I CHARLES LAKEMAN TWEEDALE of Crawshawbooth in the County of Lancaster
Gentleman, do hereby declare the nature of said Invention for IMPROVEMENTS IN
COMBINED PENCIL POINT PROTECTORS AND CUTTERS, to be as follows:-
My improved combined pencil point protector and cutter is formed of a light steel
tube which fits over the pencil and at one end of this tube a cutter is formed by
removing part of the metal and leaving a trough shaped portion the sides of which
are preferably straightened and the edges sharpened by removing some of the metal on
the inside. The cutting edge of the tube is kept normally covered by a suitable
sheath or cap and the pointed end of the pencil when not in use is inserted into the
opposite end of the tube. The cutter may be used to erase or scratch out blots as
well as for sharpening the poncil.

sheath would be required as the sides of the trough portion of

Improvements in Combined Pencil Point Protectors and Cutters.
1 CHARLES LAKEMAN TWEEDALE of Crawshawbooth in the County of Lancaster
Gentleman, do hereby declare the nature of said Invention for IMPROVEMENTS IN
COMBINED PENCIL POINT PROTECTORS AND CUTTERS, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the following
statement:-
My improved combined pencil point protector and cutter is formed of a light steel
tube which fits over the pencil and at one end of this tube a cutter is formed by
removing part of the metal and leaving a trough shaped portion the sides of which
are preferably straightened and the edges sharpened by removing some of the metal
on the inside. The cutting end of the tube is kept normally covered by a suitable
sheath or cap and the pointed end of the pencil when not in use is inserted into the
opposite end of the tube. The cutter may be used to erase or scratch out blots as
well as for sharpening the pencil.
Instead of forming the cutter as described a portion of the metal may be turned
back and sharpened to form a cutting edge for the pencil. In this case no extra
sheath would be required as the sides of the trough portion of the tube would shield
the cutting edge but the cutter as thus arranged could not be employed for erasing
purposes.
In either of the above arrangements instead of making the cutters by sharpening
a portion or portions of the metal of the tube a separate piece or pieces of metal for
the cutting edge may be secured to the tube or protector which might be of any
suitable metal or material; also the protector may be provided with an independent
knife blade or cutter fitted to slide in the tube; or the blade may be fixed and project
beyond the protecting tube and be covered by a cap or sheath when not in use.
And in order that my Invention may be fully understood and readily carried into
effect I will describe the accompanying Sheet of Drawings reference being had to the
figures and letters marked thereon.
Figure 1 is a view of a pencil provided with my improved combined pencil point
protector and cutter the latter made in one piece with the protector and Fig. 2 is a
view of the protector with the cutter sheath detached.
In these views a is the tube which forms the point protector for the pencil b and a
is the cutting edge which in this instance is formed by removing part of the metal of
the tube at one end and slightly flattening the sides by squeezing them together and
then sharpening the edges of the trough shaped portion by removing some of the
metal on the inner side. The cutting edges are kept covered when not in use by the
sheath or cap c; to sharpen the pencil remove the protector a and reverse the sheath c
by placing it on the opposite end of the protector a so that with the blade or cutting
edge a' a point may be readily cut on the pencil.
One advantage obtained by the form of blade made as above described is that when
sharpening a pencil the tendency is to take shallow cuts and thus a fine point can be

page_text: quickly obtained without breaking the lead, whereas when sharpening a pencil with
an ordinary straight knife blade the tendency is to take deep cuts and so to slash
away or break off the lead.
The combined pencil point protector and cutter shown in Fig. 3 is identical with
that illustrated by Figs. 1 and 2 except that the blade a' is in this case made of a
separate piece of metal secured to the tube a.
In the alternative form illustrated by Figs. 4 and 5 the blade or cutting edge a¹ if
formed out of the same piece of metal as the tube a is made by turning back a piece
of the metal and sharpening the edge as shown or a separate blade may be secured to
the tube. The pencil is sharpened by drawing it over the cutting edge a' as shown.
No sheath or cap for the blade is necessary in this form as the sides of the trough
portion of the protector shield the cutting edge.
Fig. 6 represents a slightly modified form of the combined protector and cutter
illustrated by Figs. 1 and 2. In Fig. 6 the blade a¹ is shown made in one piece with
the protector a from one end of which it projects and is covered when not in use by
the sheath or cap c.
Each of the cutters shown may be used for erasing purposes as well as for
sharpening pencils except the form illustrated by Figs. 4 and 5.
Instead of making the cutter in one piece with or secured to the tube the knife
blade or cutter may be fitted and arranged to slide in the protector.
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-
1. The improved combined pencil point protector and cutter consisting essentially
of the tube a and the blade or cutting edge a' provided with a suitable sheath or cap c
when required substantially as and for the purposes herein described and as shown.
2. A combined pencil point protector and cutter constructed and arranged
substantially as and for the purposes herein described and as illustrated by the
Drawings hereunto annexed.
