Improvements in Petroleum Burners, Petroleum Stoves, Soldering
Lamps, and the like.
I, CARL JOHAN FREDRIK MALCOLM LILLIEHOSк of Brahegstan 25, Stockholm,
in the Kingdom of Sweden, Civil Engineer 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:-
The present invention has for its object to improve petroleum burners or stoves,
soldering lamps and the like to avoid the following inconveniences, which are apt
to occur with the petroleum stoves hitherto in use. Such inconveniences are that
it is difficult to light said stoves without having previously imparted to the burner
a sufficiently high temperature by heating it with spirit or benzine to thus completely
gasify the petroleum; that further it is almost impossible to free the burners of the
carbon which accumulates in large quantities in the interior of said burners, and
which causes the latter to become worn out.
The annexed drawings represent three forms of construction of the improved
petroleum burner or stove. They are provided either with one burner (Fig. 4) or
with two burners (Figs. 1-3). In the latter case one burner serves for lighting
while the other is used for gasifying purposes. Figs. 1-3 show vertical sections
of the oil tubes (a'-a³) of two petroleum stoves, Fig. 4 being a modification.
In the drawings only one part of the petroleum reservoir (Fig. 2 A.) is illustrated
which is as usually, provided with an air pump B and a safety valve C.
On
From the reservoir A run two tubes one b¹ from its upper part, the other a' from
the bottom, to a cock D or any equivalent attachment, so that either air and oil
may be supplied to the burner E, or only oil to a so called main burner F.
turning the cock D as may be seen from Figs. 1 and 2, the air and the oil pass
through the cock body (the tubes a 62) to a lighting burner E, through the
tubes a a, 63 and on turning for instance said cock through an angle of 90°,
nothing but oil will pass to the main burner F through the tubes a', a², e.
l
The burner E consists of two parts uz.: a lower part n with two passages or
tubes (-, a-a³,) for air and oil further of an upper part with the mouth d
said parts being so arranged as to enclose a space c which freely communicates with
the two passages or tubes a¹-a³, b'—b³.
The main burner F is composed of a covering plate T formed of two parts & s
which are so arranged as to enclose a space v that has communication with two
tubes e el that is to say a small tube e with mouth g and screw h for purposes of
cleaning, and a larger tube e' which communicates with the petroleum reservoir A.
The upper part of the burner is surrounded by a shell or casing for protection
against draught.
When the burner is to be lit air is introduced into the reservoir A by means of a
strong air pump B to thus impart a slight pressure within said reservoir whereupon
the cock D is adjusted as shown in Figs. 1 and 2 to cause oil and air actuated by
the pressure to ascend through the tubes a'-a, 61-63 up to the lighting burner É
and there (at c) to intermingle, whereby the oil in its divided state is thrown out
and so permits of being easily lit, and burned with strong generation of heat. As
soon as the main burner F together with the tube el pertaining to it, has been
sufficiently heated, the cock D is turned, whereby the oil may run in the tube e¹ to
the main burner F wherefrom after gasification it emanates through the opening g.
[P

page_text: Instead of a cock D for opening and closing the air and oil conduits so that only
oil is supplied to the main burner F, any other suitable arrangement may be
employed such for instance as illustrated in Fig. 3 in which the closing of the
burners E, is effected by a valve D₁ while another valve D2 opens the oil conduit
to the main burner. The burner shown in Fig. 3 differs from the last described
inasmuch as the main burner F is provided with a separated oil conduit. The
lighting burner E has also in this case an air and oil conduit 6'-a'—a³ which
communicates with a space c with mouth d.
The burner represented in Fig. 4 differs from that in Fig. 3 in the fact that
the oil is not directly led over the flame to be gasified this gasification being
accomplished by surrounding the burner with a hood H which latter after being
heated transfers its heat to the burner G.
The burner G consists of two parts viz.: a lower part n with two conduits or
tubes for air b¹-63 and for oil a-a respectively, further of an upper part with
outlet d said parts being so arranged as to enclose a space c in which the air and
the oil intermingle
On lighting the burner the cock is in such position that oil and air are caused to
ascend through their respective tubes a¹-a, b-b³, from the reservoir A to the
burner G, whereby the oil is atomized by the air draught. The hood H and the
burner G having been sufficiently heated so that the oil is exposed to gasification,
the air inlet is closed by turning the cock D, for instance through an angle of 90°,
so that only oil may penetrate through the tube a³ into the burner G, from which
the oil after gasification is carried off only through the ducts at and d.
Heated
air is supplied to the flame through the openings o in order to facilitate the process
of burning.
The regulation of the flame may either be accomplished by means of cock D or
the safety valve c.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is―
1. A construction of petroleum burners petroleum stoves, soldering lamps and
the like characterized by oil and air being previously supplied to the burner by
means of air pressure when the burner is to be lit to thus cause the oil to be atomized
and admit of being easily lit said oil being then in consequence of the heating of
the burner exposed to gasification.
2. In the burner described the construction of the burner of two parts the lower
onen being provided with the air conduit or pipe 6-³ the upper one with the
oil conduit or pipe aa the latter having at the same time an opening for the
outlet of the oil intermingled with the air in the space e between the said two parts.
3. In combination with the arrangement described a cock or any other suitable
attachment for closing the air and oil condunts so that according to the position
of said cock or the like either air and oil simultaneously or only oil may pass from
the reservoir into the burner.
4. In petroleum stoves soldering lamps and the like constructed to require
compressed air for passing oil and air from the reservoir into the burner, the
construction of the lighting burners E, G of two parts I, n, the lower one n of
which is fitted with air conduit b¹-63 and oil conduit a'-a³ the upper part / being
provided with an outlet opening d said parts being at the same time so arranged
that they enclose a space C which freely communicates with said tube
conduits ¹³, a-u³ for the purpose of facilitating the lighting of the oil
atomized by the air current.
5. In petroleum stoves, soldering lamps and the like the combination of the
reservoir A with a lighting burner E. G said burner being provided with a shorter
tube conduit for the air and with a longer conduit a'-a³ for the oil said
tube conduits being moreover so arranged that they communicate with a space c
and are provided with a cock D or valve D¹ D or any other suitable attachment

page_text: whereby oil and air may be caused to ascend simultaneously from the reservoir A
up to the lighting burner E. G, or only oil pass to said burner or to the main
burner F respectively.
