IMPROVEMENTS IN WICK HOLDERS OR BURNERS FOR LAMDO
Year: 1865

page_text: LETTERS PATENT to Emil Wild and Wilhelm Wessel, of the Firm of
Wild and Wessel, Manufacturers, of Berlin, in the Kingdom of Prussia,
for the Invention of "IMPROVEMENTS IN WICK HOLDERS OR BURNERS FOR
LAMDO."
Sealed the 30th January 1866, and dated the 4th August 1865.
PROVISIONAL SPECIFICATION left by the said Emil Wild and Wilhelmi
Wessel at the Office of the Commissioners of Patents, with their
Petition, on the 4th August 1865.
We, EMIL WILD and WILHELM WESSEL, of the Firm of Wild and Wessel,
Manufacturers, of Berlin, in the Kingdom of Prussia, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN WICK HOLDERS OR BURNERS
FOR LAMPS," to be as follows:
This Invention consists in forming the wick holder of a circular shape,
larger at the bottom than at the top, and leaving in the bottom a wide gap,
which gradually lessens upwards. This arrangement enables a flat wick to
be formed into a round one without inconvenience, or in any way preventing
the free circulation of air required for perfect combustion. For moving this
.circular wick up and down a simple pinion in contact with it is employed,
instead of the rack and pinion at present in use.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Emil Wild and Wilhelm Wessel in the Great Seal Patent
Office on the 3rd February 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ЕMIL
WILD and WILHELM WESSEL, of the Firm of Wild and Wessel, Manufacturers,
of Berlin, in the Kingdom of Prussia, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fourth day of August, in the year of our Lord One
thousand eight hundred and sixty-five, in the twenty-ninth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
Emil Wild and Wilhelm Wessel, Her special licence that we, the said Emil
Wild and Wilhelm Wessel, our executors, administrators, and assigns, or
such others as we, the said Emil Wild and Wilhelm Wessel, our 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 WICK HOLDERS OR BURNERS
POR LAMPS," upon the condition (amongst others) that we, the said Emil Wild
and Wilhelm Wessel, our executors or administrators, by an instrument in
writing under our, 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.
NOW KNOW YE, that we, the said Emil Wild and Wilhelm Wessel, do
hereby declare the nature of our 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, reference being had to the Figures on the
accompanying Sbeet of Drawings, and to the letters of reference marked
thereon (that is to say) :-
This Invention consists in forming the wick holder of a circular shape,
larger at the bottom than at the top, and leaving in the bottom a wide gap,
which gradually lessens or tapers upwards. This arrangement enables a flat
wick to be formed into a round one without inconvenience, or in any way
preventing the free circulation of air required for perfect combustion. For
moving this circular wick up and down a simple pinion in contact with it is
employed, instead of the rack and pinion at present in use.

page_text: In the accompanying Figures a represents the wick holder; b, the taper
gap; and c, the pinion for raising and lowering the wick.
It will be readily seen that a flat wick entered from below and passed
upwards will become gradually curved, until at the top it is round, thereby
obtaining all the advantages of a circular wick, and allowing sufficient space
at the bottom for the passage of an ample supply of air, and at the same time
avoiding the necessity of having circular wicks slit at their lower ends and
fastened by threads.
Having now described the nature and particulars of our said Invention,
and the manner in which the same is to be performed or carried into effect,
we desire it to be understood that we claim the improved wick holders or
burners for lamps as herein described and illustrated in the accompanying
Sheet of Drawings.
In witness whereof, we, the said Emil Wild and Wilhelm Wessel,
have hereunto set our hands and seals, this Twenty-sixth day of
January, in the year of our Lord One thousand eight hundred and
sixty-six.
