' To all whom/ it may concern:

- Be it known that I, PAUL VICTOR AVRIL, engineer, a citizen of the French Republic, residing at'Paris, France, (and having my post-office address No. 55 Quai des Grands Augustins, in said city,) have invented certain new and useful Improvementsin Embossing andPrinting Machines, of which the following is a specification. IO This invention has for its object to provide a machine for simultaneously embossing or stamping and printing in one color or several colors ribbons, stuffs, velvet, leather, paper, wire-gauze, sheet metal, and the like. The I5 printed parts of the embossed or stamped material may have each a uniform color or shade, or various shades may be produced either by the superposition of the same color in various intensities or by the superposition of different colors. 5

The essential feature of my invention is to avoid any deformation of the stamped material while being stamped and printed,'this result being obtained by providing the ma- :5 chine with a single cou nterpart or impression cylinder, around which the several printing and stamping cylinders are arranged, so that both stamping and printing is completed on the material before it leaves the said counterpart cylinder. By this method no deformation of the stamped material is possible while passing from one printingcylinder to the other, being always perfectly guided by the sunken and raised parts of the counterpart cylinder.

In order that my invention may be fully understood, I will proceed to describe it with reference to the annexed drawings, of which- Figure 1 is a diagrammatic view of a ma- 4o 1 for embossing materials and printing them with, say, four colors superposed. Figs. 2 and 3 are-two modified forms of this inven tion. Fig. 4 is a front view of two embossingcylinders, showing the form of the engraving thereon.

The principle of my said invention is clearly shown in Fig. 1, from which it is seen that the material 0 to be embossed and printed gasses around a single counterpart cylinder about which are arranged several embossing and printing cylinders a aa. The emchine according to this invention arranged bossing-cyliuder a may be of any suitable material or composition which may be engraved in intaglio or in relief andwhich is capable of' withstanding the pressure required for embossing the material. The counterpart or impression cylinder b may consist of the same material as the cylinder a and have a diameter equal to that of embossing-cylim der or a multiple or fraction of the same.

The material is passed first between the embossingcylinder 0. and the counterpart cylinder b, Fig. 1, whereby the 7 material is embossed and printed for the first time. For printing on raised parts of the embossed material the embossing-cylinder a receives in its sunken parts 1 2 3 4, Fig. 1, the colors to be deposited on the raised parts of the embossed material during the embossing operation. These colors are applied on the sunken parts .of the cylinder a by the raised parts of an ink-transferring cylinder d. These raised parts are seen at 1 2 3' 4, Fig. 1. This inktransferring cylinder d,'thediameterof which may be equal to or a multiple'or a fraction of that of the engraved embossing-cylinder a, receives on its projecting parts the diflerent colors to be deposited on the projecting parts of the embossed material. These colors are transferred onto the raised parts of the cylinder d by means of projecting parts provided on inking-rollers e'e e e, the diameters of which are the same as those of the engraved embossing-cylinder 0.. These projecting parts are seen at 1" 2 3" 4.", Fig. 1. Each of said inking-rollers receives ink from any suitable inking device, which has not been shown in the accompanyingdrawings, and each of them receives but a single color-say e, blue; e, green; a, red, and a yellow.

As the diiferent cylinders rotate in-the direction of the arrows, it is easily understood how the four colors may be deposited and superposed on the sunken parts of the embosslug-cylinder a, from which the said colors are I deposited onto the raised parts of the embossed material while being embossed in its passage between the embossing-cylinder and the counterpart or impression cylinder b. The material having now been embossed and having received its first impression remains in contact withfthe counterpart or impression cylinder b until it has received asecond IOO impression from the cylinder a. In this manner the embossed material cannot take any deformation. The cylinder 0. is inked from a counterpart ink-transferring cylinder d, similar to the cylinder (1, and which receives the color from a series of inking-rollers f f f similar to the rollers e e e 2.

Fig. 1 shows that the embossed'material may receive three successive printings by providing two additional printing-cylinders, the first printing being effected by the cylinder a while the material is being embossed, the second printing while the embossed material passes between the cylinder b and one of the additional printing-cylinders, and the third printing by passing the material between the said impressiomcylinder b and the other additional printing-cylinder. The cylinder a? is provided with an inking device similar to that of the cylinders a and a.

By increasing the number of the cylinders a a a and, if necessary, the diameter of the counterpart cylinder b it is possible to secure any required 11 umber of successive printings. Instead of the additional printing-cylindersn at being engraved they may be smooth and the ink-transferring cylinders may be plain and made of any material capable of receiving the colors and transferring them onto the embossed material. One or more of the printing-cylinders aa' on may be dispensed with and the impression be given directly by the corresponding ink-trans- 'ferring cylinder (1'. Fig. 2 shows this arrangement for the impression of raised parts and Fig. 3 an arrangement for the impression of sunken parts. The ink-distributing cylinders d d, 850., Figs. 1 to 3, may be inked either on the raised parts or on the sunken parts, or on both. If it be desired to superpose bymeans of successive printings different colors or the same colors in various intensities he inking-rollers by which ink is supplied to the ink-transferring cylinders must for this purpose each receive a different color or the same color in various intensities.

The cylinders between which the material to be embossed or stamped is passed may be providcd'with a cutting device for cutting or trimming the edges of the material either in a straight direction or so as to produce wavy or ornamental edges. For example, I have illustrated in Fig. 4 the engraved cylinder (I. provided with cutting edges t, which penetrate into the corresponding grooves j of the cylinder 12 and cut the material to be embossed, following the lines of the design to be obtained.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In a machine for simultaneously embossing and printing in several colors, a central cylinder around which the material operated upon passes, the said cylinder having raised and depressed portions thereon, apluralityof cylinders arranged about said central cylinder having counterpart raised and depressed portions thereon, and separate inking mechanism for the outer cylinders, the raised and depressed portions of said outer cylinders registering with the depressed and raised portions of the central cylinder, and cooperating with said central cylinder to simultaneously emboss and impress in superposed colors on thematerial operated upon while said material remains on said central cylinder.

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

PAUL VICTOR AVRIL.
