My Invention has for its object, an improved method and apparatus, for
cutting and pointing the ends of lead pencils the same consisting of an inner and
outer casing, being so formed as to be constantly attached to the end of the pencil,
without impedeing its use, and the same consists of the following features
First. A peculiar construction and arrangement of parts in the formation of an
inner casing, the same to consist of a circular plate of steel or other material equivalent
thereto, so arranged at the parts which shall form the point of the pencil with a series
of prepared cutting edges, set to follow in rotation with each other, so that the cedar
wood or other material may be cut and pointed in seperate stages, by the revolving
action of the pencil upon the cutters.
Secondly. The formation and construction upon the inner circular sheet of steel of
a suitably chased thread, so that by holding the cutter, and rotating the pencil, it can
travel proportionally against the prepared series of cutting edges.
Thirdly. The employment in combination of a circular outer casing, so formed as
to strengthen, the inner casing of sheet steel, when cutting and pointing the pencil,
having openings so arranged in its outer periphery (but opposite to the inner cutting
edges) for the discharge of the cuttings.
Fourthly. The combination and construction of Lead pencils, so that upon their
outer periphery, a chased thread may be formed, of such a size and pitch as to
be proportionally equal to the prepared chased thread in the inner casing of sheet
steel.
And that the same may be more fully understood and readily carried into practical

I WILLIAM BRACEWELL of Brinscall near Chorley in the county of Lancaster
Engineer 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, that is to say :-
My invention has for its object the better carrying out by mechanical and other
means, the process of sharpening the points of pencils, the same consisting of a
Tubular casing, having a chased thread formed within itself, being so arranged as to
work in combination with a similarly chased thread upon the pencil, and thereby to
propel the same against the provided cutting parts.
The chased thread also acting to withdraw the pencil and thereby protect the point
of the pencil.
The pointing of the pencil to consist of a single, or a series of tapering and
serpentine cutting edges, so that by rotating the pencil the chased thread will cause
it to travel proportionally, against the prepared cutting edge or points.
Now this my invention consists of the following features :-
First. A peculiar construction and arrangement of parts in the formation of a
Tubular casing of sheet steel, so formed at the tapering part, which constructs the
point of the pencil, with a serpentine cutter, having either a long cutting edge, or a
series of cutting edges set to follow in rotation with each other, being attached to the
tubular casing, at its tapering part, and used either separately or together, in accord-
ance with the material acted upon.
Second. special construction and arrangement in the tubular casing, of a suitably
formed thread, being so made as to act in combination with a chased thread upon
the pencil, when by holding the tubular casing and rotating the pencil, the chased
thread will cause the pencil to travel proportionally against the serpentine cutter or
cutting points.
Third. The employment in combination of an outer Tubular casing, being so formed
as to strengthen the inner casing, when the pencil is being cut or pointed, the
casing having upon its tapering part, suitable openings for the discharge of the
cuttings.
Fourth. The combination and construction of lead and other pencils, so that upon
their outer periphery a chased thread will be formed, proportionally equal to the
thread within the tubular casing.
And in order that this my said invention may be fully understood and readily
carried into practical effect, I will proceed to describe the same, with reference to
the accompanying drawings and to the letters and figures marked thereon.
Similar letters,refer to similar parts throughout the several drawings.
Fig. 1 of the accompanying drawings represents, the longitudinal section of a lead
pencil, showing the tubular casings attached to the end of the pencil.

page_text: The serpentine cutter B being attached to the taper, and point forming part of the
inner casing.
The chased thread upon the periphery of the pencil A, being so formed, as to be
equally proportionate to the thread within the inner tubular casing.
Fig. 2 represents the full view of a pencil, having the outer tubular casing attached
and fixed to the inner casing, so that the cutter B may come directly opposite to the
opening E, for the discharge of the cuttings, when the pencil is being pointed.
Fig. 3. represents an enlarged view of the inner tubular casing, when not attached
to the pencil A, the serpentine cutter B being shown as attached to the taper and
point forming part of the casing. The edges or points of cutter B, being so formed
as to project at an angle towards the centre of the pencil, so as to give the required
keenness to the cutting edge or points.
Fig. 4 represents the outer casing, as being made from sheet steel or other material
equivelant thereto, so formed of that given diameter, as to allow the inner casing to
fit tightly within it, and there secured and revitted to each other, so that the cutter B
may come directly opposite to the opening E. The annular parts on the outer casing,
being formed to strengthen the casings, when pointing the pencil.
Figs. 5 and 6, represent the serpentine cutters B & B¹, when not attached to the
inner casing one view B being shown as representing one long cutting edge.
View B' representing the serpentine cutter with a series of cutting edges or points.
The two cutters being made to act in connection with the inner casing, and thereby
used in accordance with the material acted upon, when under the process of cutting
or pointing the pencil.
Having now particularly described and ascertained the nature of my said invention,
and in what manner the same is to be performed and carried into effect, I declare
that I claim as my invention:—
First. The construction from steel or its equivalent, of a tubular casing, having a
chased thread formed within itself, and made to propel a pencil proportionally against
the provided cutting parts, so as to point it.
Second. The construction and formation of pencils, having upon their outer periphery
a chased thread, suitable for rotation within the chased tubular casing, so as to propel
the pencil.
Third. The combination of an outer casing, made so as to strengthen the inner
casing, when pointing the pencil.
Fourth. The construction and application of serpentine cutters, formed with a
single or a series of cutting parts, being attached to the inner tubular casing, so as to
point the pencil acted upon.
