Application filed August 28, 1905. Serial No. 276,042.

To all whom it may concern:

Be it known that I, JAMES W. HARRIS, a citizen of the United States, residing in Ham- .ilton, Butler county, Ohio, (post-office adthe following description, taken in connection with the accompanying drawings, in

. which 7 tion, upon an enlarged scale,

Figure 1 is a side elevation of a winder exemplifying my invention; Fig. 2, a front elevation of the same; and Fi 3, a vertical sec in the plane of line a of Fig. 1. p

In the drawings, 1 indicates a pair of housings; 2, a driving-roll journaled therein and having a length somewhat in excess of the width before slitting of the widest Web to be dealt with 3, a second driving-roll mounted in the housings parallel with the first one; 4, caring connecting the two rolls so that the rol s turn in op osite directions at equal peripheral rates of speed, the illustration showing the two rolls as being of equal diameter,

under which conditions the gears 4 equal each other in size; 5, the shaft of either one of the drivin -rolls, through, the medium of which the ro ls may be operated by power; 6, a guide-roll disposed parallel with and above the driving-rolls and serving to guide the slitted web coming from thesource of supply to the winders; 7, a pair of housings independent of the housings 1 and disposed para lel with and at a selected distance apart from each other at the outer side of the driving-roll 2; 8, guides carried by or formed with the top edges of the housings 7, these guides declining toward driving-roll 2; 9, ournal-boxes sliding on the uides 8; 10, a drum-shaft, on which a roll of paper is to be wound, removably mounted inthe boxes 9,

, the construction for permitting the insertion and removal of the drum-shaft being of any character suitable or usual in windersjll, an ldle-wheel mounted in each of the housings 7 at the inner end of its top uide, this wheel being by preference a sproc et-wheel; 12, a similar idle wheel at the outer end of the guide of each of the housings 7; 13, a similar idle wheel mounted in each of the housin s 7 below its wheel 11; 14, a similar idle wheel mounted in each of the housings 7 below its wheel 12; 15, an idle sprocketw'heel mounted in each of the housings between the wheels 13 and 14; 16, a chain, one for each of the housings 7, engaging all of the wheels of the housing and ha'ving its ends secured to the sliding-box 9, whereby the movement of drum-shaft 10 to and from driving-roll 2 is accompanied by movement of the pair of chains; 17, a hub loose on the spindle of sprocket-wheel 15; 18, a weight carried by an arm of this hub and radially adjustable with reference thereto; 19, a clutch for each of hubs 17, whereby the loose hub and the weight carried by it may at will be locked to its sprocket-wheel 15 in selective angular po sition with reference thereto; 20, a roll of paper being wound upon drum-shaft 10; 21, a shaft enga ing the two chain-wheels 14, this shaft being ast to one of the wheels, the lefthand one in Fig. 2, and loose in the other wheel; 22, a ratchet on shaft 21; 23, a ratchet lever mounted on shaft 21 and adapted to cooperate with the ratchet 22 in turning shaft 21; 24, a second ratchet on shaft 21; 25, a stop-pawl cooperating with ratchet 24, and 26 clutches to serve in locking shaft 21 to thesprocket-wheels 14.

As thus far considered the parts are adapted for the winding of a single roll 20 of paper or other material. Turning driving-roll 2 by power causes the rotation of the roll 20 by surface friction in the manner usual in surface-driven winders. As the roll enlarges as the result of winding its drum-shaft automatically recedes from the driving-rolls-2, and the inclination of the guides 8 causes the drum-shaft and the roll being wound upon it to exert a portion of their gravity in maintaining frictional drivin contact between the roll of paper and the dr1ving roll; but in the windin of paper, while it is necessary to maintain sufficient friction to do the work, it is desirable to avoid excessive pressure. If the weight of the drum-shaft and its accumulat ing paper he depended upon to produce the necessary driving friction, then it is manifest that the gravity effect must be sufficient when the accumulated roll of paper issmall, and this gravity effect may therefore be excessive when the roll of paper gets large. It is the purpose of the weights 18 to compensate for the increasing gravity of the roll being wound. Giving consideration only to the winding being done at the right in Fig. 1, being the winding-roll 20, we will start with the practically empty drum-shaft 10, just starting upon its winding work. The gravity of the parts to produce the driving friction is comes more efficient in producing the driving contact. As the roll of paper thus increases in size and weight the boxes 9 move outwardly, and acting on the chains and the weights move the weights angularly upward, the gravity effect of the weights 18 thus constantly lessening as the gravity eflects of the roll of paper constantly increases. Eventually the roll of paper has so increased in size and weight that even its unaided gravity would produce heavier pressure upon the driving-roll than is desirable. At this time the weights 18 should have reached the neutral vertical position over their axes, and upon passing that position their gravity effect instead of becoming added to that of the roll of paper becomes subtracted from it, the weight thus acting first as an addition to and then as a subtraction from the gravity of roll of paper so as to com pensate for the constantly-increasing weight of the paper-roll.

The weights 18 being clutched and un clutched from their sprocket Wheels by means of the nuts 17 may be set in any desired angular position. Thus instead of starting the winding with the weights in their most efficient or horizontal position they may be set initiallyin some angular position above the horizontal, and when not wanted they may be unclutched and allowed to hang idly downward.

It may and often does happen that the paper is unequal at the two edges of the web being wound, the result being a tendency to form a tapering roll or a roll more solidly.

wound at one end than at the other. The two weights 18 being independent of each other may be utilized in remedying this defect. Thus it being desired toput an extra strain upon one edge of the paper the Weight 18 corresponding withthat edge of the paper may be angularly adjusted to a more efficient position or the weight corresponding with the opposite edge of the paper may be adjusted to a less efficient posit-ion or may be unclutched so as to hang idly down. Again, under conditions of winding where the weights 18 are not called for in either increasing or diminishing the general pressure upon the paper, conditions under which both weights would be unclutched and hanging idly downward, either one of the weights may be clutched in proper position and brought into service in producing an extra heavy winding strain at one end of the roll being wound.

It will be understood that quite regardless of whether or not the weights be in service the weights at the opposite ends of the roll of paper are independent of each other. Furthermore, it will be obvious that the purpose of the weights 18 is to endow the roll of paper with an adjustable and a varying gravity effeet, so to speak, and that the chain-and-gear arrangement illustrated represents merely a satisfactory mechanical construct-ion by means of which the weights are brought into desired operative relationship with the drumshaft.

Then the roll of paper has been wound to the desired extent and it is desirable to sever the web and remove the roll, it is necessary, or at least highly desirable, that the roll be shifted outwardly away from cont act with the driving-roll 2. In order that this may be done, the clutches 26 are thrown into engagement, thus locking both sprocket-wheels 14 to shaft 21, after which ratchet-lever '23 may be operated to slide the boxes 9 and the roll of paper in an obvious manner, and-when this is done the parts are retained by the stoppawl 25. The drum-shaft, with its roll of paper, having been removed and a fresh drumshaft placed in the boxes 9, the stop-pawl 25 may be released, the pawl or ratchet 22 being at the same time released, if desired, thus permitting the drum-shaft to go into position againstthe driving-roll, after which clutches 26 may be released, leaving both of boxes 9 free to move independently under the influence of the winder or free to be moved independently by hand in ordinary adjustments, while the roll of paper is being started or while it is still so light and small as to permit of hand adjustment. During the operations of the ratchet-lever 23 the hubs of the weights 18 may be either clutched to or unclutched from their sprocket-wheels 15, preferably the latter.

The two housings 7 are. adjustable in position along the driving-roll and also in distance apart, and they may thus be adjusted for Winding a web corresponding in width with the greatest capacity of the driving-rolls, or they may be adjusted closer together to suit either a narrower web coming to the eneral winder or to a division-slit from a wi er web coming to the general winder. In Fig. 2 it is IIO assumed that there is coming to the general times winder a comparatively wide web slitted into two divisions of unequal width, the'narrower one going to form the roll 20/ Proceeding further with the drawings, 27 indicates a housing Similar to housings 7, but disposed u on the opposite side of the pair of driving-rolls; 28, a second similar housing to form with housing 27 a pair of housings for the support of a second roll of paper, this pair of housings being equipped in all respects the same as housings 7; 29, the roll of paper being formed upon a drum-shaft supported by this second pair of housings, this second roll having. surface contact with driving roll 3; 30, the web of paper cornin to the general winder and slitted into two ivisions for the production of the two rolls 20 and 29; 31, the narrower division of the web on its way to roll 20, and 32 the wider division of the web on its wa to roll 29. i

T 1 1 Fig.2 it will be noticed that housing 27 is disposed at the left of the plane of the inner one of housings 7, thus permitting paper 32 having one edge in the same plane as one edge of paper 31 to go pro erly to the drum shaft carried by the secon pair of housings. The two driving- rolls 2 and 3, moving at equal peripheral rates of speed, causes the two rolls of paper to be wound at equal peripheral rates, and analysis will show that the run of the paper on its way to the point of contact is unaffected by variations in the diameter of the rolls being wound or in differences in the diameters of two rolls being simultaneously wound.

Additional pairs of housings may be employed, as represented for instance, by the housings 32 and 34, thus permittin three divisions of a wide web to be simu taneously wound, and this principle may be carried to any extent desired, the alternate rolls being wound by driving contact with one of the drivin -rolls, while the intermediate rolls are wound by contact with the other one of the driving-rolls.

When the general winder is in operation winding a plurality of rolls of paper, one roll at least being driven by one of the drivingrolls and one or more of the others being driven by the other driving-roll, both edges of each section of paper being wound are eX- posed, and there is an abundance of room between the edges of two webs being wound by the action of either one of the driving-rolls. In other words, no matter how many of rolls of paper are being wound a single one of the driving-rolls engages alternate paper-rolls only, thus leaving a gap between the webs as wide as the intermediate web beingv ound b the action of the other driving-roll, an abumf anee of working room between the edges of webs thus being provided. If one of the webs becomes broken or is purposely broken in order to skip a defect, the remaining webs may 'sai weights pertaining to the individual rolls may, 1n an obvious manner, be utilized in adjusting the frictional pressures of the individual rolls of paper relative to each other. Thus the weights 18 pertaining to one roll of paper might be doing light duty or be entirely out of action, while the weights pertainlng to another 'roll of paper were doing heavy duty, it being thus possible to adjust the strains, not only upon the two edges of the same web, but also upon the several webs with reference to each other.
