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 MANU-
FACTURE OF ARTIFICIAL FUEL, to be as follows:
Our Invention consists in the application of two opposite cupped dies or pressing
plates, each fitted with ventilating holes, and fixed to opposite pressing rams
moving in horizontally or vertically, preferably the former, whereby all the sharp
edges or arridges of the Blocks are rounded or bevelled off, so as to reduce fracture
in handling.
The Invention will be readily understood by reference to the accompanying
drawing, in which Figure 1. represents the Machine in side Elevation, and
Figure 2. in plan.
A is the Bedplate of the machine on which are fitted two metal boxes D D
tooled out to fit the two pressing Rams E E; these Rams are made larger at the
ends G G, where the cupped plates are fastened to them, to suit the size and shape
of the Blocks to be pressed; B is the revolving mould plate, turning on the
shaft C; the cupped plates H H are dished all round, so that the outer edges may
enter the moulds before the body of the plates; and as these cupped plates enter
the mould from opposite sides, the effect is to round off or bevel all the sharp
corners or edges of the Blocks whilst being pressed-in the mould; each of these
cupped plates is provided with small ventilating holes, to allow the imprisoned
air to escape during pressure; these holes are shown at I I II. A sectional view
of the Block whilst in the mould is shown at M, showing the corners rounded of;
whilst N shows the finished block after pressure,

We, JOHN ARTHUR YEADON, of 4 Albion Place, Leeds, and ROBERT MIDDLETON,
of Sheepscar Foundry, Meanwood Road, Leeds, in the County of York, both
Engineers, do hereby declare the nature of our invention for IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR THE MANUFACTURE 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:-
Our Invention consists in the application of two or more opposite cupped dies
or pressing plates, each fitted with or without ventilating holes, and fixed to
opposite pressing rams, or minde solid with the rams and forming part of the same,
moving simultaneously or otherwise, and whereby, with the aid of similar corners
in the moulds, all the sharp edges or arridges of the Blocks, whatever the shape of
the Blocks, are rounded or bevelled off on all sides, so as to reduce fracture in
bandling and consequent percentage of loss occasioned in loading up, transit, and
shipment.
Our Invention will be readily understood by reference to the drawings filed
with our Provisional Specification in which Fig. 1 represents the Machine in Side
Elevation, and Fig. 2 in Plan.
A is the Bedplate of the Machine, on which are fitted two metal boxes D. D.
tooled out to fit the two pressing rams E. E; these Rams are made larger at the
ends G. G. where they are either cupped themselves, or the cupped plates are
fastened to them to suit the size and shape of block to be pressed; B is the
revolving mould plate turning on the shaft C; the corners of the moulds being
rounded or bevelled off as shown at O. O. or made circular if preferred, the cupped
rams or plates H. H. are dished all round, so that the outer edges may enter the
moulds before the body of the plates or rams, and as these enter the moulds from
opposite sides, the effect is to round off or bevel all the sharp corners or edges of
the Blocks on both sides whilst being pressed in the moulds, the curved corners of
the moulds doing the rest. Each of these cupped rams or plates is provided with
small ventilating holes if necessary, to allow the imprisoned air to escape during
pressure; these holes are shown at I. I. I. I. shown on the enlarged views of the
Ram end. A sectional view of the Block whilst in the mould is shown at M with
the edges and corners rounded off; whilst N shows a perspective view of a finished
Block after pressure.
We wish it to be thoroughly understood that we do not round or bevel off the
corners or edges of the Blocks either for ornament or ease of manufacture; but
with the object of avoiding fracture in handling and loading up, and for the
purpose of avoiding waste in transit or shipment.
2. W
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. The use of improved apparatus whereby the edges and corners of Blocks of
artificial fuel are, whilst being pressed, rounded or bevelled off, with the object

page_text: of avoiding fracture or crumbling in handling and loading up, and for the purpose
of avoiding waste in transit or shipment.
2. The use and arrangement of opposite cupped dies or rams; moving simul-
taneously or otherwise, substantially as described herein and shown on the
accompanying drawing with the object and for the purpose set forth.
3. In combination with the opposite cupped dies or rams, the use of moulds
having rounded or bevelled corners, or cylindrical if preferred, so as to leave all
and every side and corner of a Block rounded or bevelled off as shown at N., with
the object and for the purpose set forth.
4. The application of perforations in such cupped plates or rams; to allow the
escape of imprisoned air or vapour during pressure, thereby ensuring solidity and
putting a better face on the Blocks.
