PAPER-REELING MACHINE.

To all whom it may concern.-

Be it known that I, ANTON SKoFsRUD, a

citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Paper-Reeling Machines, of which the following is a specification.

This invention relates to improvements in machines for winding paper from large rolls into small rolls or for making sheets of paper into rolls or tubes.

It consists in combining means for feeding and severing the paper, a novel spindle for winding the paper, and means for reciprocating the spindle, and in combining with these essential elements various details and features for the automatic operation of the machine, which will be described hereinafter.

In the drawings, Figure 1 is an end view of a machine embodying my invention. Fig. 2 is a side elevation with parts removed showing principally the winding and reciprocating mechanism. Fig. 3 is an elevation of the reeling end of the machine, showing the feed in g and cut-off or severing mechanism. Fig. at is the grooved cam-drum for reciprocating the spindle. Fig. 5 is a detail showing the cross-head pendent block. Fig. 6 is the clutch-operating mechanism. Fig. 7 is the tripping device for the clutch-lever. Figs. 8 and 9 are views of the spindle. Figs. 10 and 11 are enlarged details of the same. Figs. 12, 13, 14:, and 15 are details showing a modified form of spindle. Y

A is a suitable frame supported on legs a, provided with cross-braces a for supporting the shaft-bearings.

B is the main driving-shaft, divided at the clutch into sections 5 and 1).

b is the driving-pulley, mounted on the section b. A cam-drum O is also loosely mounted on this section, but is provided with a clutch-ring d, whereby it may be thrown into engagement with the shaft by the double clutch cone-sleeve D. Another clutchring d on the shaft-section b enables it to be thrown into engagement with the first section when the cone-sleeve D is thrown to the right, Fig. 2. A clutch-lever d pivoted at d and having av tripping mechanism at the top, is provided for operating the clutch.

On thesection b is fixed a pulley 12 with a belt running to a pulley e on a countershaft E, supported by brackets e at the rear of the frame. A second pulley e on this counter-shaft is belted to a pulleyfon an elongated sleeve-F, carried in bearings supported by brackets f in the center of the frame. A shaft G, passing through the sleeve, is provided with a spline registering with a keyway in the sleeve, so that the shaft will be rotated therewith, but maybe reciprocated therein. The shaft may rotate freely in a cross-head g at the end thereof, but is prevented from lateral movement therein by the collars g The cross-head slides in suitable ways a on the frame A, and an elongated pointed block G, (shown in Fig. 5,) pivoted to the lower side of the cross-head, is adapted to engage with grooves c in. the doublegrooved cam-drum (J. The method of double-grooving the drum is shown in Fig. 4. It is done in this manner to obviate the use of a drum of too large diameter, and in order to prevent the cross-head-drivin g device, which might otherwise be a roller, from taking the wrong groove at the point 0 Where they cross it is made elongated and pointed, as shown. By making it in this shape it takes the curves at the end of the drum and alines itself on the longitudinal courses, so that it readily passes over the opening made by the intersecting groove. The cross-head also carries a plunger for operating the clutch-lever,

which will be more fully described hereinafter.

Attached to the end of the shaft G is the winding-spindle H. (Shown in Figs. 8, 9,10, and 11.) A threaded socket 7t is screwed into the shaft, and a tube It is firmly fastened therein, or the tube may be made integral with the socket. A shaft I of irregular cross-section is loosely fitted in the tube.

rigidly inserted in the end of the shaft I and passing out through a transverse slot 7L in the socket h and a diagonal slot 77, in a sleeve 7L fitting over the socket-piece and slidingly keyed thereon. A spring 71 pressing against the shaft G and the sleeve 7L5, holds the sleeve in its normal forward position,in which position the barbs are retracted. The spindle passes through a bearing in a bracket a 0n the frame, which engages with the sleeve h and stops it slightly before the spindle has traversed to its forward position, thereby throwing the pin over and projecting the barbs. \Vhen they are thus projected and the paper is fed, by means which will be presently explained, the forward edge of the paper will be pierced or engaged by the barbs and the roll started. \Vhen it is completed, the spindle is stopped, and as it is withdrawn the forward face of the bearing (1. forms a stripper to strip off the completed roll from the spindle, which is readily done, as the barbs are immediately retracted by the spring when the spindle starts back.

A guide and smoothing roller J is supported byits gudgeons j in spring-pressed sliding bearings 3', supported in brackets J, overhanging from the rear of the frame A. This roller will normally rest on the spindle as it is advanced and will be raised up as the roll is formed. A barj connects the bearings j and raises or lowers with them. A tilting feed-table K, Fig. 1, is pivoted at 7a in slotted brackets K and is provided at its forward edge with rods attached to lugs on the sliding bearings j. Normally the edge of the table registers approximately with the top of the spindle, but as the roll increases the edge is raised by the rods to conform thereto.

The paper is fed by a feeding roller L, and a spring-pressed idler-roller L coacting therewith. These are carried in a bracket L attached to the front of the frame, which also supports the severing device. Attached to the projecting gudgeon Z is a disk Z. (See Fig. 3..) A friction-wheel M is adapted to engage therewith and with a second disk N. This wheel is suspended by a rod m from a lever m, pivoted to a rigid brace m attached to one of the brackets J. The other end of thelever is connected by a rod m to the crossbarj before mentioned, and as the bar rises the friction-wheel is correspondingly lowered. The disk N is carried on the end of a countershaft n, mounted in brackets 72, attached to the frame, and is held normally against the wheel M by a spring 72 around the shaft, which has suflicient lateral motion to allow the release of the wheel. This shaftis driven by a belt running from a pulley n thereon to a pulleyf on the sleeve F. At about the time the spindle is projected across the feed- Way the cross-head striking a rod N pushes it forward and throws a lever N which presses back the shaft 'n and releases the friction-wheel M, allowing it to rise as the roller oted at s to a brace from the cross-head.

J drops. (See Figs. 1 and 2.) It is readily seen that this mechanism gives a variablespeed feed,dependent upon the increasing size of the forming roll.

The cut-olf mechanism consists of a knife 0, supported on rods 0, which pass through bearings in the brackets L and hold the knife raised by the springs 0. These rods are connected at the lower ends by a bar 0 A tappet-arm 1) on a rod P, supported in the brackets 12, is adapted to engage the bar 0 when desired and bydepressing it cause the knife to sever the paper. This is accomplished by means of an arm 13 on the rod I, which engages with a pin p on a disk 19 when it is rotated The disk is carried on a short shaft 19, mounted in the brackets 1), and carries at its opposite end a ratchetwheelp". An arm p looselymounted on the shaft, carries a pawl 12", adapted to engage with the ratchet-wheel. The arm isoscillated by a rod 19 Fig. 1, attached thereto and extending back across the bed to connect with a disk 6 on the end of the shaft E, Fig. 2. The disk is slotted to allow the connection to be made adjustable toward or away from the center to decrease or increase the throw, and consequently the number of revolutions, of the shaft necessary to cause a complete turn of the shaft 19 with its diskp.

It is desirable to stop the entire feeding and winding mechanism when the spindle is being retracted and projected across the feedway, and to this end the tripping mechanism before mentioned on the clutch-lever (Z and means for operating it are provided, as.

shown in Figs. 3 and 6. The clutch is held in normal engagement with the drum by means of a link 1*, attached to the top of the lever (Z and connecting with a lever B, pivoted at r to the frame and having a spring r at the opposite end extending forward to a convenient attachment on the frame. YVhen the spindle has reached its forward position, a rod S, fixed in the cross-head, strikes the lever d and carries the plunger D forward to cause the sections of the shaft to revolve together, and consequently start the revolving and feeding mechanism. In order that the throwing of the lever may be accurately timed, the rod S is attached to a lever s, piv- A spring S from the lever to the cross-head keeps the rod normally projected. As the cross-head advances the lever strikes a pivoted stop S on the side of the frame, and the further advancement causes the lever to swing back, the spring stretched, and the rod S drawn back from its normal operative position. An arm 5 on the stop is attached to a rod 5 extending back to an arm 8 of a bent lever S having its forward arm bent down to engage with an adjustable pin 3 on the end of the drum 0. A spring S attached to the arm 3 and the frame, holds the levers and catch in a normal position for engaging the lever .9. When the cross-head ceases has advanced to the position desired for the clutch to be thrown, the pin 8 striking the bent end of the lever S swings it back and through the rod and catch S releases the lever 8, when the springs S throws the rod S forward against the lever d and overcoming the spring r forces the clutch-lever d forward. In order that the clutch may again be thrown into engagement with the drum at any desired time, the end of the lever (1 Fig. '7, is provided with a catch d pivoted at 01 with which the rod S engages. 'A spring (1 holds the catch in a normal upright position. One arm d of the catch engages with a notch in a lever T, pivoted at t,

which prevents the catch from being thrown over when the rod S strikes it. One arm 25' of the lever T extends forward to engage with a tappet-arm t on the rod P. The tappetarm striking the arm 25 and raising it, releases the catch and allows the spring 1" to again throw the lever d back.

The operation of the machine as a whole is as follows: The power being applied to the driving-pulley and the drum being clutched in, the cross-head, shaft, and spindle are driven forward until the spindle is across the feedway and the barbs thrust out. Immediately the clutch is thrown over, the drum stopped, and the winding mechanism started, when the tube or roll is completed, the tappet-shaft is thrown, the clutch released, and the paper severed. The drum being thus thrown in again, the spindle is retracted, the tube stripped off, and the machine is ready to repeat the operation.

In the modified form of spindle shown in Figs. 12, 13, 14, and 15 the barbs are to be thrown out by the longitudinal movement of a shaft in place of a rotary one. The barbs a; are at the ends of cam-shaped members X pivoted at at to a stationary strip in the tube. A sliding split-shaft member Y is provided with cam-grooves y, engaging with the members X. A backward movement of this strip projects the barbs and a forward one retracts them. This is accomplished by a pin g extending through a slot 'y to engage with the sleeve k Having thus described my invention, which I am well aware may be easily changed in various details and in which I do not limit myself to the exact construction shown, I claim- 1.
