I EDWARD GARDNER COLTON of the firm of Popplewell Colton & Co of Victoria
Chambers, Southampton Buildings in the county of Middlesex Fellow of the
Institute of Patent Agents do hereby declare the nature of the said invention for
"AN IMPROVED METHOD OF PRODUCING "WATER-LINES" OR "WATERMARKS" ON
PAPER (a communication to me from abroad by C. M. Schmidt of 124 Leipziger-*
strasse Berlin in the Empire of Germany Merchant) and in what manner the same
is to be performed to be particularly described and ascertained in and by the
following statement :-
This Invention has for its object an improved method of producing what are
known as "waterlines" or." watermarks" on paper and differs from those hereto-
fore practised chiefly in that the lines or marks are impressed upon the paper after
it is calendered or printed and is designed to produce a cheaper process of marking
the same.
To this end, the lines letters, words, coats-of-arms, or other devices which are to
form the mark are drawn or marked on thin paper and this is pasted on cardboard
of say 1 in thickness.
m
The drawing or impression is then neatly cut punched or struck out and again
pasted upon cardboard of say 3/m thickness. A thin sheet of paper is lastly
pasted over the lines marks or devices so formed, and the whole submitted to heavy
pressure.
"
The plate thus obtained now serves as a pressing plate for the paper which is to
be "waterlined
**
or watermarked" and this is effected by placing the paper on
the said plate and passing the whole through a calendering machine. The paper is
then lifted off the plate and will be found to be lined or marked.
The plate (or releivo) can be used for producing a considerable number of lines
or marks.
Having now particularly described and ascertained the nature of the said
invention as communicated to me by my foreign correspondent and in what
manner the same is to be performed I declare that what I claim is
Firstly. Producing "waterlines" or "watermarks" on paper by means of a paper
releivo or impression plate substantially as described.
Secondly. The improved method of producing water lines or "water marks"
on paper substantially as described;
