COMPLETE SPECIFICATION.
Improvements relating to Turbines,
1, CARL WEICHELT, of Kriwokolenni, Pereulok, Moscow, Russia, Manufacturer,
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 follow-
ing statement:-.
The hitherto known turbines have the disadvantage of great circumferential
rapidity of the turbine wheel and consequently danger of bursting from a strain
which is too great for the material and moreover they lose in efficiency in con-
sequence of the excessive exit rapidity of the steam or gas from the turbine wheel.
The present invention is designed to do away with these disadvantages by the use
of several couples of guide and turbine wheels lying close together and all the
turbine wheels being fixed on a common axle and all the guide wheels joined
with the turbine casing.
In the annexed drawing Fig. 1 is a vertical section of the improved turbine.
Fig. 2 is a sectional view of the same taken on a curved plane passing through
the steam passage ways.
The action of this turbine is as follows:-The steam or gas escaping from the
first guide wheel (Figs. 1 & 2) provided with a regulating device goes into the
first turbine wheel and gives to it as well as to the others 62 63 because they are
fixed on the same axle the desired circumferential rapidity. The other
guides and a act in a similar way. The steam or gas now runs with
diminshed rapidity through the channels of the turbine wheel and quits the same
with again diminished rapidity.
With this rapidity the steam or gas runs then through the second guide wheel a
serving to give it the necessary direction for entering the second turbine wheel b²;
in the same manner all the guide wheels serve to give the steam or gas the required
direction for its entrance into the next following turbine wheel.
In going through the channels of the second turbine wheel and in going out of
the same and also of all the following the rapidity of the steam or gas diminishes
in a similar manner as in running through the first turbine wheel till it is reduced
in coming out of the last turbine wheel to nearly the circumferential rapidity of
the turbine wheels. The number of couples of guides and turbine wheels can be
easily found the tension of the steam or gas and the number of revolutions of the
turbine wheel having been fixed.
The advantages of the new connected turbine consist in obtaining a useful
number of revolutions of the turbine axle without the use of gear in diminishing
the danger of a bursting of the turbine wheels and in obtaining a greater
efficiency in consequence of better utilization of the steam or gas.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed I declare that what I claim is;.

In a steam or gas turbine the combination with a casing and an axle of a

being connected with the turbine casing and the turbine wheels fastened on the
axle and having these steam passages in the same curved plane of rotation
substantially as set forth.
