COMPLETE SPECIFICATION.
Improvements in and connected with Pencil Holders.
I, WILHELM GUSTtav Dinkelmeyer of Nuremberg!in the Kingdom of Bavaria and
German Empire, Lead-pencil 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 :-
This Invention relates to that class of pencil holders in which the lead or crayon is
contained in a holder which drops downwards out of the casing when required for
writing, and at other times is withdrawn within the casing so that the point of the
pencil may be protected in the pocket.
I will proceed to describe these Improvements with reference to the accompanying
drawings in which Fig. 1 represents a vertical section of a holder with the lead or
crayon included within the external casing, and Fig. 2 a similar section representing
the lead or crayon and its holder in the position for writing. In Fig. 1 the holder
is represented in the inverted position.
The holder a which contains the lead or crayon may be made in the usual or in any
suitable and convenient manner and is so arranged that it inay freely slide up and
down within the external casingh but so that the extent of its motion is limited by the
stud b secured to the holder a and sliding within a longitudinal slot in a tube d
which is fixed within the casing h.
The holder, when it is dropped into the writing position as indicated in Fig. 2, is
held in that position by means of a pointed bullet-shaped piece e which is free to move
within the casing. The upper end of the pencil holder a or that end of it which
is directed towards the bullet, has a slight recess formed on its face into which the
point of the bullet can fit.
If the holder be inverted, the holder a and the bullet fall into the position indicated
in Fig. 1 and if its position be reversed, or the point directed downwards, the holder
drops into the position shewn in Fig. 2 and the bullet follows with its point in the
recess in the end of the holder.
Owing to its conical or conoidal form, and the fact that it is of smaller diameter
than its surrounding casing, the bullet does not remain in a relatively vertical position
but turns on its point el so as to fall over into the position shewn in Fig. 2. This
result is further secured by the fact that the pencil holder is rarely held vertical in use.
In this position of the bullet its base or upper face e² falls with its edge under the
bottom end of a short lining tube or annular projection h¹ formed or secured within the
casing and it follows that whilst the holder is in use or approximately in the position
shewn in Fig. 2, the holder can not be pushed upwards, as any upward pressure only
tends to compress the bullet between the end of the holder and the annular rest or
abutment h¹.
In order to withdraw the pencil holder within the casing so that it may occupy the
position indicated in Fig. 1 it is only necessary to invert the holder. By this action
the bullet is brought to the central part of the casing as shown by dotted lines Fig. 2
when it is free from the annular abutment h¹ and naturally falls back to the (inverted)
top of the casing as shewn in Fig 1, when the pencil holder follows it.
In order to facilitate the motion of the bullet into the central position which must be
occupied by it before it can fall by its own weight, a second tube i may be arranged
over the tube d so as to move freely upwards or downwards when the holder is
inverted or has its position reversed. When the point of the holder is directed
upwards, this tube falls between the bullet and the casing and thus forced it into
the central position, and away from the annular abutment so as to be free
to drop.

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,―
(1) A pencil holder in which the holder is secured during use by means of a
conoidal or conical piece the point of which rests upon the end of the holder and the
base of which rests against an abutment within the casing, constructed and arranged
substantially as hereinbefore described and as illustrated by the accompanying
drawings.
(2) In a pencil holder, a conoidal or conical bullet constructed arranged and
operating substantially as hereinbefore described and as illustrated by the accompanying
drawings.
