Improvements in machinery for the Manufacture of Artificial Fuel
or other Similar Materials.
We, JOHN ARTHUR YEADON, of 4 Albion Place, Leeds, and ROBERT MIDDLETON of
Sheepscar Foundry, Meanwood Road, Leeds, both Engineers, do hereby declare the
nature of our invention for IMPROVEMENTS IN MACHINERY FOR THE MANUFACTURE OF
ARTIFICIAL FUEL OR OTHER SIMILAR MATERIALS to be as follows:-
A Combination of two Horizontal Cylinders or Mixing Troughs with open tops and
arched bridge, each fitted with internal shaft and adjustable knives or blades, the shafts
to be connected together with belt and cone pulleys, change wheels, or other suitable
connections as may be preferred, the object being to ensure a continuous mixture of
small coal and pitch, or other materials in different and suitable proportions as may be
desired.
Although we claim the use of our Invention in the manufacture of other materials in
addition to that of Artificial Fuel, it will perhaps make our description in this
Specification simpler and clearer if we describe its use for Coal and Pitch.
The Invention will be understood by referring to the accompanying Drawing, in
which Fig. 1 shows a side elevation of the machine, Fig. 2 an end elevation of the
same, whilst Fig. 3 shows a plan.of the upper and smaller cylinder, and Fig. 4 a plan
of the lower and larger cylinder.
A is a Horizontal cylinder with a circular bottom and an open top, having a plate at
each end with boss to carry the shaft E. Attached to this shaft is a number of
adjustable knives or blades which can be altered in their angle or pitch as may be
desired; G is an arched bridge of the same sweep underneath as the bottom of the
cylinder, and bolted to the cylinder just behind the feeding Hopper C. The upper
cylinder B is fitted up in the same manner as the cylinder A, only on a smaller scale.
The action of the Mixing machine is as follows:-the ground pitch is delivered
continuously into the Hopper D, whence it falls into the cylinder B. The speed of the
shaft L, which is regulated by the cone pulleys II from the shaft E, or other suitable
arrangement, and the angle at which the adjustable knives or blades are set, regulate
the speed and quantity of pitch passing along; whilst still further to regulate this, the
bridge H which, with the bottom of the cylinder forms a complete circle, preventing

page_text: more pitch than can pass through the area of that circle, further regulates the quantity
of materials required. The Pitch falls through the outlet J into the bottom cylinder A.
The Coal is also delivered continuously into the hopper C, and is carried forward by
the adjustable knives F, through the bridge G, where it meets with the pitch falling
from above, and the two materials coal and pitch are thus mixed together and carried
forward continuously by the adjustable knives to the outlet K. The mixing machine
is driven by shaft and gearing at M; whilst the cone pulleys I I and the angle at which
the adjustable knives are set in both cylinders, regulate the speed or proportion of the
materials passing through the cylinders; and the arched bridges still further regulate
the exact proportion or quantity.
We wish it to be understood that what we claim as our Invention consists in the use
and combination of the two cylinders fitted with arched bridge, with the shafts and
adjustable knives, and cone pulleys change wheels or other suitable connections.

We, JOHN ARTHUR YEADON, of 4 Albion Place, Leeds, in the County of York, and
ROBERT MIDDLETON, of Sheepscar Foundry, Meanwood Road, Leeds, in the County of
York, both Engineers do hereby declare the nature of this invention and in what
manner the same is to be perforined, to be particularly described and ascertained in
and by the following statement :-
A combination of two Horizontal Cylinders or Mixing Troughs with open tops and
arched bridge, each fitted with internal shaft and adjustable knives or blades, the shafts
to be connected together with belt and cone pulleys, change wheels, or other suitable
connections as may be preferred, the object being to ensure a continuous mixture of
small coal and pitch, or other materials in different and suitable proportions as may be
desired.
Although we claim the use of our Invention in the manufacture of other materials
in addition to that of Artificial Fuel, it will perhaps make our description in the
Specification simpler and clearer if we describe its use for Coal and Pitch.
The invention will be understood by referring to the drawing left with the
Provisional Specification, in which Fig. 1 shows a side elevation of the machine,
Fig. 2 an end elevation of the same, whilst Fig. 3 shows a plan of the upper and
smaller cylinder, and Fig. 4. a plan of the lower and larger cylinder.
A is a Horizontal cylinder with a circular bottom and an open top, having a plate at
each end with boss to carry the shaft E. Attached to this shaft is a number of
adjustable knives or blades which can be altered in their angle or pitch as may be
desired; G is an arched bridge of the same sweep underneath as the bottom of the
cylinder, and bolted to the cylinder just behind the feeding hopper C. The upper
cylinder B is fitted up in the same manner as the cylinder A, only on a smaller scale.
The action of the Mixing machine is as follows: the ground pitch is delivered
continuously into the Hopper D, whence it falls into the Cylinder B. The speed of the
shaft. L, which is regulated by the cone pulleys I, I, from the shaft E, or other suitable
arrangement, and the angle at which the adjustable knives or blades are set, regulate
the speed and quantity of pitch passing along; whilst still further to regulate this, the
bridge H which, with the bottom of the cylinder forms a complete circle, preventing
more pitch than can pass through the area of that circle, further regulates the quantity
of materials required. The pitch falls through the outlet J into the bottom cylinder A.
The Coal is also delivered continuously into the hopper C, and is carried forward by the
adjustable knives F, through the bridge G, where it meets with the pitch falling from
above, and the two materials coal and pitch are thus mixed together and carried forward
continuously by the adjustable knives to the outlet K. The Mixing machine is driven
by shaft and gearing at M; whilst the cone pulleys I, I, and the angle at which the
adjustable knives are set in both cylinders, and the arched bridge still further regulate
the exact proportion or quantity.
Each arch has an upper rib-not shown in Fig. 1-which reaches to the level of the
top edge of its cylinder and thus material is prevented from passing over it. The best

page_text: plan however is to make the lower and nearer side of the feeding hopper project into
the cylinder until it touches the arched bridge; for this purpose the bridge is placed
close up to this projecting side of the hopper. By this arrangement no material-
however full the hopper-
-can pass over the arcb, all must go under it.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed, we declare that what we claim is :-
1. In machinery for mixing materials for Artificial Fuel or for similar purposes the
use and combination of Cylinders or Troughs each fitted with an arched bridge for
measuring and regulating the passage of materials through the same substantially as
described herein and as shown on the drawing left with the Provisional Specification-
with the object & for the purpose set forth.
2. In machinery for mixing materials for Artificial Fuel or for similar purposes the
use and combination of a measuring bridge and a shaft carrying blades (adjustable or
fixed) for mixing and moving the material along-substantially as described herein and
as shown on the drawing left with the Provisional Specification-with the object & for
the purpose set forth.
3. In machinery for mixing materials for Artificial Fuel or for similar purposes the
use and combination of two or more cylinders or troughs fitted with arched bridges in
combination with shafts fitted with blades, adjustable or otherwise, which shafts are also
fitted with speed cones (or some equivalent) whereby any relative revolutions and
consequent proportional output may be arranged for each trough & any proportional
mixture produced, (a series of troughs each containing an ingredient may thus be
arranged) substantially as described herein and as shown on the drawing left with the
Provisional Specification.
