in the City of London, E.C., Editor of the Mechanics' Magazine and
Patent Agent, for the Invention of "IMPROVEMENTS IN MACHINERY FOR
SOLIDIFYING, PRESSING, AND MOULDING."-A communication from abroad
by Felix Dehaynin, residing at Paris.
Sealed the 4th November 1859, and dated the 12th May 1859.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on
the 12th May 1859.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, E.C., Editor of the Mechanics' Magazine and Patent Agent, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MACHINERY FOR SOLIDIFYING, PRESSING, AND MOULDING," (communicated to me
from abroad by Felix Dehaynin, residing at Paris,) to be as follows:-
The present Invention relates to-improvements in machinery for solidifying,
pressing, and moulding, for which Letters Patent were granted to me the
14th April 1857, No. 1053. In the Specification of the said Letters Patent,
the materials after being mixed as therein set forth, were supplied to moulding

page_text: cylinders placed horizontally, and arranged round and upon a circular bed;
the materials were moulded by being pressed into and through the moulding
cylinders by means of plungers, the plungers being connected by links to a
collar, to-and-fro motions were imparted to the plungers through a collar driven
by an excentric upon a vertical driving shaft.
The present improvements consist in driving the plungers forward directly
by means of an eccentric, which subsequently draws them back again. The
plunger rods are formed with tails or projections, which enter and are guided
by grooves in a plate round the central shaft. This plate is cut away at
intervals, to allow of the parts most subjected to friction being lubricated.
The improvements further consist in transmitting from one vertical shaft
the principal motion to the whole apparatus, in driving this vertical shaft
directly from steam or other engines working horizontally, and in the general
arrangement of the parts of the apparatus. The shaft has its bearings upon
two or more friction rollers, and motion is communicated from one of these
rollers through a shaft and bevil gear to the platform or turn-table on which
the moulded articles are received. The greater part of the apparatus is
surrounded and supported by a cylinder or casing composed of flanged rings
bolted together. Connecting links in the compressing machine, as also driving
straps and belts in the whole apparatus, are dispensed_with.
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 12th November 1859.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, E.C., 2
Editor of the Mechanics' Magazine and Patent Agent, send greeting.

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

page_text: of Great Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR SOLIDIFYING, PRESSING, AND MOULDING,"
(a communication from abroad by Felix Dehaynin, residing at Paris,) 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 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 :-
The present Invention relates to improvements in machinery for solidifying,
pressing, and moulding, for which Letters Patent were granted to me the
14th April 1857, No. 1053. In the Specification of the said Letters Patent
the materials after being mixed as therein set forth, were supplied to moulding
cylinders placed horizontally, and arranged round and upon a circular bed;
the materials were moulded by being pressed into and through the moulding
cylinders by means of plungers, the plungers being connected by links to a
collar; to-and-fro motions were imparted to the plungers through a collar
driven by an excentric upon a vertical driving shaft.
The present improvements consist in driving the plungers forward directly
by means of an excentric, which subsequently draws them back again. The
plunger rods are formed with tails or projections, which enter and are guided
by grooves in a plate round the central shaft. This plate is cut away at
intervals to allow of the parts most subjected to friction being lubricated.
The improvements further consist in transmitting from one vertical shaft
the principal motions to the whole apparatus, in driving this vertical shaft
directly from steam or other engines working horizontally, and in the general
arrangement of the parts of the apparatus. The shaft has its bearings upon
two or more friction rollers, and motion is communicated from one of these
rollers through a shaft and bevil gear to the platform or turn-table on which
the moulded articles are received. The greater part of the apparatus is
surrounded and supported by a cylinder or casing composed of flanged rings
bolted together. Connecting links in the compressing machine, as also driving
straps and belts in the whole apparatus, are dispensed with.

page_text: Figure 1 of the accompanying Drawings is a vertical section of a machine
complete for solidifying, pressing, and moulding, constructed according to this
Invention; Figure 2 is a horizontal section taken above the trough support;
and Figure 2 is a horizontal section, taken on a level with the eccentric that
works all the rods of the moulding pistons.
A is the vertical shaft, which carries at its lower part two cranks b¹, b', coupled
together at right angles to one another, in order to receive simultaneously the
action of two horizontal steam engines X, X¹; c is an eccentric placed above
he cranks b, b', and which imparts the necessary motion to the slide valves of
the engines; d is a cross bar attached to the shaft A, and furnished at its
centre with a conical journal e. The shaft A is made eccentric at A', in order
to pass through the nave of the eccentric G, which imparts motion to the
moulding pistons E. Above the eccentric part A¹ of the shaft A, the same
shaft is made smaller, or it has a shaft A" of less diameter attached to it,
which carries at one part arms or branches f of an agitator or stirrer g, and
above this a mitre wheel h, which drives through the wheels i,j, and k, the
raising or endless chain l. The shaft A is supported by a plate o, which rests
upon a roller or several rollers m, m³, attached to the ends of the horizontal
shafts n, n'. The friction of the plate o on the roller m regulates the rotation
of the shaft n, which itself becomes a shaft for the transmission of motion; for
this purpose it has a bevil wheel p keyed to one end, which gears into a
pinion q mounted on a vertical shaft r. This shaft r carries a pinion s, which
gears into and drives a wheel t placed at one extremity of a shaft u. The
wheel t gears into a circular rack arranged round the distributing platform L,
in order to communicate to this platform a rotary motion. The shaft u carries
a pinion at the opposite end to that at which the wheel t is placed, which
pinion v gears into a rack formed round the movable platform y. Thus the
whole of the parts which form this machine are driven from one common
vertical shaft A, which itself receives motion from two horizontal steam
engines coupled together. The troughs M, which form a support and envelope
for the whole machine, is formed of several flanged parts, which are firmly
bolted together. Openings are formed to facilitate admission to its interior,
and to afford light in order to effect repairs, and to lubricate the parts
easily.
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 arrangement and construction of machinery for solidifying,
pressing, and moulding, herein-before described and illustrated in the accom-
Danving Drawings.

page_text: Second, the method of transmitting from one vertical shaft the necessary
motions to all the parts of the apparatus, such shaft being driven directly from
steam or other engines working horizontally, all as herein-before described and
illustrated in the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Twelfth day of November, One
thousand eight hundred and fifty-nine.
R. A. BROOMAN. (L.S.)
