Complete Specification Accepted, 19th Oct., 1888
I, HERBERT JOHN HADDAN, of the firm of Herbert & Co., Patent Agents, of
18 Buckingham Street, Strand, London, in the County of Middlesex, Civil Engineer,
do hereby declare the nature of this invention a communication to me from abroad by
Horace Guarracino, of Constantinople, in the Ottoman Empire, Gentleman, to be as
follows:-
This invention relates to rulers and consists in certain improvements therein whereby
lines etc., may be ruled for instance, over recently written matter without blotting or
soiling the book or paper with ink.
The improvements consist in so constructing the ruler that the material of which it
is composed or covered shall be capable of soaking up ink. For this purpose on
suitable rollers or rods of wood or other material of cylindrical or other convenient
shape are wound sheets of paper capable of absorbing ink such as ordinary blotting
paper, said sheets being so wound that the outer sheet may be easily removed when
soiled without impairing the straightness of the ruler. The improved rulers may be
made without the internal roller if desired, they may likewise be made flat or square
by suitable compression of the blotting paper by hydraulic or other means in suitable
metal frames or without such frames.

Improvements in Rulers.
I, HERBERT JOHN HADDAN of the firm of Herbert & Co., Patent Agents, of
18 Buckingham Street, Strand, W.C. London, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to me
from abroad by Horace Guarracino of Constantinople, in the Ottoman Empire,
Gentleman, and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This invention relates to rulers and consists in certain improvements therein whereby
they are provided with an ink absorbing surface so that lines etc., may be ruled,
for instance over recently written matter, without blotting or soiling the book or paper
with ink.
The improvements consist in so constructing the ruler that the material of which
it is composed or covered shall be capable of soaking up ink. For this purpose on
suitable rollers or rods of wood or other material of cylindrical or other convenient
shape are wound sheets of paper capable of absorbing ink, such as ordinary blotting
paper, said sheets being so wound that the outer sheet may be easily removed when
soiled, without impairing the straightness of the ruler. The improved rulers may
be made without the internal roller if desired, they may likewise be made flat or
square by suitable compression of the blotting paper by hydraulic or other means
in suitable metal frames or without such frames.
Advertisements may be printed on the rulers, for instance on each sheet of
blotting paper forming the covering thereof.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. A ruler having a surface capable of absorbing ink.
2. A ruler having a series of removable layers of blotting paper forming the
surface thereof, substantially as and for the purpose set forth.
