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:-
Our present Invention has reference to the same Machine for which we applied for
Protection, on October 30th 1885, for two improvements numbered 13064 and 13067
respectively, and consists in the application of the Combination of a Vertical Pugmill
or Heating Cylinder fitted with internal shaft and adjustable knives, in which the
materials are heated to the required temperature; with a machine which also includes
a pugmill from which these materials are filled into moulds in a revolving mould plate
and made into blocks, which blocks are then powerfully compressed from both sides
simultaneously, thus forming one self-contained Machine in which the Materials can be
Heated, Moulded, and Compressed from both sides simultaneously.
The Invention will be readily understood by reference to the accompanying
Drawing, in which Fig. 1 represents a Plan, Fig. 2. the side Elevation, and Fig. 3 the
end elevation of the Machine.
A is the Vertical Pugmill fitted with internal shaft, adjustable knives, and inlet
pipes, in which the materials are heated to the proper temperature; this Pugmill is
supported by two girders B B which are fixed to the two sides C C, which rest on and
are bolted to the Bed or Frame D. The Heated materials escape through a door E at
the bottom of the Pugmill, and thence fall down the connecting spout H into the
smaller Pugmill F, at the bottom of which there is a motion for charging or pressing
the materials into the moulds of the revolving mould plate G, in which the moulded
blocks afterwards receive a powerful compression from both sides at the same time;
the whole forming one Self-contained Machine, by which combination the materials may
be heated, moulded, and compressed from both sides simultaneously.
What we claim, and what we wish it to be understood as our Invention is the
Combination of a Vertical Pugmill or Heating Cylinder, with a Machine in which the
Materials are Moulded, and compressed from both sides simultaneously.

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 performed, to be particularly described and ascertained
in and by the following statement :-
Our present invention has reference to the same machine for which we applied for
protection, on October 30th 1885, for two improvements numbered 13064 and 13067
respectively, and consists in the application of the Combination of a Vertical Pugmill
or Heating Cylinder fitted with internal shaft and adjustable knives, in which the
materials are heated to the required temperature; with a Machine which also includes
a pugmill from which these materials are filled into moulds in a revolving mould plate
and made into blocks, which blocks are then powerfully compressed from both sides
simultaneously, thus forming one self-contained machine in which the materials can be
Heated, Moulded, and Compressed from both sides simultaneously.
The invention will be readily understood by reference to the drawing left with the
Provisional Specification in which Fig. 1 represents a Plan, Fig. 2 the side Elevation,
and Fig. 3 the End Elevation of the Machine.
A is the Vertical Pugmill fitted with internal shaft, adjustable knives, and inlet
pipes, in which the materials are heated to the proper temperature, the Pugmill is
supported by two girders B, B, which are fixed to the two sides C, C, which rest on and
are bolted to the Bed or Frame D. The Heated Materials escape through a door E at
the bottom of the Pugmill, and thence fall down the connecting spout H into the
smaller Pugmill F, at the bottom of which there is a motion for charging or pressing
the materials into the moulds of the revolving mould plate G, in which the moulded
blocks afterwards receive a powerful compression from both sides at the same time;
the whole forming one self-contained Machine, by which combination the materials
may be heated, moulded, and compressed from both sides simultaneously.
The principal advantages of this combination will be understood from the following
description
-
The materials work down through the Vertical Heater A, by gravity, and therefore
do not require or or receive any forcing-down action from the revolving knives; they
further gravitate forward, when permitted, through the door E, into the pugmill or
charging box F. Hence, the flow of the materials forwards is specially easy to
regulate to the exact quantity required by adjusting the door E. This door being
close at hand is well within range of the attendant's eyes, & its manipulation is both
easy and reliable. The result of any adjustment also soon shows itself.
When it is required to momentarily stop the machine in the middle of its work, the
knives of the Vertical Heater and the Pugmill (which are by preference driven
independently) may be allowed to continue running; all that is required is the
closing of the door E; and immediately the door is again opened the materials flow

page_text: forwards as before. If a forcing-forward motion be given to the materials by the
knives, choking must follow-This, our arrangement avoids, the forcing-forward
motion being gravity.
The weight of the heater and its mountings tend to steady the rest of the machine
and to absorb any vibration in working.
All standing on one foundation makes the various parts of this self-contained
machine easier to erect, and keep in true relative order.
The Vertical Heater and its hopper (which latter is not shown on the drawing) may
be of any size and may conjointly contain a considerable quantity or store of material;
on the contrary the Charging box F is small and only holds a limited quantity
Hence when the door is closed the materials in the latter may be quickly worked off
into and through the adjacent Mould-plate, and any examinations or adjustment of the
various motions may then be clearly seen to and rapidly made. The whole is after-
wards started as easily as it was stopped, and the materials in the Heater, which are in
the same condition as if no stoppage had taken place, readily commence to flow
forward again.
This combination can be set to work itself clear of any materials left therein, and it
will do this, and leave itself clean and in good condition for another start.
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 :-
In a machine for the manufacture of Artificial Fuel or other similar materials, the
arrangement and combination of the parts of the Machine by which the materials are
treated, commencing from its entering into the Vertical Pugmill which discharges its
contents by gravitation through an adjustable door into the lower pugmill or Charging
box, from which the materials are charged forward into the adjacent Mould-plate,
wherein they afterwards receive compression from both sides simultaneously, sub-
stantially as described herein, and as shown on the drawing left with the Provisional
Specification, with the object and for the purpose set forth.
