PROVISIONAL SPECIFICATION.
An Improvement in Pocket Lead Pencils.
I, LAWRENCE GUNN SLOAN. of 2, Long Lane, Smithfield, in the County of
Middlesex, do hereby declare the nature of this Invention (a communication to me
from abroad by Franz Hardtmuth, of Budweis, Bohemia) to be as follows :-
This Invention relates to what are known as "Coulissean" pocket pencils, that is
to say pocket pencils consisting of a tubular sheath or holder within which the pencil
is retracted when not in use and from which the pencil is caused to project for
writing purposes, the sheath or holder containing for that purpose a slide to which
the length of pencil is secured. The slide is usually an internally threaded tube into
which the end of the pencil is screwed.
The object of this invention is to enable the pencil to be more securely fixed in the
slide so as to be perfectly firm and rigid when projected for use; and for this purpose
the end of the pencil is furnished with a metal cap upon which a screw-thread is cut
or pressed, the cap being fixed on the wood by burning in or indenting the metal at
intervals. The end of the pencil on which the cap is fixed is reduced in diameter so
as to present a shoulder, which, when the threaded cap is screwed into the corre-
spondingly threaded slide, will abut firmly against the slide.

I, LAWRENCE GUNN SLOAN of 2 Long Lane Smithfield E.C. in the County of
Middlesex, a communication to me from abroad by Franz Hardtmuth of Budweis,
Bohemia, 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 :-

is reduced in diameter so as to present a shoulder, which when the threaded cap
is screwed into the correspondingly threaded slide will abut firmly against the slide.

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:
The using of a metal cap upon which a screw thread is cut or pressed, fitted on end
of cedar pencil so that the pencil is thereby firmly screwed into the slide of the
sheath or holder.
