T Q all'whom t may concern:

` Be it knownthat I,`IIERBERT C. Jarvis, of the city of Toronto, inthe county of York, Province of Ontario, Canada., a'subject lof the King of Great Brita-in, have invented certain new and useful Improvements in the. Manufacture ofWall Paper, of which they which the paper is supported, sothat, if no remedy bejprovided, the color would soon accumulate in such fashion as to interfere with the clean printing of the paper, and my object therefore is to devisemeans for overcomingthis trouble. 1

I attain my object in the manner hereinafter described and illustrated in the accompanyingl drawings in Which- Fig. 1 shows apart of a strip of Wall paper and a printing roller in the act of printing the pattern on the paper, a Wider strip of paper being shownunderlying the strip of Wall paper;

Fig. 2 a plan view of a modified form of a strip of Wall paper produced in accordance with my invention, an underlying strip of paper being shown in connection therewith; and v Fig. 3 a side elevation showing diagrammatically one method of employing the underlying strip -of paper shown in Figs. 1 and 2. h

In the drawings like numerals of reference indicate corresponding parts in the difrent figures.

I aim to make it possible to print Wall papers either Without selvages o-r With only one selvage, and ing manner. Instead of making the print- `ing surface of the printing rollers of the exact Width of one or more repeats of the pattern, I extend the pattern about onequarter inch at each end of the roller, these extensions being partial repeats of the pattern to be printed bythe roller, see Fig. 1.

In printing Wall ypapers Without any selvage, I use a paper of the exact Width of one or more transverse repeats of the patthis I effect in the follown' terny and therefore about` one-half inch narrower than the printing surface ofthe roller. v n

Now, asa-strip of paper can beguided through the printing `nia-chine to Within onequarter inch of exact alinement with; the printing rollers for lengths upy to. `many Yards, and as the paper is the exact Widthv of one or more horizontal repeats of the pattern, the pattern is printed so that one side of the paper will match the other exactly, oner margin being exactly complementary to the other in adjacentstrips-up to thelengths ordinarily cut.

In printing the Wall paper `Withoneselvage only, I use paper about one-half inch Wider than the horizontal tern (see Fig.` 2) and guidev the papery throughy the printing machine so that the edge A*of* the printing surface of the roller Will overlap one edge ofthe paper about one-quarter inch more or less, thusV leaving a selva-ge along the other edge'.

When hanging paper'with one selvage, the edge Without selvage may be laid over the selvage, of the last hungstripand ex` tended over the printed portion to the line Where the pattern exactly lmatches, thus a perfect matching of thel design may be obtained, the selvage being entirely covered.

When Wall paper is printed in the manner described, it is evident that the overlapping printingrollers Will deposit color on the blanket or surface on Which the paper is supported, and that if no remedy be pro-L vided'the color Would soon accumulate in such fashion as to interfere with the vclean printing of the paper. While -the trouble might be overcome by providing wiping devices to remove the color from the blanket, I prefer to run a web of paper under the Wall paper being printed 'which is sufficiently Widerthan the Wall paper to receivethe imprint ofthe overlapping roller-ends. This underlying paper may be dried land used many times over, or if of sufficiently cheap repeat of the. patstock may be rolled up with the Wall paper,

in Which case it would serve toprotect the ends of the roll'from damage, and When the paper is being cut `into strips for hanging, each strip- Will have a blank,

strip underlying it projecting sufficiently at each side to keep the paste usedy in hanging from spreading on to the table or under the edges of thewall papery or onto the edges of un-l derlying strips. y.

`In Fig. l, I show an underlying strip of paper l projecting at each side beyond the sides ci? the strip of Wall paper. r`his is the arrangement which Will be employed When paper is printed Without a selvage, at either side. In F ig. 2, the underlying strip l is shown projecting at one side only, namely, that side which is Without selvage. In Fig. 3, the underlying strip of' paper l is as an endless band passing around rollers 2, which in practice will be spaced suliiciently far apart so that the paper has time to dry before it returns to the printing position.

What l claim as my invention is 1. A process of printing a strip of Wall paper which consists in superimposing the strip of Wall paper on another strip of paper and printing said strip of Wall paper with a printing roller having its printing surface wider than the exposed strip of Wall paper when hung, lthe underlying strip of paper being adapted to receive the imprint of a projecting 'end of the roller.

2. A process of printing a strip ofivall paper which consists in superimposing the strip of wall paper on underlying paper and printing said strip of Wall paper with a printing roller having its printing surface Wider than the exposed strip of Wall paper When hung and projecting beyond the Wall paper at eachy side. the underlying paper receive the imprint of the of the rollers.

3. A process of printing a strip oi Wall paper which consists in superimposing the being adapted to projecting ends shown y strip of Wall paperon another strip of paper and printing said strip of Wall paper With a printing roller having its printing surface wider than theexposed strip of Wall paper when hung, the underlying strip of paper being adapted to receive the imprint of a projecting end of the roller, drying the Wall paper and the underlying paper, and rolling them up together.

4. A process of printing a strip of Wal-l paper with a repeat pattern, which consists in superimposing the strip of Wall paper on another strip of printing lroller formed with a repeat pat.- tern and having its printing surface Wider than the exposed width of the strip of paper when hung and printing said strip with the printing surface overlapping one edge of the strip, the paper being of a width not less than a. suitable repeat of the pattern.

5. A process of printing a strip of Wall paper with a repeat pattern, which consists in superimposing the strip oi? Wall paper on another strip of printing roller formed with a repeat pattern and having its printing surface wider than the exposed width oi' the strip or' paper when hung and printing said strip with the printing surface overlapping both edges of the strip, the paper being of a Widthexactly equa-l to a suitable repeat of the pattern.
