Improvements in or relating to Gas Burners
We EDWARD PHILIP WILLIAMS, Gas Engineer, and WALTER JOHN THOMAS,
Engineer, both of 48 Osnaburgh Street, London in the county of Middlesex, 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:
This invention relates to certain improvements in and connected with gas lighting
or burning apparatus of the kind wherein gas is led into a closed receiver containing
or carrying externally the burner or burners, as, for example, in "sunburners" and
other lamps: Where such an arrangement is used, the heat generated by combustion
is so intense as to carbonise gas before it arrives at the burners, and the carbonaceous
deposits formed, being of a gritty or powdery nature, are apt to choke up the burner
orifices and destroy the efficiency of the lamp; moreover by the intense heat the
burners themselves as usually constructed are rapidly destroyed.
The object of the present invention is to obviate these defects, and the improve-
ments consist, first, in applying to the closed gas receiver, means for precluding the
access of deposits to the burner orifices, and secondly, in constructing a burner for
use with such apparatus, adapted to withstand the action of the said intense
heat.
We will now describe our invention more fully with reference to the accompanying
drawings, which represent its application to "sunburner" having external burners,
though it will be understood that the means described for preventing choking of
the orifices may be applied also to certain closed lamps having internal burners.
Figures 1 and 2 are sectional elevations of our apparatus, and similar letters of
reference refer to similar parts.
a is a closed receiver of any suitable form and material, and bb are the orifices.
According to the usual construction gas, is led to the receiver by a pipe p which does
not extend into the receiver, but terminates at or about its interior surface, thus
carbonaceous deposits lodged in the receiver, especially under pressure, may be easily
blown into and choke the burner orifices 6: By our improvement we extend the.
pipe p as shown at p¹ for a suitable distance into the receiver, and beneath its open
end we dispose a set or sets of inclined surfaces, but preferably a truncated cone or

page_text: pyramid inverted as shown at c c¹, forming the separate chamber a² at the lower part
of the receiver a. In some cases we may use an additional set of inclined surfaces or
part of a cone or pyramid (figure 2). The parts c c¹ are made of thin metal or
material adapted to with stand intense heat, and may be fixed with a flange between
the two parts of the receiver as illustrated, or in any convenient manner. At the base
of the receiver, in chamber a², we provide a screw plug 8. All deposits formed are
blown and pass through the opening c¹ into chamber a³, whence they cannot return
or be blown back to the burner orifices 6 b, and may be removed when required by
the screw plug 8.
The construction of burner we use with the apparatus described is illustrated in
figures 3 and 4. It consists of a wrought iron casing w, coned and screwed externally
at one end as usual; concentrically within the casing we fix, with red lead or other-
wise, a long hollow burner b, of steatite or soapstone, and pierced as usual with gas
escape orifice or orifices. We have found that by this construction the steatite is not
liable to come out of the wrought iron when highly heated, as is the case with cast
iron or brass casings.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we caim is:—
1. The application to a closed gas receiver containing or carrying a burner or
burners, of means, such as are hereinbefore described, for precluding the access
of deposits to the burner orifices, substantially as set forth in reference to figures 1
and 2.
2. In gas lighting or burning apparatus having a gas receiver of the type
hereinbefore described, a burner constructed as specified and illustrated in figures 3
and 4.
3. In gas lighting or burning apparatus, the combination with a receiver a,
extension p¹, parts cc, and plug 8, of burners 6 constructed and arranged as set
forth.
