' INK-FEEDINGROLLERT Application filed May '22, i923. Serial a... 640,762? j To-all whom itflmagj commv Be it known that I, CHARLES CUGARNER,

a citizen of the United States, residing at Govington, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in: Ink-Feeding Rollers, of which the following is a specification. a i 1 My invention relates to improvements in inkfeeding rollers for printing presses of the type which areparticularlywell adapt ed for double width newspaper presses,

while not necessarily restricted to this use.

In operating these double width newspaper presses different sizes of papenare used at difl'erenttimes, which necessitates the useof a different 'ink'feeding roller for every'size'of papertobe used The object of my inventioni'isjto construct 0 a roller-which may bereadily adapted for use with any of the different sizes offpaper now inuse on these printing presses. 7

Another object of the invention is the pro vision with adevice of this character of a novel securing means for the sleeves or bushings.

Another object of the invention is to provide a device of the character which is characterized by simplicity of operation and construction and which will be strong and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings which form a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of my improved roller, parts being in section and other parts being broken away,

Figure 2 is a top plan view of my device as it is when used with a reduced size of paper,

lgigure 3 is an end elevation of Figure 1, an a Figure 4 is a transverse section taken on line 4-4: of Figure 1.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention, the numeral 10 designates the roller stock which is of the same width as the widest size of paper used on the press and which has reduced extensions 11 formed on each of its ends. These reducedextensions carry journals 12 which fit in the usual bearings of the press. f

The stock [10 isfprovided with a longitudinal keyway 13,whic h'ext'endsthrougk out its entire length. Sleeve sections *14" and 15 are slidably mounted on the stock 10 and have longitudinal keys 16 which are ofthe same size and shape as the keyway 13' and are adapted to snugly fit therein. The sleeve section ltg'is arranged in the center of the stock 10jand is of a size to correspond with the sma llestfsize of paper used on these types of presses; this sizebeing considerably larger than the size of the smaller end sleeve sections 15, These sleeve sections are cov- '70 ered witha layer composition 17 of the kind usually used on these rollersand" this layer of'compositionextends to the ends ofthe smaller end sections and hasitsouter edge bevelled as at 13. The composition layer '75 iscut at the pointsof the sleeve sections and these sections ar thereforeFseparate and distinct.* I

' Clamping blocks were arranged one at each end of the stock 10 and to one side of 80 the keyway 13. Each of these blockshas a longitudinally extending slot 20 for the reception of a bolt or screw 21. This block is arranged with one end engaging the end of the stock 10 and its lower face resting on the reduced extension 11. The screw 21 is screwed into the end of the stock 10 and the sleeve sections will be securely held in place. These blocks are of a height so as to reach from the reduced extensions to the top surface of the sleeve sections and are the same width as the keyway.

In operation, when only the center sleeve 14 is being used, the clamping blocks 19 are arranged in the keyway 13 and to each side of the sleeve. The screws or bolts 21 are screwed into the openings 22 and the sleeve is clamped in place. If one of the end sections is used together with the center section, then one of the blocks is ar ranged on the reduced extension 11 and the other is arranged in the keyway. As the slots 20 are considerably wider than the screws 21, the blocks are capable ofadjustment besides that afforded by the series of openings 22. These slots also allow adjustment without removing the screws from the openin s.

It W111 therefore be seenthat I have provided a very simple and efiicient device is always in use and When a half size roller is wanted, the two small end rollers may be ,used in place of the large center one, and

thus it is possible to keep the roller a uniform size.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of my invention, or the scope of the subjoined claims.

Having thus described my invention, I claim:

1. In a device of the character described, a roller stock having a longitudinal keyway extending throughout its length, sleeve sections adapted to be removably mounted upon the stock and having longitudinal keys to engage the keyway in the stock, and clamping blocks of the same width as the keyway, said clamping blocks being normally arranged on the end of the roller stock but capable of being arranged within the keyway When any. of the sleeve sec-- tions are removed.

2. In an ink feeding roller, a roller stock having a longitudinal keyway extending throughout its length, journals carried by the roller stock, sleeve sections removably mounted on the roller stock and having keys to engage the keyway in the roller stock, said sleeve sections having a layer of composition on their surfaces, locking blocks to lock the sleeves on the stock, said looking blocks being of the same Width as the keyway in the roller stock and being adapted to be located either at the ends of the roller stock or Within the keyway, and means carried by the locking blocks for independently adjusting said blocks.

3. In a device of the character described, a roller stock having a longitudinal keyway extending throughout its entire length, reduced extensions carried by the roller stock at each of its ends, fiiournals carried by the reduced extensions, sleeve sections removably mounted on the roller stock and having longitudinal keys to engage the keyway in the roller stock, and locking blocks adapted to rest on the reduced extensions and to be clamped to the end of the roller stock so as to retain the sleeve sections onthe stock, said locking blocks being of the same width as the key.wa.y and capable of be ing located within the keyway when any of the sleeve sections are removed, said blocks also having slots to receive clamping screws, the slots being of a size to allow the blocks to be shifted for adjustment, with the screws in position.

In testimony whereof I aflix my signature.

CHARLES C. GARNER.
