I, WILLIAM PHILLIPS THOMPSON, F.C.S., M.I.M.E., of The Agency for
Foreign Patent Solicitors, 6, Lord Street, Liverpool, and 6, Bank Street,
Manchester, both in the County of Lancaster, and 323, High Holborn, in the
County of Middlesex, Civil Engineer, do hereby declare the nature of this
invention to be as follows:-
This invention has for its object an improvement on that kind of gum known as
gum tragasol, whereby its keeping qualities are improved and it is made more
suitable for sizing, especially for heavy loading without the aid of tallow, also for
manufacturing a pure vegetable gum either in the dry or liquid state.
The invention consists in obtaining an aqueous solution of that peculiar kind of
guin which is found in certain species of fucus algae and other seaweeds and which
is especially abundant in Caragheen moss (sphæroccus crispus), and adding this in
various proportions to ordinary gum tragasol made from the locust bean (ceratonia
siliqua). This seaweed gum mixed with gum tragasol appears to enable the latter
to be desiccated without decomposition, and accordingly the combined liquid can
he evaporated down to a solid and sold in this form, or can be sold in the liquid
form as gum.
It is not necessary to obtain the solution of the Caragheen moss in the liquid,
as other known methods of obtaining the principle of the Caragheen moss can be
employed and this principle added to the gum tragasol during manufacture or
after.

page_text: Civil Engineer, 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 :-
This invention has for its object an improvement on that kind of gum known as
gum tragasol, whereby its keeping qualities are improved and it is made more
suitable for sizing, especially for heavy loading without the aid of tallow, also for
manufacturing a pure vegetable gum either in the dry or liquid state.
The invention consists in obtaining an aqueous solution of that peculiar kind of
gum which is found in certain species of fucus alge and other seaweeds aud which
is especially abundant in Caragheen moss (sphaerococcus crispus), and adding this
in various proportions to ordinary gum tragasol made from the locust bean (ceratonia
siliqua). This seaweed gum mixed with gum tragasol appears to enable the latter
to be desiccated without decomposition, and accordingly the combined liquid can
be evaporated down to a solid and sold in this form, or can be sold in the liquid
form as gum. The proportions I prefer are from 5 to 15 per cent. of Caragheen
moss when the gum is not required to be evaporated to dryness, 25 to 50 per cent.
of Caragheen moss when making a solid gum the remaining percentage in the
hundred being gum tragasol.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, as communicated to
me by my correspondent, I declare that what I claim is :-
1. The improvement in the manufacture of gum or size for the purposes
described which consists in the combination of gum tragasol (the gummy matter
ceratonia siliqua) with the gummy atter found in Caragheen moss (sphaerococcus
crispus) or of other like algae fuci or kindred seaweeds.
2. The improvement in the treatment of gum tragasol whereby it can be
evaporated to the solid form without decomposition which consists in mixing it with
certain less easily decomposable gums more especially the gummy matter found in
Caragheen moss and evaporating the combined gums to dryness.
