Year: 1874

page_text: LETTERS PATENT to Emil Kauffmann, of 21, Red Lion Square, in the
County of Middlesex, for the Invention of "IMPROVEMENTS IN LAMP
aww-w
BURNERS." A communication from abroad by C. A. Kleemann, of.
Erfurt, in the Kingdom of Prussia.
Scaled the 21st August 1874, and dated the 10th June 1874.
PROVISIONAL SPECIFICATION left by the said Emil Kauffmann' at
the Office of the Commissioners of Patents, with his Petition, on
the 10th June 1874.
I, Emil KauffMANN, of 21, Red Lion Square, in the County of
Middlesex, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LAMP BURNERS," to be as follows:-
This Invention relates to an arrangement whereby a wick folded and
introduced in a flat form at the bottom of the burner is converted into a
round wick at or near the point where combustion takes place, and
consists of a body or outer cylindrical case, the upper part of which is
made taper.
At the base of the burner is a slot or opening having one,

page_text: two, or more serrated or pinion wheels projecting within it. Above the
wheels is fixed a curved hollow tube, which is wedge-shaped at its lower
part, but concentric with the outer case at its upper extremity, and has
an opening near its bottom for admission of air to the interior of the
flame. When the flat wick is doubled and introduced to the slot, and
the pinions turned, the wick is forced upwards against the inner tube,
which by reason of its wedge shape opens or divides the wick, and by
the progressive movement caused by continuing to turn the pinions the
wick is compelled to assume a cylindrical form at the top of the
burner.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Emil Kauffmann in the Great Seal Patent Office
on the 10th December 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, Emil
KAUFFMANN, of 21, Red Lion Square, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of June, in the year of
our Lord One thousand eight hundred and seventy-four, in the thirty-
seventh year of Her reign, did, for Herself, Her. heirs and successors,
give and grant unto me, the said Emil Kauffmann, Her special license,
that I, the said Emil Kauffmann, my executors, administrators, and
assigns, or such others as I, the said Emil Kauffmann, 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
LAMP BURNERS," upon the condition (amongst others) that I, the said
Emil Kauffmann, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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.

the toothed wheels the wick is compelled to assume a cylindrical form
at the top of the burner.
Having now described and particularly set forth the nature of this
Invention and the manner in which the same is or may be used or
carried into effect, I would observe in conclusion that I do not confine
or restrict myself to the precise details or arrangements which I have
described or referred to, as variations may be made therefrom without
deviating from the principles or main features of this Invention; but
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 construction of lamp burners as described and shown on
the Drawings, whereby a wick folded and introduced in a flat form is
converted into a practically round wick at the top of the burner.
In witness whereof, I, the said Emil Kauffmann, have hereunto
set my hand and scal, this Tenth day of December, in the
year of our Lord One thousand eight hundred and seventy-
four.
EMIL KAUFFMANN. (L.S.)
