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 LAMPS." -A-communication from abroad
by Samuel Holmes, of New York City, United States of America.
Sealed the 3rd October 1862, and dated the 30th April 1862.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
30th 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 LAMPS," to be as follows:-
This Invention of improvements in lamps consists of a new and improved
mode of securing the glass or other chimney to the cone, and the cone to the
burner, so as to allow the chimney to expand (as it heats) without breaking,
and so as to admit of the cone being firmly secured to the burner and the
chimney and cone easily removed without touching the chimney with the hand
when it is desired to reach the wick. For this purpose the cone is made to
fit loosely on the burner within its upper part, and a radial arm is attached to
the base of the cone and projects from the cone and passes through or is
fitted into a recess in the top of the burner. To the outer end of this arm an

page_text: elastic plate, which is equal in length to the arm, is secured by means of a
rivet. This elastic plate is curved slightly upward at its inner end. The plate
can turn freely on the rivet, and when in its proper place it is directly over the
arm of the cone. Two hooks are placed as the base of the cone and catch
over the flange at the lower end of the chimney, and this flange also fits
underneath the end of the elastic plate. The elastic plate and the hooks
firmly secure the chimney to the cone, and the plate allows the chimney to
expand when heated without the hooks themselves being required to yield.
Another elastic plate is attached to the outer end of the arm; this is larger
than the first plate, and projects some distance beyond the outer end of the
arm and a short distance beyond its inner end. This larger plate may be
secured on the same rivet as the other, and turns on the rivet so as to fit
under the inner edge of the burner, and thus it secures the cone and chimney
to the burner, the base of the cone fitting under a hook at the upper edge of
the burner.
a
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 30th 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 Thirtieth 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 Inven-
tion for "IMPROVEMENTS IN LAMPS," being a communication from abroad by
Samuel Holmes, of New York City, upon the condition (amongst others) that
I, the said William Edward Newton, by an instrument in writing under my

page_text: 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
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 Lamps" relates to a new and improved
mode of securing the chimney to the cone and of securing the cone to the
burner, whereby the chimney is allowed to expand as it heats, and is thereby
prevented from breaking or fracturing, a result which would occur if a rigid
or unyielding chimney were employed. The Invention at the same time
admits of the cone being firmly secured to. the burner and serving as a handle
to allow of the chimney and cone being removed from the burner while hot,
so that the wick tube may be exposed and the wick trimmed with facility at
any time.
In the accompanying Drawing, Fig. 1 is a vertical central section of the
upper part of a lamp; Fig. 2 is a detached plan or top view of the cone of
the burner with the clamp and catch detached; Fig. 3 is a plan or top view
of the burner.
.
A represents the burner, which may be constructed in any of the forms used
for burning coal oil; B is the wick tube, and C the cone, which fits loosely on
the burner A; within its upper part, and to the base of the cone C, there is
attached a radial arm D, which projects outward a suitable distance from the
cone, and passes through or is fitted in a recess a in the top of the burner,
To the outer end of this arm D, on its upper surface, there is secured by a
rivet b an elastic plate E, which is equal in length to the arm D, and is curved
slightly upward at its inner end, as shewn in Fig. 1. The plate E is allowed
to turn easily on its rivet b, and when in use or performing its proper function
this plate is also fitted in the recess a of the burner, and is consequently
directly over the arm D of the cone. To the base of the cone C, and at the
side opposite to the arm D, there are attached or formed two hooks c, c,, which
are designed to catch over the flanch at the lower end of the glass chimney,
which is indicated by dotted lines in Fig. 1, and this flanch also fits underneath
the inner end of the elastic plate E, between it and the arm D, as shown in
Fig. 1.
This elastic plate E it will be seen presses down on the top of the

page_text: plate E to its
flanch, and in connection with the hooks c, c, firmly secures the chimney to
the cone. The plate E it will also be seen admits of the chimney freely
expanding while heating, as the flanch of the chimney as the latter expands
merely extends or spreads outward underneath the plate E, the side of the
chimney not being allowed to come in contact with the inner end of the plate.
This will be fully understood by referring to Fig. 1. The hooks c, c, do not
require to be yielding, a free movement or expansion at one side of the chimney,
as at the plate E, being sufficient to prevent fracture. To the outer end of
the arm D, at its under side, there is attached an elastic plate F, which may be
secured to the arm D by the same rivet 6 which secures the
upper surface. The plate F is somewhat larger than E, and projects some
distance beyond the outer end of the arm D, and also projects a trifle beyond
its inner end; the plate F, like E, is elastic, and is also allowed to turn on
the rivet b, and when adjusted, in line with the arm D, its inner end fits under
the lower edge or part of the burner A, as shewn in Fig. 1, and secures the
cone and chimney to the burner, the base of the cone C, at a point opposite to
the arm D, fitting under a hook d at the upper edge of the burner, as seen in
Fig. 3. From the above description it will be understood that in order to
attach the chimney to the cone C, the flanch at the bottom of the chimney
is inserted under the hooks c, c, of the cone, and the elastic plate E is then to
In order
be turned over the flanch, so as to bring it in line with the arm D.
to secure the cone C and chimney to the burner, the cone is fitted in the
burner underneath the hook d, Fig. 3, and the elastic plate F is turned so
that its inner edge will catch under the bottom of the burner, as shown in
Fig. 1. In order to detach the cone and chimney from the burner all that is
required is to grasp the end of the arm D, or rather the outer ends of the
plates D, E, and turn the elastic plate F to one side so as to remove its inner
end from underneath the burner. The cone with the chimney attached may
then be readily removed, however warm or hot the chimney may be. The
wick tube consequently may be exposed, and the wick rendered accessible at
any time for trimming and lighting the lamp. By this arrangement the
operator will not be compelled to touch the chimney while removing it from
the burner and replacing it thereon, and the arm D and plates E, F, are
never sufficiently warm to prevent being handled and adjusted in the way and
for the purpose specified.
Having now described the Invention of "Improvements in Lamps" as
communicated to me by my foreign correspondent, what I claim as new and
desire to secure by Letters Patent is, the removeable cone C, provided with the

page_text: hooks c, c, and arm D, in combination with the elastic adjustable plates E, F,
attached to the arm, and arranged in relation with each other and respectively
with the chimney and burner A for the purpose and as herein set forth.
In witness whereof, I, the said Willian Edward Newton, have hereunto
set my hand and seal, the Thirtieth day of October, in the year of
our Lord One thousand eight hundred and sixty-two.
