PROVISIONAL SPECIFICATION.
An Improvement in Gas Lamps and Burners.
LOUIS BRUERS, Lamp Manufacturer, 47 Avenue de la Porto de Hal, Brussels,
Belgium do hereby declare the nature of this invention to be as follows:-
My invention consists of improvements in the construction of Gas and other
Lamps directed chiefly to greater regenerative power produced by the application
of radiating discs of metal or other substances of a form similar to those shewn
at A Fig. 6. which I, at present, prefer to arrange as on Figs. 2, 3 and 4, by which
means the furnace surface is greatly increased; the discs to be placed spiral or
horizontal and to superpose with the openings adjustable as required.
The outer conting of metal or other substance is onamelled by which enamelling
the radiation is prevented and the hot air returned through A Fig. 1 to ensure a more
perfect combustion.
I place an opening at or near and similar in size and form or otherwise as at C.
Fig. 1., to improve the temperature and at the same time reduce the action of beat
upon the reflector R. Fig. 1.
The Burner of my invention substitutes a circular slit or opening (as shown in
Fig. 5.) for the usual perforations for the exit of gas at the point of ignition,
allowing of corrosive or other impurities being removed with increased facility, at
the same time producing greater steadiness and brilliancy of flaine. The circular
gas exit is modified and regulated by the adjustable screw Y Fig. 8. Dust, moisture
and other foreign matters are deposited and retained in the lower portion of tube W
Fig. 8. The improvements in the burner are also applicable to small burners,
usually attached to gus Brackets, Chandeliers and portable office or table lamps, their
light weight rendering them specially adapted for those lights. These improvements
apply to any form of flame or to the consumption of any mixture of gas with air,
carbon or other illuminants. The burners can be made of metal or any other
suitable substance or in parts of metal or other suitable substance, and any size.
I reserve the right of using the small round apertures Z Fig. 7, or any
modification thereof applied to my aforesaid improvements or to any portion of my
burners.
In opening the usual glass shade of Regenerative Lamps the glass on a sudden
dropping of the glass and the frame containing it is liable to breakage. My invention
embraces a small case containing a spring and pulley (X Fig. 1.) by which
the lowering of the glass and its frame are controlled, and also in closing of the
same.
COMPLETE SPECIFICATION.
An Improvement in Gas Lamps and Burners.
I, LOUIS BRUERS, of 37 Southwark Bridge Road, in the County of Surrey, Lamp
Manufacturer 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 :-
My invention relates to improvements in the construction and arrangement of
Gas lamps, in which I employ a cylinder with radiating partitions and gills (or
they may be radiating discs) fitted within the body of the lamp and forming hot
chambers or partitions through which the air for feeding the flame has to pass and.

of the light.
In Figure 1 of the annexed drawings, I have shown a vortical section of a lamp
constructed according to my invention. A is a hollow casting fitted--with a bell
shaped cover B which rests on a shoulder at its upper part. In the casting A, are
apertures or passages C for allowing the air to flow from the exterior to the
interior, and below the hollow casting is a double concentric cylinder D, seen in
the plan view Figure 2, divided by partitions and gills E, E into a number of
compartments F, F, which extend downwardly towards the burner, the air for
feeding the burner after traversing the heated hollow casting A then passes down
these compartments and becomes further heated before reaching the burner H fitted
nt the lower end of the gas supply pipe G.
The cylinder is supported by screwing onto the lower end of the gas supply
tube G and in its turn supports the hollow casting by taking into flanges on its
lower edges.
The lower end of the inner concentric ring of the cylinder is formed as a
deflector plate I having perforations around the burner, and the outer concentric
ring is furnished with a reflecting bell J.
The glass K is supported in a movable frame L, hinged at M to a fixed frame N
in which a series of small holes N₁ are pierced through which air from the outside
can pass for the purpose of keeping the reflector cool and to feed the flame and in
order to prevent accidents by the sudden release and fall of the glass frame, I employ
a spring pulley P with a cord or chain Qone end of which is attached to the glass
frame M and controls the lowering or fall of the lattor.
In the space left between the mouth of the cover B and the frame N, metal or
wire gauze R is inserted to check any sudden inrush of air, which flows through
this space, and becomes slightly warmed in its passage to the hollow casting A;
is again further heated in the hot air compartments or pockets F, and feeds the
flame at the burner. The products of combustion escape upwards through the inner
and outer walls of the double cylinder D & serve to maintain these cylinder &
casting at a high temperature, and finally issues from the chimney S.
In lieu of the double cylinder, or in addition to it, I sometimes employ one or more
circular plates, perforated and with radial segments, such I show in the sectional
and plan views, Figures 3, and 4, respectively, or with hit and miss openings as
shown in section and plan views Figures 5, 6 and 7. These circular plates are used
where it is required to feed the flame with air at a very high temperature, and
when placed one above another form covers for the hot air chambers F. The
temperature may be regulated by arranging one or more above each other, their
apertures being made either to correspond or be opposed, in which latter case the air
would be compelled to take a longer or zig-zag course before reaching the burner and
thus become more highly heated.
In Figures 8 and 9, I show an elevation and section respectively of my improved
form of regulating burners; the burner proper is in two parts H, H³, which may be
made to approach each other more or less by a simple screwing up action of the
lower half which has a stem T tapped to screw into the upper half H¹ and so
regulate the intensity of the sheet of gas flame issuing from between them. The lower
half may be entirely removed for detaching any carbon or dirt which may be
accumulated in the burner.
Figures 10, 11 and 12 illustrate in elevation, section, and sectional plan, respectively,
a simple and convenient arrangement for regulating the quantity of gas flowing to
the burner. In this arrangement the gas passes down the central gas supply tube G
und out into the outer tube U by the lower end and thence it issues through
perforations at the upper end, as shown by the arrows. V is a screw plug which
may be turned by hand so as to regulate the amount of opening and consequently the
quantity of gas which is permitted to pass from the inner supply tube to the outer
tube for burning at the apertures.

page_text: Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The particular arrangement and combination of all the parts and constituting a
regenerator gas lamp, as set forth and as shown in the drawing, Figure 1.
2. The employment of either of the open meshed discs, shown at Figures 3, 4, 5, 6
and 7 of the drawings, in the central chamber of the lamp between the burner and
the upper part of the bell for giving off the heat to the inflowing air which passes
down in a divided state and is brought into a fit state for combustion with the gas,
as described.
3. The employment of the skeleton frame shown at Figure 2 as a single article
occupying the chamber between the burner and the bell for rarifying the inflowing
air and for the purpose of feeding the gas flame with hot air.
4. In connection with a hinged glass bason K of regenerative gas lamp, the coiled
spring for gradually lowering said bason and for preventing shocks if suddenly
opened, as set forth.
5. The burner shown at Figures 8 and 9 of the drawings by which the size
of ring frame can be regulated by the screw action of the lower part, as
described.
6. The particular form of burner shown at Figures 10 and 11 of the drawings,
within which is a well for receiving dirt, or other foreign matter, also moisture,
the lower part being provided with a screw for regulating the supply of gas to the
apertures.
