Specification Accepted, 9th Nov.. 1888
We, JOHN MARRIOTT WILKINSON, of the Park, Lincoln, in the County of Lincoln,
Ironmonger, and GEORGE UPTON, of Corn Hill, Lincoln, aforesaid, Butcher, 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 :-
This invention of improvements in or relating to gas burners has reference more
particularly to those burners known as Bray's burners in which the gas issues through
two small holes a short distance apart in the top of the burner; and the object of our
invention is to more thoroughly consume the gas and obtain a better light by arranging
for a current or currents of hot air to impinge upon the flame.
We will describe our invention by referring to the accompanying drawing of which
Fig. 1 represents in front elevation a Bray's burner with our invention applied; Fig. 2
is a longitudinal section of the same and Fig. 3 is a plan of the same; Fig. 4 shows
our invention in plan and sectional elevation separate from the burner.
a is the Bray's burner and b 6' are the two small holes in the top through which
the gas issues. In carrying out our invention we employ a short tubular piece
marked c which fits on to and surrounds the upper part of the burner.
Fixed to this
tubular piece c is a cross bar d which fits on to the top of the burner between the two
sinall holes therein and at each side of the cross bar d there is a corrugation e formed
in the tubular piece c so as to leave an air space at each side of the burner. When
the gas is lighted the flame is partly divided by the cross bar d and the air rushes up
the spaces e between the burner and the tubular piece cand as the burner soon becomes
hot this air is heated and as it impinges on the flame it facilitates combustion and
increases the light.
The tubular piece c with its cross bar d is by preference made in three parts as
shown more particularly by Fig. 4 the cross bar having two downwardly projecting
fangs d' which are embraced between the two halves of the tubular piece c the
longitudinal edges of one of the halves of the tubular piece c being folded over the
edges of the other half so as to secure the two halves together and the cross bar d
between them.

page_text: Our invention is also applicable to that kind of burner which is provided with a
cross bar such as shewn by Figs. 5, 6 7 and 8 of which Fig. 5 is a front elevation of
a gas burner of this kind with our invention applied. Fig. 6 is a longitudinal sectional
elevation of the same; Fig. 7 is a plan of the same and Fig. 8 shews the tubular
piece separately. In applying our invention to this kind of gas burner (marked f)
which is provided with a cross bar (marked f¹) we dispense with the cross bar d on
the tubular piece c and make the tubular piece by preference as shewn more particu-
larly by Fig. 8, the passages e e between the burner and the tubular casing supplying
air to the flame in a similar manner to that above described with reference to
Figs. 1, 2, 3 and 4.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1st. The combination with a Bray's or other like two hole gas burner, of a
cross bar d above and between the said two holes and the air passages e e at the
sides of the cross bar for supplying heated air to the flame, substantially as herein-
before set forth.
2nd. The tubular piece c adapted to fit on to a Bray's or other like two hole gas
burner provided with grooves e e and a cross bar d for the purposes and substantially
as hereinbefore described and illustrated by Figs. 1, 2, 3 and 4 of the accompanying
drawing.
3rd. The tubular piece c adapted to fit on to a burner provided with a cross
bar, and furnished with grooves e e for the purpose and substantially as herein-
before described and illustrated by Figs. 3, 5, 6, 7 and 8 of the accompanying
drawing.
