We, WILLIAM HENRY BALMAIN, of St. Helen's, in the County of Lancaster,
Manufacturing Chemist, and JOHN KEAN, of the same Place, Manufacturing
Chemist, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN THE MANUFACTURE OF FLOWERS OF SULPHUR, AND ROLL AND OTHER FORMS
OF SULPHUB," to be as follows:-
Our Invention of improvements in the manufacture of flowers of sulphur
and roll, and other forms of sulphur, consists in supplying the sulphur to the
subliming pots in a liquid or fluid state, thus avoiding many interruptions to
the process, and the unnecessary introduction of air.

..
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Thirteenth day of November, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
William Henry Balmain and John Kean, Her-special license that we, the said
William Henry Balmain and John Kean, our executors, administrators, and
assigns, or such others as we, the said William Henry Balmain and John Kean,
our 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 "IMPROVEMENTS IN THE MANUFACTURE OF FLOWERS OF
SULPHUR, AND ROLL AND OTHER FORMS OF SULPHUR," upon the condition (amongst
others) that we, the said William Henry Balmain and John Kean, by an
instrument in writing under our hands and seals, or under the hand and seal
of one of us, 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 we, the said William Henry Balmain and John
Kean, do hereby declare the nature of our, said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say) :-
Our Invention of "Improvements in the Manufacture of Flowers of Sulphur
and Roll, and other Fornis of Sulphur" consists in supplying the pots with
"brimstone" or "sulphur" in a liquid state without admitting air or interrupting
the process.
In carrying out our Invention, we introduce the material in a liquid state
by means of a pipe which connects the working pot with a separate pot in
which the brimstone or sulphur is melted, and is kept at such a level as will
ensure that the communicating pipe shall be full of sulphur. We find it

page_text: convenient to adapt to the supply pipe a tap, or cock, or other means whereby
the flow of sulphur from the melting to the working pot may be checked,
regulated, or arrested when desired, but we do not deen this essential.
Instead of using a separate pot in which to melt the brimstone, we some-
times insert a vertical tube of twelve or eighteen inches or thereabouts in
width into the working pot through a hole made in the top of a pot made
larger than the head, in order to receive it. Or the tube may be inserted at
an angle through the side of an ordinary pot, and made of such length that it
shall always dip in the melted sulphur in the pot, so as to prevent any access
of air by closing the bottom of it. The outer end of this tube being open, we
are enabled to keep up a constant supply of raw sulphur without opening
the pot.
Having now described our Invention of "Improvements in the Manufacture
of Flowers of Sulphur, and Roll and other Forms of Sulphur," and having
explained the manner of carrying the same into effect, we claim as our Inven-
tion the introduction of the raw sulphur or brimstone to the subliming pots in
the melted state, as herein set forth, whereby we are enabled to work con-
tinuously and the introduction of air during the process is prevented.
In witness whereof, we, the said William Henry Balmain and John Kean,
have hereunto set our hands and seals, the Twelfth (12th) day of May,
in the year of our Lord One thousand eight hundred and sixty-two.
W. H. BALMAIN.
