IMPROVEMENTS IN GAS BURNERS
Year: 1885

page_text: I, JAMES LEWIS of 153 Brockley Road Brockley in the County of Surrey
Engineer do hereby declare the nature of my invention for "IMPROVEMENTS IN
GAS BURNERS," to be as follows:-
This Invention relates to improvements in fish-tail bats-wing and other similar
gas burners.
For this purpose according to my invention I surround the top of a gas burner
of the above description with a tubular ring the gas jets being arranged a short
distance below the top edge of such tubular ring.
The depth of the tubular ring around the gas burner will depend upon the size
or "number" of the gas burner.
The tubular ring may either form part of the burner or it may consist of a short
tube slid over the burner or screwed or otherwise combined therewith and may if
desired be adjustable thereon.

Engineer do hereby declare the nature of my invention for "IMPROVEMENTS IN
GAS BURNERS" and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement:-
This Invention relates to improvements in fish-tail bats wing and other similar
gas burners by which the illuminating power of the gas consumed thereby is
increased.
For this purpose according to my invention I surround the top of a gas burner
of the above description with a tubular ring the gas jets being arranged a short
distance below the top edge of such tubular ring.
The depth of the tubular ring around the gas burner will depend upon the size
or number of the gas burner.
if
The tubular ring may either form part of the burner or it may consist of a short
tube slid over the burner or screwed or otherwise combined therewith and
desired be adjustable thereon.
may
And in order that my invention may be more clearly understood and readily
carried into practice I will proceed to describe the drawings hereto annexed.
DESCRIPTION OF THE DRAWINGS.
Figures 1 show a side view section and plan drawn to an enlarged scale of an
ordinary gas burner having my improvement applied thereto.
a is a tubular ring or collar which is slid over the gas burner 6 the upper edge
of the ring a projecting a short distance above the gas jets which impinge against
the inner surface of the ring. The height of the ring a above the top of the gas
jets of the burner 6 can be adjusted so as to obtain the best results or the height
of the ring may be determined by the lower end coming against a fixed stop on
the burner. If desired the ring or collar a may be arranged to screw on to the
burner by which its height above the gas jets can be adjusted.
In order to obtain a flame of more uniform shape than that produced by the
application of the ring or collar a shown in Figures 1 I find it advantageous to turn
the top or upper edge of the ring a slightly over inwards as represented by
Figures 2 of the drawings which are similar views to those shown by Figures 1.
And in order to obtain a long clear flame from small burners for street lighting or
other purposes I turn the top or upper edge of the ring or collar a over to a greater
extent as represented in Figures 3.
Figures show my improvements applied to an ordinary bats-wing gas burner
the top or upper edge of the ring or collar a being arranged on a level with the
curve or top of the burner b.
Figures 5 show a similar bats-wing burner the top or upper edge of the ring or
collar a being turned over inwards and having slots cut out of it opposite to the
slit in the burner extending nearly to the tubular part of the ring or collar a.

page_text: In Figures 6 the movable ring or collar a is dispensed with the steatite or part
of the burner pierced with the gas jet holes being fixed at a suitable distance
below the upper edge of the metal case of the burner b.
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
The arrangement and application of a ring or collar a to fish-tail bats-wing or
other similar gas burners for the purpose of increasing the illuminating power of
the gas consumed thereby substantially as described and illustrated by the
drawings hereto annexed.
