COMPLETE SPECIFICATION.
An Improved Turbine.
I, HUGO WENTZKY, of 71, Königgratzer Strasse, Berlin, in the German Empire,
Merchant, 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, reference being had to the accompanying drawings and to
the letters and figures marked thereon, that is to say :-
This invention relates to an improved turbine, and will be readily understood on
reference to the annexed drawings, in which:
Fig. 1 is a longitudinal section through the box and the two nozzles.
Fig. 2 a transverse section, and
Fig. 3 a side view.
In its essential parts, this turbine consists: --Of the box A, provided with a
segmental piece, and connecting tubes and d' in which are fitted the nozzles; of
the cover B; of the bucket or float-wheel C; of the feed nozzles D and E; and of the
outlet channels F and G partially connected together.
The new turbine is characterized by the arrangement of its feed nozzles at a right
angle, and by the partial communication of its outlet channels, and the advantage of
these arrangements is that a very small quantity of water is sufficient to obtain a
sufficiently large force. The two orifices d'and e have, in the example shown in the
drawings, a diameter of 0.9 m/m, the delivery of water being 3 litres per minute, and
the number of revolutions 1800.
The arrangement of the two feed nozzles is the following:-As shown in Fig. 1,
the longitudinal median line of the nozzle D strikes the point of the third bucket or
float (counting from the top) of the float wheel C, whilst the fourth float is struck in
its middle. The longitudinal line of the nozzle E strikes the eighth bucket or float
at ths of its total length, and the ninth at ths of its total length. Hence it follows
that one of the buckets or floats of the wheel is always under the influence of the jet,
and is struck by it about its middle so that the turbine can be started at any moment.
The outlet space F is separated from the feed nozzle E, so as to prevent the water
on leaving the third bucket or float meeting the water from the terminal orifice e of the
nozzle, as this would contribute to render the current of water irregular at its outlet.
To this end, the segmental piece f, traverses the whole width of the box (see Fig. 1) and
is connected to the wall of the box by means of the tube into which is fitted the
feed nozzle E.
The water on leaving the outlet space F, is forced to pass on both sides of the
tube'. Care must be taken at the same time that the water only remains stationary
a short time in the buckets or floats, in proximity to the feed nozzles, as otherwise too
great friction would be set up and hence there would he a loss of force. To avoid this
loss, it is important that each bucket or float, filled with water and closed on all sides,
and not communicating with the next bucket or float, should travel a distance equal
to rd of its own length so as to empty itself suddenly.
H is a box which serves to collect a small quantity of the water coming from the
turbine, so that it may be used for any other object.
To prevent too much water being stored up, the lateral walls of the box H are
provided with oblong openings h, whilst its lower end is provided with small
tubes h¹, h², h³, h', to which may be attached bottles to be filled with a suitable
quantity of water.

page_text: 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
1. A turbine having its feed nozzles separated from each other and arranged at
about a right angle, so that the first nozzle opens on to the third bucket or float, and
the second on to the eighth bucket or float, substantially as described.
2. The combination with a turbine, such as characterized in Claim 1, of two distinct
outlet channels for the purpose of effecting the discharge of the first bucket or float
before the filling of the second by the second feed nozzle, substantially as described.
3. The combination with the turbine characterized in Claims 1 and 2, of a water
box H having its lateral walls provided with oblong openings h and its lower extremity
with four outlet tubes h', h2, h3, h4, substantially as described.
4. My improved turbine substantially as described and shown with reference to the
accompanying drawings.
Dated this 17th day of January 1896.
