PROVISIONAL SPECIFICATION.
Method of Manufacturing Wickless Burners for Petroleum Stoves
and the like and Burners thus Produced
I, FERDINAND PETTERSON, of Handtverkaregatan 39, Stockholm, Sweden, Manu-
facturer do hereby declare the nature of this invention to be as follows.-
-
The present invention relates to a method of manufacturing such wickless
burners for petroleum-stoves (vapour-burners) as are constructed with a view to a
noiseless burning of the petroleum and the like, and burners thus produced.
In burners of the kind in question the vaporizer at the top of the burner has
heretofore been made of a tube bent in the shape of a 1ing and connected by
means of curved tubes on the one hand with the oil-reservoir, and on the other
hand with the nozzle, while between the tubes mentioned are placed two con-
centric tubes or funnels, between which the escaping petroleum-vapour is con-
duoted down-wards after having first flowed upwards through the inner tube.
According to this invention I manufacture the vaporizer of such a burner, by
bending the outer one of the two tubes or funnels mentioned outward and down-
ward so as to form an annular vaporizing passage
In the accompanying drawing a burner made according to this invention 18
shown
Figure 1 is a vertical section and
Figure 2 is a plan-view of the same.
Referring to the drawing a and b are the usual branched tubes and c is a fixed
flame former The inner one of the two concentric tubes d, f is attached to the
said flame former c in the usual manner The annular vaporizing passage gat
the top of the burner is, according to this invention, produced by bending the
upper end of the funnel f outward, and curving the same over (by spinning in a
lathe, drawing in a press, or like means), so that its edge comes close to the outer
side of the said funnel, to which it is subsequently soldered, or otherwise suit-
ably secured. The funnel is fastened closely to the tubes a and b, so that the
annular passage g is in communication with the tubes a and b The tube f is
provided with perforations f1 for the escape of the mixture of petroleum and
air The upper orifice of the tube f is closed by means of a cap h.

I, FERDINAND PETTERSON, of Handtverkaregatan 39, Stockholm, Sweden, Manu-
facturer, 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 relates to a method of manufacturing such wickless
burners for petroleum-stoves (vapour-burners) as are constructed with a view to a
noiseless burning of the petroleum and the like, and burners thus produced.
In burners of the kind in question the vaporizer at the top of the burner has
heretofore been made of a tube bent in the shape of a ring and connected by
means of curved tubes on the one hand with the oil reservoir, and on the other
hand with the nozzle, while between the tubes mentioned are placed two con-
centric tubes or funnels, between which the escaping petroleum vapour is con-
ducted downwards after having first flowed upwards through the inner tube.
According to this invention I manufacture the vaporizer of such a burner by
bending the outer one of the two tubes or funnels mentioned outward and down-
ward so as to form an annular vaporizing passage.
In the diawing filed with my Provisional Specification a burner made accord-
ing to this invention 18 shewn

Fig. 2 18 a plan-view of the same
Referring to the drawing, a and b are the usual branched tubes and c is a fixed
flame former The inner one of the two concentric tubes d, f is attached to the
said flame former c in the usual manner The annular vaporizing passage gat
the top of the burner is, according to this invention, produced by bending the
upper end of the funnel f outward, and curving the same over (by spinning in a

side of the said funnel, to which it is subsequently soldered, or otherwise suit-
ably secured. The funnel is fastened closely to the tubes a and b, so that the
annular passage g is in communication with the tubes a and b. The tube f is

air.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same 18 to be performed I declare that what I claim
18
-
1) The method of manufacturing the wickless vapour burners in which the
vaporizer is formed of an annular passage at the upper part of the burner and in
which two concentric tubes or funnels are located above the nozzle of the burner
for the purpose of conducting the mixture of vapour air upwards and downwards
before its final escape, which consists in bending the upper edge of the outer tube
or funnel by spinning in a lathe, drawing in a press or equivalent means, and
securing the same to the outer side of the funnel substantially as set forth.
2) The improved vapour burner constructed and operating substantially as
described with reference to the accompanying drawings
