WRITING-PAPER.

SPECIFICATION forming part of Letters Patent No. 663,513, dated December 11, 1900.

Application filed March 8, 1900- Serial No. 7.369. (No specimens.)

To all whom, it may concern.-

Be it known that I, FRIEDRICH GUSTAV JULIUS POST, a subject of the German Emperor, and a resident of Hamburg, in the German Empire, have invented a certain new and useful Improvement in Writing-Paper, of which the following is a specification.

In the production of copies of writings or prints with the aid of moistened copyingpaper Wound in rolls it has proved expedient to indicate on the copying-paper the boundaries or single edges of the sheets of paper containing the writing or print to be reproduced in order to facilitate the proper severing or trimming, respectively, of the single leaves or sheets and to secure a certain uniformity in the size of the copies. I attain this object by providing entirely or partially one or more edges of the writing-paper with a color capable of being press-copied in such a manner that on passing the manuscript writingpaper, together with the moistened copying'paper, through a copying-press the colored edges of the manuscript will leave impressions on the copying-paper which indicate in the shape of full or broken lines the bonndaries of the man uscript-paper. The color is applied to the edges of the paper in a manner similar to that of producing colored or sprinkled edges in bookhinding. A pack of folded sheets is held in a press and cut by means of a plow or trimming-machine; and

the trimmed edges of the pack are entirely or partly covered with a copyable color by any well-known means.

In the accompanyingdrawingsIhaveshown by way of example three sheets of paper in accordance with my invention in which the colored edges are represented by hatching.

In Figure l a sheet of paper a is illustrated, the lower edge I) of which being provided with copyable color or ink. Figs. 2 and 3 illustrate sheets a a of paper with two colored edges 1) b and o c, of which those of Fig. 3 are only partially colored.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is

l. A sheet of writing-paper having one or more of its edges colored with a copying-color, whereby the limits of the sheet are indicated on a continuous press-copy sheet, substantially as described.

2. A writing-paper, having one or more of its edges colored with a copying-color at one or more points, whereby the limits of the sheet are indicated on a continuous presscopy sheet, substantially as and for the purpose described.
