anrough the compey breast and 'soot trap.
Fig. 3 is a plan of the same.
Fig. 4 a detail.
A is a fire place a. a. a are its flues, D the filter, E the soot trap, Fajet or jets
of compressed air or steam supplied by the pipe b for creating a drait for the
fire A and in the flue a, and is assisted by one or more jets below and above the fire,
or both, that act as a bellows and complete combustion.
The filter D has a back valve c, Fig. 4, doors d and e, pairs of semi circular
perforated plates 9. fand a dish which is supplied with liquid through a cone or
pipe K and has an overflow : it is charged with strata of coke and charcoal
which varies in size in each strata, the smaller being at the dish; and so that each
strata retains the adjoining in place. The flue a and soot trap E has a door m

is attached so that when the door m is operated through the link lever s rocking
shaft t and handle u, the sieve p works with it, and allows an adjustable amount of
the gas and products of combustion from the fire A to pass to the filter D while
more or less, with the larger of the soot passes into and is retained in the trap E
by the sieved exit through which the hot gases pass by the pipe w to the burs
of the fender L, chimney piece or grate front M, or to the bars of a drying horse
not shown, and to the hollow grate sides N, and the coil O, and so assists the fire,

WORKING.
The fire A being lit the jets F and Fa are turned on, and also Fb when steam
is available and it is desired to direct the grosser products over the length of the
fire, and create a partial vacuum and assist the draft and thus together direct the
gases up the flue a the lighter pass through the door p, are drawn by the jets F
into the filter D: the heavier products are deflected by the door m into the soot
trap E and settle, the gases pass through the sieve v, pipe w, grate chambers and'
other pipes assist the fire, reenter flue a at x by pipe Y and are drawn into the
filter D, they pass through valve c, Fig. 4, plate and the strata of coke and
charcoal into the vessel of liquid, overflowing its edges, is redistributed by and
passes through plate g, to pipe y and the atmosphere.
The soot, when necessary is blown from trap E through tap when a tap Wa in
pipe to is closed.
The cupboard door Z enables examination of filter D through its doors d and e
or the whole to be taken out after detaching pipes at their unions.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
Providing fires with jets of air or steam to facilitate combustion of their
products, and to thrust them forward in a flue toward other jet or jets fixed so that
they may draw and thrust such products into a filter formed with a back valve,
pairs of semi circular perforated plates, a dish for liquid with supply and overflow
pipes, strata of varying sizes of coke and charcoal for filling up the dish and the
whole filter, an exit pipe leading to the atmosphere, or elsewhere, and doors for
examination filling and emptying: for a soot trap to receive the heavier gasses and
larger products of combustion having an entrance regulateable by the said door, a
top sieved exit which shall retain the larger products but let the heat and gasses
pass on to a coil, hollow grate sides, bars, or chimney piece, hollow dogs, fender
bars, drying horse bars and back to the flue and be thrust by the said jet or jets
into the filter: a bottom exit through which to abstract the soot when its tap is
turned on and that in the other exit turned off: for the said double hinged
adjustable doors one of which is a sieve fixed in the flue to direct the said gasses
and products to the filter and soot trap substantially as described.
