Application tiled February 10, 1912. Serial No. 676,702.

To all fui/0m it m agi concern Be it known that I, Josemi J. WALsnn, a citizen ot' the United States, residing at Chicago, in the county of Cook and State ol? Illinois, have invented certain new and uset'ul Improvements in Printing-Presses, ol.

which the following is a specification, reifer ence being' had to the accompanying draw-- ings.

My invention relates to printing presses,

and its object is to provide a new and improved printing press n'iechanisin, one of the principal objects of which is to rovide a printing press Whose printing cylinders are of a length adapted to print a web of paper, of .a width of one page length, and whose form cylinders contain one stereotype plate on each semi-circnrnference With the column rules running parallel with the axis of the cylinder and in which a fourteen-page paper ma51 be printed from a machine adapted to carry sixteen plates, a ten-page paper from a machine adapted to carry twelve plates, and a six-page paper from a machine adapted to carry eight plates, and so on. Another object of my invention is to provide a new and improved arrangement of the several sets of printing mechanism and printing couples in which the rolls of papel' are easily accessible, and the printing mechanisms so arranged that additional sets ot' printing cou-ples may t be readily added thereto.

In the drawingsi,-Fignre 1 is a diagrammatic side elevation of a press containing my invention; Fig. 2 is a side elevation showing the driving gearing which l prefer to use; and Fig. 3 is a section on line 3`3 of Fig. l.

Referring to the drawings,-in the forni in which l have illustrated my invention,-- the press is provided with tour sets of printing couples adapted to print lrorn four rolls.

fl: indicates the press .trames and 5 the folding `frame, which are preferably mounted npon a single base, as (l.

As shown in the drawings, the press ernbodies four of printing mechanisms, A, ll, C, and l), altliongh the number, ol' course` may be more or less. .Each of these presses is composed of a set of printing couples comprising two form and two impression cylin ders and correspoinling inling mechanism. The four presses are arranged one behind the other in the same vertical plane, and the two 'sion-cylinder, and Q=l the inling mcelian printing couples oi each press are arranged above each other in the saine 'vertical plane. .Referring to press il, indicates the lirst 'l'orincvliinler and tl a. ferrosiendingimpression-cylimler. t) indicates an inkii'ig mechanism 'For 'torin-cjflincler i' o'l' an)1 wellln'iown torni and deseriiition.

Press D, which is like the other presses above described, is adapted to print from a web of paper 1.). 41 indicates the first formcylinder, it2 the first impression-cylinder, 4;?) inking mechanism for form-cylinder 11, 4i the second form-cylinder, 45 the second impression-cylinder, 4G in king mechanism for the second form-cylinder 44. rl`he web D passes around a suitable guide-roller, as. L17, between form and impression cylinders 41-42, thence over suitable guide-rollers, as 45t-4:9, between form and impression cy inders 44Jl5,thene around suitable guiderollers, 50--51, to the gathering rollers 17-18, where it is associated with the other webs. As thus used, the press, it will be seen, contains sixteen plates and is adapted to print a sixteen-page paper, 'the' four webs gathered by the gathering` rollers 17- 18 and superposed in register with each other, are led between cylinders l'52#53. 'lhe cylinder 52 is of a circumference equal to two page widths plus margins and is provided with a suitable' cutting-blade 52"L which, coacting with corresponding cutting blocks 54-55 on cylinder 53, operatesk to sever the superposed webs upon every second transverse margin. The cylinder 53, which is of a circumference equal to four page widths, is provided with the usual 'folding` blades 56 which, operated in any well-known and approved manner, are adapted to engage the central margins of the sheets and the usual folding rollers 57, which operate in the well-known way to fold the sheets transversely of theii` central margins, from which they may be delivered to any suitable folding and delivery mechanism, as 58, which is only conventionally no part of.m pre`sent invention. As thus run, the press will produce a sixteerrpage' paper consisting of four sheets, each containing four pages feldedcentrally on their central transverse margins.

59 indicates an impressiori-cylinder, G0 a enacting form-cyliinler, and G1 suitable inking mechanism for forin-cylinderjo() which is used in ease it is desired to pri'nt one of the webs in a plurality of colors. In such case the web A may not be used and the web B is used; In this case the web l5', after being lcd between form-cylinder 1E) and impression-cylindcr 20, is led, as indicated iu dotted lines, around guide-roller 25a and thence across around roller 13 be'- tween form cylinders 7 and 8, as indicated in dotted lines therein, thence betweenilnpression-cylinders 59 and GO, thence down vover roller 123, between form-cylinder 10 and impression-cylinder 11, thence upward, as

indicated in dotted lines, over a suitable roller G2 and over roller 25,as indicated by dotted lines and arrows, down between formeylinder 22 and impression-cylinder 23, and thence over rollers 2G, 27 and 28, to the gathering rollers 17-1 8. In this case, of course, the form and impression cylinders 78 will have the direction of their rotation reversed, and this is done by any suitable and well-known mechanism.

In Fig. 2 I have shown the gearingfor the press, which it is unnecessary to describe in full further than to say that (35#(36 ind' :ate the main driving pinions, which, by a suitable gearing (not shown), are connected up with the various moving parts of the press. F or the purpose of reversing, a gear ('37, which is a double-faced gear, is provided, and a gear 68, which is adapted to slide longitudinally upon its shaft so that by such sliding it may be brought into mesh with gear 67 for the purpose of reversing the same. This, however, I have Shown only for purposes of illustration, as it is one weilknown vmethod of reversing the rotation of printing cylinders and of itself forms no portion of my present invention. By this means web B may be printed on both sides only in black and upon one side with a plurality of colors, and this side, as is the obvious arrangement, will be the outside of the paper when it is folded. For the purpose of producing a paper which may consist of six, ten, or fourteen pages, press C is provided with gearing by which it may be slowed down and driven at one-half the speed of the other presses.

This may be done in any well-known and approved manner, as by gears (S9-.#70 which are adapted to mesh, respectively, with gears 71-72, as is shown in Fig. 2. When the press is to be driven at full speed, the gear G9 is in mesh with gear 71. lVhen slowed down to half speed, the gear is brought into mesh with gear 72, which, in this case, does the driving of press C. As this slowdown mechanism may be of any well-known and approved form and construction, l have illustrated it only diagrammatically and only brieliy referred to it in my description, as of itself it forms no part of my present invention. 1in this ease, web C', being led through pressI C, which is driven at one-half speed, is printed upon both sides, and the forms upon each half of each form-cylinder will be duplicates of each other so that a series of two-page duplicate prints are'produced by press C. '.lhe web thus printed, after being lcd around rollers {5S-39, instead of'being led over roller llOto the gathering cylinders 17 and 1S, is led between two cutting cylinders T3- 74, .which are of the well-known form and description, and are of one-half the diameter of the cutting cylinder 52 and are, therefore, adapted to sever ucts are folded out together between fo dingy rollers 57H58; By thus using webs A, B', C',

and D with the press C slowed down to onehaltI of the speed, it is obvious that with a,

sixteenplate machine a fourteen-page paperr can be produced. By silencing oneY or more of the printing presses, it will also be obvious that a ten-page paper will be produced on a twelve-plate machine,` or a six-page paper upon an eiglitplate machine, and so on.' 'By adding to the number of presses, corresponding changes, of course, may be niade.

It will be understood that I do not re# strict my invention to use in the precise method of operation Set forth above, except specifically claimed, but that my devices may be operated in any appropriate manner without departing from my invention and the claims are to be construed accordingly.

What I claim asm invention, and desire to secure by Letters atent, is-- l. A printing press having, in combination, a plurality of printing mechanisms arranged one behind the other, each printing mechanism being composed of two pairs of printing couples arranged one pair above the other and adapted t-o print upon a web one page length in width, the form-cylinders being adapted to contain upon each semi-circumference a page form with the eolum'n rules running parallel with the axis oi the cylinder, means for assembling the printen webs in registry, means :for cutting said webs upon every other transverse Inargin, means for folding the severed sheets transversely along their central margins, means for slowing down one of said presses to run at onehalf speed, cutting mechanism adapted to sever said slowed-down web upon every transverse margin, means for leading the slowed-down web to said cutting mechanism, means for associating said severed sheets in registry with the other webs, and an auxiliary printing couple between which one web may be led for rintin in color in addition to the printing in blac 2.
