ARDEN HILL Gas Engineer 14 16 18 Constitution Hill Birmingham County of
Warwick do hereby declare the nature of this invention to be as follows:-
The addition of a plate or plates of iron (or other suitable material) to any boiling
or grilling burner of a gas cooking stove in such manner that by a simple mechanical
movement these plates or plate of iron (or other suitable material) may be raised or
lowered above or below the flames of any such burner so that the heat of such flames
shall be controlled and reflected upwards or downwards as desired-Further the
addition and combination with a gas cooking stove of a loose or fixed fire chamber
arranged to burn coke having a gas burner connected therewith for playing or burning
a gas flame amongst the coke for the purpose of lighting and assisting the burning
of same.

page_text: I, ARDEN HILL of 14 Constitution Hill, Birmingham in the County of Warwick,
Manufacturer, 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 has reference to gas cooking stove burners, principally of the kind
commonly called grillers, in which the flame deflection of a barrel or other burner, is
controlled by the change of position of certain movable plates, so as to bring the flame
of the burner, above or below them, for boiling, or for grilling purposes.
My invention consists in means for working the said plates, so as to thereby change
the flames impingement.
1
Figure represents in transverse vertical section, a gas cooking stove, constructed
according to one form of my invention, the heat deflection plates of which, are
represented in their lowered positions, and with the burner flame or flames, directed
upon their top sides, for boiling purposes.
Figure 2 represents the same as figure 1, but with the plates raised, and with the
flame, or flames of the burner, directed and playing upon the undersides of the plates,
and in which position, the stove is used as a griller, or as a cooker, as the heat given
off from the burners, is conducted through the plates, and also radiated downwards,
upon objects to be cooked, which are placed thereunder.
Figure 3 represents a plan of an end of one of the plates, and with the guide snugs
lying within slots made in the stove end.
The same letters of reference indicate corresponding parts in figures 1, 2 and 3.
a is the body of the stove, pierced with an elongated opening a', made through the
top a³ thereof.
b is a barrel burner, running under, and in the middle of the said
opening, and with opposite jets 63, directed outwardly on its two opposite sides; so
that the flame, or flames emitted therefrom, are directed alternately upon the top and
undersides of movable plates c, c, which rise and fall by their snug ends c³, best seen
in figure 3, working within slots a*, a*, made within the two opposite ends of the stove.
The inside edges of the plates, run and lie parallel to the two opposite sides of the
burner; so that on the plates being in a position as represented in figure 1, the flame
jets, are directed upon the top sides of the plates; when in this position, the stove is
used for boiling purposes, and when raised in the position figure 2, the stove is used
for cooking or grilling purposes, as the opposite flame jets of the burner, are made to
impinge upon their undersides, and play among long or extended teits or spikes d,
depending or hanging therefrom.
The plates are also pierced with a series of holes c³, intervening between the long
teits or spikes; so that when the heat deflector plates are in the position as in figure 2,
the heat is conducted both upwardly through the plates, and radiated downwards,
upon objects placed thereunder, to be cooked.

to raise
The plates are raised, by jointed arms or levers e, e, working in unison with each
other, and connected and jointed to end framings e³, carried by a puller bar e, common
to them both; so that the pulling outwards of the said bar e³, from the position as
represented in figure 1, causes the top curved ends of the said jointed levers
the plates, and hold them in their grilling positions, as represented in figure 2.
To lower the plates, press inwards the bar e, in the direction indicated by the
arrow, when the levers are taken from under the plates, and they fall by their own
weight into the positions as represented in figure 1, with the flame jets of the burner,
directed upon their top sides.
Instead of jointed levers, inclined snugs or inclined planes, carried by the frame e³,
may be made to raise and lower the plates, by its pulling outwards, and pushing
inwards, by a pull bar.
Or the jointed levers may be worked by a handle, which is secured to the middle of
a connecting link, whose outer ends are jointed to the lower ends of the jointed levers ;
so that on the turning of the handle, the plates are raised or lowered.
It will be understood, that the plates are worked by levers or snugs, in duplicate,
situated respectively at the two opposite ends of the stove, and which levers or snugs
are carried by a frame common to them all; so that on the frame being reciprocated,
the whole of the levers or snugs, are worked together, and the plates raised or lowered
evenly, at two opposite points, without any tendency to jamb.
Figure 4 represents a longitudinal vertical section of another form of my invention,
in which the plates are jointed at their outer ends, instead of with their ends being
raised, lowered and guided within slots. Figure 5 is a plan of the same, and figure 6
is a transverse vertical section upon the dotted lines A B figure 5, and with the inner
ends of the plates lowered to a position below the flame jets of the burner for boiling ;
so that the said flames are directed upon the tops of the plates, which radiate the flame
or flames, and heat upwards, and is used, as aforestated, for boiling purposes.
Figure 7 represents the same section as figure 6, with the plates raised, or placed
in a horizontal position, and with the burner jets, directed under the said plates, and
among the depending teits or spikes, disposed on their undersides.
The same letters of reference indicate corresponding parts in figures 4, 5, 6 and 7.
a is the body of the stove, b is the burner, directed under, and in the middle of the
opening a², in the top a³, of the stove. c, c, are deflector plates, hinged at their
outside ends at c², and with long teits or spikes d, depending on their undersides.
e, e, are jointed levers, jointed and connected to the puller bar e³. In this case, the
levers e, are not in duplicate, as in the preceding arrangement.
Thus, the pressing inwards of the puller bar e, takes the parts into the positions, as
represented in figure 6, and with the plates inclining downwards and inwards from the
fulcrum centres upon which they turn.
The pulling outwards in the reverse direction, turns the levers upon their joint
centres, and raises the plates horizontally into the positions as represented in figure 7.
The motion of the levers, is limited by a stop f
Figure 8 represents a modification of the last form of my invention. In this
arrangement, the plates c, c are raised and lowered upon their joint centres c³, by
incline planes or snugs e, carried by the operating draw bar e³; so that the moving
inwards and outwards of the said draw bar, raises the plates into a horizontal position,
or allows them to fall by gravity into inclined positions.
The plates have upon their undersides, depending webs c³, preferably carrying
anti-friction rollers c, so as to reduce the friction of the plates, upon the inclines. In
this stove, two burners are represented at the opposite ends of the plates, instead of
employing a single burner between the plates.
The pull har for operating the plates, may be provided with rack teeth upon its
upper side, which engage with like rack teeth, carried upon the curved underside of
the webs, carried by the plates; so that the reciprocation of the bar, gives the
necessary rising and falling motion to the plates, by the teeth of the one, engaging
with the teeth of the other.

page_text: Limiting stops are provided for determining the distance of the throw, or the
rising and falling of the plates.
I wish it to be understood, that the plates and burner may be duplicated to any
number required.
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 :-
First. Converting cooking stove burners, into either grilling or boiling burners,
by the use of flame and heat deflector plates, which are made to rise vertically above,
or fall vertically below the flame jets, of a burner, substantially as described and set
forth in figures 1 and 2.
Secondly. Making the ends, or the lug ends c³, of rising and falling heat and
flame deflector plates c, work within slots or gaps, made within the two opposite sides
of the walls of the stove; whether the said plates c be disposed horizontally or
inclined, as set forth in figures 1 and 2.
Thirdly. Mounting heat, and flame deflector plates, or the outer opposite sides, or
ends thereof, upon pivots or joint centres, or their equivalents, substantially as
described and set forth in figures 4, 5, 6 and 7.
Fourthly. Making the flame and heat deflector plates, of cooking stoves, when in
their boiling positions, incline downwards, and inwards, substantially as set forth in
figures 4, 5, 6 and 7.
Fifthly. Providing heat and flame deflector plates, with long teit or spike like
extensions, depending from their undersides, substantially as described and set forth
in figures 1 to 7 both inclusive of the accompanying drawings.
Sixthly. Raising and lowering, or placing in position or positions, the flame and
heat deflector plates of cooking stoves, by means of jointed arms or levers, connected
and jointed to a frame or pull bar, or to a link, or links, connected with a handle,
substantially as described and set forth, in figures 1 to 7 both inclusive of the
drawings.
Seventhly Raising or lowering into position, either for grilling or boiling purposes,
the flame and heat deflector plates of cooking stoves, by means of inclines, or snugs,
carried by a pull and pushing in bar or frame, whether the said inclines on the bar or
bars be toothed or plain, substantially as described and set forth in figure 8.
Lastly. The general construction and arrangement of the parts of cooking stoves,
as herein described and set forth in the several figures of the drawings.
Dated this Nineteenth day of Sentember 1887.
