Sharpening Slate and other Pencils.
We WILLIAM JONES of 143 Clopton Street, Hulme in the City of Manchester,
Painter and THOMAS SHEFFIELD of 33 Great Western Street, Moss Side near the City
of Manchester aforesaid, Decorator, do hereby declare the nature of our invention to
be as follows:-
1
The object of this invention is the construction of a receptacle for containing slate
and other pencils and part of which is prepared as a roughened surface for sharpening
the pencil.
In performing our invention we prefer to construct the receptacle of sheet metal
and approximating in form to a spectacle case so as to be conveniently carried in the
pocket, but it is obvious that it may be of cylindrical, tubular, rectangular or other
form and may also be constructed of wood, paper or other suitable material.
The roughened sharpening surface may be composed of perforated sheet metal, the
edges of the perforations forming the cutting surface, after the manner of making nut-
meg graters, or it may be a file surface or other suitable surface with a cutting edge
for sharpening the pencil by rubbing the point of the pencil to and fro in contact
therewith.
This invention affords facilities for applying the cutting or sharpening surface to the
lid or other part of the wooden boxes now employed for containing slate or other
pencils and in this case the wooden lid may be substituted by a sheet metal lid, part of
the surface of which is prepared with a sharpening or cutting surface as aforesaid.

Sharpening Slate and other Pencils.
We, WILLIAM JONES of 143 Clopton Street, Hulme, in the City of Manchester,
Painter, and THOMAS SHEFFIELD of 33 Great Western Street, Moss Side, near the
City of Manchester aforesaid, Decorator, do hereby declare the nature of our invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of this invention is the construction of a receptacle for containing slate
and other pencils and part of which is prepared as a roughened surface for sharpening
the pencil.
On the accompanying drawing Fig. 1. is a front view, Fig. 2. a side view, Fig. 3. a
back view, and Fig. 4. a transverse sectional view of a sheet metal casing embracing
our improvements and shewing a cheap and effective method of carrying out our
invention.
It will be observed that the sheet metal casing a. which is by preference jointed
together at the back by an over-lapped joint b. and without soldering, approximates in
external form to a flat spectacle case so as to be conveniently carried in the pocket. It
is turned down and enclosed at one extremity and at the other is provided with a
hinged lid c.
In front of this casing a part of the surface d. is roughened or perforated after the
manner of making nut-meg graters and thus forms a suitable surface with a cutting
edge for sharpening the pencil by rubbing the point thereof to and fro upon such
surface.
In this manner we construct the most convenient form of our improved apparatus
but it will be obvious that it may be of cylindrical, tubular, rectangular or other form
and may also be constructed of wood, paper or other suitable material and provided
with a sheet metal surface roughened or perforated as aforesaid, or with a file surface
or other suitable surface with a cutting edge for sharpening the pencil.
This invention affords facilities for applying the cutting or sharpening surface to
the lid or other part of the wooden boxes now employed for containing slate or other
pencils and in this case the wooden lid may be substituted by a sheet metal lid, part of
the surface of which is prepared with a sharpening or cutting surface as aforesaid.
Having thus particularly described and ascertained the nature of this our said
invention together with the best methods with which we are acquainted for carrying

page_text: the same into practical effect, we wish it to be distinctly understood that we do not
confine ourselves to the precise details, relative proportions or dimensions of our
improved apparatus hereinbefore described and illustrated on the accompanying
drawing as the same may be considerably varied without departing from our
invention and we hereby declare that what we claim is :-
1st. The improvement in receptacles or apparatus for containing and sharpening
slate and other pencils substantially as hereinbefore described.
2nd. The combination of a receptacle and pencil sharpener substantially as herein-
before described.
3rd. The improved application of a cutting or sharpening surface to the lid or other
part of slate or other pencil receptacle substantially as herein before described.
4th. The improved sheet metal casing provided with a sharpening surface
substantially as and for the purposes hereinbefore described and illustrated on the
accompanying drawing.
