PROVISIONAL SPECIFICATION.
Improvements in Gas Burners and Appliances for Heating, Lighting,
and Ventilating Purposes.
WILLIAM WELCH 36 Saint George's Square Portsmouth in the County of Hants
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
This invention consists in producing a more efficient and safe process in burning
gasses, realizing greater heating, and lighting energy, and preventing noxious and
deleterious fumes arrising from the products of combustion, and obviating all dangers
from back lighting as with atmospheric burners.
In order that my invention may be practically understood, the burners and
appliances are made of any size, shape, or surface, for universal use either spherical,
cylindrical, horizontal, conical, or other figure enclosed within metal casings of plain
or perforated surfaces, at the entry of the gas supply into the chambers, a regulator
stop tap or valve is attached leading into a central expansion chamber, around this
chamber is enveloped finely perforated layers of metallic or mineral substances, of
similar or dissimilar chemical character, the gasses entering are freely circulated, and
passed through this medium into a second expansion and superheating combustion
chamber, the exterior of this chamber is enveloped with a metallic or refractory
mineral casing or shell of similar or dissimilar chemical character through this surface
entering into the superbeating chamber finely or coarse insertions are perforated
agreeably to the use intended and forming the atmospheric burning surfaces.
When the burners are used enclosed for heating, ventilating, and thermo-electric
purposes, they are encased within perforated metal casings or cylinders, carried to
any required height above the surface of the burner, and where desireable connected
with the outer atmosphere, the interior casing receiving the heated gasseous products
of combustion, and producing a powerful exhaust circulating current for ventilating
purposes and drawing off through the perforated chimneys or casings all deleterious
vapours and gasses, causing perfect ventilation for buildings, rooms and spaces of
any description the perforated chimneys or pipes are attached to any heating and
ventilating apparatus or pipes, ordinary or gas stoves.

Improvements in Gas Burners and Appliances for Heating, Lighting,
and Ventilating Purposes.
WILLIAM WELCH of 36 Saint George's Square Portsmouth in the County of Hants,
Civil Engineer, 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 consists in producing a more efficient and safe process in burning

page_text: gasses for illuminant and non-illuminant purposes, realizing greater heating and
lighting energy, and preventing noxious and deleterious fumes arrising from the
products of combustion, and obviating all dangers from return or back-lighting as
with atmospheric burners.
In order that my invention may be practically understood is.-The burners
and appliances are constructed of any size shape, or surface and adapted for universal
use, either spherical, horizontal, cylindrical, conical, vertical, or other figure, enclosed
or partialy enclosed within metal casings of perforated or plain surfaces.
At the entry of the gas supply into the chambers of the burners a regulator
stop, tap, or valve is provided for regulating the amount of gas, and leading into a
central expansion chamber, as on plan marked A. Around or over this chamber
is envelope A made of perforated material in order to act as a check or regulator
to the expanded gas.
The gasses entering are freely circulated and passed through this medium into a
second expansion, superheating combustion chamber, B. The exterior of this chamber
is enveloped with a refractory mineral or metallic casing, or shell of dissimilar or
similar character. Through this surface entering into the superheating combustion
chamber, finely or coarse insertions are perforated agreeably to the uses for which
the burners are intended, and forming the atmospheric burning surfaces.
When the burners are used for heating, ventilating and germicide" purposes
they are encased within perforated metal, concentric casings, cylinders, or chimneys C,
carried to any height required above the surface of the burners and where desireable
connected with the outer atmosphere, the casings, cylinders and chimneys receiving the
heated gaseous products of combustion, and producing a powerful exhaust circulating
hot current, for "germicide" and ventilating purposes, and drawing off through
the perforated casings or chimneys all deleterious vapours and gasses and producing
perfect ventilation for buildings, rooms, workshops sewers, and spaces of any
descriptions. The perforated casings, cylinders, and chimneys are attached to any
heating and ventilating apparatus or pipes, and ordinary stoves or gas burning
appliance.
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
The formation, construction, and application of gas burners and appliances, as
substantialy described.
