We, JOHN TAYLOR, of Wellington Terrace, Dudley Road, Wolverhampton, in
the County of Stafford, iron-plate worker, and JEREMIAH TAYLOR, of Poplar
Cottage, Parkfield Road, Wolverhampton, aforesaid, iron-plate worker, do hereby
declare the nature of our invention for IMPROVED MEANS FOR PREPARING IRON
AND STEEL SHEETS AND OTHER PARTS OR ARTICLES OF IRON OR STEEL AND
COATING THEM WITH COPPER AND ALLOYS OF COPPER, to be as follows:-
The object of this invention is to adopt means analogous to those employed for
galvanizing sheets for the purpose of preparing iron and steel sheets and other
parts or articles of iron or steel and coating the same with copper and alloys of
copper.
According to this invention the sheets or other articles of iron or steel are
pickled or prepared by immersion in a solution of borax, sulphur, or common salt,
or of any two or more of these minerals, the proportion of the whole mineral in
the solution being about, say, one pound to four gallons of water. The solution is
more effective if used hot. The sheets or other articles are then removed from the
solution and well dried, and afterwards dipped into a bath of the copper or copper
alloy in a molten state by which means they receive a coating of such copper or
copper alloy. A flux is employed composed of calcined borax, or glass, or of the
two mixed together. After removal from the bath the sheet or other article is
cleaned as in the ordinary process of galvanizing.
Sheets and plates and other parts capable of being rolled to reduce their thickness,
coated in the manner before described, inay be heated to the necessary temperature
and rolled to reduce their thickness, the coating of copper or of copper alloy
remaining thereon and being rolled therewith. Sheets or plates may of course be
cold rolled if desired.
Iron and steel wire coated in the manner before described may be drawn down
two or three gauges, if desired.
In the case of bars and ingots which it is desired shall be rolled down into plates
or sheets after being coated, such bars and ingots may be prepared for coating by
being dipped hot in molten borax or sulphur, or in a molten compound or mixture
of these two, or of either of them with common salt, or of the three ingredients
together, instead of being dipped in the solution before described; and this method
of preparation may be adopted also in the case of thick plates and bars generally
and of any strong or heavy parts or articles.

page_text: We, JOHN TAYLOR, of Wellington Terrace, Dudley Road, Wolverhampton in the
County of Stafford, iron plate worker, and JEREMIAH TAYLOR, of Poplar Cottage,
Parkfield Road, Wolverhampton, aforesaid, iron plate worker, do hereby declare
the nature of our invention for IMPROVED MEANS FOR PREPARING IRON AND
STEEL SHEETS AND OTHER PARTS OR ARTICLES OF IRON OR STEEL AND COATING
THEM WITH COPPER AND ALLOYS OF COPPER, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the following
statement
The object of this invention is to adopt means, analogous to those employed for
galvanizing sheets, for the purpose of preparing iron and steel sheets and other
parts or articles of iron or steel and coating the same with copper and alloys of
copper.
According to this invention the sheets or other articles of iron or steel are first
pickled as if for galvanizing and are then prepared by immersion in a solution of
borax consisting of about, say, one pound of borax to four gallons of water. The
solution is made with hot water, preferably of boiling temperature, and is more
effective if used hot. For the purpose of heating the water for dissolving the
borax, and also for maintaining the solution at boiling or other high temperature
during the immersion of the sheets or other articles of iron or steel therein, steam
is blown into the water and solution, or circulates through a coil or other piping
therein. The sheets or other articles, as aforesaid, remain in the solution from, say,
twenty to thirty minutes, and are then removed therefrom and dried in an
analogous manner to that in which galvanizing sheets are dried, or in any
convenient manner, and are afterwards dipped into a bath, crucible or other
suitable vessel, containing molten copper or copper alloy, by which means they
receive a coating of such copper or copper alloy.
The flux employed through which to enter sheets, rods, and analogous articles,
in order to coat them with copper or alloy of copper, consists of borax, which is
preferably previously calcined. Common salt is added from time to time to thin
this flux when it shews a tendency to thicken or set. The flux employed over the
other part of the bath or vessel containing the molten metal or alloy, namely, the
part where the sheets, rods, or analogous articles are withdrawn after being coated,
consists, preferably of glass, though borax (preferably previously calcined) may be
employed, either alone or in combination with glass (say in equal parts by weight)
if desired; or common salt may be employed as the flux. When glass or borax,
or glass and borax combined, are used for the flux for this part of the bath, common
salt is added from time to time to thin the flux as before described.
The general manipulation and working of the bath and of the flux, beyond what
is herein before described, is similar to that of galvanizing iron and steel and will
be readily understood by persons acquainted with the trade.

page_text: In the case of coating holloware and analogous articles, the flux employed consists
preferably of borax; or a mixture of borax and glass (say a quarter of a pound
of glass to one pound of borax), or common salt may be employed as the flux.
When borax, or borax and glass, is used as the flux for holloware and analogous
articles, common salt may be added from time to time to thin the flux as before
described.
Sheets or plates coated in the manner hereinbefore described may of course be
cold rolled, if desired.
Iron and steel wire, coated in the manner hereinbefore described, may be drawn
down two or three gauges, if desired.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is
1. Preparing iron and steel sheets and other parts or articles of iron or steel,
and coating them with copper, or alloy of copper, substantially in the manner
herein set forth.
2. Preparing iron and steel sheets and other parts or articles of iron and steel for
the purpose of coating them with copper, or alloy of copper, substantially in
the manner herein set forth.
3. Coating iron and steel sheets and other parts or articles of iron or steel with
copper or alloy of copper after the same have been specially prepared therefor,
substantially in the manner herein set forth.
4. Preparing iron and steel sheets and other parts or articles of iron or steel, after
the same have been pickled as described and previously to coating them with
copper or alloy of copper, by immersion in a solution of borax, substantially as
and for the purpose set forth.
5. The fluxes hereinbefore described for the purposes set forth.
