PROVISIONAL SPECIFICATION left by the said John William Gregg
at the Office of the Commissioners of Patents, with his Petition, on
the 19th February 1872.
I, JOHN WILLIAM GREGG, of Great Brunswick Street, in the City of
Dublin, Alderman, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN PARAFFIN AND OTHER LANTERNS AND LAMPS," to be as
follows:-
This Invention relates to lanterns or lamps for burning paraffin or
other oils, and is chiefly applicable to street, railway, and out-door lamps.
It consists in attaching to one side of the lower portion of the frame
of the lamp on the outside a small oil cistern or reservoir, capable of
holding a supply sufficient for eight to twelve hours' burning. The

page_text: cistern is made of metal, and extends around or across or part way
around or across the bottom of the lamp. There is a small tube leading
from this cistern or reservoir in connection with a wick holder or burner
of the usual construction in the middle of the lamp.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John William Gregg in the Great Seal Patent
Office on the 17th August 1872.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
WILLIAM GREGG, of Great Brunswick Street, in the City of Dublin,
Alderman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of February, in the year
of our Lord One thousand eight hundred and seventy-two, in the
thirty-fifth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said John William Gregg, Her special
license that I, the said John William Gregg, my executors, adminis-
trators, and assigns, or such others as I, the said John William Gregg,
my executors, administrators, or 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 "IMPROVE-
MENTS IN PARAFFIN AND OTHER LANTERNS AND LAMPS," upon the condition
(amongst others) that I, the said John William Gregg, my executors or
administrators, 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 John William Gregg, 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, that is to say :-

page_text: My said Invention relates to lanterns or lamps for burning paraffin
or other oils, and is applicable to railway carriage, street, or other out-
door lamps.
It consists in attaching to the lower portion of the framework of any
lantern or lamp a reservoir outside of same for holding the oil or spirit.
This reservoir supplies the burner inside the lamp or lantern by means
of a cupped, side, or horizontal arm to which it is attached. The
reservoir will hold a supply of oil or spirit for eight hours' consumption,
but can be increased in size for twelve or fourteen hours' supply without
casting a shadow. The burner in the centre of the lamp may be made
to receive a round or flat wick, and is moved or adjusted by means
of a spiral thread, or a rack and pinion movement.
The lantern or lamp has a white earthenware, china, or opal glass
shade on the top, and also when used as a bracket lamp a similar reflector
at the back of the burner.
Having now described and particularly ascertained the nature of my
said Invention, and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that what I consider
to be novel and original, and therefore claim as the Invention secured
to me by the herein-before in part recited Letters Patent is, the peculiar
construction and arrangement of paraffin or other lanterns or lamps as
herein-before described.
In witness whereof, I, the said John William Gregg, have to this
my Specification set my hand and seal, this Fourteenth day of
August One thousand eight hundred and seventy-two.
