To all 'ivhom fit-may concern:

Be it known that 1,; HENRY A. Wren Wool), a citizen of the United States, residing at New York, in the county of lien York and State of New York, have finvented a newcnd useful Relief and Integlio Printing Press, of which the following is e. specificstion.

For the purpose of compensating for differences. in diameter of the intsglio cylinder due to the taking 0d ofthe'surfcce to enable it to receive successive etchings or engravings, means is-provided for permittinge circumferential yielding of this cylinder as a Whole or of the impression cylinder.

Reference is to be had to the accompanying two sheets ofdrswings which constitute a pert of this specification, and illustrate practical ways of carrying out the inventions and in which Figurel is a. longitudinal sectional view of a rotary web press supplied with intaglio printing cylinders, in accordance with this invention.

Intaglio printing cylinders areflnede in the form of copper shells, usually about a half inch thick. As the intsglio printing cylinder and the impression cylinder are run togeth r, and must maintain the same surface velocity, they have had to he accu- As these copper cylinders are quite expensive and as there is a, great loss in reinelting them, I have provided means whereby they can be [used several times, the etched or engraved surfaces being successively removed and a. new design etched or engraved on This results in a. gradual reduction in diameter on the integlio cylinder which therefore increasingly drags upon the impression cylinderegeinst which it Works. While heretofore this has not prevented the repeated use of e cylinder, it has necessitated the abandonment of it with great loss after it has been used three or four times only.

Two ink supplies may, of course, liensed, eech touching its own surface to be supplied, or one that is operable to both; any ordinary construction. of the se ne being employed to produce this result. Referring specifically to the drawings, and first to Fig. 1, it will be seen that e rotery web press is shown as arranged so that the illustrations inc-y ce printed in integlio, and t e pe in relief, as has bee stated shove? ll} will be 0 served that the cylinders a, if}, .0 end (2, representthe ordinary printing; couples of a rotary web press, ,the inner cylinders being the impression cylinders. On each of the printing cylinders a ends? are shown two relief printing plates 6 in accordance with the usual construction. Suithble inking mechanism f is also incicstcd. The Web passes from the web roll g around guide rollers 71, over the impression cylinder 5 in contact with the plates on the printing cylinder (4, then around the impression cylinder 0 in contact with the plates on the printing cylinder (5 in the usual Way, but the relief plates are so constructed that while all the type and other desired p'ortions are in relief as usual, those parts which would ordinarily be provided with a surface for printing illustrations, which it is desired to print in c more artistic way,

In the form indicated in thisfigure, each of the intaglio cylinders is of a diameter equal to one half of that of the relief printing cylinder, and it is, of course, timed to make a complete revolution during a half revolution of the relief cylinder. \Vitli this construction the intaglio design. will he re peated for the two impressions obtained from the relief plates, and, therefore, there will be two sets of imprints which will have the intaglio portion thereof in duplicate and which ordinarily will also have the relief in duplicate, as the two relief plates are normally the same. it is to he noted that the intaglio cylinders are located beneath or at one side of the impression cylinders so that the ink which drips therefrom will not come into contact with the impression cylinders. The intaglio cylinders are supplied with inl: from fountains 0 beneath them, these fountains being in the present instance provided with rollers 39, and cleaning blades or other devices 5 being employed in the usual way. The fountains and cleaning devices are mounted below or at one side of the intaglio cylinders so that the fountains will receive the drip therefrom and no ink will be. discharged on the impres sion cylinders. A preferable position. is to ave the intaglio cylinders below the centerof the impression cylinders and their inking devices below the centers of the intaglio cylindcrs. In order that each of the int-aglio cylinders and m may be replaced by a cylinder of a different diameter, the -l'ountains 0 are made adjustable and with them the rolls p and cleaning devices 9. As shown in Fig. 1, they are mounted on a frame? and can he moved up and down in slots 8 therein. This figure shows these parts in dotted lines in position to receive a larger intag'lio cylinder la and 1%. Also in this figure, it will be seen that the web passes over the roll it to the left in order that its last printed side, which is usually handsomely illustrated, will he on the outside and when run over the former will not have to come in contact with the roll at the head thereof or with the turning roll, thus better preserving the efi'ect of the printing on this side of the sheet.

In the construction represented in F ig'. 2, an ordinary type of press is provided with a single intaglio cylinder L so that the illustrations will appear on one side of the sheet only. When the circumferential product of the plate cylinder is .to be collected as shown the intaglio cylinder in diameter to the plate cylinder. a so that a separate set of illustrations may be printed upon each half of the cylinder. inder 7c is shown as provided with tube n having two intaglio designs In Fig. 3 is illustrated another press in which a halfsiied intaglio The cylthereon. type of cylinder a" will again engage is made equal in cylinder.

is is shown in connection with an impression cylinder Z2 and in connect-ion with an impression cylinder 0 is shown a full sized intaglio cylinder It". It may be considered that the change from one size intaglio cyl- 7Q inder to the other is only partly accom-' plished in the form shown in this figure.

in other forms, and in fact in any form in which the invention may be embodied, it is preferable that the fountain, the intaglio printing cylinder, and its plate all he removable either endwise or sideivise, so that the press may be run without them, and so that they can he changed as may be desired.

l i, 6 and. 7 illustrate the yielding connection between the inta-glio cylinder and its shaft. The impression cylinder Z) is shown in this invention as fixed to its shaft on which is a gear 6 operating a gear u on a. shaft h on which the intaglio cylinder 71 loosely mounted. The intaglio cylinder is provided. with a lug or stop w adapted to engage a lug or stop .r on the gear u and this is the only "positive connection between the intaglio c ,'linder and its gear. A. spring 3/ of any desired form yieldingly connects these two elements. Now, it will be seen that while the intaglio cylinder runs in contact with the impression cylinder if it is of a smaller diameter than the impression c3 1- inder, or if the latter is not an. exact'multiple of: the intaglio cylinder on account of the turning down of the surface ofthe' intaglio shell, it ill remain in proper registration with the impression cylinder, itslug w gradually drawing away from the lug m. The spring :1] opposes this action but is not strong enough to prevent it. Now, when a gap 2 in the impression cylinder comes into such position'as to relieve the intaglio cylinder from pressure as shown in Fig. 6, the spring will be free to act to return the intaglio cylinder to such position that the two lugs to and and the two cylinders will then be in proper relation with each 11% other, the intaglio cylinder and its gear being in exactly the same relative position as they would be if they were positively connected together. At this time the lugs or stops do form a positive connection between these elements. This will occur twice during each revolution of the impression cylinder and thus permit the use of the cylinder or shell after it' lias been materially turned it originally was A similar operation will take place when the impression cylinder is yieldingly mounted instead of the intagiio In either case the couple may be driven through the plate cylinder gear, o1: through the impression cylinder gear.

Although l have herein shown and de-' scribed a particular relationship among the several cylinders and an adjustable connect ing device, I do not herein claim the same as mentioned original paten pressed in the claims. Therefore, I do not a posit wish to be limited to the particular mechatherewi nism shown, or to the particular types of shaft, a lug on the cyl printing presses referred to, but gage the first named lug to What I do claim is tion i 1.
