PROVISIONAL SPECIFICATION.
Improvements in the Coating and Ornamenting of Iron and other
Metallic Surfaces.
I, JOHN HARRINGTON, of Claremont, West Street, Ryde, in the Isle of Wight,
Manufacturer, do hereby declare the nature of this invention to be as follows:-
The invention has for its object a new or improved method of coating and
ornamenting iron and other metallic surfaces by which means I can produce an
imitation leather or other desired surface.
For this purpose I thoroughly clean the metal and then apply a coating of suitable
waterproof size. When this coating has partially set but has still an adhesive or
"tacky" surface, I dust over the same ground flock, cork, wood dust or other suitable
absorbent fibre or material, separately or in any suitable combination, which is
rolled or pressed upon the size so as to effect thorough union therewith. I then
repeat the process any desired number of times.
The several coatings are colored by any desired coloring matter combined with the
size or worked into each individual coating or dressing.
When a sufficient thickness or body is attained, the article so coated is submitted
to a gentle drying heat and, when sufficiently hard, the surface may be submitted to
direct pressure or to a burnishing action.
The surface above obtained is capable of receiving any suitable leather dressing
such as is used for ordinary harness, either in color or black, and can be treated by a
groom in the ordinary way of treating leather harness; or the surface obtained can
be enamelled in imitation of enamelled leather, or otherwise treated to obtain any
desired appearance.
Improvements in the Coating and Ornamenting of Iron and other
Metallic Surfaces.
I, JOHN HARRINGTON, of Claremont, West Street, Ryde, in the Isle of Wight;
Manufacturer, 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 invention has for its object a new or improved method of coating and
ornamenting iron and other metallic surfaces by which means I can produce an
imitation leather or other desired surface.

page_text: For this purpose I thoroughly clean the metal and free it from scale, I then apply
a coating of suitable waterproof size, preferring for that purpose what is known as
Japanese gold size. When this coating has partially set but has still a sufficiently
adhesive or "tacky" surface I dust it over with ground flock, cork, wood dust or
other suitable absorbent fibre or material separately or in any suitable combination,
ground wool preferably black being found to answer the purpose well. I also roll or
I then
press these materials upon the size so as to effect thorough union therewith.
stove it for about 2 hours at a temperature of from about 160° to 180° Fahrenheit.
When thoroughly hard I proceed to give the metal a further dressing prepared as
follows:-
I take any good japanners stoving varnish and mix with it sufficient vegetable
black to make it thoroughly opaque-2 ozs. vegetable black to one pint of varnish is
found to be a suitable preparation.

"
With this mixture I further coat the metal two, three or more times according to
the thickness of coating required, sifting over each coat whilst wet or tacky
ground wool or other suitable fibre or material, the object of which is to make a
fibrous body, the fibre tying the substance together and making it much less likely
to chip.
Each coat may be pressed or rolled to ensure the union of the fibre or other
material with the varnish and is then stoved for about 3 hours after which it is rubbed
down with pumice stone to smooth its surface for the next coat.
When a sufficient thickness or body is attained upon the metal I give it a last coat
of like varnish, mixing about 1 oz. of best gas black or the like with one pint of
varnish. This coat is stoved for about 3 hours, rubbed down and if the finished
article is to have the appearance of harness leather, it is dressed with ordinary
harness paste and brushed up, or it may be French polished in the ordinary way
of French polishing, the rubber being charged from time to time by dipping it into
the powdered gas black.
The result of this final treatment is a very beautiful black lustre.
If other color than black be required, the several coatings are colored by any
desired coloring matter combined with the size or varnish or worked into each
individual coating or dressing.
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 method of coating and ornamenting iron and other metallic surfaces,
substantially as herein set forth.
2. The improved method of coating and ornamenting metal surfaces consisting in
cleaning the same, applying a coating of suitable waterproof size or varnish and
when this coating has partially set, dusting it over with a suitable absorbent fibrous
material rolling or pressing the material upon the size or varnish and gently
stoving the same the said operations being repeated as many times as is necessary
to produce the required surface substantially as herein described.
