IMPROVEMENTS IN COMPOSITIONS FOR SHIPS AND IN THE METHOD OF APPLYING THE SAME
Year: 1884

page_text: I WILLIAM DAY of Arreton Blackheath in the County of Kent Manufacturer
of Cements, do hereby declare the nature of my Invention for "IMPROVEMENTS
IN COMPOSITIONS FOR SHIPS AND IN THE METHOD OF APPLYING THE SAME, to
be as follows :—
Paints and varnishes hath hitherto been applied to the inside and outside plates
or surfaces of ships caissons watertanks and the like things for the purpose of
protecting the surface and as a substitute for and an improvement upon such paints
and varnishes I claim to apply to such ships caissons watertanks and the like
things two or more coatings which I make and use in the following manner.
In the first instance apply a preparatory and first coating of crude spirits of
naptha or other similar spirit to penetrate the pores of the steel iron or wood
surfaces, before applying the composition such first coating is applied with a brush
and after the spirit is partly absorbed into the pores of the surface.
Second I then put on a composition consisting of the following ingredients
namely india rubber and naptha rosin and tar mixed together to which I add
granulated pitch Portland or other cement. I dissolve the india rubber in the
naptha. The resin I melt by heat and afterwards mix tar therewith. I add thereto
the dissolved india rubber and naptha. Thereto, I add granulated pitch and
Portland cement or in lieu thereof Roman cement lime or other like powdered
ingredients may be used. The aforesaid composition is also put on with a
The above is used for the inside and outside of ships and the other things
before mentioned.
brush.
I do not bind myself to any particular quantities of the above materials but I
generally use four pints of crude spirits of naptha or similar spirit in which I
dissolve one ounce of india rubber, I then take 4 lbs. weight of rosin and melt it
by heat and thereto add when cooling two pints of coal tar to which I add the
dissolved india rubber and naptha. I then take one pound of granulated coal
pitch and one pound of Portland cement and mix them together. These quantities
may be varied more or less, as preferred.
The Portland cement or other like powdered product may be omitted but then
the composition has not so much body.
In the third place after the composition as aforesaid is applied a coating
consisting of a layer of hot asphalte for the inside bilge bottom plates and rivetheads
of ships may be used or not as desired.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is,
1. The composition substantially as herein before described.
2. The method of its application over a preparatory or first coating of crude
spirits of naptha or other similar spirit as herein before described.
3. For the inside of ships and other things hereinbefore mentioned the application
when desirable of an additional coating of a layer of hot asphalte over the
aforesaid composition.

I WILLIAM DAY of Arreton Blackheath in the County of Kent Manufacturer
of Cements do hereby declare the nature of my Invention for IMPROVEMENTS IN
COMPOSITIONS FOR SHIPS AND IN THE METHOD OF APPLYING THE SAME, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
Paints and varnishes have hitherto been applied to the inside and outside plates
or surfaces of ships caissons water tanks and the like things for the purpose of
protecting the surfaces. Now as a substitute for and an improvement upon such
paints and varnishes I apply to such ships caissons water tanks and the like things
two or more coatings which I make and use in the following manner.
In the first instance I apply a preparatory and first coating of crude spirits of
naptha or other similar spirit this penetrates the pores of the steel iron or wood
surfaces before the second coating or composition is applied, this first coating is
applied with a brush.
2. After the spirit is partly absorbed into the pores of the surface and whilst
yet stickey I put on a composition or second coating. This consists of the following
ingredients namely india rubber and naptha rosin and tar mixed together to which
I add granulated pitch and Portland or other similar cement lime or powered
oxide of iron or light metallic powder. I dissolve the india rubber in the naptha.
The rosin I melt by heat and then mix tar with the dissolved rosin. I then add
thereto the dissolved India rubber and naptha and having mixed the aforesaid
things together I add granulated pitch and Portland cement lime or other like
powdered ingredient herein before mentioned. I do not bind myself to any particular
quantities of the above materials but I generally use four pints crude spirits of
naptha or similar spirit in this I dissolve one ounce of india rubber. I then take
4 lbs. weight of, rosin and melt it by heat and thereto add when cooling two pints
of coal tar to which I add the dissolved india rubber and naptha: I then take one
pound of granulated coal pitch and one pound of Portland cement or other
powdered ingredient and mix them together. These quantities may be varied
more or less as preferred. The Portland cement or other like powdered product
may be omitted but then the composition has not so much body. The aforesaid
composition is also put on with a brush. The above is used both for the inside
and outside of ships and other things before mentioned.
3. In the third place after the composition as aforesaid is applied a coating
consisting of a layer of hot asphalte for the inside bilge bottom plates and rivet
heads of ships may be used or not as desired the two first coatings form a protection
to the steel iron or wood and the third coating or asphalte an additional protection
to the parts for which it is used.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. The composition substantially as hereinbefore described.
2. The method of the application over a preparatory or first coating of crude
spirits of naptha or other similar spirit as herein before described.
3. For the inside of ships and other things mentioned the application when
desirable of an additional coating or layer of hot asphalte over the aforesaid
composition.
