I, GEORGE RYDILL, of Dewsbury, in the County of York, do hereby declare
the nature of the said Invention for "AN IMPROVED CORNISH OR OTHER STEAM
BOILER, WITH SMOKE CONSUMER AND CONDENSER, BEING ALSO APPLICABLE FOR
VENTILATION," to be as follows:-
My improvements consist of an improved steam Cornish or other boiler, with
smoke consumer and condenser, and in order to carry out the same I cut a
hole through the tubes or flues of a Cornish or other boiler, so that the grate
bars are fixed at the bottom of the tubes or flues, by which means the whole
area of the fire-box becomes heated, shutting up the whole of the space which
is now used to admit cold air. The fire receives its air from the bottom or
sides of the boiler so formed that a culvert or subterranean passage conducts
the air to the fire, by which means a powerful blast draft is obtained, enabling
the proprietors of steam boilers to save a vast amount of fuel, and also enables
them to consume the worst coal. I fix a draught ash box to admit air to the
grate bars where the culvert of air passage is not fixed. Instead of the brick
wall now in use, I construct the bridge at the end of grate bars of boiler plates
to form a water space, so that the fire has heating surface on every side.
Where practicable, a furnace should be built of brick, and its draft obtained
by means of a culvert or air passage to be fixed at the end of boiler or boilers.

page_text: By this means one or more, or half a dozen boilers can be heated by one fire.
Furnaces of any description obtaining draft by means of air passages or culverts
have a powerful influence to consume smoke.
As machinery to work a fan might at times be inconvenient, I find, that by
setting the boiler inner flue with fire-bricks, with a chequered roof or plain invert,
the ash-place or box with bricks and a tongue and groove fitting into each
other at the bottom, top, and ends, will give every satisfaction. I place in the
flue any kind of openwork of iron, copper, brickwork, or stone. The brick-
work fixed round the fire forms a retort which gives a steady heat to the boiler.
The smoke from the fire or fires passes into a flue or flues, where it is played
upon by water springers, hot or cold, being used, and is conveyed from the
boiler or boilers by means of a pipe or pipes, the water playing amongst the
smoke as it travels along towards the chimney causes a combustion and a con-
densation to take place, which washes the carbon and sulphur out of the heated
body, which makes its way out of the flue into a vessel leaving a white vapour
to rise from the chimney. The draft created by the pressure of water from the
boiler or boilers is so great that no chimney is required to create a draft,
Jongitudinal pipes fixed in the flue containing water answer the same purpose
as a tubular boiler. The water that is thrown into the flues, chimneys, or
openings by the springers or other means, is collected, being valuable for
chemical purposes.
In adapting my Invention to a railway or any other kind of engine, having
an outward casing over or around the boiler, at the same time receiving air
underneath the cover, or at any other part, I allow the air which will be
collected to enter the fire box through openings in or over the fire, the same
will allow the fire box door to be closed; the steam jet which is now used to
cause a draft and condense the smoke, can be dispensed with by the water
springers being introduced, which will condense the smoke, the smoke of the
engine chimney to be carried through a tube or tubes, where water springers
are fixed, they receive the water from a boiler.
In the case of steam ships, the vapour can be worked behind the vessel or
out of the sides, or otherwise, by means of the water springers, the springers
throwing out the water to condense the smoke, hot air can be taken over the
door the same as in any other fire box. This principle of draught and venti-
lation will allow boiler houses, engine rooms, cabins, or any place whatsoever,.
on sea or land, to be well and perfectly ventilated.
The smoke of iron works, where smelting and other furnaces are used, can
be condensed along a tube or pipe, and conducted over the fire-place door of
any boiler, provision being made for that purpose, and with the aid of a little

page_text: fire and air; this smoke can be consumed partially, and all the carbon is
condensed, so that there remains a simple vapour without nuisance. Smoke
from whatever source it comes from, can be consumed and condensed by water,
applied either by machinery or otherwise, or the smoke conducted into a flue,
where the hot and cold water springers are placed.
Dust arising from any machines, cotton mills, grinding mills, or factories,
can be condensed by hot or cold water springers or steam, which causes a
draught, thus saving the working of a fan, the dust thereby collected being
taken away.
An improved grate bar is easily made, and so formed as to answer the
purpose of this Invention preventing the bar from running and expanding as
the variation of the bar causes different draughts to act upon it by the cover
of the fire, and causing the air to act more upon the sides of the grate bar,
and giving a greater regularity of draught.
