Improvements in Pencil-cases.
1, CARL FABER, of Schauzaecker Strasse 33 Nuremberg, in the Kingdom of
Bavaria, Empire of Germany, Manufacturer, do hereby declare the nature of this
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates to a pencil-case to be used for ordinary wooden pencils, and
consists of a metallic sleeve having an impressed spiral groove, which fits into a
corresponding groove provided in the wood of the pencil. The object of my inven-
tion is to afford a convenient means for protecting the point of the pencil, which in
distinction from other protecting devices, will not be liable to separate from the
pencil.
In order to make my meaning understood, I refer to the accompanying drawing,
in which:
Fig. 1 shows my improved pencil-case.
Fig. 2 is a cross-sectional plan of the same.
Fig. 3 is a longitudinal sectional view of a modification.
a (Figs. 1 & 2) is a cylindrical sleeve made of sheet-metal and constituting the
case for the cylindrical pencil c. The sleeve a is made open at both ends and about
one-third of the pencil's length. Upon this sleeve there is impressed a spiral
groove b, and the pencil c is provided with a corresponding spiral groove d
(Fig. 2).
The case a is pushed over either end of an ordinary cylindrical pencil, in which
the groove d has been cut. By turning the case a and thus moving it forward or
backward, the point of the pencil e may be uncovered, so that the same is ready for
use, or the case a may be brought over the point, so as to protect the latter from
injury. As the spiral grooves and d engage with each other, the case a cannot
easily slip off the pencil c.
When employing a polygonal pencil, for instance an octagonal pencil, as in the
modification illustrated by Fig. 3, the cylindrical case a is not altered, but instead
of the groove d on the pencil, I provide small notches d' on the edges of the same,
said notches being placed on a spiral line corresponding to the groove b on
case a.
I wish also to state that, in lieu of the continuous spiral groove b, I may use a
series of pegs arranged in a spiral, or even but one peg, in the case of a cylindrical
pencil.
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 combination, with a wooden pencil and a metallic sleeve constituting a
case for the same, of suitable parts formed in one with said pencil and case, and
adapted to effect a spiral motion of the latter in relation to each other, when turning
the case, for the purpose as described.
2. The combination, with a wooden pencil (c), and a metallic sleeve (a),
constituting a case for the same, of a spiral groove (6), impressed into the sleeve (a),
and corresponding parts on the pencil (c) adapted to receive the impressed parts of
sleeve (a), for the purpose as described.
3. The combination, with a wooden cylindrical pencil (c), and a metallic sleeve (a),
constituting a case for the same, of a spiral groove (b), impressed into the sleeve (a),
and a corresponding spiral groove (d) cut into the pencil (c), substantially and for
the purpose as described.

constituting a case for the same, of a spiral groove (b), impressed into the sleeve (a),
and corresponding spirally placed notches (d) cut into the pencil (c), substan-
tially and for the purpose as described.
