We, JOHN CHIDGEY, HENRY CHIDGEY and WILLIAM CHIDGEY, all of
Watchet, Somerset, Engineers, do hereby declare the nature of this invention to be
as follows:-
This invention consists in improvements in water motors of the turbine type.
According to this invention the water-wheel is contained within an air-tight
case and the water is delivered to the buckets through a horn-shaped inlet nozzle
fitted at the feeding end of the feed pipe. The nozzle is so shaped as to cause the
water to impinge upon the buckets at an angle which ensures less loss of power
than hitherto. The buckets are flanged and curved to a shape which assists this
object.
A vacuum is created at the outlet and, consequently, the discharge of water is
accelerated and less obstruction offered to the rotation of the water wheel.
The spindle of the wheel is securely packed to prevent access of air to the
interior of the case in which the wheel is contained.
Dated this 29th day of August 1893.

We, JOHN CHIDGEY, HENRY CHIDGEY and WILLIAM CHIDGEY, all of
Watchet, Somerset, Engineers, 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 consists in improvements in water motors of the turbine type.
According to this invention the water-wheel is contained within an air-tight
case and the water is delivered to the buckets through a horn-shaped inlet nozzle
fitted at the feeding end of the feed pipe. The nozzle is so shaped as to cause the
water to impinge upon the buckets at an angle which ensures less loss of power
than hitherto. The buckets are curved to a shape which assists this object.
A vacuum is created at the outlet and, consequently, the discharge of water is
accelerated, and less obstruction is offered to the rotation of the water-wheel.
Referring to the accompanying drawings, Fig. 1 represents a side elevation of a
water motor constructed and arranged in accordance with this invention. Fig. 2 is
a vertical longitudinal section, and Fig. 3 a vertical trausverse section. Keyed or
otherwise rigidly secured on the shaft a is the water-wheel b contained within the
casing c which it fits so closely as to leave little more than sufficient room for
proper rotation.
At the back of the casing c, which, as is usual, is made in two
parts arranged to be bolted together through a suitable flanged joint, is an inlet
hopper d in which is fitted a horn-shaped water inlet nozzle e communicating with
the water supply pipe f. By the use of the horn-shaped inlet nozzle e the
incoming water which drives the water-wheel is directed on to the buckets b¹ at
an angle of incidence which ensures less loss of power than in water motors of the
turbine type as hitherto constructed. The inlet nozzle is situated midway between
the sides of the water-wheel and is so set and situated that the water is shot into

page_text: the buckets with greater effect than heretofore. A vacuum is created at the
outlet of the casing c and hence the discharge of water is accelerated and less
obstruction is accordingly offered to the rotation of the water-wheel 6 by which
the shaft a of the motor is driven. The said shaft a is carried in suitable
bearings g and is fitted at each side of the casing c with glands or plates for
preventing access of air to the interior of the casing.
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 :-
A water motor of the turbine type, in which the water is fed to the water-wheel
through a horn-shaped or conical nozzle such as e so set and situated as to cause
the incoming water to act upon the water-wheel buckets with greater effect, and in
which the casing containing the water-wheel is approximately air-tight and affords
little more than sufficient room for the proper rotation of the water-wheel, sub-
stantially as herein before described with reference to the accompanying sheet of
illustrative drawings.
