FRED BYRON of Chesterfield in the County of Derbyshire IMPROVEMENTS IN
PENCIL POINT PROTECTORS
This invention relates to improvements in pencil point protectors, and it consists
chiefly in the combination of a blade with the tubular protector for the point of
the pencil, and also in an arrangement for protecting the india rubber at the
opposite end of the protector.
I prefer to make the improved protector of sheet steel, a portion being sufficiently
broad to be turned over to form a tube, to fit upon the pencil, and a narrow piece
shaped to form a blade, and afterwards hardened and sharpened so as to cut.
The tubular part I leave long enough to form a handle to hold it by when using it
to sharpen the point of the pencil, or for other similar purposes, and I prefer to
make the blade of the same curve as that of the tube, that is to say the side
of the blade that lays against the pencil is concave and the outer side is
convex
Instead of making the combined protector and blade from flat sheet steel, I may
if desirable make it direct from steel tubing.
To protect the indiarubber so generally combined with point protectors, I fix it
inside a short piece of tube made to fit and slide within tho outer tube, so that
it can be pushed out or drawn in by means of a small stud projecting through a
slot in the outer tube.
A Cap may be used to fit tightly over the end of the protector, effectually
closing up the rubber, but this is not essential.-Instead of the blade being exposed
(as before described) it may be made to slide within the outer tubing of the
protector.

"IMPROVEMENTS IN PENCIL POINT PROTECTORS
"
The Invention relates to Improvements in Pencil Point Protectors and it
consists,
Firstly, in the combination with the tubular protector of a blade, either fixed or
moveable, which may be used for sharpening pencils, for erasing ink, cutting
string, and for many other purposes; and which may be made with two cutting
edges so that either a right or left handed man may be able to use it.
Secondly, in the combination with the tubular protector of a spring, so arranged
that any sized pencil will fit the protector.
Thirdly, in an arrangement for protecting the India rubber at the end of the
protector
At
My Protector may be made of any suitable material but I prefer steel. The
blade and spring, which may be formed out of the same piece of steel, which forms
the tube, are at one end of the protector; while at the opposite end a small grove
is cut, up which a stud attached to a ring which holds the indiarubber is allowed
to slide, and in this manner the india rubber may be drawn up into the tube.
the end of the protector containing the india rubber a cap may be fitted so as
effectually to close it up, and protect the india rubber; but this is not essential-
It is not necessary to my invention that the blade should be made of one piece
with the protector, but a grove may be cut in the tube, in which two small studs
to which a separate blade is attached may slide, and in this manner the blade may
be drawn into the protector.
My Protector may be made of sheet steel a portion being of sufficient width to
be turned round to form the tube; with a narrower piece at one end to form the
blade, this latter piece being afterwards shaped to the required form and hardened
and sharpened: but if preferred it may be made direct from a piece of tube,
shaped so as to form the protector, blade, and spring; in either case the spring is
formed by cutting a lip in the steel or other material used, and giving it a slight
set inwards so that it may grasp and hold a pencil of various sizes when it is
inserted; and in either case at the opposite end, the slot is cut for the stud to slide
in, which is attached to the ring which holds the india rubber
I prefer to make the blade to the same curve as the tubular protector in order
that it may lay close against the pencil, thus the inner side will be concave and
the outer side convex..
Referring to the accompanying drawing; Figure 1 represents the protector in
section and Figure 3 is an outside view of the same, Figures 2 and 4 are plans of
Figures 1 and 3 respectively. Figure 5 is a view of the material from which the
protector is to be made, cut to the required shape before bending to form the tube,
and Figure 6 is a plan of the same. Figure 7 is a view of the protector which
shows the india rubber drawn up into the tube and thus protected-Figures 1. 2
and 7 show the protector as being made out of a tube, while Figures 3. 4. 5 and 6
all represent it as being made from sheet steel or other suitable material. Figure 10
shows a view of the material from which the protector tube is to be made, before
bending, with the blade (which is shown pushed right back) made separately and
arranged to slide in and out by means of two studs, which are guided in a slot as
shown. Figure 11. is also a view showing the blade (which is shown pushed fully
out) made from a separate piece of material and arranged to slide as above

page_text: described, but in this case the protector tube is shown as being made direct from
a piece of tube instead of from some suitable material which has to be afterwards
bent Figure 8 is a perspective view of the protector, with its lower end cut away,
and with a pencil introduced, and Figure 9 is its cap.
In all the figures where the blade is shown it is represented by the letter A, the
protector tube by the letter B, the spring by the letter c, and the india rubber by
the letter D, while the letter E represents the cap for protecting the india rubber
and the letter F the pencil-G is the slot up which the stud for moving the
india rubber slides; and in Figures 10 and 11 H is the slot which guides the studs
attached to the moveable blade and by which it is moved in and out
Having now described the nature of my invention and the method by which
I propose to carry it into effect, I hereby declare that what I consider to be
novel and desire to protect under the herein before in part recited Letters
Patent is,
First, the combination of a blade either fixed or moveable with a tubular pencil
point protector substantially as and for the purposes described.
Second, the combination of a spring with a tubular pencil point protector,
substantially as and for the purposes described.
Third, The combination with a tubular pencil point protector, of a case containing
indiarubber, which can be pushed up into the tube substantially as and for the
purposes described.
In witness whereof, I the said Fred Byron have hereunto set my Hand
and Seal this first day of December in the year of our Lord one thousand
eight hundred and eighty three
