Metal Structures from Corrosion, land Apparatus for the
Application of the same.
We, EDMUND FREDERICK Wailes, Naval Architect, and EDWARD John Dove,
Cement Manufacturer, both in the City and County of Newcastle-upon-Tyne, do
hereby declare the nature of this invention to be as follows:-
Our invention consists of an asphaltic solution, also of an asphaltic composition to
be applied; the former with a brush preferably in a slightly warm state, and the
latter with a brush in a hot liquid state, in one or inore coatings, to the various
structural parts, made and applied in the manner hereinafter described.
The solution consists of spirits of naptha with natural or manufactured asphalto,
and grease, or oil, mixed and incorporated by boiling in a caldron and when cool run
into casks, the following are about the proportions we prefer the solution to consist
of viz.: about 1 cwt. asphalte, 20 gallons spirit naptha and about 28 lbs. of grease.
The composition consists of natural or inanufactured asphalte and pitch melted in
a caldron along with Portland cement, lime, chalk or other suitable ingredients added
to give body and strength to the composition these being thoroughly incorporated
are run off into moulds and cast into suitable blocks, the following are the pro-
portions we prefer the asphalte composition to consist of viz.: about 1 cwt. of
asphale, 50 lbs. of pitch, 25 lbs. of chalk, 35 lbs. of Portland cement, and 1 gallon.
of oil.
The structures are primarily coated with the solution by brushing in the ordinary
way and when dry we apply one or more coatings of our asphalte composition whilst
hot by brushing in the same way as ordinary painting.
The apparatus consists principally of a special paint can of about 4 gallons capacity
put loosely into a chamber or casing that surrounds the can, this can and chamber
are made preferably of steel but can be made of any other material, the contents of
the can are heated with a spirit lamp placed underneath the can inside the chamber.
The lamp we prefer consists of 3 or more large burners protected with wire gauze

page_text: funnels. A small safety valve or escape pipe is fitted on the lamp to prevent the
spirit or oil exploding: Or the can may be heated by other means such as coal,
coke or charcoal, fire or by gas. The appliance is portable and of light construction
so as to be easily moved about by hand and weighs about 25 lbs. complete. The
method we prefer for applying the solution or composition is, first, to coat the
structure with the solution and, when this coating is dry, the composition blocks are
dissolved in a large caldron or. boiler upon the ground; and conveyed in buckets on
to the staging or scaffolding and poured into the special heated paint can alongside
of the structures, the composition may then be applied by the workmen at leisure with
brushes while hot in one or more coats.
.Compositions for the Coating and Preservation of Iron, Steel, or
Metal Structures from Corrosion, and Apparatus for the
Application of the same:
We, EDMUND FREDERICK WALLES, Naval Architect and EDWARD JOHN DOVE,
Cement Manufacturer, both in the City and County of Newcastle upon Tyne, do
hereby declare the nature of said invention and in what manner the same is to 2
be performed to be particularly described and ascertained in and by the following
statement:—
Our invention "consists of an asphaltic solution, also of an asphaltic composition to
be applied; the former with a brush preferably in a slightly warm state, and the
latter with à brush in a hot liquid state, in one or more coatings, to the various 2
structural parts, made and applied in the manner bereinafter described.
.The solution consists of. spirits. of naptha with natural or manufactured asphalte
and grease, or oil, mixed and incorporated by boiling in a caldron and when cool run
into casks, the following are about the proportions we prefer the solution to consist
of viz. about 1 cwt of asphalte, 20 gallons spirits of naptha and about 28 lbs. of grease a
or oil.
The composition consists of natural or manufactured asphalte and pitch melted
with grease or oil in a caldron along with portland cement, lime, chalk or other
suitable ingredients added to give body and strength to the composition with pre-
ferably the addition of a small proportion of resin. These being thoroughly

page_text: incorporated are run off into moulds and cast into suitable blocks, the following
are the proportions we prefer the asphalte composition to consist of viz.: about 1 cwt.
of asphalte, 50 lbs. of pitch, 25 lbs. of chalk, 35 lbs. of portland cement and 1 gallon of
oil and about 7 lbs. of resin.
The structures are primarily coated with the solution by brushing in the ordinary
way and when dry we apply one or more coatings of our asphaltic composition whilst
hot by brushing in the same way as ordinary painting.
The apparatus for applying the compositions, of which a drawing is given, consists
principally of a special paint can A of about 4 gallons capacity put loosely into a
chamber or casing B that surrounds the can, this can and chamber are made preferably
of steel but can be made of any other material, the contents of the can are heated,
with a spirit or oil lamp C placed underneath the can inside the chamber. The lamp
we prefer consists of 3 or more large burners protected with wire gauze funnels.
A small safety valve or escape pipe D is fitted on the lamp to prevent the spirit or oil
exploding. Or the can may be heated by 'other means such as coal; coke or charcoal,
fire or by gas. The apparatus as shewn is portable and of light construction so as to
be easily moved about by hand and weighs only about 25 lbs. complete. The method
we prefer for applying the solution or composition is, first, to coat the structure
with the solution and, when this coating is dry, the composition blocks are
dissolved in a large caldron or boiler upon the ground, and conveyed in buckets
on to the staging. or scaffolding and poured into the heated paint can of the
apparatus alongside of the structures, the composition may then be applied by the
workmen at leisure with brushes while hot in one or more coats.
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:―
1st. The manufacture of asphaltic compositions in the form of solution or into solid
blocks consisting in each case of the ingredients specified, in about the proportions
stated, and the treatment and application of the same for the coating of iron, steel or
metal structures to preserve them from corrosion substantially as described.
2nd. The portable apparatus for the convenient preparation of such compositions for
application to the surfaces to be coated substantially as described and shown by
drawings.
