at the Office of the Commissioners of Patents, with his Petition,
on the 19th March 1869.-A communication from abroad by Fabius
Boital, of Paris, France.
I, CLINTON EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman,
and Company, of 166, Fleet Street, in the City of London, Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN APPARATUS FOR THE USE OF PETROLEUM AND OTHER OILS AND ESSENCES
FOR THE PURPOSE OF HEATING," to be as follows:-
This Invention has for its object the employment for heating purposes
of apparatus for lighting fed by mineral or vegetable oils and essences,
whether lamps with a constant level or lamps with capillary wicks, and
especially the lamps and apparatus for the burning of petroleum, which
develops the greatest heat.
I vary the form and arrangement of my heating apparatus according
to the object to which they are to be applied and the kind of lamp
employed, and am thus able to give them very varied applications,
furnishing excellent results for the heating of water in boilers or water
baths for distillers and manufacturors of lemonade or cordials, the

page_text: distribution of heat in apartments, the heating of irons for gofferers,
solderers, hair dressers, morocco dressers, ironers, and others, the melting
of very fusible metals, the melting of glue in carpenters' workshops, the
heating of drying rooms and stoves, and generally the heating and
cooking of every kind of material and food.
The Drawings annexed to this description show in detail a specimen
of the apparatus forming the subjects of this Invention and several
examples of its principal applications.
Figure 1 is an elevation of my apparatus, and Figure 2 a sectional
elevation; Figures 3 and 4 are respectively a top plan and sectional plan
of the same apparatus. It is essentially composed of a long cylinder a
of sheet, cast, or wrought iron, porcelain, or other material, having at its
top a disc 6 pierced with holes in which the matters to be heated are
placed. In the lower part of this cylinder is the lamp c for petroleum
or other liquid which furnishes the necessary heat. The gases and
smoke produced by the combustion are carried off from the interior by
a chimney d of metal, the diameter of which is relatively small, main-
tained in the centre of the cylinder a by means of screws e, e, e. This
chimney serves besides to admit the circulation of the air indispensablo
for combustion which penetrates to the interior of the apparatus by the
holes fff, made for the purpose in the lower part of the apparatus. A
helical spring g coiled round the supporting rod h tends always to
produce an upward movement of the support, and by forcing the case of
the lamp burner to press against the base k of the chimney d ensures a
complete stability. In order to regulate the flame without opening the
door of the apparatus a thumbscrew or button is provided outside,
which may be turned by the hand, and a sight hole formed in the eylinder a,
and carried to the chimney; the latter is provided with a glass disc n
through which the intensity of the flame may be observed.
The apparatus just described may be made to serve for the heating
and preparation of food and other matters; it is only necessary to place
the vessel containing them upon the plate on the top of the apparatus,
This apparatus is the one which exemplifies the principle of this
Invention and which forms the base of the various and numerous
applications which can be made of lighting apparatus for the purpose of
heating. The amount of heat furnished by one burner not being
sufficient in the generality of cases I adapt, as will be seen by the
specimens shown in the Drawings, several burners for the same re-

page_text: servoir of oil or essence, and in these cases I vary the arrangement of
the chimneys, and enveloping cylinders according to the purpose for
which the apparatus is designed.
Figure 5 represents in elevation an apparatus of water bath arrangement
for the heating and preparation of punch, tea, or hot wine, for the use of
lemonade and cordial manufacturers; the lower parts of the vessels o, o,
containing the liquid are immersed in the water enclosed within a
receptacle A which is traversed by the chimneys p, p, p, of the lamp
burners. The glass sight holes q, q, which are likewise adapted to all
these apparatus facilitate the regulation of the flame.
Figure 6 is a view of the interior of an apparatus suitable for heating
the irons of gofferers, hair dressers, and others. The irons to be
heated r, r, are placed vertically through holes formed in a plate 8
placed across the top of the apparatus, and directly receive the heat
disengaged within the chimneys t, t, t. According to the degree of heat
desired to be communicated to the irons I place them either within the
chimneys themselves, as shown at r, or at the exterior of the chimneys
and within the case B enclosing the apparatus.
Figure 7 shows an example of a stove heated by two lamp burners
proceeding from the same reservoir. The air is fed to the apparatus by
air holes u, u, and the heat spreads into the atmosphere through
openings v, v, formed in the upper part of the apparatus. If
the inconveniences arising from the smoke and deleterious gases are
desired to be obviated they can be collected under a sort of funnel x
shown in Figure 9. This funnel leads them away through the pipe y.
Lastly, Figure 8 is the view of an apparatus forming a solderer's
blowpipe; this only differs from the others in being surmounted by a
bent tube z which is the only free passage for the flame.
The above described specimens of my apparatus will enable the
very numerous other applications of which it is capable to be readily
understood, I can for example adapt it to furnaces, boilers, dry-
ing houses, and other purposes of every kind, including the heating
of baths,
