Improvements in Pencil Holders.
A communication from abroad by LUDWIG HORR, of Nürnberg, Empire of Germany,
Pencil Manufacturer.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.L.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street, Manchester, both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer 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 pencil holders in which the point of the pencil can be
respectively exposed or covered by the pushing forward or drawing back of the sheath.
In the drawings :-
Figures 1 and 2 are sections taken at right angles to each other of one form of
pencil holder constructed in accordance with this invention.
In Figure 3 there is shown an arrangement by means of which the pencil point can
be regulated by means of a screw apparatus of the usual form turning the movable
part or plunger of the case.
Figure 4 is a view of the screw arrangement for adjustably holding the lead.
Figures 5 and 6 are sectional elevations of another modification showing the pencil
holder closed and opened respectively.
Figure 7 is a cross section, and
Figure 8 an elevation of the same.
In the pencil holder shown in Figures 1 and 2, the adjustable movable plunger e has
a longitudinal slot d in which a pin c fixed to the inner portion b of the sheath a b
engages. The inner sheath b is firmly attached to the outer sheath a, so that the pin c
remains fixed. A cylinder g is fastened on the plunger e and is free to slide between
the sheaths a and b. When the pencil holder is in the position for use, as shown in
Figure 1, in order to return the same to its normal position (that is to close it) the
outer sheath a is held firm and the plunger e pushed into the same.
The cylinder g, connected with the plunger e, is thereby drawn over the point and
covers the same; in order to again expose the pencil the plunger e is simply drawn
out again (Figure 1).
In Figures 3 and 4 another arrangement of the draw out pencil holder is shown.
The plunger a in this case fits tight against a band on the cylinder k and, in
consequence of the friction, the latter, on the plunger a being pushed in, is forced out
thereby. The lead holder proper a, in which the screw arrangement for screwing
out the pencil is enclosed, is fastened by means of the pin m to an immovable socket i
attached to the outer sheath.
Should therefore the plunger a be pulled, only the cylinder k is retracted with it
whilst the lead holder is retained by means of the pin m. In consequence of this,
the pencil is exposed when the holder a is drawn out and covered when it is pushed
back. In order to be able to adjust the pencil or its lead independently of its
longitudinal projection above described by means of a screw device, that is, in order
to be able to move it by turning the plunger backwards or forwards with relation to
the sheath, the said plunger a is provided with ridges or teeth which engage
corresponding ridges or teeth of a band n attached to the ordinary screwed spindle of
the pencil. If, therefore, the plunger a be revolved, the band 'n is turned also and
actuates the screw arrangement and thereby the pencil is projected whilst the
cylinder k is prevented from revolving through the engagement of the pin m in the
slot 1.
in
In Figures 5 to 8 a pencil holder is shown in which the pencil point can be regulated

page_text: by turning the plunger u, but in which the cylinder k is carried round by said
plunger, not by means of friction, but by means of a pin t.
The construction of this pencil holder is as follows:-
The cylinder k consists in this case of two parts k', the under one of which can
be revolved round the upper. The upper half k, has, as shown in Figures 3 and 4,
a slot 1, the lower half has also another slot q, over which latter is placed the slot of
a second cylinders fitted over the cylinder k. The second cylinders is attached to
the band n of the screw apparatus which is held firm by a pin m as before. In the
slots q and ra pint engages, which is secured to the plunger in such a way that, by
turning said plunger, the two cylinders s and are turned with it and thereby the
pencil point is regulated.

If the pencil holder be in the position shown in Figures 6 and 8, and the plunger u
he pushed upwards, the pin t slides in the slot q outwards and then presses against
the upper end of this slot, whereby the cylinder is pushed forwards and the pencil is
covered as shown in Figure 5. By drawing the plunger u down again, the position
for use, shown in Figure 6, can be again attained.
The pencil holder herein described is distinguished mainly by the fact that, by the
sliding of the plunger u, the pencil can be exposed or covered, whilst by the revolving
of the same the amount of lead exposed can be lengthened or shortened, the arrange-
ment of the cylinder k in two parts facilitating this.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. An extensible pencil holder, in which the projection and covering up of the
pencil are attained by adjusting said holder, which consists of an inner sheath b
rigidly connected with an outer sheath a, the pin c of which sheath engages in a
slot d of the plunger e, substantially as described and as represented in Figures
1 and 2.
2. An extensible pencil holder, in which the exposure or covering up of the pencil
can be effected by means of a sliding motion of its plunger, and by the revolution of
the said plunger the screw adjustment of the lead may be accomplished, con-
sisting of
(a) The screw arrangement, secured by a pin m, upon which, by means of the
plunger a, the cylinder k is adjustable, and which screw arrangement can be
revolved by the teeth (or ridges) of the band n engaging in corresponding
ridges of the plunger a, substantially as described with reference to Figures 3
and 4.
(b) The cylinder k made in two parts rotatably connected with one another, and
in which the extending of the covering cylinder k as well as the revolving of
the screw arrangement is brought about by means of the pin t upon the
plunger which engages in the slots and of the inner and outer
cylinders and s, substantially as described with reference to Figures 5 to 8.

Improvements in Pencil Holders.
A communication from abroad by LUDWIG HORR, of Nürnberg, Empire of Germany,
Pencil Manufacturer.
I, WILLIAM PHILLIPS THOMPSON F.C.S. M.I.M.E. of the Agency for Foreign
Patent Solicitors 6, Lord Street, Liverpool and 6, Bank Street, Manchester, both in
the County of Lancaster and 323 High Holborn in the County of Middlesex, Civil
Engineer 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 pencil holders in which the point of the pencil can be
respectively exposed or covered by the pushing forward or drawing back of the sheath.
In the drawings :-
Figures 1 and 2 are sections taken at right angles to each other of one form of
pencil holder constructed in accordance with this invention.
In Figure 3 there is shown an arrangement by means of which the pencil point can
be regulated by means of a screw apparatus of the usual form turning the movable
part or plunger of the case.
Figure 4 is a view of the screw arrangement for adjustably holding the lead.
Figures 5 and 6 are sectional elevations of another modification showing the pencil
holder closed and opened respectively.
Figure 7 is a cross section, and
Figure 8 an elevation of the same.
In the pencil holder shown in Figures 1 and 2, the adjustable movable plunger e has
a longitudinal slot d in which a pinc fixed to the inner portion b of the sheath a b
engages. The inner sheath b is firmly attached to the outer sheath a, so that the pin c
remains fixed. A cylinder g is fastened on the plunger e and is free to slide between
the sheaths a and b. When the pencil holder is in the position for use, as shown in
Figure 1, in order to return the same to its normal position (that is to close it) the
outer sheath a is held firm and the plunger e pushed into the same.
The cylinder g, connected with the plunger e, is thereby drawn over the point and
covers the same; in order to again expose the pencil the plunger e is simply drawn
out again (Figure 1).
In Figures 3 and 4 another arrangement of the draw out pencil holder is shown.
The plunger a in this case fits tight against a band p on the cylinder k and, in
consequence of the friction, the latter, on the plunger a being pushed in, is forced out
thereby. The lead holder proper x, in which the screw arrangement for screwing
out the pencil is enclosed, is fastened by means of the pin m to an immovable socket i
attached to the outer sheath.
Should therefore the plunger a be pulled, only the cylinder k is retracted with it
whilst the lead holder x is retained by means of the pin m. In consequence of this,
the pencil is exposed when the holder a is drawn out and covered when it is pushed
back. In order to be able to adjust the pencil or its lead independently of its
longitudinal projection above described by means of a screw device, that is, in order
to be able to move it by turning the plunger backwards or forwards with relation to
the sheath, the said plunger a is provided with ridges or teeth which engage in
corresponding ridges or teeth of a band n attached to the ordinary screwed spindle of
the pencil. If, therefore, the plunger a be revolved, the band n is turned also and
actuates the screw arrangement and thereby the pencil is projected whilst the
cylinder is prevented from revolving through the engagement of the pin m in the
slot l.
In Figures 5 to 8 a pencil holder is shown in which the pencil point can be regulated

page_text: by turning the plunger u, but in which the cylinder is carried round by said
plunger, not by means of friction, but by means of a pin t.
The construction of this pencil holder is as follows:
The cylinder consists in this case of two parts 2, the under one of which can
be revolved round the upper. The upper half k, has, as shown in Figures 3 and 4,
a slot 7, the lower half has also another slot g, over which latter is placed the slot r of
a second cylinders fitted over the cylinder k. The second cylinders is attached to
the band n of the screw apparatus which is held firm by a pin m as before. In the
slots and a pint engages, which is secured to the plunger u in such a way that, by
turning said plunger, the two cylinders s and are turned with it and thereby the
pencil point is regulated.
If the pencil holder be in the position shown in Figures 6 and 8, and the plunger t
be pushed upwards, the pin t slides in the slot 7 outwards and then presses against
the upper end of this slot, whereby the cylinder k is pushed forwards and the pencil is
covered as shown in Figure 5. By drawing the plunger u down again, the position
for use, shown in Figure 6, can be again attained.
The pencil holder herein described is distinguished mainly by the fact that, by the
sliding of the plunger u, the pencil can be exposed or covered, whilst by the revolving
of the same the amount of lead exposed can be lengthened or shortened, the arrange-
ment of the cylinder k in two parts facilitating this.
Having now particularly described and ascertained the nature of the said
invention, and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim
:-
1. An extensible pencil holder, in which the projection and covering up of the
pencil are attained by adjusting said holder, which consists of an inner sheath b
rigidly connected with an outer sheath a, the pin c of which sheath engages in a
slot d of the plunger e, substantially as described and as represented in Figures
1 and 2.
2. An extensible pencil holder, in which the exposure or covering up of the pencil
can be effected by means of a sliding motion of its plunger, and by the revolution of
the said plunger the screw adjustment of the lead may be accomplished, con-
sisting of
(a) The screw arrangement, secured by a pin m, upon which, by means of the
plunger a, the cylinder k is adjustable, and which screw arrangement can be
revolved by the teeth (or ridges) of the band engaging in corresponding
ridges of the plunger a, substantially as described with reference to Figures 3
and 4.
(b) The cylinder k made in two parts rotatably connected with one another, and
in which the extending of the covering cylinder k as well as the revolving of
the screw arrangement is brought about by means of the pin t upon the
plunger which engages in the slots and 7 of the inner and outer
cylinders and s, substantially as described with reference to Figures 5 to 8.
