We WILLIAM KENT of Cobridge in the County of Stafford, Engineer and Iron-
founder and CHARLES COPE of Kidsgrove in the said County Engineer and
Ironfounder do hereby declare the nature of this invention to be as follows:-
This invention has reference to an arrangement of machinery or apparatus for
working or mixing plastic materials, such as potter's clay, which comprises a mixing
vessel that may conveniently be octagonal or plain, but oblong. Within it are
arranged two parallel shafts provided with radial arms. Each of these shafts passes
through a hole in the bottom of the mixing vessel and through a vertical pipe formed
with or fastened to the bottom of the mixing vessel and extending nearly to its top so
as to form an annular wall around the shaft. To the radial arms are attached frames
that extend downward nearly to the bottom of the mixing vessel and which carry
inclined plates or bars so arranged as to form what may be called louvre like grids
and to serve for raising and mixing together the solid and liquid contents of the
mixing vessel. The shafts may be driven by bevil gear or otherwise from above or
from below. Framnes with inclined mixing plates or bars, as described, may be
applied in mixing apparatus having one shaft only and which, in other respects, may
be of ordinary construction.

We, WILLIAM KENT, of Cobridge in the County of Stafford, Engineer and
Ironfounder and CHARLES COPE of Kidsgrove in the said County Engineer and
Ironfounder 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 reference to an arrangement of machinery or apparatus for
working or mixing plastic materials such as potter's clay which comprises a mixing
vessel that may conveniently be octagonal in plan.
Within it are arranged two parallel shafts provided with radial arms.
Each of these shafts passes through a hole in the bottom of the mixing vessel and
through a vertical pipe formed with or fastened to the bottom of the mixing vessel
and extending nearly to its top so as to form an annular wall around the shafts. To
the radial arms are attached frames that extend downward nearly to the bottom of the
mixing vessel and which carry inclined plates or blades so arranged as to form what
may be called louvre-like grids and to serve for raising and mixing together the solid
and liquid contents of the mixing vessel. The shafts may be driven by bevil gear or
otherwise from above or from below. Frames with inclined mixing plates or blades
as described may be applied in mixing apparatus having one shaft only and which in
other respects may be of ordinary construction.
In the accompanying drawings Fig. 1 is a longitudinal vertical section; Fig. 2 is a
transverse section and Fig. 3 à plan, with certain parts removed, of machinery or
apparatus according to this invention.
1 is a mixing vessel or chamber (of any suitable form in plan such as octagonal
form) carried by suitable supports. It is open at the top for the introduction of
materials to be worked or mixed and at its bottom is provided with two holes 2, 2,
through each of which passes a vertical shaft 3.
The shafts 3, 3 are parallel to each other and are driven from the horizontal driving
shaft 4, by bevel gearing 5, 5 as shewn. The lower ends of the shafts 3 are carried in
bearings 6, 6, which also serve as bearings for the driving shaft 4. The upper ends of
the shafts 3 work in bearings 7, 7, carried by a frame 8 secured to the top of the
mixing vessel 1. 9, 9 are pipes secured to the bottom of the vessel 1 above the
holes 2, 2.and extending upward nearly to the top of the vessel.
The shafts 3, 3 pass through these pipes each of which forms an annular wall to
the shaft that passes through it and serves to prevent material in the mixing vessel
working through the holes 2, 2. Each shaft 3 is provided with radial arms 10, 10
and to each such arm a frame 11 is attached which extends downward nearly to the

page_text: bottom of the mixing vessel. Each frame carries inclined blades or plates 12, 12,
forming louvre-like grids that serve to raise and mix the solid and liquid contents of
the mixing vessel when the shafts 3,3 are rotated.
Having now particularly described and ascertained the nature of the said invention
and in what manner it is to be performed we declare that what we claim in machinery
or apparatus for working or mixing plastic materials is :-
1. A pipe rising from the bottom of the mixing vessel and forming an annular wall
to a mixing shaft that passes through the bottom of the mixing vessel substantially as
described and for the purpose specified.
2. A frame connected to a rotating shaft and provided with inclined blades or plates
substantially as described and for the purpose set forth.
3. We also claim the improved machinery or apparatus for working or mixing
plastic material such as potter's clay constructed, arranged and operating substantially
as hereinbefore described with reference to the drawings annexed.
