PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Burning Liquid Fuel.
I, JOHN LEE OSBORN, of Millbay Engineering Works, Millbay Pier, Plymouth,
in the County of Devon, (a communication to me from abroad by Carl Neuhaus,
of XVII Mazssengasse, 15, Vienna, in the Empire of Austria,) do hereby declare
the nature of this invention to be as follows:-
This invention relates to burning oil for steam boilers and the like. In the
accompanying drawing the complete arrangement of an oil burning apparatus is
shown. Steam to the atomizer A is taken from the auxiliary steam chamber and
separator B by opening the steam valve a, which causes the steam to blow through
the fine opening c of the above mentioned atomizer. Oil is admitted to the
apparatus by opening the regulating cock d. By unscrewing the cape of the said
apparatus the oil enters therein and is atomized by the steam jet and after mixing
with air is thrown into the fire tube t in the form of a fine spray, which is ignited
by a torch. The flow of oil can be regulated by the cap e, also by the regulating
cock d. The nut f with handles is used to hold cap e in any desired position, when
screwed up firmly against it, and also prevents oil from flowing back through the
threading of the cap, as the nut is arranged to receive a packing ring, which
tightens the threading of the cap, when the nut is screwed up against it. To the
apparatus is also attached a needle g with a fine point for the purpose of being
able to clean the fine steam channel of the apparatus instantly by simply pushing
the needle through it by the wooden handle h attached to it. The fine point of
the needle will remove any obstructions that may accumulate occasionally in the
steam passage. Before the steam enters the auxiliary steam chamber it passes the
reducing valve C. The purpose of the same is to keep an even steam pressure in
the auxiliary steam chamber that supplies the steam to the atomizers at any
desired pressure below boiler pressure. This reducing valve consists of a
membrane i on which steam pressure is counteracted by a spiral spring k, which
can be set and regulated by the nut l. To the membrane is attached the lengthened
valve stem m, which is made of two parts, one screwed into the other for the
reason of being able to give it the required length, in order to have the valve
properly act upon the valve seat n. The auxiliary steam chamber also separates
This
steam from any water and is freed from condensed water by the valve o.
condensed water is used to heat the oil, before it is atomized. The condensed
water enters the oil heating apparatus p through which the oil pipe q is led.
By heating the oil in the said manner, a more complete combustion of the same
is effected and a constant burning flame can be easily maintained, without the
_necessity of applying a constant burning torch.

1, JOHN LEE OSBORN, of Millbay Engineering Works, Millbay Pier, Plymouth,
in the County of Devon, (a communication to me from abroad by Carl Neuhaus,
of XVII Mazsseugasse 15 Vienna, in the Empire of Austria,) 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:-
α,
which
This invention relates to burning oil for steam boilers and the like. In the
drawings left with the Provisional Specification, the complete arrangement of an
oil burning apparatus is shown. Steam to the atomizer A is taken from the
auxiliary steamn chamber and separator B by opening the steam valve
causes the steam to blow through the fine opening c of the above mentioned
atomizer. Oil is admitted to the apparatus by opening the regulating cock d.
By unscrewing the cape of the said apparatus the oil enters therein and is
atomized by the steam jet and after mixing with air is thrown into the fire tube t
in the form of a fine spray, which is ignited by a torch. The flow of oil can be
regulated by the cap e, also by the regulating cock d. The nut with handles is
used to hold cap e in any desired position, when screwed up firmly against it, and
also prevents oil from flowing back through the threading of the cap, as the nut is
arranged to receive a packing ring, which tightens the threading of the cap, when
the nut is screwed up against it. To the apparatus is also attached a needle g with
a fine point for the purpose of being able to clean the fine steam channel of the
apparatus instantly by simply pushing the needle through it by the wooden
handle attached to it. The fine point of the needle will remove any obstructions
that may accumulate occasionally in the steam passage.
Before the steam enters
the auxiliary steam chamber it passes the reducing valve C. The purpose of the
same is to keep an even steain pressure in the auxiliary steam chamber that
supplies the steam to the atomizers at any desired pressure below boiler pressure.
This reducing valve consists of a membrane i on which steam pressure is counter-
acted by a spiral spring k, which can be set and regulated by the nut 1. To the
membrane is attached the lengthened valve stem m, which is made of two parts,
one screwed into the other for the reason of being able to give it the required
length, in order to have the valve properly act upon the valve seat n. The
auxiliary steam chamber also separates steam from any water and is freed from
condensed water by the valve o. This condensed water is used to heat the oil,
before it is atomized. The condensed water enters the oil heating apparatus p
through which the oil pipe 9 is led. By heating the oil in the said manner, a more
complete combustion of the same is effected and a constant burning flame can be
easily maintained, without the necessity of applying a constant burning torch.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The combination with an apparatus for burning liquid fuel of means for
admitting steam at a constant pressure whatever may be the boiler pressure
substantially as described.
2. The combination with an apparatus for burning liquid fuel of a chamber for
separating water from the steam substantially as described.
3. The nut for securing the cap and preventing the escape of the liquid fuel
substantially as described.

page_text: 4. Heating the liquid fuel before it is sprayed substantially as described.
5. Apparatus for burning liquid fuel substantially as described and shown in the
drawings.
