Improvements in Gas Grillers or Grilling Stoves.
I, WILLIAM COULSON PARKINSON, trading as W. Parkinson and Company, of
Bell Barn Road, in the City of Birmingham, Manufacturer, do hereby declare the
nature of this invention to be as follows:-
This invention relates to gas apparatus or stoves technically known as grillers,
and consists of an erection provided with burners which are caused to play upon the
undersides of pierced or perforated plates, suitably mounted that the same admit of
being placed in positions for the operation of grilling, or for use as a means of
boiling.
Thus, when the plates are down, the worked flames of the burners play directly
or nearly so upon the vessel containing liquid to be boiled or heated, whilst when
the said plates are in a horizontal plane, the gas jets are made to play upon the
undersides of them, which become heated.
In my invention, the griller plates are mounted wing fashion, that is, the opposed
inner edges of the plates come together and are there jointed whilst the outward
side portions turn downwards flap-wise when the stove is required to be employed
as a boiler, but when employed as a griller, the wing plates are lifted and stayed in
a horizontal position.
The releasing and lifting is performed by a pull and push rod.
In carrying out my invention, I take a rectangular box erection, open at bottom,
supported upon feet, and having the middle of the top also open. The erection is
preferably enclosed upon three sides, whilst the burners consist of a tubular frame,
crossing the open space at the top, but lying some little distance below the plane of
the top framework. The tubes of these tubular burners form the opposite sides to
the burner frame, whilst the off-side end is made by a cross-piece. The entrance
to the burner is tubular, so that the sides form as it were branches enclosing an
elongated rectangular shaped space, with the jet holes directed horizontally from
the inside edges of the sides, so that when the griller plates are horizontal, the
flames play upon teats or hanging spikes upon their undersides, hence the efficient
heating of the same, but when the plates incline downwards alike unto the roof
of a house, the said flame jets are projected upon the top sides of the griller
plates.
The flaps or griller plates turn upon common end centres of pivots carried by one
of the said plates.
The plates of the wing griller are lifted by jointed crank arms coming upon the
undersides of them, and with the ends of the said arms which are directed upwardly,
coming upon the offside undersides of the said plates.
Working within guides upon, the inside of the frame, and in the direction of, and
adjacent to, the cranked arms, is pull and push bar, rod or equivalent, having a
handle at front and outstanding or horizontally directed hook shaped branches,
between the gaps of which, the shanks of the crank arms come. When the wing
plates are in position for boiling, the ends of the cranked arms are clear of the
undersides of the plates, which fall by their own weight. The picking up of
the plates is performed by pushing in the pull and push bar, which turn the
crank arms upon their joint centres, and bring their terminal and cranked ends
upwards or nearly so, thereby lifting the plates, and locking them in a horizontal
position.

page_text: The sliding of the pull and push bar outwards takes the cranked arms out of
position from under the plates which then fall.
The pull and push bar is horizontally gapped and slotted, which take and slide
upon shelf snugs as guides.
To facilitate attachment and detachment of the flaps, the bearing centre upon
one end of the frame is made continuous whilst the other is gapped.
Sliding over the griller plates is a fret plate, or a reticulated or open work plate,
operated by a pull and push rod or handle.
It may be observed that the picking up of the plates is created by the pressure
or impingement of the branches of the pull and push rod against the branches of 1
the cranked arms or jointed bell cranked arms.

Improvements in Gas Grillers or Grilling Stoves.
I, WILLIAM COULSON PARKINSON trading as W. Parkinson and Company,
of Bell Barn Road, in the City of Birmingham, 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 relates to gas apparatus or stoves technically known as grillers,
and consists of an erection provided with burners, the flames proceeding from
which are caused to play upon the undersides of pierced or perforated plates, so
mounted that the same admit of being placed in one position for the operations of
grilling or cooking, and placed in another position for the operation of boiling.
Thus, when the plates are down, the naked flames of the burners play directly
or nearly so upon the underside of a vessel containing liquid to be boiled or heated,
whilst when the said plates are in a horizontal plane, the gas jets are made to play
upon the undersides of them, and the said plates become heated, and when in this
position, the apparatus is used as a griller or as a cooker.
In my invention, the griller plates are mounted wing-fashion, that is, the opposed
inner edges of the plates come together and are there jointed, whilst the outward
side portions turn downwards flap-wise when the stove is required to be employed
as a boiler, but when employed as a griller, the wing plates are lifted and stayed in
a horizontal position.
The releasing and lifting is performed by a pull and push rod.
In carrying out my invention, I take a rectangular box erection, open at bottom,
supported upon feet, and having the middle of the top also open. The erection is
preferably enclosed upon three sides, whilst the burners consist of a tubular frame,
crossing the open space at the top, but lying some little distance below the plane
of the top framework. The tubes of these tubular burners form the opposite
sides to the burner frame, whilst the off-side end is made by a cross-piece. The
entrance to the burner is tubular, so that the sides form as it were branches
enclosing an elongated rectangular shaped space, with the jet holes directed
horizontally from the inside edges of the sides, so that when the griller plates are
horizontal, the flames play upon teats or hanging spikes upon their undersides,
hence the efficient heating of the same, but when the plates incline downwards
alike unto the roof of a house, the said flame jets are projected upon the top sides
of the griller plates.
One of the griller plates turn upon end centres or pivots of the other, griller

page_text: plate while the ends of the said pivots rest and turn in bearings in the ends of the
burner.
The plates of the wing griller are lifted by jointed and cranked arms acting
upon the undersides of the plates and worked by a pull-push slide working within
guides:
When
Thus working within guides upon the inside of the frame, and in the direction
of, and adjacent to, the cranked arms, is a pull and push bar, rod, slide or equivalent,
having a handle at front and outstanding or horizontally-directed hook-shaped
branches, between the gaps of which the shanks of the crank arms come.
the wing plates are in position for boiling, the ends of the cranked arms are clear
of the undersides of the plates, which fall by their own weight. The picking up
of the plates is performed by pushing in the pull and push bar, which turns the
crank arms upon their joint centres, and bring their terminal and cranked ends
upwards or nearly so, thereby lifting the plates, and locking them in a horizontal
position.
The sliding of the pull and push bar outwards takes the cranked arms out of
position from under the plates, which then fall.
The pull and push bar is horizontally slotted, which slot takes and slides upon
shelf snugs as guides.
To facilitate attachment and detachment of the flaps, the bearing centre upon
one end of the frame is closed whilst the other is gapped or open.
It may be observed that the picking up of the plates is created by the pressure
or impingement of the branches of the pull and push rod against the branches of
the cranked arms or jointed bell-cranked arms.
Figure 1 of the accompanying drawings represents partly in plan and partly in
horizontal section, the underside of a grilling stove or gas griller constructed,
arranged and fitted with improvements made according to my invention.
Figure 2 represents a transverse section upon the dotted line x Figure 1, of a
middle portion of the said griller or stove, showing the jointing and mounting of
the winged griller plates to each other and to the ends of the burner.
Figure 3 represents a transverse vertical section of the said griller Figure 1 upon
the dotted lines A B, with the loose bars removed, and which said view shows the
winged griller in a grilling position.
Figure 4 shows a like sectional view as Figure 3, but upon the dotted lines CD
Figure aud with the pull and push slide or bar drawn outwards, and the
griller plates dropped to admit of the flame of the stove being used for boiling
purposes.
The same letters of reference indicate corresponding parts in the several figures
of the drawings.
a is the frame of the stove, supported upon feet a³, and having an open bottom a³,
and also an open top a', fitted with a tubular boundary burner b, situated at a lower
plane than the said open top at, and forming as it were, a rectangular shaped frame
to the griller aperture a, wherein are located and mounted winged griller
plates c, c. The griller plate c, has an end pivot c³, which takes through a knuckle
or joint c, at the inside end of the griller plate c', whilst the plate c¹ has a pivot co,
taking through a like knuckle joint c', at the inside end of the plate c and with the
extreme ends of the said pivots c³, c, taking within bearings 6, 6, (the former of
which is open topped) formed respectively within the end, of the tubular
burner b, and the framing part 63, thereof. The jet holes 6, of the burner b, are
directed horizontally so that the flames play upon hanging teats upon the undersides
of the griller plates (see Figure 3), when the same are in a horizontal plane, but
when the griller plates are down, as in Figure 4, then the flame jets have a clearance
above the tops of the griller plates and play directly through the bars (not shown)
and upon
the underside of a vessel to be heated. These wing mounted griller plates
are lifted by or through the medium of lifters in the form of two bell-cranked
arms d, one employed in connection with the one plate, and the other in connection
with the other plate, but worked in unison, and mounted upon pins or pivots

page_text: centres d', carried by the end bracket part 63, of the burner 6. Each of these
lifter members have two branches, viz., a ball ended one d², and a plain one d³. The
ball-ended members d act and slide upon the plain underside end parts c¹, of the
griller wings c, c', whilst the plain branches are operated upon by outstanding
hook-shaped branches e³, of a pull and push slide or bar e, having a pull and push
handle e, and with slots e, in the said bar, working over and upon outstanding
guide brackets e, cast in common with the outside walls of the general framing.
Now by pushing the pull and push bar e, in the direction indicated by the full
arrow, the solids e, of the outstanding branches e, slide upon the nearside edges d*,
and by the sliding action, the lifters are turned from left to right, and the griller
plates are pressed upwards or lifted until their outside edges co, abut against the
overhanging flanges, of the burners 62, and which plates are sustained or propped
up by the impingements e', coming upon the offsides of the centres upon which
the crank arms turn.
By now pulling the handle e³, in the direction indicated by the dotted arrow,
the bar e, is slid in a reverse direction until the impingements e, of the branches es
come away from the branches d³, of the lifters d, when by their own weight the
griller plates fall, and resume their normal postions, as represented in Figure 4.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what
I claim is :-
First. In gas grillers or griller stoves, mounting and jointing the griller plates
wing-wise or double flap wise, and with the joint centres of the same coming at the
ends of their opposed edges, substantially as described and set forth.
Secondly. In gas grillers or griller stoves, mounting and jointing the griller
plates wing-wise or double flap wise, and with the joint centres of the same
coming at the ends of their opposed edges, and with the extreme pivot ends of the
said joints resting within bearings formed out of or sunken within the burner sides,
substantially as described and set forth.
Thirdly. In gas grillers or griller stoves, lifting the wings of griller plates, and
also staying or affixing them in their grilling positions by lifters or cranked arms,
worked by or released by a pull and push slide, or by a pull and push slide having
outstanding branches, impingements or snugs, substantially as described and set
forth.
Fourthly. In gas grillers or griller stoves, the combination with winged and
jointed griller plates, of jointed lifters d, d', d, d³, d', worked by a pull and push
slide, rod or bar
e, having outstanding branches e², with impingements e¹,
substantially as described and set forth.
Fifthly. In griller stoves or gas grillers, the improvements in the means for
lifting, lowering and sustaining horizontally the griller plates, substantially as
described and set forth.
Sixthly. In gas grillers or griller stoves, the general construction, arrangement
and combination of the parts substantially as described and set forth.
