MACHINE FOR WINDING PAPER WEBS,

SPECIFICATION forming part of Letters Patent No. 339,796. dated April 13, 1886.

Application filed November 12; 1885. Serial No. 182,550.

To all whom, it may concern.-

Be it known that 1, JOHN J. MANNING, a citizen of the United States, and a resident of Great Barrington, in the county of Berkshire and State of Massachusetts, haveinvented certain new and useful Improvements in Machines for \Vinding Paper Vebs; 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 makeand use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has relation to that part or portion of papermaking machines in which the web of made paper as itleaves the papermaking machine proper is cut into strips longitudinally, and the said strips wound upon spools into rolls of suitable size adapt-ed for newspaper-work, book-work, and any class of paper where a continuous web is required. In this spooling or winding apparatus it is very desirable, where more than one spool is used not only to equalize the speed of the several spools and their rolls of web in such a manner that rolls of different diameters can be revolved at velocities corresponding to their respective diameters and still be driven from the same main shaft, but it is also desirable that the several strips of paper into which the web is cut may all be wound simultaneously and evenly upon their respective spools regardless of their diameters, and in such a manner that the paper may be used for the several purposes for which it is intended directly from the spools without rewinding. In other words, the object of my invention is that paper webs of varyingwidths, suitable for printing, paper-bag making, wall-paper, telegraphpaper, or for any other purpose or purposes, may be wound upon the rolls direct from the paper-making machine proper by a method of surface-winding, so that these rolls of wound paper shall be ready for the market without any further process of winding.

In the accompanying two sheets of drawings, Figure 1 represents a side elevation of so much of a paper-machine as is necessary to illustrate my invention, and Fig. 2 is a top or plan view of the same.

(No model.)

Similar letters of reference indicate corresponding parts in both the figures.

In the present illustration of my invention I have shown a machine for surface-winding eight spools simultaneously, and having two friction-cylinders fitted with four spools each; but it is obvious that the number of spools to each cylinder may be increased by increasing the size of the latter, and that the aggregate number of spools ina machine may also be increased by increasing the number of friction or power cylinders. The paper-is taken as it comes from the roll A, over which it passes after leaving the cutters d, to the several spools shown at B, the strips of web diverging to these spools, as clearly shown in Fig. 1. The spool-shafts are mounted in boxes or bearings O, radiating from the axis of the friction-cylinders or power-cylinders D in such a manner that the rolls will adjust themselves upon the surfaces of the cylinders as they gradually increase in size by the accumulation of paper. The boxes 0 are formed in castings E, suitably fastened to the sides of the frame in which the cylinders D are mounted, the shafts F F of said cylinders being rotated and their speed equalized by means of a suitable equalizing device. The uppermost boxes on each side of the cylinders are so located relative to said cylinders that the paper as it is being wound upon the spools which are journaled in the boxes will pass over the crown or arch a of the cylinder as it revolves, as clearly shown in Fig. 1, so as to produce the requisite tension necessary to wind the webs of paper firmly upon the rolls, and to impart a rotary motion to the same solely by frictional contact with the circumference of the cylinder.

For the purpose of the equalizing mechanism, I prefer to use the device fully shown and described by mein another application of even date herewith; but I desire it to be understood that I do not limit myself to any particular form of equalizing device or apparatus for the purpose of effecting an equal rate of speed between the two friction cylinders or drums D D. This equalizing device (shown at G) is operated by means of a pulley, H, and an endless band or belt, I, which passes over the pulleyJ on the main drive-shaft. As the speed of the two power or friction cylinders D D is equalized, it follows that the speed of the rolls, which receive their motion from frictional contact of the fabric wound around them with said drums, is also equalized, so thatthepaper web will be wound evenly or with equal tension upon all the rolls simultaneously. If only one power-drum or friction-cylinder instead of two is used, the equalizing device her'einbefore referred to may of course be dispensed with; but if three or more drums are used instead of two, another equalizing device becomes necessary for the purpose of equalizing the speed between the-whole set. In other words, one of these equalizing devices is necessary for each pair of friction-cylinders, and

where a machine is originally intended for running four of these friction-cylinders,when for any reason it is desired to run for the time being only three of these drums, the fourth one may be flocked out in substantially the same manner as described in my other application to which reference has hereinbefore been made. As above stated, Where more than one friction-drum is used, it is absolutely necessary that the speed between the several friction-drums should be exactly equal, so that they in turn may equalize the velocity of the several rolls of Web bearing against them as they revolve. By this method of surfacewinding I am not alone enabled to run alarge number of spools simultaneously; but I can remove damaged paper from any one of the rolls without the necessity of removing a corresponding quantity of good paper from the other rolls. paper at any time during the operation of the machine, regardless of the status of the rolls wall-paper, or for any other purposeforwhich Again, I can start a fresh roll of already in process of winding, and I can use 7 square or round spool-shafts at pleasure,as may be desired. By running a large number of 40 spools simultaneously I save the time and labor involvedin rewinding the webs upon similar spools, and by cutting the strips of web tothe desired widths for printing-paper, bag-paper, continuous webs of paper are required, I can take the rolls directly from 'the machine and put the paper to the use for which it is intended without further trouble. Those 0onversant with the art of paper-making will readily understand the very considerablesav ing of laborand time which this involves in contradistinction from the method of winding paper as heretofore practiced in paper-mills.

Having thus described my invention, I, claim and desire to secure by Letters Patent of the United States- &

Inapparatus for winding or spoolingrolls of paper by surface-winding, the combination of the following elements: two or more power- '60 cylinders or friction-cylinders, a series of spools arranged in boxes radiating from the axis of said cylinders and adapted to bear by gravity against the circumferences thereof, and an apparatus or device, substantially as described, for equalizing the speed between the said power-cylinders.

In testimony thatI claim the foregoing as my own I have hereunto affixed my signature in presence of two witnesses.
