PROVISIONAL SPECIFICATION.
Improvements in the Arrangement and Construction of
Regenerative Gas Lamps.
I, JAMES LEWIS, of 6 Gloucester Terrace, West Green Road, Tottenham in the
County of Middlesex, Engineer, do hereby declare the nature of this invention
to be as follows:-
This invention relates to improvements in the arrangement and construction
of regenerative gas lamps or burners and has for its object to simplify the con-
struction of such burners or lamps so as to render same less liable to get out of
order and otherwise improve their effectiveness while at the same time to effect
considerable economy'in their cost of production.
For these purposes I arrange and construct the several parts of a regenerative
gas lamp as follows:-
The gas is supplied through a central vertical pipe to the burner-which is
advantageously a jet burner with a series of small holes-the said pipe being
connected to either a vertical supply pipe or to a side connection out of chimney
so as to form a bracket lamp. Over the burner is arranged a box or hollow
chamber to which air is supplied in either of the three ways hereinafter
described approximately circular in form with flat or nearly flat top and bottom
thereto with Hange on bottom side of outlet to direct the air on Hame. The
bottom has a clear opening around the gas pipe for the heated air to pass out to
support combustion and the products of combustion have a free passage away to
the chimney all round the said chamber.
The air supply is conducted to this chamber from the exterior of the chimney
by means of (1) a single large pipe or passage in shape of an elbow or bend and
descends vertically and centrally in the lamp to the said chamber or (2) in place
of the said single large passage two or more smaller pipes or passages entering
the said heating chamber centrally or (3) by means of a number of small pipes
arranged towards and around the outer edge of the said heating chamber-in this
case the small air tubes will pass through the plate on end of chimney and outside
of said chimney.
In the case of No. 1 arrangement a dise or baffle plate having a larger area than
the inlet of the said large tube is arranged and mounted horizontally beneath
such inlet in the said heating chamber so as to spread the air current therefrom
and prevent its passing in a direct line to the burner through the outlet of the
chamber thus dispensing with the use of wire gauze or the like over such outlet
and a similar baffle plate is mounted to act in a similar manner with No. 2
arrangement while with No. 3 arrangement this said baffle plate is dispensed with
as the bottom of the chamber acts as a baffle plate to the inlet currents.
**
In each arrangement the gas inlet pipe (unless the gas be admitted from below
as on a pillarlamp) and the air supply pipe or pipes to which latter is firmly
secured the said heating chamber and burner-may be secured to a ring or
hollow drum of a diameter corresponding with the internal diameter of the
chimney to which the whole of the parts can thus be readily attached or detached
by means of screws or other suitable fastenings.
The bottom of the heating chamber forms a disc for spreading the flame and
also ensuring the heated air coming in due contact with the top side of flame and
the burner and such heating chamber are enclosed by a glass globe having an
opening in the bottom thereof covered with wire gauze to admit air to the under-
side of the flame or if desired double glasses may be used as described and illus-
trated. in the Specification and drawings of an invention for which I have received
Letters Patent dated the 19th May 1885 No. 6154.

heating chamber and part of the air-inlet pipe or tubes are sunk down into and
surrounded by the glass globe or globes which glasses may be of any suitable
form to suit the purpose.

Improvements in the Arrangement and Construction of
Regenerative Gas Lamps.
I, JAMES LEWIS, of 6 Gloucester Terrace, West Green Road, Tottenham in the
County of Middlesex, 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 relates to improvements in the arrangement and construction
of regenerative gas lamps or burners and has for its object to simplify the con-
struction of such burners or lamps so as to render same less liable to get out of
order and otherwise improve their effectiveness while at the same time to effect
considerable economy in their cost of production.
For these purposes I arrange and construct the several parts of a regenerative
gas lamp as follows:-
Referring to Figure 1 of the annexed drawings-the gas is supplied through a
central, vertical pipe a (as shown in the drawings hereto annexed Figure 1 of
which shows a vertical section of a regenerative gas lamp arranged and con-
structed in accordance with my invention) to the burner which is advan-
tageously a jet burner with a series of small holes arranged in a circular form the
said pipe being connected to either a vertical supply pipe a* as shown or to a side
connection a** out of chimney (as shown by the dotted lines) so as to form a
bracket lamp.
Over the burner is arranged a box or hollow chamber to which
air is supplied in either of the three ways hereinafter described-approximately
circular in form with flat or nearly flat top and bottom thereto and with flange
forming an annular space 2 around the enlarged part 2 of the pipe a this flange b
being formed on the bottom side of outlet to direct the air on to flame.
bottom thus having the clear opening around the gas pipe for the heated air
to pass out to support combustion and the products of combustion have a free
passage e away to the chimney d all round the said chamber.
The
The air supply is conducted to the chamber from the exterior of the chimney
by means of (1) a single large pipe or passage e in shape of an elbow or bend and
descends vertically and centrally in the lamp to the said chamber bor (2) in
place of the single large passage e two or more smaller pipes or passages (not
shown in the drawings) enter the said heating chamber centrally or (3) by means
of a number of small pipes & (shown in Figures 2 and 3 of the drawings) arranged
towards and around the outer edge of the said heating chamber b in this case the
small air tubes will pass through the plate on end of chimney and outside of
said chimney which in this case would be made much smaller in diameter.
k
In the case of No. 1 arrangement a disc or baffle plate having a larger area
than the inlet or diameter of the said large tube e is arranged and mounted hori-
zontally beneath such inlet in the chamber b so as to spread the air current
therefrom and prevent its passing in a direct line to the burner a¹ through the
outlet passage 2 of the chamber 6 thus dispensing with the use of wire gauze or
the like over such outlet and a similar baffle plate is mounted to act in a similar
manner with No. 2 arrangement while with No. 3 arrangement (shown in
Figures 2 and 3) this said baffle plate is dispensed with as the bottom 6* (see
Figures 2 and 3) of the chamber acts as a baffle plate to the inlet currents.

page_text: "
In Nos. 1 and 2 arrangements the gas inlet pipe a (unless the gas be admitted
from below as on a "pillar lamp) and the air supply pipe c or pipes-to which
latter is firmly secured the said heating chamber may be cast or otherwise
secured to a ring or hollow drum g of a diameter corresponding with the internal
diameter of the chimney to which the whole of the parts can thus be readily
attached or detached by means of screws or other suitable fastenings.
The bottom (externally) of the heating chamber forms a disc or surface for
spreading the flame and also ensuring the heated air coming in due contact with
the top side of flame and the burner and such heating chambers are enclosed by
a glass globe f having an opening in the bottom thereof covered with wire
gauze to admit air to the underside of the flame or if desired double glasses may
be used as described and illustrated in the specification and drawings of an inven-
tion for which I have received Letters Patent dated 19th May 1885 No. 6154.
A shield (either ornamented or not and of any desired shape form or design)
is mounted on the outside of the chimney (Figure 1) to protect and cover the
air inlet e as in Figure 1 or air inlets as in the other arrangements.
Figure 4 shows a modification of No. 1 arrangement-the only difference being
in the shape of the top of the chamber which in this case is conical (as shown)
at .
The whole of the parts as shown in Figure 4 are cast or formed together and
are secured in position in the chimney by screws or otherwise and the glass is
then attached and the lamp is complete and ready for use.
In order to reduce as far as possible the shadow thrown upon the ceiling I find
it both convenient and advantageous to so arrange the parts that the burner a¹
heating chamber and part of the air inlet pipe (or pipes) are sunk down into -
and are surrounded by the glass globe or globes f which glasses may be of any
suitable form to suit the purpose.

Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1. The improved arrangement and construction of " regenerative gas lamps
in which part of the gas inlet pipe enlarged pipe a burner a baffle plate air
heating chamber and part of the air inlet pipe (or pipes) e are sunk down into
and are surrounded by the glass globe of any suitable form substantially as and
for the purposes herein before described and illustrated in Figure 1 of the drawings
hereunto annexed.
2. I claim a regenerative gas lamp in which the heating chamber with the
series of air inlet pipes are sunk down into and are surrounded by the glass
globe substantially as and for the purposes herein before described and illus-
trated in Figures 2 and 3 of the drawings hereunto annexed.
3. In a regenerative gas lamp I claim a heating chamber such as and air
inlet pipe (or pipes) such as e in combination with the baffle plate a³ to prevent the
air passing in a direct line to the flame substantially in the manner and for the
purposes set forth and illustrated by Figures 1 and 4 of the drawings hereunto
annexed.
4. In a regenerative gas lamp I claim a heating chamber such as in com-
bination with a series of pipes such as arranged towards and around the outer
edge of the said heating chamber, so that the bottom of the box or chamber b
acts as a baffle plate io deflect the air inlet currents and so prevents same passing
direct to the flame substantially in the manner and for the purposes herein before
described and illustrated in Figures 2 and 3 of the drawings hereunto annexed.
