PROVIDIONAL OF BUITIVATION,
Improvements in Gas Lighting.
THOMAS ARTHUR GREENE 155 Cannon Street London E:C. Gas Engineer and
CHARLES MAYNARD WALKER of the same address Gas Engineer do hereby
declare the nature of this invention to be as follows:-
=
This invention relates to improvements in that class of gas lamps commonly
known as regenerative and is a developement of and an improvement upon Young's
invention described in the Specification of Letters Patent dated A.D. 1854
No. 567. For this purpose we construct a lamp with the central tube generator of
Young which is by preference cast in one piece with the body of the lamp and is
held by means of a connection to the central gas supply pipe which descends the
chimney of the lamp and passes into the generator at which point it is fitted with a
burner having a central air passage terminating in an air box below the burning
point the lamp is provided with a hinged ring fitted to receive a lipped glass, the
upper face of the ring is provided with a circular beading which fits into a
corresponding recess in the under part of the body of the lamp to exclude. air..
The action of the lamp is as follows-Upon the gas being lighted and the door closed
the escape of the heated products of combustion up the chimney, draws air through
the radial air passages into the generator, part of which air passes by the annular
passage to the mouth of the generator where it impinges against the projecting
ring of the burner and deflects the flame from the inside, outwards-the other part
of the air descends the central air passage of burner and is distributed to the under
side of the flame by the air box, which is perforated for that purpose with a
convenient number of holes-a circular deflector is fitted in a suitable position
above the burner and tends to draw inwards the points of the flame-further, in
order to use the lamp in situations exposed to the wind and the weather we
construct a cover which encloses the whole of the lamp except the door-this cover
terminates at the top with a curtained-plate which is provided with holes near its
outer edge by which the products of combustion escape-the cover is further.
provided with a number of air holes which are protected from the wind by a suitable
hood and the parts of the cover are so arranged that the disturbing influence of
the wind is compensated for.
Dated this 2nd day of November 1893.

We THOMAS ARTHUR GREENE 155 Cannon Street London E.C. Gas Engineer
and CHARLES MAYNARD WALKER of the samo address Gas 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 :-
1854
This invention relates to improvements in that class of lamps commonly known
as regenerative and is a development of and an improvement upon Young's
invention described in the Specification of Letters Patent dated A.D.,.
No. 567 and is adapted to burn in the open air when protected by a case or
covering, and also for domestic and other uses without such cover or case. For this
purpose we construct a lamp preferably of cast iron with the central tube
generator AA of Young which is by preference cast in one piece with the
body B B of the lamp, the body of which is formed at its upper part as a collar
into which the chimney W is fitted and secured by means of screws or other'
ordinary contrivance and is provided with radial passages V for air-the gas supply:
pipe C passes downwards through the chimney W and is firmly fixed by the
back-outs F F-at the lower of which back nuts the burner D is attached, the
burner is constructed with a central air passage X terminating in an air box' E
below the burning point perforated with holes, the lamp is provided with a
hinged ring or door S fitted to receive a lipped glass, the upper face of this ring is!
provided with a beading which fits into a corresponding recess or matrix in the
under part of the body of the lamp and is also fitted with an ordinary catch or
fastening J-the chimney W. is provided with a stretcher H preferably cast with
the chimney, having back nuts G, G screwed on the gas supply pipe Cand placed
both at the under and upper surfaces of the stretcher a circular deflector M
with a central aperture is fitted inside the lamp, the upper part or fitting of
which, is immediately above the air holes L L. We find the addition of a
circular shoulder T on the base of the generator greatly increases the efficiency
of the flame. The action of the lamp is as follows, when the lamp is lighted
and the hinged ring carrying the glass is closed, the draught in the chimney
draws air through the radial air passages V part of which air passes down the
centre of the burner and issues through the holes in the air box E and part
passes down the annular space formed by the outer wall of the burner and the
inner wall of the generator and issues at the mouth thereof the effect of these
two currents of air being to feed the inner and the outer surfaces of the flame
with heated air, and causes the flame to assume its proper form, air also enters
through the air-holes L L, and the products of combustion escape. up the
chimney W. The details of the construction of the gas burner are shewn in
Fig. 2 of the accompanying drawings. When it is intended to use the lamp in
the open air, we enclose the lamp in a suitable case or cover.
In the accompanying drawings Figs. .1 and 2
A is the generator.
B is the body of lamp.
C is the gas supply pipe.

X is the central air passage leading to air box.
O is the screwed fitting to enable the burner to be taken apart for cleaning.
P is the screwed plug for removing debris.
R is the gas flame.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is
The combination of parts substantially as hereinbefore described and set forth in
the accompanying drawings as and for the purposes of constructing regenerative
lamps.
