Year: 1860

page_text: LETTERS PATENT to George Hallett, of 52, Broad Wall, Lambeth, in the
County of Surry, Antimony Refiner, for the Invention of "IMPROVE-
MENTS IN COATING IRON AND OTHER SHIPS' BOTTOMS AND OTHER SURFACES."
PROVISIONAL SPECIFICATION left by the said George Hallett at the
Office of the Commissioners of Patents, with his Petition, on the
5th December 1860.
I, GEORGE HALLETT, of 52, Broad Wall, Lambeth, in the County of Surry,
Antimony Refiner, do bereby declare the nature of the Invention for "In-
PROVEMENTS IN COATING IRON AND OTHER SHIPS' BOTTOMS, AND OTHER SURFACES,"
to be as follows:-
This Invention has for its object improvements in coating iron and other
ships' bottoms and other surfaces. For these purposes native oxide of
antimony is employed, which is reduced into a powder, the matrix or
impurities being separated therefrom by picking and washing. The powdered
native oxide of antimony is then ground with a suitable oil or varnish or
material, to admit of its being used as a paint, and when desired other
materials may be combined with the native oxide in preparing a paint suitable
for the coating of iron and other ships' bottoms and other surfaces.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HALLETT, of 52, Broad Wall, Lambeth, in the County of Surry, Antimony
Refiner, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifth day of December, in the year of our Lord One
thousand eight hundred and sixty, in the twenty-fourth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
George Hallett, Her special licence that I, the said George Hallett, my
executors, administrators, and assigns, or such others as I, the said George
Hallett, 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 "IMPROVEMENTS IN
COATING IRON AND OTHER SHIPS' BOTTOMS AND OTHER SURFACES," upon the con-
dition (amongst others) that I, the said George Hallett, my executors or
administrators, by an instrument in writing under my, or their, or one of
their bands 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 George Hallett, do hereby declare the
nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-
This Invention has for its object improvements in coating iron and other
ships' bottoms and other surfaces. For these purposes native oxide of
antimony is employed, which is reduced into a powder, the matrix or
impurities being separated therefrom by picking and washing. The powdered
native oxide of antimony is then ground with a suitable oil or varnish or
material to admit of its being used as a paint, and when desired other
materials may be combined with the native oxide in preparing a paint suitable
for the coating of iron and other ships' bottoms and other surfaces.

page_text: Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
I take the ore called oxide of antimony, grind it to powder, and levigate it
in a mill with water to an impalpable powder, to effect which, I find the
description of mill used for levigating flints for china or porcelain manu-
factures very suitable. The ground material is then dried, either on earthen-
ware trays in a room or chamber heated by steam or hot water, or in open
pans or vessels, the sides and bottoms of which are paved or constructed of
fire-clay tiles, which are heated by a fire and flues underneath, or the drying
may be by other suitable means. When it is perfectly dry it is broken into
small fragments, and mixed with about 12 lbs. of boiled or unboiled linseed
oil (or other suitable oil or material) to the hundredweight, and ground in a
color mill similar to white lead, with or without driers, and similarly packed
in metallic or other casks for sale or use; or it may be mixed with oxide of
zinc or other ingredients before or when grinding, if found desirable.
In witness whereof I, the said George Hallett, have hereunto set my
hand and seal, this Fifth day of June, in the year of our Lord One
thousand eight hundred and sixty-one.
GEO. HALLETT. (L.S.)
