PROVISIONAL SPECIFICATION.
Improvements in Preparing Cutch for Sale and for Use.
I, JAMES RICHARDSON CARRUTHERS, of 70, King Street, Tradeston, in the
County of Glasgow, North Britain, Manufacturing Chemist, do hereby declare the
nature of this invention to be as follows, that is to say:-
My said invention has for its object to treat cutch in any of the forms in which
it is ordinarily imported by improved preparatory processes in a manner to render
it more convenient and otherwise advantageous for sale and for use.
In carrying out my invention I take the cutch in any of its ordinary forms and
first thoroughly dry it, a temperature of about 100 degrees Fahrenheit being
sufficient for the purpose. I next pulverise the cutch, which cannot be satisfactorily
done unless the cutch is almost completely free from moisture. As, however, the
powder is not quite suitable for purposes to which the cutch is applied I convert it
into a granular form, by treating it with steam, water, or other suitable liquid, and
subjecting it to the operation of mixing and drying apparatus. After the material
has been brought to a suitable granular condition, I, if necessary drive off more or
less of the moisture by means of heat. The resulting granular product whilst
similar in color to the original cutch, is in a condition to be easily and conveniently
handled and dissolved for use, and can be accurately measured in proper quantities
with facility.
Or I may first reduce the cutch to a paste with water or other suitable liquid,
and then, granulate it as hereinbefore described; or the paste may be made into
sheets, layers or cakes which after being sufficiently dried may be broken up,
separated into grains of various sizes by riddling.
Dated this Eleventh day of February 1896.

Improvements in Preparing Cutch for Sale and for Use.
I, JAMES RICHARDSON CARRUTHERS, of 70 King Street, Tradeston, in the
County of Glasgow, North Britain, Manufacturing Chemist, 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, that is
to say :-
My said invention has for its object to treat cutch, in any of the forms in which
it is ordinarily imported, by improved preparatory processes, in a manner to render
it more convenicut and otherwise advantageous for sale and for use.
In carrying out my invention I take the cutch in any of its ordinary forms, and
after separating non-pulverable matter, such as moisture, by subjecting it to the

page_text: action of hot or dry air, in a centrifugal machine, or otherwise, according to the
condition or quality of the cutch, I next reduce the mass to powder or small grains.
The powder I convert into granular material by treating it with steam, water, or
other suitable liquid and subjecting it to the operation of mixing and drying
apparatus. After the material has been brought to a suitable granular condition,
I may if necessary again subject it to the hot or dry air treatment.
The resulting granular product, whilst similar in color and appearance to the
original cutch, is in a condition to be more easily handled, is more easily dissolved
for use, and can be accurately measured in proper quantities with facility.
According to an other modification of my process I may first reduce the cutch to
a paste with water or other suitable liquid, and then dry it and granulate it as
hereinbefore described or the paste may be made into sheets, layers, or cakes,
which after being sufficiently dried, may be breken up and separated into grains of
various sizes by riddling.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
Preparing cutch for sale and for use by converting it into a granular product by
processes and operations substantially such as are hereinbefore described.
Dated this Sixth day of November 1896.
