An Improved Water Motor.
I, RICHARD BRAY of Armitage Crescent, Lockwood Huddersfield, Yorkshire,
Engineer, do hereby declare the nature of this invention to be as follows:-
This invention refers to motors driven by water power and the object of my
improvements is to increase the power of such machines, and, by rapid discharge
of the water from the buckets after each impact thereon, to obtain greater
efficiency.
For the purpose of my invention I mount the disc or wheel of the motor on an
axis journalled in bearings in a suitable frame or shell which may enclose the
motor.
On the periphery of the said disc or wheel I secure or form a number of buckets
arranged at equi distances apart. These buckets are preferably made with two
curved surfaces, or are double U shaped, and they project a short distance beyond
each side of the wheel or disc so as to expose the inner sides of the buckets,
which, together with the opposite or outer sides, are open to the machine. At one
side of the machine and in a suitable position over the path of the buckets are
secured two nozzles or pipes which are adapted to deliver water to each half of
The water
the double buckets as the latter are successively presented under them.
for imparting motion to the machine may be obtained from the town's mains or
from any suitable source of supply, the pressure or force of fall being regulated
according to the power it is desired to develop.
The impact of the two jets or columns of water on the buckets gives powerful
successive impulses to the motor, and by the construction of the buckets as set
forth, the water, owing to the force of each impact, is caused to fly off. or
immediately discharges at the open sides and therefore does not impede the motion
of the motor.

I, RICHARD BRAY, of Armitage Crescent, Lockwood, Huddersfield, Yorkshire,
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 refers to motors driven by water power, the object of my
improvements therein being to increase their power, and, by rapid discharge or
diffusion of the water from the buckets after each impact thereon, to obtain greater
efficiency.
For the purpose of my invention I mount the disc or wheel of the motor on an
axis journalled in bearings in a suitable frame or shell which may enclose the

page_text: motor. On the periphery of said disc or wheel I secure or form a number of
buckets or floats arranged at equi-distances apart. These buckets are preferably
made with two curved surfaces, or are double U shaped, and they project a short
distance beyond each side of the wheel so as to expose the inner sides of the
buckets, which together with the opposite or outer sides, are open to the wheel
chamber.
At one side of the motor and in a suitable position over the path of the buckets
are secured two nozzles or pipes which are adapted to deliver water to each half of
the double buckets as the latter are successively presented under them. The
water for imparting motion to the machine may be obtained from the town's mains
or from any suitable source of supply, the pressure or force of fall being regulated
according to the power it is desired to develop.
In order fully to describe and ascertain my invention, reference is herein had to
the annexed sheet of drawings illustrative thereof, wherein :-
Fig. 1 is front elevation of my improved water motor, the plate D' being
removed to shew the parts clearly.
Figs. 2 and 3 are sections of same taken respectively on lines a-b, and c—d of
Fig. 1.
Fig. 4 is a detail afterwards referred to.
Referring to Figs. 1, 2 and 3 on the drawings, letter A represents a disc or wheel
mounted on shaft B journalled in bearings C in the frame or shell D enclosing the
motor. On the periphery of the said disc or wheel are cast or attached buckets or
floats E arranged at equi-distances apart round the disc as shewn. These buckets
are made slightly wider across the base than at the outer ends and they project a
little distance beyond each side or face of the disc or wheel to adapt same to
receive two columns or jets of water from the nozzles or pipes F, F, projecting
into the wheel chamber a little to one side of the wheel A and directly over the
path of the buckets.
The floats or buckets are preferably made with two curved surfaces or channels,
open to the wheel chamber at both ends, in order that when the water has done its
work it shall be rapidly diffused or discharged into said chamber, the nozzles F, F,
being arranged a short distance apart somewhat as shewn so that the two columns
of water therefrom shall strike the curved surfaces of the floats on the sides
nearest the dividing bridge; or the impact may be on the centre or other part of
each channel or curved surface.
G is the water supply pipe coupled to the nozzles F by union H, and conveying
water thereto from the town's mains or other source giving the requisite pressure,
said pipe being provided with an ordinary valve (not shewn) for admitting or
shutting off the water and for regulating the supply.
The impact or pressure of the two columns of water delivered by the nozzles on
the curved surfaces of the buckets or floats E gives powerful successive impulses
to the motor which thereby attains a high rate of speed and develops sufficient
power to drive various descriptions of machines or mechanism.
Immediately the water strikes the surfaces of the buckets or floats it flies off or
discharges at each end thereof as illustrated by the arrows in Figs. 2 and 3.
By this rapid or instant diffusion of the water after it has done its work, the
motion of the motor is in nowise impeded or retarded, and greater efficiency and
power are obtained.
The waste water flows out of the wheel chamber through the discharge pipe I.
Cast on the inner wall of the shell D and on the plate D' bolted to said shell, are
semicircular flanges or caps D' for running off the water as it falls from the
buckets or floats E, and preventing it reaching the bearings C. As the pressure
of the water supply varies in different localities and according to the conditions
and position of fixing the motor, the orifices of the nozzles through which the
water is injected into the wheel chamber, are made of correspondingly larger or
smaller area to admit of a greater or less fall of water which shall compensate for
the difference in the pressure of the supply and give the results or power required.

page_text: The nozzles F, F, may be made in one piece with tapered bores, as shewn in
Figs. 1 and 2, but to avoid the trouble and loss of time which would be necessitated
in having to disconnect and remove them from the motor when found to be larger
or smaller in capacity than desired, I prefer to employ the construction shewn in
Fig. 4 where separate nipples or mouthpieces F1, F1, are screwed into the ends of
the nozzles or pipes F, F, and are easily interchangeable with nipples of larger or
smaller capacity without interfering with the connections.
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 :-
Firstly. In water motors, the wheel or disc A provided on its periphery with
buckets or floats formed to receive the impact of two columns of water in manner
and for purposes substantially as herein shewn and described.
Secondly. In water motors, the combination, of a wheel or disc on whose
peripheral surface are formed or attached buckets or floats E, E, having double
curved surfaces or two open ended channels, and the jets or nozzles F, F, arranged
over the path of the buckets or floats and adapted to deliver a column of water to
each curved surface or channel of same when presented thereunder in manner and
for purposes substantially as shewn and described.
Thirdly. The construction of nozzles or pipes F, F, with separate inter-
changeable nipples or mouthpieces substantially as described with reference to
Fig. 4.
