Serial no.4sa'a'z'a- This invention is a novel iinprovementin printing presses, and is especially adapted for use as afudge attachment for printing presses for printing late news, but it is also adapted for use in many types of printing presses where hit-and skip printing may sometimes bedesired on alternate. sheets or where a divided cylinderwould be useful.

An essential feature of my present inven- 110 tion is a divided impressioncylinder, each part of which has a semi 'cylindrical impression surface, and such parts can be adjusted toward each other to constitute a complete cylinder two-pages around adapted to print two pages like an ordinary rotary press cylinder; or the parts may be separated so that only one of them will be in operative posltion and consequently will only print every alternate sheet during the rotation of the cylinder, every other sheet being skipped;

In the accompanying drawings I have illustrated one practical embodiment of the invention as utilized in a fudge printing attachment for web printing presses, but an explanation and understanding thereof will enable others toadopt and use the invention not only for fudge printing, but in other places in the printing art where hit and skip printing or a divided cylinder may be desir- 30 able. In the claims following the description I have set forth the essentials of the invention and the novel features of construction and novel combinations of parts for which protection is desired.

In said drawings:

ing mechanism embodying my invention, the parts of; the divided cylinder being shown adjusted so as to print every successive sheet. F 2 is an enlarged longitudinal section through the novel cylinder the parts thereof being adjusted so that theyboth will act upon the web like an ordinary sized two-pageround impression cylinden;

Fig.3 is an end view of the novel cylinder showing thelpositions of the blanket and reel rod of each part; v Fig. 4 is a view similar to Fig. 1 showing the parts of theq'cylinder arranged so that only every other sheet'willbe printed, as on Fig. 1 is atop plan View of afudge printthe hit and skip plan which is necessary 7 when the sheets are being collected. I Fig. 5 is a section'on the line 5.5 Fig. 4.

Referring to Figs. 2 and 3; land Zdesignate the similar complemental parts or halves of an impression cylinder. The part lhas a body portion 1a which is about half the length of the cylinder and is splined upon a supporting shaft 3 sothat it can be adjustable longitudinally on its shaft. One half of the body portion is of less diameter than the cylinder proper. The opposite half is of the full diameter of an ordinary impression cylinder and has a longitudinally extending portion 16 at one end. The half 1?) of the part 1 is-a full page in area and is substantially twice as long as the body 1a. The body 1a is cored out as at 10 at the side adjacent the part 1?) (see Figs. 2 and 5) in order to practically counterbalance the part '1 on the shaft 3. The part -lcZ, F ig.5, and can be fastened when adjusted by a set screw 16 or other suitable means.

The part2 ofthe cylinder is similar to but the reverse of part 1, and has abody portion 2a, and extension 2?), is cored out as at 20 and splined upon the shaft 3 as at 2d, and can be secured thereon by ascrew2e (see Figs. 2 and 5). g

The parts 16, 2b are complemental' and are arranged at diametrically opposite sides of the shaft'3', and substantially counterbalance one another, and they can be adjusted longitudinally of the shaft relative to each other. Each half of the cylinder is adapted to carry a blanket B of the usual type, one end of which may be fastened to one edge of the the partlbor 2b as indicated in 3.

In Figs. 1, 2'and3 the-partsl and 2 are 'shown as adjusted close together and form a short one-pageslong tWo-page-around 1m. pression cylinder. When thus adjusted the parts 1a, 2a will alternately coact with the plate or fudge cylinder t'to print successive sheets. 'vy

The fudge cylinder may comprise one or more fudge boxes 4, 4 of usual construction by any suitable means. As shown a form roller receives ink from a drum 5a to which ink issupplied by a ductor 56 from a fountain roll in a fountain 5d. The inking mechanism is not specificallyclaimed herein, and needs no further description.

When-sheets arerun to the folder to be folded without collectingi, it is desirable to print the fudge matter on every sheet; and in such case the cylinder halves 1 and 2 are adjusted as in Figs. .1, 2an-d 3 so that every successive sheet that passes between the fudge cylinder and the impression cylinder (1 and.

2) will be printed; the impression surfaces 16 and 2b alternately coacting with the fudge cylinder to print every passing sheet.

If thersheets are being collected at the folder, then only every alternate sheet should be printed by the fudge cylinder. At such time onlyone of the parts 1 or 2 of the impression cylinder shouldbe used; and, for example, as indicated in Figs. 1 and 5, the

part 2 of the cylinder is shifted on shaft 3 to a point where it will not contact with the fudge cylinder, but the part 1 of the impression cylinder is left in position to cooperate therewith. Therefore with parts adjusted as in 4 and 5 ateach revolution of the shaft 3 only every other passing sheet willbe printed by the coacti'on of the fudge cylinder andthe part 1 of the impression cylinder; and every alternate sheet will be skipped and not printed as the part 2 of the .impression cylinder is not in position to print, although it rotates with shaft 3.

This hit and skip method of printing only alternate sheets will be clear from Fig. 5,

in which it will be seen that at one time the web W is printed between the fudge cylinder 4 and the part 16 of the cylinder during one half revolution of shaft 3, but during the remaining half revolution of shaft 3 the web will not be printed as there is nothing to' impresszit againstthe fudge cylinder 4. But if both parts 1 and 2 are adjusted as shown in Figs. '1, 2 and *3, then every sheet of web WV passing the fudge cylinder will be printed by the alternate coaction of the parts 1 and 2 with the fudge cylinder 4., i

The utility and. advantages and adaptability of my novel cylinder will be obvious to those skilled in the art; and although I have illustrated my novel divided impression cylinder as used in connection with a fudge cylinder, obviously such divided cylinder might be used in connection with other plate cylinders or for other purposes in the art where it is desirable at. times to utilize the full diameter of a cylinder, and at other times to utilize only half of its diameter.

Also v while I' have described the two part cylinder as an impression cylinder, such cylinder could obviously be usedas a plate or printing cylinder if printing surfaces where substituted for the blanket B.
