PROVISIONAL SPECIFICATION.
A New or Improved Motor.
We, WILLIAM WERNER, of 14 Glendall Street, Stockwell, in the County of
Surrey, Draughtsman, and WILLIAM THOMAS PRUDAN of 1 Bellevue, Pulross
Road, Brixton, also in the County of Surrey, Mechanical Engineer, do hereby
declare the nature of this invention to be as follows:-
:-
This invention relates to a new or improved hydraulic motor in which the same
water, or other fluid, is used over and over again, there being no loss of propelling
fluid whatever except by evaporation.
According to this invention we provide a suitable tank or other vessel having
an outlet pipe at its lower side and suitably supported over a series of water-
wheels to be hereinafter described. The said outlet is arranged to discharge the
liquid from the tank into the buckets of the upper of the said water-wheels. As
this wheel, rotates by the weight of the liquid it delivers the liquid into a trough
by which it is conveyed to a second and similar wheel which is rotated by it in a
like manner.
After passing over and rotating a series of such wheels the liquid is
passed over a larger wheel or wheels into a collecting trough. The upper wheels
work independently of each other and are suitably geared to centrifugal pumps or
other devices for raising liquids which are employed to raise the liquid from the
collecting trough and return it to the upper tank in order that it may be again
employed to actuate the series of water-wheels. The lower wheel, or wheels, is, or
are, connected to the main shaft of the apparatus from which the power developed
may be taken off by means of endless bands or other mechanical means.
It is found in practice that the smaller and upper wheels of the series are
capable of operating pumps or other liquid-raising devices of such capacity that
more water or other liquid may be by their means, returned to the upper tank than
is discharged over the said small wheels of the series. This fact is taken advantage
of in this apparatus by the employment of pumps or other like devices of such large
capacity that an overflow pipe has to be provided to maintain the level of the
liquid in the upper tank. This overflow pipe is arranged to discharge the excess
of liquid directly into the buckets of the lower and larger wheels of the series,
namely those from which the power is taken, so that the power developed by the
motor is considerably increased.

COMPLETE SPECIFICATION.
A New or Improved Motor.
We, WILLIAM WERNER, late of 14 Glendall S. Stockwell, in the County
of Surrey, but now of 2 Laurel Terrace, Hampi Hill, in the County of
Middlesex, Draughtsman, and WILLIAM THOMAS PRUDAN, of 1 Bellevue,
Pulross Road, Brixton, in the County of Surrey, Mechanical Engineer, 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 a new or improved hydraulic motor in which the same

page_text: water, or other fluid, is used over and over again, there being no loss of propelling
fluid whatever except by evaporation.
According to this invention we provide a suitable tank or other vessel having an
outlet pipe at its lower side and suitably supported over a series of water-wheels to
be hereinafter described. The said outlet is arranged to discharge the liquid
from the tank into the buckets of the upper of the said water-wheels. As this
wheel rotates by the weight of the liquid it delivers the liquid into a trough by
which it is conveyed to a second and similar wheel which is rotated by it in a like
manner. After passing over and rotating a series of such wheels the liquid is
passed over a larger wheel or wheels into a collecting trough. The upper wheels
work independently of each other and are suitably geared to centrifugal pumps or
other devices for raising liquids which are employed to raise the liquid from the
collecting trough and return it to the upper tank in order that it may be again
employed to actuate the series of water-wheels. The lower wheel, or wheels, is, or
are, connected to the main shaft of the apparatus from which the power developed
may be taken off by means of endless bands or other mechanical means.
It is found in practice that the smaller and upper wheels of the series are capable
of operating pumps or other liquid-raising devices of such capacity that more water
or other liquid may be by their united means, retiirned to the upper tank than is
discharged over the said small wheels of the series. This fact is taken advantage
of in this apparatus by the employment of pumps or other like devices of such large
capacity that an overflow pipe has to be provided to maintain the level of the
liquid in the upper tank. This overflow pipe is arranged to discharge the excess
of liquid directly into the buckets of the lower and larger wheels of the series,
namely those from which the power is taken, so that the power developed by the
motor is considerably increased.
And in order that our invention may be more fully understood and carried into
practice we will now proceed to describe the same with reference to the accom-
panying sheet of drawings illustrative of a motor constructed according to this
invention:
As will be seen from an inspection of this drawing the motor consists of a series
of water-wheels a provided with buckets upon their peripheries mounted on a
suitable framework bone over the other, the whole series, together with a larger
wheel placed below the wheels a being arranged below a tank or reservoir d
supported on the top of the framing b. A. collecting tanke is placed in the base
of the framework to receive the water or other motive liquid employed.
The spindles of the water-wheels a, c, are supported in suitable bearings on the
framework so that they may turn independently of one another. The said wheels.
are provided with suitable casings which are connected by shoots y so that water
or other liquid may be conducted from one to the other and splashing prevented.
A suitable pipe or conduit is provided to allow of the passage of the water
from the tank d'on to the periphery of the uppermost wheel a. The opening into
this conduit may be provided with a suitable valve j in order that the motor may
be stopped and started and its speed regulated as required.
Each of the wheels a is geared, either directly as shown, or through the agency
of any suitable mechanism, to a centrifugal pump or other suitable device k for
raising liquid, the suction pipe of each of which dips into the collecting tank e
and the delivery pipes m from each pump k pass upwards and discharge into the
upper tank d. Though in the drawing the pumps k are each shown mounted on a
level with the wheel a by which it is driven, in some cases it may be advisable to
fix the pumps at the base of the motor so as to reduce the length of the suction
pipe-in this case suitable gearing would be interposed between each wheel
its pump k. The tank dis provided with an overflow pipe n which passing
downwards breaks through the casing on the large wheel and discharges into
the buckets of the same. The spindle of the large wheel is provided with
belt, toothed, or other gearing for transmitting the power developed by the
motor.
and

page_text: Though but three wheels a are shown in the drawing it is obvious that a greater
number may be employed, each having its own pump or other water-raising
device connected with it in the manner described. When a great number of these
wheels are employed they may be arranged in a number of series such as that
The
described, and working in connection with one or more large water-wheels c.
greater the number of the wheels a employed, the greater will be the excess of
water returned over that required to rotate the said wheels and consequently the
greater will be the overflow and the power developed by the motor.
As the wheels a are operated solely by the weight of the water in their buckets
and not by the force of the same falling from a height, it is obvious that its effect
upon the last wheel of the series is as great as it is upon the first wheel. It is for
this reason that the number of wheels constituting the series may be modified us
already described.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
An hydraulic motor cousisting of a series of water-wheels placed one above the
other and arranged to work independently, each wheel being made to operate a
separate pump or other liquid-raising device so arranged as to return a portion of
the water passing over the wheel to a tank placed at the top of the motor from
which the water descends on to the uppermost of the series of wheels and on to
each of the other wheels in turn. Below this series of wheels a water wheel or
wheels of larger diameter is, or are mounted to receive the water after it has
traversed the series of wheels referred to. The tank at the upper portion of the
device is provided with an overflow pipe arranged to discharge into the buckets on
the large wheel or wheels at the bottom of the series, the shaft of which is pro-
vided with belt, toothed, or other suitable gearing for giving off the power
developed. The whole device being provided with the necessary collecting tank
at its base, casings, shoots, piping, framework, etc., substantially as and for the
purpose hereinbefore described and illustrated in the accompanying drawing.
