SINGLE-PLATE ROTARY PRINTING-PRESS.

Specification of Letters Patent.

Patented Dec. 27, 1910.

Application filed March 15, 1909. Serial No. 483,600.

To all whom. it may concern:

Be it known that I, Hssnr F. BECIIMAX, of Battle Creek, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvements in Single-Plate Rotary PrintingIresses; and I hereby declare thatthe following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, which form part of this specifi' cation.

This invention relates to rotary-cylinder web-printing presses especially adapted for pr1ntin newspapers, and wherein the printfaccs are formed on stereotype plates fastened upon the peripheries of the plate cylinders and co-acting with adjacent impression cylindersto print a web.

The primary object of the presentinvention is to provide means for quickly and easily placing on the cylinders and fastening 1n position the tubular plates used on the single-plate press described in my Patent Number 867,230 dated October l, 1907, and the chief advantage of the present invention is that it permits the slipping of such plates onto such cylinders without in any way (listurhing the adjustments of said cylinders.

The present invention in particular is an improvement upon the press shown in my Patent No. 867,230 dated Oct ber 1st, 1907.

A particularly noticeable feature of my press is that the plate and impression cylinders are of very small diameter, so that an ordinary newspaper-page plate will ractically surround the circumference o the cylinder, and the press is designed for use with tubular stereotype plates, each plate containing but. one newspaper page of mat ter; and the press is so constructed that such small tubular plates may he slipped endwise on and oil the plate cylinders without removin the cylinders from their bearings, and witiout disturbing the cylinder bearings or their adjustment in any way. This is one very important practical feature of the invention, and greatly facilitates making ready the press.

- Another novel feature of the press is the means for fastening the tubular plates on the cylinders.

In the accom nmyin; drawings I have shown the invention as embodied in a press having four rotary perfecting mechanisms; in which each plate cylinder is adapted to ductions in the machine.

carry two tubular single page plates arranged end to end thereon, so that each perfecting mechanism will print four newspaper pages, the total capacity of such press being therefore sixteen pages. The total capacity of such a press can however be easily lncreased by lengthening the cylinders so that they can carry three or more tubular page-plates; or by adding additional perfecting mechanisms; or diminished by corresponding re- The several per footing mechanisms are all constructed alike so that the description of one will explain all.

I will now describe thefinventionmore in detail, as embodied in the press shown in the accompanying drawings, and will refer to the claims following such description for summaries of the parts and combinations of parts for which protection is desired.

The press as shown in Fig. 1 has four perfecting mechanisms A, B, C, D, which are arranged in two decks or planes, with two perfecting mechanisms in each deck. Each perfecting mechanism comprises two plate 100 and two impre sion cylinders, which in this instance are shown as extendin transversely of the press and arranged in t e same horizontal plane, the plate cylinders 1, 1, being outermost and the impression cylinders 2, 2 105 lying intermediate the plate cylinders. A strikingfeature of the press is the diminutive size of. these cylinders; in practice they are only half the diameter or less of the plate and expression cylinders employed 1 10 i l t -1 ho ordinary rotary web presses; ihe circu ierencc of each plate cylinder when the pl: is on in my press being merely equal lo the lengih of one newspaper pageplus i 5 the 'zwd margins between successive imsiuiiss'hereas in ordinary nresses he a. plates (see- Fig. are practically- "'XJJ. tubes, but nave a narrow slot g; the margin spaces of hepage,

I will now describe these devices.

In the press shown the plate cylinders are but two pages wide and both plates can he conveniently slipped on or oli the same. end

"sis cf die cylincler so that when the clamp is moved outwardly in the slot the clamp 1 moves inward and disappears below the surface of the cy inder see Fig. 7} but when the moved toward the other end of the y ruler is will rise in the slot, and appear properly shove the surfaces thereof (see Fig. 6). To the clamp block I is attached a red 1" :hich extends in a narrow elongafion of the slot toward the end of cylinder and is provided with a linger l on its exlrcmity which projects sufiiciently above the surface of the cylinder to engage the edge of a plate being slid on the cylinder. Belore the first plate is placed on the cylinder the clamp 1" is drawn back into the lower ortion of the slot and disappears as dcscri ed (see Fi T) then a plate P is slipped on the cylinder and as it is slid inwardly thereon its forward edge engages the finger 1 and forces rod 1'' tail or lateral hinges as nsu hack. causing clamp l to rise beside and 6Q a folding mechanism F at the opposite end against the inner edge of the plate see Fig. Tleu when the second platefi is slid on the cylinder it catches the clamp 1 and causes i': to move the first plate on until it abuts againsta stop 1 on the cylinder by which it is arrested in printing position. The smoud plate P is then clamped against lineal novement on the plate cylinder bv means of a slide block or clamp 1 (Figs.

After both plates have been slid on the cylinder as described, the bolt 1 is turned so as to first bring the clamp l into position to enter the grooved portion of the slot Fund as that it projects above the surface of the cylinder, and then the bolt moves the block inward against the edge of the second plate P and forces the latter to cause cle'np 1 to force and hold the first plate in position. Thus it is practically only necessary in securing the lates on the cylinder to operate bolts} as t e intermediate clamps 1* will be automatically positioned by the actof slip ping the first plate on or 011 the cylinder. Each plate cylinder is provided with a rotsry inking mechanism which may be of any suitable kind and which are sunply indicated at I in the drawings, as they form no part of the present invention, and it 1s unnecessary to describe same in full herein,

'as various kinds of well-known inking apparatus could be employed with the plate cylinders.

In the press shown four webs are employed each of which is or may be two-pages wide corresponding in width to the length of the page forms on the plate cylinders In the present instance each plate cylinder is supposed to carry two tubular page plates. If all four perfecting mechani ms are used the total maximum product or such press at each operation would be sixteen pages. The web a may be led from a roll at one end of the ess (3V9? suitable guides a, a", (1 to and etween the plate and impression cylinders in mechanism A; and then over suitable guides a, a", a, to aroller f at the top of of the press. In a like manner web Z may be led from a roll at one end of the rcss' over suitable guides b, 6 b, to an be tween the plate and impresion; cylinders in mechanism B and then over suitable guides 31, Z5 Z Z), to the roller f at the head of the folder I at the opposite end of the. machine. The web a may be similarly led from a roll at one end of the machine over suitable guides c, 0 through the perfecting mechanism C and then over suitable guides c c 0, c to the roller f above the folder. Similarly a web d may be led from a roll at one end of the press over suitable guides cl, d (1", to the perfecting mechanisnrI) and thence over suitable guides d, (i d, to the roller f at thctop of the folder. It will be observed that each web passes Without any lateral or edgewise deflection from the roll to the folder.

The cylinders in each perfecting mechanism are intergeared as usual to rotate at the same peripheral speed, and they are also adapted to be driven by suitable gearing, not shown, from a common drive shaft; it is unnecessary to illustrate this gearing as it can be varied according to the speed desired, and it will be readily understood and applied by any press builder. It will be understood that any one or more of the perfecting mechanisms can be put out of operamore of the perfecting mechanisms, for in- V stance web a after being perfected in one color in mechanism A could be directed over guide 0 to mechanism C and printed in multicolor and then can be led if desired direct to the folder like web 0, or it may be directed to and through another perfecting mechamsm.

It will be obvious that with such a press is possible to produce various sizes of papers in color, or multicolor, or in combinations thereof, as desired. By using a half width u 12b. and only one single page plate on each cylinder in any perfecting mechanism, two pages can be printed, and such single page web can be assembled with other webs at the folder. In this way six, ten. and fourteen page papers can be easily produced on this machine.

If the cylinders should be made three-page plates long the press described would be press can also be increased by adding addi- 2 E E t creased to eight pages.

itwill be obvious thatwith this press no :Jllecting is necessar and that only one set of stereotype plates is required, the printing being done on the straight run without collecting; whereas with the ordinary perfecting rotary cylinder web press it is nee-- essary to use a double set of plates when ing on the straightrun. With my press 1 can print as rapidly with one set of plates as can be done on the ordinary rotari s with two setsot" stereotype plates, thus effecting a'great saving in material, and in labor and time in ma dug ready the press.
