Year: 1823

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME; I, CHRISTOPHER
POPE, of the City of Bristol, Spelter Maker and Metal Merchant, send
greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of His United Kingdom, bearing
date at Westminster, the Eighth day of April, in the fourth year of His reign,
give and grant unto me, the said Christopher Pope, my exors, adiñors, and
assigns, His especial licence, full power, sole privilege and authority, that he,
the said Christopher Pope, his exors, admors, and assigns, during the term of
years therein mentioned, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon Tweed, my
Invention of "A COMPOSITION OF CERTAIN METALS TO BE USED FOR THE PURPOSE
OF SHEATHING THE BOTTOMS OF SHIPS AND VESSELS, AND OF ROOFING THE TOPs
OF HOUSES, OR FOR ANY OTHER PURPOSE FOR WHICH SUCH COMPOSITION MAY BE
APPLICABLE;" in which said Letters Patent there is contained a proviso, that
I, the said Christopher Pope, shall not particularly describe and ascertain 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, and cause the same to be
inrolled in His Majesty's High Court of Chancery within two calendar months
next and immediately after the date of the said Letters Patent, that then the
said Letters Patent, and all liberties and advantages whatsoever thereby

page_text: granted, shall utterly cease, determine, and become void, as in and by the
sume, relation being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Christopher Pope, do hereby declare the nature of my said Invention to be the
covering of ships' bottoms, roofs of houses, or other the like things exposed to
the action of sea water, of the air, or of the weather generally, with thin plates
or sheathing composed of tin or zinc, or of tin, lead, and zinc united; as also
the manner of causing the said union and forming the said plates by the
following description thereof, that is to say:-
To unite tin and zinc, I take a certain quantity of zinc as it is usually made
and melt it in the usual manner in an iron pot or boiler or other utensil, and
when melted I add an equal quantity of tin, and having stirred them together
in fluid state I cast cakes of it in moulds of about 8 inches broad, 10 inches
long, and of an inch in thickness, which cakes are afterwards rolled or
hammered out into the said plates or sheathing, as hereafter more particularly
described. To unite tin, lead, and zinc, I melt a certain quantity of lead in an
iron pot or boiler, or any other uutensil, in the ordinary manner, and add to it
twice the quantity of tin. This composition I cast into. small lumps. of any
convenient size, and having melted three times as much.zine as. I had previously
melted of lead, and in an iron pot or boiler, or other utensil, as aforesaid, I add
the small lumps of tin and lead, and melt.the whole up together, which method
I find best, in order thoroughly to incorporate the lead with the zinc of this
composition. I also cast cakes of the size herein-before described, that is to
say, in 8 inches broad, 10 inches long, and of an inch in thickness, which
cakes are afterwards rolled or hammered out into the said plates or sheathing,
as hereafter described. Care should be taken in melting the various metals
that no more heat be used than will. just suffice to cause them to unite and
compound thoroughly, as when made hotter the metal is hardened. The cakes
of compound metal having been cast as aforesaid, are then to be rolled or
hammered out into plates or sheathing; when rolled or hammered out the
process is the same as that used to roll or hammer out copper, but if the cakes
are warmed to the heat of boiling water they will roll or hammer softer than
when cold.
Now, it is not essential to my said Invention that the proportions for the
compound metal herein-before named should be strictly followed; they are
such as I have found best to answer the purpose, but they may be varied by
the manufacturer to meet the market prices of the various metals; neither
are the sizes of the cakes, nor the methods of rolling or hammering out
the cakes into plates or sheathing, matters of importance; but the covering

page_text: of ships' bottoms, roofs of houses, or other the like things exposed to the
action of sea water, of the air, or of the weather generally, with thin plates or
sheathing composed of tin and zinc, or of tin, lead, and zinc united, being
to the best of my knowledge and belief entirely new, and never before used in
this Kingdom, I do hereby declare this to be my Specification of the same,
and that I do verily believe this said Specification in all respects fully and
without reserve or disguise to comply with the proviso in the said herein-before
in part recited Letters Patent contained, whereby it is my intention to maintain
an exclusive right and privilege to my said Invention.
In witness whereof, I, the said Christopher Pope, have hereunto set my
hand and seal, this Seventeeth day of May, in the year of our Lord
One thousand eight hundred and twenty-three..
