Year: 1864

page_text: LETTERS PATENT to Johann Ernst Friedrich Lüdeke, of 2, Stonefield
Street, Islington, N., and Daniel Wilckens, of 25, Union Square,
Great Dover Street, Borough, for the Invention of "IMPROVEMENTS IN
PROVISIONAL SPECIFICATION left by the said Johann Ernst Friedrich
Lüdeke and Daniel Wilckens at the Office of the Commissioners of
Patents, with their Petition, on the 26th October 1864.
We, JOHANN ERNST FRIEDRICH LÜDEKE, of 2, Stonefield Street, Islington, N.,
and DANIEL WILCKENS, of 25, Union Square, Great Dover Street, Borough;
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
MOTIVE POWER BY CAPILLARY ATTRACTION," to be as follows:-
We use two moveable steel plates, each has a moveable wire plate, both
connected with the fly wheel, which plates are so constructed that by moving
up and down capillary attraction and repulsion will be produced through
mercury or water, whereby a continual motion will be produced. We further
use two wheels whose edges touch each other, only one of them is surrounded
by sponge or carpet, and the other not, these two wheels are fixed in a vessel of
water, one-third of each is dipped in the water. This power is only produced
by attraction.

by the said Johann Ernst Friedrich Lüdeke and Daniel Wilckens in

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, JOHANN
ERNST FRIEDRICH LUDEKE, of 2, Stonefield Street Islington, and DANIEL
WILCKENS, of 25, Union Square, Great Dover Street Borough, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of October, in the year of our
Lord One thousand eight hundred and sixty-four, in the twenty-eighth year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
ns, the said Johann Ernst Friedrich Lüdeke and Daniel Wilckens, Her special
licence that we, the said Jobann Ernst Friedrich Lüdeke and Daniel Wilckens,
our executors, administrators, and assigns, or such others as we, the said
Johann Ernst Friedrich Lüdeke and Daniel Wilckens,
"
executors, admi-
nistrators, 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 MOTIVE POWER BY CAPILLARY ATTRACTION,"
upon the condition (amongst others) that we, the said Johann Ernst
Friedrich Lüdeke and Daniel Wilckens, 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 Inven-
tion, 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 Johann Ernst Friedrich Lüdeke and
Daniel Wilckens, 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 :-
Our Invention consists of improvements in motive power by capillary
attraction constructed in the manner herein-after described and illustrated in
the accompanying Drawings.
Figure 1 of the accompanying Drawings represents in horizontal section a
square case or cistern, this cistern is filled with water nearly to the top, and
two wheels marked a, a, and b, b, are placed in the water in the cistern. By
capillary attraction the water rises between the two wheels marked x, x, to a
height above the level of the water in proportion to the distance of the wheels

page_text: from each other at x, x. As the water rises between the wheels marked a, a,
above its level, the weight of water between the wheels at x, x, will cause
the wheels to continually revolve.
Figure 2 represents the same as Fig. 1, but in a vertical section. The said
power may be obtained by wheels moved on axis, or by other apparatus by
rise and fall in the water by vertical motion.
What we claim as our Invention is the new or improved motive power
herein described and illustrated in the accompanying Drawings, that is to
say, motive-power machine in which the motive-power is obtained by
capillary attraction by water or other liquids in the manner described and
represented.
In witness whereof, we, the said Johann Ernst Friedrich Lüdeke and
Daniel Wilckens, have hereunto set our hands and seal, this Twelfth
day of April, in the year of our Lord One thousand eight hundred and
sixty-five.
