INTAGLIO AND RELIEF PRINTING DEVICE.

Speccation of Letters Patent.

Application filed February 14, 1967.

Patented Oct. 22,1912.

sei-iai no. 357,253.

To ali whom iz' may concern:

Be it known that l, HENRY A. lien `Woo1 a citizen of the United States, residing at New York, in the county of New York and State of New York, liave invented a new and useful Intaglio and Relief Printing Device, of which the following is a specification.

in my application for patent, Serial No. 347,028, filed December l0, 1906, I have set forth, among other things, a construction of combination printing member in which the intaglio printing surface is higher than the relief whereby the two printing surfaces can be inked by the same mechanism and the intaglio surface can be scraped or cleaned by a blade which may, if desired, be fixed in stationary position so as to clear the relief surface.

Photogravures, and the like are printed from etched intaglio plates, the title, frame, or other like device being printed in letter press. These two styles of printing are now run at separate operations, necessitating two handlings of the work.`

Now one object of the present invention is to provide for printing sheets of this and similar characters from intaglio and relief surfaces, on the same support, which is preferably a cylinder, with one handling only, so that either style of printing may be superimposed on the other or put in juxtaposition in a most simple and convenient manner.

Another object is to provi'de means whereby the inking of the two'kinds of plates may be provided for in such a manner that the inking devices will not interfere with each other and will not engage the wrong plates. This is accomplished by setting the one surface, preferably the relief, higher than the other; that is 1f upon a cylinder, farther from the axis and making the other inking device movable, or in another form of the invention, making both surfaces at the same height and providing inking devices for the relief and intaglio, both of which are movable.

In one form of the invention, also, the impression cylinder makes more revolutions than the printing cylinder as willappear hereinafter.

Reference is to be had to the accompanying drawings which illustrate this invention, and in which-- Figure l is a longitudinal sectional view of a portion of rotary sheet printing press in which the impression cylinder makes three revolutions to one of the printing cylinder and the relief surface is higher than the intaglio surface. Fig. 2 is a similar view in which both printing surfaces are in the same cylindrical plane; that is, at the same height, and Fig. 3 is a similar view of a device constructed in accordance with this invention for printing on a web in which the plates are substantially scmicircular and the impression and printing cylinders are of the same size.

ln Figs. 1 and 2, it will be seen that an, impression cylinder a is shown of smaller4 diameter than the printing cylinder Z2, the printing cylinder carrying two printing surfaces, shown in the present instance as in the form of a relief plate c and an intaglio plate CZ. These plates are similarly shown in both of these figures except that in Fig. l the relief plate is shown as in a higher' plane than the intaglio plate; that is the relief printing surfaces, when the device is constructed in the form of a cylinder, are at a greater distance from the axis thereof than the intaglio printing surfaces. The object of this construction is to provide for permitting the relief inking devices e to be fixed in stationary position so that they may engage the relief surfaces and clear the intaglio surfaces. With this construction, is shown a separate intaglio inking device f and cleaning blade g mounted in a frame 72., which frame is movable automatically to move the inking roll f and cleaning blade g toward and from the cylinder, whereby they may engage the intaglio surface as it passes the position in which the intaglio inking device is set and move back to clear the relief plate. Gn account of the relief plate being in a higher plane, no such construction is necessary for the relief inking device.

The movement of the frame L may be provided for in any desired way within the scope of this invention, as expressed in the claims. I have shown it as mounted to reciprocate in ways 7c, the shaft Z of the printing cylinder being provided with a cam m for operating the frame, This cam obviously automatically moves the inking device and cleaner toward the cylinder when the intaglio plate approaches the inking device, holds it in contact therewith until the plate passes beyond. it and then withdraws the inliing device and cleaning blade.

ln the form shown in Fig. 2, the two plates and (Z are shown as in the same plane. rihis construction is advisable in some instances as then the two surfaces register in the same way with the impression i'zylinder and contact with it under the same pri-essuie. ln this case, the parts f, f, g, it, Z', Z and m are the same as those described above. The relief inlring mechanism c is, however, mounted on a movable frame 0 which reciprocates in ways j), a cam Q being provided on the shaft for operating it in a manner similar to that above described. The cam Iin may be so designed as to perform both functions if desired. It is to be understood, however, that any other desired means for moving the inking meclianism can be adopted.

ln both of these forms, the impression cylinder maires three revolutions but does not rise and fall., being so geared with respect to the printing cylinder. lts first revolution prints from the relief plate, its second from the intaglio plate, while its third delivers the sheet. That portion of the plate cylinder which carries no plate has no contact with the impression cylinder during delivery, it being reduced in diameter so that it clears the impression cylinder.

ln the form shown in Fig. 3, this invention is illustrated as modilied in such a way that it is adapted to print upon a web. Here the impression cylinder A is of the same size as the printing cylinder B and makes the same number of revolutions. rihe relief and intaglio@plates C and l), respectively, are substantially semi-circular in form. rlhe inlting deviceA Pl and F move in substantially the same way as is illustrated in Fig. 2 and they may be provided with mechanism of a similar or any other kind for moving them, but this is not shown in this figure. lllhen the invention is applied to flat printing plates or impression members, similar '(nistrnctions are employed.

illhile l have illustrated and described certain forms in which the invention may conveniently and eilectively be embodied, l am, aware that many modilications may be made therein within the spirit of the invention as expressed in the claims. Therefore, l do not wish to be limited to the particular forms illustrated, but

That l do claim is:

l. The combination with a printing meinber having relief and intaglio printing surfaces, the relief printing surfaces being higher than the intaglio printing surfaces, of separate means for inlring each of said surfaces, the means for inling the intaglio surfaces being bodily movable toward and from the printing member and the means for inking the relief surfaces being` stationary.

E?. ln a printing machine, the combination of a cylinder, relief and intaglio plates upon said cylinder, and separate inling devices for said plates, one of said inlting devices being bodily movable toward and from the cylinder and the other stationary.

3. .ln a printing machine, the combination of a printing cylinder, a relief plate and an intaglio plate thereon, an inliing device for the relief plate, an inlring device and cleaner for the intaglio plate, and means for bodily moving the inlring device and cleaner for the intaglio plate toward the cylinder when the intaglio plate approaches said inking device, and away from the axis of the cylin der when the intaglio plate passes beyond it.

4, ln a printing machine, the combination of a printing cylinder, an intaglio plate thereon, an inling device and cleaner for the intaglio plate, and means for bodily moving the inliing device and cleaner for the intaglio plate toward and from the cylinder, periodically during each revolution thereof.

5. -ln a printing machine, the combination of a printing cylinder, a relief plate and an intaglio plate thereon, said plates each occupying substantially a third of the surface of the cylinder, the other third being reduced. in diameter', a bodily movable inling device for one of the plates, a stationary inking device for the other plate, and an impression cylinder geared to make three revolutions to one revolution of the printing cylinder.

ln testimony whereof l have hereunto set my hand, in the presence of two subscribing witnesses.
