IMPROVEMENTS IN ERASING KNIVES
Year: 1884

page_text: I, WILLIAM STEEN of 54 Fitzroy Avenue Belfast in the County of Antrim,
Barrister at Law do hereby declare the nature of my invention for IMPROVEMENTS
IN ERASING KNIVES to be as follows:-
The handle of the Erasing Knife, I propose to make of glass, porcelain, ivory or
other hard substance capable of taking a smooth polished surface. That part of
the handle which is furthest from the blade I propose to form for a short distance
along it on one side slightly convex and rounded off at the extremity and with a
smooth polished surface which being rubbed for a short time lightly & quickly over
the surface of the paper to which the blade has been applied and which has been
thereby cut up and roughened and made unsuitable for writing on will render it
again smooth and suitable to write on; the other side of the handle (that is to say
the side opposite to this convex surface) I propose to form for a short distance from
the extremity furthest from the blade slightly concave so that when the convex
surface is placed on the paper the concave surface may be perpendicularly above it
and thus admit of the finger being firmly placed in the hollow to steady the handle
and give the hand a firm hold of it while smoothing the roughened surface of the
paper.
The feature of novelty claimed as my invention is combining with an ordinary
erasing knife a handle formed as above described to act as a convenent paper
smoother.

DILCIFICATION.
I WILLIAM STEEN of 54 Fitzroy Avenue, Belfast in the County of Antrim
Barrister at Law do hereby declare the nature of my invention for IMPROVEMENTS
IN ERASING KNIVES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement :-
The handle of the erasing knife I propose to make of glass porcelain ivory or
other hard substance capable of taking a smooth polished surface; the part of the
handle furthest from the blade I propose to form for a short distance along it on
one side slightly convex and rounded off at the extremity and with a smooth
polished surface which being rubbed for a short time lightly and quickly over the
surface of the paper to which the blade of the knife has been applied and which
has been thereby roughened and rendered unsuitable for writing on will render it
again smooth and suitable to write on the other side of the handle (that is to say
the side of it opposite this convex surface) I propose to form for a short distance
from the extremity furthest from the blade slightly concave so that when the
convex surface is placed on the paper the concave surface may be perpendicularly
above it and thus admit of the forefinger being firmly placed in the hollow to
steady the handle and give the hand a firm hold of it while smoothing the
roughened surface of the paper.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is the combining with an ordinary erasing knife in the manner hereinbefore
set forth a handle formed as herein before described which will act as a convenient
paper smoother.
