PROVISIONAL SPECIFICATION.
Improvements in and in the Manufacture of Pencil Sharpeners.
We BRUNO WESSELMANN of Hamburg in the Empire of Germany and WILHELM
LUCHT of Altona near Hamburg aforesaid, Engineers do hereby declare, the nature of
this Invention to be as follows:-
Our said Invention has reference to the instruments employed to sharpen lead and
slate pencils and relates to an improved mode of construction and manufacture and
also to the combination therewith of certain useful adjuncts, whereby we are enabled to
produce a cheaper, more efficient and more generally useful instrument than heretofore.
In making our improved pencil sharpener we take two circular or other suitably
shaped plates of thin sheet metal and form a semi-cylindrical bulge in each of an
internal diameter corresponding to the usual. diameter of pencils of the class named.
We also form in one or in both of the said plates a recess or recesses to contain a
knife or blade. The two plates are then placed together and the edge of one is
lapped over the edge of the other so as to unite them securely. The two semi-
oylindrical bulges are thus brought together so as to compose a cylindrical recess to
receive the end of the pencil to be sharpened. The knife blade inserted in the aforesaid
recess or recesses is held in its place at the proper angle by the union of the plates so
that when the pencil is inserted and the instrument turned a suitable point is cut on
the pencil.
The knife blade may be made adjustable by means of a set screw and in com-
bination with a pencil sharpener made in the foregoing manner we may apply
between the plates a spring or other knife blade to remove the ends of cigars, a
perforation being made in the plates to receive the cigar end when subjected to the
knife. The methods of fashioning and uniting the plates are of course slightly
modified when the aforesaid adjuncts to the pencil sharpener are introduced. As an
addition to the combined pencil sharpener and cigar cutter we might apply a holder
to receive a piece of rubber or a receptacle to contain matches. The bulges to
receive the pencil might be made in one of the plates only instead of in both and the
knife blade might be attached to the exterior of one of the plates by means of a set
screw by which also the angle of the knife blade might be adjusted.

Improvements in and in the Manufacture of Pencil Sharpeners.
We BRUNO WESSELMANN of Hamburg in the Empire of Germany and. WILHELM
LUCHT of Altona near Hamburg aforesaid, Engineers 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 and accompanying
drawings :-
Our said Invention has reference to the instruments employed to sharpen lead and
"slate pencils and relates to an improved mode of construction and manufacture and
also to the combination therewith of certain useful adjuncts, whereby we are enabled
to produce a cheaper, more efficient and more generally useful instrument than here-
tofore. To render our invention clearly understood we will describe the same more

particularly with reference to the annexed sheet of illustrative drawings. Figs. 1. 2. 2ª
and 3 illustrate a pencil sharpener made in accordance with our invention.
Fig. 1 is a plan.
Fig. 2 a section at the line A. B and
Fig. 3 a section at the line C. D.
In making our improved pencil sharpener we take two circular or other suitably
shaped plates a. 6 of thin sheet metal and form a semi-cylindrical bulge in each as
clearly shown in the sectional view Fig. 2. of an internal diameter corresponding to
the usual diameter of pencils of the class named. We also form in both of the said
plates a recess or recesses to contain a knife or blade m shown separately at Fig. 2".
The plates a. b are then placed together and the edge of the plate a is lapped over the
edge of the other plate as shown so as to unite them securely. The two semi-
cylindrical bulges are thus brought together so as to compose a cylindrical recess / to
receive the end of the pencil to be sharpened. The knife blade m inserted in the
aforesaid recess is held in its place at the proper angle by the union of the plates and
by a bulge or depression o so that when the pencil is inserted and the instrument
turned a suitable point is cut on the pencil.
Fig. 4 is a plan. Fig. 5 a section at E F and Fig. 6 a section at G. H of an
instrument for sharpening pencils and cutting cigar ends. In this case the knife
blade m is pivotted at o and is made adjustable against the pressure of a spring i by
means of a set screws which engages with a nut at k.
In combination with the pencil sharpener made in the foregoing manner we apply
between the plates a spring knife blade e pivotted by the spring fat t the knife being
used to remove the ends of cigars. A perforation u is made in the plates a. b to
receive the cigar end when subjected to the knife. The methods of fashioning and
uniting the plates are of course slightly modified when the aforesaid adjuncts to the
pencil sharpener are introduced, these modifications being plainly apparent from the
drawings.
Fig. 7 is a plan and Fig. 8 an edge view of an instrument which is a pencil
sharpener a cigar cutter and an ordinary knife combined. The side plates are connected
by a screws and by rivets v v. The knife blade c² is pivotted at v₁ and has a nail
nick for convenience of opening. spring catch which appears in Fig. 7 holds the
blade when closed and when open. The orifice to receive the cigar end is markod u.
The bulge h² to receive the pencil is formed in the lower plate. The screw s² holds
the cutter blade m² which is slotted for the purposes of adjustment.
Fig. 9 is a plan and Fig. 10 an edge view of an instrument which combines a
pencil cutter, a cigar cutter and a holder for a piece of rubber. The knife blade c¹ is
pivotted at t upon the top of the plate a¹. The cigar end orifice appears in dotted
lines. The rubber protruding from the holder is marked q. The cutting blade m¹ is
held by the screws and is made adjustable. The bulge h¹ is formed as shown.
Instead of a rubber as shown we might form the instrument with a receptacle for
matches.
Fig. 11 shows a slightly modified form of the instrument already described with
reference to Figs. 7 and 8, the modification appearing in the butt of the blade the
said butt having two depressions y and y¹ which receive the spring stop c¹ on
the pusher the said stop being advanced by the spring f¹ as plainly shown in the
drawings.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is.
1. The arrangement construction and combination of parts comprising our improved
instrument for sharpening pencils and the like substantially as described and as illus
trated in Figs. 1. 2. 2ª and 3.
2. The construction and combination of parts comprising the improved instrument
being a combined pencil sharpener and cigar cutter substantially as described and as
illustrated in Figs. 4. 5. and 6.

page_text: 3. The instrument forming a combined pencil sharpener, cigar cutter and knife
substantially as described with reference to Figs. 7. 8 and 11.
4. The instrument forming a combined pencil sharpener, cigar cutter and rubber
or match holder substantially as described with reference to Figs. 9 and 10 of the
drawings.
