Improved Weight or Buoyancy Motor.
I, WILHELM MARTIN CABJOLSKY, of 11, Mittlerer Fontainenweg, Odessa, Russia,
Architect, 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:—
My invention relates to an improved power engine.
If a horizontally supported cylinder be held in bearings at the end points of its
axis it is in a position of stable equilibrium, because its centre of gravity coincides
with the axial line. But if this cylinder consist of two halves the plane
of separation of which coincides with a vertical plane on the axial
line, then each half of the cylinder will have a special centre of gravity. As both
halves consist of the same material these centres of gravity must lie equi-distant
from the central plane, and the same forces must act on both. The connecting line
between the two centres of gravity can therefore be regarded as a double armed
lever of equal arm lengths, the turning point whereof lies in the axial line.
If as above stated equal forces are in action the whole is in equilibrium. If the
action of gravity in the one or the other half of the cylinder be wholly or partially
neutralized, the balance of the cylinder is destroyed. Consequently it will seek to
restore the equilibrium, that is to say, it will commence to rotate. The like action
occurs when the two cylinder halves are made unequal, and the action of gravity
altered with respect to one half. Only the product of the gravity acting in the
cylinder half which has remained unaltered, multiplied by the distance of its centre
of gravity from the axis of revolution of the cylinder must be greater than the
product of the gravity of the other half cylinder multiplied by the distance from its
centre of gravity.
Any rotary body will act in like manner as the cylinder, if it is freely supported
upon its axis of rotation.
The action of my power engine depends upon the above considerations.
My invention is illustrated in the accompanying drawing in
Figure 1 in front elevation, in
Figure 2 in side elevation, and in
Figure 3 as seen from above.
A cylinder A (or a ball or the like) rests with its axle revoluble in bearings B which
are preferably ball bearings to reduce the friction. In order to alter the balance of the
cylinder it is caused to plunge up to nearly half its diameter in a fluid C. Water is prob-
ably the cheapest and most convenient medium. The weight of the immersed portion
of the cylinder will be diminished by the amount of the weight of the displaced fluid.
It is therefore clear that the reduction in weight will be greater according as the weight
of the fluid employed is increased. If the upper or the lower half of the cylinder
were treated in this manner there would be no revolution because in the one case
stable equilibrium is obtained, that is to say, the centre of gravity of the whole
system would lie under the supporting axis, and in the other case the centre of gravity
would lie over the supporting axis, but so that the direction of the gravity would pass
through the same giving consequently unstable equilibrium. The equilibrium could

turning of the axle. But if the one half of the cylinder pass sideways through the
exactly cut out wall of a reservoir D and be plunged in water, then the conditions
are such that through the alteration in weight a rotation will be caused. As,
however, in each following position the balance is again destroyed the rotation will
follow continuously.
In order to prevent as far as possible the escape of water from the reservoir the
edges of the same are provided with waterproof linings which apply themselves against
the surface of the cylinder.
In practical construction it is advisable not to allow the full half of the
cylinder to be immersed, but to allow the axis to remain a little to one side.
In most cases the cylinder periphery will be wetted by the fluid; there will

preferable to give the front wall of the reservoir the curved shape shewn in
Figure 2, which projects above and below up to or over the highest and lowest
point.
In order to replace the inevitable losses of fluid a special water supply must be
provided. The machine will work so much the better according as the difference in
weight of the two half cylinders is greater, and according as the aperture cut in the
reservoir wall is smaller in relation to the turning power. The diameter of the
cylinder should in no case be made smaller than one and a half meters otherwise
the frictional resistance becomes too great in proportion to the power of revolution.
The size of the cylinder is practically unlimited so far as it is possible in industry
to construct cylinders and axles.
Thus power may be produced in this manner which can amount to many thousand
horse power.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
The power engine consisting of a cylinder or the like revoluble on a horizontal
axle, and having approximately half the cylinder penetrating sideways through the
wall of a reservoir of fluid, the sides of the aperture being well sealed in order to
prevent as far as possible loss of fluid, whereby through the said immersion the
balance of the cylinder is altered in such a manner that a continuous rotation results
substantially as described.
