PROVISIONAL SPECIFICATION.
An Improved Motor Engine.
1, HERMANN BETTEN, Manufacturer, of Hegensdorf, near Büren, in the Kingdom of
Prussia and German Empire, do hereby declare the nature of my said invention to be
as follows
This invention refers to a rotary motor engine comprising one or two cylinders and
which can be operated by steam, gas, or petroleum, or other motive fluid.
In one form of motor according to this invention the casing of the motor is formed
of two portions, bolted together, and provided with a base. This casing is provided
with an inlet and an outlet for the motive fluid. The two portions of the casing
are of dished form, being provided at their periphery with a semicircular channel,
which form a circular cylindrical chamber in which work the pistons of the
motor.
The main driving shaft is mounted and runs freely in the centre of the casing,
being also supported by bearings outside the casing. On this shaft, and within the
casing, is keyed the motor wheel. The periphery of this wheel is divided into two
segments, each segment being provided at one of its ends with a spoke attaching it to
the boss of the wheel. These two segments of the motor wheel run in the circular
cylindrical chamber before mentioned, and at the end where they are joined to the
spoke, are provided with an enlargement occupying the total area of such cylindrical
chamber, which forms the piston of the motor. These pistons may be provided with
packing rings and constructed in any suitable way. The two segments of the motor
wheel, as before mentioned, run in the circular cylindrical chamber and are of
semicircular formation, and by being drawn in an inward direction by means of
springs attached to the boss of the wheel, they serve to close the groove, formed in
the inner surface of such chamber, for the passage of the spokes of the wheel, thus
rendering the chamber steam tight.
A flap valve is arranged in this chamber at the inlet port for the motive fluid,
which causes such fluid to exert its pressure in one direction only, and is automatically
closed by the passage of the pistons.
In operation, steam or other fluid under pressure being admitted through the
inlet port, the piston in advance is rotated in the circular cylindrical chamber until
the exhaust port is reached when such fluid escapes, the second piston in turn coming
under the influence of the motive fluid. As these pistons are connected with the motor
wheel and as such motor wheel is keyed on the main driving shaft, the desired power
is produced.
A modification of the flap valve above mentioned may consist of a disc or
shutter working in grooves and held by means of a rocking arm and spring, against
the periphery of the motor wheel, thus dividing the cylindrical chamber into a
pressure and an exhaust portion. The disc or shutter is opened by the revolving
piston striking upon its rocking arm, thus pressing the shutter into its grooves and
leaving a free passage for the piston. With this form of valve may be employed
a cut off or expansion valve worked off an eccentric provided on the main
driving shaft.
Another modification of this valve may consist of a rocking arm pivotted midway,
or nearer to one end than the other. Through this rocking arm is carried the steam
or other fluid pressure inlet, and its operation is, that when the valve-is obstructing
the cylindrical chamber and laying upon the periphery of the motor wheel, the inlet
duct for the fluid pressure is open, but when the valve is pressed back out of the
cylindrical chamber by the advancing piston, pressure is cut off.

page_text: Another modification of my invention, the spokes of the motor wheel are not
rigidly connected with the two segments of the tire, but adjustably, by means of
a connecting bolt and nut.
The pistons of the motor wheel may be provided with an expanding mechanism,
which may consist of a coned wedge piece inserted between two internally coned
rings carried on such piston. The coned wedge is forced between these coned rings
by means of a lever adjustably connected with the boss of the wheel.
As before mentioned I may provide a motor, according to this invention, with
two cylindrical chambers. These chambers are provided with one piston each, and
are alternately operated, and may be arranged upon the compound principle.

An Improved Motor Engine.
1, HERMANN BATTEN, Manufacturer, of Hegensdorf, near Büren, in the Kingdom of
Prussia and German Empire, do hereby declare the nature of this invention and in
what manuer the same is to be performed, to be particularly described and ascertained
in and by the following statement :-
This invention refers to a rotary motor engine comprising one or two cylinders
and which can be operated by steam, gas, or petroleum, or other motor fluid.
In one form of motor according to this invention the casing of the motor is formed
of two portions, bolted together, and provided with a base. This casing is provided
with an inlet and an outlet for the motive fluid. The two portions of the casing are
of dished form, being provided at their periphery with a semi-circular channel,
which forms a circular cylindrical chamber in which work the pistons of the
motor.
The main driving shaft is mounted and runs freely in the centre of the casing,
being also supported by bearings outside the casing. On this shaft, and within the
casing, is keyed the motor wheel. The periphery of this wheel is divided into two
segments, each segment being provided at one of its ends with a spoke attaching it
to the boss of the wheel. These two segments of the motor wheel run in the circular
cylindrical chamber before mentioned, and at the end where they are joined to the
spoke, are provided with an enlargement occupying the total area of such cylindrical
chamber, which forms the piston of the motor. These pistons may be provided with
packing rings and constructed in any suitable way. The two segments of the motor
wheel, as before mentioned, run in the circular cylindrical chamber and are of
semi-circular formation, and by being drawn in an inward direction by means of springs
attached to the boss of the wheel, they serve to close the groove, formed in the inner
surface of such chamber, for the passage of the spokes of the wheel, thus rendering
the chamber steam tight.
A flap valve is arranged in this chamber at the inlet port for the motive fluid,
which causes such fluid to exert its pressure in one direction only, and is automatically
closed by the passage of the pistons.
In operation, steam or other fluid under pressure being admitted through the inlet
port, the piston in advance is rotated in the circular cylindrical chamber until
the exhaust port is reached, when such fluid escapes, the second piston in turn coming
under the influence of the motive fluid. As these pistons are connected with the
motor wheel and as such motor wheel is keyed on the main driving shaft, the desired
power is produced.
A modification of the flap valve above mentioned may consist of a disc or shutter
working in grooves and held by means of a rocking arm and spring, against the
periphery of the motor wheel, thus dividing the cylindrical chamber into a pressure
and an exhaust portion. The disc or shutter is opened by the revolving piston
striking upon its rocking arm, thus pressing the shutter into its grooves and leaving

fixed to the wheel h the said wheel with all its parts follows the movement and sets
the shaft g in rotation, from which shaft the motion can be conveyed as desired.
the pistons n n' pass the duct d' the steam is exhausted.
As
With reference to the Figures 3 to 8, in Figure 3 the parts are arranged to provide
more perfect fitting between the parts acting as the pistons n of the motor and the
valve s.
To this end the valve s is replaced by a sliding plates which, by means of a
spring s² is pressed against the inner rim of the piston body or wheel. The plate s'
is movable to and fro in the grooves 3 on the casing a and in order to move it back
and allow the passage of the piston n there are provided on the piston raised circular
ribs which when the shaft rotates come against the springs and press it and
thereby move the plate s back and thereby allow the passage of the piston.
A is a double acting cock which is given, by means of the eccentric B and
its rod, an oscillating motion and thus opens either its duct or passage A' or A² to
the steam pipe C. This cock A serves to cut off the steam and provides for a
fixed expansion.
Instead of constructing the wheel piston as above described it can be constructed as
shewn in Figures 5 to 8. In this case the spokes i of the piston are not rigidly fixed
to the rim t but are fitted into a cavity therein and by means of the adjusting
screws and their nuts ³ the correct adjustment can be given to the piston rim t.
The springs ppl are done away with in this modification, and instead of the valve
a rocking valve D) is provided which conducts the steam and at the same time acts as a
thrust piece. The valve D is closed at D' when it is pressed back to allow for
the passage of the piston n. The spring D2 is provided to cause the opening of the
valve and to insure the valve fitting up to the piston rim t. Figures 6 and 7 shew
the valve D in detail. The width of the valve at D³ is the same as the piston n and it
slides in the groove D in the casing. The piston n can also be constructed as shewn
in Figures 5 and 8 in order to obtain an easier fitting. In this case each piston is
provided with a conical piece K which can be moved to and fro on the piston screw K¹
by means of a lever K². The lever K2 is adjusted by means of the screws K³ in
connection with lugs K on the centre of the wheel, so that by tightening the
screws K³ the cone K can be moved. The cone K is within a hollow cone L
over which the spring M (having a slit M') rests. By tightening the screws K³ the
fit can be regulated.
The adjusting screws t³ K³ can be easily set by means of an opening in the
casing a without taking the cylinder to pieces.
Figures 9 to 12 shew the engine with two cylinders having one piston n in each.
These are independent one of another and work alternately. The two-cylinder motor
effects a considerable saving and utilization of the steam.
The entrance of the steam takes place at c Figures 9 and 12, and the exhaust at c¹.
The exhaust port is of oval shape to prevent the tightening piece of the piston which
serves as a spring from catching. The regulation of the expansion is effected by the
eccentrics B and rods F see Figure 10. On the rods F there are two movable heads G
against which a crank attached to the shaft H strikes. The shaft H is in two parts
so that the supply valves may work independent of each other.
By moving these heads G to a greater or lesser distance the entry of the steam can
be regulated at pleasure. The lubricating of the cylinders is effected through the
lubricating duct W when the valve I moves back when the oil drops onto the valve
and is blown into the cylinder when the valve is opened. It is self evident that with
this arrangement there must be two eccentrics provided and the valves which
are in connection with them, by the rods F, are actuated through the shaft H from
without.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed, I declare that what I
claim is
1 A single or double cylinder rotary motor engine having a divided casing ɑ. a

page_text: wheel h having pistons n carried by spokes i, and a rim t having a cross section as
shewn, and plates m and m' which carry said pistons n, short spoke pieces e and el
having springs p and p' which press by means of the bolts q, the rim t firmly

4. The arrangement of the cone K which is movable on the piston screw K¹ inside
of the pieces L and around which the spring M laps, so that by moving the
screws K³ the pistons can be adjusted by the levers K² from the inside, as shewn at
Figures 5 and 8.
5. In a rotary motor engine as claimed in Claim 1, the arrangement of the slide s¹
pressed by the spring against the rim t, and removing said slide, to allow the
piston n to pass by means of ribs son said pistons n, as shewn in Figures 3 and 4.

described and having the expansion regulated by means of the rods F and adjustable
parts G as shewn at Figures 9 and 10.
7. In a rotary motor engine as claimed in Claim 1, lubricating the cylinder by
means of the channel W, so that the oil drops onto the inlet valve D and is blown into
the cylinder on the entry of the steam.
