PROVISIONAL SPECIFICATION.
Improvements in Means or Appliances for Exhausting and Con-
suming Foul Air or Gases from Sewers or other places containing
Foul Air or Gases and for Effecting Ventilation of the same,
applicable also for Heating Purposes.
I STEPHEN HOLMAN of 15 Great George Street in the City of Westminster Engineer
do hereby declare the nature of this invention to be as follows:-
My invention relates more particularly to apparatus of the class described in the
Specification of my Letters Patent No. 15519 of 1887.
The principal object of my present invention is to provide in connection with the
burner used in the said apparatus means whereby a much more perfect combustion of
the gas is ensured and the flame is protected from being accidentally extinguished.
According to my present invention I place on the top or at the nozzle of the
atmospheric burner a hollow chamber into which the gas and air are received before
combustion, the said gas and air leaving the said chamber by a slot surrounding the
said chamber about midway thereof, at which slot the flame issues.
The chamber is so shaped preferably by curving or angling its upper and lower
parts that they act as deflectors to divert any air currents which would tend to extin-
guish the flame. I prefer to combine with this protector means for supplying air to
effect more perfect combustion. For this purpose I may make air orifices in the lower
part of the said chamber and place over these an air spreader for directing the air on
to the periphery of the flame and connected with this spreader a ferrule or cylinder
which surrounds the gas nozzle, the air being let into the space enclosed by this ferrule
or cylinder thro' perforations in the air spreader.
The upper part of the ferrule or cylinder I prefer to provide with a rim or flange
leaving a space between itself and the inner or upper part of the cylinder.
The chamber may be provided on either its exterior or interior or both with copper
webs or wires or other material to be heated by the burner and act as diffusers
and heaters for the air issuing from the burner or for the air psssing at the exterior of
the burner or for both.
The apparatus may be arranged in any suitable position-for example, in the base
of a shaft or post, as explained in my said former Specification; or I may place it in
a suitable chamber at the upper part of a lamp or other post, means being provided
for ready access thereto.
The products from the said burner and from the sewer may pass either into the
lantern (if there be one) or they may pass away before they arrive thereat or they
may pass through a tube above the aforesaid burner or the appliance may be situated
in the lantern itself.
The burner described is not limited to the aforesaid application, as it may be
employed for cooking stoves or for other heating purposes.

Improvements in Means or Appliances for Exhausting and Con-
suming Foul Air or Gases from Sewers or other places containing
Foul Air or Gases and for Effecting Ventilation of the same,
applicable also for Heating Purposes.
I STEPHEN HOLMAN of 15 Great George Street in the City of Westminster
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 :—
My invention relates more particularly to apparatus of the class described in the
Specification of my Letters Patent No. 15519 of 1887.
The principal object of my present invention is to provide in connection with the
burner used in the said apparatus means whereby a much more perfect combustion of
the gas is ensured and the flame is protected from being accidentally extinguished.
According to my present invention I place on the top or at the nozzle of the
atmospheric burner a hollow chamber into which the gas and air are received before
combustion, the said gas and air leaving the said chamber by a slot surrounding the
said chamber about midway thereof, at which slot the flame issues.
The chamber is so shaped preferably by curving or angling its upper and lower
parts that they act as deflectors to divert any air currents which would tend to
extinguish the flame. I prefer to combine with this protector means for supplying
air to effect more perfect combustion. For this purpose I may make air orifices
in the lower part of the said chamber and place over these an air spreader for
directing the air on to the periphery of the flame and connected with this spreader
a ferrule or cylinder which surrounds the gas nozzle the air being let into the
space enclosed by this ferrule or cylinder through perforations in the air spreader.
The upper part of the ferrule or cylinder 1 prefer to provide with a rim or flange
leaving a space between itself and the inner or upper part of the cylinder.
The chamber may be provided on either its exterior or interior or both with copper
webs or wires or other material to be heated by the burner and act as diffusers and
heaters for the air issuing from the burner or for the air passing at the exterior of the
burner or for both.
The apparatus may be arranged in any suitable position-for example, in the base
of a shaft or post as explained in my said former Specification, or I may place it
in a suitable chamber at the upper part of a lamp or other post, means being provided
for ready access thereto.
The products from the said burner and from the sewer may pass either into the
lantern (if there be one) or they may pass away before they arrive thereat or they
may pass through a tube above the aforesaid burner or the appliance may be situated
in the lantern itself.
The burner described is not limited to the aforesaid application as it may be employed
for cooking stoves or for other heating purposes.
Figure 1 of the accompanying drawings represents in vertical section an arrange-
ment according to my present invention applied to apparatus of the class described in
the Specification of my aforesaid Patent 1551987. In this Figure 1 the burner
is shewn in elevation but an enlarged sectional views of it are shown in Figures 2. & 3.
A is the body of the post in which the apparatus is situated. B is the pipe by
which gas is supplied and b is the nozzle by which it issues for combustion.
C are the conical arrangements of webbed deflectors such as are described in the
Specification of my aforesaid former Patent.
Surrounding the nozzle b is the hollow chamber D into which the gas and air are
received before combustion. d is the slot by which the gas and air leave the chamber
and at which they are ignited. The curved and angled parts at d' act as deflectors to
divert air currents tending to extinguish the flame. d are the aforesaid air orifices
in the chamber D and E is the air spreader inside the chamber and leaving a space

page_text: between itself and the inside of the lower part of the chamber through which space
the air passes to the periphery of the flame. G is the aforesaid ferrule or cylinder
which surrounds the gas nozzle the air passing into the space within this ferrule or
cylinder by the perforations f in the spreader. g is the aforesaid rim or flange leaving
the space at g² between itself and the inside of the chamber D. hh are webs acting
as diffusers and heaters.
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 :-
1. A burner for apparatus of the kind described, or for cooking and heating,
consisting of the arrangement and combination of parts substantially as herein before
described and illustrated in Figure 2 of the accompanying drawing.
2. In an atmospheric burner for the purposes mentioned the combination of gas
nozzle and chamber surrounding it with a slot therein and means for diverting air
currents tending to extinguish the flame substantially as hereinbefore described and
shewn in Figure 2.
3. In atmospheric gas burners such as are referred to the combination of an air
spreader for directing air to the flame substantially as hereinbefore described and
shewn in Figure 2.
4. In atmospheric gas burners for the purposes mentioned the combination of
gas nozzle, surrounding slotted chamber air spreader ferrule or cylinder and air
admission openings with or without the webs and air deflecting arrangements substan-
tially as hereinbefore described and shewn in Figure 2.
5. The means or appliance for exhausting and consuming foul air or gas from
sewers or other places the said means or appliances consisting of the arrangement and
combination of parts as a whole substantially as hereinbefore described and shewn in
Figure 1.
