COMPLETE SPECIFICATION.
An Improved Enamel Paint and Method of Applying the same.
We, FREDERICK BOYLING, of Merton Street, Brisbane, in the Colony of Queensland,
Inventor, CHARLES LANCELOT GARLAND, Gentleman, and ALEXANDER OGDEN,
Contractor, both of 156 Vickery's Chambers, 82, Pitt Street, Sydney, in the Colony
of New South Wales, do hereby declare the nature of this inventon and in what
manner the same is to be perforined, to be particularly described and ascertained in
and by the following statement :—
The improved enaeml paint which forms the subject of the present invention, is
composed of certain well known ingredients that are mixed together and applied in a
particular manner the finished surface that is presented being lustrous and combining
within itself the qualities of hardness, toughness, flexibility, and resistance to a fairly
high temperature of fire or heat.
This improved enamel paint may be applied to any substance such as metals, wood,
glass, earthenware, terra cotta, stone and brick work, leather or the like.
The ingredients of this improved paint when used for any substance other than
leather are four in number; viz.-Powdered shell-lac, methylated spirits, any suitable
ground coloured pigment, and coach or carriage varnish, the mode of manufacture
being as follows;-1st Dissolve the powdered shell-lac in the methylated spirits, in
proportion 1 oz. of the former to 1 pint of the latter, this solution is technically called
bindings," 2nd any finely ground and suitable coloured pigment those sold as coach
painter's colours ground in Japan or gold size are preferable.
3rd. Mix the coloured pigment with varnish (coach or carriage being preferable) to
a thin paste using as little varnish as possible, and then to every pound or pint of this
paste add 3 oz. of the "bindings," and stir well together so as to thoroughly co-mingle,
then add sufficient varnish coach or carriage being preferred, to thin the mixture to
such a consistency that it may be used with a brush. It may then be packed in tins
or jars ready for sale.
In
4th. If the enamel paint is to be used for coating leather, to each pint of the paint
made in the manner above described should be added 2 oz. of raw linseed oil.
applying this improved enamel paint it is necessary in order to obtain the best results
that the article to be coated should be free from grease or other matter, which might
prevent the enamel paint from adhering.
Should this improved enamel paint be applied to any article or articles that it may
be convenient to submit to a high temperature in an oven or closed chamber a very fine,
smooth and hard surface is obtained in the following manner;--If the article be com-
posed of metal, after receiving a coat of paint it should be baked in a suitable oven
or closed chamber for a space of about two hours, at a temperature of about
250 degrees (Fah.), and if any more than one coat is applied the article should be
baked a second time in the same manner and if a very high finish is desired a
finishing coat of good varnish may be applied, and the article baked as before.
When the article to be coated consists of leather the special preparation containing
the admixture of raw linseed oil should should be used, and the article submitted in an
oven or closed chamber to a heat not exceeding 125 degrees (Fab.). If either of the
above temperatures be too high so that the material of which the article is composed

page_text: would suffer, then the article must be baked in a lower temperature but for a longer
time. This improved paint may be applied to any article or substance that is suitable
to receive a coat of any paint and it may be applied with a brush and allowed to dry
and the article will then present a smooth and hard surface without being submitted
to the baking process above described. It may be applied to ship's bottoms as it is
anti-fouling; it may also be applied to all classes of machinery, and to iron work on
board ship it being anti-corrosive. In using this improved paint it will be found that
if properly applied one coat will be sufficient instead of the usual three coats of oil
and lead paint, it will stand great heat or cold, and will not blister, chip or crack,
but will be very hard and at the same time tough, presenting a very brilliant
appearance.
Several qualities of this improved paint may be made by using for best
quality coach painters colours ground in Japan or gold size, and mixing with
best carriage varnish; for second qnality substitute cominon varnish for best carriage
varnish; for third quality use common powdered colours, mix with common varnish
and grind in a paint mill and mix as before. This latter quality is suitable for rough
work such as pipings, brick or stone work, or any work that is placed underground
or out of sight.
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;-
1. The herein described improved enamel paint, consisting of a mixture of shell-lac,
methylated spirits, coloured pigment and varnish, in the proportions and mixed in
the manner herein specified.
2. The herein described improved enamel paint for leather consisting of a mixture
of shell-lac, methylated spirits coloured pigment, varnish and raw linseed oil in the
proportions and mixed in the manner herein specified.
3. Applying the herein described improved enamel paint, consisting of a mixture
of shell-lac, methylated spirits, coloured pigment, varnish, with or without the
admixture of raw linseed oil, in the proportions and prepared as herein set forth, to
the surface of the article to be coated and then subjecting the article to a suitably
high temperature in an oven or closed chamber as specified.
