PROVISIONAL SPECIFICATION.
Improvements in Gas Lamps and Burners for the same.
We, JOHN MARSON LAMB, of 119 Finchley Road South Hampstead in the County
of Middlesex, Engineer and JOHN LAMB, of 13 Fairbridge Road, Islington in the
County of Middlesex, Gentleman, do hereby declare the nature of this invention to be
as follows:-
Our present Invention has reference to the class of "Gas lamps described in our
former Provisional specification No. 12,709 granted to us as of the 6th day of
October 1886.-This Invention consists in constructing the Argand type burner,
without the drilled or pressed holes, by making the gas issueing piece seperate in the
form of a ring or collar in one or more pieces of metal, steatite, or any other suitable
material with vertical grooves on the exterior, or on the interior, or on both the
exterior and the interior of the ring. The case of the burner is bored out to receive
the grooved ring and is screwed together by the inner lineing, or deflecting plate.
The seperate rings can be made with serrated sides or of any other formed channell for
a Gas issue, and the burner can also be fitted with a small air directing cup when
required. The Air Heating chamber we construct so as to form a sort of reservoir
within it for the super heating of a portion of the air and for diffuseing it equally over
the surface of the flame, it is made by fixing an outer taper cylinder with the small
end upwards and lined with a partial perforated taper cylinder with the small end
downwards. The small end being of such a suitable size so as to leave a clear open
space round the outside of the burner. The opening between the two taper cylinders
we cover up with a perforated ring of metal curled up inwards, or we can make the
inner perforated cone of sufficient length and curl it outwards to join the outer
cylinder or we can make the inner cone perforated at the top only and less tapering,
and the perforated ring of metal extending from the outside and curled up inwards
beyond the edge of the inner cone and with an air space between the cone and the
perforated bottom plate, suitable baffle or directing plates can be fixed inside the air
reservoir for still further heating the air when required. The covering to the super
heating air chamber can be made either concave, convex, flat, or other shape with

page_text: the perforation extending up round the burner or otherwise according to require-
ments, but in all cases with a clear open space round the burner, or burners. The
air that enters the chamber becomes highly heated and passes rapidly through the
burner and the open space round the burner which depresses the flame while the air
that enters the second chamber becomes super heated and feeds the entire surface of
the flame in a greatly rarefied condition. The lamp is held and fixed together by a
casting that we will call the crown piece it consists of a centre body through which
the gas supply and burner are fixed centrally with the lamp. The under side has a
downward rim to which the air chamber is screwed, extending from this rim to the
body of the lamp is a series of tubular passages which turn downwards and deflect
each supply of air into the heating chamber. The body of the lamp is made with a
series of holes to correspond with the inletts of the crown piece the ends of which
are screwed to receive a screwed collar or nut by which the lamp is fixed together.
The products of combustion pass between the air passages and the body into the
hood and chimney. In making large lamps the crown piece can be made with a
series of deflecting inletts some extending more inward to supply the air generally.
The glass bulb can be made with an edge round the lighting hole to receive a
metal ring by which a chain or quadrant can be hung or pivoted for closing up the
hole automatically by either an entire glass or metal ball, or half, or portion of a
ball or stopper attached to the chain or quadrant.

A is the body of the burner constructed either wholly or partially of metal, a the
usual cross brauches leading the gas thereto, A¹ the grooved or serrated gas nozzle
which can be made either as a complete ring or in sogments either of metal steatite or
other suitable material. The Gas nozzle can be made grooved on the exterior or on the
interior or on both the exterior and the interior with straight sides as shewn at
Fig. 5 or it can be made with bevelled sides, when the grooves are made on the
interior of the ring part of the exterior would be cut away at the bottom edge to
allow the gas to pass freely under it. B the cylindrical collar with gas deflecting
shoulder B on which the grooved ring rests and the quantity of gas required regulated
by screwing the collar up or down into the body of the burner A. C is the open
air chamber in which is formed a superheating air reservoir D with perforated or
other openings at the bottom. Fig. 1 shews the combined open and perforated
reservoir air chamber formed by the outer taper cone C with a partially perforated
inner cone C. Fig. 2 shews the method of constructing the reservoir air chamber
by the inner perforated cone C perforated top and bottom and extending outwards
to join the outer cone C¹. Fig. 3 shows the perforated concave bottom reservoir
air chamber and the partially perforated inner cone C detached at the bottom to
admit a small quantity of air. The Reservoir or second air chamber that surrounds
the first open air chamber can be made of any suitable form at the bottom for
administering the superheated air over the tail of the flame, and can also be made
with internal baffle plates or projections for still further heating the air when
required. In making the combined air chamber. The first air chamber that
surrounds the burner leaves a clear open annular space round the outside of the
burner for the purpose of creating a current of heated air at a great velocity on to the
flame, at its point of issue from the burner while the second or reservoir air chamber
receiving the air from the first chamber it becomes superheated in the reservoir D,
and impinges on the tail of the flame with decreased velocity but in a much higher
heated state and thereby engages the escaping particles of carbon and brings them
into illumination. The body of the lamp we can construct as described in our former
specification or of any other suitable form or combination. This lamp can be made
with a single burner or any number of burners arranged in one lamp on the system
described in our former specification No. 12709 with the air cage of the burner to
correspond in shape or otherwise with the outer air chamber. In Fig. 4 we shew an
improved form of ring burner, it is constructed by an inner cylindrical body A having
two or more gas passages from the centre supply and an outer cylinder a, secured to
the inner one by the cap piece a', and air tubes a passing between the two cylinders,
or we can dispense with the separate cap a' the same can be formed on the cylin-
drical piece A and the air tubes instead of passing between the two cylinders can be

page_text: made to pass between the branch gas passages of the piece A. B is the inner lining
with the gas deflecting shoulder B which carries the gas issueing ring or nozzle A,
Qis the glass globe with hole at the bottom having an outwardly turned edge, R the
stopper valve of any suitable shape, R¹ a quadrant arm jointed or hung on a ring of
metal R² which is fastened on the edge of the globe, or a chain attachment can be
used when required.
Having now particularly described and ascertained the nature of our said invention
and in what manner the same is to be performed we declare that what we claim is
1. The combination and arrangement of parts constituting a regenerative gas lamp
either as a suspension, pillar, or other lamp, substantially as herein before described
and illustrated by the accompanying drawings.
2. In Regenerative Gas lamps the combination with the burner or burners of a
combined air chamber consisting of two chambers in one the first or inner one
forming an open chamber surrounding the burner leaving a clear open annular space
round the outside of the burner or outer burner when more than one are employed.
The second one forming a superheating chamber with perforated or other openings
at the bottom surrounding the first chamber substantially as and for the purposes
herein before described and illustrated by Figs. 1. 2. 3. of the accompanying
drawings.
3. In Gas burners a grooved or serrated ring forming the gas issuing piece or
nozzle fitting between two concentric cylinders substantially as hereinbefore described
and illustrated by Fig. 5 of the accompanying drawings.
4. In Gas lamps, a burner constructed with concentric cylinders and air tubes
