I, ALEXANDER PARKES of 32 Park Road, West Dulwich in the County of
Surrey, Chemist do hereby declare the nature of said Invention for "IMPROVE-
MENTS IN THE PRODUCTION OF COMPOUNDS FOR COATING OR COVERING AND
PROTECTING METALLIC VEGETABLE OR OTHER SURFACES to be as follows:-
"
This Invention relates to the production of compounds which are capable of being
used either as a thick permanent coating or covering or in a thin form for application
as ordinary varnish is applied and it consists in the use of Carbolic acid by
preference when in a crystallized or solid condition either alone or in conjunction
with camphor as a new and novel solvent for gum resin fat or fatty acids such as
India rubber, Gutta Percha, Copal, Japanese, Paraffin or other Wax or other
equivalent Animal, Vegetable or Mineral fatty or oily matters such as Asphaltum
or Bitumenous or pitchy matters or products derived from the distillation of Coal
or shale.
In carrying out my Invention I take Carbolic acid (by preference in a crystallized
condition) and with or without the admixture of Camphor in the proportion from
about 10 parts by weight of anhydrous Carbolic Acid or of Camphor and Carbolic
acid in admixture and from about 10 to 20 parts by weight of one or of mixtures
of two or more of the gummy resinous fatty or oily substances or products before
mentioned as being used in conjunction with the Camphor or Carbolic Acid or
both.
These materials (by preference in a fine state of division) are placed in a suitable
vessel and are thoroughly incorporated either by agitation or otherwise, either at
the ordinary temperature or at an elevated temperature ranging from about 360°
to about 375° Fahrenheit to effect their liquefaction.
The product thus resulting will be found suitable for being employed for the
purposes herein before mentioned either as a thick coating or covering or as a thin
covering which may be applied as varnish is applied. In order to render the
materials capable of being applied with facility in the latter way I prefer to thin,
them with Turpentine, oils or oleagenious products or drying oils such a Linseed
Din 471

of Carbon Benzole and such Hydrocarbons as are mixible with the materials and
will reduce them to the required degree of thinness to allow of their being applied
as ordinary varnish is applied.

I ALEXANDER PARKES of 32 Park Road West Dulwich in the County of
Surrey Chemist do hereby declare the nature of my invention for "IMPROVEMENTS
IN THE PRODUCTION OF COMPOUNDS FOR COATING OR COVERING AND PROTECTING
METALLIC VEGETABLE OR OTHER SURFACES" and in what manner the same is. to
be performed, to be particularly described and ascertained in and by the following
statement:
This Invention relates to the production of compounds which are capable of
being used either as a thick permanent coating or covering or in a thin form for
application as ordinary varnish is applied and it consists in the use of carbolic acid
(by preference when in a crystallized or solid condition) in conjunction with
camphor to form a solvent for gum resin fat or fatty acids such as India rubber,
Gutta Percha, Copal, Japanese or Paraffin or other wax or other equivalent animal
vegetable or mineral fatty or oily matters such as Asphaltum or Bituminous or
pitchy matters or products derived from the distillation of coal or shale.
In carrying out my Invention I take carbolic acid (by preference in a crystallized
condition) and mix therewith camphor in the proportion of about equal parts or
until the carbolic acid is saturated with camphor and I add to this mixture one or
more of the gummy resinous fatty or oily substances or products before mentioned
as being used in conjunction with the Carbolic Acid and Camphor-The proportion
of the mixture of carbolic acid and camphor to the other substances mentioned
(one or more of them) may be about ten parts by weight of the former to from
10 to 20 parts of the latter.
The ingredients (by preference in a fine state of division) are placed in a suitable
vessel and are thoroughly incorporated by agitation or otherwise either at the
ordinary temperature, or at an elevated temperature ranging from about 300 degrees
to about 825 degrees Fahrenheit to effect their liquefaction.

purposes hereinbefore mentioned either as a thick coating or covering or as a thin
coating or covering which may be applied as varnish is applied. In order to render
the compound capable of being applied with facility in the latter way I prefer to
thin it with Turpentine oils or oleagenious products or drying oils such as linseed
oil or with alcohol methylated spirit naptha Bisulphide of Carbon, Tetra-Chloride
of Carbon, Benzole or such other Hydro carbons as are mixible with the compound
and will reduce it to the required degree of thinness to allow of its being applied
as ordinary varnish is applied.
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
The manufacture and use of compounds for the protection of surfaces the said
compounds being prepared by dissolving gums or substances of the nature herein-
before defined in or with a mixture of Carbolic acid and camphor substantially as
herein before described.
