I, PETER NEN, Manufacturer, of Nenhammer, near Linz on the Rhine, in the
Province of Rhineland, and Kingdom of Prussia, do hereby declare the nature
of this invention to be as follows:-
The accompanying drawing on Sheet 1, Figures 1 and 2 in two longitudinal
sections placed at right angles to each other, and Figure 3 in a partial side-
elevation, as also on Sheet 2 Figures 4-6 with slightly altered details, illustrates
a new invention relative to a steam engine with a rotating piston, which is said
to be simple, compendious, and effective, and, in comparison with its efficiency,
of small size and requiring little space.
The lower piece A bears, fastened on the pedestals a, the cylinder B, which has
the form of a ring of an [ shaped cross-section, open to the ring centre; further.
the bearing E in which the axle D rotates. The piston C which rests on the axle
and rotates with it, fills up the inner free space of the ring B and closes steamtight.
at B by means of two tightening rings bb interlocking both parts.
The circular space S formed by B in the [shaped cross-section surrounding
the piston C forms the space for the steam, in which the steam enters by the collar K
and passage, escaping by the slit w and the collar L.
Passage is shut or open according to the position of the cock G. In the
body H a slide F is arranged shutting very tightly sideways and moving up and
down which, so long as steam enters into S through vis in its lowest position,
its under surface touching the circumference of C. In the position at the com-
mencement, the steam entering by v reaches the narrow space between F and the
flaps or wings C¹ which has been fastened by casting to C, and closely touches at
the side and the circumference the sides of B, and pushes the valve away from F,
thus turning the piston C, the axle 1) and the parts resting on the latter, the
pulley T etc.
If now by a corresponding revolving of G the further supply of steam is shut.
off, the steam works between F and C¹ first of all by expansion until at length,.
when C passes the slit w, it begins to issue forth-F being at the same time
drawn up high-in its appointed space I of the body H so that C¹ can pass freely
under F, and, in consequence of the active force of the movable parts regain its
original position.
By revolving G, vis again opened, and at the same time F again lowered,
the steam reissues forth between 1 and C¹, and the whole performance is once more
repeated. To set in motion F and G various mechanisms can be employed..
According to Sheet 1 F, which is hanging to the bar M by the rods h, g, and fi
and is continually drawn downwards by the spring i, is lifted up by the pressure
of the cam c, placed on the disk O, rotating with D, against the lower end (which
has been suitably equipped with the pulley d) of the rod e which is carried into
N and acts above upon the lever f.

Another contrivance to set F in motion is shown on Sheet 2 Figures 4-6, in
side elevation, longitudinal and transverse section. Here the space I in which
F moves upwards is not furnished at the top with a stuffing-box, but finished off
as a massive cap H¹, being thus entirely closed.
Instead of which on the side in a special lid V a stuffing-box ¹ is constructed,
in which a shaft ³ revolves which carries on the outer side a small pinion 2³,
on the inner a somewhat larger cog-wheel the teeth of which gear with a rack Z
on the one surface of the slide F, so that F by the revolution of is raised in the
one, direction, and lowered in the other.
The revolving of 24 is effected by a traverse piece W, which, swinging round the
pin wat bar U having at one end a toothed quadrantz, at the other a pulley d,
is ordinarily kept by means of the spring f¹ in the position represented in Fig. 4
adjoining the peg st, but at every revolution of the principal shaft D is moved
once to the left (Fig. 4.) by the cam c affixed to the disc O which works towards
the pulley d, in the direction of the shaft.
While this is going on z acts upon the pinion z¹ by which at the same time the
shaft and the larger cog-wheel 2 revolve, the latter catching in the pinion ³
Through these movements F in thus raised; when c has pressed d, the spring f¹
draws back the traverse piece W and with it all the other parts into their former
position by which F is likewise again pushed downwards into the first position,
as represented in Fig. 5.
The cock G is set in motion by the guide-pulley P together with the regulator Q
(Figs. 1-3). For this purpose P is composed of a number of disks lying close
to each other with a level descending edge k and the ascending edges k², k², ³,
placed towards each other, and a lever p. whose lower free end, by means of a
spring, continually grazes P is so arranged that it can be pushed either to one side
on its axle t, by means of the rectangular lever 7 which is attached to the bar R so
as to be capable of being turned and set in motion by Q and which, by the pin n
in the fork m of its lower end, is always gearing with the groove o at the round
head in front of p, thus alternately grazing one or the other of the disks of P;
or it can be pushed to the other side, when it is raised or lowered by the latter,"
.at the same time turning t and the toothed segment r attached to it round a corre-
sponding angle, whereby the cog-wheel s which is fixed upon the axle n of the
cock G and is gearing with r, is made to revolve.
In this manner an accurate self-acting alteration in the expansion directly. con-
trolled by the regulator is rendered possible.
The piston C works at the same time as fly-wheel, but it is self-evident that a
separate fly-wheel might likewise be present.

I, PETER NEN, Manufacturer, of Nenhammer, near Linz on the Rhine, in the
Province of Rhineland, and Kingdom of Prussia, 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:-
The drawing filed with the Provisional Specification, on Sheet 1 Figs. 1
and 2 in two sections placed at right angles to each other, and Fig. 3 in a partial
side-elevation, as also on Sheet 2 Figs. 4-6 with slightly altered details, illustrates

a new invention relative to a steam engine with a rotating piston, which is said to
be simple, compendious, and effective, and, in comparison with its efficiency, of
small size and requiring little space.
The lower piece A bears, fastened on the pedestals a; the cylinder B which has
the form of a ring of a [shaped cross-section, open to the ring centre; further
the bearing E in which the axle D rotates. The piston C which rests on the
axle D and rotates with it; fills up the inner free space of the ring B and closes
steamtight at B by means of two tightening rings 6 6 interlocking both parts.
The circular space $ formed by B in the [shaped cross-section surrounding the
piston C forms the space for the steam, in which the steam enters by the collar K
and passage v escaping by the slit w and the collar L. Passage vis shut or open
according to the position of the cock G. In the body H a slide F is arranged
shutting very tightly sideways and moving up and down which, so long as steam
enters into S through v, is in its lowest position, its undersurface touching the
circumference of C. In the position at the commencement, the steam entering
by reaches the narrow space between F and the flange or wing C₁ which have
been fastened by custing to C, and closely touches at the side and the circumference
the sides of B, and pushes the flange C away from F thus turning the piston C,
the axle D and the parts resting on the latter, the pulley T and the like.
If now by a corresponding revolving of C the further supply of steam is shut off,
the steam works between F and C¹ first of all by expansion until at length, when
CI passes the slit w, it begins to issue forth-F being at the same time drawn up
high in its appointed space I of the body H so that C¹ can pass freely under F,
and in consequence of the active force of the movable parts regain its original
position.
By revolving G, vis again opened, and at the same time F again lowered, the.
steam reissues forth between F and C, and the whole performance is once more
repeated. To set in motion F and G various mechanisms can be employed.
According to Sheet 1 F--which is hanging to the bracket M by the rods h, g, and f
and is continually drawn down by the spring i, is, by the pressure of the cam e,
placed on the disc O which rotates with D,-directed against the lower end (which
has been suitably equipped with the pulley d) of the rode which is carried
through the guide N and acts above upon the lever f.
Another contrivance to set F in motion is shown on Sheet 2, Figs. 4-6, in
side elevation, longitudinal and transverse section. Here the space I in which
F moves upwards is not furnished at the top with a stuffing-box, but finished off
as a massive cap H¹, being thus entirely closed.
Instead of which on the side in a special lid V a stuffing-box 41 is constructed,
in which a shaft 3 revolves which carries on the outer side a pinion 3, on the inner
a somewhat larger cog-wheel 24 the teeth of which gear with a rack Z on the one
surface of the slide F, so that F by the revolution of is raised in the one direction,
and lowered in the other. The revolving of 24 is effected by a traverse piece W,
|---which swinging round the pin wol at the bracket U having at one end a toothed
segment, at the other a pulley d, is ordinarily kept by means of the spring fl
in the position represented in Fig. 4, adjoining the peg st, but at every revolution
of the principal shaft D is moved once to the left (Fig. 4) by the cam e affixed to
the disc O which works towards the pulley d, in the direction of the arrow. While
this is going on, z acts upon the pinion 21 by which at the same time the shaft w²
and the larger cog-wheel revolve, the latter catching in the pinion 23. Through
these movements F in thus raised; when c has pressed d the spring f¹ draws
back the traverse piece W and with it all the other. parts into their former position
by which F is likewise again pushed downwards into the first position, as repre-
sented in Fig. 5.
The cock G is set in motion by the guide-pulley P together with the regulator Q.
(Figs. 1-3).
For this purpose P is composed of a number of discs lying close to each other
with a level descending edge k and the ascending edges k¹, k², k³, kª, placed towards
1

page_text: each other, and a lever p whose lower free end by means of a spring, continually
grazes P is so arranged that it can be pushed either to one side on its spindle t,
by means of the rectangular lever 7 which is pivoted to the bracket R and set in
motion by Q and which, by the pin n in the fork m of its lower end, is always
gearing with the groove o at the round head in front of p, thus alternately grazing
one or the other of the discs of P; or it can be pushed to the other side, when it
is raised or lowered by the latter, at the same time turning t, and the toothed
segment r attached to it, round a corresponding angle whereby, the cog-wheel s
which is fixed upon the spindle u of the cock G and is gearing with r, is made
to revolve.
In this manner an accurate self-acting alteration in the expansion directly
controlled by the regulator is rendered possible.
.
The piston C works at the same time as fly-wheel, but it is self-evident that a
separate fly-wheel might likewise be present."
