I, JOHANN ERNST FRIEDRICH LUDEKE, of Dransfeld, in the Kingdom of
Prussia, at present residing at 281, New Cross Road, New Cross, do hereby
declare the nature of the said Invention for "IMPROVEMENTS IN APPARATUS
FOR OBTAINING MOTIVE POWER, AND FOR RAISING AND FORCING WATER AND FLUIDS,"
to be as follows:-
This Invention has for its object improvements in apparatus for obtaining
motive power and for raising and forcing water and fluids. I construct an
apparatus consisting of two cones, each mounted on an axis turning in suitable
bearings, and so arranged that the cones are in contact apex to apex and along
a straight line connecting the apex and base of each cone. These cones are
combined with a close casing in such manner that their bases form portions of
two opposite sides of the casing, and the interior of the casing is divided into
two chambers; the division on one side is formed by the line of contact between
the cones, and on the other by a plane surface or wing fixed to the side of one
of the cones in a radial position. The edge of this plane enters a groove cut
to receive it in the face of the other cone. The two chambers into which the
casing is thus divided are filled with water or liquid, and by suitable passages
put in communication with the two ends of a cylinder also filled with liquid
and having a piston-working-within-it; then if motion be imparted to the
axes of the cones first in one direction and then in the other, causing them to
rock through a small are, a movement will be imparted to the piston and

will continue for an indefinite time, and if the piston rod be suitably connected
with machinery it will drive it continuously. The result obtained is dependent
upon the pressure of the liquid on the two inclined surfaces of the cones
balancing each other, whilst there remains an outstanding unbalanced pressure
upon the radial wing or plane forming part of the partition between the
chambers.
A similar apparatus may be used as a pump, the cylinder and piston
being dispensed with, and the lower compartment of the casing connected with
the suction and the upper with the delivery pipe. A valve is fitted in the
delivery pipe, and another in the radial plane or wing. A plane surface and
a cone may be arranged to work in a similar manner in lieu of the two cones.
Also to be used as a pump I employ a somewhat modified arrangement.
Two discs are substituted for the cones; they are mounted on axes at an
angle so as to be in contact at one point in the periphery of each. One of
the discs carries a number of wings or planes upon it entering slots in the
face of the other. One dise only need be turned, and it drives the other.
The discs and wings then act to carry up water or liquid from the lower
compartment to the upper. The power necessary to be applied will only be
such as the friction of the parts absorbs.
