PROVISIONAL SPECIFICATION.
Improvements in Burners for the Combustion of Gas.
We ALFRED RICHARD SENNETT, Civil Engineer & ROBERT LAVENDER,
Manufacturing Chemist both of Brentford, Middlesex do hereby declare the
nature of this invention to be as follows:-
Our burner consists essentially of a chamber terminating in an annular aperture
at the top through which the gas issues and is there ignited, air passing up to the
interior of the flame as is usual in burners of the Argand type, in combination with
an outer cap or casing which extends above & around the aforesaid chamber, thereby
forming a space which we call the combustion chamber.
This outer cap or casing we generally make hollow and cause the gas to pass
through it, (generally traversing passages formed therein) on its way to the burner.
Heat produced by the flame is communicated to the said outer cap or casing and
heats both the gas and air prior to combustion. In some cases we insert a tube or
chamber forming an upward prolongation of the central air passage for the purpose
of carrying air to the upper portions of the flame.
Dated this 8th day of January 1891.

COMPLETE SPECIFICATION.
Improvements in Burners for the Combustion of Gas.
We ALFRED RICHARD SENNETT Civil Engineer and ROBERT LAVENDER
Manufacturing Chemist both of Brentford in the County of Middlesex 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 consists essentially of a gas burner on the Argand system in which
the warming of the gas and air prior to combustion is attained in a very simple &
effective manner.
In the figure, which represents a section of the whole contrivance the gas passes
from supply pipe A into the hollow space C of cap F whence it issues by pipe or
pipes H. The gas is guided by conical baffic plates M & N through the narrow
passage O into burner proper and is ignited at annular orifice K. The conical
cap L and baffle plates are screwed to or otherwise attached to inner wall B so that
the annular orifice K is adjustable in width. The cap F can be furnished with
spiral passages or other contrivances for delaying the passage of gas through it.
Heat radiating from lighted gas warms the gas prior to combustion, and also
air passing up to exterior of flame in the way common to burners of the Argand
type.
Outside of cap F may
be placed a cap G, which should be bright externally to
prevent the passage of heat from F. It is desirable also to fill up the inter-
vening space between F and G with some non-conducting substance.
Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed we declare that what we
claim is.
1. A gas burner in which the central burner is surrounded by a hollow cap F
& in the hollow space of which the gas flows in order to be heated prior to
combustion.

page_text: 2. In combination with the contrivance covered in Claim 1, the cap G with or
without packing for preventing the escape of heat from cap F.
