New or Improved Method of and Means for Utilizing the Centrifugal
or Projecting Force of a Rotary Body.
We, CYRIN VAN DER ELST, Engineer, and BERNARD LOEWENSTEIN, Banker,.
both of Rue Neuve 17, Brussels, in the Kingdom of Belgium, do hereby
declare the nature of this invention and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement
The object of the present invention is to utilize not only the vis viva or living
force of a rotary body, but also its centrifugal force engendered at the same time.
To obtain this result, it is necessary that the active body should be sufficiently
heavy and liquid, as for instance water, and that the device employed for imparting
rotary motion to the same should be so constructed and arranged as to create a
continuous stream from the centre towards the periphery, where the liquid is
projected against paddles or buckets and returned to its point of departure without
a sensible effort in order to be projected again.
The paddles must be necessarily arranged above the surface of the liquid and
may form part of a special paddle wheel or be fixed to the rotary device. In this
case the rotation of the latter will be accelerated and its mis viva increased by the
centrifugal force of the water.
The apparatus which fulfils these conditions is represented in the annexed
drawings in which Fig. 1 is partly a side view and partly a section through
line XY of Fig. 2, whereas the latter is a horizontal section through the com-
partment g of Fig. 1.

The apparatus consists of a fixed tank a filled up to about with water and
traversed in its middle by a vertical axle tree b, which is put in motion at the out-
side by means of the crank c or by any other suitable arrangement.
To said axle tree is fixed, so as to be partly immersed in the fluid, the afore-
said rotary device, consisting of a bell shaped vessel d, or of any other suitable
shape, which is closed at its upper part and provided at the under side with a central
sucking opening or tube e.
The inner space of the rotary bell d is divided by conical walls into three
compartments f, g, h, of which the middle one g only communicates with the central
sucking opening e, whereas f and are empty spaces for the sole purpose of
diminishing the weight of the rotary bell and consequently its pressure upon the
axle tree . These two compartments fand may be suppressed if desired as not
constituting an essential feature of the apparatus.
The middle compartment is subdivided by vertical partitions into several
channels i, Fig. 2, which diverge and lead from the sucking opening e to the
periphery, for the purpose of conducting the water to outlet openings k. In front
of the latter are secured to the bell shaped vessel d the inclined paddles for the
purpose of receiving the water jet. mm are guide plates or boards intended to
avoid fluctuations of the water in the channels i if required.
The number of outlets and paddles may be varied at will, and thereupon depends
the arrangement of the channels i which may be straight or curved in the direction
of rotation.

The axle tree bis supported in the bearing o by friction rollers n n
same may also run in a step bearing fixed in the tank a and provided with friction
balls of steel or other metal if desired.
The action of the apparatus is as follows:-
The bell shaped vessel d being put in motion, the water contained in the same
is driven forwards in the channels i by virtue of the centrifucal force develoned.

accelerate the motion of the bell shaped vessel d. The liquid then falls back
into the tank and is sucked up again by the bell at the central opening e, by virtue
of the vacuum which the centrifugal force tends to create in the interior of the
bell. The motion of the water is indicated in the drawing by arrows.
The apparatus may be applied to all types of steam, gas and hydraulic engines
as well as to pumps, it being employed instead of a fly wheel, or used in the manner
described by mounting it upon a vertical shaft.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The mode or method of utilizing the centrifugal or projecting force of a
rotary body, by employing as a body a liquid contained in a tank and being con-
stantly sucked up and projected against inclined paddles by a suitable rotary
device to which said paddles are secured above the level of the liquid; the
liquid jet after having produced its effect falling back into the tank and being
sucked up again.
2. The apparatus constructed accordingly, consisting of a fixed tank a provided
with a vertical axle which is put in motion by any suitable arrangement, in
combination with a revolving vessel d so fixed to said axle bas to be immersed
partly in the liquid, and provided with a central sucking opening e, projecting
channels i, outlets k, and paddles I, situate above the level of the liquid, all sub-
stantially as and for the purpose described and represented.
