PROVISIONAL SPECIFICATION.
A Tool for Removing Surplus Lead from Leaded Letters or Designs
Inlaid in Stone or like Materials.
I, JOHN TUCKER WILLIAMS of 11 Ffynone Street, Swansea in the County of
Glamorgan, Monumental Sculptor do hereby declare the nature of this invention
to be as follows: :-
This invention relates to a tool for cutting off the surplus lead from letters or
designs in lead inlaid in marble granite, stone or like materials.
In the usual way of beating in lead to form inlaid letters or designs in marble
granite stone or the like there is always a quantity of lead overlapping upon the
surface extending from the letter or design and in order to remove this and give a
definite outline to the letter or design it has been common to cut away a part of
such surplus lead by means of a joiner's chisel and then rub down the remainder,
as in cutting close to the polished surface of the marble or other material carrying
the letter or design there is danger of scratching or otherwise damaging such
surface.
The tool hereinafter described serves to remove the whole of the surplus lead
bringing the level of the letter or design down to that of the polished marble or
other surface without scratching or otherwise damaging the same.
I take a plate about one eighth of an inch thick of bronze or other metal
sufficiently hard to take an edge suitable for cutting the lead and capable of being
polished so as to be moved flatly upon the polished marble or other smooth surface
without scratching or injuring the same. This plate I make preferably with sides
tapering longitudinally and upon one or both of these sides I form a series of teeth
soine what resembling the teeth of a saw but being bevelled to a cutting edge from
the upper side of the plate and set flat with the plate instead of being set out and
in alternately as required for a saw which is to cut a clearance space. These series
of cutters at one or other side of the plate are brought in contact with the
projecting lead by moving the tool about upon the polished surface, an opening
in the plate being made to afford a hold thereon by the fingers while in its flat
position. By this means the surplus lead attacked from the outer sides of the
inlaid letter or design is most rapidly cut away down to the exact level of the
surrounding polished or smooth surface. The narrow end of the tool may be
sharpened in the form of a chisel for trimming down any exceptional quantity so
as to prepare the work for finishing by means of the other cutting edges of the
tool as hereinbefore described.

A Tool for Removing Surplus Lead from Leaded Letters or Designs

I JOHN TUCKER WILLIAMS of 11 Ffynone Street, Swansea in the County of
Glamorgan, Monumental Sculptor 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 :—
This invention relates to a tool for cutting off the surplus lead from letters or
designs in lead inlaid in marble, granite, stone or like materials.

page_text: In the usual way of beating in lead to form inlaid letters or designs in marble,
granite, stone, or the like, there is always a quantity of lead overlapping upon the
surface extending from the letter or design, and in order to remove this and give
a definite outline to the letter or design it has been common to cut away a part of
such surplus lead by means of a joiner's chisel and then rub down the remainder
because in cutting close to the polished surface of the marble or other material
carrying the letter or design there is danger of scratching or otherwise damaging
such surface.
I make a tool as shown in the accompanying drawing in which
Figure 1 is a plan and Figure 2 is a side elevation.
The tool is made from a plate about one eighth of an inch thick of bronze or
other metal sufficiently hard to take an edge suitable for cutting the lead and
capable of being polished so as to be moved flatly upon the polished marble or other
smooth surface without scratching or injuring the same. This plate I make pre-
ferably with sides tapering longitudinally and upon one or both of these sides I form
a series of teeth A somewhat resembling the teeth of a saw but being bevelled to a
cutting edge from the upper side of the plate and set flat with the plate instead of
being set out and in alternately as required for a saw which is to cut a clearance
space. These series of cutters A. at one or other side of the plate are brought in
contact with the projecting lead by moving the tool about upon its polished surface,
an opening B being made to afford a hold thereon by the fingers while in its flat
position. By this means the surplus lead attacked from the outer sides of the
inlaid letter or design is most rapidly cut away, down to the exact level of the
surrounding polished or smooth surface. The narrow end of the tool may be
sharpened in the form of a chisel for trimming down any exceptional quantity so
as to prepare the work for finishing by means of the other cutting edges A of the
tool as hereinbefore described.
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 :-
A tool for removing surplus lead from inlaid lead letters or designs consisting
of a polished plate having a series of cutting edges substantially as described.
