‹ 1, George Watson Lamb, of 5 Colstone Terrace, Dunstans Road, Peckham Rye,
Surrey, Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is, to construct and arrange the burner portions, of
what are termed Regenerative Gas Lamps, in a novel manner whereby a great
intensity and brilliancy of flame is produced and the maximum of flame inore rapidly
obtained.
According to the usual construction of regenerative burners a supply of highly
heated air is given at the point of combustion of the gas by a tube either from within
the gas supply or from the outside thereof or from both inside and outside thereof, in
which arrangement, several tubes are used in addition to the tube by which the gas is
furnished.
Now by this invention I make use of one tube only and so form the upper part of
it that gas is supplied in minute streams to the interior where the gas impinges
against a baffle plate of gauze or solid metal to charge a lower chamber at an uniform
pressure for consumption at the lower part where it is deflected by a button into a
circular sheet of flame, the flame then striking against a ring plate secured to the
tube but at a distance from it so that air from a jacket (gauze lined) may act upon the
top surface of the ring of flame and cause it to spread to the outer edge of the ring
plate to enable the full lighting power of the gas to be obtained with perfect combus-
tion, the exterior of the flame being supplied with air from the perforations of the rim
which carries the globe or glass bason.
The gas supply tube is open at its lower end but the button or spreader is secured
to a central stein in which it is adjustable to regulate the opening or ring slit from
which the flame emerges.
Instead of feeding the gas downwards it may be fed upwards, in which case I
connect a stem or branch to the upper end of a bracket, pedestal, or other ordinary

page_text: supply to a burner; and I so arrange the stem that the gas is furnished in minute
streams to a chamber, near to the upper part. of which the button or spreader is fitted,
so that the gas issues in ring form, and is spread still further by the ring before
mentioned.

*COMPLETE SPECIFICATION.
An Improvement Connected with the Burners of Gas Lamps.
I GEORGE WATSON LAMB of 5 Colstone Terrace, Dunstans Road, Peckham Ryc,
Surrey, Engineer, do hereby declare the nature of my said 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 this invention is to construct and arrange the burner portions of what
are termed the Regenerative Gas Lamps in a novel manner whereby a great intensity
and brilliancy of flame is produced and the maximum of flame more rapidly
.obtained.
According to the usual construction of regenerative burners a supply of highly
heated air is given at the point of combustion of the gas by a tube either from within
the gas supply or from the outside thereof, or from both inside and outside in which
arrangement several tubes are used in addition to the tube by which the gas is
furnished.
Figure 1 is a sectional elevation of a regenerative lamp in which the gas is
supplied in a downward direction.
Figure 2 is a transverse section through the line a, c.
Figure 3 is a sectional elevation of a lamp in which the gas is supplied in an upward
direction.
Now according to my invention which I show in the annexed drawings I make use
of one tube or casting A, E, H, K, only and I form the upper part B with holes that
gas is supplied in minute streams to the interior C where the gas impinges against a
baffle plate D of gauze (or solid metal) to charge a lower chamber E at an uniform
pressure for consumption at the lower part where it is deflected by a button F into a
circular sheet of flame, the flame striking against a ring plate & secured to the air
supply tube H, which tube H is supplied through horizontal branches I, see Figure 2,
so that the air in its travel passes through a gauze J and thence acts upon the top

page_text: surface of the ring of flame and causes it to spread to the outer edge of the ring
plate G to enable the full lighting power of the gas to be obtained with perfect
combustion. The exterior of the flame is supplied with air by the perforations of the
rim K which carries the globe or glass vason L and also its hinged rim M.
The gas supply tube is open at its lower end, but the button or spreader F is
secured to a central stem which is adjustable to regulate the opening or ring slit from
which the flame emerges.
The fumes and products of combustion pass up the passages N to the chimney or
outlet P within which the gas supply pipe Qis arranged the heat from the products
of combustion raises the temperature of the gas while descending down the pipe Q
and from the heat imparted to the air jacket H and to the parts A, E, from their
proximity to the flame the gas is heated to great intensity before it gets to the point
of consumption at F.
R is a screen from which a reflector can be suspended if desired.
Instead of feeding the gas downwards as at Figure 1 it may be fed upwards, see
Figure 3, in which case I connect a stem or branch Q to the upper end of a bracket,
pedestal or other ordinary supply to a burner, and so arrange the stem Q that the
gas is furnished in minute streams to a chamber C and from thence through the pipe E
near to the upper part of which the button or spreader F is arranged so that the gas
issues in ring form and is spread still further by the ring G before mentioned. The
arrangement of the air passages is the same as that described for Figure 1.
It will be observed that the glass globe or bason L is hermetically sealed at the
bottom so that air entering the bason can only pass through the apertures in the
ring K. S, S, Skeleton supporters for the upper part of the lamp.
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. As a regenerative gas lamp the particular construction and arrangement shown
at Figure 1 and in which one casting, indicated by A E H. K, only, constitutes the
central portion or lamp proper instead of making said parts from several pipes or
castings as by systems now in vogue.
2. The particular construction or arrangement of pedestal or bracket lamp in which
the lamp proper H. K. constituting a single casting or pipe is employed as set forth
and shown at Figure 3 of the annexed drawings.
