An Improved Burner for Cooking Stoves.
I, JOHAN VICTOR SVENSON of, 44 Kungsgatan, Stockholm, in the Kingdom of
Sweden, Manufacturer; 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 object of this invention is to provide an improved burner for cooking
stoves, which is constructed in such a manner that a portion of the flame is con-
ducted downward so as to give off its heat partly to the evaporated oil before it
escapes through the nozzle of the burner, and partly to the oil reservoir, thus
imparting to the vapours formed in the latter a pressure, sufficient to force the oil
up in the burner, without the use of a pump, and by this means materially
reducing the cost of manufacture of the stove.
In the accompanying drawing
Figure 1 represents a front elevation of a cooking stove, provided with my
improved burner,
Figure 2 is a vertical section through the lower portion of the burner, illustrating
the construction of the regulating valve, and
Figure 3 is a plan view of the said burner.
The burner is composed of a piece a, provided with a discharge passage for the
vapour and arranged in such a manner that it may be secured to a pipe b leading
from the oil reservoir. Around the said piece a is placed a suitable number of
approximately vertical tubes e, open at both ends and with their upper ends situated
in a disk d with a central opening; above the upper outlets of the tubes the usual
diske for spreading the flame is placed resting loosely for instance on the lugs f
of the disk d.
By this arrangement a portion of the flame that strikes against the spreading
disk is deflected into the tubes c and directed through the latter towards the piece a,
the evaporator, which is thus highly heated. The combustion will consequently
be very intense and the efficiency of the stove increased. Directing the flame
downward will, of course, effect a material rise in the temperature and pressure in
the reservoir. As this increase in temperature depends on the distance of the
burner above the reservoir, all danger of explosion can be avoided by making this
distance sufficiently great, while at the same time it is possible to heat the
reservoir to such an extent that the pressure required is generated in the
reservoir.
The pressure is regulated by means of a valve g inserted in the piece a and
adjustable from the outside, this valve enabling the lower aperture of the vertical
discharge passage in the piece a to be opened more or less, as may be required;
the valve being situated in the upper part of a second passage leading straight
down to the pipe 6 protruding from the reservoir.
The passages are arranged as described with the object of facilitating the
cleansing of the same.
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 :-
An improved burner for cooking stoves, consisting of a piece a, the evaporator,

tubes c open at both ends, the lower apertures of said tubes being arranged around
the piece a while their upper orifices open in a disk d provided with a central
opening, and a common, spreading disk e for the flame, arranged directly above the
said disk d all with the object that a portion of the flame striking against the
spreading-disk may be deflected into the tubes and directed by them towards
the evaporator a, thereby heating it and transmitting a portion of the heat to the
oil reservoir.
