Sections 18 to 21 of the Paients. Designs, and Trade Marks Act, 1883.
I JOHN CLAYTON MEWBURN of 169 Fleet Street, in the City of London, Fellow
of the Institute of Patent Agents do hereby declare the nature of my invention
for "IMPROVEMENTS IN PETROLEUM OR OIL STOVES to be as follows:-
The stoves hitherto constructed for burning petroleum or other oils have several
disadvantages amongst which are the following
1. A bad smell from a smoky flame which gives out scarcely any heat in conse-
quence of imperfect combustion.
2. It is impossible to keep up a uniform heat so as to prevent the burning of the
food that is being cooked and to shield the combustion from errrents of air so as
to maintain the steadiness of the flame.
By the present improvements these disadvantages are avoided and a complete
combustion of perfect regularity is obtained; a supply of cold air sufficient to cool
the wick or burner of the lamp is provided for whilst at the same time a consider-
able economy in oil is realized.
In the centre of the lamp portion of the improved stove which may be of any
suitable form, is a vertical tube of thin copper formed at its upper end with a part
of larger diameter which shields the flame from the interior current of air. This
arrangement completely avoids the intermittent, partial and momentary extinctions
The flame is
of the flame caused by the coldness of the internal current of air.
thus constantly regular. The part of larger diameter which shields the flame may
either be formed out of the metal of the vertical tube or be a small angle piece.
A ring attached by radial pieces to the central tube is intended to regulate the
currents of air by diminishing the natural section of the central tube. The same
result can be obtained by introducing into the central tube either upon its inner
sides or upon the rod of the flame spreader cylindrical or other shaped obstructions.
The stem or rod of the spreader enters a copper tube fixed by arms in the centre of
the central tube. The spreader is movable and allows of easily trimming and
cleaning the wick and the upper part of the lamp burner; further the insulation
caused by the copper tube partly prevents the heating of the lamp body.

page_text: The central tube is surrounded at its lower part by a second tube pierced with
holes the edges of which are left rough so as to better retain a covering of felt or
wool upon which the wick is adjusted. The second or wick tube is provided at
its lower part with a projection which connects it to a rack placed in a rectangular
tube one side of which is removed for a certain distance to allow of the passage of
the projection in the up and down movement of the rack.
A button which actuates a pinion gearing with the rack is provided with a rod
sufficiently long to be worked from the outside of the body of the stove. To
prevent the weight of the wick carrier causing the rack and its guide to descend
after a certain amount of wear, I fix in the guide a small spring plate which will
maintain a constant regular pressure. This special arrangement of mounting the
rack by properly guiding the wick tube prevents the wedging of the latter against
the central tube. I can obtain the same result by the employment of suitable
levers. The felt covering before mentioned is specially designed to be easily
placed upon the wick carrier. It consists of a piece of felt on which are
sewn a sufficient number of bands which are to be tied around the wick
carrier. The placing of the felt is thus simplified; it is only necessary to cut
off the loose ends of the bands. The gallery is fixed to the lamp by means of
hooks which when the gallery is turned take into rings on the lamp. The
lower part of the stove is formed with small holes to diminish the action of the
currents of air and thus avoid the production of smoke black under the cooking
utensils. The chimney is conical and its larger diameter is fixed at bottom to a
plate or basin which connects it to the stove body. This plate has an opening
opposite the chimney to give passage to the flame. It is provided with one or two
washers superposed and connected by rivets but between which there is a certain
space to give passage to the external air. For the sake of economy the central
portion or bottom of this plate or basin is formed of a washer of copper; the
employment of this metal is necessary to prevent the heat radiating over the body
of the lamp. The currents of air which enter between the superposed washers
forcibly drive the whole of the air currents towards the upper part of the wick.
The other current of air coming beneath these washers serves to cool the wick; the
ascensional current may thus be driven forcibly towards the flame by the action of
the small currents from the washers and insures a good combustion and the sup-
pression of all smell. The bottom of the plate or basin is formed with holes for
the purpose of allowing of the flow of liquid matters which may be permitted to
fall into the body of the stove and also of establishing a current of cold air along
the chimney. The chimney is fitted with a spy tube at the side of conical form.
The grating which is fixed at the upper part of the stove has a hinged plate or heat
spreader which can be lowered to a position above the top of the chimney; it thus
prevents the direct action of the flame upon the objects placed on the stove.
stove is provided with a movable plate warmer formed of two perforated plates
superposed one above another at a short distance apart. It is placed on the stove
when the hinged plate is closed. As this warmer receives the heat already
tempered by the hinged plate or heat spreader and constitutes by the superposition
of its two plates a sort of air box it keeps the plates hot without fear of overheating
them. The plate or basin which supports the chimney as already described is made
concave in order to give more space for lighting the lamp. The lamp constructed
as hereinbefore described can be placed in a sheet iron casing so as to form an air
heating stove for warming apartments.

of the Institute of Patent Agents do hereby declare the nature of this invention
(a communication from abroad by Jacques Aimé Vagner of N° 1 Boulevard
St Denis, Paris, France, Manufacturer) and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement:-
The stoves hitherto constructed for burning petroleum or other oils have severai
disadvantages amongst which are the following a
1. A bad smell from a smoky flame which gives out scarcely any heat in conse-
quence of imperfect combustion.
2. It is impossible to keep up a uniform heat so as to prevent the burning of the
food that is being cooked and to shield the combustion from currents of air so as to
maintain the steadiness of the flame.
By the present improvements these disadvantages are avoided and a complete
combustion of perfect regularity is obtained; a supply of cold air sufficient to cool
the wick or burner of the lamp is provided for whilst at the same time a consider-
able economy in oil is realized.
The annexed drawings illustrate the invention. Figure 1 is a vertical section
representing the arrangement or combination of the various parts of which the
stove is composed. Figure 2 is a plan of the lamp tubes. Figure 3 is a plan of the
stove. Figure 4 represents a-novel-form of felt-covering which-can-be-easily fixed
on the wick-tube. Figure 4 represents in vertical section a stove differing some-
what from that shown in Figure 1. Figure 6 is a plan of the flame sprender used
with the lamp shown in Figure 5. Figure 5 represents a modified form of the
washer used for keeping the wick cool.
In the centre of the lamp portion of the improved stove which may be of any
suitable form is a vertical tube of thin copper or brass formed at its upper end
with a part c of larger diameter which shields the flame from the interior current
of air. This arrangement completely avoids the intermittent partial and momentary
extinctions of the Hame caused by the coldness of the internal current of air. The
flame is thus constantly regular. The part c of larger diameter which shields the
flame may either be formed out of the metal of the vertical tube or be a small
angle piece.
A ring & attached to the tube b is intended to regulate the currents of air by
diminishing the natural section of the tube b. The same result can be obtained by
introducing into the tube either upon its inner sides or upon the rod of the flame
spreader cylindrical or other shaped obstructions. The stem or red of the
spreader f-enters a copper or brass-tube-h-fixed-by-arms-g, gr-g-in the centre of the
tube 6. The spreader is movable and allows of the wick and the upper part of
the lamp burner being easily trimmed and cleaned; further the insulation caused
by the tube-h-partly prevents the heating of the lamp body.
The tube--is surrounded at its lower part by a second tube k-pierced with holes
the edges of which are left rough so as to better retuin a covering 1-of-felt or woollen
upon which the wick y is adjusted. This second or wiek tube-k is provided at its

page_text: tower part with a projection' which connects it-to-n-rack-j-plneed-in-a-rectangular

maintain a constant-regular-pressure. The projection j₁ being fixed to the lower
part of the-tube-k-wieks whose length is equal to the height of the lamp can be
employed. This special arrangement of mounting the rack by properly-guiding the
wick-tube-k-prevents the wedging or jamming of the latter against the tube b
The same result can be obtained by the employment of suitable levers. The
felt covering 1-(see Figure 4) is specially designed to be easily placed upon the
wick carrier-k. It consists of a piece 7 of felt (or woollen) on which are sewn-
sufficient number of bands 1,1--which are to be tied around the wick carrier.
The placing of the felt is thus simplified; it is only necessary to cut off the loose
ends of the bands after they have been tied. The wick-y-is afterwards-placed-over
the-felt and for greater security it can be rigidly fixed by an elastic ring of metal or
enoutehone. The gallery m is fixed to the lamp by means of hooks m', m¹ which
when the gallery is turned take into rings on the lamp. The lower part of the stove
is formed with small holes to diminish the nation of the currents of air and thus avoid
the production of smoke black under the cooking utensils. The chimney t is
conical and its larger diameter is fixed at bottom to a plate or basin q which
connects it to the stove body. This plate q has an opening opposite the chimney
to give passage to the flame. It is provided with two superposed washers 7', q¹
connected by rivets and having between them a certain space to give passage to
the external air. For the sake of economy the central portion or bottom of this
plate or basin q is formed of a washer q₁ of copper; the employment of this metal is
important to prevent the heat radiating over the body of the lamp. The currents of
air which enter between the superposed washers 7', 7' forcibly drive the whole
of the air currents towards the upper part of the wick y..
The other current
of air coming beneath these washers serves to cool the wick; the ascensional
current may thus be driven forcibly towards the flame by the action of the small
currents from the washers and insures a good combustion and the prevention of all
smell. The bottom of the plate or basin q is formed with holes a, a for the purpose
of allowing of the flow of liquid matters which may be permitted to fall into the
body of the stove and also of establishing a current of cold air along the chimney t
The chimney is fitted with n-spy tube-s-at-the-side of conical form. The grating z
which is fixed at the upper part of the stove has a hinged plate or heat spreader p
which can be lowered to a position above the top of the chimney; it thus prevents
the direct action of the flame upon the objects placed on the stove. The stove is
provided with a door at the side and with handles by which it can be lifted.

The
In the stove represented in Figure 4 the cooling of the wick, which in the stove
shown in Figure 1 is provided for by the use of two superposed washers q, q
connected by rivets, is obtained by means of a single washer a which is very thick
so that its sides may form a passage, or it may be thin and have a flange b giving
it the form of a bottomless dish. The flume-spreader is formed with holes in the
centre (see Figure 6) to allow of the air being supplied at the middle of the flume
and give this a vertical form. The cold air passing through these holes-enters the
washer a und prevents it getting overheated-and-therefore-causing a distribution
of too much hent to the wick: The casing is pierced with holes which allow of
the inlet of sufficient air to cool the chimney. The air entering through these holes
cools the upper part of the chimney and therefore prevents overheating of the top
of the flame while maintaining the draft necessary for a suitable proportion of
internal and external currents.

Figure 5 shows another form of wick cooler in which this device is made in a
piece with the plate or basin that carries the chimney but is formed with small
holes s which establish air currents.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, as communicated to
me, I declare that what I claim, in respect of petroleum or oil stoves, is :-
1. The lamp a fitted with a central tube and flame spreader f, in combination
with a wick cooler q¹, substantially as hereinbefore described and represented
in Figures 1, 2 and 3.

In the stove represented in Figure 5 the cooling of the wick, which in the stove

so that its sides may form a passage, or it may be thin and have a flange b giving

and give this a vertical form. The cold air passing through these holes enters the
washer a and prevents it getting overheated and therefore causing a distribution
of too much heat to the wick. The casing i is pierced with holes j which allow of
the inlet of sufficient air to cool the chimney. The air entering through these holes
cools the upper part of the chimney and therefore prevents overheating of the top
of the flame while maintaining the draft necessary for a suitable proportion of
internal and external currents.
