Ross' PATENT LIGHTING Co. Ld. 32 & 33 Wicklow Street Dublin Lighting Engineers
and JOHN HOWARD Ross Manager Dublin do hereby declare the nature of this
invention to be as follows:-
The application to concentric argand burners for burning coal gas or vapour of
hydro-carbon or other oils, of concentric deflectors surrounding & between the flames
for the purpose of producing more perfect combustion in burners having a forced air
supply, by causing the air to impinge on to either or both, the inside or outside of
each flame & also the application to aforesaid burners of a cone & nozzel, or cones &
nozzels, whereby a saving in the quantity of forced air required is effected, by the
introduction of currents of the surrounding atmosphere.
These improvements are to be applied to gas or vapour burners in a similar manner
to that described in specification No. 7470' dated 19th June 1885 taken out by the
aforesaid J. H. Ross and another.

We, Ross' PATENT LIGHTING COMPANY Limited of 32 and 33 Wicklow Street
Dublin Lighting Engineers and JOHN HOWARD Ross, Manager, Dublin 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:
In Letters Patent 7470 of 1885 granted to John Howard Ross and one Archibald
Mackenzie the Younger an arrangement of argand or concentric wick oil burner is
shown having deflectors surrounding and between the flames to deflect a forced air
supply produced by mechanical means on to such flames either on the outside or the
inside or on both sides.
The forced air entered through a nozzle carried by or fitted to a frame or globe
having perforated sides through which atmospheric air was free to enter and passed
with the forced blast up a cone to circulate among the argand or concentric wick
burners.
Our present invention is designed to apply such deflectors and nozzles and cones
to argand or concentric ring burners using coal gas or oil or other hydrocarbon
vapour.
Referring to the accompanying drawings.
Figure 1 is a vertical section of a lighthouse burner constructed according to our
invention.
Figure 2 a sectional plan of same on the line a-b of Figure 1.
Referring to Figure 1 more particularly A is the foundation or base of the burner
carrying a cone or nozzle B. From a flange C on this foundation or base depends an
open work frame or globe D closed at its bottom and carrying or fitted to a nozzle E
through which the forced draught is supplied to the burner.
Atmospheric air can enter or be sucked in through slots surrounding the sides of D
(as shown by the arrows).
The said frame or globe D protecting the current from the nozzle E from side
draught.
The foundation or base A is shewn bored out or otherwise suitably formed
at F. G. H. I to receive pipes or conduits F¹ G'H'I' fitting the said foundation or
base. Supported from these pipes or conduits is a flanged ring J carrying a plate or
disc K and this plate or disc carries a series of rings L. L' L placed concentrically.
Over these rings a plate or disc M is placed into which are fitted tubes M³ carrying or
supporting concentric burners M³ of suitable construction entering the space between
each ring and opening into such spaces to receive gas supplied from the pipes or
conduits FG¹ H'I'.
The burners M² are constructed of annuli split or perforated or formed with a gas
passage similar to an Argand burner at the top and closed at the bottom save where
entered by tubes M¹ placed at intervals on the plate or disc M and entering the gas
passages between the rings so that the gas entering between the concentric

page_text: rings L. L L and J has free access to the tubes M' and so to the ring burners M³,
the object being to allow free circulation of air between the tubes and the burners.
The pipes or conduits F¹G¹ H¹1' are so disposed as to feed to the spaces between
the different rings or to the central space N.
Thus F feeds to the central space N. G¹ feeds to the space between rings L and L'.
H' feeds to the space between L' and L-I feeds to the space between L' and J.
Taps or valves as shown are fitted to the pipes to control the flow of gas which pass
to all or any of the series of concentric ring burners in desired volume. The pipes or
conduits are connected through the taps to a common circular pipe or main fed from
the gas or oil vapour supply as shown, the inlet to it being indicated by dotted lines
but it can be of course affixed at any point.
A gauze cone P is shown placed in an inverted position resting on the ring J and
with its upper end abutting on the apex of the cone Q surrounding the concentric
burners, from which continues a cylinder or body S the top of which is formed to
constitute the outermost deflector.
The forced air current and the induced air current enter the annular cone formed
by the junction of P and Q and the velocity and volume of the air current being
checked by the ascending contracted passage, the air supply is economized.
The forced air blast entering the nozzle E may be supplied by fan, bellows or other
mechanical means and the induced air enters the frame or globe D and passes up the
cone or nozzle B and circulates round the tubes supporting the concentric ring
burners and between the same as shown by the arrows..
The dotted lines between the concentric ring burners (on the drawings) represent
stays or supports placed at intervals between the same to carry the deflectors R R¹ R² R³
which may be made of suitable metal or other substance resisting the destructive
action of heat.
As shown, they are approximately Y-sectioned and so arranged as to deflect the
air current on each side of the flames produced from the concentric ring burners but
this arrangement of the deflectors may be altered so as to deflect the air current on
the inside or outside only of the flames if desired.
T is a top deflector mounted on the rod U to deflect the escaping current on to the
flames as described in Letters Patent 7470 of 1885.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is-
Firstly. In argand or concentric ring burners burning coal gas or oil vapour or other
hydrocarbon vapour and using a forced air supply produced by mechanical means-
the application of deflectors surrounding and between the flames substantially as
described and with reference to Letters Patent No. 7470 of 1885.
Secondly. In argand or concentric ring burners burning coal gas or oil vapour or
other hydrocarbon vapour and using a forced air supply produced by mechanical
means the application thereto of the cone or nozzle or cones or nozzles substantially
as described and with reference to Letters Patent No. 7470 of 1885.
