I. GEORGE BARKER of 77 Colmore Row Birmingham in the County of Warwick
Consulting Engineer & Patent Agent do hereby declare the nature of the said
invention as communicated to me from abroad by James P. Bixby of Saint Stephen
in the province of New Brunswick in the Dominion of Canada.
My invention has for its object improvements in argand lamps and consists of an
oil reservoir having a tube passing up through the centre for the passage of air to
the burner which is at the top.
An adjustable rod which passes up the centre is mounted in guide bars so as to
slide up and down and carries at the top a removeable disc for spreading the flame, so
that by adjusting the rod from below the reservoir the disc will regulate the volume
of flame or the flame will be wholly extinguished when the disc is drawn down
against the top of the wick. A second tube surrounds the first tube and covers the
wick when raised and is supported by attachment to a cover removeably, bearing on
the top of the reservoir and confined laterally by an annular rim surrounding the
opening through which the first mentioned or inner tube, passes through which
opening the oil is fed and the rim also prevents the overflowing oil from trickling
down the lamp. A chimney holder perforated at the base and seated on a perforated
bearing is secured to the outside of the second mentioned or outer tube the perforations
allowing air to pass, within the chimney to assist combustion. A removeable, truncated
cone is seated on the base of the chimney holder to concentrate and thereby increase
the air current and induce perfect combustion. A removeable perforated inverted
cone is supported in the inner tube near the top to equalize the draft of the flame
and a tubular wick holder slides on the outside of the inner tube to sleeve the wick
on to the holder. An arm is attached to the wick holder and is connected with a
rod which passes through a slot in the top of the reservoir and cover to raise and
lower the wick.
A perforated thimble flame spreader is inserted within the inner tube at the top for
optional use when the disc and cone are removed, and the reservoir stands upon a
perforated base for the purpose of allowing air ingress to the inner tube.
Dated this 6th day of September 1888.

1 GEORGE BARKER of 77 Colmore Row Birmingham in the County of Warwick,
Consulting Engineer & Patent Agent do hereby declare the nature of the said
invention as communicated to me from abroad by James P. Bixby of St. Stephen
in the province of New Brunswick in the Dominion of Canada.
My invention has for its object improvements in argand lamps and consists of an
oil reservoir having a tube passing up through the centre for the passage of air to
the burner which is at the top. An adjustable rod which passes up the centre is
mounted in guide bars so as to slide up and down and carries at the top a removable
disc for spreading the flame so that by adjusting the rod from below the reservoir the
disc will regulate the volume of flame or the flame will be wholly extinguished when
the disc is drawn down against the top of the wick. A second tube surrounds the
first tube and covers the wick when raised and is supported by attachment to a
cover removeably bearing on the top of the reservoir and confined laterally by
an annular rim surrounding the opening through which the first mentioned or inner
tube passes through which opening the oil is fed and the rim also prevents the
overflowing oil from trickling down the lamp. A chimney holder perforated at the
base and seated on a perforated bearing is secured to the outside of the second
mentioned or outer tube the perforations allowing air to pass within the chimney to
assist combustion. A removeable truncated cone is seated on the base of the chimney
holder to concentrate and thereby increase the air current and induce perfect
combustion. A removeable perforated inverted cone is supported on the inner tube
near the top to equalize the draft of the flame and a tubular wick holder slides on the
outside of the inner tube to sleeve the wick on the holder. An arm is attached to
the wick holder and is connected with a rod which passes through a slot in the top
of the reservoir and cover to raise and lower the wick.
A perforated thimble flame spreader is inserted within the inner tube at the top for
optional use when the disc and cone are removed, and the reservoir stands upon a
perforated base for the purpose of allowing air ingress to the inner tube.
In order that my invention may be clearly understood and more easily carried
into practice I have appended hereunto a sheet of drawings upon which I have
shewn a vertical sectional elevation of one of my improved lamps. X is the oil
reservoir in the centre of which is supported a through tube B for passage of air
to the burner at the top. A is an adjustable rod sliding in guide bars C. C. across
the inside of the tube B and the said rod carries at the top a removeable disc L for
spreading the flame so that by adjusting the rod from below the reservoir, the disc
will regulate the volume of flame, or the flame will be wholly extinguished when the
disc is drawn down against the top of the wick.
D is a tube surrounding the tube B and covers the wick when raised and is
supported by attachment to a cover E removably bearing on the top of the reservoir
and confined laterally by an annular rim T. Surrounding the opening N through
which the tube B passes and into the said opening N the oil is fed and the rim also
confines the overflow of oil from trickling down the lamp..

page_text: F is a chimney holder perforated at the base and seated on a perforated bearing U
secured to the outside of the tube D the perforations allow air to pass within the
chimney to assist combustion. S is a removeable truncated cone seated on the base
of the chimney holder F to concentrate and thereby increase the air current, and
induce perfect combustion.
G is a removeable perforated inverted cone supported in the tube B near the top
to equalize the draft of the flame.
His a tubular wick-holder sliding on the tube B and the wick is sleeved on the
holder.
J is an arm attached to the wick holder H and connects with a rod K which passes
through a slot in the top of the reservoir X and cover E to raise and lower the
wick.
R is a perforated thimble flame spreader for optional use to be inserted in the
tube B at the top when the disc L and the cone G are removed. The reservoir X
stands on a perforated base P to allow air ingress to the tube B.
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.
First. The combination with the reservoir X having a central tube B of the
removeable cover E, tube D, chimney-holder F and truncated cone S as set forth for
the purposes described.
Second. The combination with the tube B of the adjustable rod A carrying disc L
and a perforated truncated cone G as set forth for the purposes described.
Third. The combination with the reservoir X having the tube B of the wick-
holder H having an arm J and connected to a rod K passing out through the top of
the reservoir to lift and depress the wick as set forth.
Fourth. The reservoir X having an opening N around the tube B and a rim T
surrounding the opening in combination with a removeable cover E and tube D as
and for the purposes set forth.
Fifth. An Argand Lamp consisting of the reservoir X provided with a rim T and
perforated base P an air tube B passing through an enlarged opening N in the top
of the reservoir, a tube D surrounding the tube B and attached to a removeable
cover E seated on the reservoir a chimney-holder F having a truncated cone S seated
therein, wick-holder H raised by a rod K passing through the top of the reservoir,
an adjustable rod A carrying a disc L to spread the flame and a cone G supported in
the air tube as set forth and described.
