Improvements in Burners for the use of Gas and other Inflammable
Vapours.
I, WILLIAM WELCH 36 St. Georges 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 :-
The object of my Invention is the construction, and equipment of Gas Burners, for
producing a mere perfect combustion-and incandescence-in the use of coal-water-
and oil gasses-and in destroying the noxious and deleterious effluvium arrising in
the burning thereof.
In order that my Invention may be fully and practically understood viz. :-
I form or construct the Burners through which the gasses pass for ignition, as
follows a case-box-or shell-or lining, of any required shape or dimension, to suit
the position and use-leaving the part to form the surface of ignition open as shewn
on drawing-A-the casing may be of metal-porcelain or other heat proof material.
Through the casing-leading within the interior a pipe-joint-or union is inserted
for connecting the gas supply-in which a tap-or stop valve is placed-as shewn
on drawing B.
The inside of the case-or box is lined with a coating of adhesive fire resisting
composition or non-conducting substance-as shewn on drawing-C. Immediately
over the supply pipe, entering the Burner, a finely perforated metallic plate, or
wire gauze, is fixed-covering the entire area-forming a chamber or space for the
expansion or distribution of the gas-as shewn on drawing D. Over this perforated
surface, a layer of any required thickness of loose-or agglutinated-granular-mineral
-or metallic substance of a similar-or dissimilar-character-are produced and
forming a finely- -or coarsely,cellulated-vaccuos, or porous filtering medium-
through which the gasses pass to the surface of ignition--as shewn on drawing E.
Over this is laid a covering--or thickness of fire-proof plastic cement composition---
from inch to 1 inch in thickness-thus sealing the filtering medium perfectly gas-
tight-a
-as shewn on drawing H-H. Through the plastic covering-finely-or coarsely
perforated holes are made into the porous medium.
Conformable with the amount of heating or illuminated surface required-and
forming the surface of ignition with the atmosphere-ordinary or improved
illuminated burners-may be inserted and fixed in the plastic covering in lieu of the
perforated holes as shewn on drawing at Land for large burning surfaces
perforated fire-tiles-or bricks may be used-and interspersed with metal protecting
ribs or bars-between the perforations-as at M-N-O-and for directing radiation
and reflexion-screening or conducting the flame-perforated or plain-metallic
mantlets are introduced around or over the surface of ignition.
To localize or confine the heat-and for greater incandescence the surface of
ignition is covered with fibrous asbestos or other similar substance-loosely
applied.
The Burners are used without or with the introduction of atmospheric air-and
are of any configuration or surface-and are used in any position-horizontal-vertical
angular-or inverted-as shewn on drawing at P-or in blocks or slabs of small
or large dimensions-as at M-N-O-on drawings-and are universally suitable
for all uses of illumination-and heating purposes-lamps-open or closed fire-places-
stoves-cooking ranges-ovens-furnaces &c., and can be used, and applied, to any
present constructed lamps or fire-places without alteration.

page_text: 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
1st. The construction of expansion chambers-or spaces-within the interior of the
Burners for increasing the volume of the gasses after entry from the supply pipe.
2nd. The filtration or purifying the gasses within the Burners by passing through
granular porous or vacuous medium of similar or dissimilar substances whereby
disintegration is attained, previous to passing to the surface of ignition-and
producing greater incandescence.
3rd. The super-heating the gas previous to coming in contact with the atmospheric
air by passing through the heated fire-proof or porcelain surfaces.
4th. Preventing the escape of noxious effluvium-by the expansion-filtration-and
superheating the surface of ignition-without being in contact with heated iron-or
metal pipes and surfaces.
