Year: 1828

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
JONES, of the Strand, in the City of Westminster, Artist, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Tenth day of December, in the
ninth year of His reign, did, for Himself, His heirs and successors, give and
grant unto me, the said Samuel Jones, His special license that I, the said
Samuel Jones, my executors, administrators, and assigns, or such others as I,
the said Samuel Jones, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times 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,
the Invention of "A NEW AND IMPROVED METHOD OF PRODUCING INSTAN-
TANEOUS LIGHT," (communicated to me by a Foreigner); in which said Letters
Patent there is contained a proviso obliging me, the said Samuel Jones, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of my said Invention, and in what manner the same is

page_text: to be performed, and to cause the same to be enrolled in His Majesty's
High Court of Chancery within two calendar months next and immediately
after the date of the said recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Jones, do hereby declare that the said Invention is fully described
and ascertained, as follows (that is to say):-
-
Into a globule or small vessel of glass, either of a spherical, cylindrical, conical,
elliptical, or angular form, of the size of from one sixteenth part of an inch
to two inches long, and from one thirty-second part to half an inch in diameter,
there should be introduced sulphuric acid, varying in quantity according to
the size of the globule or other glass vessel, which, however, is not to be
completely filled with the acid, and then the aperture or apertures in the
same is or are to be hermetically sealed or closed by melting the glass by
heating it by the blow pipe or otherwise, as may be found convenient, so that
the admission of the atmospheric air and the escape of the acid are prevented.
The bulb or other glass vessel containing the sulphuric acid is then to be
wholly or partially enclosed in or surrounded by oxymuriate or chlorate
of potash, compounded or mixed with a combustible material or materials,
such as animal or vegetable fat, camphor, inflammable gums or resins,
sulphur, and its inflammable combinations, farinacious powders, powder
from fungi, woods, bark or vegetable fibre, and vegetable sugars. These
combustible materials may be used either as a powder or as a paste made
with muilage or water, and in such proportions as circumstances may render
desirable. The proportion of oxymuriate or chlorate of potash should not be
less than one part to two parts of such of the above-mentioned combustible
materials as may be combined, compounded, or mixed with it. The globule
or bulb of glass thus prepared should then be enclosed by or attached to
paper, wood, cotton, linen, or other combustible material intended to be
ignited. And then, by the application of a blow or sufficient pressure to break
the globule or bulb of glass, the acid in the same will be brought into contact
with the composition, and instantly take fire and ignite the combustible
material by which it may be in contact.
In witness whereof, I, the said Samuel Jones. have hereunto set my
S. JONES. (L.S.)
