page_text: LETTERS PATENT to Bennett Johns Heywood, of the City of Dublin,
Gentleman, for the Invention of "AN IMPROVED HOLDER FOR LEADS,
SLATE, AND OTHER MARKING MATERIALS, APPLICABLE ALSO AS A CASE FOR
OTHER ARTICLES."
Sealed the 22nd August 1856, and dated the 25th February 1856.
PROVISIONAL SPECIFICATION left by the said Bennett Johns Heywood
at the Office of the Commissioners of Patents, with his Petition, on the
25th February 1856.
I, BENNETT JOHNS HEYWOOD, of the City of Dublin, Gentleman, do hereby
declare the nature of the said Invention for AN IMPROVED HOLDER FOR LEADS,
SLATE, AND OTHER MARKING MATERIALS, APPLICABLE ALSO AS A CASE FOR OTHER
ARTICLES, to be as follows:-
This Invention relates to a novel arrangement of that kind of holder for
containg leads and other writing materials, which permits of the lead being
pushed gradually forward as it wears away with use; the holder I construct
of wood, hard india-rubber, or other suitable material. Through the centre
of the holder stem, I form a hole to receive the lead, chalk, slate, or, other
marking material, and also a sliding rod (which is placed in the rear thereof)

page_text: for pressing the marking material forward. In the periphery of the holder I cut
a helical groove (reaching to the central hole,) to receive a pin or stud which
I attach to the sliding rod. By pushing, therefore, this stud along the helical
groove I cause the sliding rod to advance and retire, and thus propel the
marking material forward or permit of its being thrust into the holder.
The like arrangement may be employed as a holder for tooth-picks, pens,
or other articles required to be carried in the pocket.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Bennett Johns Heywood in the Great Seal Patent Office
on the 25th August 1856.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BENNETT
JOHNS HEYWOOD, of the City of Dublin, Gentleman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty fifth day of February, in, the year of our
Lord One thousand eight hundred and fifty-six, in the nineteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Bennett Johns Heywood Her special license that I, the said Bennett
Johns Heywood, my executors, administrators, and assigns, or such others
as I, the said Bennett Johns Heywood, my executors, administrators, and
assigns, should at any time agree with, and no others, from time to time and
at all times thereafter during the term therein expressed, should and lawfully
might make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an. Invention for
"AN IMPROVED HOLDER FOR LEADS, SLATE, AND OTHER MARKING MATERIALS,
APPLICABLE ALSO AS A CASE FOR OTHER ARTICLES," upon the condition (amongst
others) that I, the said Bennett Johns Heywood, by an instrument in writing
under my hand and seal, should particularly describe and ascertain the nature
of the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said Bennett Johns Heywood, do hereby
declare the nature of my said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the

page_text: following statement, reference being had to the Drawing hereunto annexed
and to the letters and figures marked thereon (that is to say):
-
This Invention relates, firstly, to a novel arrangement of that kind of holder
for containing leads and other writing materials, which permits of the lead
being pushed gradually forward as it wears away with use.
The holder I construct of wood, hard india-rubber, or other suitable
material, and down the centre of the holder stem I form a hole to receive the
lead, chalk, slate, or other marking material, and also a sliding rod or
propeller (which is placed in the rear thereof) for pressing the marking
material forward. In the periphery of the holder I cut a helical groove
(reaching to the central hole) to receive a pin or stud, which I attach to the
sliding rod or propeller for the purpose of actuating the same.
In the accompanying Drawing Fig. 1 is a side view of the improved holder;
and Fig. 2 is a longitudinal section of the same. It will be seen that a hole
is made through the centre of the holder a from end to end, and that placed
therein is a lead b and a slider c, for forcing the lead forward towards the
pointed end of the holder. This slider consists of a short metal rod, and it is
held in position by a stud d, which projects through a helical groove e, formed
in the periphery of the holder and is screwed to the slider.
For the purpose
of preventing the slider from rattling in the holder a, and of enabling it the
better to resist the pressure put upon it during the act of writing or marking
with the lead, it may have a ring of cork or other elastic packing, which will
press tightly against the inner periphery of the holder, and by friction of
contact retain the slider in position. The upper extremity of the holder
may be closed by a cap or plate, or it may be fitted with a seal like ordinary
pencil cases.
From the above explanation it will be understood that, by pushing the stud d
along the helical groove, the sliding rod will be caused to advance or retire as
required, and thereby propel the lead or other marking material forward, or
permit of its being thrust back into the holder. The like arrangement I
propose to employ as a case and holder for toothpicks, pens, and other articles
of small circumferential dimensions required to be carried in the pocket.
The propeller or slider c will then form the stein of the toothpick, pen, or
other article.
Having now set forth the nature and object of my Invention, I wish it to
be understood that I claim the construction of holders or cases for containing
marking materials, and other articles required to be carried in the pocket, as
herein described, whereby I effect the projection of the article from the case

page_text: through the medium of a traversing rod or slider actuated by a stud that
works in a helical groove or slot formed in the periphery of the case or
holiler.
In witness whereof, I, the said Bennett Johns Heywood, have hereunto
set my hand and seal, the Twenty-fifth day of August, in the year of
our Lord One thousand eight hundred and fifty-six.
BENNETT JOHNS HEYWOOD. (L.S.)'
