We JOHN FREDERIC WRIGHT and GEORGE ERNEST WRIGHT both of the Firm of
John Wright & Co. of Essex Works Thimble Mill Lane Aston in the County of
Warwick Gas Engineers, do hereby declare the nature of our said invention to be as
follows:-
Our invention has for its object improvements in gas burners for cooking apparatus
or ranges which enables us to distribute the gas flame better as well as to manipulate
the same for various purposes in cooking such for instance as in using the same
burner or burners or apparatus for both boiling and grilling and toasting and we are
able to clean such burners more effectively and this we accomplish without the expenч
of drilling.
The pipe or tube or pipes through which we pass our gas and air by any usual
fittings at the outer open end we make from cast metal all in one casting and either
straight or with any desired bend or bends to suit the position and purpose and we
form thereon longitudinally a continuous projecting nose piece with serrated sides and
in this we cast a longitudinal slot which joins on to the main round core or is a part
thereof when casting and so the slot and centre main passage are one clear complete
whole formed from end to end ready to receive the burner of usual end brass or other
fittings. For the purpose of properly distributing the gas as it issues from the said
slot we cast a tongue piece tapered lengthwise and having generally a rounded thin
under edge and we make latteral recesses or grooves all along this tongue on both
sides thereof so that when it is placed in the before mentioned longitudinal recess a
number of oblong passages are formed along the sides and thus as the mixture of gas
and air travels along the tube it issues and is consumed in a number of outlets so
formed which produces a very perfect and pure flame.

page_text: In fitting these burners in cooking apparatus say where two cross tubes constitute
the burner we connect the two by two cranks under the front end into which a key or
spanner enters and by lifting or turning the said handle or key each of the tubes are
turned upon bearings which run in a back frame and on front pivots or bearings
so as to direct the flame upwards when required for boiling purposes but otherwise the
flames would issue under à deflector plate when used for grilling or toasting.

By this means we very quickly convert our grilling apparatus into jets for boiling
pans etc. which is a great saving of room and convenience in such apparatus.

Improvements in Gas Burners for Cooking Apparatus.
We JOHN FREDERIC WRIGHT and GEORGE ERNEST WRIGHT both of the firm of
John Wright & Co. of Essex Works Thimble Mill Lane Aston in the County of
Warwick, Gas Engineers, do hereby declare the nature of our said invention and in
what manner the same is to be performed to be particularly described and ascertained
in and by the following statement :-
Our invention has for its object improvements in gas burners for cooking apparatus
or ranges which enables us to distribute the gas flame better as well as to manipulate
the same for various purposes in cooking such for instance as in using the same
burner or burners or apparatus for both boiling and grilling and toasting and we are
able to clean such burners more effectively and this we accomplish without the
expense of drilling.
The pipe or tube or pipes through which we pass our gas and air by any usual
fittings at the outer open end we make from cast metal all in one casting and either
straight with any desired bend or bends to suit the position and purpose and we form
thereon longitudinally a continuous projecting nose piece with serrated sides and in
this we cast a longitudinal slot which joins on to the main round core or is a part
thereof when casting and so the slot and centre main passage are one clear complete
whole formed from end to end ready to receive the burner of usual end brass or other
fittings.
For the purpose of properly distributing the gas as it issues from the said slot we
cast a tongue piece tapered lengthwise and having generally a rounded thin under
edge and we make lateral recesses or grooves all along this tongue on both sides
thereof so that when it is placed in the before mentioned longitudinal recess a number
of oblong passages are formed along the sides and thus as the mixture of gas and air
travels along the tube it issues and is consumed in a number of outlets so formed
which produces a very perfect and pure flame.
In fitting these burners in cooking apparatus say where two cross tubes constitute
the burner we connect the two by two cranks under the front end into which a key or
spanner enters and by lifting or turning the said handle or key each of the tubes are
turned upon bearings which run in a back frame and on front pivots or bearings so as
to direct the flame upwards when required for boiling purposes but otherwise the
flames would issue under a deflector plate when used for grilling or toasting. By this
means we very quickly convert our grilling burners into jets for boiling pans &c.
which is a great saving of room and convenience in such apparatus.
In order that our invention may be properly understood we have appended
hereunto a sheet of drawings containing ten Figures which illustrates its application to
one of our cookers.
Figure 1 is a perspective view of the Cooker with the burner apparatus applied
thereto.

page_text: Figure 2 is a broken off end view showing the levers at the outside of the end for
operating the burners.
Figure 3 is a broken off cross sectional elevation looking towards the levers.
Figure 4 is a broken off front elevation showing the gas inlet.
Figure 5 is a plan of one of the burners on a larger scale.
Figure 6 is a longitudinal part section and part elevation of the burner.
Figure 7 is a broken off full sized plan of a portion of the burner.
Figure 8 is a full sized sectional elevation of the portion of the burner shown by
Figure 7.
Figure 9 is a cross section of one of the burners on the line A B.
Figure 10 is a cross section of one of the burners on the line C. D.
We construct our burners E and E with a long slot or slit e² into which the
serrated tongue piece K fits by which means we are enabled to make the recesses k¹
through which the gas and air issues by casting instead of drilling and the tongue K
may be removed and the burner cleaned in a very simple and easy manner which is a
considerable advantage. The tongue K is made deeper at the end where the gas
and air enters and the grooves are less defined and square at the edges than
they are at the further end which equalizes the quantity of gas issuing at the two
ends which is more clearly shown by the cross section Figure 9 of the entrance
end and cross section Figure 10 of the further end of the burner where the square
broad bottom of tongue K in Figure 9 contracts with its narrow rounded edges in
Figure 10. The outside part E of the burner is easily male from cast iron and the
slot eis cored out as a part of the main core so that when the two castings E and K
are properly-dressed or cleaned the two come together and constitute the burner.
We hang these burners E and E in the end bracket at the outer end and in a
special bracket N at the other end and the crank pin 3 of the crank e works in the
quadrant slots m³ m², that is there is a quadrant slot for the crank pin of each burner.
These burners may be turned just about 90° by means of the two levers P and Q which
are carried by the cap R and each lever embraces its particular crank pin by means
of a slot q' or p¹. It is therefore only necessary to draw or push either lever to turn
the burner to the angle required for either a vertical flame or a horizontal flame. It
will also be evident that with the two one burner may be vertical and the other
horizontal though the intention is to work them in pairs. There may also be any
number of such burners.
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 :-
The improvements in gas burners for cooking apparatus or ranges of a burner
onstructed of the two parts E and K and operated by cranks and handles so as te
act either vertically or horizontally substantially as and for the purpose herein
set forth.
