Engineer do hereby declare the nature of this invention for "IMPROVEMENTS IN
APPARATUS FOR BURNING LIQUID HYDROCARBONS" and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :—
In the accompanying drawings Figure 1 is a side elevation of this invention as
applied to a steam boiler.
Figure 2 is a central longitudinal section of the same.
Figure 3 is a section through the steam regulator.
Figure 4 is a side view of the same.
A is the boiler, or steam generator, of any ordinary or preferred form B is the
steam dome thereof C the pressure regulator, D the steam pipe carrying steam from
the boiler to the automizer E, G the tank for liquid fuel and F the combustion-
tube.
The boiler and combustion tube are enclosed within and supported by a suitable
casing.
The reservoir G for holding the liquid fuel, is provided with an opening a closed
by a screw cap or plug for the purpose of introducing the liquid fuel, which is
preferably a refined petroleum of the quality ordinarily employed in lamps,
although cheaper grades may be employed. A small opening may also be made in
the upper part of the reservoir to admit air.
From tho reservoir G the liquid fuel is drawn upward through the pipe or
conduit which at its upper end terminates in an orifice arranged in suitable
relation with the steam jet c thereby forming an injection or atomizer E by which
the sprayed oil is directed through the combustion tube F in which it burns to
produce the heat for generating steam in the boiler A. The steam jet c receives
steam from the boiler through the steam supply pipe D, being provided with a
valve d, or other suitable device for controlling the supply of steam to the jet. It
is preferred to use a combustion tube as shown in the drawings although its use is
not essential to the practical working of this invention. If used the inner end of
the combustion tube may be directed upward so as to turn the flame formed by the
sprayed oil against the lower surface of the boiler.

page_text: In order to provide for the regulation of the steam pressure in the boiler the
steam regulator C is employed it controls the supply of steam to the atomizer.
The regulator consists of a flexible diaphragm H. Figures 3 and 4 arranged in
connection with a valve so as to reduce or cut off the steam when the pressure in
the boiler becomes too great. The diaphragm H forms one side of a chamber into
which the steam is admitted through a pipe communicating with the boiler or the
steam dome. The diaphragm is provided with a boss e into which the stem of the
valve is screwed. The head of the valve is fitted to a suitable valve seat
Figure 3 and it operates when the diaphragm H is pressed outward as represented
by the dotted lines by the steam in the chamber to diminish or entirely cut off the
supply of steam to the atomizer. The amount of pressure which will be required
to accomplish this result may be regulated by screwing the valve i in or out of the
boss c.
The practical effect of the regulator is that if the pressure in the boiler
rises above any given point at which the valve is set the supply of steam to the
atomizer is entirely cut off and the fire goes out. It will be noticed that if the
water should be entirely evaporated from the boiler, there will be no more steam
to supply the atomizer and the fire in this case also will be extinguished.
Provision is thus made for ensuring entire safety under any circumstances which
may arise.
In starting an engine provided with this regulator a pressure is produced in the
boiler by means of an air pump or if the engine be small by turning it backwards
the air pressure serving to work the atomizer.
In the accompanying drawings a construction is shown in which the steam
passes through the regulator but this arrangement is not essential to the operation
of this invention as the diaphragm may be employed in various different ways to
control the supply of steam to the atomizer without departing from the principle
of the part of said invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed declare that what
I claim is:
:
1 In an apparatus for burning hydrocarbons the combination of an oil reservoir (
a steam oil atomizing jet c an oil conduit b a steam supply pipe D and a steam
regulator C operating to vary or cut off the supply of steain from the boiler to the
atomizer substantially as and for the purposes set forth.
2. In an apparatus for burning hydrocarbons the combination of an oil reservoir G
a steam oil atomizing jet can oil conduit b and a steam supply regulator C through
which the steam passes on its way from the boiler to the atomizer substantially as
described.
