' This invention relates to new and useful improvements in printing and more particularly to a process and mechanism for producing a newspaper having certain of the pages distinctively tinted or colored, as well as to the novel product of the process. Objects and advantages of the invention will be set forth in parthereinafter andinp-art will be obvious herefrom, or maybe learned 1o by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, construction, arrangements, combinations and improvements herein shown and described.

The accompanying drawing, referred to herein and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

Of the drawing Fig. 1 is a diagrammatic view showing the arrangement and combination of the various elements constituting the present preferred embodiment of the invention; Fig. 2 is a detailed diagrammatic view, broken away in parts, showing a portion of tghe printing press and particularly the turner Fig. 3 is a detailed diagrammatic view of the tinting or coloring attachment forming a portion of my invention;

Fig. 4 is a detailed sectional view of the tinting cylinder shown in Figs. land 3; and

Fig. 5 is a plan of the novel product produced by the process and mechanism referred to.

In the production of certain "editions of newspapers it has been customary, with many of the metropolitan dailies, toemploy one web of paper dyed a color different from that of the remaining webs thereby produc- 5 ing a'product in which certain of the sheets are distinctively colored, for the purpose of identifying the particular edition. This practice necessitates carrying on hand a plu-' rality of diiferent kinds of paper-and, as gen- 1929. Serial in. 354,909.

which four of the pages are colored dilferently from the rest. The present invention .is directed to the provislon of a printing press for producing colored or tinted a distinctive color.

The general arrangement of the printing and folding units in the present preferred embodiment of the invention, exemplarily illustrated herewith as applied to a straight line rotary printing press, comprises, broadly considered, a plurality of rotary printing couples for perfecting one or more webs of paper, suitable associating, folding and cutting mechanism, and means for tinting or coloring a portion of one of the webs prior or subsequent to the printin of the web.

According to the pre erred embodiment, means are also provided associating a plurality of untinted webs with the tinted web I and for associating and folding the printed and tinted web so as to place the tinted sheet outermost of the printed product. Means arealso provided for variably positioning the tinting orcoloring means forcoloring other pages than page one of the printed product. Means are also provided for silencing the tinted means when it is not desired to produce a newspaper having a tinted page, and other means are provided for registering the tinted web with the impressions of the printing couples and for registeringthe tinted and printed web with respect'to the folding and cuttin provi ed a drying means for dryln the web, as it passes through the press an .prior to the time it is printed. 'Means are also provided, for use when running collect runs, whereby only one page of the collected product is tinted.

mechanism. Optionall. there is erally practiced, produces a newspaper in I The present invention also providesanovel mo ing couples.

It will be understood that the foregoing 'general description and the following detailed description as well are exemplary and explanatory of the invention but are not restrictive thereof.

In the accompanying drawing illustrating the present preferred embodiment of the invention, the invention'is shown as applied toa conventional straight-line rotary printing press, although it can equally well be applied to other forms of press construction.

As shown, there are provided means for perfecting a plurality of. webs of paper, and for folding, associating and cutting these webs to form newspapers of varying size. As embodied, these means comprise a plurality of superposed rotary printing couples, each including a pair of cooperating printing and impression cylinders, 10 and 11, re-' spectively, for printing webs of paper 12, preferably four pages wide, which are fed from web rolls 13 and supplied to the print- Suitable inkin mechanism 14 is provided for each of the printing cylinders. After the webs of paper are printed they are led under guide rollers 16, associated and fed to the folding mechanism, which in the present instance comprises a pair of formers 17, side by side, provided with folding andcollecting cylinders 18, and cutting cylinders, in the usual manner. When using a web four pages wide, slitters 20' may be employed to slit the web ust prior to its being fed over the formers 17, thus producing two separate sections of the newspaper. d

When desired, all the webs can be passed over a single one'of the formers 17 and for this purpose, there are provided slitters 21 and turner bars 22, for each of the webs.

The printing cylinders 10 and impression cylinders 11 are preferably made two pages in circumference .and, as is usual, the cut, associated and folded sheets may be collected on the folding cylinder 18, if desired.

-' According to the present invention, there are provided cooperating tinting or coloring meansfor coloring one or more, and preferably the first, pages of the products of the press, and as embodied, there is provided a tinting mechanism for applying a tinting or coloring medium, suchas; ink, to a portion of the web of paper. In the present embodiment, these tinting or coloring means com-- prise a cylinder 24 having a substantially smooth surface, cooperating with a rotatable impression cylinder 25 having a -resilient covering-.and mounted in the press frame, so that one of the webs can. be passed' between the tinting and impression cylinders. Suitable inking means are provided, and comprise an ink drum 26, fountain 27, distributing rolls color only the first page of the first section.

For accomplishing this purpose and for tinting alternate successive pages along one of" the webs, the tinting cylinder 24 is provided with removable-semicylindrical shells 31 each having a smooth metal surface, so that alternate pages of the 'web roll will be left untinted.

The constructionof this cylinder is shown more in detail in Fig. 4, where the semi-cylindrical shells 31 are secured to the cylinder 24 by keys'32 set in registering key-ways in the shells and cylinders. When only the alternate pages are to be tinted, one of the shells is removed. To insure coloring the whole of the proper page, the shells are made with abutting edges, and when both shells are in position on the cylinder, they substantially completely encircle the cylinder.

For moving the tinting mechanism from one side of the web to the other, in order to tint other pages than the first, the tinting cylinder 24 and and inking mechanism are, in the present embodiment-mounted as a unit in a supplemental frame variably positionable transversely of the web. -This supplemental frame may comprise side members 33 and 34, slidable along supporting and guide rods 35 mounted in the press frame 36. A shaft 37,

provided with a key way 38 is provided for driving the tinting cylinder. Any suitable means can be provided for holding the supplemental frame in any one of its several positions. g

For registermg the impression of the several couples with each other, with the folding for correcting minute variations in register suitable compensators 39can beprovided between the tinting and printing units and between the printing couples and folding units. If desired,'means may be provided for at least partially drying the tinting ink after it is applied to the web and before the web is printed, and as here embodied, these means comprise adrier 40 capable of bloiving' a strong blast of heated air onto the web "as it passes over roller 41.

For silencing the tinting-mechanism, when the edition does not require the use of the distinctively colored page, means are provided for withdrawing the web from contact with the tinting cylinder 24. As embodied, pressure roller 25 deflects the Web 12 out of its normal path between rolls 41, 42, when the tinting mechanism is in use, and the supporting shaft for pressure roller 25-is mounted in eccentric bushings 43 which can be turned to space roller 25 away from .cylinder 24.

While shown as applied to a straightline press in which page 1 is printed on the upper deck, it is, of course, obvious that the invention can be used with other types of printing presses such as those employing inverted folders, and unit-type presses. In the case of a unit-type press, the tinting mechanism would be formed as a unit and would be movable from one unit to another dependent on which unit is employed for printing page one of the newspaper.

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advantages.
