WALL-PAPER-PR INTING MACHINE:

SPECIFICATION forming part of Letters Patent No. 736,043, dated August 11, 190%.

Application filed April 1, 1903.

To all whom, it may concern: V

Be it known that I, JAMES A. WATSON, a citizen of the United States of America, and a resident of Washington, in the District of Oolumbia,have invented certain new and useful Improvements in Wall-Paper-Printing Machines, of which the following is a speci fication.

In printing wall-paper the strip of paper is usually passed first over a grounding-machine, which lays on the ground color, then over a second printing-machine, which prints the pattern, and sometimes over a third printing-machine for laying on lines'or other additional patterns for producing tapestry and other effects. In each printing-machine the paper absorbs a large amount of moisture, and it is the object of the present invention to rapidly dry the paper as it comes from the printing-machine without smearing or blurringthe colors, so that the paper may be immediately taken up by the succeeding machine whether the latter be a second printing-machine or a mechanism for calendering, embossing, or reeling.-

The invention willbo particularly described in the following specification, reference being had to the accompanying drawings, in which-- Figure l is a diagrammatic side elevation showing so much of the wallpaper-printing mechanism as is necessary to illustrate the present invention; and Fig. 2 is a plan view of the same, parts being broken away.

Referring to the drawings, A indicates a primary printing-machine, and B a secondaryprinting-machine. As illustrated,the primary printing-machine is supplied with asingle-color roll 1 for putting on the ground color on the otherwise blank paper, and the secondary printing-machine is supplied with a plurality of pattern-rolls 2 for laying on the patterns in various colors. The blank paper is supplied from a roll 3, being drawn from the roll bya pair of feed-rolls 4 and'delivered upon a slowly-moving belt 5, which forms a reservoir to contain a quantity of slack paper. From the belt 5 the paper passes over tension-rolls 6 and then around the main cylinder ofthe grounding-machine A. After the ground color is laid on the paper passes over guide-rolls 7 8 and then successively Serial No. 150,588. (Nb model.)

around heated drying-rolls 9 10 11 12. These drying rolls are so proportioned and arranged that the back of the paper is in contact with each roll,thus preventing any smear ing of the patterns on the face of the paper. I accomplish this by making the first roll 9 of suitable size, the second 1301110 of less diame ter, the third roll 11 of still less diameter, dtc. Any desired number of rolls may be arranged in this way, the smaller rolls being between the larger rolls. The several drying-rolls preferably have theiraxes in the same plane, as shown in Fig. 1. The dried paper is delivered from the last heating-roll to a point between the rolls and must be taken out laterally. For this purpose I use a pair of an= gularly-arranged rolls 13 14. The roll 13 guides the paper out from between the dry ing-rolls, and the roll ltrestores it to parallelism with the paper running over the drying-rolls. The roll 14 may be omitted if the machine which operates next upon the paper be arranged at right angles to the printing machine.

When the machines are in tandem, the ar rangement shown in Figs. 1 and 2 may be used. The paper is drawn from the roll 14: by feedrolls l5 and delivered upon a slowly-moving belt 16 or other device for accumulating a quantity of slack paper. From the accumulator 16 the paper passes to the next machine. As shown, it passes over a second series of tension-rolls 17 and over the multicolor-print ing machine B, which prints the pattern. A series of drying-rolls, such as those'following the primary printing-machine,may be applied to dry the paper as it comes from the secondary printing-machine.

It will be evident that drying-rolls arranged as illustrated and described herein may be used with any printingmachine for drying continuous strips of paper or other fabric. I do not, therefore, limit the presentinvention to the particular combination and arrangement of elements illustrated. The invention, however, is especially adapted for wall-paperprinting mechanism. In this class of print: ing the paper runs very rapidly, and it must be rapidly dried in order to save time and 10) floor-space.

Having described my invention, what I claim, and desire to secure byLetters Patent, 15-- 1. In a Wallpaper-printing apparatus, the combination of a primary printing-machine, aseries of drying-rolls consecutively decreasing in size, the smaller rolls being located between the larger rolls, and a secondary printing-machine, the paper passing successively and continuously over said primary printingmachine, dryingrolls and said secondary printing-machine.

2. In a wall-paper-printing apparatus, the combination of a primary printing-machine, a series of drying-rolls consecutively decreas' ing in size, one or more smaller rolls being located between the larger rolls, a diagonallyarranged roll within said series for guiding the paper laterally and a secondary printingmachiue, the paper passing over said machine and rolls in the order stated.

3. In a wallpaper-printing apparatus, the combination of a primary printing-machine, aseries of drying-rolls operating in succession upon the paper as it comes from the primary printing-machine, said rolls being so constructed and arranged that the backof the paper travelson each roll, an accumulating device or reservoir receiving the paper from said drying-rolls, and a secondary printingmachine receiving the paper from said accumulating device or reservoir.

4:. In a Wallpaper-printing apparatus, the combination of a primary printingmachine, a series of drying-rolls having their axes in a com mon plane,said rolls successively decreasing in size and the smaller rolls being located between the larger rolls, a diagonal guideroll between the rolls of said series, and a secondary printing-machine, said machines and rolls operating consecutively upon the paper in the order named.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES A. WATSON.
