MEANS ATTACHING BOIJLS OF PAPER TO SPINDLEB.

Application flled August 13, 1926. Serial No. 129,100. i

This invention relates to improved means for attaching rolls of aper to spindles and is particularly directe to an. improved device for quickly securing rolls ofxprint paper on spindles or shafts for use in cylinder presses, such as are used in newspaper .es

on a. spindle or shaft and then lift the spindle or shaft with the roll mounted there.

on and seat the shaft or spindle-ends in beatings on the press-frame so the roll and spindle may be revolvedas the paper is unwound and fed throughthe press.

Considerable difiicnlty is experienced at times in mountingthe rollson the spindles because it is a common practice to drive.

wedges betweenthe ends of the tubes-or cores and the spindles which is slow and unsatisfactory and frequently results in the roll being eccentrically mounted with the result that when unwinding intermittent jerks are given to the web and the latter tears, thus interrupting the printing operation until the web can be rethreaded through the press. i

In practice, two formsof tubes 01' cores are 1 employed in these paper rolls,.-one being 85 a heavy paper tube with metal ferrules on the ends thereof and the other being a metal tube. l i Our invention therefore has for its object to provide an improved device for quickly and accurately. securing the cores, either paper or metal, to spindles whereby the rolls may revolve evenly and without subjecting the webof paper. to the strains ,thathave heretofore caused thepaper to tear because of the eccentric revolution of the same.

The invention is illustrated in the accompanyin drawingswherein, u

thesame would upear if viewedon the line Referring to the drawin s the numeral 10, designates a paper :rollwiich is wound on a central tubulan core 11, which core may be of paper or metal. i

In the structure disclosed in Figs. .1 and 3 of the drawings, the tubular core 11 has a. metal .lcrrule 12 at each. of its ends for reinforcement purposes, and in so id. form the interior of each ferrule has a keyway or re-;

cess 13 therein asclearly shown in Fig. 3.

In the structure illustrated in Figs. 2 fund iof the drawing, the tubular core ispresumed to be formed of-metal 14, and the ends of. this metal tube are provided with notches 15. i

It is immaterialto our invention which of these cores is employed in the paper rolls as our structure is designed to coaet with either of theinin locking the core and the paper roll it carries to the spindle.

Our improveddevice, detached from the spindle and paper roll, is illustrated in Figs. 5 to 8 inclusive of the drawings to which particular attention directed.

Tlhestrmrturc includes a conicalbodv 16 whichcxtends laterally from a circular head 17 and both the/body and head being, providcd wit-ha circular opening or passage of a diameter to snugly receive the spindle or shaft 18. y

The smaller inner end 19 of the conical body 16 is of a smaller diameter than the interiordiameter of 'the corc-end12 of core or the end of, the core 14, whichever core happens to be in use, while the taper of the body is such that its circumference V Vlll wedge into the core-end, as shown in Figs. 1 and 2 of the drawings.

A key-slot 20 is formed in the head and conical body whielrslot extends through the head but is closed circumferentially at its outer end by the head but is open at both outer and inner circumferential sides of the conical body. The inner end of the slot is closed at 21 as best shown in Fig. 8 of the drawing.

A set bolt 22 is provided in the head 17 so as to extend therethrough and into the key-slot while anotherset-bolt 23 extends also through the head to the longitudinal passage.

A key 24 is provided which latter is designed to fit the slot 20 and is of sufficient length to extend through the head and to the rear end of said slot.

In the present instance the key 24 is rectangular in cross-section and is straight from end to end and when inserted in the slot 20, its inner or rear end will project outwardly from the slot or radially with respect to the axis of the conical bodv.

To mount aroll and its core on the spindle 18, the latter is passed through the core and a conical body 16 is inserted on each of the projecting ends of the spindle,- the smaller end 19 of the body is then entered in the core 11 or 14, and when doing this the body is turned so that the keyslot 20 therein will register with the recess 13 or the notch 15 in the end of the core.

The tapered body is then wedged or driven into the core-end sufiiciently to engage the same without slipping and this operation centers the spindle inthe core.

The keys 24, are then slipped into the key-slots 20 from the outer side and pushed inwardly through said heads until their inner ends enter the recesses 13 or notches 15 whereby to lock the bodies and the cores together. The set screws 22 may then be turned down through the heads so as to lock the keys in place while the set screws 23 may also be turned to lock the bodies to the spindles.

The structure is exceedingly simple and easily operated and will readily center the spindles in the cores.

The entire device,spindle, core and roll, is then lifted into place on the press and the web of paper from the roll fed through the press in the usual way.

Having described our claim,

1. In a device for securing the cores of paper rolls to spindles which cores have notches orkey-ways in their ends, the combination with a continuous one-piece conical body having a rigid head at the larger end thereof and provided with a central passage invention, we

therethrough of a diameter to fit the spindle on which it is to be mounted,said conical body havin a radial slot that extends all the way throng it from the central passage outwardly,-the inner end of said slot being closed adjacent to but spaced from the small end of the conical body and the outer deepest end of the slot register-i with a groove which extends horizontzi lly through the ri id head which groove is in communication with the central passage through the head-- a key extending from the outer side of'the head through the groove in the head into the radial but closed-end slot,-said key having its inner end'extending radially from the radial slot of the cone-body and entering the notches in the cores with the outermost fiat face of the key beneath the innermost wrap of thepaper on the core and means for securing the body to a spindle.

2. The combination with a paper roll having a tubular core which latter has a notch in the edge at each end thereof, of a spindle extending through the core and rojecting at each end thereof, a conical y having an enlarged head at the larger outerend thereof and a central passage therethrough which fits the spindle said conical body having a slot which opens radially from the inner side face of the enlarged head and which ex tends all the way through the conical. body from the spindle passage ontwardly,-the

head portion having a groove portion extending from its outer side face through said central passage in horizontal alinement with the said slot, a key extendinghhorizontally through the groove of the ead and pgojecting through the slot of the conical dy to the outer side of the latter whereby to enter the end notch in the core when the conical bod is entered into said eore'to lock: the conical body and core together and means extending through the enlarged head to-env gage the spindle to lock the conical body and spindle together. I

3. The combination with a roll of paper,

of a core extendingthrough the center of the roll, a spindle extending all the way through the core but of a lesser diameter than said core, two devices for'centering and locking the core and roll of paper on the spindle;- each of said devices comprising a bod having a continuous head at the outer si e and a conical portion at its inner side, the inner end of the conical portion being closed circumferentially but both the head and the conical portion being provided with a central passage that fits the spindle snugly,the conical portion having a longitudinal slot that extends from the circumferentially-closed end thereof to the head which slot opens 1,671,734 r i i 3 tion,-the cone-ends of the two devices be said inner ends of the keys engagin the ends ing entered in the ends of the core to center of the cores to lock the same to t e bodies the latter about the spindle, and ke s insertand the spindles. l0 able from the outer side ofthe hea through In testimony whereof we afiix our signa- 5 the key way in each head said keys having tures. their inner ends extending radially through i I THOMAS J OHANCEN. the slots of the co-portion of the bodies and EDWARD KEHOE.
