An Improved Pointing Apparatus to be Employed in connection
with Pencil Holders.
I, FRIEDRICH WILHELM HERMANN HAAS, of Central Chambers, Halifax in the
County of York, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to provide a pencil holder with means for sharpening
the lead while in the holder and the invention consists of improved combinations of
parts hereinafter fully set forth and described.
According to this my said invention, upon the outer end of the tube which is
carried and free to slide longitudinally in an outer casing or holder, as ordinary, is
journaled a shell that projects outward from the end of the tube. The outer end of
this shell is apertured to permit the passage of the lead. And the shell is also provided
with a number of slits at its outer end, through which slits knives or cutting blades
may pass. The knives or blades are on opposite sides of the shell, and are carried by
suitable spring supports preferably situated on the outer side of the shell, or they may
be carried by other desireable means. The cutting edges of the knives or blades are
preferably sloped so that when together in the normal position they describe a cone
having its apex in line with the lead.
In order to keep the knives closed, to point or sharpen the lead, and to permit them
to open when the lead is to be pushed forward for use, I place around the knives and
shell another shell or tube connected with a flange or shoulder on the outer casing,
the second shell or tube is open at its outer end, and at that part it is provided with
slits that receive the knives and permit them to move laterally, at the same time
keeping them from turning round.
To point or sharpon the lead the same is ushed up against the knives and then
turned while in contact with the knives, which is done by turning the tube, and as
the knives are prevented turning by the shell or tube the lead will be sharpened by
coming in contact with them.
In order to pass the lead from the outer shell or casing for the purpose of using the
pencil the inner tube shell and knives are pressed forward by pushing on the finger-
piece which projects slightly beyond the outer casing, and the knives pass out of the
shell and spring outward or laterally out of contact with the lead which may now be
pushed further forward by turning the tube. To return the lead into the hoider it is
first drawn inward by turning the tube in the reverse direction and then the tube is
allowed to move inwards so as to draw the knives into the slits in the shell, any
suitable well known stop may be used, if desired, to hold the tubes in the outward
position.

COMPLETE SPECIFICATION.
An Improved Pointing Apparatus to be Employed in connection
with Pencil Holders.
I, FRIEDRICH WILHELM HERMANN HAAS, of Central Chambers, Halifax in the
County of York, do hereby declare the nature of this invention and in what
Price di

page_text: 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 to provide a pencil holder with means for sharpening
the lead while in the holder, and the invention consists of improved combination of
parts hereinafter set forth and described.
Such being the nature and object of my invention, the following is a complete
description, reference being bad to the accompanying drawings in which :-
Fig. 1 is a longitudinal sectional view of a pencil holder containing my improve-
ments.
Fig. 2 is a similar view, shewing the lead and sharpener pushed forward.
Fig. 3 is a transverse section taken through the sharpening devices.
In the accompanying drawings the letter A represents the outer case or shell of a
pencil holder, and B represents an inner tube that is guided to have longitudinal
movement in the case A. f is a spring coiled around the tube B and pressing at one
end against a partition a² within the case A, and at its opposite end against a shoulder
or sleeve on the tube B. The tubo B is permitted limited longitudinal movement
by means of a pin d2 carried by the case A and passing into a slot e² in the shoulder
or sleeve . The spring tends to hold the tube B in the position shewn in Fig. 1,
while permitting it to be pushed in the position shewn in Fig. 2.
Within the tube B
is a tube a that is adapted to turn in the same, and within the tube a is placed the
lead as usual. The lead may be removed longitudinally in the tube A by pressing
the tube a and compressing the spring f; the devices for so moving the lead being
well known, need not be further described here. The second tube a carries a finger
piece P.
The above described parts do not constitute my invention and are here described to
show one means whereby my invention, hereinafter set forth, may be carried out, it
being understood that my invention may be used with other desired forms of pencil
holders.
I will now describe my sharpening device as shewn in the drawing.
Upon the outer end of the tube a that is to say, upon the end near the writing,
and of the pencil holder is journaled a shell that projects outward from the end of
the tube a. The outer end of this shell bis apertured at o to permit the passage of
the lead b, the said shell is also provided with a number of slits 1 at its outer end,
through which slit knives or cutting blades m pass, (see Fig. 1). The knives or
blades m are on opposite sides of the shell and are carried by suitable spring
supports e that are shewn situated on the outer side of the shell h, or the knives may
be carried by other desirable means. The cutting edges of the knives or blades m
are preferably sloped, or angular so that when together in the normal position they
describe a cone having its apex in line with the lead 6 (see Fig. 1).
In order to keep the knives m closed to point or sharpen the lead b, and to permit
them to open when the lead is to be pushed forward for use, I place around the
knives mand shell another shell or tube i which is shewn connected with the
partition a. But the tube i may be otherwise suitably carried by the 'outer case A.
The shell or tube i is open at its outer end, and at that part it is provided with slits k
which receive the knives m and permit them to nove laterally, whilst keeping the
knives from turning round.
To point or sharpen the lead the same is pushed up against the knives, (see
Fig. 1.) and then turned while in contact with the knives m which is done by turning
the tube A, as the knives m are prevented turning by the shell, or tube i, the lead will
be sharpened when turned in contact with them.
In order to pass the lead b from the head shell g for the purpose of using the
pencil, the tubes Ba, shell h, and knives m are pressed forward by pushing on the
finger piece P whereby the knives m pass out of the shell i and spring outward, or
laterally out of contact with the lead 6 which may now be pushed further forward by

page_text: turning the tube a. To return the lead into the holder it is first drawn inwards by
turning the tube a in the reverse direction and then the tube B is allowed to move
inwards so as to draw the knives m into the slits k in the shell i. Any suitable well
known stop may be used, if desired, to hold the tubes B a in the outward position.
Having now particularly described the nature and object of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a pencil holder, the knives m. adapted to receive a lead 6 between them, com-
bined with means for moving the said knives out of contact with the lead, substantially
as herein described and illustrated.
2. In a pencil holder, the tube a for a lead b, and the knives m, the cutting edges
of said knives describing a cone, combined with the shell and with means as
described for actuating the tube a to move the lead & substantially as herein described,
and illustrated by annexed drawings.
3. In a pencil holder, the tube a and shell h carried by the same, combined with
the knives m, and with means such as described for actuating the tube a to move a
lead, and for moving the knives m out of contact with the lead, substantially as herein
described and as illustrated by annexed drawings.
4. In a pencil holder, the tube a shell h and knives m, combined with the shell i
having slits k for the knives m, and with means such as described for moving the
tube a to actuate a lead b, and for moving the knives m out of contact with the
lead, substantially as herein described and as illustrated by the accompanying
drawings.
