PROVISIONAL SPECIFICATION.
Improved Methods or Means of or Apparatus for Driving Dynamos
or Electric Generators.
I PHILIP HENRY WILLIAMS Egham Surrey Gentleman do hereby declare the
nature of this invention to be as follows:—
Arranging dynamos or electric generators in the interior of or attached to water
wheels in such a way that it shall be connected to & be driven by the water wheel
& require only connecting apparatus to transmit the electricity and for this purpose
any kind of overshot or undershot wheel or turbine may be utilised but specially
the following-viz.: a small handy wheel that may be worked in any position or a
double turbine-the first may be described as a drum or pulley wheel with sides
enclosed containing the dynamo or electric generator and on the circumference
triangular or other form of floats best adapted for the position in which it has to
work whether attached to piers or slopes or other parts of weirs or at waterfalls &c.
or attached to floating piers or rafts or craft of any kind where a river or tidal
current can drive it. But for some positions I use a double turbine form of water
wheel one spindle of which is tubular and works on the spindle of the other or lower
wheel & which are both so feathered that they shall be driven in opposite directions
and thus with the inner spindle carrying one part of the dynamo or electric
generator and the other or tubular spindle the other part in opposite directions
double speed is obtained. I also drive dynamos or electric generators in a similar
manner as with double turbines-one half on its spindle to face the other half on
its spindle, with or the circumferences of such fans or blades or circular facings with
cavities therein to work against the facings of fixed tubular rings to which the
power is conveyed and provide in the said rings apertures or outlets at such angles
as shall direct its force against the fans or blades or cavities and drive each part of
the dynamo in opposite directions and I make the outlets so grouped that no dead-
point shall exist. These may be made in single form to drive one part only of the
dynamo as in the case of the first described small water wheel.

COMPLETE SPECIFICATION.
Improved Methods or Means of or Apparatus for Driving Dynamos
or Electric Generators.
I PHILIP HENRY WILLIAMS of Egham Surrey Gentleman 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 is the providing of spaces in the interior of wheels and arranging
dynamos or other electric generators therein.
They may be in the form of drums or pullies or otherwise and may be provided
with floats or arms & bands and floats or be without floats so that they may be
driven by water with floats or by belt or other means.
Likewise these wheels & spaces &c. may be made to form the shaft of wheels as
see example shown in Specification 927400 Fig. 8, which may be arranged to allow the
armature of the dynamo to pass through the bearing of the drum or wheel so that
its spindle may work therein also & be driven by belt or other meaus in the opposite
direction to the wheel carrying other part of the dynamo, to gain double speed or
[Price 4d.]

page_text: the said armature spindle be fixed to prevent revolving which is single motion.
The example is an undershot wheel but the same applies to overshot.
Likewise these wheels may be used to be attached to the shaft of wheel, as shown
example of in Specification 849500 in the drum form on shaft or axle of railway
wheels in Fig. 1, or may be attached to other wheels as shown example of in same
in Fig. 3.
Also they may be made in pairs one wheel to carry one part of the dynamo &c.
& another the other part so as to work face to face in opposite directions to gain
double speed by belt or other means or made to be attached to double shaft,
attaining the same object, as shown example of in Specification 92740 attached to
the shafts of a double turbine and which may be so worked in other positions & by
other wheels or may be provided with a flange or otherwise and worked by belt
either double or single motion-but for single motion it may be used in present
overlapping form by fixing the axle of the inner wheel. For single motion however
the examples in Figs. 4, 5 & 6 afford more simple forms & means being on fixed
spindles carrying the part of the dynamo intended to be stationary.
These may be worked in any position & by changing the form of their floats they
may be made overshot wheels or by dispensing with floats they may be driven by
belt or other means or by attaching to other wheels or shafts as herein before
stated.
While any kind of floats may be employed or attached to these wheels I provide
for undershot wheels an improved form of float to obviate the checks & vibrations
caused by ordinary floats striking the water. This is an angular float as shown
examples of in Figs. 4 & 5 in Specification 92740. Moreover these wheels may be
magnetized or made to form the magnets or parts of the dynamos &c. they are
arranged to carry and their influences also may be utilized as indicated in Specifi-
cations 927400 & 8495*0.
Likewise the spaces may be lead lined & hermetically sealed or other metal may
be used for the purpose and the said wheels & spaces may be used for any of the
purposes mentioned or required in the above mentioned Specifications or other of
my Specifications or inventions.
Moreover as all dynamos can be alternately used or employed as generators or
motors so these several forms of wheels & spaces provided therewith may be so used
or employed.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is separately & combined
1st. The providing of spaces in the interior of wheels with or without floats or
arms bands and floats and arranging dynamos or electric generators therein as
indicated and described herein.
2nd. The improved or angular form of float likewise herein before described.
Dated this 1st day of April 1891.
