Improvements in Pencil Holders.
I, WILLIAM LLOYD WISE, of 46, Lincoln's Inn Fields, in the County of Middlesex,
Consulting Engineer and Patent Agent, do hereby declare the nature of this invention
to be as follows :-
The pencil holder forming the subject of the present invention, has for object the
utilization of short lengths of pencil such as would otherwise ordinarily be wasted.
The pencil holder is constructed to form a continuation of the pencil.
It is advantageous to have a pencil holder such as besides being durable shall also
be simple and can be used with rapidity-and these advantages are believed to be
attained in the improved pencil holder, of which several modifications are hereinafter
described, by the employment of suitably arranged conical sheaths or tubes.
In the accompanying sheet of illustrative drawings,
Fig. 1 shews in elevation one form of pencil-holder which is provided with a
piece of india-rubber (for erasing purposes) in its rear end; a pencil is shewn
inserted and held in position for use, and the outer sheath or tube is shewn partially
broken away.
Fig. 2 shews the rear portion of the pencil-holder with the inner sheath or tube
drawn back so that the india-rubber is covered over, and the pencil is loose in the
sheath or tube.
Fig. 3 is a longitudinal section through the pencil-holder with the inner sheath or
tube drawn back as in Fig. 2.
Fig. 4 is a section on the line E F ; and
Fig. 5 a section on the line G H of Fig. 3.
Fig. 6 is an elevation of the rear portion of the outer conical sheath or tube, the
front portion being broken away.
Fig. 7 is a rear elevation of the same.
Fig. 8 is a section on the line I-K of Fig. 6.
Fig. 9 is an elevation of the rear portion of the inner sheath or tube, the front
portion being similarly shewn broken away.
Fig. 10 is a section on the line L-M; and
Fig. 11 a section on the line N-O of Fig. 9.
Fig. 12 shews partly in elevation and partly in section, a modification of the pencil
holder, in which the inner clamping sheath or tube is replaced by nipping or
clamping tongues, the pencil-holder being shewn provided with a pencil ready
for use.
Fig. 13 is a section on the line C-D of Fig. 12.
Fig. 14 shews in section the rear portion of the pencil-holder, the pencil being
assumed to be lying loose in the inner sheath or tube which is shewn drawn back.
Fig. 15 represents partly in elevation and partly in section a modification of the
pencil-holder in its simplest form and comprising an elastic conical sheath or tube,
with the pencil therein shewn clamped ready for use.
Fig. 16 is a section on the line B, Fig. 15.
Fig. 17 illustrates the pencil holder without pencil, the rear end being shewn
broken off.
The pencil holder (Figs. 1 to 11) consists essentially of an outer conical sheath or
tube which serves to effect the clamping of the short pieces of pencil which have
been pushed into and are situate within the same. Between this outer sheath or

page_text: tube and the pencil, is an inner sheath or tube that is slotted at its forward end so
as to form tongues that are pressed together by the backward movement of the conical
(but not slotted) front portion of the outer sheath or tube relatively to the inner one ;
this operation serves to secure the pencil in position by clamping.
The double sheath or tube arrangement enables the rear end of the pencil holder
to receive a piece of india-rubber (for erasing purposes); this is effected by means of
a kind of slot arrangement which allows metal tongues to move over and relatively
to one another in such a manner that the piece of india-rubber is firmly held, and
is protected from injury when the pencil is not in use, as for example, when it is
carried in the pocket.
I will now proceed to describe the invention more fully by reference to the
drawings.
The outer sheath 2 (Fig. 6) is formed at its rear or wide end with a number of
slots (in the present example six slots are shown) in such a manner that the sheath
or tube is thereby divided at its periphery into a number (six in the present case)
of approximately equal portions or tongues t¹, t², t³, t^, to and to. Some of these
tongues, in the present case t³, t, and to, are bent inwardly in such a manner that
an annular space is formed that extends between the outer tongues t¹, 18, ts and
the inner ones t2, 4, to, for the reception of the inner sheath or tube (Fig. 5) as
will be hereinafter more fully explained.
The inner sheath or tube h³ (Fig. 9) has, corresponding to the above slots, six similar
slots of approximately the same length as those in the sheath or tube h³, but with the
difference that the former slots only begin at a certain distance from the upper or rear
wide end of the inner sheath or tube.
These slots divide the sheath or tube h³ at its periphery into six parts f³, f³‚ƒ³‚ƒˆ‚ƒ°‚
and f. Portions of the parts f2, f, and f (corresponding to the tongues t, t, and to)
are removed towards the rear end the remaining portions forming tongues that are
slightly bent inwardly, as shown in Figs. 9 & 10.
The front, thin end of the sheath or tube h³ is also provided with a number of slots
(Fig. 4), whereby elastic tongues are formed which can be clamped (tightened) by
the front end of the sheath or tube h². The rear end of the sheath or tube h³ is
provided with a rim a.
6
The sheath or tube ³ is introduced into the sheath or tube h* in such a manner that
the downwardly bent parts t³, t & t of the sheath or tube ³ enter in the corresponding
openings behind the tongues f³, f*, & ƒ (see Figs. 3 & 5). The movement of the two
sheaths or tubes within each other is limited by a pin n which is formed on or carried
by the sheath or tube h² and moves in a slot in the sheath or tube h³ (shewn in Fig. 3
without shading for the sake of clearness).
To secure the piece of pencil 62 in the holder just described, its two sheaths or tubes
are brought into their pulled-out positions shewn in Fig. 2 or 3. The pin n then
hears against the front end of the slot in h³. The pencil can now be introduced in
front into the concentric sheaths or tubes h² and h³ (Fig. 3).
The pencil is brought into a position ready for use by moving the sheath or tube h³
forward within the sheath or tube h² and into the position shewn in Fig. 1. The
pencil will then be firmly connected with the holder by elastic clamping.
The arrangement for holding the pencil is situated in front, as described; whilst at
the rear end there is provided a device for holding a piece of india-rubber (for erasing
purposes) this device consisting mainly of the tongues t2, t & to of the sheath or tube h².
These tongues clamp the india-rubber in all positions of the sheaths or tubes relatively
to each other. The length of the india-rubber is made such that when the sheaths or
tubes are pushed together, that is to say when the holder is in a position for use, the
india-rubber is exposed and is also ready for use as shewn in Fig. 1.
By drawing back provisionally the inner sheath or tube a certain distance by
means of the rim, the pencil will be released and can be moved rearwardly between
the tongues f, ƒª & ƒ³.
On drawing the inner sheath or tube back further, the rear end of the pencil is
secured in its rearward position, owing to the curved or bent portions of the

page_text: tongues t³, t&t then exerting a certain pressure upon the tongues f³, f* & f* and
consequently upon the pencil. The india-rubber is at the same time secured by the
free or end portions of the tongues t*, * & to and is covered over by the widest or rear
part of the inner sheath or tube /³.
When the device for holding the india-rubber is not required the construction of
the rear end of the holder based upon the pushing in of the tongues t², 4 & to and the
tongues f³, f* &f, may be dispensed with; and the inner elastic sheath or tube h³
may be replaced by a tongue-piece or clamp-piece ps s¹. This modification is
illustrated in Figs. 12 to 14. Between the outer sheath or tube h¹ of this modification
and the pencil 6 are situated the clamping tongues s & s', which are fixed to the cap
or cover p, and are preferably (for the purpose of centreing) provided with partially
stamped-out elastic pieces z & z. The pushing forward or the drawing back of the
clamping piece pss effects the clamping or releasing respectively of the pencil. The
pencil can, whilst in its released position, be moved as required. Instead of introducing
the pencil from the front end, it may be introduced from the rear, if an aperture is
provided for that purpose in the cap or cover p.
The pencil-holder may be prevented from rolling about when laid down by making
the rim of the cap or cover p four-sided.
A modification that is still more simple in construction than that shewn in
Figs. 12 to 14 (employment of substitute for inner sheath), consists in the very
simplest modification of the inner conical sheath or tube h³, the outer conical sheath
being dispensed with.
The conical sheath or tube h³ with its tongues etc. is reduced to a simple conical sheath
or tube with slotted front portion, as shewn in Figs. 15 to 17. The slot or slots a must
be such that the pencil can be moved within the slotted portion of the sheath or tube
by hand without much exertion, whilst this portion of the sheath or tube must afford
sufficient pressure to hold the pencil whilst writing. The pencil can be moved forward
within the sheath or tube by means of any suitable thin pin or rod applied to its
rear end..

Improvements in Pencil Holders.
A communication from E. WEHRLI, of Aarau, and E. BALLY, of Schönenwerd.
I; WILLIAM LLOYD WISE, of No. 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Patent Agent, 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 :-
The object of this invention is to provide a pencil holder in which even extremely
short lengths of pencil may be conveniently utilized, the holders serving as a pro-
longation of the said lengths of pencil.
It is advantageous to have a pencil holder such as, besides being durable, shall
also be simple and can be used with rapidity, and these advantages are believed to
be attained in the improved pencil holder, of which several modifications are
hereinafter described, by the employment of suitably arranged conical sheaths or
.tubes.
In the annexed drawings,

use.
Fig. 2 illustrates the same pencil holder in section, the pencil being assumed to
be lying loose in the holder, and the rubber piece being shewn covered as indicated
in dotted lines.
Fig. 3 is an elevation partly in section of the outer sheath or tube.

page_text: Fig. 4 is an elevation partly in section of the inner sheath or tube.
Fig. 5 is a rear elevation of Fig. 3.
Fig. 6 is a section on the line A-B of Fig. 4.
Figs. 7 and 8 are front elevations of Figs. 3 and 4 respectively.
Fig. 9 is an elevation partly in section of a modified arrangement of pencil
holder, in which the inner clamping sheath or tube is replaced by nipping or
clamping tongues, and the outer sheath or tube is rendered elastic at its front end
by means of slots; the pencil is shewn in position ready for use.
Fig. 10 is a view similar to Fig. 9, but modified by having an overlapping
tangentially elastic outer sheath or tube.
Fig. 11 is a sectional elevation of the pencil holder illustrated in Fig. 9, but
with the pencil assumed to be lying loose in the holder which is shewn turned
through an angle of 45°.
Fig. 12 is a section on the line C-D of Fig. 9 looking upward.
Fig. 13 is a similar section on the line C-D¹ of Fig. 10.
Fig. 14 is a section on the line E-F of Fig. 9.
Fig. 15 is a section on the line E¹-F' of Fig. 10.
Fig. 16 is a section on the line G-H of Fig. 11 looking upward.
Fig. 17 represents partly in elevation and partly in section, a modified pencil
holder this arrangement being of very simple character and comprising an elastic
conical sheath or tube with the pencil shewn clamped ready for use.
Fig. 18 is a similar view to Fig. 17, but with overlapping tangentially elastic
conical sheath or tube.
Figs. 19 and 20 illustrate the pencil holder as in Figs. 17 and 18, but without
the pencil; the rear end of the sheath or tube being shewn broken off in each
case.
Fig. 21 is a section on the line J-K of Fig. 17.
Fig. 22 is a section on the line J'-K' of Fig. 18.
The pencil holder (Figs. 1 to 8) comprises a conical sheath or tube which secures
by clamping the piece of pencil that is situated in the same and which is pushed
forward into the position in which it is to be secured. Between this outer sheath
or tube and the pencil is an inner sheath or tube that is slotted at its forward end
so as to form tongues that during their forward movement are pressed together by
the forward part of the outer sheath or tube, the said forward part of which is
conical but is not split nor slotted; this operation secures the pencil in position by
clamping. The inner sheath or tube may also be made slightly conical.
The double sheath or tube arrangement enables the rear end of the pencil holder
to receive a piece of rubber (for erasing purposes); a slot arrangement being
provided such as to allow of the tongues to be pushed and moved relatively to one
another in such a manner that the rubber is firmly held, and is protected from
becoming dirty when the pencil is not in use, for instance when carried in the
pocket.
The outer sheath or tube h² (Fig. 3) is formed at its rear or wide end with a
number of slots (in the present example there are six) in such a manner that the
sheath or tube is thereby divided at its periphery into a number (six in the present
case) of approximately equal portions or tongues t¹, t², t³, t, to, te. Some of these
tongues in the present case the tongues t², t, te, are bent inwardly in such a manner
that an annular space is formed between the outer tongues t¹, t³, to, and the inner
ones t2, t, t, for the reception of the inner sheath or tube.(Fig. 5) as will be more
fully explained hereinafter.
The inner sheath or tube 3 (Fig. 4) has, corresponding to the above named
slots, six slots at its rear end; they are of approximately the same length as those
in the sheath 2, but with the difference that the first named slots start at a certain
distance from the rear or wide end of the inner sheath or tube. These slots divide
the sheath or tube 3 for this distance at its periphery into six parts f, f, ƒ³‚ ƒ ^,
fo, f. Portions of the parts f², f,f, (corresponding to the tongues t², t, t,) are
removed towards the rear end, the remaining portions forming tongues, that are

page_text: slightly bent inwardly as shewn in Figs. 4 and 6. The forward thin end of the
sheath is also formed with a number of wedge shaped slots or excisions a
(Fig. 8) whereby elastic tongues are formed, which can be clamped by the front
end of the sheath or tube 2. The rear end of the sheath or tube h³ is provided with
a rim for convenience in handling. The sheath or tube ³ is introduced into the
sheath or tube 2 in such a manner that the downwardly bent parts t³, t, t, of the
sheath or tube 2 enter the corresponding openings behind the tongues ƒ³, ƒª, ƒª
(Figs. 1 and 2). The relative movement of the two sheaths or tubes within each
other is limited by a pin n formed on or carried by the sheath or tube h³, and
moving in a slot in the sheath or tube h³.
To secure the piece or length of pencil 6 in the holder just described the two
sheaths or tubes are brought into their pulled out positions shown in Fig. 2. The
pin n then bears against the forward end of the slot in ³. The pencil can now be
introduced in front into the concentric sheaths or tubes 2 and 3 (Fig. 2). By now
moving the sheath or tube h³ in the sheath or tube so that the parts take up the
position shewn in Fig. 1, the pencil is brought into position ready for use, and is
then firmly connected with the holder by elastic clamping. Whilst, as above
mentioned, there is at the forward end a securing or clamping device for the pencil,
there is at the rear a securing device for holding a piece of rubber for erasing
purposes, this device consisting mainly of the tongues t² 4, to of the sheath or
tube h. These tongues clamp the rubber in all positions of the sheaths or tubes
relatively to each other. The length of the rubber is made such that when the
sheaths or tubes are pushed together, that is to say, when the pencil is in a position
for use, the rubber will also be free for use (Fig. 1).
By first drawing back the inner sheath or tube h³ for some distance by means of
the rim x, the pencil b can be caused to fall back between the tongues fff; by
still further drawing back the inner sheath or tube the pencil is held at its rear end
in its rear position, owing to the initial conicity of the tongues t², t¹ and to exerting
a certain amount of pressure upon the tongues f, f, f, and consequently upon the
pencil.
The rubber is at the same time held by the free or end portions of the tongues t
t', to, and is covered by the wide or rear part of the inner sheath or tube h³ (as
indicated by dotted lines in Fig. 2).
When the device for holding the rubber is not required the above described con-
struction of the rear end of the holder may be dispensed with; and the inner elastic
sheath or tube ³ may be replaced by a tongue-piece or clamping piece ps s¹. This
arrangement is illustrated in two modifications in Figs. 9 to 16.
z
Between the outer sheath or tube h¹, (or h¹*) and the pencil b, are situated the
clamping tongues s and s¹ which are fastened to the cap or cover p, and are preferably
(for the purpose of centreing) provided with partially stamped-out elastic pieces
and z. The pushing forward or the drawing back of the clamping piece pss effects
the clamping or the releasing respectively of the pencil. The pencil can in this case
also be moved as desired whilst in its released position.
Instead of introducing the pencil from the front end, it may be introduced from
the rear, if an aperture is provided for that purpose in the cap or cover p. The
sheath (Fig. 9) is in this case rendered elastic by means of wedge shaped slots or
excisions a in the forward end, and the sheath h¹* (Fig. 10) is rendered tangentially
elastic by overlapping (as will be hereinafter described).
The pencil holder may be prevented from rolling when laid down, by making the
rim of the cap or cover p square or polygonal.
A modification that is still more simple than that shewn in Figs. 9 to 16 consists
in the arrangement of a single sheath or tube which has a conical and elastic front part,
so as to combine the actions of the outer sheath or tube h³ and of the split inner
sheath or tube h³.
The sheath or tube h³ with its tongues &c., is in this case in the form of a simple
conical sheath or tube h (or h*), as shewn in Figs. 17 to 22. The sheath may be
rendered elastic by means of a slit or slot a in its front portion (as h in Figs. 17,

page_text: י
.
19 and 21), or by simply overlapping one longitudinal edge of the sheath over the
other throughout its length, so that this overlapping forms the beginning of a spiral
(as in Figs. 18, 20 and 22).
The pencil can be moved forward within the sheath or tube by means of any
suitable thin in or rod applied to its rear end; such an extra body or instrument not.
being required in the arrangements illustrated in Figs. 9 to 16, by reason of the
clamping device.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1.. A pencil holder with a device for holding a piece of rubber for erasing purposes,
the said pencil holder consisting of two sheets 2 and 3 arranged one within the other,
the relativo movement of which effects the clamping or the release of the pencil, and
provided at its rear part with tongues, the arrangement being such that the tongues:
of the outer sheath h² enter alternately into openings behind corresponding tongues of
the inner sheath h³, into this inner sheath /, and there continuously hold the piece
of rubber, whether in a position ready for use, or covered.
2. In a pencil holder of the kind referred to in the previous claim the tongues t², tª, t
of the sheath 2, for holding the rubber which tongues enter into openings of the
sheath over the tongues 2, 4, 6, and hold the rubber within the sheath ³, and
share the movement of the outer sheath in the inner sheath with the rubber.
3. In a pencil holder, a conical sheath with a clamping piece capable of forward
and rearward movement between the sheath and the pencil, for clamping or releasing
the latter.
4. In a pencil bolder, a single conical sheath with elastic forward end, which fits
on the pencil and holds the same in position for use.
