I ALEXANDER PARKES of 32 Park Road West Dulwich in the County of Surrey
Chemist, do hereby declare the nature of said Invention for "IMPROVEMENTS

-
This Invention relates to the production of Compounds capable of being
employed for coating metallic and other surfaces and consists in effecting the
solution of gums from Resins, Shellac, Resin, Drying oils or Cotton and oil
Bitumen Paraffin Campher, India Rubber Gutta Percha or other hard or soft
gums either in Carbolic acid or in Carbolic acid in conjunction with Napthaline or
with Creosote or with mixtures of the same.
In carrying out my Invention I dissolve gums or other substances in carbolic
acid (by preference when such acid is in a solid condition) either alone or in con-
junction with Napthaline or with Creosote or with mixtures of the same-I admix
either one or more of the last mentioned substances with the substances to be
dissolved in suitable vessels and cause the same to be heated up to about 300° to
400° Fahrenheit. When I employ fluid Carbolic Acid it will be found sufficient to
employ a temperature of about that of boiling water or that of a steam heat may be
employed, but several of the gums and the before mentioned can be dissolved even
when the solvent or solvents are at a lower temperature but this necessitates &
longer period the solution of the before mentioned substance or substances may be
accelerated by agitation.
If desirable I add to the compound thus resulting various other substances thus
for example as arsenical or mercurial compounds or other poisonous ingredients to
render such compound more resistent to the detrimental attacks of the Terredo or
of other destructive Agency.
When such compound or compounds is or are applied to other purposes than for
protecting ships it may not be requisite to add either of the before mentioned
poisonous compounds.
I have found that the compound or compounds resulting as before mentioned is
or are of great value in preventing the decay of wood and other perishable
substances and will be found to possess great sanitary advantages.
The substances I prefer to employ in conjunction with Carbolic acid and also in
conjunction with either napthaling or creosote in carrying out my invention are

page_text: gums, gum resins such as capal, animi, Kauri, shellac, Resin, drying oils, or cotton
seed oil, Bitumens, Asphaltum Paratin Camphor India rubber, Gutta Percha and
other hard or soft gums which are soluble in Carbolic acid or in a mixture of
Carbolic acid and Napthaline or Creosote.
I find in practice that good results may be obtained by employing about from
20 lbs of Carbolic Acid with from about 20 lbs to 45 lbs of gum kauri or any of the
substances hereinbefore mentioned.
When I wish to employ the before mentioned resulting product or products for
the purpose of coating or sheathing iron or other vessels, I employ the same either
with or without the addition of from about 2 per cent by weight to 5 per cent
by weight of any suitable arsenical or mercurial or other poisonous insoluble
compound.
When the product resulting as before mentioned is to be employed for the
purposes before mentioned I thin the compound when it is required to be more or
less fluid by employing Naptha, Turpentine, Alcohol, Benzole or oils whether
oxidized or not so as to render it more suitable and better capable of being
employed for coating metallic and other surfaces.

I ALEXANDER PARKES of 32 Park Road, West: Dulwich in the County of
Surrey Chemist do hereby declare the nature of my invention for "IMPROVE-
MENTS IN THE PRODUCTION OF COMPOUNDS CAPABLE OF BEING EMPLOYED FOR
COATING METALLIC AND 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 capable of being employed
for coating metallic and other surfaces and consists in effecting the solution of gums.
from Resins, Shellac Resin, Drying Oils, or cotton seed oil, Bitumen, Paraffin,
Camphor, India Rubber, Gutta Percha, or other hard or soft gums soluble in
Hydrocarbons, either in or with Carbolic acid, or in or with Carbolic acid in
conjunction with Naphthaline, or with Creosote or with other suitable liquid*
hydrocarbons.
In carrying out my Invention I take the gums or other substances selected, and
I also take Carbolic acid (by preference when such acid is in a solid condition)
either alone or in conjunction with Napthaline or with Creosote or with mixtures
of the same or with other hydrocarbon liquid and I admix them in suitable vessels
and cause the same to be heated up to about 300° to 400° Fahrenheit The
solution thus produced may be thinned to any degree by the addition of fluid
carbolic acid and one or more of the ordinary solvents of the gums above named
assisted by heat When I employ fluid Carbolic acid in the first instance it will be
found sufficient to employ a temperature of about that of boiling water for
dissolving, or that of a steam heat may be employed, but several of the gums or
substances before mentioned can be dissolved even when the solvent or solvents are
at a lower temperature, but this necessitates a longer period. The solution of the
before mentioned substance or substances will however be accelerated by agitation.
If desirable I add to the compound thus resulting various other substances such
for example as arsenical or mercurial compounds or other poisonous ingredients to
render such compound more resistent to the detrimental attacks of the Terredo or of
other destructive Agency.
When such compound or compounds is or are applied to other purposes than for
protecting Ships it may not be requisite to add either of the before mentioned
poisonous compounds.
I have found that the compound or compounds resulting as before mentioned is
or are of great value in preventing the decay of wood and other perishable
substances, and will be found to possess great sanitary advantages.
The substances I prefer to employ in conjunction with carbolic acid or carbolic
acid and napthaline or creosote or other liquid hydrocarbon in carrying out my
Invention are gums, or gum resins, such as are soluble in Hydrocarbons or carbolic
acid such as copal, animi, Kauri, shellac, Resin, drying oils, or cotton-seed oil, or
castor oil, Bitumens Asphaltum paraffin camphor India rubber Gutta Percha and
other hard or soft gums except those soluble in water which are soluble in carbolic

page_text: acid or in a mixture-of Carbolic acid and Napthaline or creosote or other liquid
hydrocarbon.
I find in practice that good results may be obtained by employing about from
20 lbs of Carbolic acid with from about 20 lbs to 45 lbs of Gum Kauri or any of the
other substances hereinbefore mentioned which may be selected.
When I wish to employ the resulting, compounds for the purpose of coating or
sheathing iron or other vessels or submerged surfaces, I employ the same either
with or without the addition of from about 2 per cent. by weight to 5-per cent
by weight of any suitable arsenical or mercurial or other poisonous insoluble
compound.
When the product resulting as before mentioned is to be employed for the
purposes before mentioned I thin the compound when it is required to be more or
less fluid by employing Naptha Turpentine, Alcohol Benzole or oils whether
oxidized or not so as to render it more suitable and better capable of being
employed for coating metallic and other surfaces.
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 metallic or other
surfaces the said compounds being prepared by dissolving gums or substances of
the nature herein before defined in or with carbolic acid or in or with carbolic acid
in conjunction with Napthaline or creosote or both or other hydrocarbon liquid,
whether or not poisonous substances be used in addition thereto, and whether or
not the compound be thinned or diluted for use substantially as hereinbefore
described.
