REEL FOR PAPER-MAKING MACHINES.

SPECIFICATION forming" part of Letters Patent No. 653,583, dated July 10, 1900. Application filed February 27, 1.899- Serial No. 707,040. (No model.)

To all whom, it may concern;

Be it known that we, JOHN WARREN MOORE and JOSEPH ATWOOD WHITE, citizens of the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Reels for Paper-Making Machines, of which the following is'a specification.

Our invention relates to certain improvements in reeling and unreeling mechanism for paper-making machines. I

The objects of our invention are to prevent unnecessary waste of the paper-stock, to more rapidly and accurately wind the stock upon the reels, and to provide mechanism by which the paper can be fed from the reels to the slitting-machines. These objects We attain in the following manner, reference being had to the accompanying drawings, in which- Figure l is a side View of our improved reel, showing a portion of the calendering-rolls and a portion of the slitting-machine. Fig. 2 is a front view of the reel looking in the direction of the arrow, Fig. 1. Fig. 3is a sectional View on the line 3 3, Fig. 2. Fig. 4 is a section through one of the clutches. Fig. 5 is a perspective View of the apron for guiding the paper to the reel. Fig. 6 is a sectional detail of the means for longitudinally adjusting the reel-shafts, and Fig. 7 is a modification of the driving-gear.

A is the reel.

B is a stack of calendering-rolls, and O is the slitting-machine.

A are the standards, having bearings a for the reel-shaft D. On the shaft D are two hubs D, each hub having in the present in stance two arms at 01, provided with boxes d at theirouter ends. In these boxes are mounted the shafts e of the rolls E E, on which the paper is reeled. The shaft D can be revolved so as to shift the rolls E E from one position to another by means of a worm-wheel f, meshing with a worm f on the shaft F, geared to a shaft F through a bevel-pinion f and bevelwheel f The bevel-pinion f isloose on its shaft and is secured to the loose portion of the clutch F, the other portion of the clutch being rigid on the shaft F. I The shaft F is driven from any suitable source of power by a" belt passing around a belt-wheelf. By throwing in the clutch the shaft will be revolved and the reel-dru ms will be shifted and the shaft will be locked in the shifted position by means of the worm and worm-wheel gearing. The drums E are driven at a given speed, according to the travel of the paper through the machine. On each drum-shaft e is a clutch E of any of the ordinary forms, so that by shiftingeither of the clutch-levers 6 their respective shafts Q can be throwninto or out of gear with the driving mechanism.

G is the driving-shaft, having a belt-pulley g, which is preferably belted to the driving mechanism of the calendering-rolls. On the shaft G is a pinion g, gearing with an intermediate g on a stud projecting from the frame of the machine, and this intermediate in turn gears with a wide-faced gear-wheel G, Fig. 2', loosely mounted on the shaft D. Meshing with this gear-wheel are pinions g on sleeves 6 adapted to bearings in the arms of a frame D mounted on the shaft D. On the oppo-- site end of each sleeve 6 is a portion of the clutch E The shafts e are coupled to the sleeves e by the clutches E described above. By this gearing or its equivalent the reels are driven at about the same speed as the calenderi ng-rolls, so that as the calendering-rolls deliver the paper thelower reel will windit up.

Two gear-wheels may be used side by side and secured together in place of the widefaced gear-wheel G, or a wheel having external and internal teeth may be used, as shown in Fig. '7.

The shafts e e of the rolls E E can be adj usted longitudinally in their bearings by means of an adjustingscrew it, having a hand-wheel 72. The adjusting-screws h are adapted to threaded openings in the arms (I d, respectively, and adapted to a groove in each shaft E is a collar 79, through which the screw passes. On turning the screw the shaft will be adjusted longitudinally, so that the paper will be properly reeled as it is delivered from the calendering-rolls. The clutch end of each shaft has a keyway for the reception of a key on one part of the clutch, so that it can freely slide within the clutch when adjusted by the screw h. On each clutch is a friction-wheel 1', adapted to mesh with a friction-wheel c" on a driving-shaft I. One end of this shaft I is adapted to a pivot-bearingt' in one of the standards A, while the other end of the shaft is adapted to abearingin an arm i of a rock-shaft I, having another arm i connected by a rod i to an arm j on the rock-shaft J, mounted in bearings on the frame of the slitting-machine O. The shaft J extends from one side of the slitting-machine to the other and has a hand-lever j within easy reach of the operator, so that when it is desired to draw thelpaper from the upper reel and feed it to the slitting-machine all that is necessary is to move the leverj so as to force the friction-wheel t" into contact with the friction-wheel'i of the reel, when the reel will be turned and the paper fed from the reel. It can then be adjusted to the rolls of the slitting-machine without the necessity of the operator pulling the paper, as heretofore.

On the shafts e e are friction-wheels K, to which are adapted suitable friction-levers. In the present instance there are two levers k for each wheel K. These levers are carried by studs 01 on the arms of one of the hubs D. The free ends of the levers are connected together by a bolt 7;, on which is a thumb-nut k On turning the thumb-nut more or less friction can be applied to the brake-levers as required to properly feed the paper to the slitting-machine. The brakelevers k are loose on the stud (i so that they will not interfere with the longitudinal adjustment of the shaft e.

Pivoted at min the present instance to the housings of the calendering-rolls Bis a frame M, in the present instance formed of two arms M and cross-shafts m m. The crossshaft m is the pivot for the frame, and on this shaft are a series of rollers m and on the cross-shaft m are a series of rollers m Passing around these rollers are feed belts or aprons M to direct the paper from the calendering-rolls to the reels. This construction is clearly shown in Fig. 5. In some instances a single wide feed-belt may be used instead of the series shown. The feed-belts pass under the lowermost drum for the paper and conform to the drum and to the paper as it While we have shown simply one weight,.

weights may be used on each side of the frame.

On the slitting-machine O is a drum 0, over which the paper passes from the slitters c to be rolled in rolls for delivery. This drum we mount in suitable bearings, so that it will revolve freely, and on the shaft of the drum is a friction-wheel o, and pivoted to the frame are friction-levers 0 coupled together by a bolt 0 and a nut 0 By turning the nut more or less friction can be applied to the drum, and thus the necessary tension for the paper as it travels over the drum is provided. If it is desired to have a tight roll of paper, the tension is so arranged as to take the strain oif the paper between the reel A and the slittingmachine, as the ordinary paper will not stand the tension required and will tear at this point, and to obviate this we regulate the friction as the paper passes over the drum C so as to produce a tight finished roll without strain upon the paper as it leaves the reel.

The operation of the machine is as follows: The paper from the calendering-rolls is directed at once onto the apron M and fed between the apron and the roll and passes out back of the reel. The operator standing at this point examines the paper and as soon as the paper appears in good condition the refuse is torn oif and the paper as it is fed through is turned around the roll E, which in the present instance is the lower roll of the reel, and the paper quickly winds upon the roll. The paper can be moistened to make it adhere to the roll, if necessary, but with a little care it can be readily started without moistening. The speed of the roll at its smallest diameter is about the same as that of the oalendering-rolls and is driven by slipping belt or friction,so that the paper is rolled as soon as it is delivered until the proper size of the roll is reached. In the meantime the upper roll E, on which the paper has been previously reeled, is in position to have the paper drawn off and fed to the slitting-machine. This is done by operating the lever j, described above, and throwing into gear the friction mechanism by which the paper is unreeled, and the operator can readily feed it to the slitting-machine. Thus the paper is unwound from one reel as it is wound upon the other. As soon as this one reel is discharged and the other reel filled the mechanism for turning the shaft D is thrown into gear, and this shaft is turned in the direction of the arrow 1,Fig. 1. The paper continues to be wound upon a roll E until the roll E is in the position forthe paper to be reeled upon it. The paper while the rolls are in this position passes around the empty roll and is still fed onto the upper roll. When everything is in position, the paper is out between the two rolls and the end of the paper going from the calendering-rolls is drawn around the lower empty roll and immediately this roll begins be used or the reel may be provided with more than two rolls without departing from our invention.
