LAMPS AND BURNERS, AND REFLECTORS THEREFOR."
This Invention consists mainly of the following arrangements.
"IMPROVEMENTS IN
My Improved lamp can be used on a bracket any distance away from the reservoir
and if necessary the reservoir need not be exposed to view. By fitting the reservoir
through a tube attached to its side as soon as the oil rises over the inlet to reservoir
the air which is then in the reservoir will get compressed and as the oil is poured
in an elastic bag, on the top of the reservoir receives the air which ascends before
the oil and returns as the oil gets consumed and by this means the oil is kept up
to the bottom of the burner until the oil descends below the level of the inlet
again.
For proper combustion air is admitted through the burner through inlets in the
lamp itself arranged so as to cause a current of air to pass around the wick between
the oil and the burner and with this current a brighter and better light is obtained
and in a given time only about 3/4 the complement of oil is consumed. The lamp I
can raise up and down at pleasure and if desired to take it off for any purpose
same can be done by means of a nut which connects it with the top of the
reservoir.
The reservoirs can be of any suitable shape or size and by making same of any
bright material would help the reflectors and increase the light.
The burner has two segmental wicks each worked up and down by two segmental
cog wheels and is provided with an extinguisher by which the light can be put out
without being moved. By pressing or squeezing together the two small handles

page_text: which work on one pivot the light from the wicks is at once extinguished. The
advantage which this burner has over other burners is when you want to reflect the
light there is a greater surface of light caught by the reflector at every side which
ever way the burner may be turned. The wicks of the burner double up and are
hung to bottom of burner so that they may twist freely around when taking off and
putting on the burner also that their ends may be exposed to the current of air.
The reflector may be round or square or any shape but its sides must slope at an
angle of 90° to each other or 45° to a plumb or level line and is constructed of best
block tin, nickel silver, polished steel or metal, and lined on the inside with fluted
glass with deep furrows.

“IMPROVEMENTS IN
This Invention consists mainly of the following arrangements.-My improved
lamp can be used on a bracket any distance away froin the reservoir, and if necessary
the reservoir need not be exposed to view. The lamp is connected with the reservoir
by means of a suitable pipe through which the oil flows as it is consumed in the
burner. In my Provisional Specification I describe the use of an air bag, which,
upon experiment, I find not economical, and I hereby disclaim the use of same. For
proper combustion air is admitted through the burner through inlets in the lamp
itself, arranged so as to cause a current of air to pass around the wick between the
oil and the burnor, and with this current a brighter and better light is obtained,
and in a given time only about 3/4 the complement of oil is consumed. The lamp I
can raise up and down at pleasure, and if desired to take it off for any purpose
same can be done by means of unscrewing it from the reservoir.
The reservoir can be of any suitable shape or size, and by making saune of any
bright material would help the reflectors and increase the light.
The burner has one segmental, and one flat wick, each worked up and down by
ordinary cog wheels. In my Provisional Specification 1 describe two segmental
wicks, but I find the arrangement of one segmental wick and one flat wick works
better. I also find the use of the extinguisher described in the Provisional
Specification adds to the complication of the Invention and I propose to dispense
with same.
The advantage which this burner has over other burners is, when you
want to reflect the light there is a greater surface of light caught by the reflector
at every side whichever way the burner may be turned.
The wicks of the burner double up and are hung to bottom of burners so that
they may twist freely around when taking off and putting on the burner also that
their ends may be exposed to the current of air.
The reflector may be round or square or any shape but its sides must slope at an
angle of 90° to each other or 45° to a plumb or level line, and is constructed of best
block tin, nickel silver, polished steel or metal, and lined with fluted glass with
deep furrows.
In order that my said Invention may be more readily understood, I will describe
the accompanying sheet of drawings.-Fig 1. represents a plan view of a group of
lamps arranged according to my Invention. Fig. 2 is a vertical section on line 3. c.
fig. 1. Fig. 3 is a full-size plan view of my improved burner; and Fig. 4 is a view
partly in section of same. In figs. 1 and 2 A shows the reservoir; B. B., the_lamps
attached to and communicating with same by means of pipes a. a. The reflectors
are shown by the point or triangular pieces C. C. which are attached to the reservoir
and act on the light emitted by the flames of the burner in the manner herein before
described. The wicks are operated by the thumb-screws b. b. In fig. 2 e. e. indicates
the stopper through which the oil is supplied to the reservoir; and for the purpose
of indicating the depth at which the oil stands I introduce the float arrangement
seen at ff. The segmental and flat wicks herein before referred to are shown in
Fig. 3, while fig. 4 shows at h. h. inlets for admitting air underneath the burner, by
which means I cause a current of air to pass around the wick between the oil and
the burner thereby deriving the advantages hereinbefore described.
It is obvious that any number of my improved burners can be fitted to the reservoir
as herein proposed to be used.

page_text: Having thus described my said Invention and the manner of applying same
I would have it understood that what I consider new and useful and therefore
claim as the Invention to be secured to me by the hereinbefore in part recited
Letters Patent is:-
1stly. The combination formed by the arrangement of lamp, reflectors, and
reservoir, substantially for the purpose and in the manner herein specified and set
forth.
2ndly. The employment of a segmental and flat wick in combination substantially
in the inauner described.
3rdly. The use of the inlets h. h. in fig. 4 for the purpose of admitting air
substantially in the manner and for the purpose described.
In Witness whereof, I, the said, Patrick Molloy, have hereunto set my hand
and seal this twenty third day of August, in the year of Our Lord, One
thousand, eight hundred and eighty two.
