IMPROVEMENTS IN MATCH BOXES, OR ARTICLES TO BE USED IN THE PRODUCTION OF INSTANTANEOUS LIGHT, AND IN THE MACHINERY POR MANUFACTURING THE SAME
Year: 1845

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
RUSSELL CRAMPTON, of 2, Southwark Square, Southwark, in the County of
Surrey, Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Twelfth day of July, One thousand eight hundred and
forty-five, in the ninth year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said Thomas Russell Crampton, my
exors, admors, and assigns, Her especial license, full power, sole privilege and
authority, that I, the said Thomas Russell Crampton, my exors, admors,
and assigns,. or such others as I, the said Thomas Russell Crampton, my
exors, admors, or assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, and in the Islands
of Guernsey, Jersey, Alderney, Sark, and Man, and also in all Her said
Majesty's Colonies and Plantations abroad, my Invention of "IMPROVEMENTS
IN MATCH BOXES, OR ARTICLES TO BE USED IN THE PRODUCTION OF INSTANTANEOUS
LIGHT, AND IN THE MACHINERY POR MANUFACTURING THE SAME;" in which said
Letters Patent is contained a proviso obliging me, the said Thomas Russell
Crampton, by an instrument in writing under my hand and seal, to par-
ticularly describe and ascertain the nature of my said Invention, and in
"

page_text: what manner the same is to be performed, and to cause the same to be
enrolled in Her said Majesty's High Court of Chancery within six calendar
months next and immediately after the date of the said in part recited Letters
Patent, as in and by the same, reference being had thereunto, will more fully
and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Russell Crampton, do hereby declare the nature of my said Invention
to consist in the construction of boxes for containing matches for producing
instantaneous light by means of pressure of a material not hitherto used for
such purposes. The mode of carrying out the said Invention will be fully
understood by reference to the accompanying Drawing and the following
description. The Drawing is made full size, and the same letters and figures
of reference indicate the same parts throughout.
In the accompanying Drawing, Figure 1, is represented a vertical section
of the mould A, which is of a cylindrical form. B marks a piston or plate
accurately fitting the mould or cylinder A. C marks a perforated plate fitting
the top of cylinder, as best seen on Plan, Figure 2. D marks a circular disc
or plate provided with a number of steel-tapered spikes or pins, one of which
is marked f. These spikes or pins correspond in number and diameter to the
number of perforations in the plate C, as seen in the Drawing. The operation
is as follows: The plates C and D being removed from the mould or
cylinder A, the mould A is charged about two thirds full, more or less, with
clay, to form (when pressed) one box. The plate C is attached to the mould
A in the manner shewn at Figure 3, or in any other convenient manner; and
the plate D, with its spikes, is made to descend through the plate C the
required depth into the clay by means of any well-known power, any surplus
quantity of clay being at the same time pressed through small holes formed
around the circumference of the mould in a line with the letters E, E,
Figure 1. The plate D is then withdrawn, after which the plate C is removed,
and the piston B is forced up with the clay moulded as required. The small
holes F, F, relieve the lower part of the mould A of any clay which might
pass the piston B. The clay is then baked in the ordinary manner, and such
boxes may be furnished with lids or covers of the ordinary kind. The mate-
terial which I have hitherto used is that known as potters' clay, but I wish it
to be understood that I do not confine myself to the employment of this
material, as in some cases cements in a semi-liquid state might be used and
operated upon, as before described.
Having described the nature of my Invention, I wish it to be understood
that I do not claim the forming boxes for containing matches for producing

page_text: instantaneous light in several compartments, knowing that such has been
before carried into effect; but I do claim the making of boxes for containing
matches for producing instantaneous light by means of pressure in a mould,
as before described, by any well-known mechanical power, such said boxes
being formed of clay or cements, or some such like suitable material.
In witness whereof, I, the said Thomas Russell Crampton, have hereunto
set my hand and seal, this Twefth day of January, One thousand eight
hundred and forty-six.
