declare the nature of this invention to be as follows :—
The invention consists of a wheel mounted on a hollow shaft, said wheel may
have two sets of radial channels leading in opposite directions to peripherial
surface of the wheel, the outside has double rings of vanes divided by a partition;
said vanes are also curved in opposite directions. When the motive agent is
passed through one set of channels and vanes the wheel rotates in one direction.
To reverse the motor the motive agent is passed through the opposite set of
channels and vanes. The motive agent after issuing from the channels is
conducted through stationary guides or vanes, after leaving said vanes or guides
it acts on vanes attached to the wheel. The stationary vanes described which
may be fixed to a case or disc may rotate in an opposite direction to the wheel
described so that the motive agent after passing through one wheel may act
directly on the second wheel these wheels may be formed to have the motive
agent act once or any number of times on each wheel. To shut off or change the
motive agent from one set of channels and vanes to the other we provide a ring
valve intermediate said channels and vanes said ring valve having ports corre-
sponding with the forward and backward ports in channels. To run the motor
forward the ring valve is rotated until its ports register with one set of channels;
to reverse the motor the ring valve is moved back until the opposite ports open.
Motion may be given to the ring valve through a sliding sleeve on the motor shaft
said sleeve having a spiral groove engaging with arms attached to the ring
valve. Sometimes to simplify the motor we may use a tubular valve in the
hollow shaft instead of the ring valve. This valve may be connected to the
sleeve described by a pin passing through a slot in the shaft. When the sleeve
and valve are moved towards the wheel the ports in the valves come fair with
one set of channels; when moved from the wheel the valve ports come fair with
the opposite set; the sliding sleeve may be operated by a lever or other means.
To regulate the speed of the motor a governor may be placed in each channel;
as the speed increases the governors press out against the springs and partially
close the ports, when the speed is normal the springs hold back the governors.

page_text: Other governors may also be used. When these wheels are intended to run in
one direction all channels and vanes are curved to suit one direction of rotation
only.

MORRISSEY, Farmer, The Pike, Dungarvan, and MICHAEL O'CONNELL, Engineer,
Cappoquin, all in the Co. Waterford, dohereby declare the nature of this invention
and in what manner the same is to be perforined to be particularly described and
ascertained in and by the following statement:-
This invention consists of a central reaction wheel mounted on a hollow shaft
and provided with say two sets of radial channels leading in opposite directions
to the peripheral surface of the wheel. The outside has double ring sets of vanes
divided by a partition, these vanes are also curved in opposite directions and
these we call the impact wheel. When the steam or other motive agent is
passed through one set of channels and vanes the central wheel rotates in one
direction. To reverse the motor the steam is passed through the opposite set of
channels and vanes. The steam or other motive fluid after issuing from the
channels is conducted through stationary guides or vanes, which we call a
deflector and passing from thence it acts on vanes attached to the central wheel.
The aforesaid stationary vanes (the deflector) which are fixed to a case or disc may
as a modification be made to rotate in an opposite direction to the central wheel
described so that the steam after passing through one wheel acts directly on
the second wheel. The steam or other motive agent may act once or any suitable
number of times on each wheel.
To shut off or change the motive agent from one set of channels and vanes
to the other we provide a ring valve intermediate of the said channels and vanes,
said ring valve having ports corresponding with the forward and backward ports
in the channels. To run the motor forward the ring valve is rotated until its

page_text: ports register with one set of channels. and to reverse the motor the valve is
moved until the opposite ports open. Motion may be given to the valve by a
sliding sleeve on the motor shaft, said sleeve having a helical groove or slot
engaging with a projection or arms on the ring valve. Sometimes we may use a
tubular valve in the hollow shaft instead of the ring valve. This valve may be
connected to the aforesaid sleeve by a pin passing through a slot in the shaft.
When the sleeve and valve are moved towards the central wheel the ports in the
valve come fair with one set of channels and when moved from the wheel the valve
ports come fair with the opposite set of channels. The sliding sleeve may be
operated by a lever or by other suitable means. To regulate the speed of the
motor a governor in the form of a valve may be placed in each channel of the
central wheel and as the speed passes beyond the normal the governors press out
against springs and partially close the ports.
Fig. 1 is a sectional side elevation and Fig. 2 a transverse section of a turbine
motor constructed according to this invention. Fig. 3 is a face view of a reversing
valve and Fig. 4 a plan view of a sliding sleeve for shifting the valve, Fig. 5 is
an enlarged side elevation of the valve of the governor and Fig. 6 a sectional
plan of same.
A is the casing of the motor, and B the shaft which works in bearings C;
part of the shaft is hollow to connect with the steam or other motive fluid supply.
On the shaft B and within the casing A is fixed a central reaction wheel J
having sets of radial channels a and two sets in this example. and bare
branch channels set in opposite directions to the peripheral surface of the wheel.
Hand H are two sets of curved vanes forming a deflector secured to the sides of
the casing A and arranged one alongside the other with an intermediate par-
tition H. The vanes are curved in opposite directions and open at their outer
edges into vanes I and I' which are secured to the central wheel J and are
curved oppositely to the vanes H H¹. The vanes I and 1' which we call the
impact wheel are separated by a partition 12 and form the outer part of the central
wheel, the boss of which is fixed on the shaft B and provided with a bevel
wheel K. On the boss of the casing A is fixed a bevel wheel L. and these two
wheels gear with a bevel wheel M on a shaft N which transmits the power from
the wheels J and A. E is a tubular valve adapted to slide in the hollow part B'
of the shaft B and connected to a sliding sleeve F by means of a pin 1 working
in a longitudinal slot in the boss of the wheel J. The inner end of the valve E is
provided with ports Q' to register either with the set of channels a or the set of
channels G is the lever engaging with the flanges F2 on the sleeve and
serving to shift the sleeve and the tubular valve for causing the motor to
rotate in one direction or the other. In the position shewn the ports Q¹ are cut
off from both sets of channels a and a'.
In each channel a and a¹ we provide a centrifugal governor for automatically
cutting off the steam when the speed passes beyond the normal. Each governor
consists of a valve N having grooves in its periphery for the steam to pass through
to the branch channels 6 or 6. Each valve has a stem N¹ and a disc N which
by the steam is pressed against a spring O. As the speed increases beyond the
normal, the valves partly or wholly cover the outlets to the branch channels until
the speed is reduced, the springs then returning the valves to their normal
position.
Figure 3 is a ring valve provided with ports in the circumference and
which may be mounted between the casing A and one inner side of the then
widened casing A and to turn on the side of the wheel J within the inner or
vaned periphery of the wheel J. The channels h and b as well as the ports of the
ring valve would correspond in number with the channels a and a¹. The valve
is formed with two sets of ports, one set to register with the
branch channels and the other set with the branch channels b¹.
The ring valve is provided with spokes E attached to a boss E concentric
with the shaft B and provided with a pin E³ which would engage with a helical

page_text: groove in the sleeve F' Fig. 4 mounted to slide longitudinally on and turn with
the shaft B.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
what we claim is:-
1. A turbine motor provided with a central reaction wheel a direct impact
wheel which receives the motive fluid from the central reaction wheel, a deflector
intermediate of both said wheels and a reversing valve for admitting the motive
fluid to the reaction wheel substantially as set forth.
2. A turbine motor provided with a central reaction wheel having main
channels and branch channels leading in opposite directions from the main
channels a direct impact wheel which receives the motive fluid from the central
reaction wheel, a deflector intermediate of both said wheels, and a governor in
each aforesaid main channel for controlling the admission of the motive fluid to
the branch channels substantially as set forth.
3. The construction of turbine motor shewn on the drawing.
