Specification of Letters Patent. l Ptente July 25, 1916.

Application filed February'21, 1914. Serial No. 820,166.

To all whom t may concern:

Be it known that I, FRANK H. HoBERG, a citizen of the United States, residing at Green Bay, county of Brown, and State of "Wisconsin, have invented new and useful Improvements in finding-Rollers, of which the following is a specification.

My invention relates to improvements in winding rollers for the cores of rolled paper packages.

The object of my invention is to provide means whereby a series of paper package cores may be mounted upon a single elongated roller and securely bound thereon for rotation with, ythe Aroller during a paper winding operation, the cores being subsequently released for free withdrawal from the winding roller in a longitudinal direction. f

In the drawings-'Figure l is 'a side vie partially in longitudinal section of fragments of a winding roller embodying my invention, showing a series of paper cores thereon in position for the paper winding operation. Fig. 2 is a cross Sectional view of the same, drawn on line :l2- zc of Fig. 1.

Like parts are identified by the same reference characters in both views.

My improved roller comprises ahollow cylinder A provided with a series of internal spider brackets B, in which one or more longitudinally extending rods C are journaled, these rods being provided with conical expanders D at suitable'intervals. The cylinder wall A is apertured on opposite sides of each conical expander D and an interiorly projecting plug or boss E is secured in each one of these apertures. Each of interior surface of'a paste'board corejon the roller, thereby locking saidcore against in"` 'dependent rotation and causing the same to rotate with the roller. v l

eoA

It win be Observed that the expander D is' provided with an abruptlytapered .portion d at its smaller end and a slightly taperedv portion d at its larger end,so that saidlex pander will tend to remainin Apinholling posltipn whendrawn between the. heads of the pms F. A coiled springH may be interposed between anyone of .the `bearing, brackets B and a cross pin l1. on the rod C,'

said spring tending to retract the rod after 1t has been pushedto expanded position.

It may, however, be held against retraction by a locking cam .I pivoted to the end or head of the roller. ,A

It it not necessary that locking .pins F and expanders D be employed for all of the paste board cores which'the Winding roller v is adapted to receive. It will be suiiicient if the end cores are' thus locked to the windingv roller, since the intermediate cores may be held by frictional contact end to end with the end cores. It will be understood that after the cores are slipped on to the Winding .roller with the pins in-retracted position,

these plugs is provided with an interior.

socket ey in whicha headed pin F is seated. The pin F projects outwardly through a hole in the plug E and is adapted to be projected radially beyond the periphery of the cylinder. A spring G is coiled around the pin F within the'socket e, this spring tending to retract the pin from its radially pro'- jec'ting position. These pins are located in pairs on opposite sides of the expander D, and when the larger portion of the expander D is moved between the heads f of the pins, said pins are forced outwardly against the tension of the retracting pins G. A set of these ins F projects through the peripheral wall of the roller at proper intervals, so that the pins of each such set will, when projected radially, bear forcibly against the rod C will be pushed inwardly, or if one rod is used near each end of the winding rollers, both of theseA rods may be pushed inwardly to force the expanders between the heads of the pins and Inovethe pins outward radiallyto lock some of the cores at least by direct pressure of these pins against them.

The' ends of the winding roller may be provided with suitable journals J and one end portipn is `preferably squared as illustrated at K, so that it is adapted to fit into a squared socket or opening in a driving gear wheel or pulley. After the paper has been wound upon'the cores to form a series of roller packages, the winding roller may be withdrawn bodily from'the winding machine and from the driving gear Wheel, and` all the rolls of paper carried thereon to any suitable delivery point, whereupon the rod C will be released by an appropriate adjustment of the cams I, the rods thusmoving outwardly, drawing the expanders awayy from the heads ofthe pins and the pins being thereupon retracted by their individual retracting springs G. The rolls of paper with their cores will then slip loosely from the winding'roller.

I claim-- l l. A winding roller adapted to receive sets of paper package cores, in end to end relation, comprising a tubular core receiving member adapted to receive and support a plurality of cores in end to end adjustment, plural sets of blunt ended pins radially socketed therein and adapted to be projected through its periphery, the pins of each set being adapted to engage one of said cores, and means for actuating said pins into and out of frictional pressure contact with package cores through which said roller passes,`

2. A winding roller for sets of paper package cores, comprising a cylindrical member, a plurality of sets of blunt ended coreengaging pins radially socketed in said cylinder and adapted to be projected through its periphery at different points along its surface, and means for projecting said Vpins through the cylinder Wall into positions to engage a plurality of package cores through Which said roller passes, said actuating means comprising a longitudinally movable rod within the roller, tapered.

pin actuating expanders on said rod, and retracting springs operatively connected with said pins.

3;'A-winding roller for'sets of--paper package corescomprisinga cylindrical member provided with a series of apertures, socket members each having screw threaded engagement with the wall of one of said apertures and projecting inwardly, pins each enlarged at its inner end and seated in the respective socket members with their r outer ends projecting through the socket members to the exterior' of said cylindrical ward radially in opposition to the pressure of said springs, said pins having'blunt outer ends adapted to frictionally engage cylin drical tapered cores mounted on said cylindrical member, substantially as described.

n testimony whereof I allix my signature in the presence of two witnesses.
