Improvements in Discharging Motion Machinery or Apparatus for
the Manufacture of Artificial Fuel or other Plastic Materials.
We, JOHN ARTHUR YEADON, of 4 Albion Place Leeds, and ROBERT MIDDLETON,
of Sheepsear Foundry, Meanwood Road, Leeds, both Engineers, do hereby declare
the nature of our invention for IMPROVEMENTS IN DISCHARGING MOTION MACHINERY
OR APPARATUS FOR THE MANUFACTURE OF ARTIFICIAL FUEL OR OTHER PLASTIC
MATERIALS to be as follows :-
:-
:
Our present Invention bas 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 a double cam working in an open
ended Lever or Quadrant; which Lever swivels or rocks on a pin, and being con-
nected at the top by a Rod to a sliding Rain, gives an intermittent motion to the
same and by which motion, blocks of artificial fuel or other materials which have
previously been compressed in the moulds of a revolving table, are thrust out of the
mould, the pushing ram is withdrawn and remains stationary until the revolving
mould plate moves through another part of its revolution.
The Invention will be readily understood by reference to the accompanying
Drawings, in which Fig. 1 represents a side elevation, Fig. 2 a Plan, and Fig. 3 an
end elevation of the Machine.
A is the Bed plate of the Machine B is the revolving mould plate; C is the double
the
Cam, bolted to the split cam plate D which is keyed on the driving shaft E;
double cam works inside the open ended Lever F which rocks on the pin G, and is
connected at the top H, by the rod 1, to the sliding horizontal ram which pushes
out of the revolving mould plate B, on to the Plate K each block in rotation.
CL, CM, and CN are different views of the double cam itself, showing its shape and
the holes for bolting it to the Cam plate D.
The action of the Cam is as follows: whilst the revolving mould plate remains
stationary, one of the moulds containing a compressed block is opposite the pushing
out ram J; one half of the Caun pushes the Lever F upwards and forwards, by
י

page_text: which motion the block is quickly pushed out on the table K; as soon as the block is
clear of the mould, the other half of the Cam brings back the Ram J with a quick
return motion, and the shape of the two halves of the Cam is so designed as to leave
the Ram J stationary so soon as it has withdrawn from the mould on its return stroke,
until the mould plate has again moved forward in its rotation and brought the next
succeeding mould opposite the pushing out ram J, when the same motion is repeated.
The bolt is simply to act as a stay to strengthen the two ends of the Lever F.
We wish it to be understood that what we claim as our Invention consists in the
dwelling or stationary movement given to the Ram J, so soon as it has withdrawn
clear of the Mould plate B, by the use of the double Cam and the open ended
lever F; and the compulsory withdrawal of the Ram J at the proper moment, so as
to avoid any possibility of the ram remaining in the mould, and thus causing breakage
when the mould plate commences to rotate.

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 a double cam working in an open
ended Lever or Quadrant, which Lever swivels or rocks on a pin and being connected
at the top by a Rod to a sliding Ram, gives an intermittant motion to the same; and
by which notion blocks of artificial fuel or other materials which have previously been
compressed in the moulds of a revolving table, are thrust out of the mould, the pushing
ram is withdrawn and remains stationery until the revolving mould plate moves
through another part of its revolution.
The invention will be readily understood by reference to the drawings left with the
Provisional Specification in which Fig. 1 represents a side elevation, Fig. 2 a plan,
and Fig. 3 an end elevation of the machine.
A is the Bed plate of the machine; B is the revolving mould plate; C is the
double cam, bolted to the split cam plate D which is keyed on the driving shaft E;
the double cam works inside the open ended lever F which rocks on the pin G, and is
connected at the top H, by the rod I, to the sliding horizontal ram J which pushes
out of the revolving mould plate Bon to the plate K each block in rotation. CL, CM,
and CN are different views of the Double cam itself, showing its shape and the holes
for bolting it to the cam plate D.
The action of the cam is as follows whilst the revolving mould plate remains
stationery one of the moulds containing a compressed block is opposite the pushing
out ram Jone half of the cam pushes the lever upwards and forwards, by which
motion the block is quickly pushed out on the table K; as soon as the block is clear of
the mould the other half of the cam brings back the ram J with a quick return
motion, and the shape of the two halves of the cam is so designed as to leave the
ram J stationery, so soon as it has withdrawn from the mould on its return stroke,
until the mould plate has again moved forward in its rotation and brought the next
succeeding mould opposite the pushing out ram J, when the same motion is repeated.
The bolt is simply to act as a stay to strengthen the two ends of the lever F.
We wish it to be understood that our invention consists in the dwelling or stationery
movement given to the ram J, so soon as it has withdrawn clear of the mould plate B,
by the use of the double cam Cand the open ended lever F and the compulsory

page_text: withdrawal of the Ram J at the proper moment, so as to avoid any possibility of the
ram remaining in the mould, and thus causing breakage when the mould plate
commences to rotate.

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 or apparatus for the manufacture of Artificial Fuel or other material;
a Double cam (or its equivalent) with its projections suitably arranged, side by side,
in combination with and actuating an Open Ended Lever (or its equivalent) specially
arranged as to its open ends so that whilst one part of the cam acts on one end or
member the other half of the cam revolves freely, & whilst the latter half acts on
the other end of the open ended lever the former part of the cam revolves freely;
with the object of actuating in the positive & special manner described, the Pushing-
out Ram, substantially as described herein and as shown on the drawing left with the
Provisional Specification.
