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 a certain arrangement or com-
bination of levers whereby we obtain great rigidity and reduction of strain
during pressure on Blocks of Artificial Fuel whilst remaining in the Moulds of
the pressing Machine.
The Invention will be readily understood by reference to the accompanying
Drawing, Figure 1 of which represents front elevation, and Figure 2 the side
elevation of Machine..
A is a hollow bed plate of the box section; B is a girder circular at the top with
a flanged sole plate resting on and bolted down to brick work or ashlar and secured
to the bed plate.at CC; D D are upright levers, rocking on pins at E E at the
bottom, and connected at the top by tension bolts F F to the double crank G; this
crank is connected at the two points H H by pins and nuts to the pendulum
lever I, the bottom of which is connected by the pin J, and an adjustable
connecting rod K to the revolving internal wheel L. By this means an oscillating
motion is given to the double crank G; and by means of the two bolts or
pins H H, connecting to the pendulum lever I, any torsional strain on the shaft M
is relieved or altogether removed, and the shearing strain is divided between two
crank pins. instead of one as formerly, and thus any liability of fracture is greatly
reduced. The connecting rod K is fitted with steel springs N N to relieve any
extreme pressure which may be put on the blocks whilst in the moulds O O O O of
the revolving vertical mould plate P.

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 a certain arrangement or com-
bination of levers, whereby we obtain great rigidity and reduction of strain
during pressure on Blocks of Artificial Fuel, whilst remaining in the Moulds of
the pressing Machine.
Our Invention will be readily understood by reference to the accompanying
Drawing filed with our provisional Specification in which Fig. 1. represents the
front elevation, and Fig. 2. the side elevation of Machine.
A is a hollow bedplate of the box section; B is a girder, circular at the top with
a flanged sole pláte resting on and bolted down to brick, ashlar, or other foundation
and secured to the bed plate at C. C; D. D. are upright levers, rocking on pins
at E. E at the bottom, and connected at the top by tension bolts F. F. to the inner
double crank G, whose shaft M is carried at this end by the bearing M¹; this
double crank is connected at the two points H. H. by pins, or bolts and nuts, or
other suitable means to the overhung crank and pendulum lever, and thus spans
the bearing M¹; or it may be cast solid with and so form one piece with the
overhung lever I, arrangements being made to get it into position. The bottom of
this lever is connected by the pin J, and an adjustable connecting rod K to the
revolving internal wheel L. By this means, an oscillating motion is given to the
pendulum lever I, and double crank G; and by means of the two bolts or
pins H. H. the torsional strain on the shaft M is relieved or altogether removed,
and the shearing strain is divided between the two crank connections instead of
one as in former machines, and thus any liability of fracture is greatly reduced.
The connecting rod K is fitted with steel springs N. N. to relieve any extreme
pressure which may be put on the blocks whilst in the moulds 0. 0. 0. O. of the
revolving mould plate P.
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:-
0
1. The combination--whether, built up, or cast or made solid,-on a shaft M, of
an inner double crank G, spanning across a bearing M³, and coupling up, in two (or
more) places on opposite sides of the shaft, to the overhung crank and penduluin
lever I, substantially as described herein and as shown on the drawing, with the
object of reducing torsional or other strains, and for the purpose of avoiding
breakages in machines for making Blocks of Artificial Fuel.

page_text: 2. The arrangement of the above combination, in which the two inner crank
pins are prolonged through and into the overhung crank and pendulum lever, and
are thus made to act in the double capacity of crank pins and coupling up bolts in
a built up combination, substantially as described herein and as shown on the
drawing, with the object and for the purpose described.
3. The above combination in further combination with the yielding connecting
rod K, with the object of avoiding breakages in Machines for making Blocks of
Artificial Fuel,
JOHN ARTHUR YEADON.
