Specification of Letters Patent.

Patented Dec. 20, 1910.

Application filed March 2, 1909. Serial No. 480,953.

T 0 all whom it may concern:

Be it known that I. JomvJ. VARREN. a citizen of the United States. residing at Brownville, county of Jefferson. and State of New York, have invented certain new and useful Improvements in \Vinding-Machines; and I do hereby declare the following to be a full. clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to machines for wind ing paper. It is designed for use in connection with paper making machines which form the sheet in a continuous length and supply it to the winding machine, which thereupon reduces it to compactly wound rolls of appropriate sizes for commercial use.

The invention relates particularly to paperwinding machines of the type known as doubledrum winders. wherein two winding drums of unequal size operate a displaceablecore upon which the paper is wound into a roll as it is received from the paper making machine. In these double drum winders, the smaller drum is driven at a relatively higher rate of speed than the larger drum, for the purpose of effecting the uniform, compact and smooth winding of the roll of paper.

The purpose of my present invention is to simplify and cheapen the cost of product and the maintenance and repair of machines of this general character, to make certain parts of the apparatus more positive and reliable in their operation and togreatly broaden the scope and usefulnessof paperwinding machines of this general type.

The construction and mode of operation of the machine will be hereinafter fully described and the features of novelty will be set forth in the claims.

Referring to the drawings, Figure 1 represents, in side elevation, the preferred form of my improved paper-winding machine;

Fig. 2 represents a side elevation thereof, broken away centrally so as to permit its illustration on a correspondingly large scale, and being likewise shown partly in section; Fig. 3 represents, partly in section and partly in side elevation, certain of the main elements of the machine,particularly the means for suspending the journal boxes for the core shaft of the roll to be formed; Fig. 4 represents a sectional plan view taken on a plane indicated by the line t4 of Fig. 3;

Fig. 5. represents,partl-y in section and partly ln side elevation, a part of the meansfor raising the roll of paper and its core, under certain circumstances; Figs. 6 and 7 repreguiding the journal boxes of the core shaft 7 in the machine shown in Figs. 6 and 7; Fig. 9 represents a sectional plan view taken on a plane indicated by the line 9-9 of Fig. 8; Fig. 10 represents a longitudinal sectional view, showing the way in which the backing ratchet of my invention may conveniently be coordinated with a sprocket wheel drive; Fig. 11 represents a face View of the backing ratchet proper; Figs. 12 and 13 represent respectively, in end elevation, the main elements of modified forms of my invention; Fig. 14 represents a detail View thereof; Fig. 15 represents a detail view of the links for automatically actuating the safety guard.

Referring to the drawings and particula rly to the form of the invention illustrated in Figs. 1 and 5 thereof, A represents stout castings, constituting the bed plates of the machine, upon which are mounted the end standards B having overhanging upper portions as shown, the said bed plates A and standards B constituting the frame work of the machine and supporting the journal bearings of the several machine shafts. The smaller drum D of the winder is driven at ahigher rate of speed than the larger drum C, for the purpose of effecting the uniform, compact and smooth winding of the roll of paper. The shaft of the smaller drum D is driven by means of a belt (not shown) from the shaft of the larger drum C, and the peripheries of both drums are preferably provided with spirally shaped grooves or recesses, formed or cut therein to prevent the paper from becoming crimped during the winding operation and for straightening it out so that it will wind smoothly and evenly as the roll is being formed. The spiral grooves are the same as those shown in Letters Patent No. 798,241, granted to me August 29, 1905, and are for the same purpose. So also, the smaller drum is preferably provided with a semi-cylindrical guard E mounted to rock upon the shaft of the drum D, and connected by an arm a,

and by links 5, 6', b 6 with one of the journal boxes F in which is mounted the displaceable core shaft 0 for the roll of paper. The function of this rocking guard is to protect the operator from being caught between the roll of paper and the drum D, and, indeed, to prevent the accidental entry of any object between the forming roll of paper and the drum D; the upper free edge of the guard is automatically kept at a preferred distance from the circumference of the roll of paper. regardless of the increase in diameter of said roll of paper. In order that the movement may be more rapid up to the time when the roll attains a diameter of say eight inches, the two links b are slotted, as shown, and the arm a has a projection a which passes through the slots as shown in Fig. 15) and which bears against the upper end of a spring a surrounding a guide rod a supported below by the fixed pin a and passing freely through an aperture in the end of the projection a.

A characteristic feature of my present invention consists in the fact that the journal boxes or bearings F, in the preferred form of my invention, are suspended freely, by means of rack bars (Z, from pinions c with which said rack bars mesh. The rack bars pass through the slotted guards f, 5 located respectively above and below the shaft G upon which the pinions c are mounted; with the resultant effect that the rack bars, while having a capacity to swing freely to the extent required by the change in position of the core shaft 0 as the roll of paper increases in size. are nevertheless guided in their movements by the slotted guides referred to, thereby limiting the swing of the rack bars and particularly relieving them from strain due to any incidental crowding of the roll of paper upon the journal boxes due to possible lack of absolute uniformity in the building up of the roll of paper.

'l dler rollers it keep the ack bars (Z in mesh with the gears c, and lessen the friction of the parts. The shaft G, upon which the gears e are fixed, has likewise splined or otherwise fixed upon it the backing ratchet 17, which is adapted to cooperate with a corresponding spring-pressed driving pawl j mounted in the hub of a gear H which is mounted idly upon the shaft G and is restrained from longitudinal movement thereon by the collar k. The gear H meshes with a pinion I fixed upon a shaft Z having a hand wheel J and likewise having a ratchet m cooperating with a pivoted holding pawl 12,-

having a releasing handle 7). Itwill be apparent, from this construction, that, as the core shaft 0 rises with the increase in size of the roll of paper, carrying with it the ournal boxes F. the racks (Z are llkewise free to r1se, revolving the gears e and with then the shaft G; whereas gear H is permitted by the backing ratchet 'a' and its pawl j, to remain stationary, being locked or held in position by the locking pawl n engaging with the ratchet m, to which the idle pinion H is geared. It is also an incident to this construction that by means of the hand wheel K mounted upon the shaft G, the journal boxes F and core shaft may, if desired, be conveniently raised when there is no conside able load of paner on the core shaft, and also that the said hand wheel K may be made available as a temporarv means of pressing down on the said core shaft, which is sometimes desirable, for a few seconds, when starting the formation of a roll of paper thereon. It will be further understood that the function of the hand wheel J with its ratchet 1/2 and holding pawl 22, is to raise the roll of paper for making a splice, or for removing the roll, or for any other like purpose, the holding pawl 11 serving to prevent the descent of the racks and their journal boxes from the position to which they have been raised, and the power for raising them being appropriately multiplied bv the relative size of the pinion I and gear H. In some instances, if the paper fed from the calender rolls to the winding machine is calendered thin on one side (as, for example, on the right hand side as viewed from the front of the machine) it is desirable to correspondingly raise the right hand side of the winder shaft 0 so that it may carry its appropriate part of the weight of the paper and to prevent it from giving to the forming roll of paper a smaller diameter at the right hand side than at the left hand side; or, instead of positively raising the right hand side of the winder shaft 0, in such case, the same effect can be produced by lowering the left hand side thereof. This change in level or inclination of the winder shaft 0, I effect by making the connection between the 'ack bar (Z on the side of the machine where the operator stands and the journal box F adjust-- able. This is preferably effected by means of hand operated gearing, as. for instance, by providing the lower end of the rack bar (I (as shown in Fig. 3) with a screw-threaded portion (1 -arrying a nut I which nut meshes with a worm r mounted upon a shaft which carries the hand wheel .9.

It will be understood that the continuous length or sheet of paper as it comes from the calender rolls, passes over the spreader and beneath the larger drum C and thence is mounted upon the core shaft c. The roll of paper as it forms upon the core shaft 0 is indicated in dotted lines in Fig. 1 by the letter u and in full lines in Fig. 4 by the same letter. In front of the smaller drum D are located the stands or brackets N, which are provided for the purpose of re ceiving or supporting the core shaft 0 either of the journal boxes with a projecting arm before or after the paper is wound thereon. The journal boxes F, as shown, are provided l with a hinged upper portion '0 which may be held in the elosedposition by the spring I catch (1:, thereby providing means for read ily inserting and removing the core shaftx.

In the modified form of the invention shown in Figs. (3-11, the main features of construction are the same as those already described and are correspondingly indicated by like reference letters. In this instance, however, the rack bars (Z occupy a position closer to the gear H, and the pinions c on the shaft G with which the racks inter-mesh are centrally located. This arrangement permits the employment of hinged guide posts S depending from the overhanging standards" B and passing through corresponding openings 8 in the journal boxes F. The lower ends of these hinged guide posts b pass through corresponding slots in the bed plates A and the bed plates are provided with adjustable pieces t for appropriately limiting theswing of the hinged guide posts, which, nevertheless, have a sufficiently free lateral movement to :permit the journal boxes F to shift their position automatically so that the forming roll, of paper it may always rest upon the drums C, D, irrespective of any imperfection in the core or winding shaft. In order to protect the journal boxes F from any twisting or outward movement which might be caused by the crowding of the paper, Inlay, in this form ofmy invention, provide either or both an engaging at its free end in the vertical guide slot or way of a guide track 3 bolted to the upright B,

In Fig. 1.0, which likewise illustrates the gei'ieral arrangement of the parts constituting the backing ratchet connection between the gear H and the shaft G in the form of the invention shown in Figs. 6-9, I have substituted a sprocket gear 6 for the pinion same arrangement may be employed in connection with the sprocket chain shown in my Patent No. 798,241, hereinbefore referred to. p

In the modification indicated in Fig. 12, I have shown the rack (Z as guided at its lower end iiia slot of the bed plate A. In Fig. 13, I have shown the rack 01 as provided further with an auxiliary hinged guide stem S, which, passing through the journal box F, as in the modification shown in Figs. 69, likewise passes through an adjustable guide slot in the bed plate A. In

both of these modifications, the journal box adjacent to the operator may be provided, as in the preceding modifications, with means for raising or lowering it, so as to level the core shaft 0, for the purposes hereinbefore -set forth. This may beconveniently effected, as shown, in Figs. 12-14, by providing the rack with an internally screwthreaded nut 2, through which passes a.

screw shaft 0 supported in fixed hearings in the journal box and provided with suitable means for rotating it, as, for instance, the

hand wheel 8, so that, by actuating the hand wheel, the position of-the journal box may be appropriately raised or lowered to obtain the inclination desired for the core shaft c.

'hile, for the purpose of more fully disclosing and elaborating the scope of my invention, I have shown the modifications illustrated in Figs. 6-11, I nevertheless prefer, as hereiiibefore indicated, the construction shown in Figs. 1-5, as presenting the greater simplicity and economy in point of construction and maintenance; more especially since it enables me to dispense wit-h the hinged guide posts and whatever expense and inconvenience are connected with their use.
