1, WILLIAM SCHLUMPF CONRAD, of St. Edwards, St. Edwards Road, Southsea,
Hants, Schoolmaster do hereby declare the nature of this invention to be as
follows:-
An ordinary blotting-book, or a memorandum-book is interleaved with
copying-paper, so that a copy of a letter or memorandum can be obtained almost
instantaneously by using "a slowly-drying ink,” such as described in the Specifica-
tion of Patent 2011 ('90), by blotting the letter on the copying-paper after, or
instead of, the blotting-paper.
Instead of interleaving the letter-paper or blotting-paper, these may be separately
introduced in convenient quantities of one or more quires, the letter-paper preferably
perforated, the copying-paper so fastened that it can be easily renewed.

Improved Means for Copying Documents without Wetting or Press
by Means of a Slowly-drying Ink.
1, WILLIAM SCHLUMPF CONRAD, of St. Edwards, St. Edwards Road, Southsea,
Hants, Schoolmaster do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained in
and by the following statement :—
Ordinary blotting-books, and memorandum-books are interlined with copying-
paper (or tissue-paper), so that a memorandum (copy) of a letter, invoice, bill,
receipt, order, cheque, or any other written document can be obtained almost
instantaneously by using "a slowly-drying ink," such as described in Patent 2011
('90), and blotting the writing on the copying-paper after, or instead of, the blotting-
paper.
Instead of interleaving the blotting-paper or writing-paper (or both) with
copying-paper, each or all may be introduced in convenient lots of more than one
sheet, the writing-paper can be perforated, and cach or all so fastened by an elastic
band, or other means, that they can readily be removed and renewed.
Thus one
or more quires of copying-paper may be stitched, or otherwise kept together, with
one or more sheets of blotting-paper, either outside or among the leaves of copying-
paper, and with or without other cover except the blotting-paper, so as to form a
small blotting-book which serves as a convenient pad to write upon, if loose sheets
of writing-paper be used. Or the writing-paper may be introduced between the
copying-paper, either fastened (perforated) or loose, so as to be in position for
immediate copying.
Two or more of these "copying-blotting-books "may be contained in a folio (with
or without pockets), and an index may be added. Each separate blotting- (copying-)
book is numbered & its pages are lettered, so that correspondents may refer to any
particular letter as 1, A; 4, W &c. &c., and a copy of the same can at once be
Found

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1.) The introduction of copying- (tissue-) paper among blotting-paper, with or
without writing-paper, for the purpose of forming a blotting- and copying-book
combined.
2.) The interleaving of writing-paper with copying-paper, with or without
blotting-paper, for the purpose of obtaining a copy of any written document by
using a "slowly-drying ink" and blotting the writing with copying-paper after, or
instead of the blotting-paper.
