PROVISIONAL SPECIFICATION.
Improvements in Means for Consuming Smoke.
We, SAMUEL HOYLE, of the firm of A. & J. Hoyle, of 27, Park Street, Cotton
Manufacturer, and ADAM HASLAM, of 9, Park Street, Mechanical Engineer, both
of Radcliffe, in the County of Lancaster, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is to consume the smoke arising from furnaces in a
more effective and simple manner than heretofore has been the case, by causing
the same to come into contact with a current of hot gases from the furnace
immediately behind the fire bridge, which hot gases burn the smoke.
To this end our invention consists in building into the fire bridge a box or other-
wise forming the same with a chamber which is in communication with the furnace
and with the space at the back of the fire bridge. The upper part of the front of
the said box or chamber, we form with a grid communicating with the furnace
space above the fire bars, while the part below the said grid is open and in com-
munication with the furnace space below the fire bars. The upper end of the said
box or chamber behind the fire bridge we also form with a grid so as to permit the
hot gases which enter the said box or chamber from above and below the fire bars
to issne therefrom and meet the smoke passing over the fire bridge, thus burning it
immediately.

COMPLETE SPECIFICATION.
Improvements in Means for Consuming Smoke.
We, SAMUEL HOYLE, of the firm of A. & J. Hoyle, of 27, Park Street, Cotton
Manufacturer, and ADAM HASLAM, of 9, Park Street, Mechanical Engineer, both
of Radcliffe, in the County of Lancaster, do hereby declare the nature of this
invention and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The object of this invention is to consume the smoke arising from furnaces in
a more effective and simple manner than heretofore has been the case, by causing
the same to come into contact with a current of hot gases from the furnace
immediately behind the fire bridge, which hot gases burn the smoke.
And in order that our invention may be more fully understood I have caused to
be appended hereunto one sheet of drawings marked with letters of reference
indicating like parts in the various figures.
Fig. 1 is a longitudinal section, Fig. 2 a plan, and Fig. 3 a cross section on
line A-B of Fig. 1 of a boiler flue provided with our improved means for
consuming smoke.
In carrying out our invention and referring to the figures generally, the
improvements consist in building into the fire bridge a or otherwise forming the
same with a box or chamber b which is in communication with the furnace and with
the space at the back of the fire bridge o a. The upper part of the front of the box or
chamber b, we form with a grid d, which provides passages d' communicating
with the furnace space c above the fire bars e, whilst the part d² below the
grid d is open and in communication with the furnace space c¹ below the fire
bars e.
The upper end of the box or chamber 6 behind the fire bridge a, we

page_text: also form with a grid f, providing passages f, to permit the hot gases and cool
air, which enter the box or chamber b respectively from above and below the fire
bars e to issue therefrom and meet the smoke passing over the fire bridge a thus
burning it immediately, the residue falling either through the grid f into the box
or chamber 6 or behind the fire bridge a from which it may be readily removed
from time to time.
The box or chamber 6 with its grids d & f may be cast in one piece, as shown in
the drawing or it may be built into the fire bridge a in parts as may be found most
convenient.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what we
claim, is―
"In means for consuming smoke"
The application to a fire bridge a, or formation therein, of a box or chamber b,
the front and back of which are formed with passages d', ', & fi adapted to
permit, respectively, the passage of hot gases and cool air from above and below
the fire bars e through the box or chamber b, to the back of the fire bridge a,
substantially as and for the purpose set forth.
