Improvements in and connected with Holders for Pencils, Crayons,
Caustics, and the like.
I, FREDERICK ELIJAH BLAISDELL, of Wayne Junction, in the City of
Philadelphia, County of Philadelphia, State of Pennsylvania, U.S.A., Gentleman,
do hereby declare the nature of my 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 my invention is to provide a pencil having its marking-lead or
crayon enclosed in a covering capable of being removed little by little from the
crayon as the same is worn away by use, without the use of a cutting instrument,
in which the lead or crayon while not secured in any manner to the covering
material cannot easily be drawn or pushed from its covering.
This I accomplish by providing the marking-lead or crayon with a covering-film
of any suitable material which is less lubric than the material of which the marking-
lead or crayon is composed, and enclosing such marking-lead or crayon in a roll
composed of a sheet of flexible material provided with a series of weakened lines
arranged diagonal to the axis of the roll, all as shown and described in the
following Specification of which the accompanying drawing forms a part, wherein
similar letters or numerals of reference designate like or equivalent parts wherever
found throughout the several views, and in which :-
Fig. 1, is a view of one of such non-lubric covered crayons or marking-leads
about to be enclosed in a suitably formed sheet of covering material;
Fig. 2, is a view of a completed pencil of my improved form, showing a section
of the covering material in the process of being stripped from the crayon or
marking-lead;
Fig. 3, is a view of such non-lubric covered marking-lead or crayon in central
longitudinal section thereof as the same appears at one stage of the process of
manufacture thereof; and
Fig. 4, is a view on an enlarged scale of the bottom portion or point section of
such non-lubric covered crayon or marking-lead, as the same appears when
completed and ready for insertion in its covering.
Referring to the drawing:
The reference letter A designates the marking-lead or crayon, B the non-lubric
covering-film of such lead or crayon, C the crayon covering proper, and C¹ the
sheet of flexible material out of which the crayon-covering Cis formed when the
pencil is to be of my improved self-sharpening form.
The sheet C is of parchmentized paper or of ledger paper, is of the same width
as the lead is long, and of sufficient length to form a roll of about the size of an
ordinary lead-pencil when such sheet C₁is rolled tightly around the marking-lead
or crayon A. Running lengthwise of the sheet C¹ is a series of weakened lines 1,
made by creasing or scoring, along which the same may be separated into narrow
strips 2.
It will be seen from an examination of Fig. 1, that the sheet C is of the form
of a parallelogram having two obtuse angles and two acute angled corners, and
such sheet is preferably provided adjacent to the edge which will form the outer
edge of the covering roll with a series of perforations 3, of about the diameter of
one half the width that of the strips 2, and preferably located as shown about half
an inch from the strip C¹ and centrally of the weakened line or scorings 1.

page_text: When the marking-lead or crayon A is formed of a highly lubric substance such
as plumbago, or a mixture of plumbago and other substances, and such crayon is
enclosed in a roll formed of a sheet of flexible material as C', as shown in Fig. 4,
the extreme lubricity of the lead renders it easy to push or pull such lead or crayon
from the enclosing roll. This of course is a great disadvantage in many ways,
especially when the lead or crayon is from any cause broken into short pieces in
the cover, and to overcome this I provide such lead or crayon with a non-lubric
covering B, which may be applied thereto in any desired manner, preferably in the
form of a liquid which will solidify thereon after being applied.
This non-lubric covering-film B is preferably of thin copal varnish applied to
the crayon by dipping and drying the same while in a perpendicular position after
which the bead 6 at the lower end is removed, by immersing the lower end of such
crayon in a bath of turpentine or other solvent of the varnish until dissolved
therefrom.
To form my improved pencil the sheet C¹ is provided with a suitable edging of
some adhesive substance such as glue, paste or the like, applied to such sheet along
the same outside of the line of perforations 3, the marking-lead or crayon so
covered with the non-lubric film B, is placed at the end of the sheet C which is
opposite to that provided with the adhesive material and the line of perforations 3,
and such sheet C¹ is then rolled tightly around such marking-lead or crayon A
into a roll as shown in Fig. 4, and as soon as the end provided with the adhesive
substance comes in contact with the rest of the roll it adheres thereto, and after
being allowed to dry, the pencil is finished by sawing off the superfluous hollow
top portion, and may then if desired be varnished and otherwise ornamented upon
the outside.
When so formed the pencil is from the first provided with a conical pointed
crayon covering C, and as soon as the lead or crayon point extending therefrom is
worn down to such covering, the lowest of the strips 2 adjacent to such point is
started from the roll by tearing the same across adjacent to the first one of the
perforations 3, at the point marked 7 in Fig. 1, starting the same with the finger-
nail, or with a pin-point or other suitable pointed instrument, after which such
strip is easily separated from the roll along the weakened line forming the upper
boundary thereof, by pulling upon the end so loosened, as shown in Fig. 2, and
when such strip is wholly removed from the crayon, it will be found that a section
of the covering in the form of a conical helix has been removed therefrom, and
that a portion of the marking-lead or crayon A equal in length to the width of the
strip 2 removed has been uncovered for use.
The non-lubric covering-film B does not adhere to the paper, but prevents the
crayon from slipping in the covering C, yet at the same time it is so thin as not to
interfere with casy writing, and it wears away as fast as does the lead or crayon
itself, and while as before stated I prefer to use copal varnish therefor such film
may be made of rubber, gelatine, or any other substances, with equal effect.
It will be seen that this pencil differs from others in which the crayon is
provided with a covering-film of glue or other adhesive substances, in that in
the other forms of pencils the covering-film adheres both to the crayon and to the
covering, and in pencils provided with the covering of the form herein shown,
which may be stripped from the crayon section by section, if such film adhered to
the covering as well as to the crayon, such covering could not readily be stripped
from the crayon, as the last layer of the covering being glued tightly to the crayon
would have to be whittled or cut from the crayon before the pencil could he used.
If desired however, even in my improved form of pencil construction herein
shown, the marking-lead or crayon inay have its upper butt, or end furtherest
from the point, glued or otherwise secured to the covering for a short distance,
but in all cases the working portion of the crayon, (by which term of working
portion I mean that portion of the crayon which is adapted to be uncovered and
worn away by use, before the pencil becomes too short for efficient use) is
unattached to the covering sheet C'. Although I prefer, in making a pencil of

page_text: the improved self sharpening form shown, to use parchmentized paper or ledger
paper, to form the crayon covering C, there are many other substances such as
thin wood-veneer, cloth etc., which may be used, and I do not intend to confine
myself to any particular substance either for the covering, or for the marking-lead
or crayon, or for the film B, as it is evident my invention is adapted for use with
all kinds of chalks, crayons, caustics, etc., and in fact any and all substances in the
form of sticks which it is desired to uncover piece by piece, as well as for ordinary
lead pencils.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1. A pencil having its marking-lead or crayon provided with a covering-film B
of less lubricity than the crayon and inclosed in a roll composed of a sheet of
flexible material C₁ weakened at intervals, the film B being unattached to the
sheet C¹ throughout the working length of the crayon, substantially as described
and for the purposes set forth.
2. A pencil having its marking-lead or crayon provided with a covering-film B
of less lubricity than the crayon and inclosed in a covering from which sections in
the form of a conical-helix may be removed one by one so as to uncover the
marking-lead or crayon section by section, the film B being unattached to the
sheet C¹ throughout the working length of the crayon, substantially as described
and for the purposes set forth.
3. A pencil having its marking-lead or crayon provided with a covering-film B
of less lubricity than the crayon and inclosed in a roll composed of a sheet of
flexible material C' bearing weakened lines arranged diagonal to the axis of the
roll along which the sheet may be separated, the film B being unattached to the
sheet, substantially as described and for the purposes set forth.
4. A pencil having its marking-lead or crayon provided with a covering-film B
of less lubricity than the crayon and inclosed in a roll composed of a sheet of
flexible material bearing weakened lines arranged diagonal to the axis of the roll,
along which the sheet may be separated, the outer edge of the sheet being secured
to the roll, and the film B being unattached to the sheet, substantially as described
and for the purposes set forth.
5. A pencil having its marking-lead or crayon provided with a covering-film B
of less lubricity than the crayon and inclosed in a roll composed of a sheet of
flexible material bearing weakened lines arranged diagonal to the axis of the roll,
the film B being unattached to the sheet throughout the working length thereof,
the outer edge of the sheet being secured to the roll and being provided with
perforations 3 adjacent to such edge, substantially as described and for the
purposes set forth.
6. A pencil having its marking-lead or crayon provided with a covering-film B
of less lubricity than the crayon and inclosed in a covering which may be removed
section by section from the crayon without the use of a cutting instrument, the
covering-film being unattached to the covering, substantially as described and for
the purposes set forth.
