Year: 1862

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for
the Invention of "IMPROVEMENTS IN CHIMNIES FOR LAMPS." - A commu-
nication from abroad by Harvey Brown, of New York City, United
States of America.
Sealed the 3rd October 1862, and dated the 25th April 1862.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
25th April 1862.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN CHIMNIES FOR LAMPS," to be
as follows:-
This Invention of improvements in chimnies for lamps is applicable to any
form of lamps for burning any description of oil or fluid that requires
chimnies to promote its combustion. The chimnies may be made in size and
form of attachment adapted to the lamps to which they are to be applied.
The lower part of the chimney is made of glass in a bulbous form, having a
ridge around it near the top, for the purpose of attaching the truncated cone
above. The top of this bulbous chimney reaches to about where the top of
the flame in the burner will come when in full operation. On the bottom of

page_text: this glass is made a ridge or projection for the purpose of attaching the
chimney to the lamp.
A truncated cone, made of tin, brass, or other sheet metal, with more or
less angle, is placed on the glass chimney, and attached thereto by means of
clamps, or any other suitable and convenient contrivance; a shade or reflector
of tin or other suitable material, in circular form, and set to an angle outward
and downward, rests on the bottom of the truncated cone, but can be easily
removed when desired; or it may be attached and remain there permanently
if preferred. This shade may be perforated with holes, more or less in
number and size, if desired.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great Seal Patent Office
on the 25th October 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
EDWARD
NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth 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 William Edward Newton, Her special license, that I, the said William
Edward Newton, my executors, administrators, and assigns, or such others as I,
the said William Edward Newton, 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 make,.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 CHIMNIES FOR LAMPS," being a communication from abroad,
upon the condition (amongst others) that I, the said William Edward Newton,
by an instrument in writing under my hand and seal, should particularly
describe and ascertain the nature of the, said 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 William Edward Newton, do hereby
declare the nature of the said Invention, and in what manner the same is

page_text: 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) :-
This Invention of improvements in chimnies for lamps is applicable to any
form of lamps for burning any description of oil or fluid that requires chimnies
to promote its combustion. The chimnies may be made in size and form of
attachment adapted to the lamps to which they are to be applied.
In the accompanying Drawings, Fig. 1 is a side elevation; Fig. 2, a bird's
eye or top view of the chimney without a shade; Fig. 3 is a plan view of the
shade; Fig. 4 represents the shade as attached to the chimney, and the two
combined as when in use. A is the glass bulb in the lower part of the chimney,
which has a ridge or protuberance B around or near the top of the bulb; C is
a truncated cone attached to the top of the glass bulb. The lower part of the
chimney is made of glass in a bulbous form, and has a ridge around it near
the top, for the purpose of attaching the truncated cone above. The top of
this bulbous chimney reaches to about where the top of the flame in the
burner will come when in full operation. On the bottom of this glass is made
a ridge or projection for the purpose of attaching the chimney to the lamp by
means of a screw, spring, or otherwise, as provided on the lamp. By means of
the truncated cone or other form the chimney is contracted from the base at
the glass bulb to the outlet of the tube. This truncated cone or tube is made
of tin, brass, or other sheet metal, with more or less angle, by which the
length is determined, leaving the orifice at the top about one inch, more or less,
as desired. This cone or tube is attached to the ridge B of the glass bulb by
means of clamps, or any other suitable and convenient means by which it is
firmly attached. A shade or reflector B', of tin or other suitable material, is
made in a circular form one inch or more wide, and set to an angle outward
and downward, of from thirty to forty-five degrees from the plane of the
horizon. The diameter of the orifice in this shade is equal to the outside of
the base of the cone, so that it may be easily dropped on and allowed to rest
there, and can be easily removed when desired; or it may be attached and
remain there permanently if preferred. This shade may be perforated with
holes, more or less in number and size, if desired, as shewn in Fig. 4.
This lamp chimney secures the brilliancy of the light produced by the use
of the glass chimney, and the metal cone and small shade combined secures
all the advantages of the ordinary large paper shade on the glass tube, and is
much more convenient, as it is perfectly portable, and can be used in-doors
or out, thereby becoming both lamp and lantern. These are some of the
advantages of this Invention.

page_text: Having now described this Invention of improvements in chimnies for
lamps, and having explained the manner of carrying the same into effect, as
communicated to me by my foreign correspondent, I claim as the Invention
secured to me by Letters Patent, as aforesaid,-
1st, the arrangement and construction of a lamp chimney having a glass
bulb for its base, with a sheet metal tube or cone attached, substantially in
the manner and for the purpose set forth.
2nd, I claim the use of and application to this lamp chimney of the
shade B', constructed and arranged substantially in the manner and for the
purposes set forth.
In witness whereof, I, the said William Edward Newton, have here-
unto set my hand and seal, this Twenty-fourth day of October, in the
year of our Lord One thousand eight hundred and sixty-two.
Witness,
J. W. MOFFATT,
