PROVISIONAL SPECIFICATION left by the said Philip William Flower,
Henry Nash, and Richard Heathfield at the Office of the Com-
missioners of Patents, with their Petition, on the 12th May 1869.
We, PHILIP WILLIAM FLOWER, of Melyn Tin Plate Works, Neath, in
the County of Glamorgan, Manufacturer, and HENRY NASH, of No. 5,
India Buildings, Water Street, Liverpool, in the County of Lancaster,
Merchant, and RICHARD HEATHFIELD, of Birmingham, in the County of

page_text: Warwick, Manufacturer, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN COATING SHEETS OF METAL WITH OTHER
METALS," to be as follows:-
Our Invention consists of improvements on or additions to an Inven-
tion of "Improvements in Coating Sheets of Metal with other Metals
and other Substances," for which Letters Patent were granted to Andrew
Whytock, of 12, Little Saint Andrew Street, Upper Saint Martin's Lane,
in the County of Middlesex, dated October 11th, 1859, No. 2313. The
said Patent is now the property of Messrs. Morewood and Company, of
Birmingham Heath, Birmingham, in the County of Warwick, of which
firm one of the present applicants, namely, Richard Heathfield, is a
partner.
The Provisional Specification of the said Patent describes the nature
of the Invention in the following words:-

"This Invention has for its object improvements in coating sheets of
metal with other metals and other substances.
"Heretofore sheets of metal have been coated by dipping them
separately into the molten metal or other fluid substances used for
coating, and it is well known that for various purposes lengths of
"coated sheet metal are required greater than the length of a single s
sheet, and that in such cases it has been usual to connect several sheets
together by grooving, linking, rivetting, or otherwise after they have
been separately coated with the metal or other coating substance. Now
my improvements consist in combining sheets of iron or of other metal
together at their edges by any of the ordinary means above mentioned
before they have been coated, or such connecting of the sheets together
may be only temporary where it is desired simply to obtain the advan-
tages of a more continuous process of dipping a series of plates or
"sheets into a coating fluid. The joined or connected series of plates or
"sheets are then immersed in succession into the bath of melted metal or a
"other substance with which they are to be coated, by which means not
"only will the general surfaces be coated but the permanent joints will
"also be coated, and the joints or seams thereby more advantageously
"made, and at the same time the connecting of several sheets or plates
together before coating them will facilitate their being moved into and 3
"from the melted coating metal or substance, and will also facilitate
"the movement of a succession of plates or sheets into and through a

"hot chamber in order that they may become heated, and be caused in
passing out of the hot chamlier to enter the flux (floating on the bath
5. of coating metal) in a more highly heated state, whereby the coating of
"tle sheets or plates in some cases will be more effectually accomplished.
By thus joining or connecting together numerous sheets or plates of
iron or other metal the manufacturer will be enabled to supply his
"customer with great lengths of coated sheet metal, from which may be
"cut any desired lengths, and the manufacturer will by connecting the
"sheets or plates either permanently or temporarily be advantaged by
rendering the process of coating more continuous as compared with
"the coating the sheets or plates separately."
"
Our Invention consists in coating the sheets to be joined with a
preliminary coating of metal before they are connected together and
passed through the bath of melted metal by which the final and
continuous coating is to be given to them. By this preliminary coating
the junction of the sheets or plates is in some cases more efficiently made
than in the case of sheets or plates without a preliminary coating; for
example, when the ends of the plates are connected together in such a
way as to prevent the melted metal of the final coating from entering
between them the preliminary coating is melted and effects the junction
or soldering together of the plates. The preliminary coating is especially.
applicable to the manufacture of connected sheets.of iron coated with tin
or terne metal, but we do not limit ourselves to any particular coating
metal or alloy.
In applying the preliminary coating the sheets may either be coated
with the said preliminary coating over their whole surface, or only such.
portions of the edges of the sheets may be coated as are bent or otherwise
made use of for effecting the junction of the sheets. In general we
prefer to effect the preliminary coating by the use of a melted metal or
alloy of the same kind as that with which the final coating of the con-
tinuous sheet is to be effected, but we do not limit ourselves thereto, as a.
different metal or alloy may be employed.

Lord One thousand eight hundred and sixty-nine, in the thirty-second
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto us, the said Philip William Flower, Henry Nash, and Richard
Heathfield, Her special licence that we, the said Philip William Flower,
Henry Nash, and Richard Heathfield, our executors, administrators, and
assigns, or such others as we, the said Philip William Flower, Henry
Nash, and Richard Heathfield, 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 COATING SHEETS OF METAL WITH OTHER
METALS," upon the condition (amongst others) that we, the said Philip
William Flower, Henry Nash, and Richard Heathfield, our exccutors
or administrators, by an instrument in writing under our or their
hands and seals, or under the hand and seal of one of us or them,
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 Richard Heathfield, on behalf of
myself and the said Philip William Flower and Henry Nash, do hereby
declare the nature of the said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and by
the following statement thereof, that is to say:
Our Invention consists of improvements on or additions to an Inven-
tion of "Improvements in Coating Sheets of Metal with other Metals
and other Substances," for which Letters Patent were granted to Andrew
Whytock, of 12, Little Saint Andrew Street, Upper Saint Martin's Lane,
in the County of Middlesex, dated October 11th, 1859, No. 2313. The said
Patent is now the property of Messrs. Morewood and Company, of Bir-
mingham Heath, Birmingham, in the County of Warwick, of which firm
one of the present patentees, namely, Richard Heathfield, is a partner.
The Provisional Specification of the said Patent describes the nature
of the Invention in the following words :-
"This Invention has for its object improvements in coating sheets of
"metal with other metals and other substances.
<
"
"Heretofore sheets of metal have been coated by dipping them
separately into the molten metal or other fluid substances used for
coating, and it is well known that for various purposes lengths of
"coated sheet metal are required greater than the length of a single
sheet, and that in such cases it has been usual to connect several
"sheets together by grooving, linking, rivetting, or otherwise after
they have been separately coated with the metal or other coating
"substance. Now my improvements consist in combining sheets of
"iron or of other metal together at their edges by any of the ordinary
"means above mentioned before they have been coated, or such con-
necting of the sheets together may be only temporary where it is
desired simply to obtain the advantages of a more continuous process
"of dipping a series of plates or sheets into a coating fluid. The joined
or connected series of plates or sheets are then immersed in succession
"into the bath of melted metal or other substance with which they
are to be coated, by which means not only will the general surfaces
"be coated, but the permanent joints will also be coated, and the joints
or seams thereby more advantageously made, and at the same time
"the connecting of several sheets or plates together before coating
"them will facilitate their being moved into and from the melted
coating metal or substance, and will also facilitate the movement of
"
$6
a succession of plates or sheets into and through a hot chamber in
"order that they may become heated and be caused in passing out of

page_text: "
"
"
"the hot chamber to enter the flux (floating on the bath of coating
metal) in a more highly heated state, whereby the coating of the
"sheets or plates in some cases will be more effectually accomplished.
By thus joining or connecting together numerous sheets or plates
of iron or other metal the manufacturer will be enabled to supply
"his customers with great lengths of coated sheet metal, from which
may be cut any desired lengths, and the manufacturer will by con-
"necting the sheets or plates either permanently or temporarily be
advantaged by rendering the process of coating more continuous as
".compared with the coating of sheets or plates separately."

Our Invention consists in coating the sheets to. be joined with a
preliminary coating of metal before they are connected together and
passed through the bath of melted metal by which the final and con-.
tinuous coating is to be given to them.. By this preliminary coating
the junction of the shects or plates is in some cases more efficiently
made than in the case of sheets or plates without a preliminary coating ;.
for example, when the ends of the plates are connected together in such
a way as to prevent the melted metal of the final coating from entering
between them the preliminary coating is melted and effects the junction
or soldering together of the plates. The preliminary coating is especially
applicable to the manufacture of connected sheets of iron coated with
tin or terne metal, but we do not limit ourselves to any particular
coating metal or alloy..
In applying the preliminary coating the sheets may either be coated
with the said preliminary coating over their whole surface, or only such
portions of the edges of the sheets may be coated as are bent or
otherwise made use of for effecting the junction of the sheets. In
general we prefer to effect the preliminary coating by the use of a
melted metal or alloy of the same kind as that with which the final
coating of the continuous sheet is to be effected, but we do not limit
ourselves thereto, as a different metal or alloy may be employed..
As the process of coating and the coating bath and apparatus em-
ployed in effecting the said preliminary coating are the same as those
ordinarily employed in coating sheets or plates of metal, we therefore
do not consider a description of the same necessary.
The process of coating the joined or connecting sheets is the same as
in Whytock's Patent, herein-before referred to.

page_text: Having now described the nature of our Invention, and the manner
in which the same is to be performed, we wish it to be understood that
we claim as our Invention, the improvements herein-before described in
coating sheets of metal with other metals, that is to say, coating with a
preliminary coating the whole or part of the surface of the sheets or
plates of iron or of other metal of which a continuous or connected sheet
is to be made before the said sheets or plates are connected together and
passed through the bath of melted metal by which the final and con-
tinuous coating is to be given to them, for the purpose and substantially
as herein-before described.
In witness whereof, I, the said Richard Heathfield, have hereunto
set my hand and seal, this Twenty third day of October, in
the year of our Lord One thousand eight hundred and sixty-
ninc.
