PROVISIONAL SPECIFICATION.
Improvements in Wood Cutting Tools.
I, ESAU SMITH, of Hunters Road, Hockley, in the City of Birmingham, Builder,
do hereby declare the nature of this invention to be as follows:-
This invention relates to the manner in which I construct a cutting tool for use
in producing moulded timber frames, window sash stops, finials, and other curved
or peculiar shaped moulds, whereby I am enabled to produce the desired moulded
or curvilinear shape in an expetitious and simple manner.
In carrying my invention into effect when constructing a tool for attachment to
any ordinary form of mortising machine, and for producing a clean double curved
cut with the one tool, I make the tool with its stem or attachment end of any
regular form, from ordinary steel bar or from other material, and I form suitable
holes or other attachment devices within this stem for fitting the studs, or other
portions of the slide of the machine. The cutting portions of the tool I make with
à double curved surface to suit the desired curve which is to be produced upon the
timber or frame. The form of the tool so far as the cutting edge is concerned I
vary as may be required, but the angle of the cutting surface in relation to the
stem or stalk of the tool I make of a definite character in order that the outer
surface of the blade may not meet the material which is to be cut all at once, but
may meet it gradually by reason of the angle or inclination of the cutting surface.
The angle I prefer to employ is one approaching 45 degrees to the stein, although
a lesser or greater angle will produce a result very far superior to that possible
with a straight or parallel cutting tool.
I do not limit the application of my invention to any particular curve or shape
of tool, neither do I limit the application of my improved tool, to any particular
purpose but I modify the shape of the tool and the configuration of the cutting
surface to suit any particular requirement taking care only to have the angle of the
cutting surface or blade maintained.

Improvements in Wood Cutting Tools.
I, ESAU SMITH, of Hunters Road, Hockley, in the City of Birmingham, Builder,
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 the manner in which I construct a cutting tool for use
in producing moulded timber frames, window sash stops, finials, and other curved
or peculiar shaped moulds, whereby I am enabled to produce the desired moulded
or curvilinear shape in an expeditious and simple manner.
In carrying my invention into effect when constructing a tool for attachment to
any ordinary form of mortising machine, and for producing a clean double curved
cut with the one tool, I make the tool with its stem or attachment end of any
regular form, from ordinary iron or steel bar or from other material, and I form

page_text: suitable holes or other attachment devices within this s:em for fitting the studs, or
other portions of the slide of the machine. The cutting portions of the tool I
make with a double curved surface to suit the desired curve which is to be produced
upon the timber or frame. The form of the tool so far as the cutting edge is
concerned I vary as may be required, but the angle of the cutting surface_in
relation to the stem or stalk of the tool I make of a definite character in order
that the outer surface of the blade may not meet the material which is to be cut
all at once, but may meet it gradually by reason of the angle or inclination of the
cutting surface. The angle I prefer to employ is one approaching 45 degrees to
the stem, although a lesser or greater angle will produce a result very far superior
to that possible with a straight or parallel cutting tool.
In order that my invention and the method of carrying the same into effect may
be the more readily understood, I append hereunto one sheet of explanatory
drawings to be hereinafter referred to.
Figure 1 is an elevation representing one form of my improved cutting tool,
Figure 2 being an end view showing the shape or form of the cutting edge.
Figures 3 and 4 and Figures 5 and 6 are similar views showing my tools with
modified forms of cutting or working edges.
Figure 7 is a sectional elevation showing one method of attaching the steel blade
or cutter to the stem of the tool.
The same reference letters in the different views represent similar parts.
A is the stem of wrought iron, steel, or other material, having its free end
formed suitably for attachment to the slide or moving arm of a mortising or other
wood working machine. The cutter or blade B is of steel secured to the stem by
screws such as C C₁ or by other suitable and well known method of attachment.
I sometimes forge the blade and stem in one piece, or weld the blade or cutter
to the stem.
I vary the shape of the cutting edge to suit the varying curvilinear form that I
wish to produce upon the material to be operated upon with my improved tools.
But in whatever form I make the cuttting edge I invariably give it an inclination,
preferably as near 45 degrees as possible, in order that it may meet the material
gradually and SO cut it away smoothly. Such an inclination is shown in
Figures 1, 3 and 5.
I do not limit the application of my invention to any particular curve or shape
of tool, neither do I limit the application of my improved tool to any particular
purpose but I modify the shape of the tool and the configuration of the cutting
surface to suit any particular requirement taking care only to have the angle of
the cutting surface or blade maintained.
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 construction of cutting tools for producing curvilinear mouldings in which
the edge of the cutter is inclined so as to permit the cutting to be accomplished
gradually, substantially as hereinbefore described and as illustrated in the
accompanying drawings.
2. The construction of cutting tools for producing mouldings and for like
purposes in which the cutter is formed upon or attached to a holder or stem,
substantially as and for the purposes hereinbefore described, and as illustrated in
the accompanying drawings.
