Improvements in Paper Pencil Sheaths or Sticks.
I, CARL BOLLE, of 57, Barton Arcade, Manchester, in the County of Lancaster,
Consulting Engineer, do hereby declare the nature of this invention, which has been
communicated to me by Hugo Bremer, Manufacturer, of Neheim a.d. Ruhe,
Germany, to be as follows:-
-
In pencils the sheaths or sticks of which are formed by lapping round the black
lead or other core a sheet of paper formed with perforations at one edge, the paper
between two perforations has to be cut through by the user in order to facilitate
winding off a strip of paper to uncover the lead. The object of this invention is
to obviate this inconvenience.
The improved pencil sheath is formed of paper nicked or partly severed into
narrow strips and having perforations at one end between the strips as usual. The
sheath when lapped is coated with paint, glue, lacquer or other adhesive substance
which passes through the perforations between the outer layer and the
next one and thus causes them to adhere to each other. The bars of paper remaining
between each two perforations are then cut through, which does not allow the outer
layer to separate itself freely from the under one, as the adhesive substance between
them prevents its doing so. But by pushing a fingernail into the nick, the respec-
tive strip of paper can be easily wound off. To facilitate this the bars between
the perforations are preferably cut through with two cuts or nickings, and these
cuts are carried also through the next lower layer or through several layers, so
that the finger nail can easily be pushed into the nick. The under layers will not
loose their cohesion thereby, as the cuts are not continuous but intermittent,
extending only through the bars separating the perforations of the outer layer.

I, CARL BOLLÉ, of 57, Barton Arcade, Manchester, in the County of Lancaster,
Consulting Engineer, do hereby declare the nature of this invention which has been
communicated to me by Hugo Bremer, of Neheim a.d. Ruhe, Germany, Manu-
facturer, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
In pencils the sheaths or sticks of which are formed by lapping round the black
lead or other core a sheet of paper which along one side is perforated with round or

page_text: angular holes, the bar of paper between two perforations must be cut through by
the user in order to enable him to unwind a strip of paper for the purpose of
uncovering the lead or core. The object of this invention is to obviate this incon-
venience, which is done by forming the pencil sheaths with the bars between the
perforations ready nicked or cut through so that the winding off can be readily
started by inserting a finger nail into the nick.
In order that the invention may be readily carried into effect, I have hereunto
appended a sheet of drawings on which
Fig. 1 shows the core and sheet of paper for forming the pencil; Fig. 2 the com-
pleted pencil in side view and cross section, Fig. 3 a view of the same after the
winding on of the paper is completed but before the bars are nicked.
The pencil is formed in the known manner as represented by Fig. 1, by lapping
the lead or core with a sheet A. of paper or the like on which the lines are scratched
or indented and perforations B are formed near the end, so that the sheet is divided
into sections or strips a easily detachable from each other.
The
The sheath when lapped as shewn in Figure 3 is then coated with paint, glue,
lacquer or other adhesive substance, which naturally passes through the perfora-
tions B, which in this case are preferably made rather large and elongated, between
the outer and next lower layer and this causes them to adhere to each other.
small bars y Figs. 1 and 3, remaining between the perforations are then nicked or
cut through as shewn on Fig. 2, whereby the outer layer of paper is not detached
so as to separate itself from the one underneath and peel off, because the adhesive
substance lightly connects the outer layer with the next one underneath. If the
finger nail is now inserted into the nick next to the point, the corresponding
strip a can be readily wound off.
To facilitate the detachment of the strip, the bars are preferably nicked with a
double or broad cut as shewn on Figure 2, as the finger nail can then be inserted
more easily into the dividing nick.
With this manner of forming the paper pencil sheath there is no risk of the roll
of paper bursting open when the bars are cut through, for although the outer
layer of paper is divided by these cross cuts between the perforations, the adhesive
substance which has penetrated between it and the underlying layer assures the
cohesion of the pencil.
In order to afford a more convenient point of attack for the finger nail, it is
advantageous to make the cut b of the bars not only through the outer layer of
paper but deeper through several of the following layers, as indicated on the side
view of the pencil in Figure 2, and shown in the cross section. It need not be
apprehended that the second layer of paper would lose its cohesion, as the second and
third layers do not contain the perforations b, so that while the outer layer is divided
continuously by the alternating nicks and perforations, the lower layers are only cut
or nicked intermittently and are connected by the intermediate bars of paper left
uncut.
If the ends of the cut bars between the perforations should not adhere sufficiently
to the lower layer and in order to prevent their detachment by friction, in the
pocket for instance, it is advisable to paint a little of a lightly adhesive liquid over
the cuts. By regulating the adhesiveness of the liquid a sufficient adhesion of the
bars can be assured without preventing, the easy detachment of the bar or strip by
the finger nail.
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. The improvement in the manufacture of pencils having paper sheaths, which
consists in coating the wound pencils with paint or an adhesive substance entering
through the perforations of the paper between the outer and next layer of paper and
thereby connecting these, and cutting through the bars between the perforations
substantially as hereinbefore described and illustrated by the drawings.

page_text: 2. In manufacturing pencils with paper sheaths in the improved manner specified
in the preceding claim, the use of paper sheets having elongated perforations, sub-
stantially as herein before described and for the purpose set forth.
3. The manufacture of pencils having paper sheaths with the bars between the
perforations of the outer layer cut or nicked with double or broad cuts, substan-
tially as hereinbefore described.
4. In manufacturing pencils having paper sheets with the bars between the per-
forations of the outer layer of paper cuts separated by, carrying these cuts through
one or several layers of paper underneath the said bars substantially as hereinbefore
described and illustrated by the drawings.
