COMPLETE SPECIFICATION.
Improvements in Devices for Sharpening Lead or Slate Pencils.
I, FRITZ GAUL of Frankenthal in the 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:
The object of this invention is a sharpener for lead- or slate-pencils which is simple
and effective and can be used with facility by school children.
Referring to the accompanying drawing,
Fig. 1 is a vertical section, and
Fig. 2 a top view of the improved device, which consists of a downwardly tapering
round box a provided with a stationary bottom b. The width, at the top, of the box,
which is shown in the most convenient size for use, corresponds to the circle
described by the wrist when moving the band. Through the centre of the box
passes a vertical shaft or pin c secured to the bottom thereof. Said pin passes with
its top end through the cover d, placed loose on the box. The latter is internally
provided with an iron or steel lining e which has likewise a conic shape corresponding
to the tapering of the box and is fitted throughout its inner side with a file-cutting
suitable to the hardness of the articles to be sharpened with the improved device.
A guide aperture f is provided in the cover d near the circumference thereof. The
slate- or lead-pencil to be sharpened is introduced into the said aperture held fast
with the hand and turned round together with the loose cover along the metal
lining e referred to. Thereby the introduced extremity of the pencil is ground off
by the latter and shaped into a smooth and uniform pointed cone. The dust or meal
coming off the pencil is removed through a suitable number of holes provided in the
loose cover.
The improved device can also be advantageously used in a correspondingly larger
size in slate pencil manufactories.

page_text: 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 :-
:—
A sharpener for slate- and lead-pencils consisting of a round conic box a having
a sharpened or roughed inner lining e, on which the pencil is sharpened by placing
it into the guide aperture of the rotary disk or cover d and turning it round
therewith, substantially as set forth.
