PROVISIONAL SPECIFICATION.
Improved Metal Plates for the Construction of Steam Boilers, Ships,
and other Vessels.
I JOHN HENRY WANSTALL of Netherwood, Whitefield in the County of
Lancaster, Gentleman, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to manufacture improved metal plates to be used
for the construction of steam boilers ships and other analogous vessels which are
liable to incrustation, oxydation or corrosion by the action of water.
For the purposes of my invention I take plates of steel or iron and after outting
bending or otherwise forming them to the size and shapo required (and preferably
after punching the rivet boles necessary for uniting the same to each other or to
the frame of the structure), and after "pickling" or otherwise preparing the surface
thereof, I coat the plates thus fitted or adapted for use with a covoring of
copper by electro-deposition in the known manuer, until a sufficient thickness
of copper has been deposited thereon according to the use for which the plates
are intended.
1
I then construct the boiler ship or other analogous vessel by means of rivets or
bolts in the usual manner, and if thought necessary I deposit a similar coating of
copper on the rivet or bolt heads by the application locally of a bath of sulphate
of copper in connection with an electric or galvanic battery.
It will be found that steam boilers formed of steel or iron plates coated with
copper as described will not be liable to incrustation or corrosion by the action of
water thereon, and that by making, the inner and outer skin of a ship or other
analogous vessel of steel or iron plates thus coated, incrustation and corrosion both
internally and externally will be prevented.

Improved Metal Plates for the Construction of Steam Boilers, Ships,
and other Vessels:
I JOHN HENRY WANSTALL of Netherwood, Whitefield, in the County of
Lancaster, Gentleman, do hereby declare the nature of this invention 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 manufacture improved metal plates to be used
for the construction of steam boilers, ships, and other analogous vessels, which are
liable to incrustation, oxydation, or corrosion by the action of water.
For the purposes of my invention I take plates of steel or iron, and after cutting,
bending, or otherwise forming them to the size and shape required (and preferably
after punching the rivet holes necessary for uniting the same to each other, or to
Prine RI

the frame of the structure) and after " pickling" in dilute acid or otherwise
preparing the surface thereof so as to make it chemically clean, I coat the plates
thus fitted or adapted for use entirely, or ou one side only as may be preferred,
with a covering of copper hy, electro-deposition in the known manner, until a
sufficient thickness of copper has been deposited thereon according to the use for
which the plates are intended.
I then construct the boiler, ship, or other analogous vessel, by means of rivets or
bolts in the usual manner, and if thought necessary I deposit a similar coating of
copper on the rivet or bolt heads, by the application locally of a bath of sulphate
of copper in connection with an electric or galvanic battery.
It will be found that steam boilers formed of steel or iron plates coated with
copper as described will not be liable to incrustation or corrosion by the action of
water thereon, and that by making the inner and outer skin of a ship or other
analogous vessel or structure of steel or iron plates thus coated, incrustation and
corrosion both internally and externally will be prevented.
.:-
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The improved metal plates applicable for the construction of steam boilers,
ships and other vessels, manufactured as hereinbefore described, by first cutting,
bending or otherwise forming steel or iron plates to the size and shape required for
the intended structure, and then (either before or after punching or drilling the
necessary rivet or bolt holes "pickling" or otherwise preparing the surface thereof
so as to make it chemically clean, and finally coating the same (on one or both sides
thereof) with a covering of copper by electro-deposition until a sufficient thickness
of copper has been deposited thereon.
2. The improved mode of manufacture of steam boilers, ships and other vessels
consisting of preparing the plates therefor in the manner claimed in the first
claim.
