page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SIMEON
BROADMEADOW, of the Town of Abergavenny, in the County of Monmouth,
Civil Engineer, send greeting.
WHEREAS His present most Excellent Majesty King George the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date
at Westminster, the Second day of April, in the sixth year of His reign,
did, for Himself, His heirs and successors, give and grant unto me, the said
Simeon Broadmeadow, His especial licence that I, the said Simeon Broad-
meadow, my exors, admors, and assigns, or such others as I, the said Simeon
Broadmeadow, my exors, admors, and assigns, should at any time agree with,
and no others, from time to time and at all times during the term of
Fears therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my
Invention of "An APPARATUS FOR EXHAUSTING, CONDENSING, OR PROPELLING
AIR, SMOKE, GAS, OR OTHER AIRIFORM PRODUCTS;" in which said Letters Patent
there is contained a proviso obliging me, the said Simeon Broadmeadow, by
an instrument in writing under my hand and seal, particularly to describe.
and ascertain the nature of my said Invention, and in what manner. the
same is to be performed, and cause the same to be inrolled in His Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said in part recited Letters Patent, as in and by the
same, reference being thereunto had, will more fully and at large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, 1, the said
Simeon Broadmeadow, do hereby declare that the nature of my said Inven-
tion herein-after described does not in any way whatsoever interfere with a
Patent already granted to me, bearing date 19 January 1824, but that the
manner in which the present Invention is to be performed is particularly!
described and ascertained as follows (that is to say) :-
In the Drawings hereto annexed are represented various views and sections
of my Apparatus for Exhausting, Condensing, or Propelling Air, Smoko, Gas,
or other Airiform Products as aforesaid, reference being thereto bad, and to
the figures and letters marked thercon, as follows (that is to say):-
My Invention consists in a particular arrangement of machinism hereafter to
be described, for the purpose of exhausting or withdrawing the air, smoke, gas,
or other airiform products generated either in the process of distillation, and
thereby withdrawing the pressure from the interior of the apparatus to any
flue or chimney connected with the furnace or fireplace, thereby producing the
necessary draft or current of air requisite to the combustion of the fuel, and
at the same time propelling the same, after it has been converted to smoke or
other elastic fluid, either through flues under ground or in any way disposing
of the same as may be found most convenient. This action is performed by
one or more inverted vessels working in water or any other suitable liquid,
according to the gas, air, or smoke to be operated on, which will be more
fully described and ascertained by reference to the Drawing hereto annexed.
Fig. 1 represents a sectional elevation of an apparatus where two inverted
vessels are acted on by the alternate motion of a lever from which they are
suspended at equal distances from the fulcrum thereof. a, a, is the lever
from which the vessels are suspended which moves on the fulcrum at a', and
has an alternating motion imparted to it by a steam engine or other adequate
first mover. b, b, b, b, and c, c, c, c, are the two inverted vessels before men-
tioned, which are perfectly air-tight, except being open at the lower extremity.
d, d, d, d, and e, e, e, e, are the larger vessels or tanks filled to the line f, f,
with water or other liquid, in which the inverted vessels b, b, b, b, and c, c, c, c,
respectively ascend and descend by the action imparted from the lever a, a, as
before described. g, h, i, is a tube or pipe passing through the bottom or
other convenient part of the vessels d, d, d d, and e, c, e, e, and reaching
above the surface of the water line f. f. At the extremities g and i aro
placed valves opening respectively towards the interior of the vessels b, b, b, b,
and c, c, c, c, and at h connected with the flue or furnace, where the action or
operation of exhausting is purposed to be applied. k, l, and m, n, are separate

page_text: pipes passing through the bottom or other part of the vessels d, d, d, d, and
e, e, e, e, and also reaching a little above the surface or water line at f, f.
These pipes or tubes open or lead into the larger tube or trunk o, o, o, o, and
have valves placed at the extremities and n, opening towards the interior
of the trunk or tube o, o, o, o, which is led in the most convenient direction
as circumstances may require. To put this arrangement of my apparatus in
action it is requisite to impart motion to the lever a, a, as before described,
which, raising and depressing the inverted vessels b, b, b, b, and c, c, c, c, the
nir, smoke, gas, or other airiform products are drawn or exhausted during the
ascent through the tube g, h; i, from the furnace, and on the alternate descent
of each inverted vessel propelled or driven forward through the tubes k, l, and
m, n, into the trunk o, o, o, o, the valves at 9 and i opening during the ascent
of the inverted vessels aforesaid and closing during the descent, and the exit
or outlet valves at 7 and m opening during the descent of the inverted vessels
aforesaid and closing during their ascent respectively, thereby causing a
regular draft or exhaustion to take place at the point h, and a continuous
blast or current of air or other elastic fluid to flow from and into the trunk
0, 0, 0, 0.
Fig. 2 represents a sectional elevation of an arrangement of my apparatus
for exhausting or propelling air, smoke, gas, or other airiform products, which
I recommend in situations where power is not available as a first mover, or
where the process is of a slow and regular nature. It consists in suspending
an inverted vessel by a chain or rope, either passing over pullies or connected
with a lever, so that a counterbalance or weight, rather exceeding the weight
of the vessel, may at all times during the operation of exhaustion act as a
power to raise the inverted vessel, and produce the effect as before described.
a, a, a, a, is the inverted vessel. b, b, b, b, is the tank containing water or
other liquid to the line c, c. The outlet pipe is shewn at d, f, having a valve
at f, and the inlet pipe at g, h, having a valve at g. i, i, are pullies over
which a chain or rope passes to suspend the vessel a, a, a, a, and at the other
end connected with the counterbalance or weight k, which, exceeding the
weight of the inverted vessel, has a constant tendency to draw up the same,
and thereby produce the effect of exhaustion, as before described. In this
arrangement, when the inverted vessel is full of air, gas, or other elastic fluid,
the weight & must be diminished, and the pressure of the vessel itself will
propel or drive forward the air or other product contained therein by the
outlet pipe d, f, the valves at 9 and f reversing their action as before described
in in 1

page_text: Fig. 3 represents a sectional clevation of another arrangement of
machinery, where a single inverted vessel effects a continuous tendency to
exhaustion, and propels the air, gas, or other elastic vapour, as before
described. a, a, a, a, is a vessel, completely closed and filled to the line b, b,
with water or other suitable liquid. c, c, c, c, is an inverted vessel suspended
by the rod d, d, passing through a stuffing box or collar of leather at the
pointe, by which rod the aforesaid vessel is alternately raised and lowered, as
beforo described, by any adequate power or first mover. f, h, is an inlet pipe
having a valvo at f opening towards the interior of the vessel a, a, a, a, and
i, k, is an outlet pipe with a valve at k opening towards the interior of the
trunk 1, 1, 1, 2, which leads the air or gas to its destination. m, n, is the outlet
pipe to the interior of the inverted vessel, as before described, and o, p, the
inlet pipe, having severally the same arrangement of valves as in Fig. 1. By
this arrangement a partial vacuum is formed by the alternating motion
imparted by the rod d, d, both in the inside of the vessel c, c, c, c, and in the
upper part of the closed vessel a, a, a, a, thereby causing a continuous exhaus-
tion or tendency towards vacuum in the pipes or tubes thereto connected, and
leading to the furnace, as before described, and also propelling the air, smoke,
gas, or other airiform product therefrom, extracted by the outlet pipes i, k,
and m, m, n, into the trunk l, 1, 1, 2, and thence through any arrangements of
the manufacture to which the principle is applied.
Having now described, with reference to the annexed Drawing, my Invention
of an Apparatus for Exhausting, Condensing, or Propelling Air, Smoke, Gas,
or other Airiform Products, I do hereby declare that I confine my claim of
Invention, not only to the several arrangements of my apparatus as herein-
before described, but to the application of the principle of exhaustion caused
by mechanism raising a vessel inverted in water or other suitable liquid. The
form, proportion, and also the material of which the vessels, tubes, and other
parts of the apparatus are to be constructed must depend on the nature and
amount of air, gas, smoke, or other airiform product to be operated on,
governed by circumstances, without in any way departing from the object of
my Invention as herein-before described and set forth.
In witness whereof, I, the said Simeon Broadmeadow, have hereunto
set my hand and seal, this First day of October, in the year of our
Lord One thousand eight hundred and twenty-five.
(L.S.) SIMEON BROADMEADOW.
