Year: 1863

page_text: LETTERS PATENT to Arnold Budenberg, of the Firm of Schäffer and
Budenberg, of Manchester, in the County of Lancaster, for the Invention
of "AN IMPROVED BLASTING POWDER."-A communication from abroad by
Bernhard August Schäffer and Christian Friedrich Budenberg, of Buckau
Magdeburg, in the Kingdom of Prussia.
Sealed the 12th April 1864, and dated the 19th October 1863.
PROVISIONAL SPECIFICATION left by the said Arnold Budenberg at
the Office of the Commissioners of Patents, with his Petition, on the
19th October 1863.
I, ARNOLD BUDENBERG, of the Firm of Schäffer and Budenberg, of Man-
chester, in the County of Lancaster, do hereby declare the nature of the said
Invention for "AN IMPROVED BLASTING POWDER," communicated to me from
abroad by Bernhard August Schäffer and Christian Friedrich Budenberg, of
Buckau Magdeburg, in the Kingdom of Prussia, to be as follows:-
The powder consists of the combination of nitrate of potash (saltpetre),
nitrate of soda, sulphur, wood charcoal, coal, and potassio-tartrate of soda
(nitro-cali-tartaricum) which may be combined in the following proportions,
viz.,―
30 parts of nitrate of potash,
40

"
"
"
nitrate of soda,
sulphur,
wood charcoal,
common coal,
potassio-tartrate of soda,

page_text: but I do not confine myself to these proportions. By the combination of these
matters a combustible composition is obtained, particularly applicable to
blasting purposes by giving increased effect with a slow and perfect com-
bustion. These effects being principally attained by the use of the potassio-
tartrate of soda, I do not confine mayself to it, and take instead of the same,
other mineral or vegetable substances which produce the same effects.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Arnold Budenberg in the Great Seal Patent Office on the
19th April 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ARNOLD
BUDENBERG, of the Firm of Schäffer and Budenberg, of Manchester, in
the County of Lancaster, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Nineteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant
unto me, the said Arnold Budenberg, Her special licence that I, the
said Arnold Budenberg, my executors, administrators, and assigns, or
such others as I, the said Arnold Budenberg, my executors, adminis-
trators, 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 BLASTING POWDER," communicated to
me from abroad by Bernhard August Schäffer and Christian Friedrich
Budenberg, of Buckau Magdeburg, in the Kingdom of Prussià, upon the con-
dition (amongst others) that I, the said Arnold Budenberg my executors or
administrators, by an instrument in writing under my, or their, or one of
their hands and seals, 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 Arnold Budenberg, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the
following statement thereof, that is to say :-
The powder consists of the combination of nitrate of potash (saltpetre),
nitrate of soda, sulphur, wood charcoal, coal, and potassio-tartrate of soda,
3 (nitro-cali-tartaricum) which may be combined in the following proportions
viz.,―
30 to 38 parts of nitrate of potash,
nitrate of soda,
sulphur,
40
8 to 12
"
7 to 8
39
wood charcoal,
3 to 4
"
common coal,
4 to 6
"
potassio-tartrate of soda,
which are mixed together by reduction to fine particles; I do not however con-
fine myself to the proportions stated as they may be varied. By the com-
bination of these matters a combustible composition is obtained particularly
applicable to blasting purposes by giving increased effect with a slow and
perfect combustion.
Having thus described the nature of the said Invention, I would have it
understood that I do not confine myself to the use of the potassio-tartrate of
soda and common coal, as other mineral or vegetable substances which pro-
duce the same effects may be employed.
In witness whereof, I, the said Arnold Budenberg, have hereunto set
my hand and seal, this Eighteenth day of April, in the year of our
Lord One thousand eight hundred and sixty-four.
ARNOLD BUDENBERG. (L.S.)
