I SAMUEL BUTLER, of N° 127 Bute Road, Cardiff, in the County of Glamorgan,
Engineer, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN APPARATUS FOR MIXING AND HEATING MATERIALS FOR THE MANUFACTURE OF
PATENT FUEL" to be as follows:-
This Invention relates to machinery or apparatus for the manufacture of
artificial fuel on the system wherein the two processes of "steam" and "dry heat"
are combined in order that the moisture left in the mixture of materials after
steaming may be thoroughly dried out.
+
And in order that my Invention may be more fully understood I herein give
reference to the accompanying drawings illustrative thereof.
Figure 1 represents a steam "pugg" or mixer into, which the material is
admitted at the top B and discharged at the bottom door C in the usual manner.
Under the common system the material would be pressed as soon as it passes out
of the door C, but according to my Invention I prefer to pass it through a drying
apparatus, one form of which is composed of a sheet iron cylinder E revolving very
slowly over the fire F, the heated gases from which find their way all round the
cylinder which may be caused to revolve by means of pinion and wheel G and H.
The mixture is fed to the cylinder at I by means of an archimidean screw D or
other equivalent and is caused to travel forward by the action of a series of blades
mounted on arins at an angle to the central shaft which act as a sort of screw
propeller and discharge the mixture at J. The blades also act as scrapers and
keep the interior of the cylinder free from the material which would otherwise
adhere to it.
Figure 2 represents another form of drying apparatus consisting of a cylinder of
fire-brick A built up of suitably shaped single bricks or segments. Near this is a
furnace B, the heated gases from which pass through a flue C running spirally
outside the cylinder as far as D where it communicates with the stack. In the
centre of the cylinder A is a shaft E having upon it a series of mixing arms for
agitating the material during its descent from the inlet F to the outlet G.

I, SAMUEL BUTLER, of 127 Bute Road, Cardiff, in the County of Glamorgan,
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 relates to machinery or apparatus for the manufacture of

And in order that my invention may be more fully understood I herein give

Figure 1 represents a steam "pugg" or mixer into which the material is

Under the common system the material would be pressed as soon as it passes out

The mixture is fed to the cylinder at I by means of archmedean screw D or other

The blades also act as scrapers and keep the interior of the cylinder free from

Figure 2 represents another form of drying apparatus consisting of a cylinder of
fire-brick A built up of suitably shaped single bricks or segments.
Near this is a furnace B the heated gases from which pass through a flue C
running spirally outside the cylinder as far as D where it communicates with the
stack. In the centre of the cylinder A is a shaft E having upon it a series of
mixing arms for agitating the material during its descent from the inlet F to the
outlet G.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed declare that what
I claim is:
First. The use of a surface of iron brick or other material kept hot by heated
gases for extracting moisture from Patent Fuel mixture after it has been subjected
to the heat of steam.
Second. The use of apparatus as described in reference to Figure 1 for drying
the Patent fuel mixture after it has passed through a process of heating by steam.
Third. The use of apparatus as described in Figure 2 for drying Patent fuel
mixture after it has passed through a process of heating by steam.
