I, GEORGE SPENCER, of 6, Cannon Street West, London, Civil Engineer, do
hereby declare the nature of the said Invention for "IMPROVED SOLUTIONS TO
BE USED IN THE MANUFACTURE OF PAINTS AND THE PRESERVATION OF WOOD, STONE,
AND METALLIC SURFACES, AND IN THE PRESERVATION AND WATERPROOFING OF
FIBROUS MATERIALS GENERALLY," to be as follows:-
I take benzole, eupion, or any of the refined oils or hydrocarbons and
naphthas obtained from petroleum, bitumen, wood, or coal, and substances similar
to coal, as also alcohol and similar spirits, and dissolve therein as much of
resin, or of the cheaper kinds of lacs or gums as may be required, firstly, to
form a vehicle or medium to serve as a substitute for the linseed and other oils
and turpentine hitherto used to receive and mix with the various colouring
matters used as paints, and when such colouring matters are thoroughly mixed
with the resinous solution above mentioned they can be readily used in the
ordinary manner for all kinds of painter's work, and, if required, a final coat
of the solution can be added as a varnish. I do not intend to exclude the use
of linseed or other oils in the manufacture of paints, as in some cases it
will be found advantageous to use a small proportion of such in combination
with the solution; but the object of my Invention is to lessen the need of

page_text: these expensive oils. Secondly, I use the hydrocarbon resin solution, either
alone or in combination with.a hydrocarbon solution of india-rubber or gutta
percha, for the preservation of wood, stone, and fibrous material, which sub-
stances can either be coated with the solution, or have it soaked into or forced
into their substance by any of the well-known means already in use; and in
the case of metallic surfaces each of the solutions or both combined may be
used at pleasure. Also in waterproofing fibrous fabrics the articles may be
coated or saturated with each solution separately or in combination with each
other, and the same remark applies to paints generally, which may be mixed
with either or both solutions, or laid on in alternate coats of each solution. As
it will in some cases be either cheaper or advisable to use wax, paraffin, tallow,
and other similar fatty matters (previously dissolved in benzole) in lieu of oils
for mixing with the foregoing solutions, I intend to use them accordingly,
when required to give extra polish or elasticity to the paints, or to the fabrics
which are to be preserved or waterproofed. In the manufacture of these solu-
tions I prefer to allow the spirit to take up as much of the solid matter as it
will dissolve, and afterwards thin down with additional spirit when required.
When canvas or such like material is saturated with one or both of the
solutions it can be readily manufactured into hose pipes or bands for driving
machinery, or the hose or band may be first made and then saturated with
the solution by means of pressure and heat, and I may mention that the
solution tends to give additional strength to the fibre.
Having now described my Invention, and the purposes to which it is
intended to apply, I wish it to be understood that what I claim as my
Invention, is,
Firstly, the hydrocarbon resin solution.
And, secondly, the hydrocarbon resin and caoutchouc or gutta percha
solution, with their combinations between themselves and the oils and fatty
matters, when used for the purposes and prepared in the manner set forth
herein.
