Office of the Commissioners of Patents, with his Petition, on the
3d March 1853.
(Void by reason of notice to proceed not having been given within the
time prescribed by the Act.)
I, SIMON O'REGAN, of Belfast, do hereby declare the nature of the
said Invention for "IMPROVEMENTS IN APPARATUS FOR CONSUMING SMOKE
to be as follows:-
This Invention consists in certain new mechanical arrangements and
combinations of parts, having for their object the proper admission of
air into chambers, hollow bridges, and slides, to support combustion of
the fuel in furnaces; and such air is caused to pass through perforated
plates before coming into contact with the smoke and flame from the
fuel; and further, in a simple and effective mode of admitting, shut-
ting off, and regulating the supply of air to furnaces. And this may
be effected in the manner exhibited by the illustrative drawings here-
unto annexed, reference being had to the numeral figures and letters
of reference marked thereon respectively, and the following description
thereof.

page_text: DESCRIPTION OF THE DRAWINGS.
At Sheet 1, Fig. 1, exhibits a longitudinal and vertical section of a
cylindrical-shaped boiler and furnace for consuming smoke, constructed
according to this Invention; Fig. 2, is a transverse and vertical sec-
tion taken through the line A, B, at Fig. 1; Fig. 3, is an end view
of a boiler, shewing the construction of some of the parts hereafter
referred to. At Sheet 2, Fig. 4, exhibits a longitudinal and vertical
section of a cylindrical-shaped boiler and furnace, shewing another
mode of arranging and disposing the several parts employed for
effecting the consumption of smoke. Fig. 5, is a longitudinal section;
and Fig. 6, a top plan view of a portion of a furnace arranged and
combined according to this Invention. At Sheet 3, Figs. 7, 8, 9, 10, 11,
12, 13, exhibit several views of parts hereafter described and referred
to, drawn to an enlarged scale. At each of the above-mentioned
sheets of drawings, similar letters of reference are employed to denote
corresponding parts. At Sheet 1, A, B, mark a furnace; C. 1, 2, is a
hollow cast-iron bridge, placed upon a brick chamber G. The bridge
C, is formed of two parts, 1, and 2; the part 1, is formed solid, and the
part 2, has perforations formed through it, as shewn at Fig. 1, of
Sheet 1, and Figs. 7, and 8. of Sheet 3. D, marks another hollow
bridge, denominated a check air bridge, of similar construction to the
bridge C, 1, 2, but placed in an inverted position beneath the boiler,
and coupled together with stay rods, as shown. E, marks another
check air bridge, of similar construction to the bridges C, 1, 2, and
D, 1, 2. F, marks a perforated plate of 'metal, mounted in a frame c,
(and shown more clearly at Figs. 9. 11, of Sheet 3); said plate is set
over the brick chamber H, and has pivots fixed to or formed thereon,
and fitted into brackets upon the frame c, which admits of the plate E,
being moved in a circular direction by means of the bracket and rod
I, I, connected thereto, as shewn the rod I, extends from the bracket
to tho front of the brickwork of the furnace, to enable the attendant
to cleanse the perforated plate, and so to keep the openings or per-
forations in such said plate as clear and free from obstruction as may
be, to allow the air to pass unimpeded through the same. K, is a

page_text: cast-iron box fitted into the chamber G, through which passes a scraper
for cleansing the chamber H, said chamber being furnished with a
small door to prevent the ingress of air thereto. The hollow bridge
D, is also furnished with a perforated plate, similar to the bridge C,
1, 2. 0, 0, and I, L, mark pipes through which air is admitted into
the chambers C, 1, 2, and G, through valves M, and N, situated at the
outer ends of said pipes. Each of these valves are furnished with slides
or such other convenient means as will effect the proper opening and
closing of the same, and there is an index attached to said valves, by
which the stoker or other person attending the fire is enabled to ascer-
tain and regulate the quantity of air admitted into the furnace for the
purpose of inflaming the products given off therefrom, and thereby to
prevent loss of heat which would otherwise occur. The arrangement
exhibited at the several figures of Sheet 2, of the accompanying
drawings, and constituting improvements in the consumption of smoke,
is as follows:-a, marks the fire-grate door; b, furnace bars; c, hollow
air bridge; d, check air bridge; e, perforated plate over chamber h;
f, check air bridge; y, cast-iron chamber under bridge c; i, pipe for
admission of air to check bridge d; j, pipe for admission of air to
check air chamber and bridge f; k, horizontal pipe, communicating
with the pipes i, and j, and main pipe . At Fig. 3, of Sheet 1, m,
marks an end view of the air pipes lastly above mentioned; n, clearing
box in first chamber. It should be observed that the above-men-
tioned arrangement differs from that before described, with reference
to Sheets 1, and 3, in the following respects: the apparatus employed
for effecting the consumption of smoke is placed within the boiler at
Sheet 2, whereas it is arranged or disposed beneath the boiler at
Sheets 1, and 3: there is also a slight modification of the arrangement
of the pipes employed for the admission of air to the check air bridges
d, and f: in other respects the arrangement and construction of the
several parts is precisely similar to that before mentioned with refer-
ence to Sheets 1, and 3. The arrangement exhibited at Figs. 5,
and 6, of Sheet 2, is for the purpose of enabling the attendant to clear
the furnace bars, and also for the admission of air to the front of the
fire bridge. A, marks a perforated sliding plate, to which is attached

page_text: a rod B, formed with a handle, as shown: the attendant, by pulling the
handle and rod B, allows the air to pass from the asli pit between the
ends of the furnace bars and the front of the fire bridge c; and this
arrangement is applicable to and may be used in combination with
the arrangements herein-before described. And in this manner, and
by these means, this Invention may be carried into practical effect, so
as to constitute improvements in apparatus for the consumption of
smoke, as herein before described, set forth, and represented by the
illustrative drawings hereunto annexed, and forming part of this
Specification.
