PROVISIONAL SPECIFICATION.
A New or Improved Paint for Coating Ships' Bottoms, Railway
Waggons, Piers, and the like.
J, JOHN EDWARD WILLIAMS of The Rowans, St. Clements Road, Chorlton-
cum-Hardy, Manchester, England, Paint Manufacturer, do hereby declare the
nature of iny said invention to be as follows:-
My invention has for its object the manufacture of an anti-salt paint or composi-
tion which shall be unaffected by salt-water, salt spray or vapor and therefore be
suitable for coating ship bottoms, railway waggons, piers, etcetera.
In accordance with my invention I take a quantity of india-rubber and I so treat
it that all its elasticity is destroyed. Whilst so treating the india-rubber I add
the pigment requisite for producing the color required.
I then cut this unstretchable rubber compound into small pieces and dissolve
the same in any suitable solvent, such as turpentine, solvent naptha, or petroleum
spirits. To this I add copal or other suitable gum, previously dissolved or made
liquid, and then grind the whole together, so forming the anti-salt paint aforesaid,
two per cent. of boiled linseed oil or other freeing agent being added during the
mixing.
The proportions in which I prefer to mix the several ingredients of my anti-
salt paint are about as follows.
1 lb. of india-rubber, 20 lbs. of turpentine, 12 lbs. of gum and two per cent. of oil,
the quantity of pigment being according to shade and body of color required.
Dated this 21st day of March 1894.
A New or Improved Paint for Coating Ships' Bottoms, Railway
Waggons, Piers, and the like.
I, JOHN EDWARD WILLIAMS of The Rowans, St. Clements Road, Chorlton-
cum-Hardy, Manchester, Paint Manufacturer, do hereby declare the nature of my
said invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
My invention has for its object the manufacture of an anti-salt paint or composi-
tion which shall be unaffected by salt water, salt spray or vapor and therefore be
suitable for coating ship bottoms, railway waggons, piers, and the like.
In accordance with my invention I take a quantity of india-rubber and by passing
such india-rubber, previously masticated, between rollers I render it non-elastic in
the well known manner. Whilst so treating the india-rubber I add the pigment or
coloring matter for producing the desired color of paint by sprinkling and spreading
it over the surface of the india-rubber previous to its passing between the rollers.
I then cut this unstretchable rubber compound into pieces and dissolve the same in
any suitable solvent such as turpentine, solvent naptha, or petroleum spirits. To
Price 8dı

page_text: this I add a varnish made from copal or other suitable gum and then grind the
whole together with the addition of about 2 per cent. of boiled linseed oil, or other
freeing agent, so producing the anti-salt paint aforesaid.
All objects coated with this improved paint or composition are effectually
protected from the corrosive action of salt water and owing to the peculiar treatment
of the india-rubber the paint is easily and evenly imparted to the surface being
coated, a feature not possessed by paints hitherto made for the aforesaid purposes.
The proportions in which I prefer to mix the several ingredients of my anti-
salt paint are about as follows:-1 lb. of non-stretchable india-rubber, 20 lbs. of
turpentine, 12 lbs. of gum and 2% of oil, the quantity and kind of pigment or
coloring matter being according to the body and color of paint required.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is :-
The use and employment of india-rubber treated and combined with the several
ingredients or substances aforesaid for producing an anti-salt paint or composition
substantially as hereinbefore set forth.
