IMPROVEMENTS IN LAMP STOVES
Year: 1885

page_text: I EDWARD ALEXANDER RIPPINGILLE of The Aston Brook Lamp Works, Aston-
juxta-Birmingham in the County of Warwick, Lamp Manufacturer do hereby
declare the nature of the said Invention for IMPROVEMENTS IN LAMP STOVES to
be as follows:-
The invention relates Firstly to means whereby I am enabled to construct a
taller oven than heretofore at a moderate price and at the same time am enabled
to bring the heat from the burner or burners sufficiently near to the top of the
stove to ensure sufficient heat being conveyed to utensils placed above the oven
whilst at the same time I provide means for properly heating the sides, back and
bottom of the oven.
For this purpose in lieu of placing the burner or burners below the level of the
bottom of the oven I place it or them some distance up the sides thereof, the
chimney or chimnies for such burner or burners is or are enclosed in a chamber or
space formed at one or both sides of the oven which chambers or spaces com-
municate freely with the interior of the oven so as to enable the heat from the
chimney or chimneys to be freely radiated into the same.
I also provide the oven with flues at the top, back and bottom thereof and
I divide the aforesaid side chimney or chimneys vertically and arrange the various
parts in such manner that part of the products of combustion from the side burner
or burners is caused to pass up to heat utensils placed on the top of the stove and
part is caused to pass from the side chimney or chimneys into the flue over the top
of the oven, and thence through the back flue to the bottom flue whence it is
drawn into the second part of the divided side chimney or chimneys and away at
the upper part of the chimney or chimneys. If desired a slide or slides may be
used to shut off the heated products of the side burner or burners from the oven
flues when the oven is not required for use.
As a modification of the above I dispense with the divisions in the side chimney
or chimneys and cause all the products of combustion to rise through the side
chimney or chimneys and to pass away directly from the top of the stove after
having heated the utensils placed thereon and I employ a burner or burners under-
neath the oven and cause the products of combustion therefrom to traverse the
bottom flue and thence to pass up the back flue into the space at the top of the.
oven and finally to pass away in the usual manner.

stoves to means for preventing the heat of the flames from passing down to and
thereby unduly heating the wick tubes and wicks.
For this purpose instead of constructing the cone of the burner with two slots
both sides of each of which are at the same level I construct such cone with the
central dividing bar between the two slots depressed below the level of the metal
forming the outer sides of said slots whereby I somewhat deflect the flames inwards
towards each other and I place a barrier to prevent the heat of such flames from
passing or being reflected downwards between the wick tubes.

I EDWARD ALEXANDER RIPPINGILLE of "The Aston Brook Lamp Works"
Aston-juxta-Birmingham in the County of Warwick Lamp Manufacturer do
hereby declare the nature of this invention and in what manner the same is to
he performed to be particularly described and ascertained in and by the following
statement:-
The invention relates Firstly to means whereby I am enabled to construct a
taller oven than heretofore at a moderate price and at the same time am enabled
to bring the heat from the burner or burners sufficiently near to the top of the
stove to ensure sufficient heat being conveyed to utensils placed above the oven
whilst at the same time I provide means for properly heating the sides, back and
bottom of the oven.
For this purpose in lieu of placing the burner or burners on a level with or
below the level of the bottom of the oven as heretofore in stoves arranged for both
baking and boiling with the same burner or burners, I place it or them some
distance up the sides thereof, the chimney or chimneys for such burner or burners
is or are enclosed in a chamber or space formed at one or both sides of the oven
which chambers or spaces communicate freely with the interior of the oven so
as to enable the heat from the chimney or chimneys to be freely radiated into
the same.
I also provide the oven with flues at the top, back and bottom thereof and
I divide the aforesaid side chimney or chimneys vertically and arrange the various
parts in such manner that part of the products of combustion from the side burner
or burners is caused to pass up to heat utensils placed on the top of the stove and
part is caused to pass from the side chimney or chimneys into the flue over the top
of the oven, and thence through the back flue to the bottom flue whence it is
drawn into the second part of the divided side chimney or chimneys and away at
the upper part of the chimney or chimneys.
If desired a slide or slides may be used to shut off the heated products of the
side burner or burners from the oven flues when the oven is not required for use.
As a modification of the above I dispense with the divisions in the side chimney
or chimneys and cause all the products of combustion from the side burners to rise
through the side chimney or chimneys and to pass away directly from the top of
the stove after having heated the utensils placed thereon and I employ a burner or
burners underneath the oven and cause the products of combustion therefrom to
traverse the bottom flue and thence to pass up the back flue into the space at the
top of the oven and finally to pass away in the usual manner.
The invention relates secondly when employing double wick burners for lamp
stoves to means for preventing the heat of the flames from passing down to and
thereby unduly heating the wick tubes and wicks. For this purpose instead of
constructing the cone of the burner with two slots both sides of each of which are
at the same level, I construct such cone with the central dividing bar between the
two slots depressed below the level of the metal forming the outer sides of said
slots whereby I somewhat deflect the flames inwards towards each other and
I place a barrier to prevent the heat of such flames from passing or being reflected
downwards between the wick tubes.

horizontal section drawn on the line 5, 5, of Figure 4 representing a lamp stove
constructed according to a modification of my invention; and Figures 8 and 9
and 10 and 11 represent respectively cross sections and longitudinal sections and
Figure 12 is a cross section and Figure 13 is a plan of double wick burners
constructed according to my invention.
In all the figures like parts are marked with similar letters of reference.
I will first describe the arrangement of lamp stove represented at Figures 1, 2, 3,
-a represents the oven, and bb the burners for heating the same, and b¹ b' the
tanks for supplying the said burners.
In carrying my invention into effect, in lieu of placing the burners as heretofore
on a level with or below the level of the bottom of the oven, I place them some
distance up the sides thereof, as shown and I enclose each of the chimneys c for
such burners b in a chamber or space d formed at each side of the oven a which
chambers or spaces communicate freely with the interior of the oven a so as to
.enable the heat from the chimneys to be freely radiated into the same.
I also
provide the oven a with flues e, f, g, respectively at the top back and bottom
thereof and I divide the aforesaid side chimneys c vertically and arrange the
various parts in the manner shown in the drawings so that part of the products of
combustion from the side burners, is caused to pass up the flues or chimneys c to
heat utensils placed on the top of the stove and part is caused to pass from the
side chimneys c into the flue e over the top of the oven, and thence through the
back flue to the bottom flue g whence it is drawn into the second part c¹ of
the divided flues or chimneys c and away at the upper part of such chimneys c¹.
In order to ensure the heat and products of combustion traversing the entire area
of the bottom flue g, I place deflectors g¹ in such bottom flue and I limit the length
of the opening f¹ from the back flue f to the length of the space between such.
deflectors g and in order to obtain a draft through the chimney c¹ and thereby
ensure a proper circulation of such heat and products of combustion as above
described, carry the bottoms of the chimneys c¹ down to and connect them with
the flue g and I carry the tops thereof to a higher level than the tops of the.
chimneys c. Although in the drawings I have shown the burners bb to be only
single wick burners they will in some cases be double wick burners. If desired a
slide may be used to shut off the heated products of combustion of the side
burners c from the oven flues e, f, g, when the oven a is not required for use.
I also in order to ensure a circulation of the air within the body of the oven,
partially enclose the chambers or spaces d with a plate d¹ in which I form
openings d² d³ at the upper and lower parts of the same.
I will now describe the modification represented at Figures 4, 5, 6 and 7. In
this case I arrange the side burners b b in a similar manner in relation to the oven a
to that described with respect to the arrangement shown at Figures 1, 2, 3, but
I dispense with the second portions c¹ of the side chimneys and cause the products
of combustion from the side burners to rise through the side chimneys c and to pass
away, directly from the top of the stove after having heated the utensils placed
thereon and I employ a burner or burners i underneath the oven and cause the
products of combustion therefrom to traverse the bottom flue g and thence to pass

page_text: up the back flue f into the space between the top of the oven and the top plate and
finally to pass away in the usual manner.
The bottom burner or burners & may be placed in the direction shown, or at
right angles thereto.
I also in order to secure circulation of the air within the oven a enclose tho
chambers or spaces d with a plate dat both back and front of the oven and forin
openings & therein, and I extend the back portion of the chambers d down to
the bottom of the oven a and make the back openings ds therein below the
perforated false bottom a¹ thereby ensuring a circulation of the heated air within
the body of the oven and underneath the false bottom a¹.
If desired slides ¹ may be employed to prevent the circulation of the heated air
between the oven and the side spaces or chambers & when the oven is not required
for use.
In order to prevent the heat of the oven from being communicated to the oil
tanks b¹ I interpose plates a² between the tanks 61 and the sides of the oven so as
to leave air spaces between the sides of the oven and such plates a². I will now
describe the second part of my invention which is represented at Figures 8 to 13.
This part of my invention relates to double wick burners and consists of a novel
construction of parts whereby the heat of the flames is prevented from passing
down to and thereby unduly heating the wick tubes and wicks.
For this purpose instead of constructing the cone of the burner with two slots,
both sides of each of which are at the same level I construct the cone ; with the
central dividing bar je between the two slots j¹ depressed below the level of the
metal forming the outer sides of said slots. These bars may be formed of plain
unperforated metal as shown at Figures 8 and 9 or they may be made of perforated
metal as shown at Figures 10 and 11 or they may be formed of unperforated metal
in the centre of which is a longitudinal slot ja for the passage of air between the
flames. These bars may be formed to the section shown or to other desired
section to obtain the required strength. By these means I am enabled somewhat
to deflect the flames inwards towards each other and I place a barrier to prevent
the heat of such flames from passing or being reflected downwards between the
wick tubes.
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
1. In lamp stoves, placing the burner or burners some distance up the sides of
the oven and arranging flues and passages in such manner that the products of
combustion passing therethrough shall be capable of effectually heating utensils
placed on the top of the stove and of heating the top, back, bottom and sides of the
oven substantially as herein shown and described with respect to Figures 1, 2 and 3.
2. In lamp stoves the combination of a burner. or burners placed some distance
up the side or sides of the oven, a burner or burners underneath the oven and
suitable flues or passages for the products of combustion substantially as herein
shown and described with respect to Figures 4 to 7 and for the purpose stated, and
3. Constructing double wick burners with a depressed central dividing bar
between the slots substantially as herein shown and described with respect to
Figures 8 to 13 and for the purpose stated.
