Improvements in Heating and Smoke Consuming Apparatus.
I, GARRETT WALLACE POOLE, of 28 Arch Street, Newark, County of Essex
and State of New Jersey, U.S.A., Builder, do hereby declare the nature of my
invention, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention relates to a new and useful improvement in heating, and smoke
consuming apparatus, and it consists in the combination and arrangement of parts
and details bereinafter set forth and claimed.
My invention is illustrated in the accompanying drawings, in which
Figure 1 is a side elevation of the interior of a building and of my improved
apparatus in position;
Figure 2 is an enlarged side elevation partly sectioned of the chamber designed
to receive the unpurified smoke from the furnace;
Figure 3 is a similar view of the chamber in which the smoke is purified ;
Figure 4 is a cross section taken on the line x-x of Fig. 2;
Figure 5 is a cross section taken on the line y-y of Fig. 3;
Figure 6 illustrates my improved apparatus, constructed and adapted for smoke
consuming only and
Fig. 7 a cross section on the line 2-2 of Fig. 6.
In said drawings (Figs. 1 to 5 inclusive) A represents an engine of usual
construction, communicating motion through shaft B and pulleys to a fan or
blower j.
At one side of the engine A is arranged the furnace a, within which an
ordinary boiler is placed. Leading from the dome of the furnace a is the fuel or
smoke pipe b provided with a damper e.
This smoke pipe enters a chamber d and smoke leaves said chamber d through
pipe provided with a damper h, which pipe f enters the usual chimney g (see
Figure 1). The blower is provided with two outlet pipes i and k, the lower
one (k) of which enters the furnace a beneath the grate bar m thereof, and is
provided with a damper. The upper pipe i is provided with a damper i¹ and
extends through the chamber d into the funnel shaped pipe n, which has an opening
into said chamber d. This pipe is provided with a damper n¹ and enters a
chamber o, preferably at the lower end thereof.
From said chamber o leads a pipe p into the furnace a below the grate m, while
a branch tube 9 enters said furnace above said grate, as clearly shown in Fig. 1 of
the drawings.
Said pipes p and 7 are provided with dampers p' and q' respectively.
From the pipe n and on either side of its damper n lead the pipes r and 8,
provided with dampers and s¹ respectively. These pipes rands are respectively
the inlet and outlet pipes to and from a system of heating pipes v and radiators t.
The pipe s has an outlet v into the open air, provided with a damper v', see Fig. 1.
Leading from the steam dome c of the boiler is a pipe c', which terminates inside
the chambers d in a semi-dome shaped case d', the under wall d' of which is
perforated as at d (see Fig. 2).
Arranged on the side of the chamber d above the mouth of pipe b is a deflecting
plate for the purpose hereinafter described.
Also leading from said steam dome c is another steam pipe entering the
chamber o and terminating in a cylindrical chamber o", having an upper wall o' aud
a lower wall o³.
The lower wall is perforated by minute orifices o³.
the chamber o into two compartments, and is placed
This chamber of separates
below the mouth of pipe p

page_text: (see Fig. 3). Communication between the two compartments of chamber o is
effected by tubes of extending through the walls o¹ o' and the entire chamber o*.
In operation, when the apparatus is to be used for smoke consuming, the
dampers i', n', e and q' are opened, whilst the dampers r¹, s¹, p' and k' are closed.
The damper is opened wholly or partly as may be necessary to allow excess of
smoke from the furnace to escape into the chimney g.
In this position smoke from the furnace a ascends into chambers d, wherein it is
sprayed by minute jets of steam from orifices d' of the semi dome shaped chamber d',
and in this chamber d the smoke is deflected by plate d towards the wall d³ and
towards the outlet pipe n. Air is now forced into the funnel shaped end of pipe n
from the blower through pipe i (damper being open) and the suction thus
produced in pipe n serves to draw in the sprayed smoke from the chamber d. The
air and smoke is then forced through pipe n (dampers r¹ and s being closed and n'
open) into the chamber o below the cylindrical partition of. The compartment
below said partition of is preferably filled or partly filled with sawdust (not shown)
or similar matters, through which the air and smoke are strained. In this com-
partment the combined air and smoke are sprayed by steam from the orifices of in
the under wall o² of the partition 0%, and the sprayed air and smoke are then
forced through the tubes of into the upper compartment from whence it enters the
pipe p.
The combined air and smoke is then forced through pipe q (damper q' being
open and damper p¹ closed) into the fire chamber above the grate a', where it is
consumed.
The products of combustion can be utilized for heating purposes; the dampers i¹,
e, r, and pl are all opened, whilst the dampers n' h and q' are closed.
The
When air is forced through pipe i into pipe n, it mingles with the smoke and hot
air of chamber d, (by reason of the well known siphon action) in said tube n.
damper n¹ being closed and damper open, the smoke and air combined is next
.forced through pipe r into the heating pipes and radiators t.
From the radiators
the combined smoke and air passes through pipes (damper & being open) into the
tube n on the other side of the damper n. The spent smoke and hot air combined
is then forced through chamber o and through pipe p below the grate and serves
to increase the blast or draft. When still greater blast is required the damper k¹
may be opened, and air directly from the blower j, fed below the grate a¹.
It is manifest that with proper regulation of the various dampers heating and
smoke consuming may be performed at the same time. In Fig. 6 of the drawings
I have illustrated my improved apparatus constructed and adapted for smoke
consuming only. In said form the steam spraying chamber d is done away with,
and the smoke pipe 6 enters into the enlarged portion of pipe n, which latter is
likewise connected by tube with the chimney. The pipe i, leading from the
blower extends into said enlarged portion of pipe n, which latter is also provided
with sliding dampers no, by means of which the direction and current of the smoke
from pipe can be easily regulated, as will be manifest.
In said drawing is also shown a modified form of purifying chamber. Said
chamber (o) is provided at or near its top with a perforated partition plate of,
dividing said chamber into two compartments o' and o³, the upper one of which is
steadily supplied with fresh water through inlet pipe o³.
The lower compartment o³ is provided with a partition 10 extending upwards to
a short distance from the perforated plate 0%. In said chamber o, and by the
extending portion of the plate 010 together with the upright partition o" is also
formed a trap o¹ which prevents the smoke (entering said chamber through pipe n,)
froin passing out of said chamber, except through pipe p. The smoke in its
passage through chamber o is subjected to a shower of water which descends from
chamber of through the perforations in plate o, and is thus cooled and purified.
The debris and impurities from said smoke accumulate in the lower portion of
chamber o and can easily be removed by opening the manhole o¹. The surplus of
water leaves the chamber o through outlet pipe o³. The smoke after being purified

page_text: passes through pipe p (having damper p¹) and through pipe q (with damper q) into.
the furnace, as heretobefore described."
If preferred the pipe 9 may communicate with a perforated annular chamber a²,.
whereby a better distribution of the smoke is obtained. (The hollow grate bars a¹
is connected with the steam generating pipes, to prevent them from being burned
out.)
Having now particularly described and ascertained the nature of my said inven-.
tion, and in what manner the same is to be performed, I declare that what I
claim, is:
1. In a smoke consuming apparatus, the combination of a furnace, and the steam
dome of its boiler, a chamber adapted to receive the smoke from said furnace, a
blower and siphon adapted to suck the smoke from said chamber and to pipes
leading from said siphon to the fire place of the furnace, and with a steam pipe
leading from the steam dome to said chamber, all arranged so that the combined
