7 Claims. (01. 101-180) This invention is a novel improvement in m impression cylinders 2, 2a and co-acting plate tary printing presses, and its primary object is cylinders 4, 4a. g v toprovide a novel perfectingand multi-color unit All the cylinders are mounted in framing F of for use in'the type of newspaperpresses in which any suitable construction,fand each plate cylin- I a number of similar interchangeable units and der is adaptedto carry singlepage tubular plates V one. or more folding units are arranged inline to P, which can be slipped endwise thereon and, produce a newspaper of anyf desired size up to a thereoff substantially as shown and described. in predetermined maximum, or to simultaneously Bechmans patent aforesaid. produce a plurality of newspapers of lesser size The plate cylinderst, 3a are supplied with ink 10; up to the total page capacity of the press.

In Figs. 1 and 2 each plate cylinder is arranged below and to one side of the axis of the cooperating impression cylinder. In Fig. 3 the lower plate cylinders are arranged exterior toand in the horizontal plane of the axes of the impression cylinders, while the upper plate cylinders are All impression cylinders are readily accessible from the floor and so are the plate cylinders.
In Figs. 3 and 4 a guide is provided so that a web W3 may be led successively between the lower plate and impression cylinders to be perfected thereby, as indicated in dotted lines in said figures, and then led under guide 10o up to and over guide I 0 or Illa to and between the cylinders 2, 4 and 2a, 4a as indicated in dotted lines. Similarly the web W41 can be led through the unit shown in Fig. 4;
It should be understood that a number of the novel units are to be arranged in a horizontal line with one or more folders so that the webs can be led from any unit in a straight line direct to the folder, and a plurality of webs assembled at the folder. A press of any desired totalpage capacity can bereadily built by assembling a plurality of such units, together having total page capacity desired. Various leads of webs have been indicated for producing papers in one color, or in multi-color; but the invention is not limited to anyparticular leads of the-webs. :The flexibility of production of such a press, and the commercial advantages of having it capable of producing multi-color work, will be readily understood and appreciated by those familiar wit the art.
The essential differences between my improved press and other tubular plate presses are (1) having the press cylinders below the impression cylinders so that the unit is very'much narrowed;
and (2) having the inking mechanism below the plate cylinders so that there is no material widening of the press by reason of the inclusion of the inking mechanism, and having the plate cylinders easily accessible from the side of thepress.

5. A double perfecting press unit for-amultium't press; comprising a unit frame, upper and lower sets of printing mechanism mounted in said frame, each set including two impression cylinders and two plate cylinders,the plate cylinders being arranged below their related impression cylinders and accessible from the adjacent outer side of the frame, inking devices for each plate cylinder mounted in the frame below such cylinder, and means for directing a web or webs through the unit.
6. A double perfecting printing-press unit for a multi-unit press; comprising a unit frame, upper and lower sets of printing mechanism mounted in the frame, each set including two impression cylinders and two plate cylinders, the plate cylinders being arranged below the related impression cylinders and accessible from the adjacent outer side of the frame, inking devices in'the frame for each plate cylinder arranged below such cylinder; and means on the frame for directing a web exterior to the inking devices of one set to theplate'and impression cylinders of such set, and then between the inking devices of the other set to the plate and impression cylinders of such set. a r
-7. A double perfecting and multi-color unit for a multi-unit press; comprising a unit frame, upper and lower perfecting mechanisms mounted 'in' said frame, each including two closely adjacent impression cylinders and two plate cylinders, each plate cylinder being arranged below the related impression cylinder, inking devices in the frame below each plate cylinder; means in the frame for directing a web between the plate and impression cylinders of one set of printing mechanism, and means for directing separate webs between plate and impression cylinders of the separate printing mechanisms. i
