PROVISIONAL SPECIFICATION.
Improvements in Oil and Petroleum Lamps.
I, EDOUARD CHARLES ACHILLE ROBILLARD, of 21 Rue Mogador Havre
France Watchmaker do hereby declare the nature of this invention to be as
follows:-
This invention relates to an oil or petroleum lamp, and has for its object to
provide a lamp suitable for use with petroleum which will regulate the supply of
the liquid to the burner, and have perfect safety in using, being at the same time
of simple and cheap construction.
According to my invention, the reservoir for containing the liquid is separated
from the compartment into which the wick projects, by two partitions, forming an
intermediary chamber. The reservoir communicates with this central chamber by
a small tube, which can be closed at each end by the devices hereinafter described.
The burner is of any suitable construction, according to the various uses to which
the lamp is applied, a circular burner with central air passage being preferred..
The partition dividing the wick-compartment from the central chamber, is pierced
in one or more places, allowing the liquid to penetrate to the wick. Inside the
central chamber is placed a float of metal or other material, on the end of a pivotted
lever, the other end of which is provided with a small pad, which, when the float is
raised, presses on the end of the communicating tube, closing it completely. Inside
the reservoir a regulator is placed, consisting of a plate, having a pad, which is
capable of partially or completely closing the inner end of the communicating tube.
A rod, screwed at its end, and provided with a nut, serves to adjust the position of
the regulator, allowing the petroleum to escape to the chamber at any desired
speed. When the liquid in this central chamber reaches a certain level, the float
is raised, closing the tube completely and allowing no further supply until a certain
amount has been consumed, thus always limiting the quantity within this chamber.
Should the lamp be tilted forward, the liquid accumulating at one end will raise the
float and close the tube, even if the limit has not been reached. An aperture with
screwed cap is provided at the top of the reservoir, through which the liquid is
supplied. This lamp can be applied in several ways: As a reading or desk lamp,
the body being fastened by means of a screw on a rod with a heavy base, the lamp:
being adjustable to any height, the rod may also be provided with a ring at top, if
required, to be hung from the ceiling or other part of the room. It may also be
used as an ordinary hand lamp, and can be provided with two or more burners :
arranged at suitable points around the body and constructed as above described.

COMPLETE SPECIFICATION.
Improvements in Oil and Petroleum Lamps.
I, EDOUARD CHARLES ACHILLE Robillard, of 21, Rue Mogador, Havre,
France, Watchmaker, do hereby declare the nature of this invention and in what
manner the same is to be performed, to be particularly described and ascertained.
in and by the following statement:-
This invention relates to an oil or petroleum lamp, and has for its object to

page_text: provide a lamp suitable for use with petroleum, which will regulate. the supply of
the liquid to the burner, and have perfect safety in using, being at the same time
of simple and cheap construction.
According to my invention, the reservoir for containing the liquid is separated
from the compartment into which the wick projects, by two partitions, forming an
intermediary chamber. The reservoir communicates with this central chamber by
a small tube, which can be closed at each end by the devices hereinafter described.
The burner is of any suitable construction, according to the various uses to which
the lamp is applied, a circular burner with central air passage being preferred.
The partition dividing the wick-compartment from the central chamber, is pierced
in one or more places, allowing the liquid to penetrate to the wick. Inside the
central chamber is placed a float of metal or other material, on the end of a pivotted
lever, the other end of which is provided with a small pad, which, when the float is
raised, presses on the end of the communicating tube, closing it completely.
Inside the reservoir a regulator is placed, consisting of a plate, having a pad, which
is capable of partially or completely closing the inner end of the communicating
tube. A rod, screwed at its end, and provided with a nut, serves to adjust the
position of the regulator, allowing the petroleum to escape to the chamber at any
desired speed. When the liquid in this central chamber reaches a certain level, the
float is raised, closing the tube completely and allowing no further supply until a
certain amount has been consumed, thus always limiting the quantity within this
chamber. Should the lamp be tilted forward, the liquid accumulating at one end
will raise the float and close the tube, even if the limit has not been reached.
aperture with screwed cap is provided at the top of the reservoir, through which
the liquid is supplied. This lamp can be applied in several ways:-As a reading,
or desk lamp, the body being fastened by means of a screw on a rod with a heavy
base, the lamp being adjustable to any height, the rod may also be provided with a
ring at the top, if required, to be hung from the ceiling or other part of the room.
It may also be used as an ordinary hand lamp, and can be provided with two or
burners arranged at suitable points around the body and constructed as above
described.
An
In order that the invention may be more clearly understood, reference is had
to the accompanying sheet of drawings in which
Fig. 1 is a vertical section, and Fig. 2 a sectional plan of the improved lamp and
regulator.
The invention is shown as applied to a particular form of lamp, but any other
form is suitable in which the burner is not situated directly above the reservoir.
A is the reservoir or body of the lamp carried by the stand B with a heavy-base b,
the tube a encircling the upright rod.
A thumbscrew a is employed to fix the lamp at the required height.
At the lower part of the reservoir is situated the extension C, projecting to one
side, at the outer end of which the burner is fitted. The extension is furnished
with a dividing plate D, separating it into two compartments, in the outer one of
which the wick from the burner dips. The two compartments communicate by
holes or perforations d in the plate D. The oil passes from the reservoir to the
extension C through the bent tube E, which projects through the side of the
reservoir. This tube can be completely or partially closed at its inner end by
the regulator F, which is adjusted by the screwed rod f, projecting through the top
of the reservoir, and nut. All communication with the burner can thus be cut off
whenever desired, so that when the lamp is not in use, the reservoir can be
completely closed.
At the outer end of the tube is pivotted the lever G having a pad g at one end
in such a position that it can close the tube, and the float g at the other. This
acts as an automatic regulator, only allowing a certain amount of liquid to
accumulate in the extension, the float being raised when the liquid attains a
sufficient height.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
;-
(1) A lamp of the kind described, having a reservoir, with an extension or
chamber at its lower part carrying the burner, a small tube from the reservoir
communicating with the chamber, and an automatic regulator in the chamber,.
consisting of a lever or stop with a float closing the end of the tube when the liquid
in the chamber has reached the required height, substantially as described.
(2) In a lamp of the kind described, the combination of a reservoir and chamber
with burner at its lower part, communicating with each other by means of a tube,.
with two regulators, one in the reservoir, operated by hand and wholly or partially
closing the inner end of the tube, and the other in the chamber consisting of a float.
and lever or stop closing the other end of the tube when the required amount of
liquid has accumulated substantially as described.
(3) The improved safety device for lamps, consisting of a reservoir with separate
divided chamber carrying the burner, a communicating tube, and two regulators,
one in the reservoir, and the other in the chamber, constructed and operating
substantially as described' and shown in the accompanying drawings.
