APPARATUS FOR WINDING PAPER WEBS INTO ROLLS.

SPEQIPICATION forming part of Letters Patent No. 320,375, dated June 16 1885.

(No model) To all whom it may concern:

Beitknown that I, J OHN J. MANNING, a citizenofthe United States,andaresident ofGreat Barrington, in the county of Berkshire and State of Massachusetts, have invented certain new and useful Improvements in Apparatus for Winding Iaper \Vebs into Rolls; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification, and in whichv Figure 1 is a side elevation of as much of a paper-making machine as is necessary to illustrate my improvement. Fig. 2 is a plan view, of the same; and Figs. 3 and 4 are respectively an axial sectional view and a side view, with one conical cogwheel removed, of one of the equalizingpulleys.

Similar letters of reference indicate corre .sponding parts in all the figures.

My invention has relation to that portion of a paper-making machine in which the web of paper is cut and wound into rolls and it consists in the improved construction and combination of parts of a device for equalizing the tension at each roll of paper, as hereinafter more fully described and claimed.

In apparatus for winding the cut web of paper into rolls there has been agreat drawback, in the shape of the impossibility to equalize the speed of the several rolls in such a manner that rolls of different diameter can be revolved at differentspeeds corresponding to their respective diameters and still be driven from the same main shaft, so that the paper after it is cut into strips may be wound evenly upon all the rolls regardless of their diameter, and by overcoming this drawback I accomplish a great saving in the manufacture of paper, inasmuch as in machinery heretofore used it has been necessary to remove as much good paper from the other rolls as damaged paper from one roll in the case that the paper on one roll should be damaged by some accident or other, as well as I also accomplish that a new roll may be started while the paper is still being wound upon the other rolls. In short, I accomplish that the several rolls and their shafts may be revolved at a speed corresponding to their diameter, and that the said result is performed automatically.

In the accompanying drawings, the letter A indicates the roll of paper, which is to be cut in suitable widths to be wound upon the rolls, and the web passes irom the roll A under a roller or cylinder, B, then upward over a small roller, (J, between the revolving shears or cuttei s D, which cut the web into suit able widths, and between two rollers or cylinders, E and and F, from which rollers the several webs or strips of paper pass down to their respective rolls, which are wound each upon a shaft, G, journaled transvcrsel y in bearings in the frame of the machine, the said bearings being of such a construction that the shafts may be lifted out of their bearings. The shafts, of which there are as many as there are rolls to be wound and webs of paper out, have small pinions H, secured upon them inside of the bearings, which pinions mesh with pinions I, secured upon the ends of shafts J, which are provided with pulleys K or similar gears, such as cog-wheels.

In the drawings the gears K are shown as pulleys having belts passing over them, and I shall refer to the gears as pulleys in the specification; but desire it understood that I can substitute any other suitable manner of gearing without departing from the spirit of my invention. Belts L pass over the pulleys, and each pair of belts of adjoining pulleys pass over two pulley-rims, M, forming parts of my improved equalizing-pulley. Each of these equalizing pulleys N, with their two rims, are placed upon shafts, O, which have common pulleys or gears I, over which pass belts, Q, which again pass over the two rims of an equalizing-pulley, R, upon the drive or power Shaft S.

In the drawings have been shown four rolls, and consequently four shafts, J, and consequently two equalizing-pulleys, N, are shown, and one equalizing-pulley upon the driveshaft, and it follows that it more than four shafts are used the number of equalizingpulleys N is increased at a rate of one pulley for each pair of shafts and belts, and the number of equalizing-pulleys It is increased at the rate of one for each pair or less of equalizingpulleys N, each of which pairs of equalizingpulleys are again provided with suitable belting, which passes to another equalizing-pulley, the aforesaid pulleys having separate shafts and belt-pulleys, the number of equalizingpulleys decreasing gradually by division with two in the number of pulleys until one equalizing-pulley is reached, which is placed upon the drive-shaft. It follows that if an uneven number of rolls and shafts is used, one of the pulleys N will only have one belt passing over it and Will have the two rims revolving to gether, the manner of connecting the said rims being described hereinafter. If only two shafts and rolls are used, one equalizing-pulley only is used.

The rims M of the equalizing-pulleys are socured by means of spokes or solid pulleybodies to sleeves or hubs, T, which turn upon the shaft, and are confined from lateral play by means of flanges or collars U upon the shaft. and one ofthe rims is provided at its inner edge with an outwardly-projecting flange, V, which will prevent the two belts passing over the two pulley-rims from interfering with each other or becoming fouled with each other. An arm, W, formed into a stud, X, at one end and into a eountel'poise, Y, at its other end, is keyed with its hub Z upon 1 the shaft between the hubs ofthe pulleys, and a cone-pinion, A, is journaled upon the stud, and secured by a jam nut, B, meshing with two conical cogwhe'els, (JC, secured upon the inner ends of the hubs of the pulleys integral with the same or simply secured upon them. It'will now be seen that as the shaft is revolved and the arm with it the cone-pinion will simply engage the cog-wheels at diamet trieally opposite places,and turn them around with it as it is revolved as long as the tension on both pulleysis even; butthe moment the tension upon one pulley becomes greater than upon the other pulley the cog-wheel upon the hub of that pulley will turn the conepinion, the said pinion revolving with the aim at a greater speed than the pulley, and the cone-pinion turning upon its stud will turn the cog-wheel upon the hub of the other pulley and force the said wheel and pulley to travel faster, thus equalizing the tension upon the respective belts, and causing the two pulleys driven by and upon the same shaft to revolve with as much different speed as the i difference is in the tension of the belts upon the said pulleys, and consequently upon the 1 rolls of paper. In this manner it will be seen that these pulleys serve as equalizers for the several shafts revolving in concert, automatically regulating the speed according to the tension upon the several pulleys. It follows that, although these pulleys are especially adapted to and intended for paper-cutting apparatus for paper-making machinery, the pulleys may be used in any other machinery, in-which it is desirable to automatically regulate the speed of pulleys or cog-wheels according to the tension upon the same. By using these pulleys any damaged part of the web winding upon one roll may be removed, and the roll started again without the neeessity of removing any paper from the other rolls so as to equalize their thickness and consequently their speed of revolution, or a roll may be removed and a new roll started while the other rolls continue to wind the paper upon the large rolls already formed.

llavingthus described my invention, I claim and desire to secure by Letters Patent of the United States 1. In an apparatusfor winding rolls ofpaper from thecuttingmeehanism,thecombination of the removable winding-shafts having pinions secured upon them, the shafts having pinions engagingthepinions ofthewinding-shafts, and having suitable gears secured upon them, the equalizing-pulleys constructed as described, and connected to revolve the gears in pairs, the shafts having thesaid pulleys placed upon them, and means, as described, for equalizing the tension and speed of the said shafts, as and for the purpose shown and set forth.

2. In apparatus for winding rolls of paper from the cutting mechanism, the combination, with the cutting mechanism, of the windingshafts having pinions secured upon them, the shafts J, having pinions 1 and pulleys K, belts L, equalizing-pulleys N, shafts O having the equalizing-pulleys N and the pulleys P, belts Q, and the drive-shaft S, having the equalizing-pulley It, as and for the purpose shown and set forth.

In ttstimony that I claim the foregoing as my own 1 have hereunto aftixed my signature in presence of two witnesses.

JOHN J. MANNING.
