March 14, 1933- L. c. OKERBERG PRINTING PRESS ROLLER Filed June 23, 1931 md (5 ATTORNEY Patented Mar. 14, 1933 UNITED STATES LUTHER G. OKERBERG, OF, ELK CITY, OKLAHOMA PRINTING PRESS ROLLER Application filed June 23,

This invention relates to printing press rollers which will be an improvement over the conventional type of printing press roller now manufactured and sold in a form wherein the composition extends the full length of the roller and in one piece for an eight page edition, and to print an edition of a less number of pages the composition now being used is cut or otherwise removed from the roller causing a waste of material and expense, or the printers ink is allowed to flow or cover the unused portion of the composition which is a waste of ink and an expense and further causes considerable time on the part of the printer or operator to remove the accumulated ink from that portion of the roller whereby the time of the operator could be utilized for other work, and to obviate the above set forth disadvantages my invention is so constructed that a plurality of composition sections are provided, any number of which may be employed while the other sections may be easily and quickly removed from the roller and held ready for use .whenever desired.

Another object of this invention is the pro.- vision of means whereby the sections may be held against accidental relative movement and which will permit any one or number of sections to be removed and replaced on the roller as desired.

With these and other objects in view, this invention consists in certain novelfeatures of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure 1 is a side elevation illustrating a printing press roll-er constructed in accordance with my invention.

Figure 2 is a sectional view illustrating one of the sections removed from the roller.

Figure 3 is a similar view illustrating a companion section to that shown in Figure 2.

Figure 4: is an end view illustrating the roller.

Figure 5 is an end view illustrating one of 50 the securing collars.

1931. Serial No. 546,371.

Figure 6 is a sectional view illustrating the same.

Referring in detail to the drawing, the numeral 1 indicates a shaft of a printing press and has mounted thereon a plurality of metallic sections 2 coated with a suitable composition 3. The intermediate sections mounted on the shaft as shown in Figure 1 have their ends bevelled while the other sections have one of their ends bevelled to fit the intermediate sections and their other ends disposed straight to be engaged by securing collars 4 held in adjusted positions on the shaft 1 by set screws 5. Each collar has a bevelled edge 6 and a straight edge 7. The collars are capable of being reversed on the shaft 1 so as to present a straight edge for the section to engage or a bevelled edge when a section having a bevelled edge is disposed adjacent thereto. By having the sections so connected that they will be held against relative rotation as well as endwise movement relative to the shaft and permits any one or number of sections to be removed from the shaft when desired and the remaining sections then firmly r secured together and to the shafts by adjusting the collars on the shaft and relative to said sections.

The composition 3 of the sections provides the working surface for the paper to engage during the printing process and due to the mounting of the sections on the shaft permits the working surface in its entirety to be varied in accordance with the number of pages to an edition of a newspaper. Further the mounting of the sections on the shaft in the manner heretofore described permits the sections when removed from said shaft to be easily handled and packed for shipment. During the various seasons of the year, these sections must be returned to the manufacturers for the purpose of changing the composition to suit the climatic changes occurring during said seasons.

Further the sections being mounted on the shaft and capable of being removed one at a time permits this operation to be carried out by a single person wherein the conventional type of roller requires the eifort of two or more men in order to remove and replace the roller to the press.

Further the sections permit two color work to be easily carried out as the distance between the sections is enough to keep the colors from mixing or running together consequently obviating the fountain dividers now employed, for such purposes and which in themselves are costly apparatus.

While I have shown and described the pre-' ferred embodiment of my invention, it will be understood that minor changes in construction, combination and arrangement of parts may be made W1thout departing from the spirit and scope of my invention, as

claimed" .w

Having thus described my invention, what I claim 1s:

. A printing press roller comprising a plurality of cylindrical metallic sections removably mounted on a printing press shaft, composition material covering the sections, some of said sections having bevelled ends and the other sections each having one end bevelled and the other end straight, said sections arranged on the shaft with the bevelled ends in engagement and with the sections having straight ends located on the shaft with the straight ends next to the ends of the shaft,

and collars detachably secured to the shaft and having straight sides to engage the straight ends of the last named sections and having their opposite faces bevelled to engage the bevelled ends of the sections when thesections having the straight ends are removed from the shaft.

- In testimony whereof I aflix my signature.
