PROVISIONAL SPECIFICATION.
Improved Method of and Apparatus for Mixing or otherwise Treating
Pulp and other Paper Makers' Materials.
We, JOHN ALMOND, Mill House, Bathford, Somerset, Mill Manager, and
STEPHEN FOX ANDREWS, Oldfield Park, Bath, Somerset, Managing Director, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in apparatus for mixing pulp & incor-
porating therewith, color, chemicals, or other foreign substances, also for the
reduction of paper or dry pulp, to a liquid or semi-liquid condition.
For this purpose we employ an archimedian screw of any suitable form,
mounted upon a revolving shaft; this apparatus being placed in a suitable vessel
containing the materials to be operated upon. In the case of mixing or reducing
pulp it will be sufficient to allow the said archimedian screw to revolve at any
suitable speed, in the midst of the materials contained in the before mentioned
vessel.
In cases where the operation, is one of mixing colors, chemicals, or other
foreign matter with the pulp, we introduce a pipe or pipes advantageously under-
neath the first coil of the said archimedian screw, & through this pipe or pipes,
the color or chemical passes to the pulp with which it is to be incorporated.
Dated this 21st day of November 1898.

Improved Method of and Apparatus for Mixing or otherwise Treating
Palp and other Paper Makers' Materials.
We, JOHN ALMOND, of Mill House, Bathford, Somerset, Mill Manager, and
STEPHEN FOX ANDREWS, Oldfield Park, Bath, Managing Director, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:
This invention relates to improvements in apparatus for mixing pulp, and
incorporating therewith, colour, chemicals, or other foreign substances; also
for the reduction of paper or dry pulp to a fluid or plastic condition.
For this purpose we employ an archimedian screw, either continuous or in
segments of any suitable form, mounted upon a revolving shaft, this apparatus

upon.
In the case of mixing or reducing pulp, it will be sufficient to allow the said
archimedian screw to revolve at any suitable speed, in the midst of the materials
contained in the before mentioned vessel.
In cases where the operation is one of incorporating colours, chemicals, or
other foreign matter with the said pulp, we introduce a pipe or pipes advan-
tageously underneath the first coil of the said screw, and through this pipe or
pipes, the colour or chemical passes to the pulp with which it is to be incorporated
and in order that our invention may be more readily understood and carried into
practice we have illustrated it in drawings Nos. I and II.
Figs. 1 and 2 on Sheet 1 show respectively a plan and sectional elevation of
our improved apparatus, arranged with a continuous screw A, supported on a
vertical shaft B, and driven from the pulley C, in any convenient manner. D) is
the tank which contains the pulp to be operated on, and in which the before-
mentioned screw A revolves.
Its operation is as follows; the tank D having been filled to any convenient
height, with the pulp to be operated on, the screw A is set in motion, the
direction of its rotation being either right or left as may be most convenient,
the pulp being thereby agitated in such a manner as to thoroughly mix with
and incorporate the colouring or other foreign matter.
The above operation is equally adepted for the reduction of paper or dry
pulp to a fluid or plastic condition.
Figs. 3 and 4 on Sheet 2 show respectively a plan and sectional elevation of
our improved apparatus, arranged with segmental screws in lieu of the continuous
screw, the same letters of reference apply, as also the foregoing description of
the operation.
What we claim is:-
The screw continuous or segmental working in a tank, the said tank containing
