A New or Improved Rotary Motor, applicable as a Pump, Exhauster,
or Blower.
I, JOHN Mossop of Bridge End Tannery, Egremont, in the County of
Cumberland, Tanner, do hereby declare the nature of this invention to be as
follows:-
This invention relates to a new or improved motor to be actuated by fluid pressure,
i.e. steam, hot or cold air or gases, water or other liquid under pressure; or by
pressure and suction combined.
SO
In carrying this invention into practical effect, I mount two dises upon a shaft
and connect their inner sides or faces by a series of radial vanes, floats, or leaves,
extending from the periphery of the said discs inwards towards, but not up to, their
The star wheel
centres, so as to leave an open space around the said shaft.
formed is enclosed in a suitable casing provided with suitable bearings for carrying
the shaft. Inlet and outlet ports or ways are formed in the said casing, over or
around a portion of the periphery of the said "star wheel" up to which they are
made to fit closely. A stop, slide, or other similar device may be arranged in the
casing at a point about half way between the inlet and outlet ports and may be
employed for the purpose of checking the waste of the propelling fluid passing over
the vanes without pressing against them in its course through the apparatus.
Suitable guides are provided and project inwards from the casing so as to
closely fit against the periphery of the "star wheel" to direct the pro-
pelling fluid against the vanes at or near their periphery centripetally into
and tangentially out from the wheel. The said casing closely fits the sides of
the "star wheel" but only fits its periphery at one point, and that about half
way between the inlet and outlet ports, i.e. the "star wheel" and its casing are
eccentric one with the other. The said point at which the "star wheel" and
casing meet is diametrically opposite to that at which the before mentioned
guides are placed. By this arrangement, it will be seen, the two points at which
the casing fits up to the periphery of the star wheel," the hereinbefore mentioned
guides being reckoned as part of the casing, are diametrically opposite one
another. A valve cock, or other suitable controlling device is placed in the
overflow or exhaust pipe in order to afford a means of checking the outflow of
the propelling fluid so that it may be constant or continuous and may not become
too quickly exhausted, and also to allow of the full power of the propelling
fluid being admitted to the wheel and permitted to escape therefrom for temporary
purposes when required. A governor and throttle valve, or other device for
regulating the speed may be placed in the outflow or exhaust cock but not
between it and the motor.
With the engine or motor thus constructed the propelling power enters the
wheel by the inlet port or way and impinges or presses against the vanes centri-
petally at or near their periphery and on to a point half way between the points
of inlet and outlet and simultaneously fills the body of the wheel at full pressure,
the propelling power then forcing the wheel round on its axis enters the outlet
port or way pressing against the vanes tangentially to the outlet.
The stop tap or cock in the outlet or exhaust pipe or conduit is of consider-
able importance as a means of keeping the body of the wheel well filled with
the propelling power at full pressure materially assisting in forcing the propelling
power to pass through the wheel by the inlet and outlet ports or ways with the
greatest advantage possible.

page_text: Different arrangements of motors can be adapted and used reversably and
some of the types reversably at either end without materially interfering with
their efficiency as engines or motors.
In some cases I find it advisable to combine two such motors as hereinbefore
described. Such compound motor is formed of two star wheels" placed side
by side on the same axis and enclosed in one casing which fits closely to their
sides and envelopes the shaft by which they are connected. Sufficient space is
allowed between the shaft and the central portion of the casing to permit of
the passage of the motive fluid from one wheel to the other, and certain of the
vanes of the wheels may be produced to and along this shaft to which they
may be connected. The inlet port is formed in the casing around the periphery
of one wheel and the outflow port is constructed in the casing formed around the
periphery of the other wheel, both ports extending over about half the periphery
of the wheels. The motive fluid enters the first wheel and carries it round with
it and passes through the open spaces near its centre along the tubular casing
around the shaft or spindle and enters the body of the second wheel. It then
impinges against the vanes of this second wheel at or near its periphery passing
around it to the outflow port in the casing.
Motors constructed as described may be adapted without materially inter-
fering with their principles of construction-as to be used for the purpose of
blowing or exhausting at high or low pressure, or for the purpose of drawing or
forcing water at high or low pressure-or so as to be used as motors.

COMPLETE SPECIFICATION.
A New or Improved Rotary Motor, applicable as a Pump, Exhauster,
or Blower.
I, JOHN Mossor, late of Bridgend Tannery, Egremont, in the County of
Cumberland, but now of Richardson Place, Main Street, St. Bees, also in the
County of Cumberland, Tanner, 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 relates to a new or improved motor to be actuated by fluid
pressure, i.e. steam, hot air, or gases.
In order that my invention may be more fully understood and carried into
practice I will now proceed to describe the same with reference to the accom-
panying sheet of drawings of which
Figure 1 is a longitudinal, and Figure 2 a transverse section of a motor con-
structed according to my invention.
In carrying this invention into practical effect I mount two discs a upon a
shaft and connect their inner sides or faces by a series of radial vanes or
leaves c extending from the periphery of the discs a inwards towards but not
up to their centres, so as to leave an open space d around the said shaft b.
The "star-wheel " so formed is closely enveloped by a suitable casing e provided
with suitable bearings for the shaft which passes through the stuffing boxes
formed on the casing e. Inlet and outlet ports are formed in the said
casing e over or around a portion of the periphery of the said "star-wheel."
A slide valve h being provided to connect one or other of the said ports with
an exhaust passage j. A hand lever k or other suitable device is provided to
operate the said slide valve h which may be adjusted to control the amount of
a motive fluid passing through the motor, as will be readily understood upon an
inspection of the drawings.

Suitable guides are provided and project inwards from the casing so as to
fit against the periphery of the star-wheel to direct the propelling fluid
against the ranes c at, or near, their periphery centripetally into, and tangen-
tially out from, the wheel. The said casing e closely fits the sides of the "star-
wheel" but only fits its periphery at one point and that about diametrically
opposite the centre of the inlet and outlet ports. In other words, the "star-
wheel" and its casing are eccentric one with the other as shewn at Figure 2 of
the drawings, the guides being placed at a point diametrically opposite to that
at which the "star-wheel" and its casing meet.
A valve, cock, or other suitable controlling device, not shewn in the drawings,
is placed in the overflow or exhaust pipe j in order to afford a means of checking
the out-flow of the propelling fluid so that its passage may be constant or
continuous and may not become too quickly exhausted. A governor and throttle
valve or other device for regulating the speed may also be placed in the out-
flow or exhaust pipe.
With an engine or motor thus constructed the propelling power enters a
wheel by the inlet port or ways and impinges against the vanes centripetally
at or near the periphery and on to a point about halfway between the points of
inlet and outlet simultaneously filling the body of the wheel. The propelling
power then. forces the wheel round its axis and enters the outlet port or way
pressing against the vanes tangentially to the outlet, as indicated by arrows in
Figure 2 of the drawings.
The propelling fluid with which the body of the motor has been filled at full
pressure materially assists in forcing that portion of the propelling fluid that is
in motion against the vanes or leaves e tangentially at or near their periphery
outwards by the outlet port or way. The inner circle of arrows in Figure 2
illustrates this action. The accumulation of fluid about the centre of the wheel
thus serves to maintain the fluid on its passage through the machine in contact
with the vanes and acts as an elastic buffer or cushion gyrating in the body of
the wheel eccentrically with the same.
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 :-
:-
The construction and use of a rotary motor substantially as hereinbefore set
forth and described and illustrated in the accompanying drawings.
