ascertained in and by the following statement:-
:-
This invention relates to a preservative composition for coating wood, metal and
the like exposed to deteriorating influences.
Our object is to provide a composition easy to apply as a cement, a paint or a
glue, cheap to manufacture, and effective for preventing rot, corrosion, fouling,
the ravages of vermin and the like tending to impair durability.
The invention consists in the combination, in substantially the proportions
stated, of the following ingredients or their equivalents:-
Tar
Resin-
2 galls.
Pitch
-
-
10 cwts.
Ground coal ashes
Creosote oil
Portland cement
-
6 cwts.
-
2 galls.
-
7 lbs.
"
Slaked lime
Kieselgur
1 cwt.
3 cwts.
7 lbs.
The proportions given are not absolute, but we recommend them as we find
them most advantageous.
To manufacture the composition, the ingredients are boiled together and
thoroughly incorporated while in the boiler, and then the mixture is poured into
receptacles or moulds to cool, the product being the composition, which is a solid
of a brittle nature and black in colour.
For use, the composition is melted, in which condition it is very viscid, next
mixed with oil to thin it, and applied with brushes or other suitable appliances;
the surface to be coated, of course, being first thoroughly cleaned.
For application to ironwork, the composition, which is popularly designated
<< cement when applied to such surfaces as the bilges and tanks of ships, and
paint" when applied to the shells and bunkers of ships and the like, is reduced
to the required working consistency by creosote or other oil. The necessary
degree of fluidity will be obvious to those skilled in the art.
The composition is applied hot, and in the case of a horizontal or like surface it
is poured on it. by buckets and brushed level, while in vertical or approximate
surfaces it is put on as in ordinary painting.
A paint to be applied cold as the first or foundation coating is obtained by still
further reducing the composition below the consistency already explained. This
is conveniently effected by the addition of creosote oil and naptha, a suitable
proportion being 10 galls. of each to every 20 galls. of the melted composition.
For woodwork, the composition, popularly called gluc," is reduced to the
required consistency by the addition of creosote or other oil, and applied hot like
paint.
In every application, the composition immediately sets and a hard glossy surface
obtains, which effectually prevents the influences above mentioned.
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 ;-
A preservative composition for coating wood, metal and the like consisting of
the herein specified ingredients or their equivalents combined together in sub-
stantially the proportions stated and prepared for use as set forth.
