I JOHANN HEINRICH WÜSTER of Ybbs on Danube, Lower Austria Engeneer do
hereby declare the nature of this invention to be as follows:-
My invention relates to a pencil and penholder with a mechanism by means of which
the writing pin or the pen can be kept within a tube or case while when used it may
be easily moved out of its case and kept in a fit position for writing while a second
pressure with the finger is sufficient to make the writing pin or pen disappear in
the case.
Referring to the drawings, Fig. 1 is a vertical axial section of my improved
pencil-and penholder, Figs. 2 and 3 are also vertical sections shewing a modification
of the holder while Figs. 4, 5, 6, 7 and 8 represent the essential mechanism of the
holder in an enlarged scale.
A Fig. 1 is a lead pencil or a pin of any other material which is kept within the
tube B. The open end of the tube B is split and is surrounded by the boss C one end
of which is provided with a screw thread while the other end is shaped conically.
The boss C may be screwed up and down and its purpose is to prevent the pin A from
sliding up and down within the tube B. When the emerging end of the pin A is too
much shortened the boss Chas to be screwed downwards after which operation A may
be readily moved up and down and drawn further out of the tube B. When a suitable
length of the pin A emerges out of the boss C, the latter is screwed upwards and
while the conically shaped end of C presses the split walls of the tube B firmly against
the surface of the pin Â the latter is secured in its position.
When the holder is used as a penholder the boss C is not required but the end of
the tube B is shaped in such a manner that a pen may be easily attached to it. The
tube B is at its upper end in rigid connection with the tube D which is of such a
diameter that it will slide easily within the tube E.
About midway of the length of the tube B or in any other suitable point is arranged
a boss F.
This boss F may freely turn round the tube B while it is prevented from sliding
up and down by the two rings G and G' which are rigidly attached to the walls of
the tube B. Rigidly attached to the boss F which is rotatory connected with the
tube B is the pin H which guides itself when moving up and down within the slots or

page_text: groove Z which are arranged in the wall of the tube J. Fig. 4 shews a view, Fig. 7
a vertical section of the tube J while Fig. 6 represents the form of the slots or grooves.
The slots or grooves in the periphery of the tube are of a zigzac form and so arranged
as to form bearing-points intermediate of the extremes of the branches of said guide-
way that is to say, some of the branches of the guideway do not extend downwards
or upwards, as the case may be, as far as other branches, and the latter may be if
convenient so arranged that branches of the same length will be formed at diametrically
opposite points in the periphery of the tube.
I will now more particularly describe the purpose of the slots in referring to Fig. 1
and 6. The pin H Fig. 1 is shewn in its highest position and this position is similar
to that of a pin in the point 1 Fig. 6. When the pin H Fig. 1 moves downwards, in
consequence of a pressure which has been exerted on the top of D, it will make a
movement equal to that from point 1 to point 2 Fig. 6 while when moving upwards
again it gets from point 2 to point 3. In case the pin H Fig. 1 is in a position
corresponding with that in point 3 Fig. 6 the pin A or the pen is free from the tube E
and may be used for writing. To the pin A required to withdraw into its case a second
pressure on the top of D is exerted and the pin H Fig. 1 will make a movement
within the slots of the tube J similar to that from point 3 Fig. 6 over point 4 to
point 5. By the formation of the slots Z the tube J is necessarily severed, the two
sections being connected again by means of another tube N Fig. 7 which is soldered
or otherwise firmly connected with each section L and M. The two sections of the
tube J Fig. 1 are connected by the tube O. To secure the tube J Fig. 1 against
sliding up and down within the tube E I arrange the disk P which is fixed in its
position by the pin S. Between P and the closed end of D a spring R is provided
which always tends to move D, when the latter has been moved downwards by hand,
automatically upwards. The pin H in Fig. 6 is moved from point 1 to point 2 by
hand while the effect of the spring R moves it from point 2 to point 3 ect.
Instead of arranging the tube J with guiding slots Z immovable and the pin H
with the boss F rotatory I sometimes make an arrangement as shewn in Fig. 2. In
this case the tube with the guiding slots may freely turn round the tube B while the
pin H is in rigid. connection with the tube B.
Another modification of any invention is represented in Fig. 3. T is a solid spindle
or tube which can be moved downwards by hand while a spring always tends to move
it upwards. The tube U may turn freely round the spindle T between the two rings
W and W which are rigidly connected with T. The tube U is surrounded by the
tube V which is provided with slots as such are shewn in Fig. 5. Z is the pin which
is rigidly connected with the tube E. The tube U makes exactly the same move-
ments as T and turns round while it slides up and down, the pin going from one slot
into the next one.
While in Figs. 4, 5, 6 and 7 slots or grooves are shewn which extend over the
periphery of the whole tube, Fig. 8 shews a different arrangement of guide slots or
grooves. In this case the pin goes during the first down-and upward movement from
point 1 over point 2 to point 3 while the second down-and following upward move-
ment will bring it from point 3 over point 4 back to point 1. It is evident that in
this case the part A Fig. 8 is severed from the tube B and has to be brought again
in connection with it by soldering connecting strips unto both parts A and B or by
surrounding them by another tube as has been shewn and described in Fig. 7.
From what has been said it is evident that it is characteristical for the guides Z
which I employ, no matter if consisting in guide grooves or slots, that they are formed
by such curves and lines which make it possible that, the guideway when moving up-
and downward or the pin when moving up-and downward, the pin slides easily and
with certainty from one guideway into the next guideway.

page_text: I, JOHANN HEINRICH WÜSTER of Ybbs on Danube in Lower Austria, Engeneer 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:-
My invention relates to pencil and penholders, viz. to tubular cases or sheaths,
wherein a pencil or pen of any description can be kept in retracted position, and from
which the said pencil or pen can be caused to protrude for use.
The invention has for its purpose so to construct the pencil holder that it might
be possible to cause the pencil or pen either to project or to withdraw by a pressure
exerted on the rear end of the pencil protruding from the tubular receptacle or on a
stud or similar part fixed to the pencil and projecting through a longitudinal slot of
the receptacle.
According to my invention, either the tubular case or the pencil, withheld therein
by a coiled spring as usual, is provided with a short cross-pin or stud, for which a
guideway is formed in the other part, the said guideway being annularly closed, viz.
returning into itself, and having both edges or borders inclined towards the axis of
the holder, so that the stud will be caused to slide along the inclined edges and to
advance in the guideway, when the pencil is moved up and down endwise in the
tubular sheath. In the borders or edges of the guideway notches or rests are
formed, wherein the stud takes and is held under the action of the spring, part
of these notches having such a depth or being at such a distance from the front
end of the receptacle that the point of the pencil will protrude from the sheath
when the stud rests in these notches, while the other notches are of smaller depth
or at such a distance from the front end of the sheath so as to keep the point of
the pencil retracted, when the stud is bearing against the closed end of one of
the same.
As with this arrangement either the tubular case or the pencil would be rotated,
while the latter is reciprocated within the former, the cross-pin or stud is fixed to
a rotatable ring or socket, or for the same end the guideway is formed in a socket
which is free to turn within the tubular case.
In the drawings left with the provisional specification and which also form an
integral part of the following detailed specification
Fig. is a longitudinal section of a pencil holder embodying the invention and
having the stud pivotally connected to the pencil and the guideway formed in the
sides of the tubular case.
Fig. 2 is a similar view of the middle portion of a pencil holder provided with
a movable socket, in the sides of which the guideway is formed, and with the stud
rigidly secured to the pencil.

page_text: Fig. 3 is a longitudinal section of the middle portion of a pencil holder having
the rotatable socket mounted to the pencil and the stud secured to the tubular case.
Fig. 4 is an elevation of a socket having a circular guideway formed in its
sides, the strips, by which the two separate parts of the socket ought to be connected
being not shewn.
Figs. 5 and 6 represent the developed surfaces of guideway sockets destined to be
connected to the tubular case and to the pencil respectively.
Fig. 7 is a sectional elevation on an enlarged scale of the guideway socket shewn
by Fig. 4.
Fig. 8 shews a portion of a guideway-socket, the closed guideway of which does
not embrace the socket, but is formed in a portion only of the circumference.
In Fig. 1, A is the pencil, which may be of any known kind or construction, and
instead of which a penholder may be provided.
The pencil A is endwise movable in the tubular receptacle E and a coiled spring R
bearing against an inner shoulder or diaphragm P of the receptacle E continously
tends to maintain the point of the pencil withdrawn in the tubular receptacle E the
extent to which the said pencil A is retracted, being limited by the stud engaged
in one or the other of the notches or rests of the guideway as hereinafter described.
Between two collars G and G¹ of the pencil A is loosely mounted a ring or socket F,
carrying a short radially extending pin or stud H which projects into the guideway
or guide groove Z formed at the inside of the receptacle or outer shell E. The
guideway Z is preferably formed of a metal socket J having a suitably shaped annular
portion of its walls cut out, and the two separate parts into which the socket is thus
severed are united by means of one or more strips or a tube O, soldered to the outer
surface. The annular recess Z may circularly surround the cylindric socket as shown
in Figs. 4, 5, 6 and 7, or it may be cut into a portion only of the socket J as illus-
trated by Fig. 8; in the first case the ring cut out from the socket J. will be a tubular
one, in the second case a plane one. Instead of cutting out a ring shaped portion of
the side of the socket J in order to form the guideway, the said portion may only be
chased to a sufficient depth as to surely guide the stud H.
in
As already stated, the guideway Z has rests or notches formed in the border into
which the stud H is pressed under normal circumstances by the coiled spring R.
With the arrangement shewn by Fig. 1, that is to say, when the guideway Z is formed
a socket rigidly secured to the inside of the tubular receptacle E, and the stud H
carried by a ring pivotally connected to the pencil A, the point of the pencil will
protrude from the said receptacle, when the stud H stands in a notch 3 Figs. 5 and 8,
the rear end of which is but few distant from the front end of the holder, and the
point will be in retracted position, when the stud H rests in another notch 1 or 5
Fig. 5 extending farther rearward or more distant from the lower end of the holder.
In order to enable the stud H to advance in the guideway from one notch to another,
the borders of the guideway Z have an inclined or oblique position with respect to the
direction in which the pencil can be reciprocated, viz. to the axis of the holder, or
these borders or margins are composed of inclined portions and portions parallel to
the said axis. Now, when the rear end of the pencil A is forced into the receptacle E
the stud H will in consequence of this arrangement be pushed out from the notch 1
Fig. 5 or 8 where it rests, and slide along the opposite inclined margin, against which
it is pressed, and when pressure is hereafter released, the said stud H will be retracted
by the spring R and slide along an inclined portion of the other margin of the guide
way to the next rest or notch.
Fig. 2 shews an arrangement wherein the stud H is rigidly connected to the
pencil, and the guide way socket J free to turn between two diaphragms of the tubular
sheath E.
In the modified arrangement shewn by Fig. 3, the guideway socket V is pivotally
mounted to the pencil A and the stud Z is fixed to the side of the receptacle E.
In this case the rests or notches of the guideway ought to be formed in the
margin of the guideway nearer the front end of the holder or the guideway socket
must be arranged in an inverse position as indicated by the respective figure.

page_text: 1, 2, 3, 4 in Figs. 5 and 8 mean four successive positions which assumes the stud H
while the pencil A is alternately pushed forward in its sheath E and allowed to be
drawn back again by the spring.
Instead of the notches 2 and 4 Fig. 8 being equally distant from the front end of
the holder they may be so arranged that notch 4 Fig. 8 is nearer the front end of the
holder than notch 2. It will be readily understood that the form of the guideway
may be varied in numerous manners; it only being essential that the said guideway
being annularly closed, that its margins upon which the spring causes the stud to
bear should be provided with at least two notches or rests, whose distances from the
front end of the holder answer to the point of the pencil protruding or being retracted
respectively, and that the said margins or borders should have inclined positions
toward the axis of the holder.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim is:
1. In a pencil holder, the combination with a tubular sheath and a pencil kept
retracted therein by a spring, of a stud fixed to either of these two parts, and of an
annularly closed guideway for said stud formed in the other parts the said guideway
having in the margins upon which the spring causes the stud to bear at least two
notches or rests differently distant from the front end of the holder, and the margins
of said guideway being inclined toward the axis of the holder, substantially as and for
the purpose set forth.
2. In a pencil and penholder the use of a guide-way which returns into itself and
which has at least two notches or rests the margins of which are so inclined toward
the axis of the holder that a pin which slides up and down end wise within said guide-.
way advances annularly from one notch to another notch, all substantially as and for.
the purpose set forth.
