CHARLES COOPER, of 24, Stainsby Road, Limehouse, London, E., Engineer,
do hereby declare the nature of this invention to be as follows:-
An arrangement which is suitably fixed to the furnace front or boiler with the
necessary connections for steam to enter carrying with it either hot or cold air
to assist combustion of the consumed gases.
The apparatus consists of a moveable air box or blast pipe with crank spindle.
Two cranks cast in one casting. The crank spindle and air box is carried in
(two) 2 bearings in air box case one on each side made of cast iron.
The above air box or blast pipe is worked from the outside of furnace by a
connecting rod to suit long or short furnaces. Which is to say: It can be ad-
justed readily by the said connecting rod, thus enabling the blast to strike the
fire in the most advantageous and suitable parts on the fire.
The above apparatus is fixed on the furnace -door frame, above the door and
worked by a small jet, or, jets of steam, or compressed air, also can be used with
hot or cold air.

Smoke Consuming Apparatus for Steam Boiler and other Furnaces.
CHARLES COOPER, of 24, Stainsby Road, Poplar, London, E., Engineer, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed to be particularly described and ascertained in and by the following
statement:-
My invention relates to apparatus for admitting hot or cold air, and distributing
the same over the entire length of the furnace, by means of one or more radial
blast nozzles, operated from the outside, by means of a crank or cranks attached
to the splayed nozzle, working within a casing fixed to the inside of the furnace
front plate, tube or firebox.
The said radial blast nozzle is operated from the outside of the firebox, by a rod
sliding in a bearing, and fixed in any desired position by a thumb set screw, or
other simple contrivance, and can be adjusted for long or short furnaces, either
square, oblong or tubular. The elevation or depression of the said air nozzle
covers the whole range of the firebars, and thus secures perfect combustion of the
fuel and gases, and completely annihilating smoke. My said apparatus can be
affixed to any furnace door frame, and worked from the outside by means of a
[Price 8d1

page_text: rod. I use steam or compressed air to induce a sufficient supply of oxygen to
support combustion; or of liquid fuel when such is used. The inflowing air
may be heated in pipes or air boxes conveniently arranged in the flue leading
to the chimney, and thus utilize the waste heat to great advantage. The said
steam jet or jets may be used also to spray oils or other hydro-carbons over the
furnace when, constructed to burn such fuels.
In order that my said invention may be fully understood; I have added two
Sheets of Drawings shewing the same in detail, and in action when applied to an
ordinary Cornish or Lancashire boiler.
Fig. 1 Sheet 1 is a vertical section of the apparatus fixed to the fire door
frame of a boiler.
Fig. 2 is a plan of same partly in section.
Fig. 3 is an end view of the splaying nozzle.
A is the outer air and steam jet box, secured to the furnace door frame E.
The two air inlets B B may receive heated air from pipes arranged within the
main flue leading to the chimney. C is a high pressure steam jet.. .D is.a.door
with a mica covering inserted for observing the action, or for the admission of
air from the outside when desired. F is the steam jet pipe. G is a short
coupling pipe to which is bolted the splaying nozzle box H within the casing I.
J is shaft with one or two cranks cast to, or affixed thereto, and worked by the
rod K, brought to the outside for raising or depressing H so as to direct the forced
blast over every part of the firebars, in order to consume all smoke or unburnt
fuel, which adds greatly to the boilers steaming capacity. When the hot air heat-
ing apparatus is attached, I couple the heated air pipe to one or both sides of the
outer box A.
Fig. 4 Sheet 2 shews the apparatus as applied to boiler M.
N shews the air heating box within the flue leading to the chimney. 00 are
the ordinary flues common to boilers of this type. P is the firebridge.
1. Having now particularly described and ascertained the nature of my said' in-
vention, and in what manner the same is to be performed I declare that I claim :-
First. A radiating nozzle secured within a box, to protect it, for distributing
the cold or hot air, gas oil or steam to a furnace, as and for the purposes de-
scribed.
Second. The combination of a hot air heating apparatus, with my improved
radiating nozzle for economizing fuel for the purpose described.
