Application filed. February 26, 1910.

Specification of Letters Patent.

Patented Get. 4, 1910.

Serial No. 546,232.

To all whom it may concern:

Be it known that I, JOSEPH L. FIRM, a citizen of the United States, residing at Berwyn, in the county of Cook and State of Illinois, have invented certain newand useful Improvements in Printing-Wachines, of which the following is a specification.

This invention relates to web perfecting rotary presses which will produce magazines or pamphlets, printed, cut, folded and stapled, at one operation.

In my application for a patent Ser. No. M2343, filed Feb. 5, 1910, I disclose a printing machine with a series of decks, arranged in two opposite parts and delivering toward the middle for folding and stapling the product, each deck consisting of one form and one impression cylinder.

The present invention is an improvement on or addition to the machine disclosed in said application, and includes a color deck for printing one of the webs in colors, and as a modification, the color deck may be provided with an additional roll or web which can be printed in colors, 011 one or both sides, or in one color, and associated with the other webs. The color deck includes three form cylinders, one for printing blue, one yellow and another red, these being primary colors from which various secondary colors may be produced. The key block will be printed in black, thus covering up any deficiency in the register of the color blocks, the black color being printed on the second or middle deck, the top or third deck being the color deck, and the web being then associated with other webs from the first deck, and from other decks at the opposite end of the machine, to form a cover for the book or pamphlet, or additional leaves for the same in colors it required.

In the accompanying drawings Figure 1 is a diagrammatic side elevation of part of the machine, showing the color deck. Fig. 2 is an end elevation, the paper rolls and inkers being removed. Fig. 3 is a diagrammatic side elevation of a modification. Fig. .4 is a side elevation of another modification.

As disclosed in my said pending application, I make use of a perfecting couple consisting of a form and an impression cylinder between which a web is twice passed, once at each end, with turning bars and rollers to turn the web and pass it from one end to the other of the cylinders, in a manner illusof my Patent inder E thence it passes to form cylinder F where it receives its second color, thence to form cylinder G for its third color, thence back again to impression cylinder B, and is printed in black by the other half or end of the form cylinder C, finishing the web in black and in primary and secondary colors. Thence the web passes under the roller 7 where it is slit by the slitter 8, thence over the associating bars 9 and 10, and between the roller 11, 12, and 13 where it meets the web A and the associated webs passed to the rollers 14 and 15, and are slit again it re quired by the slitter 1G. Thence the webs pass to the stapling, transverse cutting and folding cylinders H and I, being finally delivered through the rollers 18 and 19, and by the rotary fly 17, to the apron 20.

The web A passes from its roll over the rollers 21 and 22 to impression cylinder K and is printed on its first side by one end of form cylinder L, thence it passes under the roller 23, over the turning bars 2 1, and under the roller 25 to the other end of impression cylinder K and is printed on its re verse side by the other end of form cylinder L after which it passes under the roller 26, where it is slitted by the slitter 29, thence to the associating bars 27 and 28, thence under the roller 30 and between the rollers 11 and 12 where it meets the web A passing therewith to the stapling mechanism as above described.

The two lower decks shown may be duplicated at the opposite end of the machine, to deliver the webs indicated at B and B for association with the webs A and A before being transversely cut and stapled.

The mechanism shown will complete a pamphlet or signature of thirty-lave pages in one color, and thirty-two pages in various colors, including a cover, or sixty-tour pages in all. The form cylinders have four pages abreast and four pages around the cylinder,

the plates being double pages, although they may be single if required, and the column rules may be either parallel to or at right angles to the axis.

In the modification shown in Fig. 3 the additional web A passes over rollers 100, 101 and 102, to impression cylinder 1), the form cylinders E and F having been backed oif or moved away from contact by screws 103 and 10st and shaft box 105, and screws 106, and 107 and shaft box 108 respectively. The web passes over the impression cylinder D, and is printed upon its first side by one end or half of form cylinder G, in any color, thence under the roller 109, over the turning bars 110, over the roller 6, to impression cyl inder D, is printed upon its reverse side by the other end or half of form cylinder Gr, thence under the roller 111, and between the rollers 112 and 113, where it meets the webs A and A, the web A, in this instance, being carried directly around the impression cylinder B from the roller 5, instead of being carried to the color deck as in Fig. 1. From the rollers 112 and 113 the three associated webs pass between the roller 111 and slitter 115 after which they are folded over the longitudinal folder S from which they pass to transverse cutting, folding, and stapling mechanisms which, however, will be arranged at a right angle to those shown in Fig. 1. The three webs as indicated will make pamphlets of ninety-six pages, printed in one color.

M, N, O, P, and Q are inking devices, old in the art.

In the modification shown in Fig. a the web A is passed through the color deck without disturbing the form cylinders E and F, the webs being printed in three colors on both sides, passing first under the roller 200, thence under the roller 6 and around the impression cylinder D where it is printed in colors on one side by one end of the form cylinders E, F and G, thence under the roller 109 and over the turning bars 110, and around the other end of roller 6 and thence around the impression cylinder D where it is printed by the other ends of color cylinders E, F, and G, finally passing out under the roller 111 for association with the other webs as above described. In this case I introduce an offset web in the manner shown in my U. S. Patent No. (586926, the web A being one, two, three or four page widths according to the number of pages required for the cover of the book or pamphlet, in colors.

What I claim as new is 1. In a multiple web printing machine, the combination of a plurality of decks, each deck including form and impression cylinders with their axes in substantially the same horizontal plane, whereby the decks are spaced one above the other, and one deck being provided with means for color printing, means to feed webs from rolls to the respective decks, the respective rolls being located in substantially the same horizontal plane as the corresponding decks and all at the same end of the machine, means to pass the webs twice through the couples, once at each end, means located in the spaces between the decks to pass one web from one deck to the color deck, and means to assemble and deliver all the webs at the opposite end of the machine.

2. In a web printing machine, the combination of a plurality of superposed spaced decks, one deck including a single color printing couple between which the web is twice passed, once at each end, and the other deck including multiple color couples, the couples in each of said decks including cylinders in substantially the same horizontal plane, means at one end of the machine to feed webs to all the decks, means in the spaces between the decks to turn the web after its first passage through the single color couple and pass the same from one end to the other thereof and to the color couples, means to then return the web to the single color couple for its second passage therethrough, and means at the other end of the machine to associate and deliver webs from all of the decks.

In a web printing machine, the combination of three sets of printing mechanisms located one above the other, the two lower sets each having a form and an impression cylinder in substantially the same horizontal plane, between which a web is passed, and the upper set being spaced from the lower sets and having an impression and a plurality of color form cylinders cooperating therewith, and between which a web may be twice passed, means in each mechanism located between the couples of the respective sets to turn a web passed between the cylinders at one end thereof and pass the same between said cylinders at the other end, means at one end of the machine to feed webs to the sets, and means to associate the webs from the respective sets and deliver the same at the opposite end of the machine.

In testimony whereof, I afiiX my signature in presence of two witnesses.

JOSEPH L. FIRM.
