IMPROVEMENTS IN PENCIL CASES
Year: 1883

page_text: LETTERS PATENT to Herbert John Haddan, of Kensington, Middlesex, for an
Invention of IMPROVEMENTS IN PENCIL CASES communicated to him from
abroad by John Hanford Knapp, of New York, United States of America
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at
the Office of the Commissioners of Patents on the 22nd May 1883.
HERBERT JOHN HADDAN, of Kensington, Middlesex, IMPROVEMENTS IN
PENCIL CASES," a communication to me from abroad by John Hanford Knapp, of
New York, United States of America,
This invention relates to improvements in extensible pencil-holders; and it
consists in the combination of a pencil-case provided with an attached lead-
propelling tube, an extension tube arranged upon and in direct contact with the
lead-propelling tube and adapted to slide longitudinally thereon independent of the
lead-propelling tube, and an exterior shell, open at one end and closed at the other,
into which shell the extension-tube and pencil-case are adapted to be inserted and
entirely withdrawn.
The invention further consists in the combination, with a shell which is open at
one and closed at the opposite end, of a pencil-case having an extension-tube
immediately upon the tube for propelling the lead, substantially as set forth.

HERBERT JOHN HADDAN, of Kensington, Middlesex. "IMPROVEMENTS IN
PENCIL CASES," a communication to me from abroad by John Hanford Knapp, of
New York, United States of America
This invention relates to improvements in extensible pencil-holders; and it
consists in the combination of a pencil-case provided with an attached lead-
propelling tube, an extension tube arranged upon and in direct contact with the
lead-propelling tube and adapted to slide longitudinally thereon independent of the
lead-propelling tube, and an exterior shell, open at one end and closed at the other,
into which shell the extension tube and pencil-case are adapted to be inserted and
entirely withdrawn.
The invention further consists of other features of combination, which will be
hereinafter described, and pointed out in the specification.
In the accompanying drawings, Figure 1 represents a side view of the pencil-case
when the same is inserted into the protecting shell.
Figure 2 is a similar view, the protecting-shell being shown in section.
Figure 3 is a side view of the pencil-case when the extension-tube is drawn out.
Figure 4 is a similar view of the same, the extension tube being shown in
section.
•
Figure 5 is a sectional side view, when the extension tube is drawn out and
inserted into the open end of the shell.
Similar letters indicate corresponding parts,
In the drawings the letter A designates a tubular shell, which is open at one
end, while its other end is closed by a cap, B, secured therein-Into the open end
of the shell fits the extension-tube C, which is closed at one and open at its
opposite end, and which is placed immediately upon the tube a of the pencil.
case, D, said tube a serving to propel the lead through the tube b by mechanisın
generally used for this purpose.
Near the rear end of the tube a is formed a shoulder, c, which co-operates with
a shoulder, d, formed near the open end of the extension tube (see Fig 4) so that a
stop is formed which prevents the extension-tube from being drawn out beyond
the desired point. The extension-tube C is made of such a diameter, that it fits
the open end of the shell A, and it is equal in diameter to the cap B, so that, when
the pencil-case is placed into the shell, (Figs 1 and 2) both ends of the shell have a
uniform appearance. In the example shown in the drawings the cap B is made
smaller in diameter than the body of the shell; but, if desired, the shell may be made
of uniform diameter throughout, and in this case the outer end of the extension-
tube will be enlarged, so that the diameter of this enlarged portion will be equal
to that of the shell, while the main portion of the extension-tube fits the interior
of the shell. In the interior of the cap B is secured a stop, e, and if the pencil-
case is inserted into the shell A, the shoulder f of the pencil-case strikes this stop
and prevents the point of the lead from being broken by coming in contact with
the cap B. When the pencil-case is inserted into the shell, as shown in Fig 2, the
point of the lead is fully protected. When the pencil case is withdrawn from the
shell A, and the extension tube is drawn out, the pencil can be used conveniently
for writing, and if it is desired to obtain an additional length for the handle the
extension-tube is inserted into the shell, as shown in Fig. 5-If the extension-tube
is pushed in, and the pencil-case is inserted into the shell, the whole device can be

page_text: conveniently carried in the vest-pocket; or the shell may be so constructed that it
can be attached to the garment, and when the pencil-case is withdrawn and the
extension tube is drawn out, as shown in Figs. 3 and 4, the pencil can be used with
convenience.
I am aware that pencil-cases have been made which fit a shell. In some cases
the pencil-case is made with a pencil-tip-propelling device and with a lead-
propelling device, and when the pencil tip is drawn inward, the pencil-case can be
inserted into the shell. This device is much more expensive than that described
above. In other cases the pencil-case is simply made with a lead-propelling device,
and the shell is made telescopic. In this case, if the pencil-case is withdrawn from
the shell, the pencil cannot be used conveniently, while this pencil-case allows of
using the pencil either with or without the shell.
What I claim as new, and desire to secure by Letters Patent, is:
1. The combination of the pencil-case D, provided at one end with an attached
lead-propelling tube, a, an extension-tube, C, arranged upon and in contact with
the lead-propelling tube and adapted to slide longitudinally therean independent of
any movement of the lead-propelling tube, and an exterior shell open at one end
and closed at the other, into which shell the extension-tube and the pencil-case are
adapted to be inserted and entirely withdrawn substantially as described.
2. The combination, with a shell which is open at one and closed at the
opposite end, of a pencil-case having an extension-tube immediately upon the tube
for propelling the lead, substantially as set forth.
In witness whereof I the said Herbert John Haddan have hereunto set my
hand and seal this 21st day of November A.D. 1883.
