Improvements in Lead Pencils, or Holders for the same..
I, REGINALD HADDAN of the Firm of Herbert Haddan & Co. 18 Buckingham
Street, Strand W.C. London Patent Agent do hereby declare the nature of this
invention a communication to me from abroad by Henry Hunt and Henry Hunt
Junior, both of 318 North Main Street Wilkesbarre Pennsylvania in the United States
of America, Manufacturers, to be as follows:-
This pencil or pencil holder consists of a rod preferably bored axially from end to
end and resembling an ordinary lead pencil. On one end is a metal sleeve serrated to
adhere to the rod and having a screw threaded extension to receive an eraser. On the
other end is first fitted a sleeve having projecting from it in the one direction two
curved or bend extensions forming springs and in the other direction two other bent
or curved extensions forming also springs, the latter approaching each other at the
ends which are recessed so that this pair of springs may be pressed together to hold a
stick of graphite slid into the hollow rod and projecting therefrom. Over this sleeve
with its springs is slid a cap of which part is cylindrical and part conical, there being
an orifice at the apex of the cone and a shoulder where the cone joins the cylinder.
This cap encloses the sleeve aforesaid and is held in place by the first mentioned spring
extensions of the sleeve while the second mentioned extensions are compressed together
by its conical part so as to grip the graphite projecting through the orifice at the apex
of the cone. By drawing the cap partially off, the graphite may he freed for
adjustment.

I REGINALD HADDAN of the Firm of Herbert Haddan & Co. Patent Agents of
18 Buckingham Street, Strand W.C. London Civil Engineer do hereby declare the
nature of this invention a communication to me from abroad by Henry Hunt and
Henry Hunt (Junior) both of 318 N. Main Street Wilkes-Barre, Pa., United States
of America, 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 certain improvements in that class of pencils which are
provided with a tubular body adapted to receive a lead for writing purposes, the end
of the body being provided with means for clamping the lead when in position for
writing, with its end protruding from the body, and said lead being movable in the
body, so as to be adjustable, whereby, when its protruding end has been worn down,
it may be moved to present a fresh point beyond the end of the body.
The invention consists in certain novel features of the construction, combination,
and arrangement of the various parts of the improved pencil, whereby certain

page_text: important advantages are attained and the device is made simpler, cheaper, and better
adapted and more convenient for use than various other forms of pencils heretofore
employed, all as will be hereinafter set forth
The novel features of the invention will be carefully defined in the claims.
Reference is to be bad to the accompanying drawings, forming a part of this
specification, in which similar characters of reference indicate corresponding parts in
all the views.
Figure 1 is a side view of a pencil constructed in accordance with our invention.
Fig. 2 is a longitudinal axial section taken through the same.
Fig. 3 is an enlarged axial section showing the clamping-sleeve for securing the
lead in place to the body, and
Fig. 4 is a perspective view drawn to an enlarged scale and showing a spring-metal
band carrying the clamping-jaws for holding the lead and sleeve in place.
In the views, 1 indicates the body of the pencil, which is made tubular in form,
being provided with a longitudinal bollow or chamber 2, formed axially through it
and adapted to receive a lead stick 3, as clearly shown in Fig. 2. The opposite ends
of the body are open and at one end of said body is arranged a screw-threaded sleeve 4,
fitting thereon and having its end projecting beyond the body in position to receive
and hold within it an eraser 5, which may be formed of rubber in a well-known way.
The sleeve being screw-threaded throughout its whole length, it will be seen
that said sleeve is afforded a secure hold both on the body 1 of the pencil and on the
eraser 5.
The opposite end of the body 1 of the pencil is provided with a removable cap or
clamping-sleeve 6, adapted to fit over the outer side of the body, being tubular, as
clearly shown in the drawings, and said sleeve is by preference nade roughened, as
indicated in Fig. 1, in order to afford a secure hold for the fingers thereon, and at the
end of the circular portion of said clamping-sleeve is formed a projecting annular
shoulder 7 also serving to afford a secure hold for the fingers.
The end of the sleeve 6 is made conical or tapering as clearly shown at 8 in the
drawings, and at the extremity of said tapering portion of the sleeve is formed an
aperture 9.
At
The end of the body 1 on which the clamping-sleeve 6 is arranged is somewhat
reduced or cut out beneath said sleeve, as clearly shown in the sectional view, Fig. 2,
and on said reduced or cut-out portion of the body is arranged a spring-metal band 10,
of the form seen in Fig. 4, said band being constructed from a piece of metal bent to
a circular form and adapted to fit on the reduced end portion of the body.
opposite sides of its forward end the spring-metal band 10 is provided with
forwardly-projecting arms 11, having notched end portions 12, and being of sufficient
length that when the clamping-sleeve 6 is fully put on, the ends of the arms 11 will
project cutside the opening 9 and thus securely grip the opposite sides of the lead
stick 3 outside the casing 9 and so keep the lead stick from longitudinal movement,
and the said arms, 11, being constructed of spring metal and being integral with the
band 10, it will be seen that they are normally held apart and out of position to
engage the lead stick by their own elasticity. At the opposite end of the
spring-band 10 are formed projecting arms or branches 13, each of which is bent
slightly outward at its central portion, and is held in its bent position by its own
elasticity, and said arms 12 are adapted to be engaged and straitened out by the
sleeve 6, when the same is applied to the end of the body, whereby the arms act to
hold said sleeve securely against removal from the body, their free ends being pressed
into engagement with the sides of the body and serving to hold the spring down in
place thereon.
In operation, the sleeve 6 being inserted on the end of the body 1, it will be seen
that the said sleeve is held in place by reason of the elasticity of the arms 13 of said
sleeve, and when said sleeve is in position on the body its tapered portion 8 will be in
such a position as to engage the arms 11 at the forward end of the band 10 and press
the notched ends 12 thereof into close engagement with the sides of the lead stick 3,
whereby said stick will be clamped against longitudinal movement in the body at a

page_text: point outside the opening 9 of cone 8. When the sleeve 6 is moved endwise on the
body, it will be seen that its tapered portion 8 will be withdrawn from engagement
with the spring-arms 11 of the band 1) so that said arms will be disengaged
from the lead stick and said stick will be permitted to move freely in the
body 1.
From the above description of our improvements it will be seen that the pencil is of
an extremely simple and inexpensive nature and is especially well adapted for the
purposes for which it is intended, and it will also be readily understood that the device.
is susceptible of considerable modification without material departure from the
principles and spirit of the invention, and for this reason we do not wish to be.
understood as limiting ourselves to the precise form and arrangement of the parts
as herein set forth.
