COMPLETE SPECIFICATION.
An Improved Method of Increasing the Illuminating Power of
Flames.
I, LASSLO CHANDOR of St. Petersburg in the Russian Empire, No. 44
Furstadskaia Str. Gentleman, do hereby declare the nature of my said inven-
tion and the manner, in which the same is to be performed, to be particularly
described in and by the following statement :-
My invention relates to an improved method of increasing the illuminating
power of various flames from mineral or vegetable oils independently of the special
construction of the lamps.
The invention consists mainly therein that a body composed of a specially
prepared mass or composition is located in the immediate vicinity of the flame
or flames of hydro carbon or oil burners so that the illuminating power is increased
and a perfect combustion of the material employed attained by means of the incan-
descency of the abovenamed body and the increased draught and air feed and
relates to a characteristic improvement in the manufacture of the incandescent
body employed by me which is preferably of cylindrical form.
The main ingredient of the new mass or composition is asbestos which is
previously heated to glow heat and then treated with acctate of magnesia or its
equivalent gum tragacanth or other appropriate gum being then added to the mass.
The incandescent body is now molded in desired size and form from the above-
named mass and as soon as the said composition is dry the same can be used for
the given purpose.
The employment of magnesia and gum tragacanth is not the characteristic
feature but the application of asbestos whereas magnesia and gum tragacanth
have proved to be useful ingredients although, I wish it to be understood that
other silicates and gums can be used to advantage. The application of my inven-
tion is represented in the accompanying drawing in which
Fig. 1. represents a petroleum burner with my improved incandescent body
partly in elevation and partly in vertical section.
Figure 2. is a like representation of a duplex burner with two flat wicks.
The incandescent body a of cylindrical or other appropriate form and composed
of the improved asbestos mass, is as represented by Fig. 1 and 2 so fixed in
upright or vertical position to the burner of the lamp that the flame from the wick
or burner tip impinges against and remains in contact with the said incandescent
body it being preferable to employ the ordinary intended chimneys for deflecting
the flame towards the middle of the chimney. The incandescent body can be
rigidly attached to the burner in appropriate manner. In Fig. 1 the said incan-
descent body a is shown fixed to a holding device consisting of a sheet metal cross b
with shell c or as shown in Fig. 2 the incandescent body is provided with a boring
by means of which the said incandescent body can be placed on a suitable pin or
peg or the same can be fixed in any other appropriate manner.
By means of the position of the incandescent body in the direction of the internal
draught in combination with the indented portion of the cylinder an effectful
deflecting of the flame and the air into a suitable space surrounding the incan-
descent body, so that a perfect combustion and increased brilliancy of the flame,
is attained.
The intensive combustion which is attained in this manner serves to fully utilize
the illuminating power of the flame on the one hand, whilst on the other hand the
body a is caused to become incandescent so that the incandescence will not only
increase the illuminating power of the lamp but produce a perfect combustion of
the hydro carbon, oil, or other fluid.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and the manner in which the same is to be performed I declare, that what I
claim is :
Increasing the illuminating power of flames by means of an incandescent body a
arranged vertically in the burner and consisting essentially of asbestos with an
addition of acetate of magnesia or other appropriate salt and gum tragacanth or
other suitable gum, substantially as described in the foregoing Specification and
shown in the drawing.
