PROVISIONAL SPECIFICATION.
A Portable Plant for Manufacturing Artificial Fuel.
I, ARTHUR JAMES STEVENS of Newport in the County of Monmouth Manager
of Works do hereby declare the nature of this invention to be as follows:-
The object of my said invention is to provide a convenient portable complete
plant for the manufacture of artificial fuel of such a capacity and nature as to
enable it to be attached to a suitable frame or support which may be mounted on
wheels or so arranged that wheels may be readily secured thereto or may have
convenient tackle for the purpose of hauling, raising, or lowering the whole for
transport, or the portable plant may be permanently built upon a railway or other
truck, wagon, or trolly so that the apparatus may be moved about from place to
place in order to work up small coal or the like into fuel when such material is
lying in heaps or otherwise collected at collieries, railway stations, or other depôts,
or on board vessels.
In carrying out my invention I provide a strong frame or skeleton body
preferably of timber and approximately of such a size as an ordinary railway
truck, or of such size as would enable it to be transported by such a truck or
arrangement of trucks or trollies, or the frame may have axles or supports for
wheels attached to it so that it may be mounted on such wheels and so transported
by road or across country where no railway or like lines are laid.
On the forepart or one end of the platform or frame I mount a pugmill of
convenient size and shape and under this is arranged the revolving die table on
which the blocks are compressed on the mixture issuing from the pugmill.
At the opposite end of the frame or platform or at a convenient point thereon I
secure a distributor or measurer with suitable hopper for regulating the proportion
of coal and pitch or other materials.
Between these two portions of the apparatus and extending under the distributor
I form a hopper projecting below the frame and hung and secured thereto by
strong framing or supports and carrying a pulley or drum round which revolves the
endless band of an elevator the opposite drum or pulley being pivotted above the
pugmill and so situated as to deliver the mixture raised by the elevator into
the same.
The materials are filled into the hopper of the distributor whence they fall into
the hopper or chamber below in which the elevator works and by this means
carried up to and into the pugmill whence the worked fuel passes into the moulds
of the revolving table and delivered in the shape of blocks in the usual way.
The parts of the apparatus are all suitably geared together so as to work at the
desired speeds and the whole may be actuated from the shaft of existing machinery
or a small engine and boiler or other motor may be carried by a second truck or
upon the same platform as the rest of the apparatus.

A Portable Plant for Manufacturing Artificial Fuel.
I ARTHUR JAMES STEVENS of Newport in the County of Monmouth Manager
of Works 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 a convenient and complete portable
plant for use in the manufacture of artificial fuel such plant being of a capacity and
nature enabling it to be attached to a suitable frame or support capable of being
mounted upon wheels for the purpose of transport either by road or by rail or upon
a platform or boat so that it might be water carried suitable tackle being employed
for raising, lowering &c. and provision made for attachment of the said tackle; or
the plant may be erected in first instance on a railway truck or trolly or trucks or
trollies or on a suitable boat or float so that the apparatus may be moved from
place to place in order to work up small coal or the like into fuel when such
material is lying in heaps or otherwise collected at collieries, railway stations or
other depôts or on board vessels.
For the purpose of more fully explaining the nature of my invention I have
caused to be attached to this Specification a sheet of drawings to which I shall
hereafter refer.
Figure 1 is a side elevation of my fuel plant and
Figure 2 is a plan of same.
In carrying out my invention I provide a strong frame or platform of timber or
metal A which may be part of a railway truck or road wagon or of a canal boat or
other vessel or may be capable of being lifted upon wheels or upon trucks or trollies
or vessels for transportation.
At one end of this frame or platform I erect a pugmill G of convenient size and
shape and under this is arranged the revolving die table H on which the blocks of
fuel are compressed when the mixture issues from the pugmill G.
At the opposite end of the platform or other convenient point I place a
distributor or measurer C with a suitable hopper or receptacle B for regulating the
proportion of coal, pitch or other material which is here introduced.
Below the main frame A and under the distributor and measurer C but between
it and the pugmill GI construct a second hopper or receptacle D in which on
suitable bearings revolves a pulley or drum E round which runs the endless band
of an elevator F the opposite drum or pulley H being mounted above the
pugmill G and so situated as to deliver the mixture raised by the elevator F into
the same.
The materials in the raw state are filled into the hopper B of the distributor or
measurer C whence they fall into the receptacle D and thence are elevated by
band F and its pockets up to and into pugmill G from which the worked up mass
is delivered into the moulds of die table H and when compressed in fuel press J are
delivered in blocks in the usual way.
The various parts of the machinery are geared together as follows:-
This gearing may be actuated from a shaft of any existing machinery at the
place where the plant is required to be used temporarily or a small engine and
boiler may be carried on the same or a separate truck or vessel.
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. In the manufacture of artificial fuel the use of a complete plant mounted on
a frame or platform capable of transport from place to place substantially as and
for the purposes described.

page_text: 2. For manufacturing artificial fuel the combination of a pugmill such as Ga
dietable and fuel press such as H an elevator and receptacle such as D and E and
distributor or measurer such as C with a railway truck or equivalent or a floating
vessel substantially as hereinbefore described and as illustrated by accompanying
drawings.
