Complete Accepted, 27th Sept., 1887.
I, GRIFFITH BREWER of 33 Chancery Lane, in the County of Middlesex, Mechanical
Draughtsman do hereby declare the nature of this invention (a communication to
me from abroad by Luther Beckwith Wood, of Omaha, in the County of Douglas,
and State of Nebraska, United States of America, Carpenter) to be as follows:-
This invention relates to a lantern designed to burn lard-oil, or other heavy oil of
that class, in which means are employed for conducting heat from the flame of the
lantern to the oil for warming it in the cup or oil reservoir of the lantern.
The invention consists in the construction, arrangement and combination of parts,
all as hereinafter described.
The frame, globe, ventilating or draught top, and oil cup or reservoir, with base
may be of the usual or of any approved construction except that the oil cup is provided
with draught or heating tubes. The burner with the wick tubes, is also of ordinary
construction. The heating tubes are bent to form longer arms, and shorter arms, and
the said heating tubes are fitted in the top of the oil cup in such a manner that the
longer arms reach up to or into the draught top, and the shorter arms a short distance
above the top of the oil cup, thus leaving the fold or bend of the pipes enclosed in
the oil cup.
Upon the upper ends of the short arms are placed short pipes or tubes which may
be screwed on or otherwise movably attached to the short arms. The short pipes or
tubes are by preference enlarged or bell mouthed at their upper ends and passing
through the top of the oil cup are bent so as to stand nearly over the wick tubes so
that the heat from the flame of the lamp may be drawn into the short pipes by the
7

the oil cup. The said short tubes are made movable on the upper ends of the bent
arms by each being screw threaded, or the equivalent, so that the bell mouths can be
turned and adjusted opposite or at any angle to the flame as may be required, thus the
temperature of the oil may be regulated by turning the said tubes a greater or less
distance from the flame. In this manner the lantern is made to heat its own oil, so
that very heavy oil may be used in the lantern with very satisfactory results.
Dated this 26th day of November 1886.

I, GRIFFITH BREWER of 33 Chancery Lane in the County of Middlesex, Mechanical
Draughtsman, do hereby declare the nature of this invention (a communication to
me from abroad by Luther Beck with Wood, of Omaha, in the County of Douglas,
and the State of Nebraska, United States of America, Carpenter,) 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 a lantern designed to burn lard-oil or other heavy oil of
that class in which means are employed for conducting heat from the flame of the
lantern to the oil for warming it in the cup or oil-reservoir of the lantern.
The invention consists of the construction, arrangement, and combination of parts,
all as hereinafter described and claimed.
Reference is to be had to the accompanying drawings, forming part of this
specification, in which similar letters of reference indicate corresponding parts in all
the figures.
Figure 1 is a sectional elevation of a lantern having my invention applied thereto.
Fig. 2, is a detailed side elevation of a part of the same.
Fig. 3, is a sectional plan view taken on the line of Fig. 1, and Fig. 4 is a plan
view of the burner and oil cup or reservoir of the lantern.
The frame A, globe B, ventilating or draft top C, and oil cup or reservoir D, with
base D, may be of the usual or of any approved construction, except that the cup D
is provided with the draft or heating tubes E. The burner F, with the wick-tubes f, f,
is also of ordinary construction. The tubes E are bent to form the longer arms e and
shorter arms e¹, and the tubes E are fitted in the top d of the oil cup D in such a
manner that the longer arms e reach up to or into the draft-top C and the arms e¹ a
short distance above the top d.
Upon the upper ends of the arms e' are placed the short pipes or tubes bb, which
are by preference enlarged at their upper ends, as shown at c, and bent so as to stand
nearly over the wick-tubes f, so that heat from the flame of the lamp may be drawn
into the pipes b by the draft created by the long arms e of the tubes E, and pass
thence down into and through the tubes E and heat the oil contained in the oil-cup.
The temperature of the oil may be regulated by turning the tubes a greater or less
distance from the flame.
In this manner the lantern is made to heat its own oil, so that very heavy oil may
be used in the lantern with very satisfactory results.
I am aware that a lamp has been provided with a bent tube, the bent portion being
within the oil-chamber, the short arm of the tube having a bell-mouth extending over
the wick-tube, and I do not claim such, broadly, as of my invention.

page_text: Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :-
1. The combination, with a lantern, of the bent tubes E, consisting of the long
arms e, extending to the upper end of the lantern, the short arms e¹, extending above
the wick-tubes, substantially as set forth.
2. A lantern constructed with the bent tubes E, formed with long and short
arms e, e, the bent portions being within the oil-chamber, and the short curved pipes b,
held to turn on the short arms e, and having flaring mouths c, extending over the
wick-tubes, substantially as set forth.
