MACHINE FOR WINDINIG PAPER.

SPECIFICATION forming part of Letters Patent No. 545,449, dated September 3, 1895.

Application filed December 31, 1894- Serial No. 633,481. (No model.)

To all whom it may concern.-

Be it known that I, NORMAN H. BROKAW, a citizen of the United States, residing at Kaukauna, in the county of Outagamie and State of Wisconsin, have invented certain new and useful Improvements in Machines for Winding Paper, of which the following is a specification.

My improvements especially relate to ma chines for dividing sheet-paper fed from a large wide roll into relatively narrow sheets and rewinding them in smaller rolls on a separate shaft. Ordinarily the paper is fed from the large roll through a slitting apparatus and then wound directly in smaller rolls ona shaft. It is also quite common in this class of apparatus to pass the paper from a large roil through slitting apparatus, over a drum orcylinder, and onto a rewinding-shaft, power being applied to the drum or cylinder, the rewinding-shaft being driven by friction from the drum and being arranged in sliding boxes to enable it to recede from the cylinder as the rolls of paper on itincrease in diameter. According to my invention I may employ ordinary slitting apparatus and an ordinary drum or cylinder; but power is not applied to the drum in my invention. I mount the rewinding-shaft on swinging arms so arranged as to present the rewinding-shaft to the surface of the cylinder, and I provide gearing for posi tively driving the rewinding-shaft from a shaft in line with the axis about which the arms which carry the rewinding-shaft swing. By this arrangement I am enabled to wind the paper more tightly, prevent looseness at the center of the roll, and a consequent tendency to telescope- The organization which I employ prevents the rewinding-shat't from springing, the drum, in connection with the swinging arms, preventing the paper from pulling unduly on the shaft and also preventing the paper from being wound unevenly or being torn.

In the accompanying drawings, Figure 1 is a plan view of a machine embodying myjmprovements, with the slitting apparatus removed; and Fig. 2'is a side elevation thereof. The main frame A may be of any suitable construction adapted to support the mechanism. A shaft B, on which the unslit roll of paper is wound, is mounted in suitable beartion and the details-of which form no part of my present invention.

A drum or cylinder F on a shaft f is mounted .in suitable bearings f on the top of the frame A, and this shaft may be provided with a hand-wheel F. An expansion-shaft G, of suitable well-known construction, is mounted in bearings g at the upper ends of a pair of arms H, the lower ends of which are mounted on a shaft I, mounted in a frame J. The

shafts G and I are located a proper distance apart to hold the rewound paper in a suitable relative position to the cylinder Fsuch that the paper shall pass over the top of the cylinder downwardly a short distance and then under the shaft G. swing toward and from the cylinder, and as the diameter of the paper on the shaft G increases the arms 11 swing in thedirection indicated by the arrow-away from the cylinder. The weight of the arms and parts carried thereby is, however, sufficient to insure such a frictional contact between the paper on the shaft G and the cylinder F as to drive the lattercoincidently with the shaft G.

Power is applied to a driving-pulley K- on a shaft I. in the same axial line with the shaft I, but not connected therewith.

Suitable clutch mechanism M, operated by rods and levers N, may be employed for connectingand disconnecting the driving-pulley K with the shaft L, which is provided with a pulley 0, connected by a belt 0 with the slitting apparatus, and a pulley P, connected by a beltp with a pulley Q on the shaft G. As the axis of the driving-shaft L coincides with the axis of the shaft 1, about which the arms H move, the shaft G may be continuously revolved, no matter what may be its position with reference to the cylinder F. The shaft B revolves freely and the paper unwinds from the roll without hinderance.- The drum 0 is of large area, presenting an extended surface to the web of paper which it supports immediately before it is wound onto the rewinding-roll.

Care is taken in this machine to avoid un- The arms H are free to due tension, which would tend to stretch the paper and thus tear it. The guides, it will be observed, are all beneath the paper and are not arranged over it, so as to press it down and form loops in it, which would tend to stretch it.

So far as I am aware in this'class of machines the rewindi'ng-shaft has never before been mounted in swinging arms and positively driven, as above described, and

What I claim is 1. The combination, substantially as hereinbefore set forth, a main frame, an unimpeded, freely revolving shaft for supporting a roll 'of paper to be re-wound, of a frictionally driven drum over which. the paper to be rewound passes, and a positively driven rewinding shaft mounted to recede from the drum as the diameter of the paper wound on the shaft increases, said drum being so mounted that it supports the ro-winding shaft to relieve it from the weight of the paper and to prevent it from springing or bending.

2. In a machine for re-winding paper, the combination of a main frame, an unimpeded, freely-revolving shaft for supporting a roll of paper to be rewound, a re-winding shaft, swinging arms on which this shaft is mounted, a driving shaft in line with the axis about which the arms swing, driving connections between the driving shaft and re-winding shaft, whereby the latter is positively revolved to wind the paper upon it, and a drum over which the paper to be re-Wound passes and which supports the weight of the re-winding shaft and the roll of paper thereon, there "by preventing the shaftfrom springing or bending.

3. The, combination, substantially as hereinbefore set forth, of a main frame, a shaft for supporting a roll of paper to be slit and re-wound, slitting apparatus through which the paper passes, a shaft on which the paper in smaller rolls is re-wound, swinging arms on which the re-winding shaft is mounted, a driving shaft in line with the axis about which the arms swing, a pulley on the driving shaft connected by belt gearing with a :pulleyon the re-winding shaft, a cylinder of large surface area mounted in bearings be low thebearings of the re-winding shaft and arranged to support the re-winding shaft and the roll of paper thereon to prevent it from springing or bending.

In testimony whereof I have hereunto subscribed rny name.
