IMPROVEMENTS IN LANTERNS
Year: 1860

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 LANTERNS."-A communication from
abroad by Nathaniel Tufts, junior, of Boston, Augustus Tufts, of Malden,
Middlesex County, Massachusetts, and Simon G. Cheever, of Boston,
all in the United States of America.
Sealed the 23rd November 1860, and dated the 17th September 1860.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on
the 17th September 1860.
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 LANTERNS," to be as follows:-
The kind of lantern upon which the improvements are made are those con-
sisting of a cylinder of glass formed with a series of zones or belts extending
horizontally around the exterior of the lantern, the object of these zones being
to effect in appearance elongation of the flame in a vertical direction. The
improvements consist in constructing a lantern not only with a series of
horizontal belts or zones with angular or inclined sides on the exterior of the
glass cylinder,but also with a series of vertical refracting ribs or angleson the
interior of the lantern, whereby the lights produced will not only be elongated,
[Price 8d.]

page_text: but their number will be apparently doubled, producing, for instance, four
lights, where there are but two flames or burners. It will be understood that
the essential feature of the Invention is the combination in a glass lantern of a
series of horizontal refracting zones or belts formed on the exterior of the
lantern, with a series of vertical ribs formed on the interior thereof, whereby
the lights are both multiplied and elongated, the great advantage of which in
adding to the quantity of light and the diminution in expense will be apparent.
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 16th March 1861.
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 Seventeenth day of September, in theyear of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reiga, 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 LANTERNS," 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
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) :-

page_text: The kind of lanterns upon which the improvements constituting the
present Invention are made are those consisting of a cylinder of glass
formed with a series of zones or belts extending horizontally around the
exterior of the lantern, the object of these zones being to effect in appear-
ance the elongation of the flame in a vertical direction. The improvements
consist in constructing a lantern not only with a series of horizontal belts
or zones with angular or inclined sides on the exterior of the glass cylinder,
but also with a series of vertical refracting ribs or angles on the interior of
the lantern, whereby the lights produced will not only be elongated, but
their number will be apparently doubled, producing, for instance, four lights
where there are but two flames or burners, the great advantage of which in
adding to the quantity of light and the diminution in expence will be apparent.
In the accompanying Drawing Fig. 1 is a central vertical section of a
lantern constructed according to the present improvements; and Fig. 2 is
a horizontal section taken in the line A, B, of Fig. 1.
a, a, a, represents the cylinder of a lantern, having formed on its exterior
bevilled or angular zones or belts b,b, extending horizontallyaround the same,
as seen in Fig. 1, and vertical bevilled ribs d, d, on the inside of the same,
as shewn in Fig. 2; e, e, is the lamp, which may be provided with any
desired number of burners f, f. By this arrangement while the lights pro-
duced are elongated, they will also be apparently doubled in number.
Having now described the improvements in lanterns that constitute the
Invention that has been communicated to me by my foreign correspondent,
I claim as the Invention secured to me by Letters Patent as aforesaid, the
application to lanterns of a glass cylinder constructed with a series of hori-
zontal refracting zones or belts formed on the exterior of the lantern, and
with a series of vertical ribs formed on the interior thereof, whereby the
lights are both multiplied and elongated, as set forth.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, the Fifteenth day of March, in the year of
our Lord One thousand eight hundred and sixty-one.
Witness,
J. W. MOFFATT,
66, Chancery Lane.
