PROVISIONAL SPECIFICATION.
An Improved Elevator for Raising Fluids and Solids.
1, LEONIDE APOSTOLOFF, of 15 Rue des Halles, Paris, France, Doctor of Science,
do hereby declare the nature of this invention to be as follows:-
In an elevator according to this invention the substance to be raised, whether it be
fluid, liquid, or solid, is subject to the action of a vertical spiraloid to which is com-
municated a rapid rotary movement.
This spiraloid is arranged about a hollow vertical cylinder which serves as its support,
and it is surrounded by another hollow vertical cylinder which allows of its being
easily actuated. This outer cylinder also prevents the formation of eddies and currents
of air, and in consequence diminishes the friction in the air.
The spiraloid is partly immersed in the substance to be raised, particularly in the
case of a liquid; in this latter case it loses a portion of its weight and thus the friction
on the surfaces of support is proportionally reduced.
In one form of elevator according to this invention the spiraloid surrounds a hollow
cylinder, and its pitch diminishes towards its upper part.
This internal cylinder may be replaced by any solid of revolution, such as a
sphere, an ellipsoid, or a paraboloid, according to the requirements of the case.
This spiraloid is arranged vertically and is actuated in any suitable manner.
According to one method the motion is imparted to the apparatus by belts passing
round an enveloping cylinder which surrounds the spiraloid and serves as a driving
drum.
These belts pass over pulleys which carry friction discs in contact with a driving
disc or plate.
The spiraloid passes through the lower part of the envelope, and the substance to be
raised is introduced into the spiral through this opening.
By reason of the speed of the apparatus, this substance rises to the upper part of the
spiral which again passes through the enveloping cylinder, and discharges it into an
annular reservoir whence it is conveyed to the point where it is to be utilized. The
spiraloid may be driven in many different ways, for instance the motor may be a
dynamo arranged vertically and placed inside the internal cylinder.
The spiraloid is attached to this cylinder and is surrounded as already described by
another enveloping cylinder connected to the first one by a frame carrying rollers to
support the apparatus and rolling on a path.
The central dynamo is fixed and the motion is transmitted to the apparatus by
an arrangement of gearing which operates a crown wheel fixed on the enveloping
cylinder.
In order to guide the apparatus in its rotary movement, horizontal rollers are
arranged around it and roll on the surface of the enveloping cylinder.

An Improved Elevator for Raising Fluids and Solids.
I, LEONIDE APOSTOLOFF of 15 Rue des Halles, Paris, France, Doctor of Science,
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:
In an elevator according to this invention the substance to be raised, whether it be
fluid, liquid, or solid, is subject to the action of a vertical spiraloid to which a rapid
rotary movement is communicated. Apparatus according to this invention can be put
to various uses such for example as in borings, soundings, and for producing
waterfalls.
The spiraloid is arranged about a hollow vertical cylinder which serves as its support
and it is surrounded by another hollow vertical cylinder which allows of its being
easily actuated. This outer cylinder also prevents the formation of eddies and current
of air, and in consequence diminishes the friction in the air.
The spiraloid is partly immersed in the substance to be raised, particularly in the
case of a liquid; in this latter case, it loses a portion of its weight and thus the
friction on the surfaces of support is proportionately reduced. The apparatus is illus-
trated in the annexed drawings of which
Fig. 1 is an elevation with the outer cylinder removed and
Fig. 2 is a longitudinal section.
A is the hollow cylinder, B the spiraloid, whose pitch diminishes towards its upper
part. The cylinder A may be replaced by any solid of revolution, such as a sphere,
an ellipsoid, or a paraboloid, according to the requirements of the case.
This spiraloid is arranged vertically and is actuated in any suitable manner.
Fig. 3 illustrates one of these arrangements in which the motion is imparted to the
apparatus by belts passing round an enveloping cylinder which surrounds the spiraloid
and serves as a driving drum. These belts pass over pulleys M and N¹ which carry
friction discs N and Ni in contact with a driving disc or plate P.
The spiraloid passes at D through the lower part of the cylinder C, and the substance
to be raised is introduced into the spiral through this opening. By reason of the
speed given to the apparatus, this substance rises to the upper part of the spiral which
at E again passes through the enveloping cylinder, and is discharged into an annular
reservoir F whence it can be conveyed to the point where it is to be utilized.
The spiraloid may be driven in many different ways, for instance, as shewn in Fig. 4,
the motor may be a dynamo K arranged vertically and placed inside the internal
cylinder A. The spiraloid B is attached to this cylinder and as already described is
surrounded by another enveloping cylinder C connected to the first one by a frame G
carrying rollers H to support the apparatus and rolling on a suitable path. The
dynamo K is fixed and the motion is transmitted to the apparatus by an arrangement
of gearing which operates a toothed wheel L. fixed on the cylinder C.
In order to guide the apparatus in its rotary movement, horizontal rollers S are
arranged around it and roll on the surface of the cylinder (.
Having now particularly described and ascertained the uature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
An elevator for raising fluids and solids comprising a hollow vertical spiraloid B
whose lower end is designed to be immersed in the substance to be raised and to which
rapid rotary motion can be imparted, substantially as shewn in and described with
reference to the drawings annexed.
