I, HENRY SIDEBOTTOM, of Flixton Road, Urmston, in the County of Lancaster,
Agent do hereby declare the nature of this invention to be as follows;-
-
My object is to form a water turbine from which better results can be obtained
than has hitherto been possible.
I accomplish this by fitting around the rim of a wheel of suitable diameter, in
a spiral form, a suitable tube or channel open at one side.
Í arrange a suitable jet of high pressure water to play at a suitable angle into
the open side of the tube or channel, causing the wheel to revolve with great force
and rapidity which can be utilized as required.

I, HENRY SIDEBOTTOM, of Flixton Road, Urmston, in the County of Lancaster,
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:-
My object is to form a water turbine from which better results can be obtained
than has hitherto been possible.
I accomplish this by fitting or forming around the rim of a wheel of suitable
diameter, in a spiral form, a suitable tube or channel open at one side.
Or, I may form a wheel of which the spiral tube or channel forms the rim or tyre.
This wheel is keyed to a suitable shaft or otherwise suitably formed to run in
suitable bearings.
By means of a pipe terminating in a suitable nozzle, or nozzles, I arrange that a
suitable jet or jets, of high pressure water shall play at a suitable angle, (prefer-
ably of from thirty to forty-five degrees) into the open side of the tube or channel.
The effect of this is to revolve the wheel with great force and rapidity, which
can be utilized by means of a pulley wheel upon the helixwheel shaft, or otherwise
as required.
Referring to the drawings sent herewith:-
Fig. 1, shows a side elevation of my apparatus in its simplest form, with the
external casing removed.
Fig. 2 is a cross section of the rim of the helixwheel, showing sectional form of

page_text: the spiral tube or channel, which I form preferably as shewn, but may in some
cases form of a semicircular or other section.
In both Figs. a indicates the helixwheel around the rim 6 of which is attached
(or formed) the open tube or channel c in a spiral or helical form. d indicates a
high pressure waterpipe terminating in nozzle e, from which a jet of high pressure
water plays into the open side of channel c, revolving it upon shaft f, upon
which is keyed pulley wheel g, from which the power can be taken to any place
desired.
Having now particularly described and ascertained the nature of
my sait
invention and in what manner the same is to be performed, I declare that what
I claim is:
1st. The combined apparatus, substantially as described and shown, hereinbefore
and in the accompanying drawings, for the purposes set forth.
2nd. The combination, in water turbines and the like, of a helical channel open
at one side, with a nozzle or nozzles to direct high pressure water at a suitable
angle, into the side of the same, substantially as described and shown hereinbefore
and in the accompanying drawings.
