PAPER-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent No. 535,326, dated March 5, 1895.

Application filed December 19, 1894- Serial No. 532,302- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM R. FARNS- WORTH, a citizen of the United States, residing at Turners Falls, in the county of Franklin and State of Massachusetts, have invented new and useful Improvements in Paper-Winding Machines, of which the followingis a speci fication.

The object of this invention is to improve the construction of paper winding machines to the ends of increased efficiency and evenness in the winding operation, and of rendering the winding machine of unusual convenience and availability for the mounting therein, and removal therefrom, of the winding arbor with the fully or partially wound roll of paper, or for the placing of the windingroll out of pressure contact with the pressure roll to permit the splicing of the ends of paper or for other purpose.

The invention consists in combinations of devices, and in the constructions of certain of the devices, all substantially as will hereinafter fully appear and be set forth in the claims.

Reference is to be had to the accompanying drawings, in which- Figure 1 is a side elevation of my improved paper-winding machine. Fig. 2 is an opposite side elevation of part of the machine. Fig. 3 is a plan view. Fig. at is a vertical sectional View through one of the slide-supports for the separable journal-bearing for the winding roll, which involves novelties of construction to be hereinafter more particularly referred to. Fig. 5 is a perspective view of a double form of the improved paper-winding machine.

Similar characters of reference indicate corresponding parts in all the views.

The machine of this invention comprises suitable framing and supports, and as shown, has the side standards, A, cross-braced or tied, and has as a part or fixture thereof the opposing uprights, A the upper edges, a, of both being similarly oblique and provided with dove-tail ribs, 10, on which are movabl y fitted the slides, b, on which are mounted the journals for the paper-winding roll, B.

The roll, 0, which is mounted in the fixed journal boxes, 0, at the top of the frame, is

the pressure drum, its axis of rotation being invariable.

The winding roll is so mounted on the slides therefor that as the diameter thereof increases 5 5 as the winding-on of paper progresses, the axis of the winding-roll will automaticallyrecede from the pressure drum while the roll of paper making thereon is always circumferentially in pressure bearing against the pressure drum.

The slide, 17, has the journal-box, d, (for each end bearing of the arbor 0f the windingroll, 13,) connected thereto for a slight swiveling movement whereby the periphery of the roll of paper being made may conform throughout its entire line of contact to the pressure drum, whereby any unevenness in the thickness of the paper which may be found at either end of the roll, may be compensated for, and as specifically shown,although departures may be made from such specific means without departing from the invention,-each journal box, or block, d, has, depending below its base, the stud, 01 which enters a socket, b therefor in the slide, 1). There is connected with each journal-box carrying-slide, b, at each side of the machine, a sprocket-chain, h, for which are the supporting and guiding sheaves, c', 2', and the sprocketwheel, j, said chain having a winding engagement around these wheels. Each chain has the take-up device, exemplified in the turnbuckle, e, which is merely for the purpose of having the chain run with proper freedom and without too much lash as well known in sprocket-wheel and chain devices. A second turn-buckle, 30, is comprised in each sprocketchain at its connection with the slide, 6, so that by letting out or taking up the turn buckle, 30, at the one side or the other of the machine, the axis of the winding-roll may be inclined in a very slight degree from its parallelism with the adjacent face of the pressure drum. Each of these journal boxes for the 5 winding-roll is, as shown in Figs. 1 and t, constructed with upper and lower members, 15 and 16, the upper or cap member being hinge-- connected at 17, to the base member, 15.

The separable j ournal-box is held closed by too the cam-ended handle-lever, f, which is pivotally mounted between the duplicated arms,

g, which have their lower ends pivotally connected to the base section, 15, of the journalbox. Thus is provided a convenient means for enabling the removal of a fully wound roll of paper and the mounting in the journal supports therefor of the new winding roll, or arbor, for the roll of paper next to be wound thereupon. By properly swinging the camended handle-levenf, at each journel-box, and then swinging such lever on the supporting arms, g, the hinged upper section of the journal-box may be released and unobstructed to be swung open; and the reverse of these operations is only necessary to confine the new winding roll when set in the journal-boxes.

The sprocket wheel is so mounted and applied that the winding roll may have its receding motion away from the pressure-drum, the sprocket and chain connection in no wise interfering with such movement; but there is combined with each sprocket wheel means for imparting thereto, at pleasure, rotational movements whereby the chains, h, may cause the slides, b, to carry the Winding roll at any distance from the pressure drum which may be requisite or convenient for any of a nu m.- ber'of reasons. This means, as here shown, consists in the ratchet-wheel, 7c,fast on the shaft, Z, on which the sprocket-wheels], j, are also fast,and the lever, m, loosely hung on said shaft, Z, and having the driving pawl, 12, which at pleasure may be swung into en gagement with the ratchet-wheel, 70, so that by a swinging reciprocatory movement of the lever, the journal-supports for the windingroll may be moved as far as necessary in a direction against the gravitation of the Winding-roll and sliding journals therefor.

0 is a detent for engaging the second ratchet- Wheel which is fixed on the shaft Z to temporarily hold it and parts with which it is connected from retrograde movement, so long as such shall be desired. Of course it is understood that when the winding machine is being operated for the winding of paper onto the Winding roll, the pawl-carrying lever, m, and the detent, 0, are in their positions of disengagement, as shown by the full lines in the drawings.

Inasmuch as the pressure of the windingroll and roll of paper thereon against the fixed pressure drum, 0, is variable, according to the extent of progression of the winding operation and the correspondingly increased size and weight of the roll of paper, counterpoise devices are applied, the tendency of which is to. exert the greatest pressure upon the Winding-roll in a direction transversely of its axis, and toward the pressure-drum at the initial part of the winding operation, such pressure gradually decreasing as thesize of the roll of paper being wound, increases, so that the paper will be wound equally solid and closefrom its axis to its circumference, and as an efficieut means to this end I have provided on the shaft, Z, (preferably at the end opposite the ratchet-wheel, 70,) the fusee, or snail-cone, Z,

the cord, or, having one end in engagement with one .of the larger spiral convolutions of the snail-cone, an elevated guiding sheave, '0, over and around which the cord passes, and the counterweight, w, connected to the other end of the cord. This device is so arranged. and adjusted that the draft of the weight and cord, 21;, u, is on one of thelargerconvolutions of the snail-cone when the axis of the roll of paper is nearest the pressure drum, at which time the weight of the paper-roll is the least.

As the machine is running under usual conditions, the ratchet and sprocket-wheels, lay, and the chain, h, are free so that as the roll of paper makes, the chain has its progressive movementin the direction of the arrows shown in Figs. 1 and 2, against the stress of the weight, w, through the medium of the chain, as affected by said weight and intermediate connections, the snail-cone also having its rotational movements as indicated by the arrow adjacent thereto, Fig. 2. Thus the farther the winding operation progresses, and the larger and heavier becomes the roll of paper, the cord, u, will become also wound around the smaller convolutions of the snail-cone whereby the action of the weight, w, on the cord, working around the smaller part, will consequently exert lessening power to rotate the shaft, Z, and by such lessened force for rotation the draft action of the sprocket-chain, or chains, h, h, in the direction to press the winding-roll against the pressure-drum will be lessened in a ratio more or less nearly corresponding to the increased weight, and the correspondingly increased power for gravitation, of the made-up roll of paper.

In paper-winding machines embodying the features already described, in whole or in part, it is advantageous and desirable to lead the paper down to the winding-roll, from the Web, or supply, by having it guided over and around an overhead guide-roll, G, which is axially parallel with the winding-roll. This overhead guide-roll, G, may be supported by side uprights of the main framing, A, or by supports otherwise sustained.

In Fig. 5, in which a double winding machine is illustrated, side uprights, H, H, as aforementioned, are shown, on tops of which are constructed slide-ways, or ribs, :20, 00, for the journal-supports, y, for the guide-roll, G.

A screw, q, is supported in a suitable lug, 25, of each support, H, to operate upon the adjacent movable journal-support, y, so that minute adjustments of either, or both, of these supports for theends of the roll, may be acquired to compensate for any unevenness of the thickness of the paper, which latter sometimes runs, slightly thicker at, or near, one edge than at the other.

In Fig. 5, in which the duplex paper-winding machine is illustrated, having the characteristics substantially as hereinbefore described, in duplication, the paper is indicated as coming toward the guide-rollers, G, G, as of double width, the position of a slitter be- IIO ing indicated at 2, which severs the paper intermediately and longitudinally one-half running over one guide-roll, G, to the forward winding roll, while the other half runs over the other guide-roll to the rear winding-roll. As shown, the rolls, G, G, are at different heights so that the paper running to the forward roll may have no engagement with the rear guide-roll.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a paper-winding machine, the combination with the pressure drum, of a windingroll, opposite supports having parallel slideways, slides movable in said ways and supporting the journals for the winding-roll, and means for causing either one of the journals to have an independently adjusting movement whereby the axis of the winding-roll may, as purposed, be rendered slightly out of parallelism with the pressure-drum, substantially as and for the purpose set forth.
