Year: 1862

page_text: LETTERS PATENT to Richard Archibald Brooman, of 166, Fleet Street,
in the City of London, Patent Agent, for the Invention of "IM-
PROVEMENTS IN MACHINERY FOR MOULDING AND COMPRESSING ARTIFICIAL
FUEL, PEAT, BRICKS, TILES, AND OTHER SUBSTANCES."-A communication
PROVISIONAL SPECIFICATION left by the said Richard Archibald
Brooman at the Office of the Commissioners of Patents, with his Petition,
on the 3rd November 1862.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said In-
vention for "IMPROVEMENTS IN MACHINERY FOR MOULDING AND COMPRESSING
ARTIFICIAL FUEL, PEAT, BRICKS, TILES, AND OTHER SUBSTANCES," (communicated
to me from abroad by Jean Baptiste Defrasne, of La Villette, Paris, France,)
to be as follows:-
This Invention consists in constructing and arranging moulding and pressing
machinery as hereafter described. Upon a bed I erect a pillar, for carrying
the axis of an oscillating beam; to this beam, in front of the pillar, two pistons
are connected, one at the end of the beam and the other near the pillar. One
piston is used to compress and mould the substances in moulds carried in a
revolving platform, and the other for driving the moulded or compressed

page_text: substances out from the moulds. Where the shape of the moulds will not
admit of the moulded articles being driven down through them, then I employ
a piston from below to force them up through the moulds; the latter piston is
made to move up and down by levers connected to the beam behind the pillar
through a connecting rod. The revolving platform carries several moulds, and
is made to revolve to present the articles first to the moulding piston and then
to the piston for driving out the moulded articles. Motion is communicated
to the outer edge of the platform, which is toothed for the purpose, through a
paul and lever worked from the same prime mover, which, through a con-
necting rod, drives the oscillating beam. The moulded articles are carried
away upon an endless belt.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent Office
on the 2nd May 1863.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of November, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Archibald Brooman, Her special licence that I, the said Richard
Archibald Brooman, my executors, administrators, and assigns, or such
others as I, the said Richard Archibald Brooman, my executors, adminis-
trators, and assigns, should at any time agree with, and no others, from
time to time and at all times thereafter during the term therein expressed,
should and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of Man,
an Invention for "IMPROVEMENTS IN MACHINERY FOR MOULDING AND COMPRESSING
ARTIFICIAL FUEL, PEAT, BRICKS, TILES, AND OTHER SUBSTANCES," (communicated
to me from abroad by Jean Baptiste Defrasne, of La Villette, Paris, France,)
upon the condition (amongst others) that I, the said Richard Archibald
Brooman, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly-describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent

page_text: Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said Richard Archibald Brooman, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement thereof, reference being had to the Drawings hereunto
annexed, that is to say:-
This Invention consists in constructing and arranging moulding and pressing
machinery as hereafter described. Upon a bed I erect a pillar for carrying
the axis of an oscillating beam; to this beam, in front of the pillar, two pistons
are connected, one at the end of the beam and the other near the pillar. One
piston is used to compress and mould the substances in moulds carried on a
revolving platform, and the other for driving the moulded or compressed
substances out from the moulds. Where the shape of the moulds will not
admit of the moulded articles being driven down through them, then I employ
piston from below to force them up through the moulds; this latter piston
is made to move up and down by levers connected to the beam behind the
pillar through a connecting rod. The revolving platform carries several
moulds, and is made to revolve to present the articles first to the moulding
piston and then to the piston for driving out the moulded articles. Motion is
communicated to the outer edge of the platform, which is toothed for the
purpose, through a paul and lever worked from the same prime mover, which,
through a connecting rod, drives the oscillating beam. The moulded articles
are carried away upon an endless belt.
a
Figure 1 of the accompanying Drawings is a longitudinal elevation, and
Figure 2 a plan, of a machine for moulding and compressing constructed
according to this Invention.
Upon a bed a I erect a pillar 6 for carrying the axis of an oscillating
beam d; to this beam, in front of the pillar b, two pistons f, f', are connected
by links g, h; the pistons f, f', work in guides e; the piston f is used to
compress and mould the substances in moulds, as hereafter described, and the
piston fto drive the compressed or moulded substances out from the moulds.
Beneath the guides e is a platform i revolving round its axis j; and carrying
the moulds z. Motion is communicated to the outer edge of the platform i,
which is toothed for the purpose, through a paul k and lever 1, worked by the
wheel m, which is fixed on the shaft n. I prefer that the number of teeth on
the outer edge of the platform i should correspond to the number of moulds
carried by the platform. To prevent the return of the platform a hooked
paul o, fixed to the pillar b, takes into the teeth on the platform i. Motion is

page_text: communicated to the machine by pulleys p, p², on the shaft q of the fly wheel.
The bent
The shaft also carries a pinion r, which gears into the wheel m.
9
shaft n, on which the wheel m is fixed, is connected to the oscillating beam d
by the connecting rod s.
The working of the machine is as follows:-The material to be moulded or
compressed having been placed in the moulds, the oscillating beam d in its
motion causes the piston f to plunge into the first mould, and compress the
material therein, which is thereby formed into a homogeneous mass. At each
moulding the platform i makes a partial revolution. When the platform has
completed half a revolution, the mould, the material in which was first com-
pressed or moulded, has come immediately below the piston f', which in
descending drives the compressed or moulded block out on to an endless belt t,
which conveys it away from the machine.
Where the shape of the moulds will not admit of the moulded articles being
driven down through them, I adopt the arrangement shown in dotted lines to
remove the articles from the moulds. In this arrangement the connecting
rod u imparts an oscillating movement to the lever x through the lever v; an
up-and-down motion is thus given to the piston y, which passes up through
the moulds as they successively become placed above it, and forces out the
moulded articles therefrom.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First, the construction and arrangement of machinery for moulding and
compressing, and for driving the moulded or compressed materials down
through the moulds, substantially as herein-before described and illustrated in
the accompanying Drawings.
Second, the arrangement for forcing the moulded or compressed materials
up through the moulds, substantially as herein-before described and illustrated
in dotted lines in the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this First day of May, One thousand
eight hundred and sixty-three.
