PROVISIONAL SPECIFICATION.
Improvements in and relating to Water Wheels.
I, ERNEST BROOK TAYLOR, of 7A, Mosley Street, Manchester, in the County
of Lancaster, Cycle Agent, do hereby declare the nature of this invention
to be as follows:-
This invention relates to water wheels of the Pelton or impact type and its
object is to so construct them as to improve their efficiency.
In the improved wheel the blades or vanes are so arranged that they come
obliquely across the jet of water. They are also so placed that the water may
pass them and exert its force upon the preceding vanes, so that instead of only
one vane or blade being actively operated at a time as in the ordinary Pelton
wheel, two or more blades are acted upon by the water together.
In one form of wheel the vanes are arranged in an inclined position between
flanges, the rear or following end of each blade being further from the centre
of the wheel than the leading end, enough space being left between the latter
end and the substance of the wheel to allow of the passage of all or some of
the water. The water jet is directed against the under side of the vanes so
that it drives the wheel forward and at the same time passes the vane against
which it has impinged and acts upon the preceding vane or upon several pre-
ceding vanes.
In another form the vanes are arranged vertically but obliquely across the
wheel. The water in this case impinges against the side of a vane and forces
it forward at the same time passing along it until it comes against the rear
end of the next preceding vane which is placed in the opposite direction, upon
the wheel to the first vane. It may then pass along the second vane to the
third and from the third to the fourth and so on if desired, exerting an influ-
ence upon each. These vertical vanes may, if desired, be provided with flanges
at their upper edges, and these flanges may also be further from the centre of
the wheel at their following ends than at their leading ends. Each of these
vanes is arranged in an opposite direction across the wheel to the adjacent
vanes.

Improvements in and relating to Water Wheels.
I, ERNEST BROOK TAYLOR, of 7A, Mosley Street, Manchester, in the County
of Lancaster, Cycle Agent, 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 water wheels of the Pelton or impact type and its
main object is to so construct such wheels as to improve their efficiency.

page_text: In the improved wheel the vanes or blades are so arranged that they come
obliquely across the jet of water, and each one is of such dimensions or is so
placed that, when subjected to the direct action of the jet, the water may pass
it and exert force upon the next preceding vane or upon a preceding vane or
vanes, so that instead of only one vane or blade being actively operated at a
time as in the ordinary Pelton wheel, two or more blades are acted upon by
the water together from the same jet.
The appended drawings illustrate two forms of wheels constructed to embody
these improvements.
Figure 1 is a diagrammatic side elevation of one form of wheel.
Figure 2 is a diagrammatic edge elevation of part of another form of wheel.
Figure 3 illustrates in side elevation and cross section a form of vane or
blade which may be used with the wheel shown in Figure 2.
The wheel represented in Figure. 1 consists, as is usual, of a number of spokes
or arms A radiating from a hub B to a periphery or rim C which may be open
or solid. Attached to the rim are flanges D, (one only is shown,) between
which are placed the vanes or blades E. As illustrated these vanes are placed
obliquely to the jet of water from the nozzle F and are so arranged and are of
such dimensions that the lower edge of each vane is capable of permitting the
passage of water from it to the next preceding vane. Thus, water which
strikes the vane 1 may pass along it and be delivered to vane 2 which, in this
manner, is acted upon in addition to vane 1. In some cases the water may pass
to vane 3 and to still further preceding vanes and exert force upon them all
simultaneously.
The water jet is thus directed against the under side of a vane so that it
drives the wheel forward and at the same time passes the vane against which
it has impinged and acts upon the preceding vane or several preceding vanes.
In some cases, dependent upon the form, dimensions, or inclination of the
vanes, the water after impinging upon a vane may pass the next preceding vane.
and be delivered to the vane in front of it.
In another form of wheel which is illustrated in Figure 2 the vanes E are
arranged obliquely across the wheel, and are contained as before between the
flanges D. The water in this case impinges against the side of a vane 1 and
forces it and the wheel forward. At the same time the water passes along the
vane until it comes against the rear end of the next preceding vane 2 which is
placed in the opposite direction upon the wheel to the first vane. If the water
possesses sufficient energy it may pass along the second vane to the next vane 3
which is placed in the same direction as the first, and so on around or partly
around the wheel. The vanes are alternately placed in opposite directions with
sufficient space left at their leading ends for the passage of water.
If desired the vanes in this second type of wheel may be provided with flanges
such as G at their upper edges projecting over the face against which the water
impinges as shown in the Figure 3 where a vane E is illustrated in side eleva-
tion and in cross section. Such flanges may be further away from the centre
of the wheel at the rear ends of the vanes than at their leading ends.
It will be obvious that the vanes may be arranged differently to those
illustrated and yet attain the same result of allowing water which has impinged
against one vane to pass along such vane and be delivered to the next preceding
vane or to a preceding vane or vanes to exert pressure upon it.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what
I claim is:-
-
1. An impact water wheel the vanes or blades of which are arranged obliquely
to the line of the jet of water in such a manner that the water may pass from
a vane upon which it has already impinged to the next preceding vane or to a
preceding vane or vanes, constructed and arranged substantially as and for the
purpose herein before described and as illustrated by the accompanying drawings.

page_text: 2. An impact water wheel the vanes of which are arranged at right angles
to the plane of the wheel and obliquely so that water may pass from one vane
to the next preceding vane or to a preceding vane or vanes, substantially as
described and as illustrated by Figure 1 of the accompanying drawings.
3. An impact water wheel the vanes of which are arranged upon the wheel
alternately in opposite directions and obliquely to the line of the jet of water
so that water may pass from one vane to the next preceding vane, constructed
and arranged substantially as herein before described and as illustrated by
Figure 2 of the accompanying drawings.
4. A vane for an impact water wheel which is arranged obliquely to the
line of the jet of water and is flanged upon its upper edge substantially as
hereinbefore described and as illustrated by Figure 3 of the accompanying
drawings.
5. Vanes for impact water wheels constructed and arranged substantially as
herein before described and as illustrated by the accompanying drawings.
6. An impact water wheel constructed and arranged with oblique vanes sub-
stantially as hereinbefore described and as illustrated by the accompanying
drawings.
