do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR HEATING AND MIXING THE MATERIALS EMPLOYED
to be as follows:-
IN THE MANUFACTURE OF ARTIFICIAL FUEL
دو
My improvements consist in the construction and employment of an apparatus
whereby the materials are first steamed and afterwards subjected to the action of
dry beat.
The apparatus consists of a vertical hopper or pug mill in which the materials are
placed and mixed by means of suitable agitators, steam being injected through ono
or more orifices. From this mill the materials pass over a "shoot" or inclined
plane into a horizontal cylinder having agitators mounted upon a shaft passing
through the axis of the cylinder the vanes or blades being placed at an angle to the
said shaft so as to screw or propel the materials forward through the cylinder.
During this process heated air is injected into the cylinder so as to expel all
moisture from the coal and other materials of which the fuel is composed, which
air and moisture passes off through a suitable outlet..
My Invention will be readily understood by reference to the accompanying
drawings, Figure 1 of which represents an elevation and Figure 2 a plan view of
the apparatus.
A is the steam pug mill consisting of a cylinder of wrought iron open at the top
and closed at the bottom with the exception of an opening or outlet, the size of
which can be regulated by the sliding door B.
C. Care jets for the admission of steam into the cylinder.
D is a shaft upon which are mounted agitators d for mixing the materials.
E is a cylinder of wrought or cast iron having an inlet at F and an outlet at G.
H is a shaft upon which are mounted agitators, the blades h of which are placed
at an angle so as to propel the material in the direction of the arrow.
J is a furnace for providing a continuous stream of hot air to the cylinder E, the
air entering at J₁ and passing out through the to the drying cylinder E.
By a careful regulation of the sliding door B a continuous discharge of the
mixture may be secured, which upon entering the drying cylinder E is driven
forward at the same rate of speed by the agitators h and upon leaving the cylinder
it is ready for moulding and pressing.

page_text: Ì SAMUEL BUTLER of 5 Chancery Lane, in the County of Middlesex do hereby
declare the nature of my Invention for "IMPROVEMENTS IN MACHINERY OR
APPARATUS FOR HEATING AND MIXING THE MATERIALS EMPLOYED IN THE MANU-
FACTURE OF ARTIFICIAL FUEL " and in what manner the same is to be performed
to be particularly described and ascertained in and by the following statement:-
This Invention consists in the combination of two processes known to manu-
facturers of artificial fuel as steam and dry heat, the mixture being first heated
with steam and afterwards with dry-heat as hereafter fully described.
The mixture to be heated is first passed into a steam Pugg, a suitably constructed
vessel having therein an agitator or a agitators where it is subjected to the fore-
named steam-process-by-injecting into it steam from one or more points.
This treatment completed, the mixture has hitherto been deemed sufficiently
prepared for moulding and pressing but the great quantity of moisture remaining in
it from condensation of steam renders the Fuel soft and porous and when damp
coal has to be encountered the amount of moisture from condensation of steam is
so excessive that the fuel is utterly useless and requires remaking.
My invention has particular reference to the extraction of this moisture of the
addition of a second process known as dry heat which I proceed to explain.
The first process having been completed the mixture is made to pass into a
heater, a suitably constructed vessel having therein an agitator or agitators by
which it is further mixed and tossed about. In this heater are provided an inlet
and outlet through which pass the hot fumes and gases from an adjacent furnace.
The dry heat thus obtained and applied acts directly upon the moisture itself
extracting every trace of the moisture before referred to which is carried away with
the waste products of combination to the stack.
This specification is accompanied with a sheet of drawings having two figures in
which similar letters refer to similar parts.
Fig 1. being elevation. Fig 2. the plan.
A is the steam pugg, a vertical Cylinder of wrought Iron or other suitable
material into which the mixture is received at the top and delivered at the bottom
through the slides B. 00¹ are steam jets by which steam is injected into the
mixture.
D. is a shaft having fastened upon it the agitators for mixing,
E. is the Heater, a horizontal cylinder of cast iron or other suitable material
closed at each end into which the mixture is admitted at F. and discharged at G.
H. is a shaft having upon it agitators which are so constructed with a slight
degree of screw as to drive the mixture forward to the outlet, this, making the
discharge continuous. I is the furnace for the supply of heat into the Heater
entering through the inlet J. and passing out at the outlet K.
By a careful regulation of the slide B. a continual discharge of the mixture may
be effected which on leaving the steam pugg A. enters the Heater E. at the point I
and being driven forward by every revolution of the agitators a likewise continual
discharge is procured at the point G. The mixture is then ready for moulding and
pressing.

page_text: Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The combination of steam pugg-mill A with the heater E. and furnace I.
substantially as herein shewn and described.
2. The construction and use of the heater E for the purpose of drying and
mixing the materials, substantially as herein shewn and described.
