We, JOHN FREDERIC WRIGHT and GEORGE ERNEST WRIGHT, of the firm of John
Wright & Co., of Essex Works, Thimble Mill Lane, Aston, Warwickshire, Gas
Engineers, 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:-
The principal object of this invention is to provide improved means whereby the
flame or flames of an atmospheric gas burner or burners can as desired either be
directed against and caused to heat a deflector, for the purpose of toasting grilling or
otherwise cooking something placed beneath the deflector, or directed away from the
deflector and caused to form a powerful flame or flames for boiling or cooking some-
thing placed above.
In order that our said invention may be the better understood and carried into
practice we will describe the same by referring to the Figures on the accompanying
drawings of which Fig. 1 represents in sectional side elevation and Fig. 2 in plan a
pair of gas burners, deflector and parts connected therewith arranged according to
our invention and illustrating how the gas flames are directed against the deflector
Figs. 3 and 4 represent the same parts as Figs. 1 and 2 and shew how the flames are
directed away from the deflector for boiling or heating something placed above;
Fig. 5 is a sectional front elevation of the same and Figs. 6, 7 and 8 illustrate details
of the same as hereinafter set forth.
The same letters of reference indicate the same parts in all the Figures.
A¹ A are two tubular atmospheric gas burners by preference of the kind described
in the Specification of our Letters Patent No. 13,248 or other atmospheric gas
burners.may be employed, the usual fittings being provided at the inlet ends a¹ a',
and the outlet orifices a³ a being arranged to point towards each other. These
burners are carried by the cross bars B B or are otherwise suitably supported.
Between the outlet orifices of the gas burners we provide the deflector which is
situated a certain distance from each so as to leave two open spaces d'd' for the
Blames from the burner. The said deflector by preference consists of two sets of cast
ron bars (the bars in one set are marked C and the bars in the other set (*) leaving
an open space e between each set. Each of these bars has downwardly projecting
spikes c on its underside the object of which is to increase the heating surface of the
LD .
;

page_text: deflector. One of these bars is shown separately in elevation and inverted plan by
Fig. 6. The ends of the bars are supported by a suitable frame F, shewn separately
by Fig. 8. Immediately above the deflector is a baffle plate G (shewn separately by
Fig. 7) arranged to slide to and fro on the frame F. This plate G has a central
opening of the same size as the deflector thus leaving two bars g¹g of the same
width as the open spaces d' d' and at each side is a projecting pip / which by
engaging in slots formed by the guide bars i and the top of the frame F prevent the
plate rising or moving too far to or fro. At the front of the plate G is a handle g³ by
which it can be moved along the top of the frame F.
The operation of the parts above described is as follows:-If it is required to toast,
grill or otherwise cook or heat something beneath the deflector the openings d¹ d² are
closed by moving the baffle plate G to the position shewn by Figs. 1 and 2 when as
the gas flames cannot rise through the openings dd, they are drawn by the ascending
air underneath the deflector and between the spikes c to the central opening e in the
deflector, as shewn by the arrows, thus causing the bars ("C" of the deflector to
become intensely hot so as to toast, grill or otherwise cook or heat anything placed
beneath. When the baffle plate G is slid along the top of the frame F so as to open
the openings dd, as represented by Figs. 3 and 4, the flames from the gas burners
will rise up through those openings as indicated by the arrows so as to boil or other-
wise heat any vessel placed above, and the deflector will be comparatively cool.
The accompanying drawings illustrate what is considered to be the best way for
carrying our said invention into effect but it is to be understood that the invention is
not limited to the precise details illustrated as for instance the deflector may be made
in a piece instead of being formed in separate bars; or instead of employing a duplex
apparatus as illustrated, a single gas burner and one half only say Cf of the deflector
and one sliding bar g' and corresponding opening d may be used; or when a larger
heating surface is required three or more gas burners may be similarly arranged
with corresponding sections of deflector and bars of the baffle plate.
The upper surfaces of the baffle plate G and bars C¹ C² are shewn corrugated on
the drawings so as to increase their heating surfaces and give them an ornamental
appearance but this is merely a matter of design and forms no part of the invention.
Having now particularly described and ascertained the nature of our said Invention>
and in what manner the same is to be performed, we declare that what we claim is :
1st. The combination with a gas burner for boiling grilling toasting and other
like purposes, of a deflector and sliding baffle plate so arranged relatively to the gas
burner and to each other that by moving the baffle plate the gas flame can either be
caused to heat the deflector or to have an unobstructed passage upwards substantially
as herein before described.
2nd. The combination with a pair of gas burners for boiling grilling toasting and
other like purposes, of a deflector arranged between the said burners and a baffle
plate arranged to slide across the deflector, a space being left between each side of
the deflector and the adjacent burner, and the baffle plate being arranged so as either
to cover the said spaces and cause the gas flames to heat the deflector or to uncover
the said spaces and allow the gas flames to have unobstructed passages upwards
therethrough, substantially as herein before described and illustrated by the accom-
panying drawings.
3rd. The arrangement and combination of the gas burners, deflector, baffle plate
and frame as herein before described and illustrated by the accompanying drawings.
