application filed February it, 1907. 'terial No. 357,887.;

To all whom it maycowwem:

Be it known that T, Hanna A. Wren Wool), a citizen of the Unlted States,.res id- 'ing at New York, in the county of New 5 York and State of New York, have invented a new and useful Relief and Tntagl o Print ing Machine, of which the follow ng is a specification. I

In theprinting of photogravures. which to done from etched intaglio plates, the t1tle and any other parts in letter-press are run ordinarily at a separate operation, after'the intaglio print has been made, thus necess1- tating two handlings ofthe, work.

15 The principal objectof this invention is to provide means whereby a machine. at one handling will first print from one set of plates, and thereafter from the other, said plates constituting substantially the same or contiguous surfaces, whereby portions of a picture may be done in intaglio, and other portions super-imposed thereupon in relief, or vice versa. Consequently, a picture may be printed from intaglio surfaces, and the title or surrounding frame or the like printed from relief blocks.

Reference is to be had to the accompanying drawing which is a longitud nal sectional view of a portion of a prlnt ng press 3o showing one form inwhich the invent10n can be carried out.

In this form the machine is provided with a two revolution impression cylinder a, a two-revolution relief plate cylinder 6, and a two-revolution intaglio plate cylinder 0. The relief plates are inked by an inking device 0?, and the intaglio shell by an inking device e having a scraper f of any usual or desired construction.

o The impression and printing cylinders are designed to be separated so as to move into and out of contact. This is accomlished in any desired way, as by mounting ilie shaft ofthe impression cylinder in ee- 5 centric journal boxes 2 provided with levers g operated through connections r in any desired way. By this means the impression cylinder is actuated to rise at each alternate revolution.

5 Itwill be noticed that as in this construction the cylinders make two revolutions to an impression, the printing cylinders would be double inked-if the inking mechanism were not withdrawn during the second revo- M lution of each of the printing plates as shown. The inking mechanisms 03 and e, as. indicated inthe drawing, are mountedin frames 9' and it respectively. These frames being mounted to slide in ways 2' and la, and are actuated to'move toward and from their respective printing cylinders preferabl 1 horizontally. 011 one revolution of the cyl inders they are in contact with their cylinders to ink the" same, but on the next revolutionthey are withdrawn so that the cylinders Wlll not be double inked; that is, inked twicefor eachimpression. It will be under stood that on the second revolution the printing cylinders are not in contact with the sheet on the impression cylinder which is delivering at this time. The specific.

mechanism by which this movement is brought about is relatively unimportant, but I have shown it in the form of gear Z'mounted onthe shaft m of each of the printing shaft n through a gear 0 to' operate the shaft n at half the speed of the shaft m. 0n each shaft n is a cam or the like which operates the frame on which the inking mechanism is mounted once during each revolution of the shaft, which, in the present instance, makes one revolution for two revolutions of the printing cylinder. This con-' struction may be varied to suit conditions impression cylinder between the head of one sheet and tail of the next one for the purpose of gripping and delivering, and when the cylinder has a forward delivery at least one idle revolution is made for every sheet in order to deliver it. lit will be clear, therefore, that by constructing a printing press in'accordance with the principles herein illustrated, the above mentioned advantages will be secured in a simple, convenient and accurate manner.

While ll have illustrated and described only'one form in which the invention can be constructed, ll am aware of the fact that many modifications can be made therein within the spirit of the invention as expressed in the claims. Therefore, I do not cylinders, this gear being connected with a Jill!) wish to be limited to the particular form illustrated, but

What I do claim is L In a sheet printing machine, the combination of an impression cylinder, a relief printing cylinder, a multi-revolution intaglio printing cylinder, and means for inking said printing cylinders only during alternate revolutions thereof.

' 2. In a printing machine, the combination of an impression cylinder, a two revolution relief printing cylinder, :1 two-revolution intaglio printing cylinder, the relief and intaglio printing cylinders contacting with the impression cylinder, and means for inking one of said cylinders during alternate revolutions, said means being inoperative during the remaining revolutions.

3. In a printing machine, the conibinatio of an impression cylinder, two printing cylinders, one carrying a relief printing surface, and the other an intaglio printing surface, an inking device for each cylinder, and means for automatically moving said inking devices toward and from their respective cylinders.

4:. In a printing machine, the combination of an impression cylinder, two two-revolution printing cylinders, inking devices for it during the next revolution.

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