for the Invention of "IMPROVEMENTS IN LAMPS, ESPECIALLY DESIGNED FOR

PROVISIONAL SPECIFICATION, left by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition, on the 7th
April 1862.
I, GEORGE HASELTINE, of the "International Patent Office," No. 100, Fleet
Street, in the City of London, American Barrister, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN LAMPS, ESPECIALLY
DESIGNED FOR BURNING HYDROCARBON OILS," being a communication to me from
abroad by Anson Platt, M.D., and General William, Rosecrans, both of
Cincinnati, Ohio, in the United States of America, to be as follows:-
:. These improvements are applicable to lamps for burning the ordinary
animal and vegetable oils, but they are particularly designed for burning those
oils which require a large supply of oxygen to produce complete combustion,
such as the coal oils. ¡

page_text: The first part of said Invention consists in an improvement on the Argand
burner, by which complete combustion is effected without a "button," and
with a short chimney not exceeding three inches in length. Instead of the
cylindrical wick tube of the Argand burner, several tubes are employed being
arranged concentrically in the form of a truncated cone, the upper ends nearly
touching one another, and the lower ends being considerably separated, so as to
admit a free access of air inside. And instead of the common "button" an
inverted conical deflector is employed, placed concentrically within the space
formed by the wick tubes. This arrangement makes a practicable portable
coal-oil lamp.
The second part of the said Invention consists in the use of separate
serrated wheels for raising and adjusting the wick independently of each
other.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Haseltine in the Great Seal Patent Office on the
7th October 1862.
..TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," No. 100, Fleet Street, in
the City of London, American Barrister, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letter's
Patent, bearing date the Seventh day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said George Haseltine, Her special licence, that I, the said George Haseltine,
my executors, administrators, and assigns, or such others as I, the said George
Haseltine, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might makė, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
LAMPS, ESPECIALLY DESIGNED FOR BURNING HYDROCARBON OILS," a communication,
from abroad by Anson Platt, M.D., and General William Rosecrans, both of
Cincinnati, Ohio, in the United States of America," upon the condition
(amongst others), that I, the said George Haseltine, my executors or adminis-
trators, by an instrunient in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the said

page_text: Invention, and in what manner the same was to be performed, and cause;
the same to be filed in the Great Seal Patent Office within six calendar;
months next and immediately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
the nature of my said Invention, and in what manner the same is to be.
performed to be particularly described and ascertained in and by the following
statement; reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say):-
These improvements are applicable to lamps for burning the ordinary:
animal and vegetable oils, but they are particularly designed for burning,
those oils which require a large supply of oxygen to produce complete com-
bustion, such as the coal oils.
1
The first part of said Invention consists in an improvement on the " Argand
burner," by which complete combustion is effected without a "button," and
with a short chimney not exceeding three inches in length. Instead of the.
cylindrical wick tube of the "Argand burner". several tubes are employed,
being arranged concentrically in the form of a truncated cone, the upper ends
nearly touching one another, and the lower ends being considerably separated,
so as to admit a free access of air inside. And instead of the common
" button an inverted conical deflector is employed, placed centrally within.
'the space formed by the wick tubes. This arrangement makes a practicable.
portible coal-oil lamp..
"
The second part of the said Invention consists in the use of separate.
serrated wheels for raising and adjusting the wicks independently, of each
other.
In order that the said Invention may be fully understood, and readily.
carried into effect, I will proceed to describe the Drawing hereunto annexed. :
DESCRIPTION OF THE DRAWING.
Figure 1 is a side view of the lamp; Figure 2 is a vertical section of the
same; Figure 3 is a plan view of the top of the burner; Figure 4 is a
horizontal section through the wick tubes and serrated wheels.
C, Figure 1, is the lamp, pedestal, and stand; B, Figures 1 and 2, is the
reservoir for holding the oil; D, Figure 1, is a metal ring or band cemented:
to the reservoir or body of the lamp;. A, Figures 1 and 2, is the casing or.
exterior of the burner; E is a short chimney about two inches and one-half
in height, more or less; c, c, c, c, are the wick tubes, shewn in Figures 1, 2,
and 3; d, Figure 2, is an inverted truncated metal cone or deflector; b, b,
Figures 1, 2, and 4, are serrated wheels for adjusting the wicks; F, Figure 1,
:

the connection between the body of the lamp and the burner casing; f, Figure 4,
is the space between the wick tubes at their lower ends; i, Figure 3, is the
space between these tubes at their upper ends; g, Figure 2, is the space
between the wick tubes and the deflector d.
'
CONSTRUCTION AND OPERATION..
The pedestal and stand C are constructed of any suitable material and shape
to support the lamp. The reservoir B is secured to the pedestal C in any
convenient manner. The ring or band D is cemented to the reservoir or body
of the lamp. The burner casing is secured to this band by means of a screw
cut upon the lower part of this casing fitting into a female screw cut on the
said band. The oil is supplied to the reservoir through the aperture in the
band D. The wick tubes c, c, c, c, are arranged concentrically, as shown in'
Figures 3 and 4. These tubes converge towards their upper ends, as shewn in
Figure 2. In the centre of the burner casing is fixed an inverted truncated
metal cone d, Figure 2; b, Figures 1 and 2, and 4, are serrated wheels, by.
means of which the wicks are separately adjusted to the required height. These
wheels extend through the burner casing A, so that the teeth on the inside.
take hold of the wicks, while the outside project sufficiently beyond the casing
to enable the wheel to be turned by the fingers. The short chimney E is
fastened to the casing of the burner by means of the band F, or by means of
any other suitable and convenient device. By this construction and arrange
ment of the wick tube, several wicks being used instead of one, as in ordinary
lamps of this description, I obtain complete combustion with a chimney about
two and one-half inches in length, more or less, thereby rendering the lamps
more convenient and portable than those heretofore invented for burning coal
oil and other similar materials. This perfect combustion is secured by
bringing a large amount of oxygen to the flame through openings a, a,
Figure 2, in the direction of the arrows shewn on the same Figure, between
the wick tubes c, c, at f, f, Figure 4, and thence up through the space g,
Figure 2, coming in contact with the flame at the top.
Having fully described and ascertained the nature of my said improvements,
and a manner of carrying the same into effect, what I claim as my Invention,
and desire to secure by said Letters Patent, is,―
(1.) The combination of the concentric tubes c, c, c, c, converging upward,
and the deflector d, having the form of an inverted cone, substantially in the
manner and for the purpose herein specified.
(2.) I claim the arrangement of the separate serrated wheels b, b, b, b,

page_text: extending respectively from said tubes outward just through the casing A,
substantially as herein set forth.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and seal, this Sixth day of October, in the year of our
Lord One thousand eight hundred and sixty-two.
GEORGE HASELTINE. (L.S.)
