BATTLE CREEK, MICHIGAN, AssIGNoE To DUPLEX PRINTING rEEss COMPANY, OF BATTLE CREEK, MICHIGAN.

ROTARY PRESS, (DOUBLE LINE.)

To all whom rit 'may concern:

Be it known that I, HENRY F. BECEMAN, of Battle Creek, in -the'countyof Calhoun and State of Michigan, have invented certainy new and useful Improvements in Rotary Presses, (Double Line;) and I hereby declare that the follqwing is a full, clean-and exact description thereof, reference being had to the accompanying. drawings, which formpart of this specification.

This invention is an improvement in rotary cylinder web printing presses, particularly designed for high speed presses of large capacity;v and its objects are to provide a press in which newspapers of anynumber of pages, up' to the limit of the press, canbe printed in s multiples of twos, without any reduction of speed; to

do away with the collecting of papers; to lessen the number .of plates required in such press; and to usewhat' I term single-plate cylinders, -of half the diameter of the plate cylinders ordinarily employed,-V

and tubular stereotype plates that fit these small cylinders, insteadof the semi-circular plates ordinarily employed` l Infordina'ry rotary presses heretofore used the plate cylinders are of such ldiameter as to accommodate two stereotype plates around the circumference thereof, said plates beingordinarily` applied at diametricallyopposite sides of the 'cylinden-thatis, the circumference of the cylinder must be more than twice the length of one page of paper, and it is necessary in printing with such cylinders to make duplicate stereotype plates, unless the pages are to be collected; and when duplicate plates are not used the pages must be col-N lected, and ,therefore while the sizeof the papers may bethus increased, the speed of their production Y'is re'-V i duced one-half. I avoid the use of duplicate plates as required in straight run old style machines, and I also avoid the necessity of collecting the pages;l and prol duce the papers as rapidly asgthey could heretofore' be produced with duplicate setsVY of plates, and run the small plate cylinders .at the same peripheral speed as the old style duplicate plate cylinder presses could be run,-butvrequire onlyr half the number of plates toproduce the papers as are required inthe old styleV press, while obtaining the samespeed and product.

Preferably I construct the press with the single-plate cylinders only two pages long, that is-they will accommodate but two tubular plates arranged endto l end on each cylinden-and each perfecting mechanismv will therefore produce four pages, and the press illustrated in the drawings having four sets of such perfecting mechanisms, I can produce as muchas sixvteen newspaper pages at each operation of the machine.

Byemploying longer plate cylinders to carry thee or more tubular plates each, the capacity of the press can Specification of Letters Patent.

be correspondingly increased. The press moreover is complete press. Fig. 2 is a top -plan view thereof. Fig. 3 is a longitudinal sectional elevation of the press showing one mode of threading it for single color work. Fig. 4 is a similar View showing one mode of threading the press for multicolor work. Fig. 5 is a detail sectional view showing one of the tubular plates (stereotyped) applied to a cylinder.

A, B, C and D, designate four perfecting printing mechanismaall of which are constructed substantially alike, and eachcomprises two plate cylinders 1, 1 and two intermediate co-acting impressioncylinders 2, 2*. Preferably these cylinders are all disposed transversely of thepress, and the plate cylinders l, lafare of but half the diameter of the lordinary plate cylinders, and of the impression cylinders 2, 2, which impression cylinders are of the usual diameter empldyed with the ordinary large sized or double plate? cylinders. The plate cylinders l, 1a are but slightly greater in circumferential extent than the length of fone .page of Itype and therefore are adapted to carry one page plates P of tubularl form which plates substantially surround the circumference of the plate cylon or off the cylinder. At each rotation of the'im- `pression cylinder the entire tubular plate surface is Tpresented to the paper. Only one tubular plate has anism'will'prin't four pages, and the product of all 'four sets of perfecting mechanisms will be sixteen pages. As shown in Fig. 3, a separate web is led through beprinted in one color and assembled at the folder former Fr In this figuretheweb 'w is ledjin over guides a a2 down toiand between cylinders 1 and 2, in section A, then between-cylinders 2 and 2, then bev tween 2 andl, by which it is perfected, then down and under guides a3, a4, and. up and'over guide a5 to b, b2 and between the plate'and impression cylinders in section B, by which it `is perfected, and thence down under guide b3, around guide b4, and up and in over guides c, c2 to the perfecting mechanism C, whereby it is perfected and then passed down'under adapted toproduce a less number of pages in multiinder as indicated in Fig. 5 and can be slipped endwisek to be providedfoi each page. As each plate cylinder carries'two such plates obviously each perfecting mecheach printing mechanism sorthat the sixteen pages can In the drawngs-Figure 1 is a side elevation of the the'former F.l A web 'W may be' led in over guides .i

over guide b5 to the former F. A web w?, be ledv guide c3, around guide c4 and up and over guide c5 to cach page plate extending around the circumference of the former F. And the fourth web -w4 may be led in over guides ,l, (F to the perfecting mechanism D, and led thence down and under guide d, over' and around guide d4, and up and over guide d5 to the former F. 'Ihe webs being all assembled together at the former and thereafter folded in the usual manner. Each web goes directly through the press withvout being turned or deflected laterally at any time and thus the webs can be printed and traveled with great rapidity.

The same mechanism may be used to print one or more webs in multi-colors if desired. Thus, as illustrated in Fig. 4, the web w after passing through perfecting mechanism A, is led direct from cylinder 2*1 to and between the cylinders l and 2, of perfecting' mechanism G, and after passing through said perfecting mechanism itis led down and under guide c, over and around guide c", and up and over guide c5 to the former F. While web 1,02, after passing through perfecting mechanism B, is led direct to and through the perfecting mechanism D, and thence passes down and under guide d, over and around guide d4, and up and over guide b5, to the former F. The web w may receive impressions in one color in A, and another color in C; and similarly the web w2 may receive impressions in one color in B and another color in D. Other modes of threading the webs through the press may be employed. Y

Suitable inking mechanisms are provided for each plate cylinder as indicated at 3 in the drawings, but

Aneed no detailed description herein.

As shown, the press has two tiers of perfecting mechanisms, each tier comprising two perfecting mechan isms arranged in substantially the same plane, with the cylinders in the same plane and lying transversely of the press. Obviously the capacity of the press can be increased to any desired extent by`increasing the length of the printing cylinders in each perfecting mechanism; or by adding additional tiers of perfecting mechanisms; or by increasing the number of perfecting mechanisms in each tier. The press thus constructedowing to the small diameter of theplate cylinders-is more compact than presses employing the old double plate cylinders, and is less expensive to operate because of the greatly reduced number of plates required for a given speed and size of paper.
