print one or more extra colors, but can in one operatlon perform a cuttlngoperationespecially'when wall paper borders are being run through the-machine.

A still further object resides in the pros vision of means whereby a printing roller and a cutting roller may be substituted readily for each other without disturbing the other parts of the apparatus.

The invention is illustrated in the drawings, of whichv Figure 1 is a side elevation of the machine;

Figure 2 is an enlarged end elevation with a portion broken away showing the means for printing an extra color;

F gure 3 is a section taken through the apparatus'shownin Figure 2; f igure 4 is an elevation showing the wall paper into means for cutting the borders.

. The form of the invention shown in the drawings is a preferred form, although it is understood that modifications in the conin the character of the materials used maybe adopted -without departing from the spirit of the invention as set forth in the appended-claim. "r

In its general aspect the invention includes the addition to a standardwall paper making machine an apparatus which will permit more than the usual number of colors to be placed on the wallpaper during the continuous operation of the machine and which will at the sametime permit the paper tobe cut in borders while being printed. In the standard wall paper. making machine the paper is fed through the machine over the periphery er a large drum around a portion of the periphery of which a series of printingrollers are disposed, and as the paperis passed around the drum each roller 1 applies its design to the paper.- I The drum is ordinarily mounted in a frame and'the printing rollers arepreferably disposed around. the drum to cover slightly less than half its periphery, so that the drum can be lifted out of the frame when desired, especially if the printing rollers have to be repaired or otherwise attended to. By reason of the fact, therefore, that the printing cannot occupy more than half the periphery pf the drum the standard machines have only been able to print a design in twelve colors. By reason of my invention, however, I can print at least thirteen colors and it isipossible to print more, and in some cases it is also possible to print thirteen colors and at the same time out a border in the'one operation of running the paper through the machine;

To achieve this object I preferably mount anadditional printing roller in the path of the paper before it reaches the drum. As a matter of fact, of course, I can dispose an indefinite number of additional printingrollers in the line of the paper before it reaches the drum. Furthermore, after the paper has left the drum I may pass it through additional rollers which can either 'print or cut it. These auxiliary rollers are removably mounted on a frame so that they can be easily withdrawn therefrom for the purpose of replacing a roller. This is especially convenient with'respect to the rollers disposed in the lineof the paper after it leaves the drum, because in this position the rollers can be removed, so that for instance a printing roller may be substituted for a cutting roller. or vice versa.

In the preferred form of the invention shown in the drawings, Figure 1 shows a frame 10 .having a vertical slot 11 in the bottom of which a shaft 12 is disposed. This shaft supports a drum 13 which has at each end of its periphery gears 14. These gears mesh with a plurality of gears such as "15 mounted on suitable shafts such as, 16 supporting the usual printing rollers. It will be noted that there are twelve of these printing rollers such as 17 mounted around the lower half of the drum and with each roller is associated a color-applying belt 18 diplping into a color trough 19. The paper 20 is passed through the machine between the drum 13 and the various rollers 17 and each roller applies its design in the proper color to the paper in the usual manner. The movement of the paper is indicated by the arrows disposed thereon, and at the right of the machine in Figure 1, I dispose an auxiliary frame 21 on which is mounted three gears 22,

I 23 and 24, meshing with each other, the

a belt roller 31. A color applying gear 22 engaging one of the'gears 14 and the ear 23 mounted on a shaft and acting as an idler. An additional gear 22 is arranged adjacent gear 22, said vadditional gear 22 meshing with gear 14 and gear 28. The gear 24 is mounted on a shaft supporting a printing or cutting roller 25 (see F igure3). This printing or, cutting roller 25 bears against a pressure roller 26 suitably mounted in the frame Engaging with the gear 22 is a large gear 28 which in turn meshes with a gear 29 mounted ,on 'a shaft 30 supporting belt 32 passes over this roller and at the otherend connects with a color "roller 33 mounted in a color trough 34L As shown in Figure'2 the roller 31, the printing or cutting roller 25 and'the tension roller 35 are mounted ontshafts', the ends of which are connected to slidable frame members 36 and 37 having tongues 38 engaging with suitable grooves in the main frame so that these three rollers can be drawn out away from the paper 20 and a new set of rollers can be substituted quickly. In other words the printing roller and associated rollers shown in Figure 3 can be readily withdrawn and an identical set of rollers can be substituted therefor, except a cutting roller is provided instead of printing roller 25, so that the paper may be cut or printed at will and this change can be effected with a min imum expenditure of time and labor. As shown in Figure 1, at "the left of the machine before the paper moves on to the drum a set of apparatus is furnished in every way similar to the apparatus shown at the right of Q Q 1 i the drum 1n igure 1. In the operation of the machine the auxiliary apparatus at the left of the drum 1s mimosa a generally employed to print an extra color or design such as is indicated by thenumeral 39 in Figure 2, and the auxiliary apparatus at the right of the drum in Figure 1 is generally employed to out the paper, as shown in Figure 4, wherein the roller 25 is used as a -may be bodily moved out of the frame atany time, a plurality of printing rollers disthis machine posed around the periphery of the drum between which andthe drum the paper to be printed isadapted to be passed, said printing rollers being carried by the frame below the center of the drum when the drum is in functioningposition, auxiliary means above the center of the drum spaced radially therefrom a suflicient distance to allow the drum to pass when moved bodily out of the frame,

said auxiliary means being disposed in the path of the paper before it reaches the drum for printing additional colors and: designs thereon, and auxiliary means in the path of the paper'after it leaves the drum for cutting the papenlongitudinally, said auxiliary means being spaced suificiently from the drum to permit the drum to be removed from said frame.
