1, COSTI DE MEYER of Budweis, Bohemia Austria, Gentleman, do hereby declare
the nature of this invention to be as follows:-
This invention relates to a pencil holder so constructed that on turning the same
with the point downwards, the pencil will protrude to the required extent therefrom,
and will automatically fix itself in that position so that it can be used. If the holder
be turned with the point upwards, the pencil will first become freed and will then
fall back within the casing.
For this purpose the pencil is arranged to slide in a guide tube within the holder,
through a longitudinal slot of which (having a rectangular notch at the upper end)
projects a short stud fixed to the pencil. The guide tube has a sliding sleeve upon it
having a certain weight, and formed with a side opening, the front and back ends of
which are formed with inclines, into which opening projects the stud on the pencil,
the sleeve also has a projection that enters the slot of the guide tube. In consequence
of this arrangement, when the opening of the holder is turned downwards the pencil
will first protrude until its stud rests against the front end of the slot of the guide
tube, after which the weighted sleeve in sliding forward will bear with its inclined
end against the stud of the pencil and will thus force this into the notch of the slot,
and thereby secure it in position. If the pencil holder is then inverted again, the other
incline of the sleeve will push the stud of the pencil out of the notch, so that this can
fall back into the guide tube.
On the accompanying drawing Fig. 1 shews a longitudinal section of the pencil
holder with its opening turned upwards, and Fig. 2 shews the same view with
the opening turned downwards. Figs. 3 and 4. shew two forms of the sleeve shaped
weight with opening having inclines.
The nozzle a of the holder A embraces the guide tube B having the slot b with
notch b' at the front end. The pencil C can slide freely in the tube B and has a
stud c that protrudes through the slot b. D is the sleeve-shaped weight, sliding upon
the tube B, and having a projection d entering the slot b, and an opening d¹ having
inclines d, d, at each end, into which opening the stud c projects so that on the sleeve

page_text: bearing with either incline upon the stud c a component of its weight will tend to
turn the stud laterally in one direction or the other.
Thus when the holder is in the position at Fig. 2, with the pencil protruded, the
inclined will press the stud c into the notch b so as to fix the pencil in position while
on inverting the pencil, the incline d³ will push the pencil out of the notch again.
In the arrangement of the sleeve shewn at Fig. 4, the opening d¹ is formed as an
oblique narrow slot; in this case the sleeve D must be of greater weight than with
the arrangement with wide opening shewn at Fig. 3 as in the latter case the sleeve
acts with an impact upon the stud c.

page_text: I, COSTI DE MEYER of Budweis Bohemia Austria Gentleman 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 a pencil holder so constructed that on turning the same
with the point downwards, the pencil will protrude to the required extent therefrom
and will automatically fix itself in that position so that it can be used. If the holder
be turned with the point upwards the pencil will first become freed and will then fall
back within the casing.
For this purpose the pencil is arranged to slide in a guide tube within the holder through
a longitudinal slot of which (having a rectangular notch at the upper end) projects a
short stud fixed to the pencil. The guide tube has a sliding sleeve upon it having a
certain weight, and formed with a side opening the front and back ends of which are
formed with inclines into which opening projects the stud on the pencil; the sleeve
also has a tongue or projection that enters the slot of the guide tube.
In consequence of this arrangement when the opening of the holder is turned down-
wards the pencil will first protrude until its stud rests against the front end of the slot
of the guide tube after which the weighted sleeve, in sliding farther forward, will bear
with its inclined end against the stud of the pencil and will thus force this into the
notch of the slot, and thereby secure it in position.
If the pencil holder is then inverted again, the other incline of the sleeve will
push the stud of the pencil out of the notch, so that this can fall back into the
guide tube.
Referring to the drawing accompanying my Provisional Specification, Fig. 1
shews a longitudinal section of the pencil holder with its opening turned upwards,
and Fig. 2 shews the same view with the opening turned downwards. Figs. 3 and 4
shew two forms of the sleeve-shaped weight with opening having inclines.
The nozzle a of the holder A embraces the guide tube B having the slot b with
notch b' at the front end. The pencil C can slide freely in the tube B and has a
stud that protrudes through the slot b. D is the sleeve shaped weight sliding
upon the tube B, and having a projection or tongue d entering the slot b and an
opening d' having inclines d dat each end into which opening the stud c projects so
that on the sleeve bearing with either incline upon the stud ca component of its weight
will tend to turn the stud laterally in one direction or the other.
Thus when the holder is in the position at Fig. 2, with the pencil protruded, the
incline will press the stud cinto the notch 6 so as to fix the pencil in position,
while, on inverting the pencil, incline d³ will push the stud of the pencil out of the
notch again, allowing the pencil to slide back into the guide tube. The sleeve D is
of such a weight as to assist in propelling the pencil up and down the tube, if
necessary, and to partially turn it therein when pressing the stud Cinto the notch 61;
the tongue d of the sleeve, situated in the slot 6 serves to prevent the turning of the

page_text: sleeve upon the tube B, and being made of sufficient length to butt against the end of
the tube A when in the position at Fig. 1 it prevents both the sleeve and the pencil
from sliding down beyond the position shewn, so that the stud e cannot pass out of
the open end of the slot of D.
с
In the arrangement of the sleeve shewn at Fig. 4 the opening d¹ is formed as an
oblique narrow slot, in this case the sleeve D must be of greater weight than with
the arrangement with wide opening shewn at Fig. 3 as in the latter case the sleeve
acts with an impact upon the stud c.
Having now particularly described and ascertained the nature of this 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 combination of a tubular guide in which the pencil is free to
slide up and down and which has a slot through which a stud on the pencil projects
with a sliding sleeve or equivalent device so arranged as to propel the stud of the
pencil and shift it into a notch on the slot of the guide and secure it there while the
pencil projects from the holder when held point downwards, while when the pencil is
held point upwards the said device shifts the stud out of the notch so as to allow the
pencil to slide back into the tubular guide, substantially as horein described.
2. In combination with the sleeve or equivalent device referred to in the preceding
claim, a tongue that enters the slot of the guide tube and serves to prevent the sleeve
from turning and from sliding off the stud of the pencil substantially as herein
described.
