Improvements in the Means e uployed in Burning Gas or Oil for
Lighting or Heating Purposes.
I WILLIAM POTTS No. 30 Castle Street Edinburgh, Pneumatical Engineer &c.
do hereby declare the nature of this invention to be as follows:-
These improvements specially refer to the removal of some objections to
burning gas viz., too rapid draught in the Argand burner, the discolouration of
ceilings from a vertical flow of the products from combustion, a comparatively
very deficient illuminating power when contrasted with the electric light; some
of these objections, it is assumed these improvements remove entirely.
These improvements relate to increasing the light from burning gas, and oil, and
as relates to gas used internally, its slower burning, and consequently its better
combustion, the avoiding discolouration of ceilings, the heating gas on its way to
the burner, and the reflection of the light.
The slower burning, and better combustion of gas, also the non-discolouration of
ceilings, arise from the products from combustion being not discharged on a
vertical, but on a lateral line of flow, consequently slower.
The gas is heated by having to pass through a coil of tube forming the burner
socket, in lieu of the usual straight passage. The reflecting arises from a metal or
other reflector resting in and over the burner glass, which prevents a vertical flow
of the products of combustion. Figs. 1 and 2 relate to the improvements referred
to, these have the reflectors over, and resting in the glasses, by means of wires
shown by dotted lines, which separate the reflectors and glasses, to allow of the
escape of the products from combustion laterally, and into the general air of a
room. Figs. 1 and 2 each show the coiled tube gas passage. Fig.

current of air to pass to the interior of the flame the corrugated outline much
increases the surface for burning, and for this it will require a tube of the same
form.

before stated, will be of great use in burning oil.

Improvements in the Means employed in Burning Gas or Oil for
Lighting or Heating Purposes.
I WILLIAM POTTS Pneumatical Engineer, now residing at No. 2 Alva Street
Edinburgh 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 inventions in this Patent are illustrated and described in the drawings and
Complete Specification, and from these elucidatory documents can be made and
applied by the persons whose callings these refer to.
These improvements relate to increasing the light from burning gas and oil, and
as relates to gas used internally, its slower burning, and consequently its better
combustion, the avoiding discolouration of ceilings, the heating gas on its way to
the burner the reflection of the light, and an improved burner.
The slower burning, and better combustion of gas, also the avoiding dis-
colouration of ceilings, arise from the products from combustion being not
discharged on a vertical but on a lateral line of flow, consequently slower. The
gas is heated by having to pass through a coil of tube forming the burner socket in
fieu of the usual straight passage. The reflecting arises from a metal or other
reflector resting on and over the burner glass, which prevents a vertical flow of the
products from combustion. Figs. 1 and 2 relate to the improvements referred to.
These have the reflectors over, and resting on the glasses by means of wires shown
by dotted lines which separate the reflectors and glasses to allow of the escape of
the products from combustion laterally, and into the general air of a
Figs. 1 and 2 each show the coiled tube gas passage. Fig. 1 shows a burner on
the Argand principle of a current of air in the interior of the coiled tube socket,
as that is brazed externally air-tight.
room.
Fig. 2 shows an ordinary fishtail nib, but Fig. 1 has three of these nibs placed
level on the top of the coiled tube. The arrows show the current from
combustion.
Fig. 3 shows a street gas lamp, in which air can only enter at the bottom, which
avoids damping the flame, and also the condensation of the products from
combustion in the lamp, both are highly detrimental to light. The pneumatic
outlet B draws vapour out on the line the arrows take but allows no air to
enter it from the exterior. The pan holds the burner glass F, and is held as
shown by the brackets connecting the upper and lower parts of the lamp. The
glass G is held as shown by curved loops resting in and moving on pins in the
brackets which arrangement permits these loops to be turned upwards to release
the glass which is used to prevent lateral blowing of wind interrupting the flow
of air to the burner. The burner shown here is the triple flat flame burner
described in connection with Fig. 1.
Fig. 4 shows the form for an oil lamp wick on the Argand plan of allowing a
current of air to pass to the interior of the flame, the corrugated outline much
increases the surface for burning. This form of wick will require a tube of the
same form.
The forms of glasses with reflectors shown in Figs. 1 and 2 for reasons
before stated will be of much benefit in burning oil.
Referring to the street lamp Fig. 3 the outline of reflector, and that of the lower
glass, may be varied if it is desired to do so, as also can the arrangement for the
admission of air at bottom.
Claims under this Patent.
1. I claim the arrangement for the use of a reflector by preference of metal over
a gas or ol burner glass, on which it rests by wires, as shown, separating about
inch, to allow combustion products to only escape laterally, for the reasons stated.

page_text: 2. I claim the forming sockets to receive flat flame gas burner nibs of a coil of
tube issuing from the screwed socket.
3. I claim the fixing on the top of such a coil of tube socket three or more flat
flame nibs, as shown and described.
4. I claim the plan to construct gas or oil lamps as shown Fig. 3 to have a
reflector over burner over the glass an outlet construction Patented No. 11500
which allows no air to enter externally, the glass at bottom to stop wind currents.
5. I claim a corrugated form for oil lamp wicks as shown Fig. 4, to enlarge the
surface burning.
