Improvements in Stoves for Burning Petroleum.
I, HENRY JUSTINIAN NEWCOME, Shenley, Hertfordshire Clergyman do hereby
declare the nature of this invention to be as follows:-
I place in a stove having two outlets an iron box or pan filled with sawdust or
other fuel saturated with Petroleum. The one outlet leads direct to the chimney and
can be closed with a valve when required. The other outlet leads to a number of thin
metal tubes which return once or more times and through which the heated products
of combustion. travel horizontally until the heat has been nearly exhausted when
the fumes return to the chimney or flue. In the top of the stove a small iron pipe is
inserted which discharges the Petroleum into the centre of the burning fuel. This
pipe bent like a syphon terminates in a reservoir which is supplied from a vessel with
a tap by which the petroleum is allowed to flow into the reservoir in exactly the
required quantity. The Tubular Portion of this apparatus is that of a Locomotive
Boiler without the outer casing with the flue opening on the top of the fire box.
Where instant heat is wished for an additional pan of sawdust may be placed in the
further end of the Apparatus called in a Locomotive the Smoke box, or connected
with it and supplied with Petroleum in a similar manner as before described. The
ends of the apparatus can be removed for the easy cleansing the tubes, which should
be kept as clean as possible.

page_text: HENRY JUSTINIAN NEWCOME Shenley Herts Clergyman, 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 :-
Whereas Petroleum has usually hitherto been burnt with wicks and metal covers to
consume the smoke, I propose to obtain warmth from it by consuming it in increased
quantities and by burning it in any furnace or close stove in the following manner.
If a fire is already burning, I pour from a vessel containing petroleum through a pipe
which enters the top of the stove or furnace and may be perforated in several places
a stream regulated by a stop cock over the burning fuel, whereby a nearly instan-
taneous increase of flame is obtained. Where fuel is not burning, I insert between
the bars of the stove or upon the bars of the furnace a shallow metal tray filled with
sawdust or other material in which is imbedded a metal tube folded up in lengths .if
required, and perforated throughout with minute holes through which the petroleum
saturates the sawdust. This tube is connected with the vessel above named and the
flow of Petroleum is regulated by a stop-cock. When required for use, the sawdust is
saturated with the Petroleum, and with a lighted match an instantaneous flame is
produced.
To utilize the heat so obtained, by a close fitting damper or valve placed in the
chimney, or flue pipe, the ascending heated fumes are diverted through a series of
horizontal tubes of thin metal and of any dimensions and length, and which by
various returns delay the escape of the smoke until the heat is nearly exhausted.
This arrangement of tubes I call a Multitubular Chimney and is of the nature of a
Locomotive Boiler deprived of its external casing, all the tubes terminating at both
ends in a Chamber or smoke Box the doors of which can be readily opened and the
tubes swept clean throughout. In these Chambers are placed the necessary partitions
to form the returns above mentioned. An arrangement should be made, which will
vary according to circumstances, that whenever the door of the furnace or stove is
opened when the Petroleum is burning, the valve to the direct chimney or flue should
be opened a moment previously to prevent an explosion of gas through the furnace
door: At the outlet flue an opening with a sliding door should be made in which paper
soaked in petroleum should be lighted to establish a draught through the Multitubular
Chimney whenever the petroleum in the stove is first set on fire. The lighted.
Petroleum may be instantly extinguished by sawdust thrown over it.
In conclusion I do not limit myself to the precise method as shewn in the accom-
panying drawings, the Apparatus being capable of indefinite extension, it being
possible to consume in a large Apparatus a half barrel of Parafin in the same time as
a pint in a small one without wasted heat, and as every pound of fuel contains so much
heating power, it is manifestly desirable to obtain that warmth in as short a time as
possible, especially where large buildings are required for use for only a short
period.

page_text: Description of the drawings of the Stove and Multitubular Chimney for burning
Petroleum without the use of cotton wicks.
A is the opening to the Stove, the door of which sliding upwards raises by a rod
the valve B and so allows the heated smoke to escape direct into the flue pipe C and
into the outer air. When B is shut, the heated tubes traverse the tubes of the
Multitubular Chimney and return above B into the flue C a large portion of the heat
being exhausted. When coal or other fuel is being used by opening the tap E in the
pipe leading from the reservoir D which is filled with Petroleum, a regulated stream
is poured through the top of the Stove upon the burning fuel, thereby instantaneously
increasing by many degrees its heating powers. If fuel is not burning and immediate
temporary warmth is desired, a shallow tray filled with sawdust in which is imbedded
a perforated tube is placed between the bars and connected with the tube F, when by
opening the tap in F the sawdust becomes saturated with Petroleum, and may be
instantaneously ignited. A second Stove is shewn which when necessary may be
brought into action in a similar manner. The horizontal Chimney may be extended
to any length required. H are Circular Covers which can be easily removed to allow
the tubes to be swept throughout. A I there is a small opening through which paper
soaked in Petroleum may be introduced to establish a draught through the tubes.
J should be kept close when the Stove is not in use. The difference in the degrees of
heat in the direct Chimney C and that obtained after permeating the tubes should be
tested with a Special Thermometer as any common one would immediately burst.
Fig. 2 shews a section of the Multitubular Chimney.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is to be performed I declare that what I claim is-
1st. The power of consuming Petroleum for warming purposes without the usual
cotton wicks and metal caps and in larger quantities than in any existing Stoves.
2nd. That by preventing the burning products of combustion vitiating the
Atmosphere of the Apartment I do away with the offensive odours that most
Petroleum stoves throw off.
3rdly. That the utmost warmth is economically obtained from burning fuel by passing
the heated fumes through thin metal tubes which are exposed to the atmosphere and
a perfect system of ventilation is secured if the Apparatus is so placed as to com-
municate with the external air and discharge it warm and pure into the Apartment
where it is placed.
