Improvements in or relating to Turbines.
We, ANTOINE JOURDANET and JULES PROSPER GAUTHIER, both of 34, Rue
Ferrandière, Lyons, in the Republic of France, Engineers, do hereby declare the
nature of this invention to be as follows:-
This invention relates to a new auto-rotary turbine carrying its directing boxes,
and worked by the continuous introduction by means of the rotary axle of the
steam or other fluid under pressure, which hereinafter referred to as the moving
agent, which by escaping by or through the directing boxes provided on the said
turbine gives the latter a rotary movement transforming into mechanical energy the
expansive force of the moving agent used.
The turbine is formed of the following pieces.
A disk carrying the directing boxes tangent to the inner wall, a hollow shaft
screw threaded on said disk serving as axle to the turbine in one direction and also
serving for introducing into the turbine the steam or other moving agent and
a solid shaft extending in the other direction carrying at one extremity a conical
tight disk forming part of the turbine and carrying at the other extremity a driving
pinion.
The receiving paddle carrier is formed by the following pieces.
A disk carrying the paddles on which the moving agent strikes as it leaves the
turbine, a hollow screw threaded axle fixed to the disk carrying at its end a pinion.
This disposition allows of fixing the paddle carrier or of letting it turn by utilizing
the force which it can produce without hindering the play of the axle of the turbine.
A steam tight joint at the end of the hollow turbine, axle allows of introducing the
steam or other fluid while the axle is in motion.
A close casing surrounds the turbine and the paddle.carrier.
In order to allow of the expansion of the moving agent we provide at the periphery
of the turbine directing devices tangential to the inner wall; the moving agent
leaving these directing boxes, meets a series of paddles which one can turn on their
axle, or can be fixed: the turbine keyed on a movable axle receives a reacting
impulsion in a reverse direction to the directing boxes, and turns with a rotary
movement, the value of which is determined by the pressure of the driving agent
used.
We can also let the paddles turn which will be moved with a reversed movement
to that of the turbine and can utilize these two forces by coupling them on a
secondary axle which could then serve for transmitting the energy produced.
This latter combination is intended to utilize in a more rational manner the
expansive force of the moving.agent by doubling the normal utilisation of its initial
velocity.

We, ANTOINE JOURDANET and JULES PROSPER GAUTHIER, both of 34, Rue
Ferrandiere, Lyons, in the Republic of France, Engineers, 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 relates to a new autorotary turbine in which the interior member,
containing a chamber having in its periphery a comparatively few directing boxes
with tangential passages, lies within the exterior member having in its periphery a
comparatively large number of passage ways curved from a direction approximately
tangential in the inside to a position approximately radial on the outside. The
steam or other motive fluid supplied to the interior of the inner member escapes
from the openings in the periphery thereof and entering the passages in the outer
member strikes on the walls thereof tending to give a rotary motion either directly
to the outer member, or reactively to the inner member or to both members, while
finally escaping on the outside of the outer member in such a way as not to form a
drag on the rotation of either member.
In the annexed drawings Fig. 1 is a longitudinal section on line 1-1 of Fig. 3.
Fig. 2 is an end view. Fig. 3 is a plan of the turbine, and Fig. 4 is a section through
the chamber of the turbine.
The turbine A is formed of the following pieces.
A disk a¹ carrying the directing boxes M tangent to the inner wall, a hollow
shaft a² screw threaded to said disk a¹ serving as axle to the turbine A in one
direction and also serving for introducing into the turbine A the steam or other
moving agent and a solid shaft a extending in the other direction carrying at one
extremity a conical tight disk as forming part of the turbine and carrying at the
other extremity a driving pinion D.
The receiving paddle carrier is formed by the following pieces.
A disk b carrying the paddles 62 on which the moving agent strikes as it leaves
the turbine A. A hollow screw threaded axle 63 fixed to the disk b¹ carrying at its
end a pinion E. This disposition allows of fixing the paddle carrier B or of letting
it turn while utilizing the force which it can produce without hindering the play of
the axle a of the turbine A. A steam tight joint C at the end of the hollow
turbine axle allows of introducing the steam or other fluid while the axle is in
motion.
E is the pinion fixed on the shaft B of the paddle disk 61. When this disk is to
turn the intermediary spur wheel N is slid laterally along its shaft n until it gears
with pinion E and also with wheel G on the shaft J. On the latter shaft are the
pulley I and the spur wheel F engaging with the pinion D on the turbine shaft a².
By this means the revolutions of the turbine and the paddle disk in contrary
directions are both utilized to revolve the shaft J continuously in one direction.
H are the bearings for shaft J.
A close casing K surrounds the turbine and the paddle carrier.
In order to allow of the expansion of the moving agent the directing devices M
at the periphery of the turbine form slots tangential to the inner wall, the moving
agent leaving these slots, meets a series of paddles which can turn with their axle,
or can be fixed; the turbine on its rotary axle receives a reacting impulse in a
reverse direction to the paddles, and turns with a rotary movement, the value of
which is determined by the pressure of the driving agent used.
We can also let the paddles turn which will be moved with a reverse movement
to that of the turbine and can utilize these two forces by coupling them on a
secondary axle which could then serve for transmitting the energy produced. This

page_text: latter combination is intended to utilize in a more rational manner the expansive
force of the moving agent by doubling the normal utilization of its initial
velocity.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed we declare that what
we claim is :-
1. In a rotary turbine the combination with a pair of disks forming a chamber
with directing boxes M forming slots tangential to the periphery of said chamber, of
a hollow shaft extending axially from said chamber in the one direction means for
introducing motive fluid into said shaft, a shaft extending from said chamber in the
other direction, a sleeve surrounding the latter shaft, a disk on said sleeve a
peripheral outer member on said disk in the plane of the aforesaid directing boxes
and having through it a plurality of passage ways approximately tangential at their
inward entrance and approximately radial at their outward outlets adapted to permit
of the passage of the exhaust of the motive fluid on the outside of said outer
peripheral member, substantially as and for the purpose set forth.
2. The combination in a turbine of the disks a 2 and boxes M forming a chamber
with tangential outlets, hollow shaft A means for introducing motive fluid thereto,
shaft sleeve B disc b¹ thereon, paddles 62 on said disk b¹, pinion D on shaft at
pinion E on sleeve B gear wheels F and G and interally displaceable gear wheel N,
the whole substantially as and for the purpose set forth.
Dated this on day or August 1890.
