page_text: Improvements in Machinery for the Manufacture of Compressed
Fuel from Coal.
I, SAMUEL BUTLER of 127 Bute Road Cardiff in the County of Glamorgan,
Engineer, 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 :-
This invention is designed to effect practical improvements in the arrangement
and construction of machines for utilizing "slack" or waste coal in the manu-
facture of compressed fuel known as "Patent Fuel." These improvements refer
more especially to that part of the machinery which heats and presses the coal.
In my improved machine I derive all the various motions required for the Pug,
Mill, Cooler, Feeding-pan Table and valve from one vertical shaft.
The lower end of this vertical shaft carries a beveled toothed wheel to which
rotary motion is imparted by a similar wheel fixed on the shaft of the Engine.
From this vertical shaft the motion is transmitted to the various parts of the
machinery in the manner hereinafter described.
Commencing from its lower end immediately at the end of the shaft is a cam
actuating a drawbar connected with the valve.
Next, above the bed of the press is a crank for imparting intermittent motion to
the moulding table by a rod connecting the crank with a pawl carried on a band
around the table.
Thirdly, above the crank is another cam actuating a drawbar connected with a
rocking shaft above the table, and forming the kicker gear.
Fourthly, above the upper cam is the feeding pan, and above the pan is the
cooler, and on the top of all the pug, all deriving their motion from the vertical
shaft.
The advantage of this form of construction is that pulleys and straps are entirely
avoided, and moreover, the materials find their way by gravity through the pug
into the cooler, thence into the Feeding-pan, thence into the moulds of the table.
where they are pressed by an inverted steam cylinder carried in the bed, and
having its piston-rod connected with the end of a lever, the other end being
pivoted on a fulcrum, carried by the ends of the thrust columns, which for this
purpose extend for the required distance below the bed.

page_text: The point of this lever to which pressure is applied is situated at about one
fifth of the total distance between the fulcrum and the steam cylinder. The
pressure is effected by means of a ram resting on the lever and projecting through
the bedplate.
In the accompanying drawings the same letters indicate the same parts
throughout.

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
1 claim is
1. The general arrangement and construction of a combined Fuel machine for
mixing, heating, cooling, feeding, moulding and pressing "Patent Fuel" in one
machine as herein described.
2. The method of pressing the fuel by means of an inverted Steam Cylinder
actuating a lever below the bedplate which lever drives a ram, as herein setforth.
