BURNERS FOR MINERAL AND OTHER OIL, VAPOUR, AND GAS" A communication
from Messieurs Mousot et Folliot, persons resident at No 14, Quai d'Orsay, Paris,
in the Republic of France
The Invention communicated to me consists in a new burner, applicable to all
lighting apparatus burning mineral or vegetable oils, spirit, or gas
The improved burner is constructed of a double tube containing a wick moved by
the ordinary means At the bottom is a projection or rim receiving a perforated
metal or porcelain basket This basket is covered in at the top, the cover being
pierced with two circles of holes The inner circle or series of holes sends the air
between the tube and a plain metal cone The second or outer cucle of holes sends
the air between the herein-before described cone and an outer perforated cone of
porcelain or other suitable material Around is placed the gallery for receiving the
glass.

"IMPROVEMENTS IN

page_text: BURNERS FOR MINERAL AND OTHER OIL, VAPOUR, AND GAS" A communication
from Messieurs Morisot ct Folliot, persons resident at No 14, Quai d'Orsay, Paris,
in the Republic of France
The Invention communicated to me consists in a new burner, applicable to all
lighting apparatus burning mineral or vegetable oils, spirit, or gas.
The improved burner is constructed of a double tube containing a wick moved
by the ordinary means At the bottom is a projection or in receiving a perforated
metal or porcelain basket. This basket is covered in at the top, the cover being
pierced with two circles of holes The inner circle or series of holes sends the air
between the tube and a plain metal cone The second or outer cicle of holes sends
the au between the herein-before described cone and an outer perforated cone of
porcelain or other suitable material Around is placed the gallery for 10ceiving the
glass, which may be of any suitable form, but I prefer the ordinary straight or
elbowed glasses
But to make the Invention communicated to me better understood I will proceed
to describe the saine by reference to the accompanying Drawing, in which Figure 1
represents a section, and Figure 2 a plan of a burner constructed according to this
Invention
A is the wick (which may be flat or round), moved by means of the rod C, pro-
vided with a pinion or by other suitable known means The air anters the interior
by a suitable opening B The burner is provided with a screw thread at N for
connecting it with the lamp on other apparatus containing the liquid to be burned,
o it may be connected in any other suitable manner The projection or rim L
carries the bell-shaped baskot J, perforated with small holes This basket may be
made of metal, porcelain, glass, earthenware, or other suitable material, and receives
at its upper pait the glass calier E, which forms a horizontal closing or cover
through which passes the wick tube The cover is perforated with two circles of
holes, the inner circle of holes G being small and serving to introduce the an near
the tube A, B, the holes II in the outer cucle are larger and cause the an to pass
further from the tube between two tiuncated cones, one of which F 18 of metal, and
the other D is of porcelain, metal, or other suitable, material, and is perforated with
small holes
With this improved apparatus or buiner the an anives around the wick at a
suitable speed and in the proper direction, and serves to produce a more steady and
white light than that obtained by the buiners hitherto in use
The use of this improved burner also avoids the 11sk of explosion, and allows of
burning in all kinds of lamps any of the combustible liquids hitherto employed
In witness whereof, I, the sud Hector Auguste Dufrené, have hereto set
my hand and seal, this Twenty-first day of July, in the year of our Lord
One thousand eight hundred and seventy-seven
