Improvements in Grillers or Gas Cooking Stoves.
I, JOSEPH SYKES WOOD, of Vine Cottage, back of No. 214 Lichfield Road,
Aston, near the City of Birmingham, Manager of Works, do hereby declare the
nature of this invention to be as follows:-
This invention relates to gas cooking stoves of the type commonly called
"grillere," and has for one of its objects the reduction of the cost of manu-
facture of the stoves, another object, the making of the parts detachable for the
purposes of re-fitting, and for another object, the simplification of the said parts.
According to my invention, the griller or heat-deflection plates, which are
situated upon the two opposite sides of the tabular burner, are raised and lowered,
or elevated above and depressed below the jets issuing from the burner, by giving
a longitudinal traverse to the same, that is to say, the griller or heat deflection
plates, which have inclined planes at one end, and aleigh fronts taking upon like
inclined planes supported by the body of griller framing at the other end, are
respectively lifted and lowered above and below the flame jets of the burner by
sliding the said heat-deflection plates to and fro.
In carrying out one form of my invention, I take an ordinary oven or other shaped
body part, with an open top, preferably crossed bridge-wise by a tubular burner
suitably connected and fitted."
Located upon the two opposite sides of the said burner, and coming upon
shelf or other rests disposed upon the opposite sides of the said open top, are
two or other number of coupled-together griller or other heat deflection plates,
with their one ends formed into inclined planes terminated by straight rests, which
rests are preferably coupled together by an inverted bridge connection.
The other extreme ends of the plates may be turned up, sleigh-runner-front-wise,
or inclined, whilst the plain parts at the junction of the said turned up ends with the
plate bodies, come upon rest brackets having upwardly inclined planes coming
forward of them.
The plates work within suitable guides and are provided with stops to insure
and limit their proper to and fro movements.
The inclines of both ends of the plates are the same, so that the coupled-together
plates rise and fall in a parallel movement.
Assuming that the jets from the burner are above the tops of the plates when the
same are in their lowered positions, then the same are made to play over the plates
and are used for boiling purposes or for heating ordinary culinary utensils, but to
convert the stove into a griller, simply push forward the plates, when the fore parts
travel up the inclined planes carried by the stove framing, whilst their rear inclined
parts likewise move up the plain bearing, thus parallelly lifting the said plates to
such a position that the jets of the burner are made to play thereunder, either for
grilling purposes or for deflecting the heat downwards upon alimentary articles to
be cooked placed within the oren.
The griller plates may be provided with ordinary depending spikes, fins or teats,
and instead of the inclined flames being carried upon one side of the stove frame and
the other ends of the griller plates, they may be upon both ends of the plates and
made to take their bearings upon, and work over plain parts of the framing, one of
which is preferably elevated higher than the other so as to ensure the perfect
parallelism of the movement.

page_text: The traverse of the plate may be effected by a lever, jointed at its end and
being provided with a short arm or arms which take or takes through a suitable
opening or openings in one or both of the plates, so that on the lever being moved
the plates are traversed and raised or lowered, according to the direction of the
movement.

Improvements in Grillers or Gas Cooking Stoves.
I, JOSEPH SYKES WOOD, of Vine Cottage, back of No. 214 Lichfield Road,
Aston, near the City of Birmingham, Manager of Works, do hereby declare the
nature of this invention and in what manner the same is to be performed, to he
particularly described and ascertained in and by the following statement :—
This invention relates to gas cooking stoves of the type commonly called
"grillers," and has for one of its objects the reduction of the cost of manufacture
of the stoves and for another object, the making up of the stove of easily detached
and fitted loose parts that can be readily put together.
According to my invention, the griller or heat-deflection plate, which is surrounded
by the tubular burner, is raised and lowered, or brought above or below the jets
issuing from the burner, by giving a longitudinal traverse to the same, that is to say,
the griller or heat deflection plate, which bas an inclined plane at one end, and comes
upon a like inclined plane supported by the body of griller framing at the other end,
is lifted and lowered above and below the flame jets of the burner by sliding the
said beat-deflection plate to and fro.
In carrying out one form of my invention, I take an ordinary oven or other shaped
body part, with a partly open top, preferably crossed by a tubular burner suitably
connected and fitted.
Located between the sides of the said burner, and coming upon shelf or other
rests disposed upon the opposite sides of the said open top, is a griller or other
beat deflection plate, with one end formed into an inclined plane terminated by a
straight rest.
The other extreme end of the plate may be either straight or have a slight
inclined lead, and come upon a rest bracket having an upwardly inclined plaue
coming forward of it.
The plate may work within suitable guides and is provided with stops to insure
and limit its proper to and fro movement.
The incline of the griller plate corresponds to the incline of the fixed bracket
carried by the buruer or body part.
Assuming that the jets from the burner come above the plane of the top of the
plate when the same is in its lowered position, then the same play over the plate
and are used for boiling purposes or for heating ordinary culinary utensils, but to
convert the stove into a griller, simply push forward the plate, when its fore part
travels up the inclined plane carried by the stove framing and always remains
horizontal, whilst its rear inclined part likewise moves up the plain bearing, thus
the said plate is parallelly lifted to such a position that the jets of the burner are
made to play thereunder, either for grilling purposes or for deflecting the heat
downwards upon alimentary substances to be cooked placed within the oven.
The griller plates may be provided with ordinary depending spikes, fins
or teate.
Figure 1 of the accompanying drawing represents a longitudinal vertical section

page_text: of a griller stove made or provided with improvements according to my invention..
In this view the griller plate is shown lowered below the jet holes of the
burner, or in the position which it takes when [the stove is in use for boiling
purposes.
Figure 2 represents a like seational view as Figure 1, but with the griller
plate moved forward, and through the agency of the inclined planes upon plate
and stove respectively, raised above the jet holes of a burner, so as to make
the said jets play upon the underside of the plates, in which position the stove is
used for grilling.
Figure 3 represents a topside plan and Figure 4 an edge view of the griller plate
separately.
:
Figure 5 is a topside plan of Figure 1 with the upper or rest part removed and
Figure 6 is a like plan view of Figure 2.
The same letters of reference indicate corresponding parts. in Figures 1 to 6 of
the drawings.
a is the body of the stove or griller and a' is the detachable upper part having
bar-shaped rest-lifts a³, standing above the same, whilst an aperture a³ is formed
in the middle part wherethrough the flame or radiated heat upwardly passes
either for boiling or grilling purposes.
Located within the upper part of the said body and coming a little below the
top is a tubular burner b, having jet holes b', directed above the plane of the
traversing griller plate c, when lowered. The outer end o', of the said griller plate
rests, when in the said lowered position upon a shelf rest d', of a fixed and upwardly
directed inclined plane d", surmounted by a straight rest d, upon which latter the
said end c, comes when in its elevated position.
The other and inner end c², which rests upon a fixed cross bar e, of the frame a
when in the positions shown in Figures 1 and 5) has a downwardly inclined
plane, terminated by a plain rest, a stop c, and a pull and push bar cª.
The rest part e, of the bar e, slides upon the part a*, of the end wall of the
body part a.
By pushing the pull and push bar e, forwardly when the plate is in the position
Figure 1 the plate is traversed forwards, and by the inclined plaues is elevated
and rests in a plane above the jets of the burner as represented in Figures 2
and 6.
Figure 7 represents a modified form of my invention, in which both the inclined
planes are formed with the griller plate, instead of one being in the griller plate
and one in the stove as in the previous arrangement.
a is the stove body, a' the loose top, a the bars or lifts and a³ the central
opening. b is the burner with jet holes b', and c is the griller plate, with inclined
planes c, e, formed at its outer and inner ends, and with each end respectively
having pairs of rest parts c², c', which alternately come and rest upon brackets or
baisande, according as to whether the stove is in use for grilling or for b.iling
purposes. is a stop for limiting the back movement of the griller plate, whilst
the stop limits the forward movement. c is the pull and push bar for giving
the traversing movement to the griller plate.
By reciprocating the said plate to and fro, the same is made to rise, descend and
rest above or below the plane of the jet holes of the burner according as to
whether the stove is to be used for grilling or boiling purposes.
Although I have shown that the griller plate is traversed through the medium
of a pull and push bar, yet 1 wish it to be understood that the said traversing may
be effected by a jointed arm operated by a lever or handle.
Having now particularly described and ascertained the nature of my sail inven-
tion, and in what manne: the same is to be performed, I declare that what I
claim is :-
First. In griller stoves, changing or converting the same from a griller to a
boiler or vice versa through the medium of a sliding griller plate, raised and

page_text: lowered with a horizontal movement by inclined planes on plate and stove body
framing respectively.
Secondly. In griller stoves, raising and lowering the griller plate for converting
the stove from a griller to a boiler or vice versa, and keeping the said plate in
position when raised and lowered, by inclined planes with rests, arranged and
combined substantially as described and set forth in Figures 1 to 6.
Thirdly. In griller stoves, raising and lowering the griller plate for converting
the stove from a griller to a boiler or vice versa, and keeping the said plates in
position when raised and lowered, by inclined planes with rests arranged and
combined substantially as described and set forth in Figure 7.
Dated this 26th day of November 1895.
