Specification. of Letters Patent.

Patented Oct. 10, 1905.

Application filed February 2, 1905. Serial No. 243,862.

on the press patented to me, No. 677,818, dated June 18, 1901.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

With my present invention the same number of pages may be printed by the employment of just half the number of forms.

newspapers ordinarily require sixty four forms or plates they may on my present press be printed from thirty-two forms or plates. 1

In addition by the use of my present invention supplement pages may be printed and assembled as separate signatures.

In many of the large newspaper-oflices the time consumed in making the necessary matrices is considerable and is a constant expense.

In the accompanying drawings, Figure 1 is a diagrammatic side sectional elevation of the press. Fig. 2 is an end elevation. Fig. 3 is a plan. Figs. 1 and 5 are plans of form-cylinders, showing two ways of grouping the forms. Figs. 6 and 7 are details in plan showing the manner of combining the different Web-sections.

The construction and operation will be evident from the following description, showing the travel of the webs.

The web A passes over the rollers 1 2 to impression-cylinder Cand is printed upon by form-cylinder D. Thence it passes over the roller 3 to impression-cylinder E and is print ed upon the opposite side by form-cylinder F, thence over the roller 4 and over the bar 5 and is slit by the slitter 5, and thence over the bars 5 and 5, thence over the roller 30 and between 31 and 32, where it meets the web A. This web A has passed from its For instance, when four copies of sixteen-page roll over the rollers 6 and 7 to impressioncylinder (,ir and is printed upon by form-cylinder I-I. Thence it passes over the roller 8 to impression-cylinder I and is printed upon its opposite side by form-cylinder J, thence over the roller 9 and over the bar 10 and is slit by a slitter, and thence over turning bars and between the rollers 33 and 34c, thence over the roller 32, when it meets the web A and passes with it between the rollers 31 and 32 over the former 37, thence between the rollers 35 and 36 to the folding-cutter 39, thence to the roller 39, which delivers the papers folded in one product over an apron I L. The sets of printing mechanisms above described have an end feed of the web and side delivery. Ihey are associated with other sets having a side feed and end delivery, now to be described. The web B is placed at the side of the machine, and the web passes over a roller to a turning-bar 100, thence under a roller 11 to impression-cylinder K and is printed upon by form-cylinder D. Thence it passes over the roller 12 and under roller 13 to impression-cylinder L and is printed upon its opposite side by form-cylinder F. Thence it passes under the roller 14: and is slit by a slitter 15. Thence it passes over the bar 16 and between the rollers 17 and 18 and over 19 and under 20, where it meets the web B. This passes from its roll at the side of the machine adjacent the lower group over a roller to a bar 101, thence under a roller 22 to impression-cylinder BI and is printed upon by form-cylinder H. Thence it passes over the roller 23 and over .24: to impression-cylinder N and is printed upon by form-cylinder J on its opposite side. Thence it passes under the roller .25 and is slit by the slitter 26. Thence it passes over the bar 27 between the rollers 28 and 29, thence between the rollers 17 and 18, where it meets the web B and passes with it between the rollers 19 and 20 to the former 27, where it is folded longitudinally, thence between the rollers I0 and L1 to the folding-cuttereIQ, thence to the apron I5, which passes over a roller I3. These mechanisms make four copies of sixteen-page papers complete.

u.- b 0 (Z c f g [L are inking-cylinders of the ordinary construction; but to make the platecylinders more easy to get at the inking-cylinders a, d, c, and la may be removed in the manner shown in United States patent to me, dated May 8, 1900, No, 648,938.

By the United States patent granted to me and dated June 18, 1901, No. 676,816, Ishow two printing mechanisms side by side. In practice I find that space required is quite an object, where it is an easy matter to get headroom, but not so easy to get space, and to accomplish this object I place the different printing-couples over the other and gives me a more compact machine. Also in placing the folders one at the side and one at the end is quite an advantage. In printing ten-page papers two quarter width webs are used, one in each half of the press, and in making twelve-page papers two half-width webs are used, and no slitting or second turning of the webs is required. In making fourteen-page papers two three-quarter-width webs are used, which are slit and turned, as in making eightpage papers and as illustrated in Fig. 7, the

webs A and B making four copies of sixpage papers and being combined with the webs A and B, which are producing eightpage paper, in the same manner in which the webs are combined when producing sixteenpage papers. In all sizes of papers eight pages are printed on one half of the press and the remainder upon the other half, and if the remainder is less than eight pages a web of.

form-cylinder is shown such as would be used in printing ordinary newspapers. In Fig. 5 forms of -a smaller siZe are shown, such as would be used in printing a magazine supplement, which would be folded separately and inserted within the paper, but not pasted thereto, so that it may be removed for reading, if desired. The division of the plates on this cylinder is suchthat two or more of the plates occupy the same space as one of those such as shown in Fig. 4:.

IVith this machine it is possible to print eight-page papers with one section and to print four, six, or eight page papers with the other section, which shall be folded and inset with the first section and yet be independent thereof, so that it may be removed for read- I impression-cylinders, of means for conducting two webs through each pair, to print both sides thereof, and means for associating two webs, one from each pair, and delivering the same at one side of the machine, and for associating the other two webs and delivering the same from another side of the machine.

2. In aprinting-press, the combination with two superposed groups of printing mechanisms, of means for conducting two webs through each of said mechanisms and printing both their sides, and means for associating and delivering together one web from each group.

3. Inaprinting-press, the combination with two superposed pairs of printing-couples each couple having one form-cylinder and upper and lower impression-cylinders, of two webrolls at the end of the machine and two at the side, feeding respectively to the upper and lower impression-cylinders of each pair, to be printed on both sides by the form-cylinders, and means for delivering the end webs from the side of the machine and the side webs from the end thereof.

4. In a printing-press, the combination with two superposed groups of printing mechanisms, each group having upper and lower'sets of perfecting-couples, of end feeding-rolls supplying webs to one set of couples and side feeding-rolls supplying webs to the other set, and means to associate, cut and fold the webs from the respective upper sets, and from the respective lower sets, and to deliver the same separately.

5. In a printing-press, the combination with two superposed groups of printing mechanisms each comprising two perfecting formcylinders, and upper and lower impressioncylinders for each form-cylinder, of means to feed one pair of webs between the upper impression and the form cylinders of each group, and another pair between the lower impression and the form cylinders of each group, and means to separately associate and deliver the webs of the respective pairs.

6. In aprinting-press, the combination with two superposed groups of printing mechanisms, each group comprising a pair of couples, and each couple comprising a form-cylinder and upper and lower impression-cylinders, forming in all, two perfecting mechanisms, in each group, the respective couples of the upper group being geared to the respective couples of the lower group, of means to feed separate webs to each perfective mechanism, and means to deliver the same together.

7. In a printing-press, the combination with two superposed groups of printing mechanisms, each group comprising a pair of couples, and each couple comprising a form-cylinder and upper and lower impression-cylinders, forming in all, two perfecting mechanisms, in each group, the respective couples of the upper group being geared to the respective couples of the lower group, of means to feed separate webs to each perfecting mechanism,
