PROVISIONAL SPECIFICATION.
Improvements in Vapour Burners for Cooking Stoves.
I ARVID BÖHLMARK, Manufacturer of Högbergsgatan 21, Stockholm in the
Kingdom of Sweden do hereby declare the nature of this invention to be as
follows:-
:-
My invention has for its object an arrangement on such vapour burners for
cooking stoves in which the petroleum during its passage to the opening of the
burner is heated and transformed into gas by the heat from the burning flame.
In earlier constructions of burners according to this idea, the burner has been
made of a pipe curved in several vertical spiral windings the two ends com-
municating with the petroleum vessel. On the lower part of the central spiral
winding the opening for the burner was provided with the mouth turned upwards,
whereby the upper portions of the spiral windings were heated and the petroleum
flowing through thein was transformed into gas.
My arrangement consists in an improvement in burners of the class just mentioned
whereby they are made easier to clean and to rid from the tarry products of
distillation which settle ou the spirals. The burner is shown in the accompanying
drawing, where Fig. 1 is a side elevation and Fig. 2 a plan view of it.
As, shown, the burner comprises a spirally wound pipe both ends of which
communicate with the petroleum vessel the upper part of which is shown in the
drawing and indicated by the reference letter a. The lower central part of the
spiral wound pipe here consists of a straight pipe to the centre of which
the burner cape is attached in such manner that the mouth is turned upwards.
This straight pipe b is open in the one end and there provided with a gas-tight
screw plug d. The other end may also be arranged in the same manner.
By this arrangement the burner cap and the portion of the pipe next to it may
be easily and comfortably cleaned by loosening the screw d. The upper portions of
the spiral windings are somewhat turned out and curved in bow form in order partly
to provide a suitable heating of those portions, partly to make the burner cap more
easily accessible from above so as to be able easily to screw it off and on by means
of a key. The arrows in the drawing show the direction of motion of the petroleum
and petroleum vapours. A flame spreader f is shown in dotted lines fixed to the
upper portion of the burner.

page_text: In earlier constructions of burners according to this idea, the burner has been
nade of a pipe curved in several vertical spiral windings, the two ends com-
municating with the petroleum vessel. On the lower part of the central spiral
winding the opening for the burner was provided, with the mouth turned upwards,
whereby the upper portions of the spiral windings were heated and the petroleum
flowing through them was transformed into gas.
My arrangement consists of an improvement in burners of the class just
mentioned, whereby they are made easier to clean and to rid from the tarry
products of distillation which settle on the spirals.
The burner is shown in the drawing filed with my Provisional Specification,
where Fig. 1 is a side elevation and Fig. 2 a plan view of it. As shown, the
burner comprises a spirally wound pipe, both ends of which communicate with the
petroleum vessel, the upper part of which is shown in the drawing and indicated by
the reference letter a. The lower, central part of the spiral wound pipe here cou-
sists in a straight pipe b to the centre of which the burner cap c is attached in such
manner that the mouth is turned upwards. This straight pipe b is open in the one
end and there provided with a gas-tight screw plug d. The other end may also be
arranged in the same manner.
By this arrangement the burner cap and the portion of the pipe next to it may
be easily and comfortably cleaned by loosening the screw d. The upper portions
of the spiral windings are somewhat turned out and curved in bow-form in order
partly to provide a suitable heating of those portions, partly to make the burner
cap more easily accessible from above so as to be able easily to screw it on and off
by means of a key. The arrows in the drawing show the direction of motion of the
petroleum and the petroleum-vapours. A flame spreader f is shown in dotted lines
fixed to the upper portion of the burner.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
⚫ In vapour burners for cooking stoves composed of a spirally wound pipe, both
ends of which communicate with the petroleum vessel, and in which the petroleum
is transformed into gas before it issues through the opening of the burner applied to
the lower portion of the pipe, by means of the heat from the flame passing over the
upper portions of the pipe, the construction whereby the portion of the pipe next
to the opening of the burner consists of a straight pipe 6 the one or both ends of
which are closed by means of screws so that the pipe by loosening the screws may
be easy to clean.
