"
VICTOR CLEMENT JOSEPH ORTMANS, of Brussels, in the Kingdom of Belgiuin,
Civil Engineer, AN IMPROVED ROTATORY PUMP OR APPARATUS FOR RAISING AND
FORCING FLUIDS, APPLICABLE ALSO AS A MOTIVE-POWER ENGINE, AND FOR OTHER
PURPOSES."
My Invention relates to a novel construction of pumps or rotatory continuous
acting apparatus for raising and forcing hot or cold liquids or fluids, and for exhausting
or drawing in and compressing air or gas, the said apparatus being also applicable
as a steam or hydraulic motive-power engine, as a water meter, as a fan, and for
other purposes.
The body of the said pump or apparatus is of cylindrical form, with straight plain
sides, and is provided with suitable inlet and outlet passages or pipes. From the
central portion of each side of the said body of the pump or apparatus projects a
stuffing box, which stuffing boxes are traversed by a central shaft or axis upon
which is mounted within the pump or apparatus the nave or hoss of a circular plate
or disc made of cast iron or other suitable metal, and having the form of several
symmetrical segments of screws joined together, so that the said plate or disc
presents an undulating surface, the tops of the convex portions of which undulations
are constantly in contact with one or other of the sides of the body of the pump
alternately. The said undulating plate or disc extends from the nave or boss afore-
said upon the central shaft or axis to the periphery of the inside of the apparatus
where it forms a joint. The undulations of the plate or disc thus form with the
inner sides of the pump or apparatus chambers or compartments, separated one from
the other by the said plate or disc itself, the curved surfaces of which by passing

therein.
As it is requisite that the water or fluid acted upon by the rotation of the said
dise or plate, or acting upon the said disc or plate, should be prevented from passing
completely round the pump or apparatus, so as to return to the point where it
entered, and thus annihilate the useful effect of the apparatus, I dispose between
the inlet and outlet passages within the body of the pump or apparatus an obturating
slide or plate which traverses the body of the pump or apparatus, the ends of the
said obturating slide or plate being contained in boxes or chests formed to receive
them, one on each side of the body of the pump or apparatus, so that the said
obturating slide or plate is capable of lateral alternate motion across the pump or
apparatus, and at the same time is fluid-tight. In the said obturating slide or plate
is a slot perpendicular to the axis of the pump or apparatus. In the said slot is a
suitable swivel joint piece, through which the undulating plate or disc herein-before
described passes and slides, and the said undulating plate or disc, from its peculiar
shape and uniform thickness, is capable of rotating, and at the same time sliding or
passing through the said slot, and the rotatory motion of the said undulating plate
or disc has for effect to give motion to the obturating slide or plate, which thus
adapts itself automatically to the different positions of the curves.
To facilitate the sliding motion of the said obturating slide or plate when under
pressure and to prevent its wearing. I support it sometimes upon friction rollers, by
which means I am also enabled to regulate its height.
In some cases, instead of allowing the obturating slide or plate to be actuated by
the rotation of the undulating disc or plate inside the pump or apparatus as herein-
before described, I cause the required motion to be imparted to the said obturating
plate or disc from the outside of the pump or apparatus by means of suitable
eccentric or cam motion or by means of an undulating plate or disc of a shape
corresponding with that of the undulating plate or disc within the pump or
apparatus.

VICTOR CLEMENT JOSEPH ORTMANS. of Brussels, in the Kingdom of Belgium,
Civil Engineer. AN IMPROVED ROTATORY PUMP OR APPARATUS FOR RAISING AND
FORCING FLUIDS, APPLICABLE ALSO AS A MOTIVE-POWER ENGINE. AND FOR OTHER
PURPOSES."
My Invention relates to a novel construction of pumps or rotatory continuous
acting apparatus for raising and forcing hot or cold liquids or fluids. and for exhausting
or drawing in and compressing air or gas, the said apparatus being also applicable
as a steam or hydraulic motive-power engine, as a water meter, as a fan, and for
other purposes.
The body
the said pump or apparatus is of cylindrical form, with straight plain
sides, and is provided with suitable inlet and outlet passages or pipes. From the
central portion of each side of the said body of the pump or apparatus projects a
stuffing box, which stuffing boxes are traversed by a central shaft or axis, upon
which is mounted within the pump or apparatus the nave or boss of a circular plate
or disc made of cast iron or other suitable metal, and having the form of several
symetrical segments of screws jointed together, so that the said plate or disc presents
an undulating surface, the tops of the convex portions of which undulations are
constantly in contact with one or other of the sides of the body of the pump
alternately. The said undulating plate or disc extends from the nave or boss
aforesaid upon the central shaft or axis to the periphery of the inside of the
apparatus where it forms a joint. The undulations of the plate or disc thus form
with the inner sides of the pump or apparatus chambers of compartments, separated
one from the other by the said plate or disc itself, the curved surface of which by
passing from one side to the other side of the body of the pump or apparatus forms
partitions therein.
As it is requisite that the water or fluid acted upon by the rotation of the said
disc or plate, or acting upon the said disc or plate, should be prevented from passing
completely round the pump or apparatus, so as to return to the point where it
entered, and thus annihilate the useful effect of the apparatus. I dispose between
the inlet and outlet passages within the body of the pump or apparatus an obturating
slide or plate which traverses the body of the pump or apparatus, the ends of the
said obturating slide or plate being contained in boxes or chests formed to receive
them, one on each side of the body of the pump or apparatus, so that the said
obturating slide or plate is capable of lateral alternate motion across the pump or
apparatus, and at the same time is fluid-tight. In the said obturating slide or plate
is a slot, perpendicular to the axis of the pump or apparatus. In the said slot is
a suitable swivel joint piece, through which the undulating plate or disc herein-
before described passes and slides. and the said undulating plate or disc. from its .
peculiar shape and uniform thickness, is capable of rotating, and at the same time
sliding or passing through the said slot. and the rotatory motion of the said
undulating plate or disc has for effect to give motion to the obturating slide or
plate which thus adapts itself automatically to the different positions of the curves.
To facilitate the sliding motion of the said obturating slide or plate when under
pressure, and to prevent its wearing, I in some cases support it upon friction rollers,
by which means I am also enabled to regulate its height.
In some cases, instead of allowing the obturating slide or plate to be actuated
by the rotation of the undulating disc or plate inside the pump or apparatus as
herein-before described. I cause the required motion to be imparted to the said
obturating plate from the outside of the pump or apparatus by means of a suitable
excentric or cam motion, or by means of an undulating plate or disc of shape
corresponding with that of the undulated plate or disc within the pump or
apparatus,
:

page_text: Having thus explained the nature of my said Invention I will proceed to descrive
with reference to the accompanying Drawings the manner in which the same may
be performed.
Figure 1 represents in side elevation partially in section one half of the shell or
body, and the obturating slide of a pump or apparatus constructed according to
my Invention, the other half of the said shell or body being omitted.
Figure 2 is a transverse section of the said pump or apparatus.
Figure 3 is a sectional view of the same shewing the position of the obturating
slide or plate, and an arrangement for giving motion to it from outside the body of
the pump or apparatus.
Figure 4 is a front view of the rotatory plate or disc.
Figure 5 is an elevation of the obinrating slide or plate.
Figure 6 is a horizontal section of part of the apparatus shewing the obturating
slide or plate in its case or chest, and provided with anti-friction rollers and a swivel
joint piece traversed by the rotatory plate or disc.
Figure represents in horizontal and in vertical section a modification in the
construction of the obturating slide or plate.
The same letters of reference indicate like parts when they occur in the different
Figures of the Drawing.
A, A', are the two halves of the body or shell of the pump which are connected
together by bolts. The said body of the pump is formed with an inlet passage A²
and an outlet passage A³. and is provided with suitable stuffing boxes D, D',
traversed by the rotatory shaft C. Upon the said shaft is affixed the nave B of
the undulating plate or disc B', the undulations of which divide the inner part of
the pump into four separate chambers or compartments N (the number of compart-
ments N may however be varied); E is the obturating slide or plate which works
in the case or chest. El. (as seen in Figures 1,3, and 6). The said obturating slide
or plate E is slotted at E, as seen in Figure 5. and in the said slot. E² is placed a
swivel F. through which the undulating plate or disc B' works, the said swivel
having a slight angular motion to adapt itself to the plate or disc B': G. G, are
anti-friction rollers against which the obturating slide or plate E bears. (In some
cases the said anti-friction rollers may be dispensed with): L are strips of metal
forming a packing to the slide or plate E. and K is the packing within the swivel F
to insure a tight joint to the plate or disc B': H. (see Figures 1 and 3) is a metal
plate placed between the cover of the case or chest E', and the obturating slide or
plate E for the purpose of regulating the position of the said slide or plate E by
means of set screws J: M are metal plates or strips forming joints between the
sides of the pump and the rotatory plate or disc B'.
The action of the pump is as follows:---Motion having been communicated to the
rotatory shaft C, the undulating plate or disc B. B. is caused also to rotate and
draws in at A2 the fluid to be operated on, and carries it round to the outlet.
passage A, through which it is forced out. At the same time the said plate or disc
traversing the slot E2 in the obturating slide or plate E by its peculiar shape gives
a reciprocating transverse motion to the said obturating slide or plate E in the case
or chest E', so that the obturating slide or plate E while following the curved surface
of the rotatory plate or disc B¹ keeps it fluid-tight.
It will be readily understood that the pump or apparatus herein-before described
is also applicable as a steam or hydraulic motive-power engine, as a water meter, as
a fan or blowing machine, and as an extractor or exhauster of gas and fluids
generally.
In Figure 3 is represented a mechanical arrangement for imparting the required
motion to the obturating slide or plate E from the outside of the pump or apparatus;
Pis a cam mounted on the rotatory shaft C. The said cam P is formed on the
outside with a projecting flange or rim R curved to the same figure as the rotatory
plate or disc B' within the pump. The said flange or rim R passes between two
rollers S. S, mounted upon pins or studs affixed upon the plate S¹, which plate forms
one end of a rod T passing into the case or chest E' through a suitable stuffing box,

page_text: and by its other end connected to the obturating slide or plate E. By the rotation
of the shaft C the cam P is also caused to rotate, and the curved flange or rim R
acting on the rollers S, S. gives a reciprocating motion to the rod T, and consequently
to the slide or plate E, and as the flange or rim R, and the rotatory plate or disc B
are similarly curved, the slot E in the obturating slide or plate E will always be in
the required position to allow the plate or disc B' to pass through it, whatever be
the position of the said plate or disc.
Figure represents in horizontal and in vertical section a modification in the
construction of the obturating slide or plate, shewn in Figures 5 and 6; E is the
obturating slide or plate, and E2 is the slot through which the rotatory plate or
dise B', Figures 2 and 3 passes. On each side of the said slot E, Figure 7, is a
chamber in which is fitted a metal plate V, which plates V, V, are pressed outwards
by springs W, W, the power of the said springs being regulated by set screws as
shewn.
The rotatory plate or disc passes between the metal plates V. V, which press
it on both sides so as to keep the parts perfectly fluid-tight. The said metal
plates V, V, may be traversed by holes or channels to allow the water or fluid to
pass behind them, so as to equalize the pressure upon the said plates.
Having thus described the nature of my said Invention and the manner in which
the same may be performed, I wish it to be understood that I do not confine myself
to the precise details herein-before described and illustrated in the accompanying
Drawings, as the same may be varied without departing from the nature of my
said Invention, but I claim as my said Invention, the combination and arrangement
of parts of pumps or apparatus herein-before described, and illustrated in the
accompanying Drawings, that is to say, a cylindrical case or shell in which works a
rotatory undulated or curved plate or disc formed of undulatory helical segments,
so that its periphery is constantly in contact with the cylindrical inner surface of
the said case or shell, and that the tops or apices of the convex parts of the curves
or undulations are constantly in contact with either one or other of the inner flat
sides of the said case or shell, so as to form with the said case or shell a series of
internal chambers, the said plate or disc working through an obturating slide or plate
capable of reciprocatory motion essentially as and for the purposes herein-before
described.
In witness whereof. I. the said Victor Clement Joseph Ortmans, have here-
unto set my hand and seal, this Tenth day of January, in the year of our
Lord One thousand eight hundred and seventy-eight.
