PROVISIONAL SPECIFICATION.
Improvements in Air Turbines.
I, LOUIS ETIENNE ROZE, of Beziers, in the Republic of France, Traveller, do
hereby declare the nature of this invention to be as follows:-
This invention relates to improvements in air turbines and consists of two
circular plates in shape conforming with that of the wheel. These plates, at their
circumferences are hermetically bolted together, so us to form an air tight
interior, in which is employed the wheel consisting of a cylindrical disc with
rotary projections or furnished with soft sliding leather pieces, fitting air tight
between the said plates.
Air pockets or reservoirs are provided in the casing to maintain a constant
pressure on each rotary projection at the time of its passage. The shaft of the
turbine actuates on one side a driving gear and on the other a force and suction
pump, which draws the air from the turbine and compresses it into accumulators.
The air turbine described may be arranged in a compound manner, one of the
same actuating an air compressing pump drawing air from the exterior to
compensate for the loss and maintain between all the parts a continuous pressure,
which may be increased or diminished at will by closing or opening the air outlet.
The accumulators at first are charged by an air compressing pump and once
under pressure they cause the wheel to rotate, the pressure renewing itself by the
movement of the pumps actuated by the turbines.
The flat surface of the plates of the turbine on the inner sides are furnished
with polished glass to diminish friction and wear.
The employment of this turbine is universal where a motor is required.

1 LOUIS ETIENNE ROZE, of Beziers, in the Republic of France, Traveller 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:-
This invention consists of an improved turbine to be operated by compressed air
and continuous pressure and is illustrated by the annexed drawing in which :-
Fig. 1 represents a plan view of a system of turbines. Fig. 2 an elevational
view thereof.
Fig. 3 sectional plan view of the turbine.
Fig. 4 vertical sectional view through the turbine.
This new air turbine consists of two circular plates I having each the form of
a shield. These plates are united at their peripheries by means of bolts thus
providing an hermetical closure, leaving an empty inner space which contains a
rotating plate C; the enlarged periphery of this plate is provided with notches
furnished with pieces of leather sliding smoothly over the walls of the discs I and
thus producing an hermetic closing between each portion.

page_text: Wind pockets or reservoirs B are arranged in the outer portions of the discs I
serving to maintain a constant pressure on each circular notch of the turbine at
the moment of its passage.
The arbor of the turbine actuates at the one side the motor gear N and N' and
at the other a force and suction pump E which, when the turbine is driven by
force, sucks the air from the turbine and forces the same into the accumulators L,
operated by the eccentric G. The arrangement shown in Figs. 3 and 4 is of
quadruple expansion, one of the turbines actuating a compressed air pump E¹
taking the air from outside for compensating the escape and maintaining an equal
pressure between all parts. This pressure may be increased or diminished at will
by closing or opening the air escape.
The accumulators L are at first set under pressure by the aid of a compressed
air pump El and once under pressure they can be used to drive the turbines, the
pressure being renewed when desired by the movement of the pumps actuated by
the turbines.
The level portion of the turbines is provided at each side with a circular plate
of polished glass to diminish the friction and likewise wear and tear.
This improved disc shaped air turbine may be devoted to various uses as a
motor.
In the drawing, A is the pipe for admission of compressed air originating from
the accumulator; B expansion chamber; C turbine; D pipe for the escape to
the pump; E pump for sucking the air from the turbines and for forcing the same
into the accumulators-F the escape valve into the accumulator; G eccentric
actuating the pump; H escape valve for starting or setting in motion; I turbine
case; K tightening list; L accumulators; M, port for the first charging with
compressed air of the accumulators. N pinion actuating the arbors of the three
elevating propellers described in the Specification of my Patent No. 7751 of 1893;
O, pulleys actuated by the pinion N; P air valve for the turbine operating the
shaft with the two propellers described in the said Patent.
of this
Having now particularly described and ascertained the nature
invention and in what manner the same is to be performed, I declare that what I
claim is―
1. An improved disc shaped air turbine consisting of two plates I between
which a circular plate C moves, this circular plate being provided with notches,
the latter mounted with leather blades, assuring tightness between each portion;
said two plates which form the shield being united by bolts and carrying between
themselves and the notched plate two discs of polished glass for decreasing the
friction and wear and tear.
2. The combination with said air turbine of a suction and force pump taking the
the air from the turbine or from outside and forcing it into the accumulators L.
Dated this 17th day of January 1894.
