"IMPROVED MEANS
ARTHUR HENRY ROBINSON of 4 Clyde Road, Dublin Ireland
AND APPARATUS TO BE USED IN CONNECTION WITH GAS AND OTHER BURNERS FOR
INCREASING THE BRILLIANCY OR ILLUMINATING POWER THEREOF ".
My Invention has for its object to increase by a simple and inexpensive means
the brilliancy or illuminating power of Gas or other fluid consumed in Lamps or
Burners;
it also relates to further improvements in the invention described in the
Provisional Specification lodged with my application for Letters Patent, N° 5238,
dated the 2nd Nov* A.D. 1882. According to one method the said Invention
relates to the construction of a Gas Lamp wherein the Gas and Air are separately
heated before they combine and when combined and in combustion are super-
heated. To effect this object I construct a cap or cover having within it a Chamber
for heating the Gas, the said Cap or Cover being also a means of superheating the
air and gas in combustion, as referred to in my aforesaid Provisional Specification
The said cap or cover is provided with a neck or funnel which descends from the
bottom of the heating Chamber and is surrounded by the sides of the Cap or Cover,
which also descend a suitable distance. The said neck or funnel is provided with a
side aperture or apertures in proportion to the quantity of consumed Gas and Air or
Vapour to be let off. It is further provided with an adjustable mouth piece for
regulating the apertures, and receiving the chimney hereinafter referred to.
The said cap or cover is also provided with tubes one conducting the gas to the
heating Chamber, and one from thence to the burner: Over the said cap or cover I
place a shade or covering, (which may be a part reflector) which descends a suitable
distance in some cases to the point where the burner is supplied with air; this shade
or covering is carried by the inner cap or cover. Within and encircling the walls
or sides of the outer shade or covering I place a worm or spiral tube, the free end
of which is provided with holes to admit the passage of air, the other end
communicating with the said burner.
The Cap, shade & Burner are carried on a pillar stand or in any suitable
manner
The operation of a lamp such as described, would be as follows. The chimney of
the lamp is connected to the neck or funnel-before referred to; on the lamp being

page_text: lighted, the Gas in its passage through the chamber is heated to a high degree, and
so conveyed to the burner; the air which supplies the burner is also heated in its
passage through the worm, by the close proximity of the worm to the Gas heating
Chamber and the Chimney, and also by the heated Vapour, which passes off through
the apertures in the neck or funnel and thence downwards through and around the
tubes conveying the air to the burner.
In lieu of the said worm I may employ a heating Chamber provided with the
necessary tubes similar to the Gas Chamber heating the incoming air.
When desirable I attach a ring or top piece to the chimney the said ring or top
piece, being open, at the top. and provided with a suitable side opening or
openings. Over said attachment I place a shade or covering which may be of glass
or other suitable material. The said shade or covering closes the top of the
chimney & encircles in its descent the side openings. The shade or covering is
carried by side arms, attached to the ring or top piece, or by other suitable means;
this is another mode of providing a Cap or Cover for the purpose specified in my
aforesaid Provisional Specification.
-
It may be so arranged that the air supply to the burner of the Lamp herein-
before described shall all pass through the heating apparatus, or partly through it
and partly in the ordinary way.
