AN IMPROVED PENCIL OR LEAD HOLDER
Year: 1884

page_text: I, HERBERT JOHN HADDAN, of the firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer, do hereby declare the
nature of said Invention for "AN IMPROVED PENCIL OR LEAD HOLDER," to be as
follows:-
The improved pencil holder chiefly comprises a tubular casing of metal, wood or
other suitable material, near the upper end of which are inserted two rings, while
the lower end is provided with a longitudinal slot.
Through the lower opening of this casing is introduced a thin tube serving to
hold the lead. This tube is provided at the lower end with a collar on which rests
a helical spring enclosing the upper part of the tube and which comes in contact
with and exerts a slight pressure upon the lower one of the two rings inserted near
the upper end of the casing.
The upper end of the tube holding the lead is slightly enlarged and formed into
a cone with a projecting base. This conical extremity is split along its axis, so as
to form two equal parts which are elastic as the slit extends a considerable distance
down into the cylindrical part of the tube. In the collar at the lower end of the
tube or lead holder is cut out an elastic tongue provided with a knob or button
adapted to slide in the longitudinal slot of the casing. The tongue is bent at its
end and elastic so as to snap over the lower edge of the casing.
In the upper end of the tubular casing is inserted a pusher provided near its
upper end with a roof-shaped projection, while the lower end is made of wood or
other suitable material and forms a hollow cone which when pressed against the
conical end of the lead holder causes the two halves of the same to close together.
This pusher rests with its ring or roof-shaped projection on a helical spring held
by the upper one of the two rings inserted in the tubular casing. The conical end
of the pusher passes through the upper ring and terminates above the lower ring.
The edge of the upper end of the tubular casing is bent inward over the roof
shaped projection of the pusher so as to prevent the latter froin falling out of the
casing; while the lead holder is held in a similar manner at the lower end of the

page_text: tube, the edge of the casing being bent inward over the collar of the lead holder.
That part of the lead holder which projects downward from the collar, is split and
the lead is held in the well known manner by means of a screw cap.
When the pencil is not used the tongue in the collar of the lead holder is
disengaged by pressing on its button and the leadholder is pushed upward by
means of the same button which protrudes through the slot whereby the two
halves of the split conical end of the lead holder are pressed together and pass
through the lower of the two rings after which they are again released and snap
over the edge of the said ring.
By this arrangement the lead is completely protected, and the holder may be
conveniently carried in the pocket. For using the pencil the pusher is pressed
downward, the hollow cone closes the two halves of the lead holder whereby the
Jatter is released at the top and allowed to move downward under the influence of
the helical spring, so as to protrude beyond the lower end of the casing.

I, HERBERT JOHN HADDAN, of the firm of Herbert and Company, Patent Agents,
of 67, Strand, in the City of Westminster, Civil Engineer, for an invention for
'AN IMPROVED PENCIL OR LEAD HOLDER," 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 that class of pen and pencil holders which are provided
with means for withdrawing the point of the pen or pencil in order to prevent the
same from injury when not in use.
In the accompanying drawing which illustrates the invention, Fig 1 is an outside
view of the improved pencil holder, Fig 3 an axial section of the same with the
pencil drawn out for use, and Fig 4 an axial section in the contracted position,
while Fig 5 is a longitudinal section of a holder with pen in the contracted position,
Fig 6 a cross section of the same along line A-B of Fig 5, and Fig 2 a detail
view.
The pencil holder is constructed as follows:
The tube a (Fig 1) is provided below with a slot b, and at the upper part are fixed
or formed two internal rings c d.
Into the lower end of the tube a is introduced the tube e serving to hold the
lead (as shown by the section Fig 3). This tube e has a swelling or collar f
connected by means of the pin g (guided in the slot b), with the sleeve h which is
adapted to slide in the tube a. Against the collar fabuts a helical spring i, which
surrounds the tube e and presses with its upper end against the ring c.
The upper
end of the tube e forms a pointed cone K the base of which projects somewhat over
the circumference of the tube e. This cone is split and the slit continued far into
the tube, so as to render the latter elastic. The cone is arranged to close when
introduced into the ring c by pushing the sleeve h along the casing a; the conical
point thus passes through the ring and again opens when free, so as to rest with
its base on the ring c (Fig 4).
In the upper end of the tube a is situated the disengaging mechanism for the
split end of the tube e. It consists of a cap provided at its lower end with a
hollow cone m made of wood or other suitable material and having a shape
corresponding to the conical point of the tube e. This cap rests with its roof-shaped
collar or annular projection n on a helical spring o which abuts against the ring d.
The cap is maintained in place above its roof-shaped collar by the inward
bend a¹ of the tube a.
When the tube e, provided below the collar f with a lead holder p, is pushed
upward by means of the sleeve h (see Fig 4) the cap with its hollow cone m will
be situated close over the split end k of the tube e.
If now the cap is slightly depressed, the hollow cone m contracts or closes the
split cone k, thereby releasing the latter from the ring c. The helical spring i,
which has been stretched during the introduction of the point k into the ring c,
forces the tube e back into the position shown by Fig 3, as soon as the point k has
been disengaged.
'
Fig 2 represents the sleeve in detail. The tube h which surrounds the casing a
is held by the fingers while writing.
Fig 5 represents a pen-holder. The arrangement is substantially the same as
that of the above described pencil holder; but the tube e is somewhat shorter, the
collar is situated at the end of the tube e and adapted to receive and hold
the nib.

page_text: 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:
A pencil holder, consisting: 1, of the tube e enclosed in the casing a and provided
with an elastic extremity k, adapted to pass through the ring c, when the tube e is
pushed back by means of the sleeve h, and subsequently to expand on the said
ring. 2, of the spring-cap having a hollow cone m, adapted to close or contract
the split extremity k, thereby releasing the same from the ring c, so as to allow the
helical spring i to draw. the tube e into its original position.
