I, GEORGE GRAINGER Press Tool Maker 72 Anglesey Street Lozells near Birming-
ham do hereby declare the nature of this invention to be as follows:-
The Sharpener consists of four cutters and a guide, all made out of one flat piece of
steel. To shew clearly the shape of cutters, and method of sharpening pencils I refer
to drawings:
Fig. 1. A is the guide through the hole of which the pencil B. passes direct to the
cutters C. D. E. The blank is pierced in such a shape as when raised it forms four
cutters, and a guide for the pencil. There are two horizontal, and two vertical cutters.
The horizontal cutters are formed by simply piercing a conical shaped hole out of the
centre of the blank, as shewn in Fig. 3, forming cutters F. E. The vertical cutters
are formed by raising two sides of the blank in such a manner as to form cutters C. D.
The left hand vertical cutter is formed by the left side of the blank being turned
underneath, and the edge brought central with cutter 0, as shown in F 1. D. The
right hand vertical cutter is formed by the right side of the blank being turned over
the top as shewn in Fig. 2. C.
Fig. 3 shews all four cutters, the two horizontal F. E. being formed by the conical
shaped hole, the top and bottom vertical cutters C. D. being formed by being bent over
the top and underneath respectively.
All four cutters form a conical cavity, so that when the pencil is pressed into it
and revolved it must necessarily produce a sharp point.
Declared at Birmingham, in the County of Warwick,
this 12th day of July 1886,
Before me, M. BUTCHER,
A Commissioner to administer Oaths in the
Supreme Court of Judicature.

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:
The sharpener is made out of one flat piece of steel or any other suitable metal. It
consists of four cutters two horizontal and two vertical, also a guide through which
the pencil passes direct to the cutters. The edges of the cutters are so arranged that
they form a conical cavity.
In order to shew the nature of my invention, the shape and position of cutters and
method of sharpening I refer to drawings:-
Fig. I is the shape of a blank cut out and pierced before being turned up or raised
into its final shape. A is a pierced hole forming guide through which pencil B passes
as shewn in Fig. II.
The edges F and E of the conical shaped hole in the centre of the blank form the
two horizontal cutters F and E as shewn in Fig. II.
The outer edges of the wings C and D are slightly tapered from the top. The left
hand wing C is turned over the top, and the edge bent down directly over the centre
of the hole in the middle of the blank, forming the left hand vertical cutter C as shewn
in Fig. II.
up
The right hand wing D is turned underneath and the edge bent directly under
the centre of the hole in the middle of the blank forming the right hand vertical
cutter D as shewn in Fig. II. It will be seen that the four cutters when made and
placed in position as above described form a conical cavity, and when the pencil is
pressed against the edges of the cutters and revolved a sharp point will be produced.
The edges of the four cutters may be bevelled, shaped, or sheared in order to make
them cut better.
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-
An improved pencil sharpener made with four cutters, the cutters being so made and
arranged as to form a conical cavity substantially as hereinbefore described and as
illustrated by accompanying drawings.
