page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, BARON
CHARLES WETTERSTEDT, of Rhodes Well Road, Limehouse, in the County of
Middlesex, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great.
Britain and Ireland, bearing date at Westminster, the Third day of November,
One thousand eight hundred and forty-six, in the tenth year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Baron
Charles Wetterstedt, my exors, admors, and assigns, Her especial licence, full
>power, sole privilege and authority, that I, the said Baron Charles Wetterstedt,
my exors, admors, and assigns, or such others as I, the said Baron Charles
Wetterstedt, 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, my Invention of
"IMPROVEMENTS IN THE MANUFACTURE.OF SHEET METAL POR SHEATHING AND OTHER
PURPOSES, IN PREVENTING THE CORROSION OF METAL, AND IN PRESERVING WOOD AND
OTHER MATERIALS;" in which said Letters Patent is contained a proviso, that I,
the said Baron Charles Wetterstedt, shall cause a particular description of the
nature of my said Invention, and in what manner the same is to be performed,.
by an instrument in writing under my hand and seal, to be inrolled in
Her said Majesty's High Court of Chancery within six calendar months

page_text: next and immediately after the date of the said in part 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
Baron Charles Wetterstedt, do hereby declare that the nature of my said
Invention, and the manner in which the same is to be performed, are fully
described and ascertained in and by the following statement thereof, that is
to say:-
My Invention consists, first, of a mode of manufacturing lead into sheets
.for various purposes.
Secondly, my Invention consists of a mode of manufacturing copper into
sheets, and in combining metals to be afterwards rolled into sheets for
sheathing and for other purposes.
And, thirdly, my Invention consists of manufacturing compositions or paints
for preventing corrosion of metal, and preserving wood and other materials.
And in order that my Invention may be most fully understood and readily
carried into effect I will proceed to describe the means pursued by me.
In manufacturing lead into sheets, I add to the lead when in a melted-state
a quantity of regulus of antimony, in the proportion of from one to two parts in
weight to one hundred parts of lead, and cause the same to be well stirred,
and skim off the impurities, when the mixture may be poured out and rolled
into sheets, in the same manner as lead has been heretofore manufactured into
sheets. By thus compounding the lead with antimony I am enabled to obtain
sheets superior to lead alone, and suitable for the same purposes, particularly
for water tanks or cisterns, as the lead will be less chemically acted on,. and
will consequently have less prejudicial effects on the water. I would here
state that I am aware that lead and antimony have been before combined
together, I do not therefore claim the same generally, this part of my Invention
consisting in combining antimony with lead in such proportions as will allow
of the compound being rolled into sheets.
I will now describe the second part of my Invention. In manufacturing
copper into sheets according to my Invention, I find it advantageous to
commence my operation when the copper is in the refining furnace, and just
before it would be run out, according to the ordinary process of manufacturing
copper, but I do not confine myself thereto; I add a quantity of regulus of
antimony in the proportion of one pound to about two hundred pounds of
copper, at the same time I add about two or three pounds of calcined sodą,
heated to such a degree as to be just previous to melting, and after stirring

page_text: the whole of this mass together and skimming the surface, it may be run into
moulds in the ordinary manner. and afterwards rolled.
Another part of my Invention is in the mode of combining copper and other
metals to be afterwards rolled into sheets for sheathing and for other purposes.
And in order to carry out this part of my Invention; I will suppose that I have
two furnaces side by side,. in the one of which is refined copper (such as
manufactured according to:my Invention as above described, or refined by the
ordinary mode of manufacturing copper,) ready to be run out into the moulds,
and in the other yellow metal (Muntz' patent metal) prepared according to
the ordinary manufacture, which being well known, and forming no part of
my Invention, I have not thought it necessary, to describe. I have a mould
of cast or wrought iron coated,with clay and sand, and heat the same to a red
heat, and when in that state I pour into it one part of copper to about four
or five parts of yellow. metal, but previous to the yellow metal being poured in
I'sprinkle over it with a brush a small quantity of melted tallow for the
purpose of cleaning it, I then pour in the yellow metal, when the whole mass
will be in a fit-state for rolling. I would remark, that in place of yellow metal
brass may be employed, and the.. same process may be employed with lead
and tin; the lead being first poured out and then the tin, the proportion of the
lead and tin being four or five parts of lead and one of tin, or tin and lead
combined. This sheet metal will be very suitable for water cisterns, as well as
other purposes.
Another part of my Invention consists of means of preventing the corrosion.
of metals, and preserving wood and other inaterials, by combining metals
together and then applying them as a paint on the surfaces of the metal or
wood. In preparing a paint to be applied to the surfaces of metal and wood,
I first take regulus of antimony and copper and mix them together, in the
proportion of one part of regulus of antimony to from two to three parts of
copper, and when the same is well mixed and melted together it is run out
into water, and afterwards dried by a gentle heat; I then add about two
parts of oxide of copper and grind the. whole together, 'moistening during
the operation of grinding with naptha, a sufficient quantity of naptha being
employed to bring it into a thick pasty state; I then make a' solution, composed
of tar and naptha in equal parts, and mix it with the metallic, compositions
above described in sufficient quantity as to bring the composition into a
suitable state to be employed as a paint. When preparing paints in which
zine or lead is employed, I use antimony in the proportion of one and a half
parts of antimony to one part of zinc or lead, and when tiu is used the pro-
.

page_text: portion is from two of antimony to one of tin. These materials are to be first
melted together and run into water, and ground as before described, leaving
out the oxide of copper, and when ground they may be brought into the
proper state to be employed as a paint by mixing with either a sufficient
quantity of oil and turpentine and suitable drying ingredients, or they may be 5
mixed with the naptha and tar, as before described.
Another composition to be employed for the purpose of preserving wood
and other surfaces is prepared as follows. And I would remark, that although
I prefer that a coating of this should be put on to the wood or other surfaces
to be preserved before the paint above described is put on, yet it may be 1
employed for the purpose of preserving wood and other surfaces without the
addition of paint. I take thirty pounds of tar, thirty pounds of pitch, twenty
pounds of dried soot, and four pounds of tallow of sperm oil, and melt the
whole together, adding naptha to it in the proper quantities, so as to bring it
into the suitable consistency required for the purposes to which it is to be
applied.
Another part of the Invention for the prevention of the corrosion of the
metal is by immersing sheets of copper or zinc, and also copper and zinc nails,
in a solution of muriatic acid and other materials, in the following pro-
portions:-I take about sixty pounds of muriatic acid of commerce, about ten
parts of oxide of copper or old copper, and about three pounds of regulus of
antimony, and mix the whole well, together, and place the sheets or nails
therein, and allow them to remain for two or three days, the solution being
kept at a temperature not less than seventy degrees Fahrenheit.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I do not confine myself
to the precise details so long as the peculiar character of either part of the
Invention be retained; but what I claim is,-
First, the mode of manufacturing sheet metal by combining lead and
antimony.
Secondly, I claim the mode of manufacturing sheet metal by combining
copper and antimony.
I also claim the mode of combining copper and yellow metal as herein
described, to be afterwards rolled into sheets of sheathing, and for other
purposes.
And I also claim the mode of manufacturing sheet metal by using lead and
tin as herein described.
And I also claim the treating of sheet metal and nails as herein described.

page_text: And, thirdly, I claim the modes of preparing or combining materials to be
employed as paint for the prevention of corrosion of metals, as also for the
preservation of wood and other materials.
In witness whereof, I, the said Baron Charles Wetterstedt, have hereunto
set my hand and seal, this Third day of May, in the year of our
Lord One thousand eight hundred and forty-seven.
