figs. 1, 3, and 4, A is the floor of the room in which the apparatus is to be worked. 0 is a longitudinal driving-shaft ru nning below the floor, and driven by steam orother power. 19- is a driving-disk, one of which is fixed upon the shaft 0 at every position where the apparatus is required to be worked. This disk p is angular at its circumference, and fits between two disks 4" .9, carried and turning upon a pin or stud t at the lower end of a lever to. The space between the edges of the disks r 8 is made ,to correspond with the edge of the disk 13, and they are adjusted at the proper distance apart by a nut v. The lever 11. is fixed upon a shaft or center 20, and the disk 7' has attached to it a pulley at, which drives by a band ac a corresponping pulley 00 which turns freely upon the shaft to, and has attached to it a toothed pinion ,e, which in turn drives the toothed wheels .2" .2 the lat ter of which is fixed upon the spindle of the winding-reel g. The lever a has connected with it a handle a, by which it can be i turned upon the stud w and fixed in the required position in the guide Fi 1, so that the pulleys 'r s can be brought into contact with or removed from the driving-disk p. The lower end of the lever u, and the disks 0' 3 pass through an opening in the floor A. When the apparatus has been brought into the proper position and the end of the material c which is to be straightened and wound has been brought over the drum 0 and roller 1 n to the reel g, the handle a is moved until the disks 0 s have been brought into contact with the disk 1), as shown in Fig. 1. The reel g is then set in motion and the material 6 is wound upon it. being first partly straightened at its edges as it passes up the board 61 by the pins ff, at the sides of the latter, then further flattened as it passes over the drum 0 and under the bars m m and roller Z, its edges being straightened while it is in a curved form by 1 the flanges h 71..

\Vhen the hole of the; material has been strightencd and wound, as described, the handle to is raised and the disks r .9 disengaged from the driving-disk p, and r the reel g with the material wound upon it is removed from its bearings and another one substituted for it, the entire apparatus being iremoved upon the rollers B to afresh position, where the disks 0* s can be put in contact with another driving-disk 19 upon the shaft 0. In order to facilitate the speedy removal and replacement of the reel the hearings in :which its axle rests and turns are made as shown in Figs. 5 and G.

C is the body of the bearing, and D its cover, which is hinged at E. A bolt F is also. hinged to O at the other end and fits into a. slotted opening in the end of the cover D, so that 1 when the nut of the bolt F is slackened the latter can be turned down and the coverD opened, as shown in Fig. 6.

G is a spring fixed tothe-end of O by'which 1 the cover D is retained securely in either its closed or open position.
