I CORNELIUS CRASTIN of 185 Hornsey Road, in the County of Middlesex, Engineer
do hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in or applicable to burners for consuming
oil or gas the improvements having for object to obtain a more perfect combustion
combined with steadiness and better shape of flame.
In carrying out my invention as applied to an oil lamp I apply what I term a
deflector above the ordinary deflector or air regulator or spreader of the lamp burner.
My additional deflector consists of a kind of box or chamber preferably perforated on
the under side and connected to a tube leading to the central air chamber of the
burner.
In some cases I employ two of my improved deflectors one placed above the other.

page_text: I, CORNELIUS CRASTIN, of 185, Hornsey Road, in the County of Middlesex,
Engineer, do hereby declare the nature of this invention and in what manner the
sanie is to be performed to be particularly described and ascertained in and by the
following statement :-
This invention relates to improvements in or applicable to burners for consuming
oil or gas the improvements having for object to obtain a more perfect combustion
combined with steadiness and better shape of flame.
In carrying out my invention as applied to oil lamps having a central air passage
for supplying air to the burner I apply what I term a deflector above the ordinary
deflector or air regulator or spreader of the lamp burner. My additional deflector
consists of a kind of box or chamber perforated on the underside and connected to a
tube leading to the central air passage of the burner.
My perforated box or deflector is equally applicable to gas burners more especially
to those of the Argand type whether such burners be provided with a deflector
or not.
In some cases I employ two of my improved deflectors one placed above the other.
In order to enable my invention to be fully understood I will proceed to describe
how it can be carried into practice by reference to the accompanying drawings
in which
Figure 1 is a vertical section of an oil-lamp burner with my improvements applied
thereto.
Figure 2 is an inverted sectional plan on the line A B of figure 1 serving to show
the underside of the deflector.
Figure 3 is a similar view to figure 1 but showing my improvements applied to a
gas-burner, a portion of the glass chimney of the same being also shown.
Similar letters in all the figures indicate similar parts.
Referring to figure 1 a is the wick-tube, 6 the wick, c the usual deflector, d the
central air passage and e the hood of the burner, all of which are of ordinary
construction.
fis my additional deflector which as shown in figures 1 and 2 consists of a kind of
box or chamber; 9, 9, 9 are the perforations on the underside of the box or chamber:
his the tube carrying the box or chamber as well as the usual deflector c, the said tube
leading to the central air passage d of the burner and forming a communication
between the latter and my additional deflector f.
The box or chamber forming the deflector fis preferably made of some refractory
material such as fire-clay, steatite, or porcelain, which will become highly heated by
contact with the flame of the lamp.
When the wick is lighted the flame is first deflected outwards by the usual
deflector c and passing upwards towards my additional deflector fit is fed with highly
heated air coming through the perforated bottom of the same, this current of air will

page_text: tend to keep the flame spread outwards somewhat in the shape represented in figure 1,
and the great heat emitted by the deflector f will burn up any carbon or smoke at the
edge of the flame and the edge will thereby be kept quite even.
Figure 3 illustrates my deflector f applied to an ordinary Argand gas burner which
is not already provided with a deflector.
In this case my deflector f the construction and purpose of which are the same as
that herein before described with reference to figures 1 and 2 is fitted to a tube h, in a
like manner, but the tube extends below the central air passage d of the burner
where it is advantageously formed with a trumpet mouth as shown; i is the usual
gallery and the glass chimney of the lamp.
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 combination with oil-lamp burners and gas-burners of a box or chamber
perforated on its underside and forming a kind of deflector in communication with the
central or other air-passage of the lamp or burner substantially as and for the purpose
herein before described with reference to the accompanying drawings.
2. The manufacture and use of the improved deflector hereinbefore described and
represented in the accompanying drawings.
