PROVISIONAL SPECIFICATION.
Improvements for the Protection from Corrosion and Preservation
of Iron, Steel, and other Metallic Surfaces.
I ALEXANDER RYRIE of No. 7 Church Street Hebburn R.S.O. County of
Durham do hereby declare the nature of this invention to be as follows:-
An improved composition for the protection from corrosion and preservation of
iron, steel, and other metallic surfaces such as the inside of ships, ships bottoms,
tanks or other vessels for containing water or other bodies or structures requiring
to be isolated from water or moisture, and the manner in which the same is to
be applied to be as follows.
The following are the ingredients of this improved composition namely.
No. 1 Trinidad pitch,
No. 2 Stockholm pitch,
No. Burgandy pitch,
No. 4 Coal tar,
No. 5 Turpentine,
No. 5 Boiled .oil,
No. 7 Mastic,
No. 8 Ground charcoal,
No. 9 Ground pumice stone.
In the first place I make a solution by placing 'No. 4 in a large pot or boiler and
warm up to boiling heat, and keep boiling continuously for a period of 36 hours
during the last hour I add No. 3 which has been dissolved in No. 6 and then allow
the solution to cool down to 60 degrees Fahrenheit, 1 then add No. 5 when the
solution is ready to be applied with a brush either hot or cold (hot preferred) or
may be placed in drums until required and applied with a brush as first or
primary coat.
In the second place I take Nos. 1, 2, 4 and dissolve them in a large boiler over
a slow fire, taking care to keep them well stirred all the time to prevent burning,
when the whole is in a liquid state I take Nos. 7, 8 & 9, which has been previously
mixed together and place them in a very fine sieve (say 250 meshes per inch) over
the boiler thus allowing the contents to fall gently through the sieve and 'to
become thoroughly incorporated, and then boil the whole for 12 hours when it is
ready to be applied as a second coat or covering over the coating of solution,.or
it may be casked or put up in blocks and again melted as required for use and
applied hot with a brush, or may be poured on to the required thickness upon flat
surfaces.
Dated this 27th day of October 1894.

I ALEXANDER RYRIE of 7 Church Street Hebburn R.S.O. County of Durham,
Foreman Painter 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 :-
An improved composition for the protection from corrosion and preservation of
iron, steel, and other metallic surfaces such as the inside of ships, ships bottoms,
tanks or vessels for containing water, or other bodies or structures requiring to be
isolated from water or moisture.
The composition consists of the ingredients hereinafter named, the proportions
annexed thereto are calculated by weight and are, those I find to answer best in
pratise, although I do not confine myself to the proportions given as it will be
understood that the same may be varied without departing from my invention.
The following are the ingredients of this improved composition namely
No. 1 Trinidad pitch
"
2 Stockholm pitch
"
3 Burgandy pitch
4 Coal tar
"
"
5 Turpentine
"3
6 Boiled oil.
7 Mastic
وو
ور
8 Ground charcoal
وو
9 Ground pumice stone.
In place of Nos. 7, 8, 9 fine fresh water sand which has been burned in a
furnace, dry cements or oxide of iron may be used, but I prefer Nos. 7, 8, 9 as
being bulk for bulk lighter than the others. According to one part of my
invention, I cover by laying on with a brush an adhesive coating or solution which
is prepared by placing 4 parts of No. 4 in a large pot or boiler and warm up to
boiling heat and keep boiling continuously for a period of 36 hours during the last
hour I add 2 parts of No. 3 which has been dissolved in 1 part of No. 6 and then
allow the solution to cool down to 60 degrees Fahrenheit. I then add part of
No. 5 when the solution is ready to be applied either hot or cold (hot preferred) or
may be placed in drums until required and applied with a brush as a first or
primary coat.
According to another part of my invention I take 2 parts of No. 1, 1 part
No. 21 part No. 4 and dissolve them together in a large boiler over a slow fire
taking care to keep them well stirred all the time to prevent burning when the
whole is in a liquid state, I take part of No. 7, 2 parts No. 8, part No. 9
which has been previously mixed together, and place them in a very fine
siere (say 250 meshes per inch) over the boiler, thus allowing the contents to fall
gently through the sieve and to become thoroughly incorporated and then boil the
whole for 12 hours when it is ready to be applied as a second coat or covering over
the coating of solution, or it may be casked or put up in blocks and again melted
as required for use and applied hot with a brush or poured on to the required
thickness upon flat surfaces.

page_text: Having described the nature of my said invention and explained the manner of
carrying it into practical effect, I would have it understood that what I consider
new and original and therefor claim as my invention is
1st. The adhesive coating or solution prepared substantially as described and
applied as herein set forth.
2nd. The coating or covering of iron, steel, or other metallic surfaces with a
composition prepared substantially as described and applied in conjunction with
the adhesive coating or solution.
Dated this Fifteenth day of July 1895.
