An Improved Rotary Engine, suitable as Pump or Motor.
I, ARVID SVENSSON GUMOELIUS, Engineer, of 2, Drottninggatan, Stockholm,
Sweden, do hereby declare the nature of this invention to be as follows:—
This invention comprises a new rotary engine which can be utilised indifferently
as a water elevator or as a hydraulic motor; this apparatus in other words can.

is essentially characterized by a drum or cylinder in which there are arranged
wings of appropriate form put in movement, either under the action of an exterior
force in order to operate as suction and force pistons, or, under the action of the
water under pressure, traversing the apparatus, in order to communicate a rotary
movement to an axle on which they are mounted. These wings are besides com-
bined together and with guides and a diaphragm in order to take during their way
in the cylinder or body of the apparatus, different positions according as their
action as piston is or is not required.
The apparatus comprises a cylinder, forming the body of the engine closed at its
two extremities by covers of appropriate form. This cylinder is provided with two
pipes for the admission and the escape of the water and carries interiorly a packing
extending round a little more than a quarter of its interior circumference and a
further piece of packing playing the role of a diaphragm arranged in the other
half of the circumference of the cylinder, of which it fills the whole transversal
section, leaving only a passage free, the purpose of which will be explained herein-
after.
The one of the covers for instance is traversed by an axle ending at the middle

which has bearing in the other cover by a cylindrical trunnion is hollowed interiorly
and provided with two openings perpendicular to one another, giving passage to
two axles, of which the one is cranked in order to pass across the other axle. These
axles carry wings mounted in couples on the same axle in planes perpendicular
to one another. The one axle can turn freely in the opening of the sphere and the
other axle can move a quarter revolution on itself by the displacement of its cranked
part in the interior of this sphere.
On each side of the diaphragm which fills the section of the body of the pump
comprised between the covers the cylinder and the sphere there is disposed a guide
bent in a quarter of a circle starting from the diaphragm at the height of the
passage which is provided therein and ending in slight inclination against the
inner wall of the covers. When the main axle and the sphere are rotated from
the exterior the sphere by turning operates the wings and makes them run round
in the body of the engine. As each wing arrives opposite the outlet tube it meets
the under extremity of the guide pressing against the inclined plane of this guide,
this wing is obliged to turn on its axis causing consequently the turning of the
opposite wing on the same axle. The revolution being continued the first said

wing rises completely on the guide, takes a position completely parallel to the
plane of rotation of the engine and passes through the passage in the diaphragm
in which it passes with slight friction. The opposite wing in this movement has
meanwhile also turned a quarter turn and occupies a position vertical to the plane
of rotation rubbing with its periphery against the packing in which it has
passage. This wing produces thus in this part of the body of the engine an
aspiration which draws in the water through the admission tube if the apparatus
operates like a pump. This aspiration continues until the wing leaves the packing
and approaches the outlet tube. But at this moment its opposite wing leaving the
opening of the diaphragm meets the second guide which gradually returns it to
its vertical position, whilst the opposite wing, which operates as piston begins to
incline in order to be brought into position for its passage through the opening
of the diaphragm.
The other two wings act similarly intermediately between the former wings.
During a revolution of the main axle there is always one of the wings operating
as piston in the free space in the interior of the packing whilst the opposite wing
passes through the opening of the diaphragm and the two other wings between
occupy an inclined position.
The action is the same whichever be the direction of revolution of the main axle
the apparatus will operate in the same way when used as a hydraulic motor.
The wings may be of any form; thus they might be circular, in this case however
as the circular form of the wings would leave between themselves an empty space
and as between the passage of the two successive wings in the opening of the
diaphragm the latter would not be closed, it is necessary to combine with these
wings a plate in which the wings occupy a hole of a form similar to their own and
which by being displaced with these wings, secures the constant closing of the open-
ing in the diaphragm. The exterior form of the body of the engine will vary
evidently with the form of these wings, and in the case especially, of wings of
circular form, it will take an annular form composed simply of two pieces assembled
directly on one another.

An Improved Rotary Engine, suitable as Pump or Motor.
I, ARVID SVENSSON GUMOELIUS, Engineer, of 2, Drottninggatan, Stockholm,
in the Kingdom of Sweden, do hereby declare the nature of this invention and in
what manner the same is to be performed to be particularly described and ascer-
tained in and by the following statement:-
This invention comprises a new rotary engine which can be utilized either
as a water elevator or as a hydraulic motor; this apparatus in other words can
either elevate the water and drive it back under the action of an exterior driving
force or develop a driving force under the action of the water under pressure. It
is essentially characterized by a drum or cylinder in which there are arranged
wings of appropriate form put in movement, either under the action of an exterior
force in order to operate as suction and force pistons, or, under the action of the
water under pressure, traversing the apparatus, in order to communicate a rotary
movement to an axle on which they are mounted. These wings are besides com-
bined together and also with guides and a diaphragm in order to take during their
course in the cylinder or body of the apparatus, different positions according as
their action as pistons is or is not required.

page_text: In the annexed drawings, which represent an example of my invention. Fig. 1
shows a longitudinal section of an engine on line 1-2 of Fig. 2. Fig. 2 is a cross
section on line 3-4 of Fig. 1. Fig. 3 is a view in section and in perspective of
the whole of the engine. Figs. 4 and 5 are two views corresponding with those of
Figs. 1 and 2 but showing a variation of my invention.
The apparatus comprises a cylinder R forming the body of the engine and closed
at its two extremities by covers F and F of appropriate form. This cylinder R
is provided with two pipes J and K (Fig. 2) for the admission and the escape of
the water and carries interiorly a packing S extending round a little more than a
quarter of its interior circumference (see Figs. 1 & 2) and a further piece H of
packing playing the role of a diaphragm arranged in the other half of the circum-
ference of the cylinder R of which it fills the whole transversal section, leaving
only a passage h free, the purpose of which will be explained hereafter.
The one of the covers for instance is traversed by an axle A ending at the
middle of the cylinder R in a sphere B filling the free space between the
covers FF. This sphere B which has bearing in the other cover F by a cylindrical
trunion b is hollowed interiorly and provided with two openings E El perpen-
dicular to one another, giving passage to two axles D D¹ of which the one 1)¹ is
cranked in order to pass across the other axle D. These axles carry wings CC
CC mounted in couples on the same axle in planes perpendicular to one
another. The axle 1 can turn freely in the opening E of the sphere B and the
axle can move a quarter revolution on itself by the displacement of its cranked
part in the interior of this sphere B.
On each side of the diaphragm H which fills the section of the body of the pump
comprised between the covers F F1, the cylinder R and the sphere B there is dis-
posed a guide G bent in a quarter of a circle (see Fig. 2) starting from the
diaphragm H at the height of the passage h which is provided therein and ending
in a slight inclination against the inner wall of the covers F F¹.
When the main axle A, and the sphere are rotated from the exterior, the sphere
by turning operates the wings C C C C and makes them run round in the body
of the engine. This movement being operated for instance in the direction of the
arrow (Fig. 2) wing C arrives opposite the outlet tube J it meets the under
extremity of the guide G pressing against the inclined plane of this guide, this
wing C is obliged to turn on its axis causing consequently the turning of the
opposite wing on the same axle D'. The revolution being continued the wing C
rises completely on the guide G takes a position completely parallel to the plane
of rotation of the engine and passes through the passage h in the diaphragm H in
which it passes with slight friction (see Fig. 1 the corresponding position of the
wing C). The opposite wing C in this movement has meanwhile also turned a
quarter turn and occupies a position vertical to the plane of rotation rubbing with
its periphery against the packing $ (Figs. 1 & 2) in which it has a tight passage.
This wing produces thus in this part of the body of the engine an aspiration which
draws in the water through the admission tube K if the apparatus operates like
a pump. This aspiration continues until the wing leaves the packing S and
approaches the outlet tube J. But at this moment the opposite wing C leaving
the opening of the diaphragm meets the second guide G which gradually returns
it to its vertical position, whilst the opposite wing C which operates as a piston
begins to incline in order to be brought into position for its passage through the
opening of the diaphragm.
At the moment when this wing C leaves the packing S, it is replaced at the
entrance of the part of the body of the pump provided with this packing, by the
wing C arrived completely at the vertical position whilst the opposite wing C
traverses the opening of the diaphragm H. This wing C then begins to operate
in its turn as suction piston operating simultaneously in order to drive back through
the opening J the water drawn in the previous quarter revolution by the wing C¹.
During a revolution of the main axle A (as can be seen from the annexed draw-

page_text: ings) there is always one of the wings operating as a piston in the free space in the
interior of the packing S whilst the opposite wing passes through the opening of
the diaphragm H and the two other wings between occupy an inclined position.
The action is the same whichever be the direction of revolution of the main
axle A. Whichever the direction of movement of the wings in the drum R,
their positions are always operated by the one or the other of the guides G and as
the position of one of the wings determines that of the opposite wing keyed on
the same axle, the same positions are repeated successively for each wing.
It may also be stated that the engine could according to the direction of revolu-
tion draw in through the pipe K and drive out through the pipe J or vice versa.
If instead of putting the axle A into rotation from the exterior and instead of insert-
ing the engine between an inlet and an outlet pipe it is connected with a pipe
supplying water under pressure the apparatus will operate in the same way as
hydraulic motor, the water under pressure arriving for instance through the pipe K
will operate on the wing C for instance (see Fig. 2) like on a piston and will pro-
voke its displacement in the inner packing S of the cylinder I until the moment
when this wing leaving this packing will be replaced by the wing C¹ the plane of
which will have become perpendicular to the plane of Fig. 2.
In the one or the other case, that is to say, when the apparatus operates as a
pump or as motor, the necessary tightness will be secured, on the one side, by the
packing S adapted exactly to the contour of the wings and on the other side, by
the diaphragm H the only opening of which is constantly closed by the wing which
traverses it.
It will be also necessary that the contact surfaces between the wings and the
sphere B and between the latter and the near parts of the covers F' F' are perfectly
finished in order to secure the tightness of the apparatus.
The wings C C C C may be of any form; thus they might be circular as shown
in Figs. 4 and 5 of the annexed drawings in this case however, as the circular
form of the wings would leave between themselves an empty space and as between
the passage of the two successive wings in the opening of the diaphragm the latter
would not be closed, it is necessary to combine with these wings a movable plate U
in which the wings occupy a hole of a form similar to their own and which, by
being displaced with these wings, secures the constant closing of the opening in
the diaphragm. The exterior form of the body of the engine will vary evidently
with the form of these wings, and in the case especially of wings of circular form
it will take as shown in Fig. 4, an annular form composed simply of two pieces F F
assembled directly on one another.
Having now particularly described and ascertained the nature of this
invention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. An improved rotary engine suitable as a suction and pressure pump or as a
hydraulic motor having wings C C C C movable in a body or cylinder and
mounted in couples at right angles to one another, on two axles crossing one another
at a right angle in a hollow sphere placed in the centre of the body of the engine
and connected with an axle A extending to the exterior of the engine, in order that
these wings can successively operate in a part of the body of the apparatus, as
suction pistons or as driving pistons, and take different positions with regard to
one another according if they are active or inactive.
2. In an engine as in Claim 1, the combination of movable wings with a packing S
extending in a part of the body of the engine, in which part the wings operate
successively as pistons, and with a diaphragm H occupying the whole transversal
section of the other part of the body of the engine and provided with an opening
in order to give passage to the wings in a plane perpendicular to that in which
they operate as pistons, in which plane these wings are brought by guides G
arranged each on a side of the diaphragm and operating their relative positions.
3. A form of construction of the apparatus as in Claims 1 and 2 wherein the

page_text: wings are combined with a movable plate in which they occupy a hole of a form
similar to their own said plate being intended to fill the space between two succes-
sive wings in order to maintain the opening of the diaphragm continually
closed.
