PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for Mixing
Fuller's Earth.
1, TOM LEE, of Brooklyn Mill, Ravensthorpe, near Dewsbury, in the County of
York, Yarn Dyer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide means for mechanically mixing fullers
earth, which is also applicable for determining the quantity of the said material
used, and which also acts as a detector of the presence of sand, grit, and the like
substances in the material.
•
In carrying out my said object I provide a machine or apparatus which consists
of a vessel or tub having a vertical shaft fixed therein which works on a bearing or
step at its lower end and is secured at its top end by means of a bracket upon a
suitable frame-work upon the top of the vessel or tub. The top of the, vertical
shaft carries a bevel wheel which gears with another bevel wheel upon a
horizontal shaft mounted upon the said framework and which is driven by pulley
and belt.
The vertical shaft is provided with one or more agitators composed of iuclined
blades.
The action of the machine causes the grit or foreign matter to be separated from
the fullers earth, the grit or foreign material gathering about the lower end of the
vertical shaft and the pure fullers earth around the bottom of the tub, so that if,
say 30 lbs. of fullers earth are put into the tub and 2 lbs. of grit or foreign matter
are deposited about the lower end of the vertical shaft, 28 lbs. of fullers carth
pure
will remain, thus the quantity of the material used can be determined.

COMPLETE SPECIFICATION.
Improvements in the Method of and Apparatus for Mixing
Fuller's Earth.
I, Tom Lee, of Brooklyn Mill, Ravensthorpe, near Dewsbury, in the County of
York, Yarn Dyer, 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 :-
The object of my invention is to provide means for mechanically mixing fullers
earth, which is also applicable for determining the quantity of the said material
used, and which also acts as a detector of the presence of sand, grit, and the like
substances in the material.

page_text: In carrying out my said object I provide a machine or apparatus which consists
of a vessel or tub A, having a vertical shaft B fixed therein, which works on
a bearing or step C at its lower end, and is secured at its top end by means of a
bracket D upon a suitable frame work E, upon the top of the vessel or tub A.
The top of the vertical shaft B carries a bevel wheel F which gears with another
bevel wheel G upon a horizontal shaft H mounted by pedestals J and K upon the
said frame work E, and which is driven by fast pulley L, and belt. N is the loose
pulley. O and P are loose collars secured by setscrews upon the horizontal
shaft H. The collar O is to prevent the horizontal shaft sliding in its bearings, the
collar P is to keep the loose pulley in position on the horizontal shaft H.
The vertical shaft is provided with one or more agitators composed of inclined
blades O fastened, by boss R and setscrew S, upon the shaft B.
The action of the machine causes the grit or foreign matter to be separated from
the fullers earth, the grit or foreign material gathering about the lower end of the
vertical shaft, and the pure fullers earth is held in suspension, so that, if say 30 lbs.
of fullers earth are put into the tub, and 2 lbs. of grit or foreign matter are
deposited about the lower end of the vertical shaft, 28 lbs. of pure fullers earth will
remain, thus the quantity of the material used can be determined.
The means for changing the driving belt from one pulley to the other is as
ordinary. T indicates the guide or fork, U the rod, and Y the lever.
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 :
1. A method of mixing fullers earth in which the said material is mechanically
stirred or mixed by agitators actuated by mechanism, in the manner substantially
as set forth.
2. A machine for mixing fullers earth in which the said material is mechanically
stirred or mixed by agitators actuated from a vertical shaft deriving its rotation,
substantially as shown and described.
3. In machinery or apparatus for mixing fullers earth, the combination of a
vessel or tub A, vertical shaft B, bearing or step C, bracket D, frame work E,
wheels F and G, horizontal shaft H, pedestals and K, and fast pulley N, for
actuating agitators carried upon the said vertical shaft, such as shown and
described.
