PROVISIONAL SPECIFICATION.
An Improved Method or Process of Treating Steel, Iron, or any Com-
bination of such Metals, to Prevent their Oxydising, Rusting,
or Corroding.
1 THOMAS WILLIAM HELLIWELL of Brighouse, in the County of York, Civil
Engineer do hereby declare the nature of this invention to be as follows:-
The object of my invention is to subject steel, iron or any combination of such
metals, to a process for the purpose of preventing the oxydization or corrosion of the
said metals, so as to render them thoroughly impervious to the action of the weather,
water, foul atmosphero or other causes injurious to metals.
In carrying out my invention I prefer a mixture composed of boiled oil, mutton fat
and turpentine, or similar compounds, all being mixed together in suitable proportions.
The metal to be treated is first cleaned and heated in a stove or other place to a
suitable temperature, and afterwards immersed in the said mixture, which the heated
metal readily absorbs, and after remaining in the mixture a suitable length of time,
the said metal is removed and may be allowed to dry, but I prefer to place the said
metal into a stove or other chamber heated to a low degree, so that the mixture may
set and harden on the metal. If necessary the metal may be again immersed in the
mixture and dried as already described, whereby two or other number of coats may be
applied to the metal.
As the heating of the metal expands, it opens the pores therein and readily absorbs
the mixture which penetrates the fibre of the metal covering it with a bright, smooth,
and varnish-like surface, rendering it thoroughly impervious to the action of water
and all destructive atinospheres. Metals treated in this manner require no paint but
the coated metal will readily take paint if desired.

COMPLETE SPECIFICATION.
An Improved Method or Process of Treating Steel, Iron, or any Com-
bination of such Metals, to Prevent their Oxydising, Rusting,
or Corroding.
1 THOMAS WILLIAM HELLIWELL, of Brighouse in the County of York, Civil
Engineer, 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 :-
The object of my invention is to subject steel, iron, or any combination of such or
other metals, to a process for the purpose of preventing the oxydization or corrosion
of the said metals so as to render them thoroughly impervious to the action of the
weather, water, foul atmosphere or other causes injurious to metals.
In carrying out my invention I prefer a mixture composed of oil, mutton fat
and turpentine, all being mixed together in the following proportions, riz :-if
making one gallon of such mixture, I may use 6 pints of oil, 1 pint of fat, and
1 pint of turpentine; but these proportions will vary according to the work for
which they are used. The metal to be treated is first cleaned and heated in a
stove or other place to about 600 degrees. The metal is afterwards immersed in
the said mixture, which is readily absorbed by the heated metal, and after remaining
in the mixture, say from 5 to 15 minutes, according to the thickness, the said
metal is removed and may be allowed to dry without any aid; but I prefer to

page_text: place the said metal into a stove or other chamber heated to not more than
400 degrees, so that the mixture may set and harden on the metal. If necessary
the metal may bo again immersod in the mixture and dried as already described,
whereby two or other number of conts may be applied to the metal.
As heating the metal causes it to expand, the pores are opened therein, which
readily absorbs the mixture and penetrates the fibre of the metal, covering it with
a bright, smooth, and varnish like surfaca, rendering it thoroughly impervious to
the action of water and all destructive atmospheres. Metals treated in this manner
require no paint, but the coated metal will readily take paint. if desired.
The treating of metals as herein described will be found very advantageous when
applied to taps and valves, whether employed for steam, water, or chemical purposes,
as the treatment will prevent the metal from fouling or corroding.
Having now particularly described and ascertained the nature of my said
invontion, and in what mannor the same is to be performed, I declare that what
I claim is :-
The method or process of treating metals in manner substantially as herein
described and for purposes set forth.
