page_text: LETTERS PATENT to Victor Adolphe Deaubeuf, of Maindy, Cardiff,
in the County of Glamorgan, for the Invention of "IMPROVEMENTS
IN MACHINERY OR APPARATUS FOR THE MANUFACTURE OF COMPRESSED OR
MOULDED FUEL PROM SMALL COAL AND OTHER MATERIAL"
Sealed the 16th June 1868, and dated the 23rd March 1868.
COMPLETE SPECIFICATION filed by the said Victor Adolphe Deaubeuf
at the Office of the Commissioners of Patents, with his Petition
and Declaration, on the 23rd March 1868, pursuant to the 9th
Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, VICTOR
ADOLPHE DEAUBEUF, of Maindy, Cardiff, in the County of Glamorgan,
send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS IN
MACHINERY OR APPARATUS FOR THE MANUFACTURE OF COMPRESSED OR MOULDED
FUEL FROM SMALL COAL AND OTHER MATERIAL," and have petitioned Her
Majesty to grant unto me, my executors, administrators, and assigns,
Her Royal Letters Patent for the same, and have made solemn
Declaration that I am the true and first Inventor thereof.

page_text: NOW KNOW YE, that I the said Victor Adolphe Deaubeuf, do hereby
declare that the following Complete Specification, under my hand and
seal, fully describes and ascertains the nature of the said Invention,
and in what manner the same is to be performed in and by the following
-statement:-
My Invention consists,―
Firstly. In the use of eccentrics to drive the mould plate, onc
eccentric pulling and the other pushing by means of notches, cach
corresponding to a mould, so that in this way the circular motion of
the mould plate may be equilibriated.
Secondly. In the construction and use of a peculiar shoot for the
purpose of filling the moulds, which shoot may be either partly or
completely covered or completely uncovered for the purposes horcin-
after explained.
Thirdly. In the peculiar construction of the feed press with its two
arms by which the material to be moulded is forced into the moulds,
these arms being so curved as to deliver or feed in a regular manner.
Fourthly. The substitution of cast-iron balls for bevil wheels for the
purpose of carrying the mould plates. The balls not being connected
together repair is facilitated, as in the event of the balls requiring to
be changed it is not necessary in order to do so to remove the mould
plate.
Fifthly. In the use of two cylinders for the purpose of compressing
the fuel.
My Invention consists further in various little portions of these
apparatus which will be best understood by reference to the complete
description now subjoined for the purpose of showing and, making
clearly to be understood the exact nature of my said Invention and
the means by which the same is effected.
In order to this I append to this Specification four Sheets of
Drawings, numbered I., II., III., and IV., having figures and letters of
reference marked thereupon, the like letter being used to denote a
similar or corresponding part in each Figure.
In these Drawings Figure 1 (Sheet No. I.) is a vertical view.
partly in section, and Figure 2 a plan of the distributor and an
endless chain of small wagons bringing the material to the mixing
apparatus.

page_text: Figure 3 (Sheet No. II.) is a front view of the press; Figure 4 is
a sectional view. of the mixing apparatus or pug mill and the feed
press.
.
Figure 5 (Sheet No. III.) is. a plan of the mixing apparatus, feed press,
and the gearing of the whole apparatus.
.
And Figure 6, Sheet No. IV., is a sectional view of the feed press,
its gearing, and the appliance for carrying off the blocks of fuel.
The materials to be mixed and pressed are brought to. the distributor K,
and placed, the coals into hopper K₁ and the pitch into K", and
thence they fall into one of the four divisions of the distributor.
These divisions are separated as shewn in Figures 1 and 2, and prevent
the pitch from mixing with the coals. Under this distributor, which
by means of its divisions regulates the necessary quantity to be delivered,
is carried an endless chain of small wagons which receives, raises, and
throws the materials into the mixing apparatus or pug mill, where they
are thouroughly mixed together or malaxated or kneaded by means of
the arms a.. For the purpose of softening the coal and melting the
pitch I admit steam into the pug mill during this process by means
of the cocks A¹, A", A; when the materials are sufficiently mixed
or kneaded together they are by means of the shoot B' sent into the
feed press B. (Sheets II. and III.). This shoot I make either partly
or wholly covered or wholly uncovered. In the Drawings (Sheets II.
and III.) it is shown completely uncovered for the purpose of cooling
the material before it passes into the feed press B.; more or less heat
may be retained if desired in the material by having the shoot partially
or wholly covered; from the shoot. the material or pug as it is now
termed, is sent into the feed press B where the arms B" force it to:
fill the moulds in a regular and uniform. manner. This system of
filling the mould admits of sufficient room being left round the press
to facilitate the execution of repairs should they be needed. The moulds
being filled the eccentrics H and I, which are connected by a strong
piece of india-rubber, are in contact with the notches N of the moveable.
plate C shown in Sheet No.. III. Figure 5. Eccentric H pulls on the notch
and I pushes it, and thus bring the mould f¹ under the fixed plate P. of
the framing of the cylinder and over the lever D'. At this period" of the
revolution of the mould plate the pistons D and E connected together
raise up the lever D', into which lever is fitted a hammer D which
striking on the plunger C₁ thereby compresses the pug contained in

page_text: the mould against the fixed plate P (Sheet No. IV, Figure 6).
Motion is given to the pistons D and E by means of the eccentric, E¹
the gearing E, and slide...valves E. The pistons are shewn, at the
end of their stroke, and the slide valves opened to let the steam escape
above the pistons through the exhaust pipes R, R'; during the time
compression is given to the block of fuel F" the catch G pushes off
the moulded block f" on to the rollers F. The steam having escaped
above the piston as herein-before just mentioned, the pistons descend
and the eccentrics H and I come into position to catch two notches
in the manner above described and compress another block and so
on continuously while the apparatus is in motion, the machine as
described and shewn being calculated to mould, press, and discharge ten
blocks for every revolution of the mould plate. In order to prevent
breakage of the bottom of the cylinders in which the pistons D.
and E are, the lever D' is so made at the part d near the piston rod
that it comes in contact in the descent of the piston, at or near the
end of the stroke of the same, with a block of wood which prevents
breakage. The mould plate turns upon irons balls C" round the circular
framing O which framing is hollow in the middle.
It will be seen that I make use of two cylinders for the compression
of the fuel, and that this is part of my Invention. These cylinders
are both connected when great strength is required, but one of them,
the cylinder D, can be employed singly by taking out the piston E
of the upper cylinder and disconnecting the gearing En. This is done
to make either larger or smaller blocks, and in order to vary the
size of the blocks I make use of plates of different sizes according to
the density required for the blocks. These plates are of course
moveable and may lay over the framing of the press where the moulds
are filled and under the plungers of the moulds.
Having now particularly described and ascertained the nature of my
said Invention, and the manner in which the same is to be performed,
I wish it to be distinctly understood that what I claim as of my
Invention and desire to secure by Letters Patent is,―
The general arrangement of machinery or apparatus as described
and illustrated in this Specification and appended Drawings.
Also the use of eccentrics for driving the mould plates as described
and illustrated.
The construction and use of the peculiar shoot for filling the moulds.

page_text: The peculiar construction of the feed press with its arms regulating
the delivery to the mould.
The substitution of cast-iron balls for bevil wheels for the purpose
of carrying the mould plates.
The use of two cylinders for compressing the fuel.
The use of lever D¹ with its cast-iron piece d with block of wood.
The use of rollers F on which the blocks are received on passing
from the moulds.
The use of the endless chain of small waggons.
In witness whercof, I, the said Victor Adolphe Deaubeuf, have
hereunto set my hand and seal, this Twentieth day of March,
in the year of our Lord One thousand eight hundred and sixty-
eight.
