I, FRITZ EISENBEIS of Wellesweiler near Trèves, Germany, Blacksmith, 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 :-
The improved turbine is represented in the annexed drawing by Fig. 1 in a vertical
section with a part front view, by Fig. 2 in a transversal section whereas Figs. 3 to 8
show the details.
The turbine wheel A is placed in a casing B similar to ventilating constructions
with a widened diffusion chamber around the wheel and in the peripherical side of
this casing B' is fixed in one or several places in flanged pipes D, the water-feeding
apparatus C.
In the periphery of the turbine wheel A are the floats S uniformly distributed &
which are represented on a larger scale in Figs. 4 to 8. These are composed of a
metallic basin a in the form of a float with a ledge at its forepart and sides slightly
deviating upwards, a side c sloping backward, a raising d with its forepart bevelled,
in the middle, and different ribs e made in their periphery in the form of a knife
parallel with each other and perpendicular to the bottom of A at the foremost edge of
the floats and which, at this point traverse the floats in such a way that each part e
of the side both on the inside and outside of the float, projects and a series of parallel
ribs is formed on the inside and outside. On this float are also at its back part, two
identical and parallel clutches f which are sufficiently long to admit of two screws or
rivets being placed in them by means of which these clutches and the floats are fixed
to the disk of the wheel A, the latter being then seized by the two clutches f and to
some extent by the back edge c which is grooved for this purpose at its middle part g
and penetrating into the interior of the float.
On the lower surface of the float is again made a bead in the form of a heel
leaning against the periphery of the wheel A and when the water falls, serves as a
support to the float.
The floats are fixed in such a way that the clutches f are arranged radially and the
back side c conform with the periphery of the wheel A, the float itself being
consequently directed a little obliquely with the edge of the wheel but in such a way
that its front edge b is parallel with the radius of A passing by the corresponding
clutches f and receives a perpendicular water fall directed in a tangent with the
periphery of the wheel.
The organ of admission of water C is in a tube D at the periphery of the casing B.
It has the form of a cylinder terminating in a cone at its lower end and which,
excepting a narrow passage in the form of a crescent k, is closed by a small cross-piece i.
The side is lengthened downwards beyond i and is then cut obliquely in such a way
that the water which escapes from k is limited and guided by the part of the side
opposite to the exterior of the turbine wheel A, whilst on the side turned towards the
floats and the wheel, there is a spacious escape to the water.
This organ C for the admission of water is supported in the tube D by a piece E
bolted upon D by means of the flanges t, u¹, and whose lateral tube m ends in the
conduit pipe, whilst the upper tube n is closed by a cover F with a stuffing-box o and
a screw trestle p.

page_text: Through this trestle p and the stuffing-box o passes the rod p of a valve r which is
seated at the bottom at the narrowest extremity of the body C. The valve spindle q
and the valve r are worked by the hand-wheel H.
The water which penetrates into m consequently flows through C downwards and
slightly decreasing the section finally flows forcibly through the opening k which is
profiled in the form of a crescent from where it flows flat, preserving the form of an
arc and arrives on the foremost edge 6 of the floats.
The distinguishing feature here is the flat flow of water in the form of an are which
corresponds in form and dimension with the bent fore-edge of the float and which
falls perpendicularly upon this and therefore acts upon a sufficiently extended surface
of the float in an absolutely perpendicular direction to it so that the float is thus
violently driven from the opening of the body C by which the paddle wheel A is put
into motion, the float immediately following being thus brought before the mouth of
the body and so on.
The blades e serve to moderate more or less, the force of the water-fall, more
especially to divide this volume of water, which forms a crescent surface, into several
belts to prevent its spurting out.
The narrower the point of the body C and the nearer it is to the fore-edge b of the
floats the better is the action of the water fall and the more completely is the water
utilized.
Instead of a single tube D, with the admission pipe C we might evidently, as
shown by dotted lines in the design add one or more D¹ C¹ & D2 C2 so that the force
of the water may be exercised upon the wheel from different places and by different
floats.
Instead of providing, as shown by Fig. 1, the water pipe C with a small projecting
edge s and pressing it thus between the collars tu¹ of the tube D respectively of the
part E we might naturally make C & E in one piece so that C would be simply passed
through D and the collars u¹t would be bolted upon each other.
The water falling upon the floats S and divided into several belts by the blades e is
driven by the sloping middle piece d towards two lateral recesses v, w so that the
next arrival of water again strikes against the fore-edge of the float which is supplied
with blades, whilst the water used flows into the diffusion chamber and spreads out
with the rotation and escapes by O.
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 distinguished by the arrangement of the section in a crescent form of
the mouth of the water admission pipe to give the water-spout a large extent
in the form of an arc, and by the arrangement of blades on the fore-edge of the floats
fixed to the periphery of the wheel to divide thus the water which leaves in a wide
and flat stream, into different vertical belts to avoid the rebounding of the water as
much as possible and to ensure the greatest effective force of the water upon a larger
surface of the float.
2. An improved turbine substantially as described and shown.
