ROLL-HOLDER FOR PRINTING-PRESSES.

Specification of Letters Patent.

- Patented July as, 190s.

To all whom 'it may concern:

Be it known that I, HANS P. HUSBY, 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 Roll-Holders for Printing- Presses, of which the following is a specification, reference beinghad to the accompanying drawings.

My invention relates to roll-holders for holding a roll or web of paper as commonly used in perfecting presses, and it has for its .object to provide a new and. improved rollholder by which the roll may be quickly and iirml secured upon the shaft or mandrel by whic it is supported while on the press; also to provide a construction by which the rollholder may readily accommodate itself to diameters. f I accomplish these objects as illustrated lin the drawings and as hereinafter described; i

That which I believe to be new is set forth in the claims.

In the accompanying drawings,-Figure 1 is a sectional view of a roll, showing my improved roll-holder; 2 is a partial longitudinal'section ofthe roll-holder; Fig. 3 is a v similar view, showing the parts in locking position; Fig. 4 is a cross-section on line 4--4` of Fig. 2; Fig. 5 is a perspective view of a part of the clamping,mechanism; Fig. 6 is a perspective view of one of the blocks by which the shaft is'clamped; Fig. 7 is a perspective view of one .of "the rocking levers which eng-age the clamping blocks; and Fig. 8 is a sectional view, showing a modification.

As is well understood in the art, and as illustrated in Fig. 1, a web of paper is usually wound in a roll upon a hollow tube or core,-- 10 indicating the web and 11 the core.

l2 indicates the usual shaft or mandrel, which in practice is passed through the tube 11 and is tted in suitable bearings on the pressso that the web may unwind freely as the paper is consumed.

13 indicates a normally stationary head, which is secured upon one end portion of the shaft 12, preferably by a set-screw 14, so that vide `ried by a frame or support 26 which iits upon 4.

conical portion 15 of the head 13,-the ar- A rangementJ being such that by movin vthe head 16 toward the head 13 theroll tu e 11 may be wedged-tightly between said blocks. The head 16 is provided with/a sleeve 18, the inner portion of which is externally screwthreaded, as shown-at 19 in Figs. 3 and 5,- the outer-end portion being provided lwith longitudinal slots or recesses 20 at suitable intervals, as shown lin Fig. 5. Said slots are open at their outer ends to permit of the parts being assembled.

Itl will be understood that the sleeve 18 iits loosely upon the shaft 12 so that it may be rotated or moved longitudinally there-v with a' upon. Said sleeve.is also provide shorter slot 21 closed at its ends for a purpose which will hereinafter appear.

22 indicates a series of clamping blocks or keys, theinner faces of which are corrugated, as shown at 23 in Fig. 6, and which are adapted to iit in the slots 20 in the sleeve 18. By pressing the blocks 22 inward against the shaft 12 they may be caused to bite the same with sufficient force to prevent the rotation or longitudinal movement of the sleeve 18 u on the shaft. For actuating the clam ing b ocks 22 rocking levers 2 4 are pro- Which are mounted on pivots'25 carthe sleeve 18, as shcwnin Figs. 2,v 3, an In the principal iigures I have shown the support 26 as being arranged'to support vfour levers 24,-the sleeve in this case eing proyided with four slots 20, with a corresponding number of clamping blocks22. In Fig. 8 I have shown'a correspondingframe 26, designed to accommodate three of said levers 24, the arts being in other respects the same. (l) levers and clamping blocks may be employed.1

'lhe levers 24 are bell-crank levers, each having an inwardly-projecting arm 27 which iits in a suitable recess in the adjacent clamping block 22, as shown in Fig. 3*thus not y insuring the proper engagement vbetween said arm and the clamping block but also providing for moving the clampin blocks longitudinally of the shaft 12' with bviou'sly, any desired' number ofv .A said levers when desired.- The levers 24 are also provided with horizontally-extending arms 28, which project over a Wed e-block 29 mounted upon the screw-threa ed por--4 tion ofthe sleeve 18, as shown in Figs. 2 and 3. Itwill be observed that the wedge-block 29 li'es between the head '16 and the levers 24,

, so that by rotating saidwedge-block upon 18-16, and as said heads are locked to the,

' shaft 12 the roll is also secured to said shaft.

By rotating the wedge-block 29 in the oppo site direction, the shaft- 12 is released and the clamping mechanism may be readil moved longitudinally thereof to at once re ease the roll. To prevent excessive movement of the frame 26 upon the sleeve 18 I rovide a setscrew 30 which passes throug said frame and into the slot 21 in said sleeve, as shown in Figs. 3 and 4; The screw 30 is removed when the parts are to be taken apart.

have thus provided a clamp which is readily adjustable to engage or disengage the roll,

and which may accommodate itself to roll tubes of diiferent'lengths or diameters; also one which may readily be removed from the shaft without being disassembled, and which may be locked to the shaft at any point that may be necessary to accommodate the roll prisin mounted thereon. Y

While I have described in detail the embodiment of my invention illustrated in the accompanyingdrawings, I wish it to be understood that my.invention is not restricted to the details of the constructiondescribed, except in so far as they are specifically claimed, but includes generically the subjectmatter of the broader claims.
