Improved Incandescence Gas Burner.
I, ALEXANDRE MURINICK, of No. 47, Mochovaia, St. Petersburg, Russian Empire,
Merchant, 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 new burner for incandescence gas lighting
which possesses the following distinguishing points:
1. It is independent of fluctuations of the gas pressure as the pressure in the
burner itself can be regulated at will. The arrangement moreover is such that
the pressure waste is reduced to a minimum which has not been so completely
attained in any other system hitherto employed.
2. By means of the novel construction of this burner there is attained as com-
plete as possible a mixture of the gas and its requisite quantity of atmospheric
air.
3. The burner is arranged in such a way that the part supporting the incan-
descent mantle forms a spring so as to absorb any shocks or jars.
4. The apparatus which is provided with the inlet nozzle hereinafter described
is separated by a perforated plate from the support of the incandescence mantle
so as to break the force of the draught entering sideways.
It may be remarked generally that the regulation of ordinary Welsbach and
other burners is very imperfect in consequence of the frequent change in the
pressure of gas, while the outlets remain unaltered or can only be altered by
mechanical means. As mentioned at the beginning, the pressure of gas in the
present new burner can be regulated immediately and with the greatest accuracy.
One constructional form of a burner of this kind is illustrated in the accom-
panying drawing:
Figure 1 is a longitudinal section.
Figure 2 the arrangement of the inlet nozzle on a larger scale.
Figure 3 is a view from above of Figure 2.
The body a preferably of the shape shewn has at its top the perforated cap b.
This cap is supported by a small tube c which is slit several times at the top so
that by means of the screw nut d placed on this tube the magnesite or refractory
support e holding the incandescent mantle can be firmly held. The gallery f for
the chimney is suitably fixed in any preferred manner.
The body a is attached by means of bayonet catches or in any other convenient
manner to a ring g which is provided below with a perforated plates and is con-
nected at several points to a metal dish i by means of springs h h. The dish i has
several air holes and a support n which is screwed on and made fast to the dish i
by means of the nuts m. This support is provided with inside threadings as shewn
in Fig. 2, so that the nozzle o can be screwed into the said support n. This nozzle
has several vertical apertures through which the gas escapes.
As is obvious from the preceding description, the end of this nozzle is closed.
It can, moreover, be screwed into or out of the circular aperture p at the top of the
support n so that the free area of this aperture can be made larger or smaller as
TD-0-7-7-

page_text: desired. In consequence of the gas escaping vertically through the holes the gas
current maintains its maximum force as it is nowhere checked. It has moreover
this advantage, that as the gas escapes in the form of a ring the inner and outer
surfaces of the hollow cylinder of gas thus formed have considerably more chance
of mingling with the surrounding atmosphere than in other systems already
known. The nozzle o is moreover, as can be seen in Fig. 2. internally threaded
so that the whole burner can be screwed by means thereof on to a gas pipe A of any
kind. The method of operation of the device is as follows:-
If, for instance, the pressure in the gas pipe is very great, the flame will burn
in consequence above the incandescent mantle. In order to obviate this, the
screw 2 is loosened and the support screwed down!' The aperture p becomes
smaller in consequence and the escape of gas diminishes. This adjustment of the
nozzle can be fixed in this position by means of the screw 2 so that the flame burns
uniformly. If, on the contrary the pressure of gas is too low, then the support n
is screwed upwards which has the contrary effect and the aperture p becomes
larger. It should be noted that after the exit of the gas through the aperture p
there is a primary intimate mingling with air in the dish which is further con-
siderably augmented in the lower part of the body a. The mixture then (as
indicated by the arrows) arrives together at the incandescent mantle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is:
1. The improved incandescence gas burner comprising the body (a) supporting
the mantle, said body formed preferably semicircular beneath and conical above;
attached by a bayonet or the like fastening to a ring such as (9), supported on
springs by a dish (i) in such a manner as to prevent any jar of the mantle, the
said ring (9) having the perforated or woven partition (s) arranged to prevent side
draughts, all substantially as described.
2. In an incandescence gas burner of the type set forth in Claim 1 an inlet
nozzle for the gas in the form of a cone which can be screwed up or down and
thereby can increase or diminish the gas in the gas inlet, the said gas passing
through vertical holes such as (e) in the support ("), thus flowing unobstructed
and with full force through the annular opening (p) substantially as described and
shewn.
3. In an incandescence gas burner of the type set forth in Claim 1, the method
of supporting the magnesite or refractory support for the mantle consisting in the
centrally located tube (c) arranged to hold the support (e) exactly in the centre by
means of the screw nut (d), said device being easily tightened or released.
4. The improved incandescence gas burner constructed and operating sub-
stantially as described and illustrated in the accompanying drawings.
