page_text: LETTERS PATENT to John Dent Goodman, of Birmingham, in the
County of Warwick, for the Invention of "IMPROVEMENTS IN
LANTERNS "A communication.
Sealed the 22nd September 1858, and dated the 20th July 1853.
PROVISIONAL SPECIFICATION left by the said John Dent Good-
man at the Office of the Commissioners of Patents, with his
Petition, on the 20th July 1858.
I, JOHN DENT GOODMAN, of Birmingham, in the County of Warwick,
do hereby declare the nature of my Invention for "IMPROVEMENTS IN
LANTERNS to be as follows:-
This Invention consists of constructing the glass which receives the
oil or fluid, and the glass of the upper part which transmits the light,
all in one piece. For this purpose there is a partition of glass formed
between the upper and lower compartments of the lantern, in which
partition is an opening to receive the wick tubes or burner. The lantern
has a metal perforated top, and, when desired, reflectors and wire guard
or framing.

Office, on the 17th January 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I.
JOHN DENT GOODMAN, of Birmingham, in the County of Warwick,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of July, in the year of
our Lord One thousand eight hundred and fifty-three, in the seventeenth
year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said John Dent Goodman, Her special licence
that I, the said John Dent Goodman, my executors, administrators,
and assigns, or such others as I, the said John Dent Goodman, ny
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," communicated to me from abroad, upon
the condition (amongst others). that I, the said John Dent Goodman,
by an instrument in writing under my hand and seal, should parti-
cularly 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 John Dent Goodman, 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 thereof (that is to say):
This Invention consists of constructing the glass which receives the
oil or fluid, and the glass of the upper part which transmits the light.
all in one piece. For this purpose there is a partition of glass formed
between the upper and lower compartments of the lantern, in which
partition is an opening to receive the wick tubes or burner. The lantern

page_text: has a metal perforated top, and, when desired, reflectors and wire guard
or framing.
Having thus stated the nature of the said Invention, I will proceed
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1, shows a glass lantern constructed according to the Inven-
tion; Figure 2, is a vertical section; and Figure 3, a plan thereof.
This lantern has no guards or wire framing to protect it; and Figures.
4, 5, and 6, show respectively an external view, a plan, and a vertical
section of a similar lantern, having a guard or framing to protect the
saine when subjected to rough usage. In each of these Figures the same
letters indicate similar parts. a, a, being the lantern of glass, which,
though made in one piece, is divided into two compartments by a par-
tition a', of glass, there being an opening at a², to receive a burner
tube or tubes b, to carry the wicks, a ring of metal c, being cemented
into this opening a, to receive the burner tubes, which may be of any
ordinary construction. The form or configuration of the glass lantern
is that which is found to be generally preferred, but the same may be
varied so long as the whole, with the dividing partition, be made of glass,
and, when finished, of one piece, that is, having no metal or other non-
transparent means of joining the oil vessel to the upper glass. c', is the
metal cap or cover, which is hinged at one side to a metal rim formed
on the bead at the upper part of the glass vessel a, and the cap is
retained closed by a spring catch d, at the other side, as shewn; e, is
the handle, by which the lantern is carried or suspended; f, is a framing
of wire to protect the lantern; the form of these parts may be varied,
and, separately, I make no claim to the frame cover or handle.
By this construction and arrangement it will be seen that the oil or
matter to be burned is placed in the lower compartment of the lantern
at, and by reason of the partition or division a', between the upper and
lower parts of the lantern being of glass, and of one piece with the upper
and lower parts of the vessel a, it, as well as the lower compartment or
oil vessel, will admit of the passage of light.
Having thus described the nature of the said Invention, and the

page_text: manner of performing the same, I would have it understood that what
I claim is, the manufacture of glass lanterns herein described.
In witness whereof, 1, the said John Dent Goodman, have here-
unto set my hand and seal, this Seventh day of January, in the
year of our Lord One thousand eight hundred and fifty-four.
Witness,
Tnos V. MACREADY.
