PROVISIONAL SPECIFICATION.
Improvements relating to the Burning of Liquid Fuel in Boiler
Furnaces and the like.
I HERBERT JOHN HADDAN of the firm of Herbert & Co. Patent Agents of
18 Buckingham Street Strand W.C. in the County of Middlesex, Civil Engineer
do hereby declare the nature of this invention a communication to me from abroad by
Francesco Fazio Amoroso of Venice in the Kingdom of Italy, Engineer, to be as
follows:-
This invention relates to the burning of liquid fuel in boiler furnaces and other
furnaces to which the method of heating is applicable.
The furnace is provided with an open tank or tray of convenient shape and size
to cover the area of the furnace and of sufficient depth to hold a moderate quantity
of the fuel. Over this tray are journalled horizontally revolving perforated cylindors
or rotary bodies provided with radiating wicks of asbestos or the like. These are
caused to revolve so that the wicks in rotation are dipped to a greater or less distance
(according to the amount of fuel to be burnt) into the fuel and so become saturated
with more or less and burn with a fierce flame.
The rotation of the wick holders may be done by the engine driven by the steam
from the boiler or by an independent engine or motor. While steam is being raised
in the boiler heated by the improved furnace the wick holders may be revolved by
hand or by an independent engine.
The shallow wick tank is in connection with a fuel reservoir, the communication
being controlled by a ball cock or float valve so that a constant level of fuel is
maintained in the wick tank.

Improvements relating to the Burning of Liquid Fuel in Boiler
Furnaces and the like.
I, HERBERT JOHN HADDAN, of the firm of Herbert & Co., Patent Agents, of
18, Buckingham Street, Strand, W.C. London, in the County of Middlesex, Civil
Engineer, do hereby declare the nature of this invention, a communication to me
from abroad by Francesco Fazio Amoroso, of Venice, in the Kingdom of Italy,
Engineer, 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 the burning of liquid fuel in boiler furnaces and other
furnaces to which the method of heating is applicable.
The furnace is provided with an open tank or tray of convenient shape and size to
cover the area of the furnace and of sufficient depth to hold a moderate quantity of
the fuel. Over this tray are journalled horizontally revolving perforated cylinders or
rotary bodies provided with radiating wicks of asbestos or the like. These are caused
to revolve so that the wicks in rotation are dipped to a greater or less distance
(according to the amount of fuel to be burnt) into the fuel and so become saturated
with more or less and burn with a fierce flame.
The rotation of the wick bolders may be done by the engine driven by the steam
from the boiler, or by an independent engine or motor. While steam is being raised
in the boiler heated by the improved furnace, the wick holders may be revolved by
hand or by an independent engine.

fuel is maintained in the wick tank.

Reference being made to the accompanying drawing. The tube b, Fig. 1, the
opening of which is regulated by the cock o brings the oil from the reservoir V to
the fire-place B the end of the tube b having a valve h that regulates automatically the
entering of the oil.
In the fire-place or tank are arranged the horizontal and parallel hollow cylinders C,
Figs. 1, 2, 3, 4, and 8, upon which are fixed with metallic bands (in Figs. 3 and 4).
amianthos or asbestos wicks a perpendicular to the axes of the cylinders.
2"
An auxiliary engine A, Figs. 2, 7, and 8, sets these cylinders C in motion by an
external gearing Fig. 2 until the principal engine goes under pressure and the latter
can then be used to produce the movement.
The cylinders and the wicks are immersed in the oil to the depth necessary to
regulate combustion.
The shape of the tank may be circular for vertical boilers G, Fig. 1, and quad-
rangular for horizontal locomotive boilers of the usual system B, Fig. 7, or the latter
may be arranged somewhat after the manner of Cornish boilers with tubular uptakes
from the main.horizontal tubes as shown in Figs. 5, 6 and 8.
The advantages of the new fire-place are:
1st. The continuous automatic and noiseless feed which permits the regular
production of steam.
2nd. The perfect combustion of oil and the absence of ashes.
3rd. The easiness of blowing out the flame in the case of danger by shutting the
openings for the air T, Figs. 1 and 6, and the cock o Fig. 1.
4th. The best distribution of the flame and therefore the possibility of using the
greatest quantity of heat, Figs: 1, 5 and 8.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is:
--
The means for burning oil consisting of an open tank or tray for receiving said oil
and a system of rotary wick holders dipping into said tank or tray substantially as and
for the purpose described.
