PROVISIONAL SPECIFICATION.
Improvements in Driving Dynamos and other Machinery by Water
Power.
I, JOHN EVELYN LIARDET of 16 Hyde Park Gate in the County of London,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention relates to the attachment of water motors in any convenient
position to or adjacent to water mains or to any subsidiary pipes to be connected to
such water mains whether in the roads, paths, or in any buildings, so that such
motors may be actuated by the pressure of the water passing through such mains
or pipes without in the least deteriorating the pureness of the water for
consumption.
According to this invention I fix in any suitable position to or in connection
with the water mains or main or subsidiary pipes one or more water motors, so as to
receive the force of the water when passing through or from such mains or pipes.
The vertical or horizontal shafts of the motors may be fitted with suitable tooth
or other wheel gearing to be attached to similar gearing on the counter shafting
when necessary to revolve a dynamo or dynamos for charging secondary batteries
to supply current for lighting, or the electric current may be procured direct from
the dynamo without counter shafting according to the speed required, and for
motive power purposes other than generating the electric current for lighting a
motor may be used in conjunction with the aforesaid machinery.
I provide all spindles or shafting with ball bearings in order to reduce the friction
to a minimum, and in order to obtain an equal flow of rapid-running water through
the mains or pipes. I attach suitable chambers to contain air under pressure so
that the water shall retain or keep its correct course to give off the greatest power
on the motor or motors for the purpose described.

Improvements in Driving Dynamos and other Machinery by Water
Power.
I JOHN EVELYN LIARDET of 16 Hyde Park Gate, in the County of London,
Engineer, do hereby declare the nature of this invention and in what manner the
same is is to be performed to be particularly described and ascertained in and
by the following statement :-
This invention relates to the attachment of water-motors in any convenient
position to or adjacent to water mains or to any subsidiary pipes to be connected to
such water mains, whether in the roads, paths or in any buildings, so that such
motors may be actuated by the pressure of the water passing through such mains
or pipes, without in the least deteriorating the pureness of the water for
consumption.
According to this invention I fix in any suitable position to or in connection with

page_text: .
the water main or mains or subsidiary, pipes one or more water motors, so as to
receive the force of the water; when, passing through or from such mains or pipes.
The vertical or horizontal shafts of the motors may be fitted with toothed or
other suitable wheel gearing to be attached to similar wheel gearing on the counter
shafting when necessary to work a dynamo or dynamos for charging secondary
batteries to supply current for lighting, or the electric current may be procured
direct from the dynamos without counter shafting according to the speed required,
and for motive power purposes other than generating.the electric current for lighting
a motor may be used in conjunction with the aforesaid machinery.
I provide all spindles or shafting with ball bearings in order to reduce the
friction to a minimum, and in order to obtain an equal flow of rapid running
water through the mains or pipes. I attach suitable chambers to contain air
under pressure so that the water shall retain or keep its correct course to give off the
greatest power on the motor or motors for the purpose described.
And in order that. my said invention may be more clearly understood I will now
proceed to describe the same with reference to the accompanying sheet of drawings,
in which Fig. 1 shews the general arrangement of my improved means for driving
dynamos and other machines by water power, as applied to a house or building,
Fig: 2 shews the application of my invention to the ordinary or to the additional
exit main or reservoir.
In Fig. 1. a.shews.the water main, b.the house supply,pipe c tank, d down pipe,
e water-motor, driving the dynamo f by means of the bevel gearing 9 (or if desired
I. may make use of other suitable gearing to effect the same object or I. may drive
the dynamo direct from the water motor e) h h shew accumulators, which I may
charge from the dynamo f so as to have a constant supply, of. the current, even when
the water motor is not working. jjshew brick, stone-work or other suitable
foundations for supporting the motor and dynamo. shews a compressed air
chamber to prevent the.. air and water concussion or fight, consisting, of the
pipe shewn in. dotted lines said pipe being a continuation of the down pipe d
for the fixed air to escape through as shewn by the arrows, flight .so as to
allow the water to run with its full force down the pipe. d. m shews ball-tap.

In Sheet 2.0. shews, broken section, of a reservoir water therein, p cap to rise
and fall and: ta guide. in which cap prises and falls, actuated by any suitable
machinery such as a winch (not..shewn in the drawing). is the down pipe to

furnished
The spindles is geared to or otherwise suitably connected with a dynamo or
other machine. t is the pipe by which the water runs away into the main after
actuating the motor r.
The action is as follows:-
.
The water enters from the main aand passes up the house supply pipe (in
Fig. 1) it then passes into the tank c, being controlled by the ball-tap m. The
water leaves the tank as shewn by the arrow, and descends the down pipe d, its exit
being controlled by the hand wheel.n, by means of which the water is admitted to
the motor. The water then revolves the motor e, which by means of the spindle
and gearing 9 actuates the dynamo for supplying current direct, or for charging
accumulators or secondary batteries. The water after working the water motor e
may escape into the sewers thus serving to keep them constantly flushed, or it may
under certain circumstances be returned to the main.
In Fig. 2 which shews my invention applied to. a reservoir, on the cap p being
raised-by means of any suitable lifting and lowering gear, the water from the reser-
voir o passes down the pipe g and operates directly on the motor r, which actuates
the spindle of the motor for driving a dynamo or other machine. The water then
passes down the pipe and, into the main.
I may either apply my invention to the existing mains, or have subsidiary mains
in which the water motors are fitted, as before described.

page_text: The direction of the course of the water through the mains and pipes is indicated by
the arrows.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manuer the same is to be performed I declare that what I
claim is :
1. In improvements in driving dynamos and other machinery by water power,
the attachment or use of water motors in the water mains of houses or other
buildings.
2. In improvements in driving dynamos and other machinery by water power,
the attachment or use of water motors in the water mains of houses or other buildings,
substantially as herein before described and represented on the accompanying sheets
of drawings at Figure 1.
3. In improvements in driving dynamos and other machinery by water power,
the attachment or use of water motors in the water mains leading from reservoirs.
4. In improvements in driving dynamos and other machinery by water power,
the attachment or use of water motors in the mains leading from reservoirs
substantially as herein before described and represented on the accompanying sheets
of drawings at Fig. 2.
5. The arrangement of means for utilising the flow of water through water mains
as hereinbefore described and represented by the accompanying drawings.
6. The improvements in driving dynamos and other machinery by water power,
